In the sending and receiving ends each have a coil, electromagnetic signal transmitting end adjacent coil cable power supply, receiving coil induction sent a real electromagnetic signal, which occurred in the current to charge the battery.
Wireless charging technology to achieve the main via three ways: electromagnetic induction, magnetic resonance type, radio wave type.
