Wireless charging is a kind of technology that uses non physical contact to realize power transmission. At present, there are three common wireless power transmission technologies, which are electromagnetic induction, electromagnetic resonance and radio wave. Among them, electromagnetic induction is a widely used way, which not only has high charging efficiency, but also has low cost.

The working principle of electromagnetic induction wireless charging technology is: the transmitting coil is installed on the wireless charging base, and the receiving coil is installed on the back of the mobile phone. When the mobile phone is close to the charging base for charging, the transmitting coil will generate alternating magnetic field due to the AC connection. The change of magnetic field will make the receiving coil generate induced current, which will transfer the energy from the transmitting end to the receiving end, and finally complete the charging process.
