  • High-voltage charging arrangement for an electric vehicle, and a method for charging a traction battery
    Patent number: 11975618
    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).
