The invention discloses an automobile high-voltage power supply circuit, an automobile and an automobile power supply control method. The automobile high-voltage power supply circuit comprises a powerbattery which comprises a positive electrode and a negative electrode, a fuse with one end electrically connected with the positive electrode of the power battery, and at least two circuits to be protected, wherein one end of each circuit to be protected is electrically connected with the other end of the fuse, and the other end of each circuit to be protected is electrically connected with the negative electrode of the power battery. When the power battery breaks down, the fuse can be fused in time, so that all the circuits to be protected in the automobile high-voltage power supply circuitare disconnected with the power battery, the circuits to be protected are prevented from being damaged, and the operation safety of the automobile is improved.

    本发明公开了一种汽车高压供电电路、汽车和汽车供电的控制方法,所述汽车高压供电电路包括:动力电池,包括正极和负极;熔断器,所述熔断器的一端与所述动力电池的正极电连接;至少两个待保护电路,所述待保护电路的一端与所述熔断器的另一端电连接,所述待保护电路的另一端与所述动力电池的负极电连接。当动力电池出现故障时,熔断器可及时的熔断,从而将汽车高压供电电路中所有的待保护电路均与动力电池断开连接,避免待保护电路受损,提高了汽车的运行安全性。
