The invention provides a power supply circuit and a power supply method. The power supply circuit comprises a main power supply module, a storage battery power supply module, a power supply controller, a control switch, a first power supply output channel, and a second power supply output channel, wherein the main power supply module, the storage battery power supply module, the first power supply output channel and the second power supply output channel are mutually connected through control switches, the power supply controller controls the on-off states of the control switches, and the first power supply output channel and the second power supply output channel respectively supply power to different loads with mutually redundant functions. By means of the power supply circuit, two power supply output channels, namely two single points, can be formed; and when one single point breaks down, the power supply controller can control the control switches to be switched off, and at the moment, the other power supply output channel still supplies power to loads with redundant functions, so safe operation of a vehicle can be guaranteed.

    本发明提供了一种供电电路及供电方法,供电电路包括主电源供电模块、蓄电池供电模块、供电控制器、控制开关、第一供电输出通道和第二供电输出通道,所述主电源供电模块、所述蓄电池供电模块、所述第一供电输出通道与所述第二供电输出通道通过控制开关相互连接,通过所述供电控制器控制控制开关的通断,所述第一供电输出通道与所述第二供电通分别为功能相互冗余的不同负载供电。通过上述供电电路,可以形成两条供电输出通道,即两个单点,在其中一个单点故障时,可以通过所述供电控制器控制控制开关的断开,此时仍有另一供电输出通道为功能相互冗余的负载供电,进而也可以保证车辆的安全运行。
