摘　　要：动力性指标与经济性指标在纯电动汽车的设计和使用过程中既相互联系,又相互对立,因此应对其进行综合评价。通过文献统计,选择最高车速、加速能力、爬坡能力、续驶里程、百公里耗电量作为纯电动汽车动力性与经济性的综合评价指标,构建了应用于纯电动汽车动力性经济性综合评价的指标体系,采用层次分析法和熵值法综合确定各指标权重,以理想解法进行排序,建立了基于AHP-熵权-TOPSIS的纯电动汽车动力性与经济性的综合评价模型,并以实例说明了模型的应用。The power performance index and economic index in the design and application process of battery electric vehicle （BEV） are mutually related as well as opposite. So they should be evaluated synthetically. From the analysis of literatures, the maxi- mum speed, acceleration performance, gradeability, driving range and energy consumption per 100 km are chosen as the synthetic e- valuation indices. And the evaluation index system for the synthetic evaluation of the power performances and economic performances of BEV is established. The Analytic Hierarchy Process （AHP） and entropy method are adopted to define the weight of each index. By TOPSIS （Technique for Order Preference by Similarity to Ideal So- lution） method, the synthetic evaluation model of the power per- formance and economic performance of BEV is established basing on the AHP-Entropy method-TOPSIS. And example is used to ex- plain the application of the model.
