The invention discloses a combined power supply device, method and system for an electric unmanned aerial vehicle. The method comprises the steps of obtaining a power demand signal of an unmanned aerial vehicle; judging whether the demand power is greater than the rated output power of the metal-air battery according to the power demand signal to obtain a first judgment result; if the first judgment result shows that the first judgment result is positive, obtaining the residual electric quantity of the super-capacitor; judging whether the residual electric quantity of the super-capacitor is greater than a capacitor electric quantity minimum threshold to obtain a second judgment result; if the second judgment result is positive, sending a control signal for controlling the super capacitor to discharge to a super capacitor charging management module; if the second judgment result shows no, sending out an insufficient power alarm signal; and if not, controlling the metal-air battery to output power according to the power demand signal. According to the combined power supply device, method and system for the electric unmanned aerial vehicle, the instantaneous high-power requirement of the unmanned aerial vehicle can be met.

    本发明公开一种电动无人机组合供电装置、方法及系统。该方法包括:获取无人机的功率需求信号;根据功率需求信号判断需求功率是否大于金属空气电池的额定输出功率,得到第一判断结果;若第一判断结果表示是,则获取超级电容的剩余电量;判断超级电容的剩余电量是否大于电容电量最低阈值,得到第二判断结果;若第二判断结果表示是,则向超级电容充电管理模块发出控制超级电容放电的控制信号;若第二判断结果表示否,则发出功率不足告警信号;若第一判断结果表示否,则控制金属空气电池按照功率需求信号输出功率。本发明的电动无人机组合供电装置、方法及系统,能够满足无人机瞬时大功率的需求。
