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.

Abstract: The present invention relates to methods and apparatuses for allocating amounts of energy for prosumers, wherein the prosumers provide minimum and maximum amounts of energy for a future interval of time and the respective amounts of energy from the prosumers are generated in such a manner that, on the one hand, a relative position of the amount of energy within an interval for the particular prosumer, as defined by the minimum amount of energy and the maximum amount of energy, assumes an identical value for all prosumers and, on the other hand, a sum of the amounts of energy from all prosumers produces a value of zero. The invention can be used in the distribution of amounts of energy in a power supply system having conventional energy producers and energy consumers as well as in novel participants in the power supply system which can both consume and provide energy, for example an electric vehicle.
