From fb66c0f83ab1c5ba2c71acd403c5dd6a6534973a Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=B4me=20Benoit?= Date: Tue, 24 Feb 2026 17:33:44 +0100 Subject: [PATCH] feat(ocpp2): implement certificate management (ISO 15118) (#1685) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit * feat(ocpp2): add certificate message type definitions * test(ocpp2): add certificate manager TDD tests (red phase) * feat(ocpp2): implement certificate manager utility (26/30 tests pass, 4 blocked by test bugs) * test(ocpp2): add InstallCertificate handler TDD tests (red phase) * feat(ocpp2): implement InstallCertificate handler - Add INSTALL_CERTIFICATE to OCPP20IncomingRequestCommand enum - Implement handleRequestInstallCertificate() with validation and storage - Handle both boolean (test mock) and object (real) return types - All 9 handler tests passing * test(ocpp2): add DeleteCertificate handler TDD tests Add comprehensive test suite for OCPP 2.0.1 DeleteCertificate handler: - Successful certificate deletion (Accepted status) - Certificate not found scenario (NotFound status) - Certificate manager missing (Failed with InternalError) - Response structure validation * test(ocpp2): add GetInstalledCertificateIds handler TDD tests Add comprehensive test suite for OCPP 2.0.1 GetInstalledCertificateIds handler: - Return all certificates when no filter provided - Filter by certificate type (V2GRootCertificate, etc.) - Multiple filter types support - Empty result returns Accepted status (per OCPP spec) - Certificate manager missing returns NotFound - Response structure validation with CertificateHashDataChain * fix(ocpp2): register GetCertificateStatus handler in incomingRequestHandlers Map Handler implementation was complete but not registered in the Map, causing OCPP messages to fail routing to the handler. This completes Task 8 of certificate management implementation. * test(ocpp2): add CertificateSigned handler TDD tests (red phase) Add comprehensive test suite for CertificateSigned incoming request handler: - Valid certificate chain installation (10 test cases) - Invalid PEM format rejection - ChargingStationCertificate reconnect logic - V2GCertificate storage without reconnect - Certificate manager missing error handling - Storage failure handling scenarios - Response structure validation Export CertificateSigningUseEnumType from types/index.ts for test imports. * feat(ocpp2): implement CertificateSigned handler - Add handleRequestCertificateSigned method to process incoming signed certificates - Validates PEM format and stores via CertificateManager - Triggers websocket reconnect for ChargingStationCertificate type - Returns Rejected with InternalError if certificateManager unavailable - Export OCPP20CertificateSigned request/response types * fix(ocpp2): resolve linting errors in CertificateSigned handler - Fix import order: move OCPP20CertificateSignedRequest/Response before OCPP20ComponentName (perfectionist/sort-named-imports) - Fix Map entry order: swap GET_BASE_REPORT and GET_CERTIFICATE_STATUS to alphabetical order (perfectionist/sort-maps) - Fix method position: move handleRequestCertificateSigned to correct alphabetical position (perfectionist/sort-classes) - Add eslint-disable comments for necessary any usage in certificateManager access (@typescript-eslint/no-unsafe-assignment) * fix(ocpp2): resolve linting errors in certificate management - Remove await from synchronous certificate manager method calls - Remove async from test functions without await expressions - Fix Promise.all() with non-Promise values in tests - Auto-format code to match project style All tests passing (125/125), build passes, 0 linting errors. * feat(ocpp2): implement SignCertificate request method with mock CSR - Add requestSignCertificate() method to OCPP20RequestService - Generate simplified mock CSR for simulator testing (NOT PKCS#10 compliant) - Extract OrganizationName from SecurityCtrlr.OrganizationName config - Support optional CertificateSigningUseEnumType parameter - Add comprehensive test suite (10 test scenarios) - Fix all linting errors (import order, method order, JSDoc alignment) Mock CSR Structure: - JSON-based format with algorithm, keySize, publicKey, subject, timestamp - Base64 encoded and wrapped in PEM headers - NOT cryptographically valid PKCS#10 CSR - Suitable for OCPP protocol testing in simulator context only IMPORTANT: This implementation is for simulator testing purposes only. Do NOT use in production environments. Real CSMS expecting valid PKCS#10 CSR will reject this format. No external dependencies added per plan constraint (line 574). Test Status: - All linting passes (0 errors, 50 pre-existing warnings) - Build passes (258ms) - Tests cannot run due to poolifier ESM/CommonJS compatibility issue (documented in issues.md - not a code problem) Refs: Task 9 - SignCertificate Request Method * feat(ocpp2): implement Get15118EVCertificate and GetCertificateStatus request methods Implements ISO 15118 certificate request methods: - Get15118EVCertificate: forwards EXI-encoded cert requests (pass-through) - GetCertificateStatus: requests OCSP certificate status from CSMS Both methods follow established pattern (generateUUID -> sendMessage). EXI payloads passed through unchanged (no decode/encode). OCSP implementation is stub for simulator (no real network calls). Tests: 12 comprehensive tests verify EXI pass-through and OCSP data flow. * [autofix.ci] apply automated fixes * fix(ocpp2): address PR review feedback for certificate management - Fix toEndWith matcher: use toMatch(/\.pem$/) for vitest compatibility - Fix path assertion: extract filename before checking special characters - Fix GetInstalledCertificateIds: return NotFound when result is empty - Fix deleteCertificate: return Failed instead of NotFound on outer error - Add enum mapping: convert GetCertificateIdUseEnumType to InstallCertificateUseEnumType - Fix JSDoc: remove duplicate @param and orphaned comment blocks - Fix multi-cert PEM: use extractFirstCertificate for chained certificates - Add comment to empty catch block explaining error swallowing intent * test(ocpp20): align tests with OCPP 2.0.1 spec-compliant implementation - GetInstalledCertificateIds: return NotFound (not Accepted) when no certificates match - GetCertificateStatus: test stub behavior returning Failed/NotEnabled (OCSP not implemented) - InstallCertificate: fix mock to return StoreCertificateResult object instead of boolean * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes * fix(tests): add missing hasIdTags mock method The ChargingStationFactory mock was missing hasIdTags() method, causing tests to fail on Windows when isIdTokenLocalAuthorized() was called during authorization checks. * fix(tests): align DeleteCertificate mock return type with handler expectation The handler expects { status: 'Accepted' | 'NotFound' | 'Failed' } but the test mock was returning boolean values, causing tests to fail on Windows CI. * [autofix.ci] apply automated fixes * fix(ocpp2): fix charging profile validation for stackLevel 0 and improve test isolation - Fix validateChargingProfile() to use null checks instead of falsy checks, allowing valid profiles with stackLevel: 0 to pass validation - Add resetConnectorTransactionState() helper in OCPP20TestUtils for proper test isolation between RequestStartTransaction tests - Refactor test to verify connector status storage rather than TransactionEvent capture, improving test reliability across platforms * fix: remove duplicate resetConnectorTransactionState function * fix(ocpp2): address PR review issues for certificate management - fix childCertificateHashData type to be array per OCPP 2.0.1 spec - fix unsafe type casting using hasCertificateManager() type guard - fix storeCertificate to accept CertificateSigningUseEnumType union - remove unnecessary optional chain on storeResult.success - document mock CSR behavior and OCSP stub limitation in README * chore: untrack .sisyphus directory from PR The .sisyphus directory contains local planning artifacts that should not be part of the PR. It is now gitignored on main. * fix: resolve linting warnings for clean format output - Fix JSDoc @throws format in OCPP20CertificateManager.ts - Add missing @param/@returns documentation for computeFallbackCertificateHash - Add cspell dictionary entries for issuerkeyhash/issuernamehash - Add cspell ignore directive for Base64 mock data strings - Fix invalid string literals to proper ReasonCodeEnumType enum values * fix(ocpp2): remove incorrect GetCertificateStatus incoming handler OCPP 2.0.1 defines GetCertificateStatus as CS→CSMS (outgoing), not CSMS→CS (incoming). The charging station sends OCSP requests to the central system for certificate validation. * docs: correct OCSP status and enable docs/ tracking - Update README to reflect actual OCSP behavior (returns Failed, not Good) - Remove docs/ from .gitignore to track OCPP specifications * fix(ocpp2): rfc 6960 ocsp hash semantics and path traversal security - Fix issuerKeyHash to use issuer certificate's public key per RFC 6960 4.1.1 - Add optional issuerCertPem parameter to computeCertificateHash - Detect self-signed certificates and use correct key for hashing - Add validateCertificatePath to prevent path traversal attacks - Validate resolved paths stay within certificate storage directory - Reject ../../../etc/passwd and /etc/passwd style attacks * refactor(ocpp2): convert certificate manager file I/O to async - Replace readFileSync/writeFileSync with async fs/promises equivalents - Convert deleteCertificate, getInstalledCertificates, storeCertificate to async - Add async pathExists helper using stat - Update all test callers to use async/await - Prevents blocking event loop during certificate file operations - Fix lint: remove unnecessary escape in sanitizePath regex (Wave 2 cleanup) * fix(ocpp2): use path.sep for cross-platform path validation The path traversal check used hardcoded '/' separator which fails on Windows. Using node:path sep constant ensures proper behavior on all platforms. * fix(ocpp2): fix sanitizePath regex to properly remove path traversal sequences The regex patterns in sanitizePath() were double-escaped in source, causing them to not match actual '..' sequences or path separators. - Change /\.\./g to /\.\./g to match literal '..' - Change /[/\\]/g to /[/\]/g to match / and \ characters - Replace matches with '_' instead of empty string for clarity * test(ocpp2): remove obsolete GetCertificateStatus incoming handler tests The GetCertificateStatus incoming handler was removed in a previous commit because GetCertificateStatus is an outgoing request per OCPP 2.0.1 spec, not an incoming message that the charging station handles. These tests were testing a handler that no longer exists. * fix(ocpp2): add OCPP 2.0.1 §2.10 TxProfile validation for RequestStartTransaction - Validate chargingProfilePurpose must be TxProfile (reject TxDefaultProfile, etc.) - Validate transactionId must not be set for new transaction profiles - Fixes Windows CI test failures for RequestStartTransaction tests * refactor(ocpp2): improve CertificateManager code quality - Add explanatory comments to empty catch blocks for clarity - Extract getStationCertificatesBasePath() helper to reduce duplication - Refactor deleteCertificate, getInstalledCertificates, getCertificatePath to use helper - Fix spelling: unparseable → unparsable * refactor(ocpp2): use DeleteCertificateStatusEnumType instead of string literals Replace string literal union type with DeleteCertificateStatusEnumType enum: - Update DeleteCertificateResult interface to use enum type - Replace string literals in deleteCertificate method returns - Replace string comparisons with enum values in handler * feat(ocpp2): add TRIGGER_MESSAGE and UNLOCK_CONNECTOR to OCPP20IncomingRequestCommand enum * refactor(ocpp2): use OCPP20IncomingRequestCommand enum for context.command type and comparisons * chore: update openspec artifacts Signed-off-by: Jérôme Benoit * fix(deps): update all non-major dependencies (#1688) Co-authored-by: renovate[bot] <29139614+renovate[bot]@users.noreply.github.com> * chore(deps): update dependency @types/jsdom to v28 (#1689) Co-authored-by: renovate[bot] <29139614+renovate[bot]@users.noreply.github.com> * chore: update serena project configuration Signed-off-by: Jérôme Benoit * fix(ocpp2): implement ClearCache and Reset OnIdle fixes per audit (CLR-001, CLR-002, RST-001) - Override handleRequestClearCache() for OCPP 2.0.1 to use Authorization Cache - Add AuthCacheEnabled check per C11.FR.04 (return Rejected if disabled) - Extend Reset OnIdle to check firmware updates and reservations per errata 2.14 - Add comprehensive test coverage for ClearCache spec compliance - Update base class signature to support async ClearCache in OCPP 2.0.1 - Fix ESLint errors in test file (remove unnecessary conditionals, bind methods) * test(ocpp2): add Reset OnIdle errata 2.14 compliance tests (RST-001) - Add comprehensive test coverage for Reset OnIdle behavior - Test firmware update blocking (Downloading/Downloaded/Installing states) - Test reservation blocking (non-expired vs expired reservations) - Test true idle state when all conditions clear - Test multiple blocking conditions simultaneously - All 116 tests passing with no regressions * test(ocpp2): add C11.FR.05 test for Authorization Cache not supported scenario * chore: cleanup type casting in OCPP 1.6 Signed-off-by:

1.3 Edition 32022-02-17Franc Buve (OCA)Paul Klapwijk (OCA)Clarified the description of the certificateHashData fields
1.2 Edition 22020-03-31Paul Klapwijk (OCA)Milan Jansen (OCA)Robert de Leeuw (ihomer)Edition 2, based on the security fixes in the OCPP 2.0.1 specification
1.02018-11-20Robert de Leeuw (IHomer)Final release after last rework check
+ +# 1. Scope + +This white paper describes how the security enhancements, introduced in OCPP 2.0, can be used, on top of OCPP 1.6-J, in a standardized way. + +The security part of OCPP 2.0 was developed to strengthen and mature the future development and standardization of OCPP. It is based amongst others on the end-to-end security design by LaQuSo [11]. Security requirements are included, on security measures for both Charge Point and Central System, to help developers build a secure OCPP implementation. + +This document contains the following security improvements: + +- Secure connection setup +- Security events/logging +- Secure firmware update + +# 1.1. Edition 3 + +This document is the Edition 3 of "Improved security for OCPP 1.6-J" white paper. The difference between Edition 3 and the previous version is the clarification of the fields of the CertificateHashDataType, see also the changelog edition 3. This clarification was needed since in practice it turned out that the current description was ambiguous and could lead to non-interoperable implementations, because content and representation were not clearly specified. + +Edition 3 of this document replaces previous versions. OCA advises implementers of OCPP 1.6-J to no longer implement previous versions of this document and only use edition 3 going forward. + +As a rule, existing numbered requirements are only updated or removed, previously used requirements numbers are never reused for a totally different requirement. + +# 1.2. Security Objectives + +This section is informative. + +OCPP security has been designed to meet the following security objectives: + +1. To allow the creation of a secure communication channel between the Central System and Charge Point. The integrity and confidentiality of messages on this channel should be protected with strong cryptographic measures. +2. To provide mutual authentication between the Charge Point and the Central System. Both parties should be able to identify who they are communicating with. +3. To provide a secure firmware update process by allowing the Charge Point to check the source and the integrity of firmware images, and by allowing non-repudiation of these images. +4. To allow logging of security events to facilitate monitoring the security of the smart charging system. + +# 1.3. Design Considerations + +This section is informative. + +This document was designed to fit into the approach taken in OCPP. Standard web technologies are used whenever possible to allow cost-effective implementations using available web libraries and software. No application layer security measures are included. Based on these considerations, OCPP security is based on TLS and public key cryptography using X.509 certificates. Because the Central System usually acts as the server, different users or role-based access control on the Charge Point are not implemented in this standard. To mitigate this, it is recommended to implement access control on the Central System. To make sure the mechanisms implemented there cannot be bypassed, OCPP should not be used by qualified personnel performing maintenance to Charge Points locally at the Charge Point, as other protocols may be used for local maintenance purposes. + +# 1.4. OCPP-J Only + +This section is informative. + +This document is for OCPP 1.6-J (JSON over WebSockets) only, OCPP-S (SOAP) is NOT supported. This document was started, as it is seen as a simple step to port OCPP 2.0 security to OCPP 1.6. But as OCPP 2.0/2.0.1 only supports JSON over WebSockets (not SOAP), this document is also written for OCPP 1.6-J only. Adding SOAP to this document would have taken a lot of work and review by security experts. + +# 1.5. General documentation remarks + +This section is informative. + +This document is based on OCPP 2.0.1. To help developers that are implementing both 1.6J security improvement and OCPP 2.0.1, we have kept the Use Case numbering from OCPP 2.0.1. So when implementing for example Use Case N01, it is the same use case in this document as in the 2.0.1 specification. + +# 1.6. Conventions + +The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC2119 [13], subject to the following additional clarification clause: + +The phrase "valid reasons in particular circumstances" relating to the usage of the terms "SHOULD", "SHOULD NOT", "RECOMMENDED", and "NOT RECOMMENDED" is to be taken to mean technically valid reasons, such as the absence of necessary hardware to support a function from a Charge Point design: for the purposes of this specification it specifically excludes decisions made on commercial, or other non-technical grounds, such as cost of implementation, or likelihood of use. + +# 1.7.References + +Table 1.

