The present disclosure provides a charging method, device, and system. The charging device includes a voltage regulation circuit, and can charge a charged device through voltage step-down or voltage step-up. In addition, the charging device and a charged device can transfer statuses of a circuit and a battery through a change of a switch status, so that the charging device can regulate a charging voltage and/or a charging current based on the statuses of the circuit and the battery.

Charging method, device, and system

In the wireless charging receive apparatus of the electronic device, a first communication circuit receives charging data, where the charging data is used to indicate a charging type. A first controller identifies, based on the charging data, that the charging type is a first charging type, and outputs a first rectifier control signal to control a first rectifier circuit to operate in a half-bridge mode. Alternatively, a first controller identifies, based on the charging data, that the charging type is a second charging type, and outputs a second rectifier control signal to control a first rectifier circuit to operate in a full-bridge mode. A first receive coil receives an alternating magnetic field and outputs a first induced voltage.
