Abstract
Provided are a wireless charging system, device, and method and a device to be charged. The wireless charging system includes the wireless charging device and the device to be charged. The wireless charging device includes a wireless transmitter circuit and a first communication control circuit. The device to be charged includes a battery, a wireless receiver circuit, a first charging channel, a detection circuit and a second communication control circuit. The second communication control circuit is configured to perform wireless communication with the first communication control circuit based on the output voltage and/or the output current of the wireless receiver circuit detected by the detection circuit, such that the first communication control circuit adjusts a transmitting power of the wireless transmitter circuit, to enable the output voltage and/or the output current of the wireless receiver circuit to match a charging stage where the battery presently is.
