Simultaneously, through designing into power module 120 and having multiple power supply mode, can also adopt other power supply modes to supply power for unmanned aerial vehicle 20 when a certain power supply mode goes wrong, can ensure charging device 10's smooth work, solve the not enough problem of unmanned aerial vehicle 20 duration.
The power supply module 120 may include a plurality of power supply units, which are arbitrarily combined to form a plurality of power supply modes. For example, the power supply module 120 may include two power supply units, and the two power supply units may form a power supply mode of separate power supply and common power supply. In the embodiment of the present application, the power supply module 120 includes three power supply units as an example for detailed description:
referring to fig. 2, the power supply module 120 includes a first power supply unit 121, a second power supply unit 122, and a third power supply unit 123.
