Analysis Of Power Source Of Multirotor Uavs

Multirotor unmanned aerial vehicles (UAVs) have found wide applications in practice with the rapid development of multirotor UAV technology. But limited by the energy density of conventional Li batteries, the battery life is short, which has become a bottleneck restricting the development of multirotor UAVs. Therefore, the power source of multirotor UAVs is urging to be improved. This paper introduces the application of fuel cell, fuel power, solar cell and hybrid power in multirotor UAVs and some innovative technologies of lithium-ion battery in recent years and also looks forward to the future development of various power sources of multirotor UAVs.
