摘要/Abstract

摘要： 从整车能量消耗入手,分析纯电动轿车能量流机理,建立整车耗电量与工况、整车参数、部件效率以及制动能量回收比例之间的函数关系,通过求解基于工况的特征权值,研究不同车型在各工况中的节能潜力,为纯电动轿车整车参数匹配提供理论依据。通过分析制动力分配策略,量化制动能量回收比例,进一步计算整车节能度,研究制动能量回收效果。通过在Matlab/Simulink中构建仿真模型,完成整车节能度的计算,并与AVL/Cruise仿真结果进行对比分析,结果表明本文方法能够很好地反映整车节能效果,完全满足整车节能潜力分析的要求。

Abstract: Starting with the whole vehicle energy consumption, the principle of energy flow of electric vehicle was analyzed. The relational functions of electric power consumption to the driving condition, the vehicle parameters, the component efficiency and braking energy recovery ratio are established. By calculating the feature weighting of the driving condition, the potentials of energy-saving of different vehicles under different driving conditions can be analyzed to provide theoretical foundation for matching of parameters of electric vehicle. The function of braking energy recovery ratio was built to calculate the vehicle energy-saving rate based on the braking force allocation algorithm. The simulation model was built on Matlab/Simulink platform to calculate the energy-saving potential and energy recovery efficiency. In comparison with AVL/Cruise simulation, the calculation method of this paper is more effective in analyzing vehicle energy-saving potential.

Key words: vehicle engineering, pure electric vehicle, braking energy recovery, energy-saving rate, simulation analysis
