The invention provides a vehicle distributed driving system, a vehicle charging system and a vehicle, the vehicle distributed driving system comprises a high-voltage battery, an inverter circuit and four driving motors used for driving hubs, the high-voltage battery comprises a battery positive electrode and a battery negative electrode, and the inverter circuit comprises a battery positive electrode and a battery negative electrode; a midpoint wiring port is formed in the midpoint between the battery positive electrode and the battery negative electrode, and one pair of driving motors located at the diagonal position are electrically connected with the battery positive electrode and the midpoint wiring port through the inverter circuit. And the other pair of driving motors at the diagonal position is electrically connected with the negative electrode of the battery and the midpoint wiring port through the inverter circuit. According to the invention, on the premise of high battery charging power during charging, the high-voltage charging pile can be used for charging the high-voltage battery, the low-voltage charging pile can also be used for charging the high-voltage battery, the compatibility is improved, the high-voltage battery can use the low-voltage power module, a silicon carbide module does not need to be used, and the cost is reduced.

    本发明提供一种车辆分布式驱动系统、车辆充电系统及车辆,车辆分布式驱动系统包括高压电池、逆变电路、和四个用于驱动轮毂的驱动电机,所述高压电池包括电池正极和电池负极,所述电池正极与所述电池负极之间的中点处设有中点接线端口,位于对角线位置的其中一对所述驱动电机通过所述逆变电路与所述电池正极和所述中点接线端口电连接,位于对角线位置的另一对所述驱动电机通过所述逆变电路与所述电池负极和所述中点接线端口电连接。实施本发明,实现充电时在高电池充电功率的前提下,既可以用高压充电桩为高压电池充电,也可以用低压充电桩为高压电池充电,提高兼容性,并且使高压电池能够使用低压功率模块,无需使用碳化硅模块,降低成本。
