| 摘要 |
The invention relates to a power supply device for an electrically operable vehicle having an electric drive motor (1000), said power supply device comprises an electric energy accumulator device (1), a range-extender (10, 13) with an internal combustion engine (10) and a generator producing alternating current. Said generator (13) can be or is mechanically coupled to the internal combustion engine (10) and the energy accumulator device (1) can be charged during driving with the alternating current from the generator (13). Said energy accumulator device (1) comprises several power supply connections (1001, 1002, 1003) on which respectively one of several controllable potentials can be provided, and several power supply branches (100, 200, 300, 400, 500, 600) having several serially connected power cell modules (100-1 bis 600-n). Several power supply branches (100, 200, 300, 400, 500, 600) are interconnected on one end to the neutral point (123, 456) and each power supply connection (1001, 1002, 1003) is connected or can be connected to one end of a power supply branch (100, 200, 300, 400, 500, 600). |
