Abstract: A charging adapter for electrically connecting a motor vehicle to a charging device, includes a temperature sensor and a modulator. The charging adapter is configured to be electrically connected to a first connection element and to a second connection element simultaneously. The first and second connection elements are not electrically connectable to each other. The charging adapter is configured to simultaneously transmit a transmission signal via a first cable element and a charging current via a second cable element from the charging device to the motor vehicle. The temperature sensor is configured to determine a temperature of the charging adapter and transmit the temperature to the modulator. The modulator is configured to modulate a modulation signal to a transmission signal. The modulation signal includes an indication of the temperature.

Abstract: A method for vehicle charging according to an adapter specification, the method including arranging a charging plug adapter in a transition between a charging plug and a charging connection of a vehicle and storing a profile dependent on at least one transition resistor of the adapter, which has charging current limits as a function of a charging time, in a charging file on a storage medium of a controller of the vehicle along with a specification of the adapter. The method further includes transmitting a code from the plug to the controller via a line between an auxiliary contact of the plug and the vehicle before a charging process to identify the adapter. The method further includes detecting the specification of the adapter with the controller using the code and reading the profile from the file using the detected specification and performing the charging process according to the profile.

Abstract: A high-voltage charging arrangement (2) is provided for charging a traction battery (20) of an electric vehicle at a DC charging station (4). The DC charging station (4) has a first voltage (Vin) and the traction battery (20) has a second voltage (Vout). At least one DC-DC converter (10) has a first conduction path (12) with a converter (16) for transforming the first voltage (Vin) into the second voltage (Vout) and a second conduction path (14) has a bypass (18) for bypassing the converter (16). A control device (26) communicates with the DC charging station (4) is possible. An input element (28) is provided for selecting a conduction path (12, 14) and is connected to the control device (26) for control purposes. A method also is provided for performing a charging process for a traction battery (20) of an electric vehicle at a DC charging station (4).
