摘要
常用的电动汽车非接触式充电的工作原理有3种:电磁感应法、微波法和强磁耦合谐振法。回顾了每一种方法的起源,详细介绍了它们在电动汽车非接触式充电领域的研究现状,指出了各种方法在研究过程中暴露出的部分问题。最后,从电能传输功率、传输效率和传输距离3个不同的角度,分析了上述3种方法在电动汽车非接触式充电领域的实用化前景。
Commonly, there are three kinds of contactless charging works in Electric Vehicles （EVs）, which areelectromagnetic induction, microwave, and strongly coupled magnetic resonances methods. In this paper, theorigin of each method is reviewed, the research of them on EVs contactless charging is described in detail,and some problems in the course of the study are exposed. Finally, from three different perspectives of theelectricity transmission power, efficiency and transmission distance, three kinds of contactless chargingmethods in the practical prospects of EVs are analyzed.