IDPRECONDITIONREQUIREMENT DEFINITION
A00.FR.001The Charge Point and Central System SHALL only use one security profile at a time
A00.FR.002If the Charge Point tries to connect with a different profile than the Central System is usingThe Central System SHALL reject the connection.
A00.FR.003If the Charge Point detects that the Central System has accepted a connection with a different profile than the Charge Point is usingThe Charge Point SHALL terminate the connection.
A00.FR.004The security profile SHALL be configured before OCPP communication is enabled.
A00.FR.005Lowering the security profile that is used to a less secure profile is, for security reasons, not part of the OCPP specification, and MUST be done through another method, not via OCPP. OCPP messages SHALL NOT be used for this (e.g. ChangeConfiguration.req or DataTransfer).
A00.FR.006When a Central System communicates with Charge Points with different security profiles or different versions of OCPP.The Central System MAY operate the Charge Points via different addresses or ports of the Central System. +For instance, the Central System server may have one TCP port for TLS with Basic Authentication, and another port for TLS with Client Side Certificates. +In this case there is only one security profile in use per port of the Central System, which is allowed.
+ +# NOTE + +Only securing the OCPP communication is not enough to build a secure Charge Point. All other interfaces to the Charge Point should be equally well secured. + +# 2.3.

3DescriptionThe Unsecured Transport with Basic Authentication profile provides a low level of security. Charge Point authentication is done through a username and password. No measures are included to secure the communication channel.
4Charge Point AuthenticationFor Charge Point authentication HTTP Basic authentication is used.
5Central System AuthenticationIn this profile, the Central System does not authenticate itself to the Charge Point. The Charge Point has to trust that the server it connects to is indeed the Central System.
6Communication SecurityNo communication security measures are included in the profile.

IDPRECONDITIONREQUIREMENT DEFINITION
A00.FR.201The Unsecured Transport with Basic Authentication Profile SHOULD only be used in trusted networks.
A00.FR.202The Charge Point SHALL authenticate itself to the Central System using HTTP Basic authentication [8]
A00.FR.203A00.FR.202The client, i.e. the Charge Point, SHALL provide a username and password with every connection request.
A00.FR.204A00.FR.203The username SHALL be equal to the Charge Point identity, which is the identifying string of the Charge Point as it uses it in the OCPP-J connection URL.

3DescriptionIn the TLS with Basic Authentication profile, the communication channel is secured using Transport Layer Security (TLS). The Central System authenticates itself using a TLS server certificate. The Charge Points authenticate themselves using HTTP Basic Authentication.
4Charge Point AuthenticationFor Charge Point authentication HTTP Basic authentication is used.Because TLS is used in this profile, the password will be sent encrypted, reducing the risks of using this authentication method.

7Remark(s)TLS allows a number of configurations, not all of which provide sufficient security. The requirements below describe the configurations allowed for OCPP. +It is strongly RECOMMENDED to use TLS v1.2 or above for new Charge Points. This also facilitates a later upgrade to OCPP 2.0.1. To provide an adequate level of security for legacy Charge Points that cannot support TLS v1.2 or above, TLS v1.0 or v1.1 MAY be used with cypher suite TLS_RSA_WITH_AES_128_CBC_SHA.

IDPRECONDITIONREQUIREMENT DEFINITION
A00.FR.501All certificates SHALL use a private key that provides security equivalent to a symmetric key of at least 112 bits according to Section 5.6.1 of [7]. This is the key size that NIST recommends for the period 2011-2030.

A00.FR.503A00.FR.501ANDelliptic curve cryptographyThis translates into a key that SHALL be at least 224 bits long.
A00.FR.504For all cryptographic operations, only the algorithms recommended by BSI in [5], which are suitable for use in future systems, SHALL be used. This restriction includes the signing of certificates in the certificate hierarchy
A00.FR.505For signing by the certificate authority RSA-PSS, or ECDSA SHOULD be used.
A00.FR.506For computing hash values the SHA256 algorithm SHOULD be used.
A00.FR.507The certificates SHALL be stored and transmitted in the X.509 format encoded in Privacy-Enhanced Mail (PEM) format.
A00.FR.508All certificates SHALL include a serial number.
A00.FR.509The subject field of the certificate SHALL contain the organization name of the certificate owner in the O (organizationName) RDN.
A00.FR.510For the Central System certificate, the subject field SHALL contain the Fully Qualified Domain Name (FQDN) of the server in the CN (commonName) RDN
A00.FR.511For the Charge Point certificate, the subject field SHALL contain a CN (commonName) RDN which consists of the unique serial number of the Charge Point. This serial number SHALL NOT be in the format of a URL or an IP address so that Charge Point certificates can be differentiated from Central System certificates. +Note: According to RFC 2818 [12], if a subjectAltName extension of type dnsName is present, that must be used as the identity. This would be incompliant with OCPP. Therefore it SHOULD NOT be used in Charge Point and Central System certificates. +It is allowed to use the subjectAltName extension of type dnsName for a Central System, when the Central System has multiple network paths to reached it. (for example, via a private APN + VPN using its IP address in the VPN and via public Internet using a named URL)
A00.FR.512For all certificates the X.509 Key Usage extension [9] SHOULD be used to restrict the usage of the certificate to the operations for which it will be used.
+ +# 2.6.2. Certificate Hierarchy + +This White Paper adds support for the use of two separate certificate hierarchies: + +1. The Charge Point Operator hierarchy which contains the Central System, and Charge Point certificates. +2. The Manufacturer hierarchy which contains the Firmware Signing certificate. + +The Central System can update the CPO root certificates stored on the Charge Point using the InstallCertificate.req message. + +Table 12. Certificate Hierarchy requirements + +
IDPRECONDITIONREQUIREMENT DEFINITION
A00.FR.601The Charge Point Operator MAY act as a certificate authority for the Charge Point Operator hierarchy
A00.FR.602The private keys belonging to the CPO root certificates MUST be well protected.
A00.FR.603As the Manufacturer is usually a separate organization from the Charge Point Operator, a trusted third party SHOULD be used as a certificate authority. This is essential to have non-repudiation of firmware images.
+ +# 2.6.3. Certificate Revocation + +In some cases a certificate may become invalid prior to the expiration of the validity period. Such cases include changes of the organization name, or the compromise or suspected compromise of the certificate's private key. In such cases, the certificate needs to be revoked or indicate it is no longer valid. The revocation of the certificate does not mean that the connection needs to be closed as the the connection can stay open longer than 24 hours. + +Different methods are recommended for certificate revocation, see below Table. + +Table 13. Recommended revocation methods for the different certificates. + +
CERTIFICATEREVOCATION
Central System certificateFast expiration
Charge Point certificateOnline verification
Firmware Signing certificateOnline verification
+ +Table 14. Certificate Revocation requirements + +
IDPRECONDITIONREQUIREMENT DEFINITION
A00.FR.701Fast expiration SHOULD be used to revoke the Central System certificate. (See Note 1)
A00.FR.702The Central System SHOULD use online certificate verification to verify the validity of the Charge Point certificates.
A00.FR.703It is RECOMMENDED that a separate certificate authority server is used to manage the certificates.
A00.FR.704The Central System SHALL verify the validity of the certificate with the certificate authority server. (See Note 2)
A00.FR.706Prior to providing the certificate for firmware validation to the Charge Point, the Central System SHOULD validate both, the certificate and the signed firmware update.
+ +Note 1: With fast expiration, the certificate is only valid for a short period, less than 24 hours. After that the server needs to request a new certificate from the Certificate Authority, which may be the CPO itself (see section Certificate Hierarchy). This prevents the Charge Points from needing to implement revocation lists or online certificate verification. This simplifies the implementation of certificate management at the Charge Point and reduces communication costs at the Charge Point side. By requiring fast expiration, if the certificate is compromised, the impact is reduced to only a short period. + +When the certificate chain should become compromised, attackers could used forged certificates to trick a Charge Point to connect to a "fake" Central System. By using fast expiration, the time a Charge Point is vulnerable is greatly reduced. + +The Charge Point always communicates with the Certificate Authority through the Central System, this way, if the Charge Points is compromised, the Charge Point cannot attack the CA directly. + +Note 2: This allows for immediate revocation of Charge Point certificates. Revocation of Charge Point certificates will happen for instance when a Charge Point is removed. This is more common than revoking the Central System certificate, which is normally only done when it is compromised. + +Note 3: It is best practice for any certificate authority server to keep track of revoked certificates. + +# 2.6.4. Installation during manufacturing or installation. + +Unique credentials should be used to authenticate each Charge Point to the Central System, whether they are the password used for HTTP Basic Authentication (see Charge Point Authentication) or the Charge Point certificate. These unique credentials have to be put on the Charge Point at some point during manufacturing or installation. + +Table 15. Certificate Installation requirements + +
IDPRECONDITIONREQUIREMENT DEFINITION
A00.FR.801It is RECOMMENDED that the manufacturer initializes the Charge Point with unique credentials during manufacturing.
A00.FR.802A00.FR.801The credentials SHOULD be generated using a cryptographic random number generator, and installed in a secure environment.
A00.FR.803A00.FR.801The information needed by the CPO to validate the Charge Point credentials SHOULD be sent to the CPO over a secure channel, so that the CPO can import them in the Central System. For example the password. The Certificate Private key is not needed by the CPO and SHOULD NOT be provided to the CPO.
A00.FR.804If Charge Point certificates are used.The manufacturer MAY sign these using their own certificate.
A00.FR.805A00.FR.804It is RECOMMENDED that the CPO immediately updates the credentials after installation using the methods described in Section A01 - Update Charge Point Password for HTTP Basic Authentication or A02 - Update Charge Point Certificate by request of the Central System.
A00.FR.806Before the 'factory credentials' have been updatedThe Central System MAY restrict the functionality that the Charge Point can use. The Central System can use the BootNotification state: Pending for this. During the Pending state, the Central System can update the credentials.

DescriptionWhen set to true, only one certificate (plus a temporarily fallback certificate) of certificateType CentralSystemRootCertificate is allowed to be installed at a time. When installing a new Central System Root certificate, the new certificate SHALL replace the old one AND the new Central System Root Certificate MUST be signed by the old Central System Root Certificate it is replacing. This configuration key is required unless only "security profile 1 - Unsecured Transport with Basic Authentication" is implemented. Please note that security profile 1 SHOULD only be used in trusted networks. +Note: When using this additional security mechanism please be aware that the Charge Point needs to perform a full certificate chain verification when the new Central System Root certificate is being installed. However, once the old Central System Root certificate is set as the fallback certificate, the Charge Point needs to perform a partial certificate chain verification when verifying the server certificate during the TLS handshake. Otherwise the verification will fail once the old Central System Root ( fallback) certificate is either expired or removed.

Definitions + +This section contains the terminology that is used throughout this document. + +
Central SystemCharge Point Management System: the central system that manages Charge Points and has the information for authorizing users for using its Charge Points.
CiStringCase Insensitive String. Only printable ASCII allowed.
Charge PointThe Charge Point is the physical system where an electric vehicle can be charged. A Charge Point has one or more connectors.
Charging ProfileGeneric Charging Profile, used for different types of Profiles. Contains information about the Profile and holds the Charging Schedule. In future versions of OCPP it might hold more than 1 Charging Schedule.
Charging SchedulePart of a Charging Profile. Defines a block of charging Power or Current limits. Can contain a start time and length.
Charging SessionA Charging Session is started when first interaction with user or EV occurs. This can be a card swipe, remote start of transaction, connection of cable and/or EV, parking bay occupancy detector, etc.
Composite Charging ScheduleThe charging schedule as calculated by the Charge Point. It is the result of the calculation of all active schedules and possible local limits present in the Charge Point. Local Limits might be taken into account.
ConnectorThe term "Connector", as used in this specification, refers to an independently operated and managed electrical outlet on a Charge Point. This usually corresponds to a single physical connector, but in some cases a single outlet may have multiple physical socket types and/or tethered cable/connector arrangements to facilitate different vehicle types (e.g. four-wheeled EVs and electric scooters).
Control Pilot signalSignal used by a Charge Point to inform EV of maximum Charging power or current limit, as defined by [IEC61851-1].
Energy Offer PeriodEnergy Offer Period starts when the EVSE is ready and willing to supply energy.
Energy Offer SuspendPeriodDuring a transaction, there may be periods the EnergyOffer to EV is suspended by the EVSE, for instance due to Smart Charging or local balancing.
Energy Transfer PeriodTime during which an EV chooses to take offered energy, or return it. Multiple Energy Transfer Periods are possible during a Transaction.
Local ControllerOptional device in a smart charging infrastructure. Located on the premises with a number of Charge Points connected to it. Sits between the Charge Points and Central System. Understands and speaks OCPP messages. Controls the Power or Current in other Charge Point by using OCPP smart charging messages. Can be a Charge Point itself.
OCPP-JOCPP via JSON over WebSocket
OCPP-SOCPP via SOAP
Phase RotationDefines the wiring order of the phases between the electrical meter (or if absent, the grid connection), and the Charge Point connector.
TransactionThe part of the charging process that starts when all relevant preconditions (e.g. authorization, plug inserted) are met, and ends at the moment when the Charge Point irrevocably leaves this state.
StringCase Sensitive String. Only printable ASCII allowed. All strings in messages and enumerations are case sensitive, unless explicitly stated otherwise.

