In this case, the wallboxes in the charging group have communication interfaces allowing connection to an intelligent energy management system. This controls all system inflows and outflows and directs the group. Accordingly, either each charging station individually or the charging group as a whole can be control by the EMS.
To model this use case, you will need an energy manager with which you are able to communicate via Modbus or EEBus. Control of the load management takes place via the energy management system. For configuration of the Modbus TCP connection please refer to the Energy Management Support Area and the use case: "Connection to an energy management system via Modbus" or "Connection to an energy management system via EEBus".
