Abstract: This application provides an electronic device, including a battery, at least one charging interface, a PD controller, a battery charging controller, a first reverse charging link, at least one second reverse charging link, and a controller. The first reverse charging link is coupled to the battery charging controller. The battery charging controller includes a forward charging state and a reverse charging state. The charging interface is coupled to the battery through the first reverse charging link, and is further coupled to a power output end of the PD controller through the second reverse charging link. The PD controller is configured to obtain connection information of the charging interface. The connection information indicates a connection status of the charging interface and indicates a device type of an external device and/or the electronic device.
