Abstract:
1. A method for detecting a state of a connection between a charging station and an electrically driven motor vehicle that has a power line communication chip and a vehicle-side control pilot line, the method comprising: plugging a power line of the charging station into the motor vehicle to connect the vehicle-side control pilot line to a control pilot line of the charging station; using the power line communication chip of the motor vehicle to measure a length of the control pilot line between the motor vehicle and the charging station by transmitting a signal from the PLC chip along the CP line between the motor vehicle and the charging station and receiving the signal reflected at the end of the CP line between the motor vehicle and the charging station and run back to the PLC chip, wherein the length of the distance that the signal travels is determined based on the signal transit time; and determining a specific type of cable based on of the length of the CP line between the motor vehicle and the charging station.
