WIRELESS CHARGING RECEIVER AND WIRELESS CHARGING METHOD

Embodiments of this application disclose a wireless charging receiver and a wireless charging method. The method includes: receiving, by a receiver by using a first oscillation circuit, pulse energy emitted by a transmitter, where the first oscillation circuit includes a first receiving coil configured to convert the pulse energy and output power; when a voltage value output by the first oscillation circuit reaches a first reference voltage value, sending, by the receiver, a power transfer instruction to the transmitter by using a communications module, so that the transmitter emits energy according to the power transfer instruction, where the first reference voltage value is a working voltage threshold of a processor; and receiving, by the receiver by using a second oscillation circuit, the energy emitted by the transmitter according to the power transfer instruction. Because a new coil is disposed in the receiver, a coupling factor between the receiver and the transmitter in a ping phase is higher, and a degree of freedom is improved. After a preset voltage value is reached, the receiver receives, by using the receiving coil, the energy transferred by the transmitter. This ensures transfer efficiency while improving the degree of freedom.
