The embodiment of the invention discloses a power supply system, a power supply method thereof and a vehicle, at least two power supply branches are arranged, under the condition that at least one switch module is switched on, a power supply can supply power to a load through the switch module, and dual-power-supply or multi-power-supply power supply is achieved. A corresponding redundant module does not need to be arranged for each circuit module in the power supply system, so that the circuit scale and cost of the power supply system are reduced. The power supply system further comprises a detection module and a control module, a voltage signal and/or a current signal in the power supply system are/is detected through the detection module, and after the control module sends a conduction control signal to the switch module, whether the switch module is normally conducted or not is determined based on the voltage signal and/or the current signal, and then whether the switch module works normally or not is determined. When power is supplied to the load, the switch module capable of working normally can be controlled to be switched on to supply power to the load, so that the power supply reliability is ensured.
本发明实施例公开了一种供电系统及其供电方法、车辆,通过设置至少两路供电支路,在至少一个开关模块导通的情况下,电源可以通过开关模块为负载供电,实现双电源供电或多电源供电。供电系统中无需针对每一电路模块设置对应的冗余模块,使得供电系统的电路规模和成本降低。供电系统还包括检测模块和控制模块,通过检测模块检测供电系统中的电压信号和/或电流信号,控制模块在向开关模块发送导通控制信号后,基于电压信号和/或电流信号确定开关模块是否正常导通,进而确定开关模块是否正常工作。在向负载供电时,可以控制能够正常工作的开关模块导通为负载供电,进而保证供电可靠性。
