Description

technical field [0001] The present invention relates to the technical field of wireless charging, and more specifically, to a wireless charging system and device for intelligently adjusting charging power. Background technique [0002] Wireless charging technology (Wireless charging technology), derived from wireless power transmission technology, can be divided into electromagnetic induction type, magnetic field resonance type and radio wave type according to its charging principle. Low-power wireless charging often uses electromagnetic induction type, such as charging mobile phones. The principle of wireless charging and electromagnetic induction wireless charging is as follows. The alternating current of a certain frequency in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmitting end to the receiving end. At present, the most common charging solution uses electromagnetic indu...
