Description

technical field [0001] The invention belongs to the field of wireless charging, and in particular relates to a foreign matter removal system and a control method thereof. Background technique [0002] Electric vehicle (EV) is a representative of new energy vehicles emerging in recent years, which has the advantages of environmental protection, no pollution, convenient use and zero emission. Electric vehicles rely on the on-board battery pack to provide power, and the on-board battery pack needs to be recharged frequently to ensure sufficient power. At present, the main charging method is wired charging such as charging piles. This charging method has the disadvantages of easily generating sparks and wear when plugged in, not safe enough, and difficult to maintain. The emergence of wireless power transmission technology gets rid of the dependence of electric vehicles on wires, can effectively overcome the above shortcomings, and has the advantages of convenient operation an...
