The invention discloses an electric vehicle and a power supply circuit thereof, and belongs to the field of electric vehicles. The control circuit can dynamically adjust the voltage of the battery pack based on the charging voltage provided by the charging piles, so that the charging piles with different charging voltages can charge a plurality of batteries in the battery pack. Compared with the prior art, a charging pile matched with the voltage of the high-voltage battery needs to be adopted to charge the high-voltage battery, and the power supply circuit provided by the embodiment of the invention effectively improves the flexibility of charging the plurality of batteries in the battery pack.

    本申请公开了一种电动车辆及其电源电路,属于电动车辆领域。由于控制电路可以基于充电桩提供的充电电压的大小动态调整电池包的电压,以使得不同充电电压的充电桩均可以为电池包中的多个电池充电。相较于相关技术,需要采用与该高压电池的电压相匹配的充电桩为高压电池充电,本公开实施例提供的电源电路有效提高了对电池包中多个电池充电的灵活性。
