电动汽车无线充电系统发展现状与应用

Development Status and Application of Wireless Electric Vehicle Charging System

随着国家对新能源汽车发展的大力支持,纯电动汽车已经逐渐普及开来。为了有效解决里程焦虑影响,与纯电动汽车相配套的充电设施也正在大规模投入建设中。但现有的插入式充电模式在充电效率上仍然无法替代传统燃油汽车的便捷性。因此,无线电动汽车充电系统在汽车上的应用研究被提上日程。无线电动汽车充电系统可以为电动汽车充电,且摒弃了插入式充电系统的弊端。论文针对目前电动汽车的静态和动态的不同类型无线充电系统的工作原理、结构、电磁兼容性、气隙敏感度、位置敏感度、补偿网络等进行对比分析研究,分析了用于电动汽车无线充电系统的基本工作过程,基于现有系统提出无线电动汽车充电系统的未来应用场景,对大功率电动汽车无线充电技术的应用具有良好的参考意义。

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 wirelesscharging systems of electric vehicles, describes the basic structure and working principle of thewireless charging system for electric vehicles. Based on the existing system, the future applicationscenario of the wireless electric vehicle charging system is proposed, which has a good referencesignificance for the application of the wireless charging technology for high-power electric vehicles.
