The invention relates to a power supply system for an electric automobile and the electric automobile. The power supply system comprises a power battery (1) which comprises a plurality of battery cells (5) which are connected in series and/or in parallel, and a plurality of low-voltage electric elements distributed on the vehicle body, wherein a plurality of independent low-voltage power supply interfaces (6) are led out from the power battery (1), and a plurality of low-voltage electric elements are respectively and electrically connected to the corresponding low-voltage power supply interfaces nearby. Compared with an existing centralized power supply system, the distributed power supply system is advantaged in that a DC/DC converter can be omitted, the length of a power supply wire harness of the whole vehicle is greatly reduced, the cost of the whole vehicle is reduced, and power supply reliability is improved.
本发明涉及一种用于电动汽车的供电系统及电动汽车。所述供电系统包括:动力电池(1),所述动力电池包括彼此串联和/或并联的多个电芯(5);和分布于车身上的多个低压用电元件;在所述动力电池(1)上引出有多个独立的低压供电接口(6),所述多个低压用电元件分别就近地电连接到对应的低压供电接口。根据本发明的上述分布式供电系统与现有的集中式供电系统相比可省略DC/DC转换器并大幅降低整车供电线束的长度,从而降低整车成本,并提升供电可靠性。