+ +# 3. Introduction + +This is the specification for OCPP version 1.6. + +OCPP is a standard open protocol for communication between Charge Points and a Central System and is designed to accommodate any type of charging technique. + +OCPP 1.6 introduces new features to accommodate the market: Smart Charging, OCPP using JSON over Web sockets, better diagnostics possibilities (Reason), more Charge Point Statuses and TriggerMessage. OCPP 1.6 is based on OCPP 1.5, with some new features and a lot of textual improvements, clarifications and fixes for all known ambiguities. Due to improvements and new features, OCPP 1.6 is not backward compatible with OCPP 1.5. + +For a full list of changes, see: New in OCPP 1.6. + +Some basic concepts are explained in the sections below in this introductory chapter. The chapters: Operations Initiated by Charge Point and Operations Initiated by Central System describe the operations supported by the protocol. The exact messages and their parameters are detailed in the chapter: Messages and data types are described in chapter: Types. Defined configuration keys are described in the chapter: Standard Configuration Key Names & Values. + +# 3.1. Edition 2 + +This document is OCPP 1.6 edition 2. This document still describes the same protocol: OCPP 1.6, only the documentation is improved. On message level there are no changes compared to the original release of OCPP 1.6 of October 2015. All known errata (previously published in a separate document) have been merged into this document, making it easier for the implementers to work with the specification. When there is doubt about the way OCPP 1.6 should be implemented, this document over rules the original document. + +# 3.2. Document structure + +With the introduction of OCPP 1.6, there are two different flavours of OCPP; next to the SOAP based implementations, there is the possibility to use the much more compact JSON alternative. To avoid confusion in communication on the type of implementation we recommend using the distinct suffixes -J and -S to indicate JSON or SOAP. In generic terms this would be OCPP-J for JSON and OCPP-S for SOAP. + +To support the different flavours, the OCPP standard is divided in multiple documents. The base document (the one you are reading now) contains the technical protocol specification. The technical protocol specification must be used with one of the transport protocol specifications. the OCPP SOAP Specification contains the implementation specification needed to make a OCPP-S implementation. For OCPP-J, the OCPP JSON Specification must be used. + +For improved interoperability between the Central Systems and Charge Points, it is advised to meet the requirements stated in the OCPP 1.6 Compliance testing documentation. + +# 3.3. Feature Profiles + +This section is normative. + +In OCPP 1.6 features and associated messages are grouped in profiles. Depending on the required functionality, implementers can choose to implement one or more of the following profiles. + +
PROFILE NAMEDESCRIPTION
CoreBasic Charge Point functionality comparable with OCPP 1.5 [OCPP1.5] without support for firmware updates, local authorization list management and reservations.
Firmware ManagementSupport for firmware update management and diagnostic log file download.
Local Auth List ManagementFeatures to manage the local authorization list in Charge Points.
ReservationSupport for reservation of a Charge Point.
Smart ChargingSupport for basic Smart Charging, for instance using control pilot.
Remote TriggerSupport for remote triggering of Charge Point initiated messages
+ +These profiles can be used by a customer to determine if a OCPP 1.6 product has the required functionality for their business case. Compliance testing will test per profile if a product is compliant with the OCPP 1.6 specification. + +Implementation of the Core profile is required. Other profiles are optional. + +When the profiles Core, Firmware Management, Local Auth List Management and Reservation are implemented, all functions originating from OCPP 1.5 [OCPP1.5] are covered. + +The grouping of all messages in their profiles can be found in the table below. + +

+ +The support for the specific feature profiles is reported by the SupportedFeatureProfiles configuration key. + +# 3.4. General views of operation + +This section is informative. + +The following figures describe the general views of the operations between Charge Point and Central System for two cases: + +1. a Charge Point requesting authentication of a card and sending charge transaction status, +2. Central System requesting a Charge Point to update its firmware. + +The arrow labels in the following figures indicate the PDUs exchanged during the invocations of the operations. These PDUs are defined in detail in the Messages section. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/e37d96ecee2c77c86d69e737a481ca20ab302fa4e57dfb0bace9ed60f17d7be3.jpg) +Figure 1. Sequence Diagram: Example of starting and stopping a transaction + +When a Charge Point needs to charge an electric vehicle, it needs to authenticate the user first before the charging can be started. If the user is authorized the Charge Point informs the Central System that it has started with charging. + +When a user wishes to unplug the electric vehicle from the Charge Point, the Charge Point needs to verify that the user is either the one that initiated the charging or that the user is in the same group and thus allowed to terminate the charging. Once authorized, the Charge Point informs the Central System that the charging has been stopped. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/3c5465b43f53bf0f4f9e65e6d002d8187dea62b3e15bba88f3b5e6897c47acac.jpg) + +A Charge Point MUST NOT send an Authorization.req before stopping a transaction if the presented idTag is the same as the idTag presented to start the transaction. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/799e6faf68efef8a2b42d54baf656867e9b6f68d9ab7368a0312066815fcbea3.jpg) +Figure 2. Sequence Diagram: Example of a firmware update + +When a Charge Point needs to be updated with new firmware, the Central System informs the Charge Point of the time at which the Charge Point can start downloading the new firmware. The Charge Point SHALL notify the Central System after each step as it downloads and installs the new firmware. + +# 3.5. Local Authorization & Offline Behavior + +This section is normative. + +In the event of unavailability of the communications or even of the Central System, the Charge Point is designed to operate stand-alone. In that situation, the Charge Point is said to be offline. + +To improve the experience for users, a Charge Point MAY support local authorization of identifiers, using an Authorization Cache and/or a Local Authorization List. + +This allows (a) authorization of a user when offline, and (b) faster (apparent) authorization response time when communication between Charge Point and Central System is slow. + +The LocalAuthorizationOffline configuration key controls whether a Charge Point will authorize a user when offline using the Authorization Cache and/or the Local Authorization List. + +The LocalPreauthorize configuration key controls whether a Charge Point will use the Authorization Cache and/or the Local Authorization List to start a transaction without waiting for an authorization response from the Central System. + +A Charge Point MAY support the (automatic) authorization of any presented identifier when offline, to avoid refusal of charging to bona-fide users that cannot be explicitly authorized by Local Authorization List/Authorization Cache entries. This functionality is explained in more detail in Unknown Offline Authorization. + +# 3.5.1. Authorization Cache + +A Charge Point MAY implement an Authorization Cache that autonomously maintains a record of previously presented identifiers that have been successfully authorized by the Central System. (Successfully meaning: a response received on a message containing an idTag) + +If implemented, the Authorization Cache SHOULD conform to the following semantics: + +- The Cache contains all the latest received identifiers (i.e. valid and NOT-valid). +- The Cache is updated using all received IdTagInfo (from Authorization.conf, StartTransaction.conf and StopTransaction.conf) +- When the validity of a Cache entry expires, it SHALL be changed to expired in the Cache. +- When an IdTagInfo is received for an identifier in the Cache, it SHALL be updated. +- If new identifier authorization data is received and the Authorization Cache is full, the Charge Point SHALL remove any NOT-valid entries, and then, if necessary, the oldest valid entries to make space for the new entry. +- Cache values SHOULD be stored in non-volatile memory, and SHOULD be persisted across reboots and power outages. +- When an identifier is presented that is stored in the cache as NOT-valid, and the Charge Point is online: an Authorization.req SHOULD be sent to the central System to check the current state of the identifier. + +Operation of the Authorization Cache, when present, is reported (and controlled, where possible) by the AuthorizationCacheEnabled configuration key. + +# 3.5.2. Local Authorization List + +The Local Authorization List is a list of identifiers that can be synchronized with the Central System. + +The list contains the authorization status of all (or a selection of) identifiers and the authorization status/expiration date. + +Identifiers in the Local Authorization list can be marked as valid, expired, (temporarily) blocked, or blacklisted, corresponding to IdTagInfo status values Accepted/ConcurrentTx, Expired,Blocked, and Invalid, respectively. + +These values may be used to provide more fine grained information to users (e.g. by display message) during local authorization. + +The Local Authorization List SHOULD be maintained by the Charge Point in non-volatile memory, and SHOULD be persisted across reboots and power outages. + +A Charge Point that supports Local Authorization List SHOULD implement the configuration key: LocalAuthListMaxLength This gives the Central System a way to know the the maximum possible number of Local Authorization List elements in a Charge Point + +The Charge Point indicates whether the Local Authorization List is supported by the presence or absence of the LocalAuthListManagement element in the value of the SupportedFeatureProfiles configuration key. + +Whether the Local Authorization List is enabled is reported and controlled by the LocalAuthListEnabled configuration key. + +The Central System can synchronize this list by either (1) sending a complete list of identifiers to replace the Local Authorization List or (2) by sending a list of changes (add, update, delete) to apply to the Local Authorization List. The operations to support this are Get Local List Version and Send Local List. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/4006fec2a6e910c77348bc5a4dd750c8ba6ee374152f214edcde7cdcc8316130.jpg) +Figure 3.

