1. A power supply device (1) for an electrical energy consumer unit (2) that is to be supplied with electrical energy and being arranged on a commercial vehicle trailer, the power supply device (1) comprising:

  • an electro-hybrid drive system (3) of a commercial vehicle, comprising a high-voltage battery (5) and a high-voltage system (4) having an inverter (6);

    the inverter (6) of the high-voltage system being electrically connected to the high-voltage battery (5) and an electric motor (7) of the commercial vehicle, such that the inverter (6) of the high-voltage system delivers energy from the high-voltage battery (5) to the electric motor (7);

    the electro-hybrid drive system (3) being directly connected to a supply unit (8) by a plug-in connection (14) for converting a direct voltage, from the high-voltage system (4) of the electro-hybrid drive system (3), into a three-phase alternating voltage;

    the supply unit (8) comprising a supply unit inverter (10), a transformer (12) and an output (11), the transformer (12) being connected downstream from the supply unit inverter (10) and the output (11) being connected downstream from the transformer (12) for transmitting the three-phase alternating voltage and supplying power to the consumer unit (2);

    the transformer (12) is a step up transformer; and

    the output (11) is a standardized interface (13) together with the consumer unit (2).
