Title:
POWER SUPPLY METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/034148
Kind Code:
A1
Abstract:
A power supply method and device. The power supply method is applied to a host device (100). The host device comprises a power supply circuit. The power supply circuit comprises a first power supply circuit (130) and a second power supply circuit (140). The power supply method comprises: when it is detected that the host device (100) is connected to an external device (200) by means of a connector (110), determining a maximum voltage value supported by the external device; and selecting the first power supply circuit or the second power supply circuit from the power supply circuit according to the maximum voltage value to supply power to the external device, a supply voltage value of the first power supply circuit being greater than that of the second power supply circuit. Hence, this solution can supply power to external devices of different power requirements, and can ensure the safety of power supply. Moreover, also provided are an unmanned aerial vehicle and a computer-readable storage medium.