When this happens the Charge Point SHALL inform the Central System by sending a StatusNotification with ConnectorId set to 0, andErrorCode set to 'LocalListConflict'. + +# 3.5.3. Relation between Authorization Cache and Local Authorization List + +The Authorization Cache and Local Authorization List are distinct logical data structures. Identifiers known in the Local Authorization List SHALL NOT be added to the Authorization Cache. + +Where both Authorization Cache and Local Authorization List are supported, a Charge Point SHALL treat Local Authorization List entries as having priority over Authorization Cache entries for the same identifiers. + +# 3.5.4. Unknown Offline Authorization + +When offline, a Charge Point MAY allow automatic authorization of any "unknown" identifiers that cannot be explicitly authorized by Local Authorization List or Authorization Cache entries. Identifiers that are present in a Local Authorization List that have a status other than "Accepted" (Invalid, Restricted, Expired) MUST be rejected. Identifiers that were valid but are apparently expired due to passage of time MUST also be rejected. + +Operation of the Unknown Offline Authorization capability, when supported, is reported (and controlled, where possible) by the AllowOfflineTxForUnknownId configuration key. + +When connection to the Central Server is restored, the Charge Point SHALL send a Start Transaction request for any transaction that was authorized offline, as required by transaction-related message handling. When the authorization status in the StartTransaction.conf is not Accepted, and the transaction is still ongoing, the Charge Point SHOULD: + +- when StopTransactionOnInvalidId is set to true: stop the transaction normally as stated in Stop Transaction. The Reason field in the Stop Transaction request should be set to DeAuthorized. If the Charge Point has the possibility to lock the Charging Cable, it SHOULD keep the Charging Cable locked until the owner presents his identifier. +- when StopTransactionOnInvalidId is set to false: only stop energy delivery to the vehicle. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/f451a07a3c06cdeabfe4aea4ca5fbf05adaeb95e5f3781c5a4d58723247e070a.jpg) + +In the case of an invalid identifier, an operator MAY choose to charge the EV with a minimum amount of energy so the EV is able to drive away. This amount is controlled by the optional configuration key: MaxEnergyOnInvalidId. + +# 3.6. Transaction in relation to Energy Transfer Period + +This section is informative. + +The Energy Transfer Period is a period of time during which energy is transferred between the EV and the EVSE. There MAY be multiple Energy Transfer Periods during a Transaction. + +Multiple Energy Transfer Periods can be separated by either: + +- an EVSE-initiated supense of transfer during which de EVSE does not offer energy transfer +- an EV-initiated suspense of transfer during which the EV remains electrically connected to the EVSE +- an EV-initiated suspense of transfer during which the EV is not electrically connected to the EVSE. + +A Central System MAY deduce the start and end of an Energy Transfer Period from: the MeterValues that are sent during the Transaction, the status notifications: Charging, SuspendedEV and/or SuspendedEVSE. etc. Central System implementations need to take into account factors such as: Some EVs don't go to state SuspendedEV: they might continue to trickle charge. Some Charge Point don't even have a electrical meter. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/764216b28b8d3dd1fba393e38d4b5afff05c7b476c5cea4f83d19d5e4e516cba.jpg) +Figure 5. OCPP Charging Session and transaction definition + +# 3.7. Transaction-related messages + +This section is normative. + +The Charge Point SHOULD deliver transaction-related messages to the Central System in chronological order as soon as possible. Transaction-related messages are StartTransaction.req, StopTransaction.req and periodic or clock-aligned MeterValues.req messages. + +When offline, the Charge Point MUST queue any transaction-related messages that it would have sent to the Central System if the Charge Point had been online. + +In the event that a Charge Point has transaction-related messages queued to be sent to the Central System, new messages that are not transaction-related MAY be delivered immediately without waiting for the queue to be emptied. It is therefore allowed to send, for example, an Authorization request or a Notifications request before the transaction-related message queue has been emptied, so that customers are not kept waiting and urgent notifications are not delayed. + +The delivery of new transaction-related messages SHALL wait until the queue has been emptied. This is to ensure that transaction-related messages are always delivered in chronological order. + +When the Central System receives a transaction-related message that was queued on the Charge Point for some time, the Central System will not be aware that this is a historical message, other than by inference given that the various timestamps are significantly in the past. It SHOULD process such a message as any other. + +# 3.7.1. Error responses to transaction-related messages + +It is permissible for the Charge Point to skip a transaction-related message if and only if the Central System repeatedly reports a `failure to process the message'. Such a stipulation is necessary, because otherwise the requirement to deliver every transaction-related message in chronological order would entail that the Charge Point cannot deliver any transaction-related messages to the Central System after a software bug causes the Central System not to acknowledge one of the Charge Point's transaction-related messages. + +What kind of response, or failure to respond, constitutes a `failure to process the message' is defined in the documents OCPP JSON Specification and OCPP SOAP Specification. + +The number of times and the interval with which the Charge Point should retry such failed transaction-related messages MAY be configured using the TransactionMessageAttempts and + +TransactionMessageRetryInterval configuration keys. + +When the Charge Point encounters a first failure to deliver a certain transaction-related message, it SHOULD send this message again as long as it keeps resulting in a failure to process the message and it has not yet encountered as many failures to process the message for this message as specified in its + +TransactionMessageAttempts configuration key. Before every retransmission, it SHOULD wait as many seconds as specified in its TransactionMessageRetryInterval key, multiplied by the number of preceding transmissions of this same message. + +As an example, consider a Charge Point that has the value "3" for the TransactionMessageAttempts configuration key and the value "60" for the TransactionMessageRetryInterval configuration key. It sends a StopTransaction message and detects a failure to process the message in the Central System. The Charge Point + +SHALL wait for 60 seconds, and resend the message. In the case when there is a second failure, the Charge Point SHALL wait for 120 seconds, before resending the message. If this final attempt fails, the Charge Point SHOULD discard the message and continue with the next transaction-related message, if there is any. + +# 3.8. Connector numbering + +This section is normative. + +To enable Central System to be able to address all the connectors of a Charge Point, ConnectorIds MUST always be numbered in the same way. + +Connectors numbering (Connectorlds) MUST be as follows: + +- ID of the first connector MUST be 1 + Additional connectors MUST be sequentially numbered (no numbers may be skipped) +- ConnectorIds MUST never be higher than the total number of connectors of a Charge Point +- For operations initiated by the Central System, ConnectorId 0 is reserved for addressing the entire Charge Point. +- For operations initiated by the Charge Point (when reporting), Connectorld 0 is reserved for the Charge Point main controller. + +Example: A Charge Point with 3 connectors: All connectors MUST be numbered with the IDs: 1, 2 and 3. It is advisable to number the connectors of a Charge Point in a logical way: from left to right, top to bottom incrementing. + +# 3.9. ID Tokens + +This section is normative. + +In most cases, IdToken data acquired via local token reader hardware is usually a (4 or 7 byte) UID value of a physical RFID card, typically represented as 8/14 hexadecimal digit characters. + +However, IdTokens sent to Charge Points by Central Systems for remotely initiated charging sessions may commonly be (single use) virtual transaction authorization codes, or virtual RFID tokens that deliberately use a non-standard UID format to avoid possible conflict with real UID values. + +Also, IdToken data used as ParentIds may often use a shared central account identifier for the ParentId, instead of a UID of the first/master RFID card of an account. + +Therefore, message data elements of the IdToken class (including ParentId) MAY contain any data, subject to the constraints of the data-type (CiString20Type), that is meaningful to a Central System (e.g. for the purpose of identifying the initiator of charging activity), and Charge Points MUST NOT make any presumptions as to the format or content of such data (e.g. by assuming that it is a UID-like value that must be hex characters only and/or an even number of digits). + +To promote interoperability, based on common practice to date in the case of IdToken data representing physical ISO 14443 compatible RFID card UIDs, it is RECOMMENDED that such UIDs be represented as hex representations of the UID bytes. According to ISO14443-3, byte 0 should come first in the hex string. + +# 3.10. Parent idTag + +This section is normative. + +A Central System has the ability to treat a set of identity tokens as a "group", thereby allowing any one token in the group to start a transaction and for the same token, or another token in the same group, to stop the transaction. This supports the common use-cases of families or businesses with multiple drivers using one or more shared electric vehicles on a single recharging contract account. + +Tokens (idTags) are grouped for authorization purposes by specifying a common group identifier in the optional ParentId element in IdTagInfo: two idTags are considered to be in the same group if their ParentId Tags match. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/a6d2208bf403f42d599dd8fc5e2241172027f24378ac9588b9e2d6b442b87970.jpg) + +Even though the ParentId has the same nominal data type (IdToken) as an idTag, the value of this element may not be in the common format of IdTokens and/or may not represent an actual valid IdToken (e.g. it may be a common shared "account number"): therefore, the ParentId value SHOULD NOT be used for comparison against a presented Token value (unless it also occurs as an idTag value). + +# 3.11. Reservations + +This section is informative. + +Reservation of a Charge Point is possible using the Reserve Now operation. This operation reserves the Charge Point until a certain expiry time for a specific idTag. A parent idTag may be included in the reservation to support 'group' reservations. It is possible to reserve a specific connector on a Charge Point or to reserve any connector on a Charge Point. A reservation is released when the reserved idTag is used on the reserved connector (when specified) or on any connector (when unspecified) or when the expiry time is reached or when the reservation is explicitly canceled. + +# 3.12. Vendor-specific data transfer + +This section is informative. + +The mechanism of vendor-specific data transfer allows for the exchange of data or messages not standardized in OCPP. As such, it offers a framework within OCPP for experimental functionality that may find its way into future OCPP versions. Experimenting can be done without creating new (possibly incompatible) OCPP dialects. Secondly, it offers a possibility to implement additional functionality agreed upon between specific Central System and Charge Point vendors. + +The operation Vendor Specific Data MAY be initiated either by the Central System or by the Charge Point. + +Please use with extreme caution and only for optional functionality, since it will impact your compatibility with other systems that do not make use of this option. We recommend mentioning the usage explicitly in your documentation and/or communication. Please consider consulting the Open Charge Alliance before turning to this option to add functionality. + +# 3.13. Smart Charging + +This section is normative. + +With Smart Charging a Central System gains the ability to influence the charging power or current of a specific EV, or the total allowed energy consumption on an entire Charge Point / a group of Charge Points, for instance, based on a grid connection, energy availability on the gird or the wiring of a building. Influencing the charge power or current is based on energy transfer limits at specific points in time. Those limits are combined in a Charging Profile. + +# 3.13.1. Charging profile purposes + +A charging profile consists of a charging schedule, which is basically a list of time intervals with their maximum charge power or current, and some values to specify the time period and recurrence of the schedule. + +There are three different types of charging profiles, depending on their purpose: + +- ChargePointMaxProfile + +In load balancing scenarios, the Charge Point has one or more local charging profiles that limit the power or current to be shared by all connectors of the Charge Point. The Central System SHALL configure such a profile with ChargingProfilePurpose set to "ChargePointMaxProfile". ChargePointMaxProfile can only be set at Charge Point ConnectorId 0. + +- TxDefaultProfile + +Default schedules for new transactions MAY be used to impose charging policies. An example could be a policy that prevents charging during the day. For schedules of this purpose, ChargingProfilePurpose SHALL be set to TxDefaultProfile. + +If TxDefaultProfile is set to ConnectorId 0, the TxDefaultProfile is applicable to all Connectors. + +If Connectorld is set $>0$ , it only applies to that specific connector. + +In the event a TxDefaultProfile for connector 0 is installed, and the Central System sends a new profile with ConnectorId $>0$ , the TxDefaultProfile SHALL be replaced only for that specific connector. + +- TxProfile + +If a transaction-specific profile with purpose TxProfile is present, it SHALL overrule the default charging profile with purpose TxDefaultProfile for the duration of the current transaction only. After the transaction is stopped, the profile SHOULD be deleted. If there is no transaction active on the connector specified in a charging profile of type TxProfile, then the Charge Point SHALL discard it and return an error status in SetChargingProfile.conf. + +The final schedule constraints that apply to a transaction are determined by merging the profiles with purposes ChargePointMaxProfile with the profile TxProfile or the TxDefaultProfile in case no profile of purpose TxProfile is provided. TxProfile SHALL only be set at Charge Point ConnectorId >0. + +# 3.13.2. Stacking charging profiles + +It is allowed to stack charging profiles of the same charging profile purpose in order to describe complex calendars. For example, one can define a charging profile of purpose TxDefaultProfile with a duration and recurrence of one week that allows full power or current charging on weekdays from 23:00h to 06:00h and from 00:00h to 24:00h in weekends and reduced power or current charging at other times. On top of that, one can define other TxDefaultProfiles that define exception to this rule, for example for holidays. + +Precedence of charging profiles is determined by the value of their StackLevel parameter. At any point in time the prevailing charging profile SHALL be the charging profile with the highest stackLevel among the profiles that are valid at that point in time, as determined by their validFrom and validTo parameters. + +To avoid conflicts, the existence of multiple Charging Profiles with the same stackLevel and Purposes in a Charge Point is not allowed. Whenever a Charge Point receives a Charging Profile with a stackLevel and Purpose that already exists in the Charge Point, the Charge Point SHALL replace the existing profile. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/4322e08d1c659500b0b633a7bc5b207e81b20bd7109fd5109830b034be3184e7.jpg) + +In the case an updated charging profile (with the same stackLevel and purpose) is sent with a validFromDateTime in the future, the Charge Point SHALL replace the installed profile and SHALL revert to default behavior until validFrom is reached. It is RECOMMENDED to provide a start time in the past to prevent gaps. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/58cf6f27e87593c20bd51f1c9f1cf83af7cde34700fc512ced53a1e2231b247b.jpg) + +If you use Stacking without a duration, on the highest stack level, the Charge Point will never fall back to a lower stack level profile. + +# 3.13.3. Combining charging profile purposes + +The Composite Schedule that will guide the charging level is a combination of the prevailing Charging Profiles of the different chargingProfilePurposes. + +This Composite Schedule is calculated by taking the minimum value for each time interval. Note that time intervals do not have to be of fixed length, nor do they have to be the same for every charging profile purpose. This means that a resulting Composite Schedule MAY contain intervals of different lengths. + +At any point in time, the available power or current in the Composite Schedule, which is the result of merging the schedules of charging profiles ChargePointMaxProfile and TxDefaultProfile (or TxProfile), SHALL be less than or equal to lowest value of available power or current in any of the merged schedules. + +In the case the Charge Point is equipped with more than one Connector, the limit value of ChargePointMaxProfile is the limit for all connectors combined. The combined energy flow of all connectors SHALL NOT be greater then the limit set by ChargePointMaxProfile. + +# 3.13.4. Smart Charging Use Cases + +This section is informative. + +There may be many different uses for smart charging. The following three typical kinds of smart charging will be used to illustrate the possible behavior of smart charging: + +- Load balancing + Central smart charging +- Local smart charging + +There are more complex use cases possible in which two or more of the above use cases are combined into one more complex system. + +# Load Balancing + +This section is informative. + +The Load Balancing use case is about internal load balancing within the Charge Point, the Charge Point controls the charging schedule per connector. The Charge Point is configured with a fixed limit, for example the maximum current of the connection to the grid. + +The optional charging schedule field minChargingRate may be used by the Charge Point to optimize the power distribution between the connectors. The parameter informs the Charge Point that charging below minChargingRate is inefficient, giving the possibility to select another balancing strategy. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/eb604befbf6b4a78994bf6e8fd55693f6a26def3eeaaa97799b4bfe303b07023.jpg) +Figure 6. Load balancing Smart Charging topology + +# Central Smart Charging + +This section is informative. + +With Central smart charging the constraints on the charging schedule, per transaction, are determined by the Central System.

Central Smart Charging topology + +Central smart charging assumes that charge limits are controlled by the Central System. The Central System receives a capacity forecast from the grid operator (DSO) or another source in one form or another and calculates charging schedules for some or all charging transactions, details of which are out of scope of this specification. + +The Central System imposes charging limits on connectors. In response to a StartTransaction.req PDU The Central System may choose to set charging limits to the transaction using the TxProfile + +Central Smart Charging can be done with a Control Pilot signal, albeit with some limitations, because an EV cannot communicate its charging via the Control Pilot signal. In analogy to the Local Smart Charging use case, a connector can execute a charging schedule by the Control Pilot signal. This is illustrated in the Figure below: + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/cb7846ea1ad3e49a788611b59a00e5aebf88c2b541961f701a72d11a4cf0b878.jpg) +Figure 8. Sequence Diagram: Central Smart Charging + +Explanation for the above figure: + +- After authorization the connector will set a maximum current to use via the Control Pilot signal. This limit is based on a (default) charging profile that the connector had previously received from the Central System.

Optionally, at any point in time the Central System may send a new charging profile for the connector that shall be used as a limit schedule for the EV. + +# Local Smart Charging + +The Local Smart Charging use case describes a use case in which smart charging enabled Charge Points have charging limits controlled locally by a Local Controller, not the Central System. The use case for local smart charging is about limiting the amount of power that can be used by a group of Charge Points, to a certain maximum. A typical use would be a number of Charge Points in a parking garage where the rating of the connection to the grid is less than the sum the ratings of the Charge Points. Another application might be that the Local Controller receives information about the availability of power from a DSO or a local smart grid node. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/8f2c9c1aaa3786dcd41e9186b88b1d4982df52654d7de89153c85414ffb26ec9.jpg) +Figure 9. Local Smart Charging topology + +Local smart charging assumes the existence of a Local Controller to control a group of Charge Points. The Local Controller is a logical component. It may be implemented either as a separate physical component or as part of a 'master' Charge Point controlling a number of other Charge Points. The Local Control implements the OCPP protocol and is a proxy for the group members' OCPP messages, and may or may not have any connectors of its own. + +In the case of local smart charging the Local Controller imposes charging limits on a Charge Point. These limits may be changed dynamically during the charging process in order to keep the power consumption of the group of Charge Points within the group limits. The group limits may be pre-configured in the Local Controller or may have been configured by the Central System. + +The optional charging schedule field minChargingRate may be used by the Local Controller to optimize the power distribution between the connectors. The parameter informs the Local Controller that charging below minChargingRate is inefficient, giving the possibility to select another balancing strategy. + +The following diagram illustrates the sequence of messages to set charging limits on Charge Points in a Local Smart Charging group. These limits can either be pre-configured in the Local Controller in one way or another, or they can be set by the Central System. The Local Controller contains the logic to distribute this capacity among the connected connectors by adjusting their limits as needed. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/0df490989515281168997f84262a8d00682d70210ec83e4fa9be5dbc9b9513e0.jpg) +Figure 10.

Discovery of Charge Point Capabilities + +This section is normative. + +The smart charging options defined can be used in extensive ways. Because of the possible limitations and differences in capabilities between Charge Points, the Central System needs to be able to discover the Charge Point specific capabilities.

In OCPP, this is called "sampled meter data", as the exact frequency and time of readings is not very significant, as long as it is "frequent enough". "Sampled meter data" can be configured with the following configuration keys: + +- MeterValuesSampledData +- MeterValuesSampledDataMaxLength +- MeterValueSampleInterval +- StopTxnSampledData +- StopTxnSampledDataMaxLength + +MeterValueSampleInterval is the time (in seconds) between sampling of metering (or other) data, intended to be transmitted by "MeterValues" PDUs.

Sequence Diagram: Trigger Message + +During normal operation, the Charge Point informs the Central System of its state and any relevant occurrences. If there is nothing to report the Charge Point will send at least a heartBeat at a predefined interval. Under normal circumstances this is just fine, but what if the Central System has (whatever) reason to doubt the last known state? What can a Central System do if a firmware update is in progress and the last status notification it received about it was much longer ago than could reasonably be expected? The same can be asked for the progress of a diagnostics request. The problem in these situations is not that the information needed isn't covered by existing messages, the problem is strictly a timing issue. The Charge Point has the information, but has no way of knowing that the Central System would like an update. + +The TriggerMessage.req makes it possible for the Central System, to request the Charge Point, to send Charge + +Point-initiated messages. In the request the Central System indicates which message it wishes to receive. For every such requested message the Central System MAY optionally indicate to which connector this request applies. The requested message is leading: if the specified connectorid is not relevant to the message, it should be ignored. In such cases the requested message should still be sent. + +Inversely, if the connectorId is relevant but absent, this should be interpreted as "for all allowed connectorld values". For example, a request for a statusNotification for connectorld 0 is a request for the status of the Charge Point. A request for a statusNotification without connectorld is a request for multiple statusNotifications: the notification for the Charge Point itself and a notification for each of its connectors. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-10-28/7b0547c1-0a53-4904-8916-f3302ac3172e/647ead90a519f3d91bc46c4b35900ef8e844bab9aac9f4a0a2f75fbc987753d3.jpg) +Figure 39. Sequence Diagram: Trigger Message StatusNotification Example + +The Charge Point SHALL first send the TriggerMessage response, before sending the requested message. In the TriggerMessage.conf the Charge Point SHALL indicate whether it will send it or not, by returning ACCEPTED or REJECTED. It is up to the Charge Point if it accepts or rejects the request to send. If the requested message is unknown or not implemented the Charge Point SHALL return NOTIMPLEMENTED. + +Messages that the Charge Point marks as accepted SHOULD be sent. The situation could occur that, between accepting the request and actually sending the requested message, that same message gets sent because of normal operations. In such cases the message just sent MAY be considered as complying with the request. + +The TriggerMessage mechanism is not intended to retrieve historic data. The messages it triggers should only give current information. A MeterValues.req message triggered in this way for instance SHALL return the most recent measurements for all measurands configured in configuration key MeterValuesSampledData. + +StartTransaction and StopTransaction have been left out of this mechanism because they are not state related, but by their nature describe a transition. + +# 5.18.

