The power receiving side resonant capacitor forms a power receiving side LC resonant circuit; and the power transmitting side LC resonant circuit and the power receiving side LC resonant circuit have the same resonant frequency. When the wireless charging coil 102 is energized, the power-transmitting side LC resonant circuit will generate a high-frequency oscillating magnetic field; the magnetic field and the electric field at any position at any time in this high-frequency oscillating magnetic field are orthogonal to each other, and are different in phase. 1/2π, and the magnetic field intensity is much higher than the electric field intensity. This space electromagnetic field can store energy, but the synthesized electromagnetic wave power flow density is zero and will not transmit any energy. That is to say, this field will not radiate outwards or Will be lost inwards. When the wireless charging coil 102 is close to the wireless power receiving coil 101, the wireless power receiving coil 101 will fall into the range of the high-frequency vibration magnetic field. Since the power receiving side LC resonant circuit has the same resonant frequency as the power transmitting side LC resonant circuit, the power receiving coil 101 will fall into the range of the high-frequency vibration magnetic field. The side LC resonant circuit will generate resonance of the same frequency magnetic field, so that energy is coupled from the wireless charging coil 102 to the wireless power receiving coil 101 in the form of magnetic resonance, and is provided to the battery 10 .
