Abstract: A charging device for a motor vehicle for electrically charging an energy storage of the motor vehicle. The charging device has a DC charging unit for conductive coupling to a DC charging plug, which includes a first and second connection pin and a first and second housing part with a respective housing wall which surrounds the respective connection pin and has a distance from the respective connection pin in the radial direction, whereby a respective insertion opening is provided between the connection pin and the housing part for inserting a respective contact element of the DC charging plug.

Abstract: A method for positioning an electric vehicle over a charging plate for inductive charging of a high-voltage storage device of an electric vehicle and to a device suitable for the method.

Abstract: A method for ascertaining positional data describing a position of a motor vehicle relative to a stationary charging device as a destination. At the charging device end, a plurality of electromagnetic transmission signals are emitted from respectively different transmitting positions that are arranged in a transmitting position pattern and have respectively at least one signal characteristic that can be differentiated by the motor vehicle during reception. After which, for each reception signal received, signal strength data that describe its reception strength are produced, and the positional data are determined from the data, taking into consideration transmitter information describing the transmitting position pattern and an assignment of the transmitting positions to the signal characteristics.

Abstract: An energy storage device for a motor vehicle. A housing and at least one energy storage device mounted in the housing. A coil device is provided, which is designed for inductively supplying energy via an external magnetic field in order to charge the energy storage, and which is arranged on an outer surface of the housing.