This is a last resort solution for a not correctly functioning Charge Point, by sending a "hard" reset, (queued) information might get lost.
SoftStop ongoing transactions gracefully and sending StopTransaction.req for every ongoing transaction. It should then restart the application software (if possible, otherwise restart the processor/controller).

Page 20, section 3.13.1: Effect of updating or deleting TxDefaultProfile during a transaction not defined + +Added in errata sheet v4.0 + +It was not clear that a new TxDefaultProfile not only applies to running transactions with a TxDefaultProfile, but also to running transactions without a ChargingProfile. Furthermore, removing a TxDefaultProfile will cause running transactions to continue without a TxDefaultProfile. + +To clarify this best, two additional paragraphs are needed. + +
PageSectionAdditional text
203.13.1When an new or updated TxDefaultProfile is received and a transaction is ongoing that is not using a ChargingProfile or using the current TxDefaultProfile, the transaction SHALL continue, but switch to using the new or updated TxDefaultProfile. When TxDefaultProfile is removed, then running transactions, that started with that profile, SHALL continue without a TxDefaultProfile.
545.16.3When the ongoing transaction is not using a ChargingProfile or using the TxDefaultProfile, and a new or updated TxDefaultProfile is received, the transaction SHALL continue, but switch to using the new or updated TxDefaultProfile.
+ +# 3.9. Page 29, section: 3.1.6: Missing advice to send meter register value if available + +Added in errata sheet v4.0 + +When a Charge Point has a meter which allows the value of Meter Register (counter) to be read. It is seen as best to send this value instead of start every transaction at 0. + +
Additional textIf a Charge Point contains a Meter that has a register that can be read (instead of counting pulses or some other way of measuring the amount of energy etc.) It is RECOMMENDED to send this register value in every MeterValue send instead of starting at 0 for every transaction.
+ +# 3.10. Page 33, new Chapter about time notations + +In addition to "3.13 Time Zones" to following should have been added about time notations: + +
New text3.14 Time notations +Implementations MUST use ISO 8601 date time notation. Message receivers must be able to handle fractional seconds and time zone offsets (another implementation might use them). Message senders MAY save data usage by omitting insignificant fractions of seconds.
+ +# 3.11. Page 35, section: 4.2: Boot Notification: Note on behaviour while not accepted by Central system + +
Old textWhile not yet accepted by the Central System, the Charge Point may allow locally authorized transactions if it is configured to do so, as described in Local Authorization & Offline Behaviour. Parties who want to implement this behaviour must realize that it is uncertain if those transactions can ever be delivered to the Central System.
New textA Charge Point Operator MAY choose to configure a Charge Point to accept transactions before the Charge Point is accepted by a Central System. Parties who want to choose to implement this behavior should realize that it is uncertain if those transactions can ever be delivered to the Central System. +After a restart (for instance due to a remote reset command, power outage, firmware update, software error etc.) the Charge Point MUST again contact the Central System and SHALL send a BootNotification request. If the Charge Point fails to receive a BootNotification.conf from the Central System, and has no in-built non-volatile real-time clock hardware that has been correctly preset, the Charge Point may not have a valid date / time setting, making it impossible to later determine the date / time of transactions. +It might also be the case (e.g. due to configuration error) that the Central System indicates a status other than Accepted for an extended period of time, or indefinitely. +It is usually advisable to deny all charging services at a Charge Point if the Charge Point has never before been Accepted by the Central System (using the current connection settings, URL, etc.) since users cannot be authenticated and running transactions could conflict with provisioning processes.

WWatts (power).Watts (power). This is the TOTAL allowed charging power.

The "Number of Phases" is the numberPhases from the ChargingSchedulePeriod. It is usually more convenient to use this for DC charging. Note that if numberPhases in a ChargingSchedulePeriod is absent, 3 SHALL be assumed.
AAmperes (current).Amperes (current). The amount of Ampere per phase, not the sum of all phases. It is usually more convenient to use this for AC charging.

DescriptionThe maximum amount of meter values that this Charge Point can report in the transactionData field of a StopTransaction.req. When the amount of meter values collected for a transaction exceeds: StopTransactionMaxMeterValues, the Charge Point MAY drop intermediate meter values, to prevent running out of memory, or being unable to send the StopTransaction.req (overrunning the transmit buffer size). The Start and Stop meter values SHALL never be dropped.
When the Charge Point needs to store more intermediate values than: StopTransactionMaxMeterValues, it is RECOMMENDED not to start dropping messages from the start, or stop storing new values. It is better to drop intermediate messages first (1st message, 3th message, 5th message etc.), or uses a smart algorithm, for example remove duplicate values first. etc.

v1.0 Release2019-12-04Release of the OCPP-J errata sheet
+ +# 1. Scope + +This document contains errata on the OCPP 1.6-J specification (JSON) and JSON-Schema files. + +# 1.1. JSON Schema files + +With the release of this version of the erratasheet (2025-04) also a OCPP 1.6 JSON Schema file was updated. + +Version information has been added to all the files: ID field. The updated StopTransaction.req JSON Schema file for this version is marked with: "urn:OCPP:1.6:2025:04" + +# 1.2. Terminology and Conventions + +Underlined: when needed to clarify differences, they might be underlined. + +# 2. Major errata + +Problems with the content/definition of the messages, class and enumerations of the protocol. + +# 2.1. (2025-04) - MeterValues.json and StopTransaction.json incorrect spelling of Celsius V2 + +Note: This erratum supersedes erratum: MeterValues.json and StopTransaction.json incorrect spelling of Celsius + +There are several issues with the original erratum that needs to be revised. + +The erratum advises Central System implementers to update their own JSON schemas to also allow the correct spelling. This brings risks, as the erratum is easily missed and the JSON schema's will be used as available on the website. + +In addition, the erratum advises the Charge Point implementers to update their messages to use the corrected spelling. This poses significant risk as this will cause interoperability issues with all Central Systems that have not updated their JSON schemas. + +Finally, while the erratum mentions that the JSON schemas will not be fixed, the MeterValues.req JSON schema was updated. Unfortunately the StopTransaction.req JSON schema was missed. Updating the JSON schemas so they contain both spellings is the correct decision, because the main purpose of the JSON schemas is that they are being used for JSON Schema validation. In this case we always want to allow both spellings, to maximize interoperability. The secondary purpose is generating the message data model from them, but even in that case the Charge Point implementer makes an active decision on which unit of measure to send. Both spellings would be a valid choice, but when a Charge Point implementer reads this erratum, it recommends to use the not corrected version of the spelling; Celcius, to maximize interoperability. + +# Summary: + +1. The JSON schema StopTransaction.req is updated to also include the corrected spelling Celsius. +2. Charge Point implementers are advised to remain using the not corrected version of the spelling Celcius. + +3. Central System implementers are advised to use the updated JSON schema for their JSON schema validation and accept both spellings; Celsius and Celcius. + +# 2.2. MeterValues.json and StopTransaction.json incorrect spelling of Celsius + +Note: This erratum has been superseded by erratum: (2025-04) - MeterValues.json and StopTransaction.json incorrect spelling of Celsius V2 + +The OCPP 1.6 JSON schema message definitions set, as originally published, contains a typo that renders it inconsistent with both the written OCPP 1.6 specification and the SOAP/XML Schema/WSDLs schema definitions. + +In the MeterValues and StopTransaction message structure (in MeterValues.json and StopTransaction.json), the definition of Celsius as a unit has been misspelled as: "Celcius". + +We advise implementers of an OCPP 1.6 JSON Central System to add the correct spelling (Celsius) to the enumeration. This way your implementation will support both the correct and the incorrect spellings. Somebody implementing a OCPP 1.6 JSON Charge Point, and using the object generated by the WSDL files to serialize JSON might send the correct spelling to a Central System. + +We advise the implementers of OCPP 1.6 JSON Charge Points to correct the spelling mistake. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-11-07/866f1405-2837-49bc-b083-2f778879e529/bc7d36421951114d841ac0b47cd3954cac0ff833685b1cc8f39d3e0fe67fb774.jpg) + +This issue will not be fixed in future schema files, Central Systems need to support both, and adding both in the Schema could be confusing for Charge Point implementers. + +# 2.3.

+ +# Contents + +# 1. Introduction + +# 1.1. Purpose of this document + +The purpose of this document is to give the reader the information required to create a correct interoperable OCPP JSON implementation (OCPP-J). We will try to explain what is mandatory, what is considered good practice and what one should not do, based on our own experience. Undoubtedly misunderstandings or ambiguities will remain but by means of this document we aim to prevent them as much as possible. + +# 1.2. Intended audience + +This document is intended for developers looking to understand and/or implement OCPP JSON in a correct and interoperable way. Rudimentary knowledge of implementing web services on a server or embedded device is assumed. + +# 1.3. OCPP-S and OCPP-J + +With the introduction of OCPP 1.6, there are two different flavours of OCPP; next to the SOAP based implementations, there is the possibility to use the much more compact JSON alternative. To avoid confusion in communication on the type of implementation we recommend using the distinct suffixes -J and -S to indicate JSON or SOAP. In generic terms this would be OCPP-J for JSON and OCPP-S for SOAP. Version specific terminology would be OCPP1.6J or OCPP1.2S. If no suffix is specified for OCPP 1.2 or 1.5 then a SOAP implementation must be assumed. As of release 1.6 this can no longer be implicit and should always be made clear. If a system supports both the JSON and SOAP variant it is considered good practice to label this OCPP1.6JS instead of just OCPP1.6. + +This document describes OCPP-J, for OCPP-S see: [OCPP_IMP_S] + +# 1.4. Conventions + +The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. + +# 1.5.

