A power supply circuit, an energy storage device and an unmanned aerial vehicle, the power supply circuit comprises a first power supply loop and a second power supply loop, and the first power supply loop is used for providing a first output current for a load based on electric energy provided by a power supply and stopping outputting the first output current when the first output current is greater than a first preset threshold. The second power supply loop is switched on or off based on the first output current; the conduction impedance of the second power supply loop is smaller than that of the first power supply loop; and the second power supply loop is also used for providing a second output current for the load based on the electric energy provided by the power supply when the second power supply loop is switched on, and is switched off when the second output current is greater than a second preset threshold. The first power supply loop and the second power supply loop both have the function of automatic power off when the current is too large, certain short circuit protection is achieved, and meanwhile, by providing the first output current and the second output current for the load, accidents such as fire and explosion caused by the fact that the too large current is output when short circuit occurs at the initial stage of power supply can be avoided.

    一种供电电路、储能设备及无人机,供电电路包括第一供电回路和第二供电回路,第一供电回路用于基于电源提供的电能向负载提供第一输出电流,并在第一输出电流大于第一预设阈值时停止输出第一输出电流。第二供电回路用于基于第一输出电流导通或关断;第二供电回路的导通阻抗小于第一供电回路的导通阻抗;第二供电回路还用于在导通时,基于电源提供的电能向负载提供第二输出电流,并在第二输出电流大于第二预设阈值时关断。第一供电回路和第二供电回路都具有当电流过大时自动断电的功能,实现一定的短路保护,同时,通过向负载分别提供第一输出电流和第二输出电流,可以避免在供电初期发生短路时,输出过大的电流,导致出现起火、爆炸等意外事故。
