Abstract: A system for positioning a vehicle at a charging station. The system comprises: a wireless communication arrangement comprising a first communication device configured to wirelessly communicate with a second communication device by a wireless protocol; a vehicle positioning arrangement comprising a transmitting antenna configured to transmit a detection signal, and a receiving antenna configured to receive the detection signal. The transmission of the detection signal by the transmitting antenna and/or the detection of the detection signal by the receiving antenna is controlled to determine an angle between the transmitting antenna and the receiving antenna, which angle is used to guide the vehicle to a predetermined position at the charging station. The first communication device comprises one of the transmitting antenna and receiving antenna of the vehicle positioning arrangement.

Abstract: A monitoring circuit for monitoring of a PE connection in a vehicle charging interface of a vehicle. The vehicle is at least partly electrically powered. The monitoring circuit is connected to a first line of a communication circuit. The monitoring circuit and the communication circuit are separate circuits. The monitoring circuit comprises a current source, a current measuring unit and the PE connection. The current source is adapted to generate a current running through the monitoring circuit. The current measuring unit is adapted to measure the current running through the monitoring circuit and thereby monitoring the PE connection.