+ +# 2. Benefits & Issues + +The WebSocket protocol is defined in [RFC6455]. Working implementations of earlier draft WebSocket specifications exist, but OCPP-J implementations SHOULD use the protocol described in [RFC6455]. + +Be aware that WebSocket defines its own message structure on top of TCP. Data sent over aWebSocket, on a TCP level, is wrapped in a WebSocket frame with a header. When using a framework this is completely transparent. When working for an embedded system however, WebSocket libraries may not be available and then one has to frame messages correctly according to [RFC6455] him/herself. + +# 3. Connection + +For the connection between a Charge Point and a Central System using OCPP-J, the Central System acts as a WebSocket server and the Charge Point acts as a WebSocket client. + +# 3.1. Client request + +To set up a connection, the Charge Point initiates a WebSocket connection as described in [RFC6455] section 4, "Opening Handshake". + +OCPP-J imposes extra constraints on the URL and the WebSocket subprotocol, detailed in the following two sections 4.1.1 and 4.1.2. + +# 3.1.1. The connection URL + +To initiate a WebSocket connection, the Charge Point needs a URL ([RFC3986]) to connect to. This URL is henceforth called the "connection URL". This connection URL is specific to a charge point. The charge point's connection URL contains the charge point identity so that the Central System knows which charge point a WebSocket connection belongs to. + +A Central System supporting OCPP-J MUST provide at least one OCPP-J endpoint URL, from which the Charge Point SHOULD derive its connection URL. This OCPP-J endpoint URL can be any URL with a "ws" or "wss" scheme. How the Charge Point obtains an OCPP-J endpoint URL is outside of the scope of this document. + +To derive its connection URL, the Charge Point modifies the OCPP-J endpoint URL by appending to the path first a '/' (U+002F SOLIDUS) and then a string uniquely identifying the Charge Point. This uniquely identifying string has to be percent-encoded as necessary as described in [RFC3986]. + +Example 1: for a charge point with identity “CP001” connecting to a Central System with OCPP-J endpoint URL "ws://centralsystem.example.com/ocpp" this would give the following connection URL: + +ws://centralsystem.example.com/ocpp/CP001 + +Example 2: for a charge point with identity "RDAM 123" connecting to a Central System with OCPP-J endpoint URL "wss://centralsystem.example.com/ocppj" this would give the following URL: + +wss://centralsystem.example.com/ocppj/RDAM%20123 + +# 3.1.2.OCPP version + +The exact OCPP version MUST be specified in the Sec-Websocket-Protocol field. This SHOULD be one of the following values: + +Table 1:OCPP Versions + +
OCPP versionWebSocket subprotocol name
1.2ocpp1.2
1.5ocpp1.5
1.6ocpp1.6
2.0ocpp2.0
+ +The ones for OCPP 1.2, 1.5 and 2.0 are official WebSocket subprotocol name values. They are registered as such with IANA. + +Note that OCPP 1.2 and 1.5 are in the list. Since the JSON over WebSocket solution is independent of the actual message content the solution can be used for older OCPP versions as well. Please keep in mind that in these cases the implementation should preferably also maintain support for the SOAP based solution to be interoperable. + +It is considered good practice to include the OCPP version as part of the OCPP-J endpoint URL string. If you run a web service that can handle multiple protocol versions on the same OCPP-J endpoint URL, this is not necessary of course. + +# 3.1.3. Example of an opening HTTP request + +The following is an example of an opening HTTP request of an OCPP-J connection handshake: + +GET /webServices/ocpp/CP3211 HTTP/1.1 + +Host: some.server.com:33033 + +Upgrade: websocket + +Connection: Upgrade + +Sec-WebSocket-Key: x3JJHMcDL1EzLkh9GBhXDw== + +Sec-WebSocket-Protocol: ocpp1.6, ocpp1.5 + +Sec-WebSocket-Version: 13 + +The bold parts are found as such in every WebSocket handshake request, the other parts are specific to this example. + +In this example, the Central System's OCPP-J endpoint URL is + +"ws://some.server.com:33033/webServices/ocpp". The Charge Point's unique identifier is "CP3211", so the path to request becomes "webServices/ocpp/CP3211". + +With the Sec-WebSocket-Protocol header, the Charge Point indicates here that it can use OCPP1.6J and OCPP1.5J, with a preference for the former. + +The other headers in this example are part of the HTTP and WebSocket protocols and are not relevant to those implementing OCPP-J on top of third-party WebSocket libraries. The roles of these headers are explained in [RFC2616] and [RFC6455]. + +# 3.2. Server response + +Upon receiving the Charge Point's request, the Central System has to finish the handshake with a response as described in [RFC6455]. + +The following OCPP-J-specific conditions apply: + +- If the Central System does not recognize the charge point identifier in the URL path, it SHOULD send an HTTP response with status 404 and abort the WebSocket connection as described in [RFC6455]. +- If the Central System does not agree to using one of the subprotocols offered by the client, it MUST complete the WebSocket handshake with a response without a Sec-WebSocket-Protocol header and then immediately close the WebSocket connection. + +So if the Central System accepts the above example request and agrees to using OCPP 1.6J with the Charge Point, the Central System's response will look as follows: + +HTTP/1.1 101 Switching Protocols + +Upgrade: WebSocket + +Connection: Upgrade + +Sec-WebSocket-Accept: s3pPLMBiTxaQ9kYGzzhZRbK+xOo= + +Sec-WebSocket-Protocol: ocpp1.6 + +The bold parts are found as such in every WebSocket handshake response, the other parts are specific to this example. + +The role of the Sec-WebSocket-Accept header is explained in [RFC6455]. + +The Sec-WebSocket-Protocol header indicates that the server will be using OCPP1.6J on this connection. + +# 3.3. More information + +For those doing their own implementation of the WebSocket handshake, [WS] and [WIKIWS] give more information on the WebSocket protocol. + +# 4. RPC framework + +# 4.1. Introduction + +A WebSocket is a full-duplex connection, simply put a pipe where data goes in and data can come out and without a clear relation between in and out. The WebSocket protocol by itself provides no way to relate messages as requests and responses. To encode these request/response relations we need a small protocol on top of WebSocket. This problem occurs in more use cases of WebSocket so there are existing schemes to solve it. The most widely-used is WAMP (see [WAMP]) but with the current version of that framework handling RPCs symmetrically is not WAMP compliant. Since the required framework is very simple we decided to define our own framework, inspired by WAMP, leaving out what we do not need and adding what we find missing. + +Basically what we need is very simple: we need to send a message (CALL) and receive a reply (CALLRESULT) or an explanation why the message could not be handled properly (CALLERROR). For possible future compatibility we will keep the numbering of these message in sync with WAMP. Our actual OCPP message will be put into a wrapper that at least contains the type of message, a unique message ID and the payload, the OCPP message itself. + +# 4.1.1. Synchronicity + +A Charge Point or Central System SHOULD NOT send a CALL message to the other party unless all the CALL messages it sent before have been responded to or have timed out. A CALL message has been responded to when a CALLERROR or CALLRESULT message has been received with the message ID of the CALL message. + +A CALL message has timed out when: + +- it has not been responded to, and +- an implementation-dependent timeout interval has elapsed since the message was sent. + +Implementations are free to choose this timeout interval. It is RECOMMENDED that they take into account the kind of network used to communicate with the other party. Mobile networks typically have much longer worst-case round-trip times than fixed lines. + +# NOTE + +The above requirements do not rule out that a Charge Point or Central System will receive a CALL message from the other party while it is waiting for a CALLERROR or CALLRESULT. Such a situation is difficult to prevent because CALL messages from both sides can always cross each other. + +# 4.1.2. Character encoding + +The whole message consisting of wrapper and payload MUST be valid JSON encoded with the UTF-8 (see [RFC3629]) character encoding. + +Note that all valid US-ASCII text is also valid UTF-8, so if a system sends only US-ASCII text, all messages it sends comply with the UTF-8 requirement. A Charge Point or Central System SHOULD only use characters not in US-ASCII for sending natural-language text. An example of such natural-language text is the text in the LocalizedText type in OCPP 2.0. + +# 4.1.3. The message type + +To identify the type of message one of the following Message Type Numbers MUST be used. + +Table 2: Message types + +
MessageTypeMessageTypeNumberDirection
CALL2Client-to-Server
CALLRESULT3Server-to-Client
CALLERROR4Server-to-Client
+ +When a server receives a message with a Message Type Number not in this list, it SHALL ignore the message payload. Each message type may have additional required fields. + +# 4.1.4. The message ID + +The message ID serves to identify a request. A message ID for a CALL message MUST be different from all message IDs previously used by the same sender for CALL messages on the same WebSocket connection. A message ID for a CALLRESULT or CALLERROR message MUST be equal to that of the CALL message that the CALLRESULT or CALLERROR message is a response to. + +Table 3: Unique Message ID + +
NameDatatypeRestrictions
messageIdstringMaximum of 36 characters, to allow for GUIs
+ +# 4.2. Message structures for different message types + +# NOTE + +You may find the charge point identity missing in the following paragraphs. The identity is exchanged during the WebSocket connection handshake and is a property of the connection. Every message is sent by or directed at this identity. There is therefore no need to repeat it in each message. + +# 4.2.1. Call + +A Call always consists of 4 elements: The standard elements MessageTypeDef and UniqueId, a specific Action that is required on the other side and a payload, the arguments to the Action. The syntax of a call looks like this: + +[ \langle MessageTypeError \rangle, \langle UniqueId \rangle, \langle Action \rangle, \{ \langle Payload \} \} ] + +Table 4: Call Fields + +
FieldMeaning
UniqueIdthis is a unique identifier that will be used to match request and result.
Actionthe name of the remote procedure or action. This will be a case-sensitive string containing the same value as the Action-field in SOAP-based messages, without the preceding slash.
PayloadPayload is a JSON object containing the arguments relevant to the Action. If there is no payload JSON allows for two different notations: null or and empty object {}. Although it seems trivial we consider it good practice to only use the empty object statement. Null usually represents something undefined, which is not the same as empty, and also {}. is shorter.
+ +For example, a BootNotification request could look like this: + +```json +[ + 2, + "19223201", + "BootNotification", + { "chargePointVendor": "VendorX", "chargePointModel": "SingleSocketCharger" } +] +``` + +# 4.2.2. CallResult + +If the call can be handled correctly the result will be a regular CallResult. Error situations that are covered by the definition of the OCPP response definition are not considered errors in this context. They are regular results and as such will be treated as a normal CallResult, even if the result is undesirable for the recipient. + +A CallResult always consists of 3 elements: The standard elements MessageTypeError and UniqueId and a payload, containing the response to the Action in the original Call. The syntax of a call looks like this: + +[ \left[ <\text{MessageTypeId}>, "<\text{UniqueId}>" \right], \left\{\langle\text{Payload}\rangle \right] ] + +Table 5: CallResult Fields + +
FieldMeaning
UniqueIdThis must be the exact same ID that is in the call request so that the recipient can match request and result.
PayloadPayload is a JSON object containing the results of the executed Action. If there is no payload JSON allows for two different notations: null or and empty object {}. Although it seems trivial we consider it good practice to only use the empty object statement. Null usually represents something undefined, which is not the same as empty, and also {}. is shorter.
+ +For example, a BootNotification response could look like this: + +```jsonl +[ + 3, + "19223201", + { + "status": "Accepted", + "currentTime": "2013-02-01T20:53:32.486Z", + "heartbeatInterval": 300 + } +] +``` + +# 4.2.3. CallError + +We only use CallError in two situations: + +1. An error occurred during the transport of the message. This can be a network issue, an availability of service issue, etc. +2. The call is received but the content of the call does not meet the requirements for a proper message. This could be missing mandatory fields, an existing call with the same unique identifier is being handled already, unique identifier too long, etc. + +A CallError always consists of 5 elements: The standard elements MessageTypeError and UniqueId, an errorCode string, an errorDescription string and an errorDetails object. The syntax of a call looks like this: + +[ \text{[}, \text{""} \text{""} \text{""} \text{, {}}\} ] + +Table 6: CallError Fields + +
FieldMeaning
UniqueIdThis must be the exact same id that is in the call request so that the recipient can match request and result.
ErrorCodeThis field must contain a string from theErrorCode table below.
DescriptionShould be filled in if possible, otherwise a clear empty string “”.
ErrorDetailsThis JSON object describes error details in an undefined way. If there are no error details you MUST fill in an empty object {}.

+ +# 5. Connection + +# 5.1. Compression + +Since JSON is very compact we recommend not to use compression in any other form than allowed as part of the WebSocket [RFC6455] specification. Otherwise it may compromise interoperability. + +# 5.2. Data integrity + +For data integrity we rely on the underlying TCP/IP transport layer mechanisms. + +# 5.3. WebSocket Ping in relation to OCPP Heartbeat + +The WebsSocket specification defines Ping and Pong frames that are used to check if the remote endpoint is still responsive. In practice this mechanism is also used to prevent the network operator from quietly closing the underlying network connection after a certain period of inactivity. This websocket feature can be used as a substitute for most of the OCPP Heartbeat messages, but cannot + +replace all of its functionality. + +An important aspect of the Heartbeat response is time synchronisation. The Ping and Pong frames cannot be used for this so at least one original Heartbeat message a day is recommended to ensure a correct clock setting on the Charge Point. + +# 5.4. Reconnecting + +When reconnecting a charge point should not send a BootNotification unless one or more of the elements in the BootNotification have changed since the last connection. For the previous SOAP based solutions this was considered good practice but when using WebsSocket the server can already make the match between the identity and a communication channel at the moment the connection is established. There is no need for an additional message. + +# 5.5. Network node hierarchy + +The physical network topology is not influenced by a choice for JSON or SOAP. In case of JSON however the issues with Network Address Translation (NAT) have been resolved by letting the Charge Point open a TCP connection to the Central System and keeping this connection open for communication initiated by the Central System. It is therefore no longer necessary to have a smart device capable of interpreting and redirecting SOAP calls in between the Central System and the Charge Point. + +# 6. Security + +Two approaches exist for security with OCPP-J. Either one can rely on network-level security, or one uses OCPP-J over TLS. Both approaches are described below. + +It is important that at all times, one of these approaches is used. Practically, this means that a Central System SHOULD NOT listen for incoming unencrypted OCPP-J connections from the internet. + +# 6.1. Network-level security + +For security one MAY rely on the security at a network level. This has historically been done with OCPP-S, and on networks that are set up appropriately one can also use OCPP-J without additional encryption or authentication measures. + +# 6.2. OCPP-J over TLS + +Sometimes however a secured network is not available between Charge Point and Central System. In that case one can use OCPP-J over TLS. This section explains how this is done. + +The security needed for OCPP communication actually consists of two separate features: encryption and charge point authentication. + +Encryption means that the OCPP messages are encrypted so no unauthorized third party can see the messages exchanged. + +Charge point authentication means that Central System can verify the identity of a charge point, so that no unauthorized third party can pretend to be a charge point and send malicious messages to a central system. + +# 6.2.1. Encryption + +The industry standard for encryption on the internet is Transport Layer Security (TLS) [RFC5246]. Therefore OCPP is also adopting protocol for encrypting the connection between Central System and Charge Point. TLS with WebSocket is widely supported by libraries and for clients should be hardly more difficult than using unencrypted WebSocket. + +When using TLS, the central system MAY also provide a signed certificate that a charge point can use to verify the central system's identity. + +As some Charge Point implementations are using embedded systems with limited computing resources, we impose an additional restriction on the TLS configuration on the server side: + +- The TLS certificate SHALL be an RSA certificate with a size no greater than 2048 bytes + +# 6.2.2. Charge point authentication + +For authentication, OCPP-J over TLS uses the HTTP Basic authentication scheme ([RFC2617]). The relatively simple HTTP Basic authentication can be used because the connection is already TLS-encrypted, so there is no need to encrypt the credentials a second time. + +When using HTTP Basic authentication, the client, i.e. the Charge Point, has to provide a username and password with its request. The username is equal to the charge point identity, which is the identifying string of the charge point as it uses it in the OCPP-J connection URL. The password is a 20-byte key that is stored on the charge point. + +# Example + +If we have a charge point with: + +- charge point identity "AL1000" +- authorization key 0001020304050607FFFFFFCCCCCCCCCCCC + +the HTTP authorization header should be: + +Authorization: Basic QUwxxMDAwOgABAgMEBQYH//// + +# A note on encryption + +The authentication mechanism via HTTP Basic Authentication is meant to be used on TLS-encrypted + +connections. Using this mechanism on an unencrypted connection means that anyone who can see the network traffic between Charge Point and Central System can see the charge point credentials, and can thus impersonate the Charge Point. + +# Setting the charge point's credentials + +For this charge point authentication scheme, the charge point needs to have an authentication key. This authentication key has to be transferred onto the charge point in some way. What is a good way depends on the business model of the charge point manufacturer and central system operator. + +# Setting during or before installation + +The desired, secure situation is that every charge point has its own, unique authorization key. If an authorization key is not unique, an attacker who discovers the authorization key of a single charge point can impersonate many or even all charge points in an operator's Central System. + +The simplest way to achieve this is to install the authorization key on the charge point during manufacture or installation. In these cases, the key will be securely communicated between the central system operator and installer or manufacturer by communication channels outside of OCPP. This scenario is secure because the key is not sent over the channel it is meant to secure, so an attacker eavesdropping the connection between Charge Point and Central System cannot impersonate the Charge Point. + +# Setting the key over OCPP + +If the processes of manufacturing, sale and installation of a charge point are not under the central system operator's control, there is no way to put a unique key on each individual charge point and also make sure the central system operator knows these keys and the charge points they belong to. For such scenarios, it is desirable for all charge points of a series to have the same "master" key when they leave the factory and are installed, or to have keys that are derived from the charge point identity by the same algorithm. Still the Central System operator will want to keep adversaries from impersonating all charge points of a series if the master key is leaked. For this use case, there is a possibility for the Central System to send a unique key to the charge point via OCPP after charge point installation. + +To set a charge point's authorization key via OCPP, the Central System SHALL send the Charge Point a ChangeConfiguration.req message with the key AuthorizationKey and as the value a 40-character hexadecimal representation of the 20-byte authorization key. If the Charge Point responds to this ChangeConfiguration.req with a ChangeConfiguration.conf with status Accepted, the Central System SHALL assume that the authorization key change was successful, and no longer accept the credentials previously used by the charge point. If the Charge Point responds to the ChangeConfiguration.req with a ChangeConfiguration.conf with status Rejected or NotSupported, the Central System SHALL keep accepting the old credentials. While the Central System SHALL still accept an OCPP-J connection from the Charge Point in this case, it MAY treat the Charge Point's OCPP messages differently, e.g. by not accepting the Charge Point's boot notifications. + +sd Onboarding a charge point, setting a new authorization key + +![](https://cdn-mineru.openxlab.org.cn/result/2025-11-07/418d8f77-cf55-42ff-ae2b-d120115d2ecc/450289d850293b35b88e5040ade4a3e90f1ffd71668f408d696decf06087d675.jpg) + +The charge point should not give back the authorization key in response to a GetConfiguration request. It can either not report the AuthorizationKey key at all or give back a value that is not related to the actual authorization key. + +Note that while sending a key over the channel to be secured is normally considered a bad practice, we believe it is appropriate here to at least offer the possibility to do so. Typically the authorization key will be set when a charge point is first 'on-boarded' in the central system. If the charge point then later produces the key that was set during on-boarding, it at least means this is the same system that connected during the on-boarding. While it may be possible to successfully on-board a spoofed new charge point to an adversary who knows the single "master" key for all new charge points, it is not + +possible to pretend to be an already-installed and operating charge point. This makes still makes a number of conceivable attacks impossible: + +- "reservation" of a charge point by spoofing messages marking it as occupied +- marking your just-started session on a public charge point as stopped so you won't have to pay as much +- sending many spoofed transactions and/or errors from already on-board charge points to confuse a central system operator's operations +- send spoofed transactions with another person's token ID to the central system to incur financial damage to the token ID's owner + +It is RECOMMENDED that the Central System operator makes setting the authorization key part of a charge point onboarding procedure, using the new OCPP 1.6 Pending value of the registration status in BootNotification.conf. A newly-connecting Charge Point will first get a Pending registration status on its first BootNotification.conf. The Central System will then set the Charge Point's unique authorization key with a ChangeConfiguration.req. Only when this ChangeConfiguration.req has been responded to with a ChangeConfiguration.conf with a status of Accepted, will the Central System respond to a boot notification with an Accepted registration status. + +It is RECOMMENDED that the Central System operator checks for anomalies in the newly-connecting charge points. Thus he can try to detect if an attacker has managed to steal the master key or key derivation algorithm, and a list of registered charge point identities. For example, if the rate at which new charge points connect suddenly increases, this may indicate an attack. + +# Storing the credentials + +It is important that the credentials are stored on the Charge Point in such a way that they are not easily lost or reset. If the credentials are lost, erased or changed unilaterally, the Charge Point can no longer connect to the Central System and requires on-site servicing to install new credentials. + +On the Central System side, it is RECOMMENDED to store the authorization key hashed, with a unique salt, using a cryptographic hash algorithm designed for secure storage of passwords. This makes sure that if the database containing the charge points' authorization keys is leaked, the attackers still cannot authenticate as the charge points to the Central System. + +# 6.2.3. What it does and does not secure + +The scope of these security measures is limited to authentication and encryption of the connection between Charge Point and Central System. It does not address every current security issue in the EV Charging IT landscape. + +It does provide the following things: + +- authentication of the Charge Point to the Central System (using HTTP Basic Authentication) +- encryption of the connection between Charge Point and Central System + +- authentication of the Central System to the Charge Point (with a TLS certificate) + +It does not provide: + +- A guarantee that the meter values are not tampered with between the meter and the Central System + Authentication of the driver +- Protection against people physically tampering with a charge point + +# 6.2.4. Applicability to OCPP-S + +The approach of OCPP-J over TLS cannot be applied to OCPP-S. There are two reasons. + +Firstly, in OCPP-S a new TCP connection is created for every request-response exchange. One would thus have to do a new TLS handshake for each such request-response exchange, incurring a great bandwidth overhead. + +Secondly, in OCPP-S the Charge Point also acts as a server, and would thus need a server certificate. It would be a great administrative burden to keep track of so many server certificates and the charge points they belong to. + +# 7. Configuration + +The following items in OCPP Get/ChangeConfiguration messages are added to control JSON/WebSockets behaviour: + +Table 8: Additional OCPP Keys + +
KeyValue
WebSocketPingIntervalinteger A value of 0 disables client side websocket Ping / Pong. In this case there is either no ping / pong or the server initiates the ping and client responds with Pong. Positive values are interpreted as number of seconds between pings. Negative values are not allowed. ChangeConfiguration is expected to return a REJECTED result.

