A conversion device (100) for an electric vehicle (800) has a battery interface for connecting the conversion device (100) to an on-board battery and a bidirectional inverter (112) having a first port and a second port for connecting the inverter (112) to the battery interface. An inverter (112) converts a DC voltage applied at the first port into an AC voltage and supplies the AC voltage to the second port. The switching device (100) has a switching device (118) having a switching port for connecting the switching device (118) to the second port, a drive interface (122) for connecting the switching device (100) to the drive motor, and an additional interface (124) for connecting the switching device (100) to the additional motor. The switching device (118) is configured to connect the switching port to the driver interface (122) or the additional interface (124) by using a switching signal (125).
