EV chargers simulator

This simulator emulates ChargePoint web API for accessing EV chargers. At the current stage it works only in "replay" mode:

• Load historical data from excel or json files
• Reply these data via the ChargePoint APIs:
• GetCPNInstances
• GetStationGroups
• GetStations
• GetLoad

Running the simulator:

1. Read the data from excel file and serve them:

   go run main.go --file <excel file with recorded charging data>
   

2. Read the data from json files and serve them:

   go run main.go --dir <directory with json files with recorded charging data>
   

3. Generate random data, based on configuration parameters defined in a json file :

   go run main.go --rand <json file with configuration parameters>
   

   There is a sample file with configuration parameters for the random generator res/grand.json :

   maxCPNs - generate up to maxCPNs ChargePoint Networks

   maxFacilities - generate up to maxFacilities charging facilities

   maxChargeGroups - generate up to maxChargeGroups charging groups in each facility

   maxChargeStations - generate up to maxChargeStations charging stations in each group

   maxChargePorts - generate up to maxChargePorts charging ports in each station

   maxVehicleBattery - the maximum capacity of a electric vehicle battery. Generated vehicles have battery with random capacity in the interval [maxVehicleBattery/2, maxVehicleBattery]

   RandomSeed - Random seed to be used, to reporduce the same random generated numbers

   CPNs - generate CPNs count of ChargePoint Networks

   Facilities - generate Facilities count of ChargePoint facilities

   ChargeGroups - generate ChargeGroups count of charging groups in each facility

   ChargeStations - generate ChargeStations count of charging stations in each group

   ChargePorts - generate ChargePorts count of charging ports in each station

   PortLoad - probability of a port to have a charging session, in %

   both exact and max numbers can be specified, in this case max numbers have a higher priority.
