Abstract: The invention essentially relates to a facility for charge current control of storage units in an electrical energy supply grid including, among others, distributed generators and distributed storage units, in which a logic unit is present such that, a storage charge current value can be determined for the storage unit as a function of control variables transferred via a communication system of measurement variables determined at the storage and of locally held internal control variables. This represents an important component for achieving the optimum possible overall utilization of the distributed and multiple-use energy storage.

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: A method establishes an IP-based communications connection between an electric vehicle and a charge control unit associated with a charging station assigned an IP address. The electric vehicle is connected to the charging station via a charging cable and/or an inductive charge coupling for charging and/or discharging. A first communication connection that can be used exclusively by the electric vehicle and the charging station is provided via the charging cable and/or the inductive charging coupling. The electric vehicle having the charging control unit and the charging infrastructure can communicate via a second communications connection that can be used in parallel by other electric vehicles and charge control units. An identification is provided to the electric vehicle and the charging control unit. An IP-based communication is established between the electric vehicle and the charging control unit, using the IP address.
