The invention provides an electric automobile power distribution system and an electric automobile, the electric automobile power distribution system comprises a battery pack module and a low-voltage component module, the battery pack module comprises a first power supply module and a second power supply module which are respectively composed of a plurality of battery cells, and the low-voltage component module comprises a VCU vehicle control unit connected with the first power supply module. And the second power supply module is connected with the DC/DC control module. According to the power distribution system of the electric vehicle, part of the battery cells in the battery pack module form the first power supply module to replace a low-voltage storage battery in the prior art, equivalently, the low-voltage storage battery is integrated into an original high-voltage battery pack, so that the manufacturing and assembling complexity and the production cost are reduced, and the production efficiency is improved. The low-voltage storage battery does not need to be replaced in the whole life cycle, and light weight of the whole vehicle is facilitated; meanwhile, under special circumstances, the low-voltage storage battery can be connected to a high-voltage battery of the whole vehicle in series to participate in power input.
本发明提供一种电动汽车配电系统及电动汽车,该电动汽车配电系统包括电池包模块及低压元器件模块,电池包模块包括分别由若干个电芯组成的第一供电模块及第二供电模块,低压元器件模块包括与第一供电模块连接的VCU整车控制器,第二供电模块连接DC/DC控制模块。本发明中的电动汽车配电系统,通过将电池包模块中的部分电芯组成第一供电模块,代替现有技术中的低压蓄电池,相当于将低压蓄电池集成到原有的高压电池包中,降低制造装配复杂度及生产成本的同时,做到全生命周期不用更换低压蓄电池,且利于整车轻量化;同时,特殊情况下,此低压蓄电池,可串联至整车高压电池中,参与动力输入。
