ELECTRONIC DEVICE

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. When determining that the electronic device is not in the forward charging state based on the connection information of the at least one charging interface, and any one or more charging interfaces are connected to the receiving device, the controller is configured to control the battery charging controller to switch to the reverse charging state and control a second reverse charging link corresponding to the charging interface connected to the receiving device to be turned off
