Charging Station Simulator

With the Battery Simulator , MOSAIC Extended offers advanced simulation for the processes of discharging and recuperation. For holistic scenarios, the Charging Station Simulator extends the modeling characteristics of electric vehicles as it validates charging requests from vehicles to control re-charging. An overview of how the simulators interact (and the used interactions) can be seen below.

Overview

Overview of Battery & Charging Station Simulator interaction

As can be seen from the interaction-chart above, the Charging Station Simulator is receiving and processing the VehicleChargingStartRequest-interactions. This involves checking if requested charging stations have available spaces, the vehicle is in charging range and some additional constraints. Furthermore, if a vehicle moves out of charging range or is removed from simulation it will automatically stop being charged. If a VehicleChargingStartRequest is successfully validated, a BatteryChargingStart-interaction is forwarded to the Battery simulator. Additionally, whenever a charging station is updated (vehicle un-/docked) the ambassador sends a ChargingStationUpdate-interaction to all subscribed simulators.

Configuration

The configuration of actual charging stations happens in the Mapping configuration . The only parameter configured in the charging_config.json is a global parameter for the maximum range of a charging station. This allows for abstract modeling of charging stations, without the need of being super accurate with the stop positions of vehicles.

Example configuration

{
    "chargingStationRange": "20m"
}
