The invention relates to a power management module and method for an unmanned aerial vehicle, and the module comprises a power input end, a mechanical switch, an electronic switch module, an auxiliary source module, an auxiliary module, a load power distribution module and a power output end, the mechanical switch is disposed at the power input end, and the auxiliary source module comprises an auxiliary source voltage conversion module. The auxiliary module comprises a filter circuit, a triode and an optocoupler, when the mechanical switch is closed, the rear end voltage of the mechanical switch is connected to the input positive end of the auxiliary source to supply power to the auxiliary source module, and when the auxiliary source module is powered on, the output voltage of the auxiliary source module is loaded between the grid electrode and the source electrode of the electronic switch to enable the electronic switch to be closed and input and output to be connected to achieve power distribution. The beneficial effects are that the power distribution function is realized by combining the mechanical switch and the electronic switch, the extremely low discharge rate can be realized in the standby storage state, the filter circuit can eliminate the high-frequency jitter at the moment when the mechanical switch is powered on, and the optical coupler and the triode can realize the rapid cut-off of the input and output of the power supply.

本发明涉及一种无人机用电源管理模块及方法，包括电源输入端、机械开关、电子开关模块、辅源模块、辅助模块、载荷配电模块和电源输出端，所述机械开关设置于所述电源输入端，所述辅源模块包括辅源电压转换模块，所述辅助模块包括滤波电路、三极管和光耦，当机械开关闭合时，机械开关后端电压连接到辅源输入正端，给辅源模块供电，当辅源模块上电时，其输出电压加载到电子开关栅极、源极间，使电子开关闭合，输入输出接通，实现配电。其有益效果为：采用机械开关和电子开关相结合的方式实现配电功能，在待机存储状态下，可实现极低的放电率，滤波电路可消除机械开关上电瞬间的高频抖动，光耦和三极管可实现电源输入输出的快速切断。
