Supply device for providing electrical energy to a consumer electrical circuit, containing a protection and monitoring device () assigned individually to the consumer, to the output of which the consumer electrical circuit can be connected via connecting means (), wherein the protection and monitoring device () has sensor means () for detecting at least one electrical quantity, and an analysis device () controlled by the sensor means (), which contains parameterization means for specifying in a predefinable manner at least one safety relevant triggering criterion, wherein on the at least one safety relevant triggering criterion being reached, a switching device () for the consumer electrical circuit can be controlled.

Device and method for providing a quantity of energy in said supply device for consumer

Charging cable plugfor electric vehicles, with a housingand electrical contacts, arranged in the housing, for connection to a charging station. For simple identification before a charging procedure, an identification meansis proposed, arranged in the housingand communicating with the charging stationvia the electrical contacts

Charging cable plug for electric vehicles

Charging station for electric vehicles. A network stabilization is achieved by a network frequency measuring devicebeing arranged to acquire a network frequency and to detect a network frequency which deviates from a reference frequency, and a load regulating devicebeing in operational connection with the network frequency devicesuch that, upon a deviation from the reference frequency being detected in the network frequency, the load regulating deviceregulates the electrical power emitted to an electric vehicle by the charging station

Charging station for electric vehicles with network stabilization

Method and device for controlling charging stations for electrical vehicles. In order to minimize peak power demands in at least two charging stationscombined into a group, actual charging parameters are exchangedwithin the charging stationswithin the group, a load prediction for the groupis createddepending on at least the actual charging parameters, and setpoint charging parameters for the charging stationsof the groupare determineddepending on the load prognosis.

Control of charging stations

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.

Charging cable connector for connecting an electric vehicle to a charging station

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.

Method and device for communication between an electric vehicle and a charging station

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.

Method and a device for charging electric vehicles

Charging cable locking device for electric vehicles with a receptacleon the vehicle side to receive a charging cablethat can be connected with a charging station, and a locking unitarranged at the receptacle, wherein the locking unitis arranged for locking and releasing the charging cablewith the receptacle. Secure charging is possible in that the locking unitis coupled with a closing unitof the vehicle such that on activation of the closing unit, the charging cablecan be locked with the receptacle, and that on deactivation of the closing unit, the charging cablecan be released from the receptacle
