Abstract: The energy consumption of pure electric vehicles is one of the research hotspots of new energy vehicles. The establishment of the energy consumption model of pure electric vehicles is of great significance for planning the economic speed, estimating the driving range, and evaluating the energy saving effect of pure electric vehicles. According to the vehicle dynamics, the relevant calculation formulas of pure electric vehicles are obtained by analogy with the driving force calculation formula and fuel consumption formula of traditional fuel vehicles, and the energy consumption model is corrected by CRUISE simulation software. The results show that the accuracy of the model after correction is 94.48%, and the model has good robustness.

Key words: Pure electric vehicles; Vehicle dynamics; Energy consumption model; CRUISE simulation software

摘要: 纯电动汽车能耗是新能源汽车的研究热点之一。纯电动汽车能耗模型的建立,对于规 划经济速度,估算续驶里程的基础,评估纯电动汽车的节能效果有重要的意义。文章根据汽 车动力学从传统燃油车的驱动力计算公式和燃油消耗公式类比得出纯电动汽车的相关计算公 式,利用 CRUISE 仿真软件仿真,校正能耗模型。结果表明,经过校正后的模型精度为 94.48%, 该模型具有良好的鲁棒性。
