摘　　要：纯电动汽车的性能主要受动力电池的充放电特性和功率特性的影响,而低温条件下锂离子动力电池的充放电效率下降,功率特性变差制约了纯电动汽车的推广和发展。为了研究低温条件对纯电动汽车性能的影响,本文通过对锂离子动力电池在不同温度下进行的放电实验,研究低温对锂离子动力电池性能的影响,并结合实验数据,基于CRUISE软件选取纯电动汽车车型在低温时对电动汽车性能的影响,进行仿真分析。仿真结果表明,随着温度的降低,纯电动汽车的性能会有明显的下降。The performance of electric vehicles is mainly affected by the charge and discharge characteristics and power characteristics of the power batteries,while the charging and discharging efficiency of lithium-ion power batteries decreases and the power characteristics deteriorate under low temperature conditions,which restricts the promotion and development of electric vehicles.In order to study the impact of low temperature conditions on the performance of electric vehicles,this paper conducts the effect of low temperature on the performance of lithium-ion power battery was studied through discharge experiments at different temperatures,and the influence of low temperature on the performance of electric vehicles was simulated and analyzed based on the experimental data selected by CRUISE software.The simulation results show that as the temperature decreases,the performance of electric vehicles will decrease significantly.
