METHOD FOR SUPPLYING POWER TO UNMANNED AERIAL VEHICLE SYSTEM, SYSTEM FOR SUPPLYING POWER TO UNMANNED AERIAL VEHICLE, AND UNMANNED AERIAL VEHICLE SYSTEM
A method for supplying power to an unmanned aerial vehicle system comprises: performing judgment according to voltages of two rechargeable cells, and supplying, according to the judgment result, power to an unmanned aerial vehicle system by using at least one of a first rechargeable cell, a second rechargeable cell and a solar cell; the solar cell charges the first rechargeable cell or the second rechargeable cell. Further, to avoid crash of an unmanned aerial vehicle, the speed of the unmanned aerial vehicle system is reduced and the unmanned aerial vehicle system is landed after the electric quantities of the two rechargeable cells decrease to a threshold. Moreover, to avoid that the rechargeable cells are overcharged, charging of the rechargeable cells is stopped after the electric quantities of the rechargeable cells reach a threshold. Correspondingly, provided are a system for supplying power to an unmanned aerial vehicle, and the unmanned aerial vehicle system. In the power supply method and the system
