A drive train for a mixer drum comprises a generator which outputs a first alternating voltage to a first converter. The first converter is connected to a high-voltage direct voltage network. A second converter is also provided which is connected to the high-voltage direct voltage network and which supplies an electric motor with a second alternating voltage in order to drive the mixer drum. The drive train also comprises a high-voltage battery which is connected to the high-voltage direct voltage network. Finally, a control unit is also provided which is connected to the first and second power converters or the battery and thus controls a flow of energy via the high-voltage direct voltage network.
