摘要
随着能源及环保问题的日益加剧,各国都在大力发展电动汽车。然而电池技术的不成熟,特别是电池成组使用时的不一致性成为制约电动汽车发展的最大瓶颈。为了均衡电池组单体存在的差异性,提高电池组的整体性能,分析了几种常见的电池组均衡电路的优缺点,从中选出一种均衡方案,对电池组进行均衡管理和控制,以达到良好的均衡效果,提高串联电池组的整体性能。
Since the growth of energy and environmental problems, the development of electric vehicles is improving. While, because of the lack of battery technology that specially reflects in inconsistency of battery pack, the development has met the bottleneck. In order to balance the difference between battery cells and to improve the performance of battery pack, advantages and drawbacks of several common balancing circuits are analyzed in this paper. Based on the analysis, one scheme is chosen, which can control balancing circuit and improve the overall performance, to achieve a good balancing effect.
