摘要电动汽车是国家着力推动的新能源计划的重要组成部分,其车载电池的研究制造及管理系统的开发占据着重要的位置。目前动力电池的充电以有线整充为主。磁谐振式无线电能传输技术是基于谐振耦合现象,利用近场磁场进行非辐射性、中距离输电的新技术,据此一些高校和研究院所也针对电动车提出无线整充的方案。整充方式没有把电池能量管理和电能传输结合起来考虑,而是两个分离的系统单独运行,电池均衡过程造成充电效率不高。文章结合动力电池的电池能量管理特点,充分利用无线电能传输的特有传输方式,提出动力电池组的分组式无线充电及具体实施方案,探讨了技术实现的关键点,为电池管理设计提供新思路,开拓了无线电能传输技术的新应用。

Abstract：Electric vehicles are an important part of the new energy project that our country is promoting. The research and manufacture of their batteries and the development of management systems play an important role. At present, the existing solutions to power batteries charging are mainly wired whole vehicle charging. Magnetic resonant wireless power transmission technology is a new technology which carries out non-radiative, mid-range power transmission using the near magnetic fields based on coupled resonance phenomena. Many universities and research institutes have put forward some applicable solutions using wireless whole vehicle charging. Wireless whole vehicle charging doesn’t combine the battery energy management with power transmission. Two separate systems run separately on this occasion, and the charging efficiency is low due to the battery balancing process. Combining the features of battery power management and using fully the special ways of wireless power transmission, we proposes the integration of battery energy management and wireless charging systems, put forward some specific implementing plans, and discuss the key points of the application of the technology. This study provides new solutions to battery management design and develops new applications for wireless energy transmission technology.

Key words： Electric buses battery packs wireless power transmission coupled resonance
