摘要
针对电动汽车动力电池包中单体电池性能差异造成的不良影响 ,探讨了几种均衡技术。研究了集中均衡 ,以及分散均衡中的隔离式均衡和非隔离式均衡方法。分析了集中均衡系统和分散均衡系统的适用场合。通过集中均衡器对NiMH电池包的均衡实验 ,表明均衡不但能缩小电池电压的差异 。
In view of the differences of individual cell performance in traction battery pack of electric vehicle(EV),several equalization technologies and their applicable cases are investigated.The results of equalization experiment on NiMH battery pack with centralized equalizer show that equalization can reduce the difference of cell voltages and increase the discharge capacity of the battery pack.
