摘要
国家863计划电动汽车重大专项及北京绿色奥运规划将对电动汽车发展起到重大推动作用。通过电动公交车的运行试验,对电动汽车用动力电池组不一致性表现形式和形成原理进行了研究,重点讨论了电池组的电压不一致性,对不一致性分布规律进行了总结,指出了电压不一致性与使用时间的关系,确定了其理论正态分布的基本参数,并检验了理论与实际分布的接近度。提出了在使用中防止电池组不一致性扩大的措施。
Specialized electric vehicle(EV) project of the national 863 project and Beijing Green Olympic project will improve EV development condition. According to the test of EV bus, the expressive form and generation principle of the battery pack imconsistency were studied; voltage inconsistency was mainly discussed. Regularities of distribution were generalized; commection of voltage inconsistency and service time was showed; theoretical nomal distribution and its basic parameters were determined; and conformity between theory and practice was verified. In the end, the measures were brought forward to prevent from enlarging the battery pack inconsistency.
