Abstract

本发明公开了一种氢动力无人机的能量管理方法,属于燃料电池与锂电池混动动力系统技术领域。包括如下步骤:DC1控制过程:当燃料电池的输出功率Pfc小于设定输出功率Pfcset时,调节增大DC1模块的限流值,使燃料电池的输出功率增大;当燃料电池的输出功率Pfc大于设定输出功率Pfcset时,减小DC1模块的限流值,降低燃料电池的输出功率;DC2控制过程:当设定输出功率Pfcset小于无人机功率需求Pw时,锂电池进行功率的补充,DC2模块关闭;当设定输出功率Pfcset大于无人机功率需求Pw时,锂电池不放电工作,DC2模块开启,设置DC2模块的输出电压Vdc2等于锂电池开路电压Voc。本技术方案用以自动调节控制电堆的输出功率,以匹配无人机在不同工况下的有效能量分配。