+ +# Contents + +# 1. Introduction + +# 1.1. Purpose of this document + +The purpose of this document is to give the reader the information required to create a correct interoperable OCPP SOAP implementation (OCPP-S). We will try to explain what is mandatory, what's considered good practice and what you should not do, based on our own experience. Undoubtedly there will remain misunderstandings or ambiguities but by means of this document we aim to prevent them as much as possible. + +# 1.2. Intended audience + +This document is intended for developers looking to understand and/or implement OCPP SOAP in a correct and interoperable way. Rudimentary knowledge of implementing web services on a server or embedded device is assumed. + +# 1.3.OCPP-S and OCPP-J + +With the introduction of OCPP 1.6, there are two different flavours of OCPP; next to the SOAP based implementations, there is the possibility to use the much more compact JSON alternative. To avoid confusion in communication on the type of implementation we recommend using the distinct extensions J and S to indicate JSON or SOAP. In generic terms this would be OCPP-J for JSON and OCPP-S for SOAP. Version specific terminology would be OCPP1.6J or OCPP1.2S. If no extension is specified for OCPP 1.2 or 1.5 then a SOAP implementation must be assumed. As of release 1.6 this can no longer be implicit and should always be made clear. If a system supports both the JSON and SOAP variant it is considered good practice to label this OCPP1.6JS i.s.o. just OCPP1.6. + +This document describes OCPP-S, for OCPP-J see: [OCPP_IMP_J] + +# 1.4. Conventions + +The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. + +# 1.5.

+ +# 2. Binding to Transport Protocol + +This section describes how the OCPP PDUs can be conveyed over SOAP. + +The rationale behind using SOAP as a transport is that SOAP already provides the infrastructure of sending messages. SOAP has a good support in the industry, which results in tools that improve the ease of implementing the protocol. + +The used version of SOAP MUST be 1.2. See [SOAP]. Please note that this has no relationship with the 1.2 version number of the OCPP specification. + +# 3. SOAP Header + +Although we refer to the officially released version of the WS-Addressing specification we see a lot of confusion on the meaning and necessity of fields in the SOAP header. To avoid confusion we will explicitly state what should be in a SOAP header. Anything that we do not specify in this chapter is + +optional or not necessary, in compliance with the WS-A specification. + +# 3.1. XML Declaration + +An XML declaration is not part of the soap message but is necessary for some systems to correctly interpret the message. It specifies the XML version and encoding of what is to come. Therefore each OCPP-S message SHOULD be preceded by the following: + +```txt + + + +CP1234 +``` + +When a Central System needs to send requests to a Charge Point, the Central System MUST specify in each request the "chargeBoxIdentity" of the Charge Point for which the request is intended. If the receiving Charge Point is not the intended one, and it cannot relay the message to a node that knows this Charge Point, then the Charge Point MUST send a SOAP Fault Response message, indicating that the identity is wrong (e.g. sub-code is "IdentityMismatch"). + +The mustUnderstand attribute indicates enforces that the receiver MUST send an error of it cannot handle the specified field, in this case chargeBoxIdentity. If mustUnderstand is not specified or false, the receiver could choose to ignore messages for unknown identities. + +# 3.4. Action + +# Required: Yes + +The action field contains the type of OCPP message for which the parameters are included in the body. The content of this field should always start with a “/”, followed by the name of the message, starting with a capital letter. For response messages the action keyword must be extended with “Response”. + +Example: + +```asp + +``` + +or + +```txt + HeartbeatResponse +``` + +Note that here we also use the mustUnderstand to enforce that messages containing an unknown action are not discarded but trigger an error response. + +# 3.5. MessageID + +# Required: Yes + +Each message can be given a unique message ID before sending. The purpose of this field is enable matching of an incoming response to a previously sent request. + +At first glance the official 1.0 Web Service Addressing Core specification ([WSA]) marks this field as “/OPTIONAL”. However, in paragraph 3.4 of this spec (Formulating a Reply Message), section 1 (Select the appropriate EPR), third bullet it casually states: + +"In either of the above cases, if the related message lacks a [message id] property, the processor MUST fault." + +The mentioned "related message" refers to the request. So, even though it is optional this line makes not having it in the request a reason to reject the message and thus implicitly makes it mandatory in a request-response context. + +# NOTE + +Because of this mandatory/optional discussion for this particular field we discovered that in most pre-releases of the official 1.0 WSA Core spec the MessageID is mandatory. We also discovered that some frameworks are actually based on those pre-releases and may contain other errors as well. Please verify that (if you use a framework) your framework is based on the final specification. + +# 3.6. RelatesTo + +# Required: Yes, for responses only + +RelatesTo should not be filled in for request messages. It only has meaning, and must be present, in response messages. When used it should contain the value of the MessageID field of the related request message. + +# 3.7. From + +# Required: Yes + +According to the WS-A 1.0 Core specification the from-field is marked as optional. However, for OCPP the field MUST be filled in. It is the only way for a Central System to know how to address server-initiated messages to a Charge Point. The address specified must be the address where the sender listens for incoming SOAP requests. + +# Example: + +```xml + http://62.133.94.210:12345 +``` + +# 3.8. ReplyTo + +# Required: Yes + +According to the WS-A 1.0 Core specification this field is marked as optional. If omitted, the default value is "http://www.w3.org/2005/08/addressing/anonymous". In accordance with section 5.1.2 of the WS-A 1.0 SOAP Binding specification the use of such anonymous response endpoints forces the response to be in the same instance of the SOAP request-response MEP. In other words, omitting or explicitly specifying the anonymous url makes the soap communication synchronous. + +Strictly speaking for OCPP this means that any other explicit value than the anonymous url would be an incorrect value. + +# Example: + +```rdf + http://www.w3.org/2005/08/addressing/anonymous +``` + +# 3.9. To + +# Required: Yes + +According to the WS-A 1.0 Core specification this field is marked as optional. However, if this field is omitted because it is optional the implicit value is "http://www.w3.org/2005/08/addressing/anonymous". What this means of how it should affect SOAP behavior is unspecified. For OCPP we require the To field to be filled in with the correct web service address of the recipient. + +# Example: + +```txt + +http://some.backoffice.com/ocpp/v1/5 + +``` + +# 4. Fault Response + +In cases where the receiving party (e.g. Charge Point or Central System) cannot process the request and the corresponding confirmation PDU does not have to ability to report the error, then the SOAP Fault Response Message SHOULD be used. This can be used, for instance, when the operation is not implemented or when an internal error has occurred. + +If a sender receives a SOAP Fault Response from the receiver, the sender SHOULD NOT resend the same message. + +The following fault codes can be used by the service: + +Code, Reason and Value belong to the namespace "http://www.w3.org/2003/05/soap-envelope". + +This example SubCode belongs to the namespace "urn://Ocpp/Cs/2015/10" + +Table 1: Fault Response SubCodes + +

+ +# 5. Mobile Networks + +In cases where Charge Points use an IP based mobile data network (GPRS, UMTS, HSPDA, etc.) to communicate with the Central System, it's possible that the Central System cannot initiate a network connection to a Charge Point directly. For example, a Network Operator may use dynamic IP addresses. + +To overcome this problem, a Central System SHOULD send a SMS to a Charge Point. The SMS SHOULD contain the Charge Point identifier, but the SMS MAY also be empty. How an SMS is sent to an SMSC and delivered to the Charge Point is outside the scope of this specification. Upon receipt of a SMS, the Charge Point MUST send a Heartbeat.req PDU to the Central System with WS-Addressing header "From", with the URL of the Charge Point. See [WS-ADDR] for a description of the Web Service Addressing standard. The Central System SHOULD use this URL for sending a pending command to. + +When Charge Points are deployed in a mobile network, the Charge Point SHOULD set its URL in the WS-Addressing "From" field when sending a request. This way a Central System can first try sending commands to the supplied URL, before waking up the Charge Point via SMS. + +![](https://cdn-mineru.openxlab.org.cn/result/2025-11-07/d4536a2c-9dc4-406c-be76-d4e5e3c061b0/1e19b4d1a1c0e5f10be290fb0037005ca8a986a1c49d6ea4cf84d9d0163acd56.jpg) +sd Wake-up of a charge point by SMS + +# 6. Connection + +# 6.1. Compression + +In cases where bandwidth needs to be reduced, a communicating party can use of the HTTP capability of compressing data. HTTP defines a 'Content-Encoding' header, which contains the compression method. + +The Charge Point and Central System MAY use HTTP compression. Compression can be performed on a HTTP request and/or response. + +The Charge Point and Central System MUST support the 'gzip' and 'deflate' compression methods. These are the most common compression methods. + +When using compression, one should take great care if indeed the message size decreases. If the message is small, then it's possible that the compression will increase the size. + +# 6.2. Security + +To avoid exposure of private sensitive data, the transport of SOAP messages SHOULD be secured with SSL/TLS (e.g. HTTPS). + +For a receiving party to trust a received message, the sending party SHOULD use a client certificate. + +# 7. SOAP specific OCPP requirements + +# 7.1. BootNotification + +If the SOAP connection to the Central System is lost, the Charge Point SHALL re-establish it. If the Charge Point is not sure that its IP Address has not changed, it SHOULD send a new BootNotification to the Central Server. In other words: If the IP Address of the Charge Point can have changed, the Charge Point SHOULD send a new BootNotification. The Central System needs the new IP Address, to be able to send Central System initiated messages to the Charge Point. + +# 8.

+ +# Scope + +This document contains errata on the OCPP 2.0.1 documentation. These errata have to be read as an addition to the release of OCPP 2.0.1 Edition 3. + +The errata do not affect any schemas of OCPP messages. Certain errata do contain changes to requirements or even new requirements, but only in cases where a requirement contains an obvious error and would not or could not be implemented literally. New requirements are only added when they were already implicitly there. These changes have been discussed in or were proposed by the Technology Working Group of the Open Charge Alliance. + +The appendices of the OCPP specification can be updated without requiring a new OCPP release. This mainly concerns the components and variables of the OCPP device model, which can be extended with new components or variables, as long as they are optional. + +# Terminology and Conventions + +Bold: when needed to clarify differences, bold text might be used. + +The errata entries are sorted by page number of the affected section of the specification document. When an errata entry affects multiple parts of the specification, then the various changes are grouped together with subsections referring to the pages affected by those changes. + +This is version 2025-09 of the errata. The errata of this version are marked with "(2025-09)" in the section title. + +In some cases the issue number by which it was reported, is added in square brackets at the end of the section title, e.g. "[349]". For retrieval of the issue in the issue tracking system prefix the number with "OCPP20M", like "[OCPP20M-349]". + +# 0. Part 0 + +Currently no new errata for OCPP 2.0.1 Edition 3 part 0. + +# 1.

