Wireless charging wireless charging mainly through the following three ways: electromagnetic induction, radio waves, electromagnetic resonance
At present, the most common wireless charging solution is: electromagnetic induction, which generates current through the primary and secondary coils to transfer energy from the transmission segment to the receiving end. The solution providers include companies such as Splashpower, WildCharge and Fulton Innovation in the United Kingdom. . The industrialization of wireless charging technology based on the principle of electromagnetic induction is the most mature. There are three core technologies in the electromagnetic induction wireless charging system: resonance control, high-efficiency power transmission, and data transmission. Several key technical issues have not been resolved until recently, and the solution is constantly evolving.
