Schematic overview (load management)
Fleet solution
The KeContact M10 is the server for a group of Charging stations (KeContact P20 Wallboxes) with a com-
mon power line. KeContact M10 is the logical Charge Point.
After a power failure or the loss of the communication connection, an automatic restart is performed. After-
wards the running charging sessions are resumed.
Plug & Charge with ISO 15118
The ISO 15118 protocol allows an intelligent charging of an Electric Vehicle. The charging station informs the
vehicle when and at which price a certain energy amount is available. This data, the current battery level and
the programmed finishing time is the basis for the vehicle to determine a cost optimized charging procedure.
Basis functionality for charging
Vehicles that offer only a functionality for charging according IEC 61851-1 are also supported. The authoriza-
tion for charging can be carried out with a chip card (RFID).
