Abstract
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.

16. 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 locking or unlocking the mechanical coupling, to thereby trigger in the charging station a locking or unlocking of the mechanical coupling between the terminal of the charging cable and the terminal of the charging station via the signal. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 29, 30, 31, 32)

28. A system for communication between an electric vehicle and a charging station for electrically charging at least one energy storage device of the electric vehicle, wherein the electric vehicle is connected, during a charging process, 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 in order to supply charging current through the charging cable from the charging station to the at least one energy storage device, the system comprising:
-
a first communication control unit for the electric vehicle; a second communication control unit for the charging station; with information being transmitted via the first and second communication control units during operation of the system over the course of a charging operation based on a communication between the electric vehicle and the charging station; said first and second communication control units being configured such that the information transmitted therebetween includes a signal, generated by said first communication control unit, for one of locking or unlocking the mechanical coupling; and wherein said second communication control unit is configured to trigger the locking or unlocking of the mechanical coupling between the terminal of the charging cable and the terminal of the charging station via the signal.
