11 ## Summary
12
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.
14
15 ## Prerequisites
16
17 Install the [node.js](https://nodejs.org/) current LTS or superior version runtime environment:
18
19 ### Windows
20
21 - [Chocolatey](https://chocolatey.org/):
22
23 ```powershell
24 choco install -y nodejs
25 ```
26
27 ### MacOSX
28
29 - [Homebrew](https://brew.sh/):
30
31 ```shell
32 brew install node
33 ```
34
35 ### GNU/Linux
36
37 - [NodeSource](https://github.com/nodesource/distributions) Node.js Binary Distributions for all supported versions.
38
39 ## Installation
40
41 Enable corepack if not already done and install latest pnpm version:
42
43 ```shell
44 corepack enable
45 corepack prepare pnpm@latest --activate
46 ```
47
48 In the repository root, run the following command:
49
50 ```shell
51 pnpm install
52 ```
53
54 ## Initial configuration
55
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).
58
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.
60
61 ## Start
62
63 To start the program, run: `pnpm start`.
64
65 ## Start Web UI
66
67 See Web UI [README.md](ui/web/README.md) for more information.
68
69 ## Configuration files syntax
70
71 All configuration files are in the JSON standard format.
72
73 **Configuration files locations**:
74
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).
79
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).
81
82 All charging station configuration templates are in the directory [src/assets/station-templates](src/assets/station-templates).
83
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).
85
86 **Configuration files hierarchy and priority**:
87
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).
91
92 The charging stations simulator has an automatic configuration files reload feature at change for:
93
94 - charging stations simulator configuration;
95 - charging station configuration templates;
96 - charging station authorization RFID tags lists.
97
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.

322 ### Charging station configuration
323
324 **dist/assets/configurations/\<hashId\>.json**:
325
326 The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent.
327
328 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.
329
330 #### stationInfo section
331
332 The syntax is similar to charging station configuration template with some added fields like the charging station id (name) and the 'Configuration' section removed.
333
334 #### configurationKey section
335
336 The syntax is similar to the charging station configuration template 'Configuration' section.
337
338 #### automaticTransactionGenerator section
339
340 The syntax is similar to the charging station configuration template 'AutomaticTransactionGenerator' section.
341
