METHOD FOR PERFORMING A JUMP STARTING OPERATION OR A REMOTE CHARGING OPERATION OF VEHICLES

摘要

A method for performing a jump starting operation or a remote charging operation of a recipient vehicle. A current path from an inverter to an electric drive of the donor vehicle is disconnected. For the jump starting operation, the inverter of the donor vehicle is connected on the output side to the electric drive of the recipient vehicle and the inverter of the donor vehicle is operated in the virtual driving operation mode and the electric drive of the recipient vehicle is started. During the remote charging operation, the inverter of the donor vehicle is connected on the output side to the inverter of the recipient vehicle and is operated in the virtual driving operation mode, while the inverter of the recipient vehicle is operated in the virtual recuperation operation mode and charges the discharged battery of the recipient vehicle.
