Abstract
The disclosure relates to a power supply device for an electrically operable vehicle having an electric drive motor. The power supply device comprises an electric energy accumulator device, a range-extender with an internal combustion engine and a generator producing alternating current. The generator is mechanically connectable to the internal combustion engine, and the energy accumulator device is configured to be charged during driving with the alternating current from the generator. The energy accumulator device comprises several power supply connections on which respectively one of several controllable potentials can be provided, and several power supply branches having several serially connected power cell modules. Several power supply branches are interconnected on one end to the neutral point and each power supply connection is connectable to one end of a power supply branch.
