The invention discloses a power supply circuit, a corresponding control method thereof and a vehicle. The protection element and the current adjusting circuit are arranged in the power supply circuit, when adhesion of the high-voltage contactor is detected, the current adjusting circuit is controlled to work so as to adjust the current flowing through the protection element, and then output of the battery pack is cut off. Therefore, when the high-voltage contactor cannot be turned off due to adhesion, the electric connection between the battery pack and the electric equipment can be cut off, the vehicle can be maintained in time, and the use safety of the vehicle is improved.

    公开了一种供电电路及其对应的控制方法和车辆。通过在供电电路中设置保护元件和电流调节电路,在检测到高压接触器粘连时,控制电流调节电路工作,以调节流过保护元件的电流,进而断开电池包的输出。由此,可以在由于高压接触器粘连无法关断时,切断电池包与用电设备之间的电连接,可以及时对车辆进行维护,提高车辆使用的安全性。
