This application provides a wireless charging alignment method and apparatus, a wireless charging system, and an electric vehicle, and belongs to the field of wireless charging. In the wireless charging alignment apparatus, a first detection circuit may detect a first induction signal of a power receive coil in a positioning magnetic field generated by a power transmit coil; a second detection circuit may detect a second induction signal of a location detection coil in the positioning magnetic field; and a location determining circuit may determine a location of the power receive coil relative to the power transmit coil based on the first induction signal and the second induction signal. Compared with a related art in which a driver visually detects relative locations of two coils, in this embodiment of this application, precision of the relative locations determined based on the two types of induction signals is higher. Therefore, precision of alignment between the power receive coil and the power transmit coil can be effectively improved.
