9 [![Javascript Standard Style Guide](<https://badgen.net/static/code style/standard/green>)](https://standardjs.com)
13 Simple [node.js](https://nodejs.org/) software to simulate and scale a set of charging stations based on the OCPP-J protocol as part of [SAP e-Mobility](https://www.sap.com/products/scm/e-mobility.html) solution.
17 Install the [node.js](https://nodejs.org/) current LTS or superior version runtime environment:
21 - [Chocolatey](https://chocolatey.org/):
24 choco install -y nodejs
29 - [Homebrew](https://brew.sh/):
37 - [NodeSource](https://github.com/nodesource/distributions) Node.js Binary Distributions for all supported versions.
41 Enable corepack if not already done and install latest pnpm version:
45 corepack prepare pnpm@latest --activate
48 In the repository root, run the following command:
54 ## Initial configuration
56 Copy the configuration template file [src/assets/config-template.json](src/assets/config-template.json) to [src/assets/config.json](src/assets/config.json).
57 Copy the RFID tags template file [src/assets/idtags-template.json](src/assets/idtags-template.json) to [src/assets/idtags.json](src/assets/idtags.json).
59 Tweak them to your needs by following the section [configuration files syntax](README.md#configuration-files-syntax): OCPP server supervision URL(s), charging station templates, etc.
63 To start the program, run: `pnpm start`.
67 See Web UI [README.md](ui/web/README.md) for more information.
69 ## Configuration files syntax
71 All configuration files are in the JSON standard format.
73 **Configuration files locations**:
75 - charging stations simulator configuration: [src/assets/config.json](src/assets/config.json);
76 - charging station configuration templates: [src/assets/station-templates](src/assets/station-templates);
77 - charging station configurations: [dist/assets/configurations](dist/assets/configurations);
78 - charging station RFID tags lists: [src/assets](src/assets).
80 The charging stations simulator's configuration parameters must be within the `src/assets/config.json` file. A charging station simulator configuration template file is available at [src/assets/config-template.json](src/assets/config-template.json).
82 All charging station configuration templates are in the directory [src/assets/station-templates](src/assets/station-templates).
84 A list of RFID tags must be defined for the automatic transaction generator in a file with the default location and name: `src/assets/idtags.json`. A template file is available at [src/assets/idtags-template.json](src/assets/idtags-template.json).
86 **Configuration files hierarchy and priority**:
88 1. charging station configuration: [dist/assets/configurations](dist/assets/configurations);
89 2. charging station configuration template: [src/assets/station-templates](src/assets/station-templates);
90 3. charging stations simulator configuration: [src/assets/config.json](src/assets/config.json).
92 The charging stations simulator has an automatic configuration files reload feature at change for:
94 - charging stations simulator configuration;
95 - charging station configuration templates;
96 - charging station authorization RFID tags lists.
98 But the modifications to test have to be done to the files in the build target directory [dist/assets](dist/assets). Once the modifications are done, they have to be reported to the matching files in the build source directory [src/assets](src/assets) to ensure they will be taken into account at next build.

320 ### Charging station configuration
322 **dist/assets/configurations/\<hashId\>.json**:
324 The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent.
326 The charging station configuration file content can be regenerated partially on matching charging station configuration template file changes. The charging station serial number is kept unchanged.
328 #### stationInfo section
330 The syntax is similar to charging station configuration template with some added fields like the charging station id (name) and the 'Configuration' section removed.
332 That section is overwritten on matching charging station configuration template file changes.
334 #### connectorsStatus section
336 The syntax is similar to charging station configuration template 'Connectors' section with some added fields.
338 That section is overwritten on matching charging station configuration template file changes.
340 #### evsesStatus section
342 The syntax is similar to charging station configuration template 'Evses' section with some added fields.
344 That section is overwritten on matching charging station configuration template file changes.
346 #### automaticTransactionGenerator section
348 The syntax is similar to the charging station configuration template 'AutomaticTransactionGenerator' section.
350 That section is overwritten on matching charging station configuration template file changes.
352 #### automaticTransactionGeneratorStatuses section
354 That section is not overwritten on matching charging station configuration template file changes.
356 #### configurationKey section
358 The syntax is similar to the charging station configuration template 'Configuration' section.
360 That section is not overwritten on matching charging station configuration template file changes.

501 Protocol to control the simulator via a Websocket or HTTP server.
505 To learn how to use the HTTP protocol to pilot the simulator, an [Insomnia](https://insomnia.rest/) HTTP requests collection is available in [src/assets/ui-protocol](./src/assets/ui-protocol) directory.
507 ### Websocket Protocol
509 SRPC protocol over Websocket. PDU stands for 'Protocol Data Unit'.
