       The principle of wireless charging is that through near-field induction, the wireless charging device transmits the energy to the terminal device, and the terminal device converts the received energy into the battery of the electric energy storage device.

     At present, there are three ways of wireless charging: Battery induction, nuclear magnetic resonance and radio wave. Electromagnetic induction generates a certain current in the secondary coil through electromagnetic induction, so as to transfer the energy from the transmission circuit to the receiving terminal. Nuclear magnetic resonance is composed of energy transmitting and energy receiving devices. The two devices exchange each other's energy at the resonance frequency, Radio wave type is power supply configuration, radio wave transmitting device, receiving configuration, receiving configuration, and DC voltage output input for transmission
