Abstract: Charging station for electric vehicles. A network stabilization is achieved by a network frequency measuring device 8 being arranged to acquire a network frequency and to detect a network frequency which deviates from a reference frequency, and a load regulating device 10 being in operational connection with the network frequency device 8 such that, upon a deviation from the reference frequency being detected in the network frequency, the load regulating device 10 regulates the electrical power emitted to an electric vehicle by the charging station 2.

Abstract: Method and device for controlling charging stations for electrical vehicles. In order to minimize peak power demands in at least two charging stations 10 combined into a group 12, actual charging parameters are exchanged 32 within the charging stations 10 within the group 12, a load prediction for the group 12 is created 34 depending on at least the actual charging parameters, and setpoint charging parameters for the charging stations 10 of the group 12 are determined 38 depending on the load prognosis.

Abstract: The invention relates to a plug device for a charging cable for connecting an electric vehicle to a charging station, comprising a housing, electrical contacts associated with the housing for connecting to a connecting device in the charging station or in the electric vehicle, and a coding means arranged in the housing for the value of the amperage which may be transmitted via the charging cable. The invention further relates to a system consisting of a charging cable and a charging station and/or an electric vehicle as well as a charging cable equipped with the plug device.

Abstract: A method is described for communication with an electric vehicle, comprising a generating of a first predetermined DC voltage level on a pilot conductor, a recognition of the existence of an electrical connection to an electric vehicle by means of the detection of a second predetermined DC voltage level on the pilot conductor, a sending out of a trigger signal on the pilot conductor, a detection of a vehicle identification signal on the pilot conductor and an approval of the electricity supply on a power conductor.

Abstract: A method for charging electric vehicles through connecting an electric vehicle to a charging station for receiving electric energy. Different power supply offers can be selected particularly simple in that at least a state of charge of a battery and a desired duration of charge is determined in the vehicle, the energy required for fully charging the battery is determined in the vehicle, at least information concerning the required energy and the duration of charge is transmitted to the charging station by the vehicle and at least one power supply offer adapted to the information is received by the vehicle from the charging station which power supply offer has been determined from among a plurality of different power supply offers by means of the charging station using the information received.

Abstract: Charging cable locking device for electric vehicles with a receptacle 2 on the vehicle side to receive a charging cable 4 that can be connected with a charging station 20, and a locking unit 8 arranged at the receptacle 2, wherein the locking unit 8 is arranged for locking and releasing the charging cable 4 with the receptacle 2. Secure charging is possible in that the locking unit 8 is coupled with a closing unit 32 of the vehicle such that on activation of the closing unit 32, the charging cable 4 can be locked with the receptacle 2, and that on deactivation of the closing unit 32, the charging cable 4 can be released from the receptacle 2.
