The invention provides power supply equipment, a vehicle and a power supply method thereof, the vehicle can comprise in-vehicle load equipment, a storage battery and the power supply equipment, and the power supply equipment comprises a DCDC circuit and a switch; wherein the output end of the DCDC circuit is coupled with one end of the switch and serves as a first power supply port of the power supply equipment, and the other end of the switch serves as a second power supply port of the power supply equipment; the first power supply port is used for being coupled with a first load in the in-vehicle load equipment, and the second power supply port is used for being coupled with a second load in the in-vehicle load equipment and the storage battery. By controlling the state of the switch, the important load can be ensured to be powered under any single fault of short circuit of load equipment in the vehicle, fault of a DCDC circuit and failure of a storage battery, the important low-voltage load of the whole vehicle can still ensure the reliability of backup power supply, the reliability of redundant power supply of the low-voltage load is improved, and the safety of the whole vehicle is ensured.

本申请提供一种供电设备、车辆及其供电方法，车辆可以包括：车内负载设备、蓄电池和供电设备，供电设备包括：DCDC电路和开关；其中，DCDC电路的输出端与开关的一端耦接且作为供电设备的第一供电端口，开关的另一端作为供电设备的第二供电端口；第一供电端口用于与车内负载设备中的第一负载耦接，第二供电端口用于分别与车内负载设备中的第二负载和蓄电池耦接。通过控制开关的状态，可以保障车内负载设备出现短路、DCDC电路出现故障、以及蓄电池故障失效中的任何单一故障下，重要负载都得到供电，整车重要低压负载仍然可以保证备份供电的可靠性，提升低压负载的冗余供电可靠性，保障了整车安全。
