Abstract: With the strong support of the government for the development of new energy vehicles, pure electric vehicles have gradually become popular. In order to effectively address the impact of mileage anxiety, the charging facilities matched with pure electric vehicles are also being put into construction on a large scale. However, the existing plug-in charging mode can not replace the convenience of traditional fuel vehicles in terms of charging efficiency. Therefore, the application research of the wireless electric vehicle charging system in the automobile is put on the agenda. The wireless electric vehicle charging system can charge the electric vehicle and discard the disadvantages of the plug-in charging system. This paper compares and analyzes the following contents, such as the working principle, structure, electromagnetic compatibility, air gap sensitivity,position sensitivity and compensation network of different types of static and dynamic wireless charging systems of electric vehicles, describes the basic structure and working principle of the wireless charging system for electric vehicles. Based on the existing system, the future application scenario of the wireless electric vehicle charging system is proposed, which has a good reference significance for the application of the wireless charging technology for high-power electric vehicles.
