摘　　要：随着现代电动汽车产业的飞速发展,对电动汽车的电池能源要求越来越高。电动汽车最需要解决的技术瓶颈之一是电池能量的均衡问题,这是因为串联电池组在充放电的过程中,电池内阻等技术参数的微小差异导致电池的电压出现不一致现象。深入研究了适用于电动汽车的锂离子电池能量均衡系统,提出了合理的系统设计方案与实现方法,由此可消除串联电池组在充放电过程中出现的单体电池电压不均衡的现象,节省了电池电能,大幅度提高了电池组的性能,对发展纯电动汽车具有很重要的意义。With the rapid development of the modern electric vehicle industry, the requirement to the battery technology be- comes more and more important. One of the technical bottlenecks to be solved for the electric vehicles is a problem of the battery energy balance, because the battery charging and discharging would cause a phenomenon, such as the unbalanced voltage. A lithi- um-ion battery energy balance system has been developed and realized in this paper, this system can not only save the battery＇s energy, but also improve the battery performances. This study has an important significance to the development of the battery elee- tric vehicles, in the future.
