Abstract：Wireless charging technology for electric vehicles effectively improves the convenience and safety of charging. Dynamic wireless charging technology realizes the “charging while driving” of electric vehicles. The range anxiety can be solved through real-time power supply, and then the vehicle battery capacity can also be reduced. Magnetic coupler is the key component of wireless power transfer in dynamic wireless charging system, which directly determines the transmission characteristics of the system. Therefore, it has become the focus of researchers. Firstly, this paper introduces the development of dynamic wireless charging system for electric vehicles. Then, combined with the classification of magnetic couplers, the main structure types and characteristics of the current research are analyzed. And the key issues and research status of magnetic coupler are introduced in detail. Finally, the issues of magnetic coupler which need to be studied in the future are discussed.
