The invention relates to the technical field of wireless power transmission of unmanned aerial vehicles, in particular to an unmanned aerial vehicle charging method and system with an inversion switching-based identity recognition function. IDs of different charging ends can be defined through the switching frequency of the inverter circuit, different switching frequencies correspond to different ID information, and the method has the advantages of being high in accuracy, easy to detect and the like. Different switching frequencies correspond to different transmission electric energy values, the ID information of the charging end is transmitted to the unmanned aerial vehicle in an electric energy mode, that is, the electric energy is transmitted to the energy receiving coil through the energy transmitting coil, other extra equipment is not needed in the identity authentication process, the structure is simple, and the cost is saved. The unmanned aerial vehicle can identify the identity information of the charging end by detecting the received electric energy value, in the wireless electric energy transmission process, the electric energy transmission speed is high, the identity authentication speed is high, when the unmanned aerial vehicle receives the electric energy signal with the charging end ID information, the unmanned aerial vehicle can be in communication connection with the electric energy signal, the connection precision is high, and channel crosstalk does not exist.
