电动汽车用动力电池综合性能评价方法的研究

Study on the general performance evaluation of the traction battery for EVs

用层次分析法对电动汽车用动力电池的综合性能进行评价研究,提出了一种科学的动力电池综合评价体系,解决了长期以来动力电池综合评价和方案选择时的盲目性.以纯电动客车为例,通过各影响因素重要性的两两比较,计算出各因素的权重.最后通过北京市电动汽车实际示范运行的数据,验证了该评价方法的科学性.

An estimating system for general performanace evaluation of electric vehicles＇ traction batteries was established by using the analytic hierarchy process （AHP） methed, and the problem of the blindness when choosing and evaluating traction batteries was resolved. Taking EV bus for example, the proportionment of every factors was figured out after comparing one to another. And the estimating system was proved right and practical by the results of the demonstrating running of EV bus in Beijing.
