基于台架模拟的纯电动汽车能耗经济性研究

Study on the Energy Consumption Economy of Electric Vehicle Based on Test Bench Simulation

能源和环保问题使纯电动汽车能耗经济性问题被日趋重视,采用台架模拟的方法研究能耗经济性,建立了纯电动汽车能耗试验台架系统,开发了测试系统软件。以实验室研发的ECUV纯电动汽车为对象,在台架上测试不同车速下匀速行驶的百公里能耗作出能耗经济特性曲线,模拟道路循环行驶工况实现续驶里程及能耗仿真计算。通过测试纯电动汽车在不同整车质量下的百公里能耗,分析整车质量对能耗经济性的影响。研究结果用于指导ECUV纯电动汽车能耗性能的改善及续驶里程的提高,对开发其它电动汽车具有参考作用。

The evaluation of EV energy consumption economy is emphasized because of energy and environmental issues.The work studies the energy consumption economy based on the method of test bench simulation,which included a dynamometer and related software.Taking the ECUV vehicle as an object,hundred kilometer energy consumption is tested in different vehicle speeds and driving cycles.Energy consumption economic characteristic curve is depicted in figure and drving range is calculated.Vehicle mass influence on the energy consumption economy is analyzed through testing the EV＇s hundred kilometer energy consumption.The result is used to improve the ECUV vehicle energy consumption performance and increase the driving range,and also provides the references for the development of other EVs.
