Abstract

A power supply device for a unit that is to be supplied with electrical energy and typically arranged on a commercial vehicle trailer, for example. The power supply device comprises an electro-hybrid drive system for a commercial vehicle and a supply unit which is designed to convert a direct voltage, from a high-voltage system of the electro-hybrid drive system, into a three-phase alternating voltage. The supply unit comprises an output which transmit the three-phase alternating voltage for supplying power to the unit. The output is designed to form a standardized interface together with the unit. In addition, the unit which can be connected to the power supply device is one of a refrigerator unit, a concrete mixer, a concrete pump or a shredder.
