- May 21, 2018 -

IHS Markit research director David Green (David Green) explains that in general, there are three kinds of wireless charging technologies. One is the charging pad, which uses tightly coupled electromagnetic induction technology or short range charging technology. One is a charging bowl or a charger that penetrates the surface. It uses a loosely coupled electromagnetic resonance charging technology, which can transmit electricity several centimeters apart. Another is decoupling RF wireless charging technology, charging distance is far away.
