The invention provides a power supply circuit and a power supply method. The power supply circuit comprises a battery pack, a switching circuit, a detection circuit, a first control circuit and a second control circuit. The switching circuit is electrically connected between the battery pack and the power receiving equipment, the first control circuit is used for outputting a first control signal to control the switching circuit to be switched on when the vehicle is in a first state, so that the battery pack provides power for the power receiving equipment, and the detection circuit is used for detecting whether the first control circuit normally outputs the first control signal or not; under the condition that the first control circuit does not output the first control signal normally, a trigger signal is output to the second control circuit, and the second control circuit outputs a second control signal based on the trigger signal so as to control the switch circuit to maintain conduction. By means of the power supply circuit, a dual control mechanism is formed through the first control circuit and the second control circuit, and stable power supply of the power receiving equipment on the vehicle can be guaranteed.

    本申请提供一种供电电路及供电方法,供电电路包括电池组、开关电路、侦测电路、第一控制电路及第二控制电路。开关电路电连接于电池组与受电设备之间,第一控制电路用于在车辆处于第一状态的情形下,输出第一控制信号,以控制开关电路导通,使得电池组向受电设备提供电力,侦测电路用于侦测第一控制电路是否正常输出第一控制信号,及在侦测到第一控制电路未正常输出第一控制信号的情形下,输出触发信号至第二控制电路,第二控制电路基于触发信号,输出第二控制信号,以控制开关电路维持导通。利用上述的供电电路,通过第一控制电路与第二控制电路构成双重控制机制,可保障车上的受电设备的稳定供电。
