Document Type and Number:
WIPO Patent Application WO/2024/046109
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a charging method and an electric device. The present application relates to the technical field of electronics, and can charge the electric device by using a preset charging parameter when the charging protocol used by the electric device is switched, and matching the changed protocol can be achieved when the electric device is being charged by using the preset charging parameter. The charging method is applied to the electric device. The electric device is used for connecting to a power supply device via a cable, the power supply device being controlled to supply power to the electric device. Both the electric device and the power supply device support a first protocol and a second protocol. The charging method comprises: controlling the power supply device to charge the electric device according to the first protocol; when determining that the power supply device supports the second protocol, controlling the power supply device to charge the electric device by using a preset charging parameter; and, after controlling the power supply device to charge the electric device by using the preset charging parameter, controlling, according to acquired current carrying capacity information of the cable, the power supply device to charge the electric device according to the second protocol.
