Abstract

This application discloses a wireless charging receiver and a wireless charging method. The method includes: receiving, 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 a power transfer instruction to the transmitter, 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 using a second oscillation circuit, the energy emitted by the transmitter according to the power transfer instruction.
