新能源汽车电磁感应无线充电技术的研究

Research on Electromagnetic Induction Wireless Charging Technology for New Energy Vehicles

摘要: 由于我国新能源汽车信息技术在不停的翻新发展，导致传统的有线充电方式已不能完全满足其充电方式的需求。本文首先通过磁场共振式，磁耦合谐振式，电磁感应三种无线充电技术的比较，然后介绍电磁感应的无线传输技术；对其电能传输原理进行分析与比较，最后得出电磁感应式具有可小型化，造价较便宜，电能传输效率较高，无较大辐射等优点，此技术国内外已开始在社会应用，可知有良好的发展前景。

Abstract: Due to the continuous renovation and development of new energy vehicle information technology in China, the traditional wired charging mode cannot fully meet its charging mode. This paper first compares three kinds of wireless charging technology, magnetic resonance, magnetic coupling res-onance and electromagnetic induction, and then introduces the wireless transmission technology of electromagnetic induction. The principle of power transmission is analyzed and compared, and the conclusion is that the electromagnetic induction has the advantages of miniaturization and low cost, high power transmission efficiency, no large radiation and other advantages, this technology has begun to be applied in society at home and abroad, it has a good development prospect.
