Claim 15:
16. A wireless charging method, applied to a wireless charging apparatus, wherein the wireless charging apparatus comprises a voltage conversion circuit, an excitation coil, n resonance coils, and a controller, the voltage conversion circuit is connected to the excitation coil, the n resonance coils are arranged in different directions, n is an integer greater than or equal to 3, and the method comprises:
converting, by the voltage conversion circuit, a power grid voltage into a high-frequency alternating current voltage;
generating, by the excitation coil, a magnetic field based on the high-frequency alternating current voltage;
conducting, by the resonance coils, the magnetic field; and
monitoring, by the controller, power statuses of the resonance coils, and enabling or disabling the resonance coils based on the power statuses.
