Simple node.js program to simulate a set of charging stations based on the OCPP-J 1.6 protocol.

All configuration files are in the JSON standard format.

The program's global configuration parameters must be within the src/assets/config.json file. A configuration template file is available at src/assets/config-template.json.

All charging station templates are in the directory src/assets/station-templates.

A list of RFID tags must be defined for the automatic transaction generator with the default location and name src/assets/authorization-tags.json. A template file is available at src/assets/authorization-tags-template.json.

src/assets/config.json:

• workerSet: Worker set executing each a static number (chargingStationsPerWorker) of simulated charging stations from the total

• staticPool: Statically sized worker pool executing a static total number of simulated charging stations

• dynamicPool: Dynamically sized worker pool executing a static total number of simulated charging stations

To start the program, run: npm start.

In the docker folder:

make

Or without the optional git submodules:
