Wireless charging technology allows devices (e.g., electric cars) in the case of without the use of wire or cable to charge and discharge automatically connected to the grid,According to the principle of charging, wireless charging technology (WPT, wireless power transmission) can be divided into three types: radio waves, electromagnetic induction, magnetic resonance,
Among them, the electromagnetic induction and electromagnetic resonance in medium and small distance of energy transfer efficiency is higher, more suitable for electric vehicle charging,
Divided according to the charging mode, charging wireless charging technology can be divided into dynamic and static charge,
Dynamic charging system is easy to use, and can recharge of vehicle driving conditions, on the market at present the main technology development company focused on more dynamic wireless charging system, in order to satisfy the demands of growing commercial electric vehicles,
