Wireless charging method, receiver, terminal device, and charger

Abstract

A wireless charging method, a receiver, a terminal device, and a charger are provided. A receiver () includes an oscillation circuit (), a power processor (), a sampling control module (), and an auxiliary power supply module (). In a ping phase, the oscillation circuit receives first energy sent by a transmitter (), and the sampling control module collects a first voltage value output by the oscillation circuit based on the first energy, and when the first voltage value is less than a startup voltage value of the power processor, controls the auxiliary power supply module to supply power to the power processor, so that the power processor is started. In a power transfer phase, the power processor sends a power transfer instruction to the transmitter, so that the transmitter sends second energy based on the power transfer instruction, to provide electric energy for a load in the receiver.
