摘　　要：讨论了电动汽车动力传动系统传统的评价指标,指出动力性评价指标仅仅反映电动汽车的一种极限能力,与实际使用工况无关。基于各主要部件在不同工况下效率不同这一事实,提出了"能量效率区间利用率"和"能量效率发挥程度"的概念,给出了计算区间加权效率的准加权法。然后,从能量利用的角度出发,提出"驱动能量效率"和动力传动系统"综合评价指标",建立了电动汽车动力传动系统合理匹配评价体系。最后,对某型号电动汽车的评价参数进行了分析和计算。The evaluation index for dynamic power-train of electric vehicles （EVS） is discussed. It is indicated that evaluation index of dynamic performance only reflects the utmost ability of EVS and has no relation to usage condition in fact. Based on the fact that efficiency of the main parts is different in different working conditions, the idea of ＂interval usage percentage of energy efficiency＂ and ＂exertion degree of energy efficiency＂ is put forward. The quasi weighted method of calculating interval weighted efficiency is pointed out. The ＂driving energy efficiency＂ and ＂synthetic evaluation index＂ of power-train is put forward from the point of energy usage. The evaluation system of EVS dynamic power-train for reasonable matching is established. Lastly, the analysis and calculation of evaluation parameters of some type of EVS are carried out.
