The Technical Principle Of Wireless Charging
- Jun 06, 2018 -




The core principle of wireless charging is based on electromagnetic induction, and the principle is not complicated. At present, there are two main branches of technology in the industry, one is the magnetic field sensing technology represented by the Qi standard, and the other is the magnetic resonance technology represented by the AirFuel standard.

In principle, MRI is a better solution. It supports far more charging distance, and can support multiple devices to charge simultaneously.

However, MRI technology is not mature at present, and through multiple stacking of the coil, the use of Qi standard wireless charger can also achieve multiple devices charging at the same time.
