| 2 | |
| 3 | ## Summary |
| 4 | |
| 5 | Simple [node.js](https://nodejs.org/) software to simulate a set of charging stations based on the OCPP-J 1.6 protocol as part of SAP e-Mobility solution. |
| 6 | |
| 7 | ## Prerequisites |
| 8 | |
| 9 | ### Windows |
| 10 | |
| 11 | - [Chocolatey](https://chocolatey.org/): |
| 12 | |
| 13 | ```powershell |
| 14 | choco install -y nodejs-lts |
| 15 | ``` |
| 16 | |
| 17 | ### MacOSX |
| 18 | |
| 19 | - [Homebrew](https://brew.sh/): |
| 20 | |
| 21 | ```shell |
| 22 | brew install node@16 |
| 23 | ``` |
| 24 | |
| 25 | ### GNU/Linux: |
| 26 | |
| 27 | - [NodeSource](https://github.com/nodesource/distributions) Node.js Binary Distributions for version 16.X |
| 28 | |
| 29 | ## Configuration files syntax |
| 30 | |
| 31 | All configuration files are in the JSON standard format. |
| 32 | |
| 33 | **Configuration files list**: |
| 34 | |
| 35 | - charging stations simulator configuration: [src/assets/config.json](src/assets/config.json); |
| 36 | - charging station configuration templates: [src/assets/station-templates](src/assets/station-templates); |
| 37 | - charging station configurations: [dist/assets/configurations](dist/assets/configurations); |
| 38 | - charging station RFID tags lists: [src/assets](src/assets). |
| 39 | |
| 40 | 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). |
| 41 | |
| 42 | All charging station configuration templates are in the directory [src/assets/station-templates](src/assets/station-templates). |
| 43 | |
| 44 | A list of RFID tags must be defined for the automatic transaction generator with a default location and name: `src/assets/authorization-tags.json`. A template file is available at [src/assets/authorization-tags-template.json](src/assets/authorization-tags-template.json). |
| 45 | |
| 46 | **Configuration files hierarchy and priority**: |
| 47 | |
| 48 | 1. charging station configuration: [dist/assets/configurations](dist/assets/configurations); |
| 49 | 2. charging station configuration template: [src/assets/station-templates](src/assets/station-templates); |
| 50 | 3. charging stations simulator configuration: [src/assets/config.json](src/assets/config.json). |
| 51 | |
| 52 | The charging stations simulator have an automatic configuration files reload feature at change for: |
| 53 | |
| 54 | - charging stations simulator configuration; |
| 55 | - charging station configuration templates; |
| 56 | - charging station authorization RFID tags lists. |
| 57 | |
| 58 | But the modifications to test have to be done to the files in the build result directory [dist/assets](dist/assets). Once the modifications are finished, they have to be reported or copied to the matching files in the build source directory [src/assets](src/assets) to ensure they will be taken into account at next build. |

| 226 | ### Charging station configuration |
| 227 | |
| 228 | **dist/assets/configurations/\<hashId\>.json**: |
| 229 | |
| 230 | The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent. |
| 231 | |
| 232 | 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. |
| 233 | |
| 234 | #### stationInfo section |
| 235 | |
| 236 | The syntax is similar to charging station configuration template with some added fields like the charging station id (name) and the 'Configuration' section removed. |
| 237 | |
| 238 | #### configurationKey section |
| 239 | |
| 240 | The syntax is similar to the charging station configuration template 'Configuration' section. |
| 241 | |
| 242 | ## Start |
| 243 | |
| 244 | To start the program, run: `npm start`. |
| 245 | |
| 246 | To start the program with a UI controller, run: `npm start:server`. |
| 247 | Then, start/stop the simulator by going to `https://<hostname:port>` in a browser. Localhost port will default to 8080. For Cloud Foundry, the port is assigned based on the `process.env.PORT` environment variable. |
| 248 | |
| 249 | ## Docker |
| 250 | |
| 251 | In the [docker](./docker) folder: |
| 252 | |
| 253 | ```bash |
| 254 | make |
| 255 | ``` |
| 256 | |
| 257 | Or with the optional git submodules: |
| 258 | |
| 259 | ```bash |
| 260 | make SUBMODULES_INIT=true |
| 261 | ``` |
| 262 | |
| 263 | ## OCPP-J commands supported |
