METHOD AND SYSTEM FOR COMMUNICATION BETWEEN A VEHICLE AND A CHARGING STATION FOR UNLOCKING MECHANICAL CHARGING CABLE COUPLING

摘要

A method for communicating between an electric vehicle and a charging station for electrically charging at least one energy storage device of the electric vehicle. The electric vehicle is connected to the charging station during the charging process by a lockable mechanical coupling between a terminal of charging cable connected to the vehicle and a terminal of the charging station. Charging current is fed from the charging station through the charging cable. Information is transferred in the course of the charging process based on a communication between the electric vehicle and the charging station. The information includes a signal transmitted from the electric vehicle to the charging station for locking and/or unlocking the mechanical coupling. The signal triggers the locking and/or unlocking of the mechanical coupling between the terminal of the charging cable and the terminal at the charging station.

1. A communication method between an electric vehicle and a charging station,
wherein, during a charging operation for electrically charging the electric vehicle, the electric vehicle is connected to the charging station via a lockable mechanical coupling between a terminal of a charging cable connected to the electric vehicle and a terminal of the charging station, and charging current is supplied from the charging station to at least one energy storage device of the electric vehicle through the charging cable, the method comprising: transmitting information over a course of the charging operation for communication between the electric vehicle and the charging station; thereby transmitting a signal from the electric vehicle to the charging station for unlocking the mechanical coupling, to thereby trigger in the charging station an unlocking of the mechanical coupling between the terminal of the charging cable and the terminal of the charging station via the signal.
