摘要： 虽然电动汽车市场占有率逐步提高，但由于电动汽车充电时间远大于传统燃油车加油时间，因此，现阶段电动汽车续航里程仍然是消费者及车企重点关注的焦点问题。论文根据电动汽车能量转化原理及仿真分析流程，运用 Matlab 搭建电动汽车中国轻型乘用车行驶工况（CLTC-P）续航仿真分析模型，并对比实车测试与仿真分析结果验证仿真分析精度，最后分别改变仿真模型中车重、滚动阻力、空气阻力、电驱效率、电池放电量等变量，通过仿真分析，得出各因素对续航里程的影响，为车企提升电动汽车续航里程提供理论依据。

Abstract: Although the market share of electric vehicle has gradually increased, however, the charging time of electric vehicle is much longer than that of traditional fuel vehicles, therefore, at this stage, the range of electric vehicle still is the focus of consumers and car enterprises. According to the energy conversion principle and simulation analysis process of electric vehicle, the paper uses Matlab to build the simulation analysis model of electric vehicle under China light-duty vehicle test cycle passenger car (CLTC-P) working condition, and compares the results of real vehicle test and simulation analysis to verify the accuracy of simulation analysis, finally, changing the vehicle weight, rolling resistance, air resistance, electric drive efficiency and battery discharge in the simulation model, the influence of various factors on the range is obtained by the simulation analysis, which can provide a theoretical basis for vehicle enterprises to improve the range of electric vehicles.
