The method is advantaged in that real-time communication of the primary side and the secondary side can be achieved, and safe and efficient operation of the wireless charging system is guaranteed.

Description

technical field [0001] The invention relates to the electrical field, in particular to an electromagnetic induction wireless charging system and a control method for integrating charging and communication thereof. Background technique [0002] Wireless charging technology can be divided into two categories according to different energy transmission methods. One is coupled wireless charging technology, which requires a pair of coupled transmitters and receivers for energy transmission. It can also be specifically divided into electromagnetic induction and electromagnetic charging. Resonance type and electric field coupling type; the other type is radiation type, which uses various forms of radiation waves as carriers, and energy can be transmitted freely in space. According to the different forms of energy carriers, it can be divided into ultrasonic type, radio wave type, microwave and laser. Among them, the electromagnetic induction wireless charging technology is the most ...
