电动汽车无线充电用磁耦合机构研究进展

摘要

On demand of a sustainable, green, and low-carbon economy development, there is a worldwide stimulation on the progress of Electric Vehicle (EV) industry. The wireless charging technique, embodying advantages of convenience, safety and low-maintenance, has been gaining interests from both the academia and industrial community. It is promising to be the future trend for the EV charging technology. And the magnetic coupler which enables wireless charging is the most essential part in a wireless charging system. In this paper, the latest research progress in the development of EV oriented wireless charging system, especially the magnetic coupler, which is the most important unit, was reviewed internationally. Besides, the pioneering deployments and commercializing trial of the wireless charging system using EV was highlighted as well. At last, challenges to be addressed and perfections to be made in the near future on the magnetic coupler were summarized.%发展电动汽车是节能、环保和低碳经济的需求，而无线充电技术以其安全、便捷和低维护的优点，越来越受到学术界和工业界关注，是未来电动汽车供电技术的发展趋势。磁耦合机构是无线充电系统中实现电能无线传输最为关键的部件。文章介绍了近几年来国际上电动汽车无线充电系统开发及其磁耦合机构研发的最新研究进展，包括电动汽车无线充电实用化和产业化的最新进展，最后讨论和总结了磁耦合机构研究的难点和发展趋势。
