Abstract

See full text

A wireless charging apparatus for a wireless power transmission system and a method are provided. The apparatus includes a voltage conversion circuit, an excitation coil, n first resonance coils, and a controller, where n is greater than or equal to 3. The voltage conversion circuit is connected to the excitation coil and converts a power grid voltage into a high-frequency alternating current voltage. The excitation coil generates a magnetic field based on the high-frequency alternating current voltage. The n first resonance coils are arranged in different directions and conducts the magnetic field, and the controller monitors power statuses of the first resonance coils, and enable or disable the first resonance coils based on the power statuses.
