Abstract
A wireless charging receiver, transmitter, system, and control method, and an electric vehicle are provided, which relate to the field of wireless charging technologies. A low-frequency magnetic field receive coil of the receiver converts a low-frequency magnetic field into an induced signal. A receiver controller is configured to: when all low-frequency magnetic field transmit coils stop working, allocate a signal feature different from that of a current induced signal to each low-frequency magnetic field transmit coil, and send a correspondence between each low-frequency magnetic field transmit coil and the allocated signal feature to the wireless charging transmitter; and is further configured to determine, when the low-frequency magnetic field transmit coil works, relative positions of the power transmit coil and the power receive coil by using an induced signal having the allocated signal feature.