No.TypeDescription
1NameUpgrade Charging Station Security Profile
2IDA05
Functional blockA. Security
3Objective(s)The CSO wants to increase change the security of the OCPP connection between CSMS and a Charging Station.
4DescriptionUse case when migrating from OCPP 1.6 without security profiles to OCPP 2.0.1. Before migrating to a security profile, the prerequisites, like installed certificates or password, need to be configured.
ActorsCSMS, Charging Station
Scenario description1. The CSMS sets a new value for the NetworkConfigurationPriority Configuration Variable via SetVariablesRequest, such that the NetworkConnectionProfile for the new (higher) security profile becomes first in the list and the existing connection profile becomes second in the list. +2. The Charging Station responds with a SetVariablesResponse with status Accepted +3. The CSMS sends a ResetRequest(OnIdle) +4. The Charging Station reboots and connects via the new primary NetworkConnectionProfile
5Prerequisite(s)The CSO ensures that a NetworkConnectionProfile has been set using (higher) an allowed security profile AND that the prerequisite(s) for going to a higher the new security profile are met before sending the command to change to a higher the new security profile.
6Postcondition(s)The Charging Station was successfully upgraded to a higher new security profile.
7Error handlingn/a
8Remark(s)For security reasons it is by default not allowed to revert to a lower Security Profile using OCPP. +Only when the variable AllowSecurityProfileDowngrade is implemented and is set to true, it is allowed to downgrade from profile 3 to profile 2. Even in that case, it is not allowed to revert from profile 2 or profile 3 to security profile 1 using OCPP.
+ +Changed A00 requirement: + +
IDPreconditionRequirement definition
Old textA00.FR.005Lowering the security profile that is used, to a less secure profile, is for security reasons, not part of the OCPP specification, and MUST be done through another method, not via OCPP. OCPP messages SHALL NOT be used for this (e.g. SetVariablesRequest or DataTransferRequest).
New textA00.FR.005Lowering the security profile that is used, to a less secure profile, is for security reasons, not recommended.The Charging Station SHALL only allow to lower the security profile if the variable AllowSecurityProfileDowngrade is implemented and set to true . In that case, the Charging Station SHALL only allow to downgrade from profile 3 to profile 2.

IDPreconditionRequirement definition
A00.FR.430If the Charging Station certificate has expiredThe Charging Station SHOULD still attempt to establish a connection with the CSMS and leave the decision to accept the connection up to the CSMS.
+ +# 2.7. Page 28 - (2025-01) - Certificate Hierarchy + +A note has been added to the specification to warn OCPP implementers about the potential risks involved with the installation of CA bundles. + +# 2.8. Page 31 - (2025-01) - A02/A03 - Updated error handling + +NOT RECOMMENDED in the error handling is confusing as there is already a requirement that explicitly states that the Charging Station SHALL retry after "CertSigningWaitMinimum". + +
7Error handlingThe CSMS accepts the CSR request from the Charging Station, before forwarding it to the CA. But when the CA cannot be reached, or rejects the CSR, the Charging Station will never be known. The CSMS may do some checks on the CSR, but cannot do all the checks that a CA does, and it does not prevent connection timeout to the CA. When something like this goes wrong, either the CA is offline or the CSR send by the Charging Station is not correct, according to the CA. In both cases this is something an operator at the CSO needs to be notified of. The operator then needs to investigate the issue. When resolved, the operator can re-run A02. It is NOT RECOMMENDED to let the Charging Station retry when the certificate is not send within X minutes or hours. When the CSR is incorrect, that will not be resolved automatically. It is possible that only a new firmware will fix this.
+ +# 2.9. Page 34 - (2025-01) - Disallow client certificates future validity date + +Currently the specification is unclear on whether accepting client certificates with a future validity date is intended behavior. If it would be allowed behavior, several problems were identified. For example, there would be no way for the CSMS to manage these (ghost) client certificates using OCPP. ENCS was consulted if there would be any security risks when not allowing accepting client certificates with a future validity date. ENCS identified no security risks, therefore it was decided to not allow accepting client certificates with a future validity date. In addition clarifications have been made to describe how to handle non-happy flow scenarios in which the Charging Station is unable to successfully connect using the new client certificate in combination with the NetworkConnectionProfile mechanism described at use case B10. + +Changed/added A02 requirements: + +
IDPreconditionRequirement definitionNote
Old textA02.FR.06The Charging Station SHALL verify the validity of the signed certificate in the CertificateSignedRequest message, checking at least the period when the certificate is valid, the properties in Certificate Properties, and that it is part of the Charging Station Operator certificate hierarchy as described in Certificate Hierarchy.
New textA02.FR.06The Charging Station SHALL verify the validity of the signed certificate in the CertificateSignedRequest message, checking that the current date (at the time of the update) is within the certificate's validity period, the properties in Certificate Properties, and that it is part of the Charging Station Operator certificate hierarchy as described in Certificate Hierarchy.When providing a newly signed client certificate with a start period that equals the current time, the CSMS should take into account that there might be a slight discrepancy in the time between the Charging Station and CSMS. This could cause the Charging Station to reject the new certificate, because in case a small time difference exists, the validity period might (just) be in the future for the device.
Old textA02.FR.08The Charging Station SHALL switch to the new certificate as soon as the current date and time is after the 'Not valid before' field in the certificate (e.g. by closing the websocket and TLS connection and reconnecting with the new certificate).
+ +Changed/added A03 requirements: + +
IDPreconditionRequirement definitionNote
New textA02.FR.08If the certificate is valid.The Charging Station SHALL respond to the CertificateSignedRequest with status Accepted AND the Charging Station SHALL switch to the new certificate by reconnecting the websocket and TLS connection.
Old textA02.FR.09If the Charging Station contains more than one valid certificate of the ChargingStationCertificat e type.The Charging Station SHALL use the newest certificate, as measured by the start of the validity period.

+ +# 2.17. Page 77 - (2025-01) - 1.6 Relationship between authorization and transaction + +A new section has been added after 1.5 Unknown Offline Authorization + +This section is informative. + +The purpose of authorization is twofold. It ensures in the first place, that energy is only offered to a known user (represented by the idToken), which is essential for billing. In the second place, it ensures that only the user who was authorized in the first place (or a member of the same group of users) is allowed to unplug the cable. This is an important safeguard against cable theft in situations where the charging station does not have a fixed cable and the user brings its own charging cable. + +Authorization and the duration of the authorization period are not strictly tied to a transaction: it is possible to have transactions without explicit authorization, e.g. in the case of a charging station that can be started with a push button. In that case one could say that there is a permanent authorization for anyone to charge. + +The start of the authorization period: + +- can take place before a transaction is started (e.g. when a cable is not yet connected), or +- can cause a transaction to be started (e.g. when authorization is defined as the start of a transaction by setting TxStartPoint = Authorized), or +- can happen after a transaction has already started (e.g. when connection of the cable is defined as the start of a transaction by setting TxStartPoint = EVConnected). + +(See chapter E.1.1 "Flexible transaction start/stop" for a description of transaction start and stop points.) + +In any case, authorization (or authorization period) ends when the same idToken is presented again for authorization, or when the transaction ends.

Charging Station notifies CSMS about this, as follows: + +- If authorization occurs before start of the transaction, Charging Station tells CSMS that authorization has taken place, by including the idToken in the first TransactionEventRequest of the transaction. +- If authorization occurs within a transaction or at the start of a transaction, Charging Station reports this by including the idToken in TransactionEventRequest together with a triggerReason = Authorized. + +# 2.18.

Old textThis Functional Block describes the reservation functionality of OCPP. The reservation functionality enables an EV Driver to make a reservation of a Charging Station/EVSE, ensuring an available Connector at a Charging Station when he arrives. +With Charging Stations not being abundantly available, and EVs having limited range, EV Drivers plan their trips from Charging Station to Charging Station. They need to know for sure they can use a Charging Station they plan to go to. They don't like it when another EV Driver has started using the Charging Station in the time they were traveling to the Charging Station. +For the EV Driver it is useful to be able to reserve a specific Type of Connector, or, when the EV Driver has no preference, an unspecified EVSE at a Charging Station. So he knows for sure he can charge at the Charging Station when he arrives.
New textThis Functional Block describes the reservation functionality of OCPP. The reservation functionality enables an EV Driver to reserve an EVSE at a Charging Station until a certain time in order to ensure that this EVSE cannot be occupied by another user. +OCPP allows to reserve a specific EVSE at a Charging Station or a specific connector type. The EV Driver can also reserve an unspecified EVSE, in which case the Charging Station will make sure that at least one EVSE remains available for the EV Driver. +Only available EVSEs can be reserved, since a Charging Station cannot know in advance when an occupied EVSE will become available again. This makes it impossible to guarantee a reservation for an EVSE that is currently occupied. +NOTE: A CSMS would still be able to support the reservation functionality for occupied EVSEs by delaying the sending of the reservation message to the Charging Station until the EVSE becomes available, but there is no guarantee that it is available in time.

As described in the above, this means that a Charging Station Operator (CSO) CSMS controls a Charging Station and, based on the charging limits of both the EV and the Charging Station, the CSO determines how fast the EV is charged. However, in some situations / applications of OCPP enabled Charging Stations, these are not the only 2 factors that determine the charging speed. Other inputs that determine charging speed could be DSO signals (e.g. via IEC 61850 [IEC61850-7-420], IEC 60870 [IEC60870-5-104], DNP3 [DNP3] or OpenADR [OPENADR]) or signals from a Building / Home Energy Management System. Although these signals are out of scope for OCPP, it seems clear from an OCPP perspective that the CSMS is to be informed of changes in charging by external signals. However, this also leads to a number of questions, such as how to deal with conflicting signals.

3Objective(s)To illustrate the process of local load-balancing by a Local Cluster.
4DescriptionThis use case is an example of how local load-balancing can be performed. It does not imply that other approaches would not be correct. The process has been simplified for clarity and should not be regarded as prescriptive.A Local Controller is configured with a value for maximum current for the total cluster by CSMS via a charging profile of type ChargingStationMaxProfile to the Local Controller, or an EMS may have set a ChargingStationExternalConstraints charging profile.The Local Controller divides the maximum current among the active transactions. Whenever a transaction starts or finishes, the Local Controller will update the charging profiles of the remaining transactions to divide the maximum current equally.For simplicity's sake, this use case does not differentiate on departure time or state of charge of vehicles, nor does it take the actual energy consumption of vehicles into account.
ActorsCharging Station (CS01, CS02), Local Controller (LC), CSMS
Scenario descriptionAssume no transactions are active in the local cluster and the maximum current for the local cluster has been configured to be 100 A. The charging stations all have a TxDefaultProfile that allows a current of only 6 A, so that vehicles cannot immediately start charging at full power before the LC had the chance to set a charging profile.1. A transaction starts on charging station CS01. It sends a TransactionEventRequest(Started) to LC.2. LC is configured to do local load-balancing (i.e. its SmartChargingCtrl.Enabled = true), so it registers the transaction id TX1 of the transaction that has been started on CS01, before forwarding the message on the websocket for CS01 towards CSMS.3. LC sends a SetChargingProfileRequest to CS01 with chargingProfilePurpose = TxProfile, chargingProfileKind = Relative, transactionId = TX1 and a chargingSchedule with a chargingRateUnit = A that contains one chargingSchedulePeriod with a limit of 94 A, so that the entire quota is available to this transaction minus the TxDefaultProfile amount for new transactions.4. Another transaction starts on charging station CS02. It sends a TransactionEventRequest(Started) to LC.5. LC registers the new transaction id TX2 and forwards the message on the websocket for CS02 to CSMS.6. LC divides the available quota by allowing each transaction a maximum of 47 A.7. LC sends a SetChargingProfile message to CS01 that updates the existing TxProfile and sets the limit to 47 A.8. LC sends new SetChargingProfile to CS02 with chargingProfilePurpose = TxProfile, chargingProfileKind = Relative, transactionId = TX2 and a chargingSchedule with a chargingRateUnit = A that contains one chargingSchedulePeriod with a limit of 47 A.9. The transaction of CS01 finishes. It sends a TransactionEventRequest(Ended) to LC.10. LC registers that transaction TX1 on CS01 has finished and forwards the message on the websocket for CS01 to CSMS.11. LC now allows the maximum to TX2. It sends a SetChargingProfile message to CS02 that updates the existing TxProfile and sets the limit to 94 A. (Note, that the TxProfile for TX1 on CS01 has automatically ceased to exist upon termination of the transaction.)
5PrerequisitesThe LC has been configured with a fixed maximum current level.The SmartChargingCtrl component of Local Controller has been Enabled, which will trigger the Local Controller to read and interpret TransactionEventRequest messages from connected Charging Stations.
6Post conditions
7Error Handling
8RemarksAs described in Part 1, a Local Controller replicates all web sockets from Charging Stations in the cluster towards CSMS, and forwards messages from Charging Station to CSMS on the appropriate web socket (and vice versa). This allows the Local Controller to read messages, such as a TransactionEventRequest message, from the Charging Station.The Local Controller for local smart charging can be implemented in different ways, for example: as a separate physical component or as part of a "master" Charging Station controlling a number of other Charging Stations. The Local Controller MAY or MAY NOT have any EVSEs of its own.The limits on Charging Stations in a Local Smart Charging group can either be pre-configured in the Local Controller in one way or another, or they can be set by the CSMS. The Local Controller contains the logic to distribute this capacity among the connected EVSEs by adjusting their limits as needed.

EnergyTransferEnergy is being transferred between EV and EVSE.
Note: Since energy needs to start flowing first to cause the transaction to be started, there is a small time gap (order of milliseconds) between the start of energy transfer and start of transaction.

DescriptionThe CSMS uses a server-side certificate to identify itself to the Charging Station, when using security profile 2 or 3.
PurposeTo verify whether the Charging Station is able to terminate the connection when the received server certificate is invalid.

Main(Test scenario)Charging StationCSMS
1. The OCTT aborts the connection with the Charging Station.
2. The Charging Station initiates a TLS handshake and sends a Client Hello to the OCTT.3. The OCTT responds with a Server HelloWith a <Configured valid server certificate>Note(s):- The OCTT will use this as an indication of the time it takes the Charging Station to reconnect.
4. The OCTT aborts the connection with the Charging Station.
5. The Charging Station initiates a TLS handshake and sends a Client Hello to the OCTT.6. The OCTT responds with a Server HelloWith a <Configured invalid server certificate>
7. The Charging Station deems the server certificate invalid and terminates the connection.
Note: The OCTT will wait two times the measured reconnection time from step 3, before switching the server certificate back to the valid server certificate. The reason for this is that the OCTT is not always able to detect a failed connection attempt.
8. The Charging Station initiates a TLS handshake and sends a Client Hello to the OCTT.9. The OCTT responds with a Server HelloWith a <Configured valid server certificate>Note(s):- The OCTT will accept the connection to prevent doubling of the RetryBackOffWaitMinimum.
10 The Charging Station sends aSecurityEventNotificationRequest11 The OCTT responds with aSecurityEventNotificationResponse
Note(s):- Steps 4 to 11 are repeated per configured invalid server certificate.- In case default certificates are being used, the OCTT will use three different invalid server certificates; "Not signed by installed Root certificate", "Expired", "CommonName that does not equal the FQDN of the server".- In case custom certificates are being used, the OCTT will loop through all certificates configured at the 'CSMS Keystore Invalid'.
