纯电动汽车能耗经济性评价体系初步探讨

Preliminary Study on Evaluation System of EV Energy Consumption Economy

以纯电动汽车长期运行试验为基础,对电动汽车能耗经济性的合理评价方法进行了研究,总结了续驶里程、单位里程容耗、单位里程能耗等纯电动汽车常用的能耗经济性评价参数,比较了不同参数评价的优劣,提出了能量利用率作为纯电动汽车能耗经济性和动力性综合评价参数,并对不同车型进行了能量利用率计算与分析.对纯电动汽车能耗经济性评价的参数体系及不同车型间能耗经济性比较的参数标准进行了初步探讨.

<Abstrcat> To define the evaluation standard of EV energy consumption economy and establish the evaluation system, the reasonable evaluation method of EV energy consumption is studied on the basis of long-term running test of EV. The parameters of energy consumption economy such as driving range, capacity consumption per kilometer and energy consumption per kilometer are summarized. The merits and faults of these parameters are mentioned. As the overall merit of dynamic performance and energy consumption economy the energy utilization ratio is put forward. The function of this parameter is shown through calculation and analysis for different EVs. This is helpful to the study of the EV energy consumption economy and the comparison of energy consumption economies for different electric vehicles.
