Charging interface module (LIM)

The process "charging" of a electric vehicle is equal to the process "refuelling" of a conventionally powered vehicle.

Since a charging cable is used, the process is also called conductive (grid-bound) charging.

The charging process requires both, components in the vehicle as well as components outside the vehicle. Inside the vehicle, a charging socket and a power electronics for the voltage conversion is necessary. Outside the vehicle, not only AC voltage supply and a charging cable but also a charging station (for example wallbox) is necessary. The wallbox has a protective function and carries out the control of the charging process.

The charging interface module (LIM) is the control unit with the task to enable the communication between the vehicle and the charging station.
