The invention provides a hydrogen fuel cell power supply system for an unmanned aerial vehicle and a control method thereof, aiming at the long-endurance power supply requirement of an electric unmanned aerial vehicle, a set of hydrogen module, a fuel cell module and an electric power conversion module are added on the basis of an original unmanned aerial vehicle power battery to form a set of hybrid power supply system; the voltage of the lithium battery collected by the flight control module and the in-bottle pressure of the hydrogen module are used for sending an operation command to the electronic speed controller and sending commands such as starting, loading, rated power operation, load reduction or shutdown to the fuel cell module, and the cruising ability of the unmanned aerial vehicle is greatly improved under the condition that the extra load of the unmanned aerial vehicle is not increased too much.
本发明提供一种无人机用氢燃料电池电源系统及其控制方法,针对电动无人机的长续航电源需求,在原有无人机动力电池的上增加一套氢气模块、燃料电池模块和电力转换模块,组成一套混合电源系统,利用飞控模块采集的锂电池的电压和氢气模块的瓶内压力对电调发送运行命令和对燃料电池模块发出启动、加载、额定功率运行、降载或停机等命令,在不过多增加无人机额外的载重条件下,大大提升了无人机的续航能力。
