摘　　要：对纯电动客车和燃油客车的轻量化效果进行对比分析。结果表明,两者轻量化的节能效果没有明显的差别,但纯电动客车轻量化还有另一收益,即可使续驶里程显著增加,从而减少动力电池的更换次数,降低电池使用成本。因此,在两种客车减少相同质量,为轻量化付出相同成本的条件下,纯电动客车的轻量化收益高于燃油客车。在目前动力电池成本高、关键技术尚未突破的状况下,纯电动汽车比燃油汽车对轻量化的需求更为迫切。The lightweighting effects of electric buses and fuel buses are comparatively analyzed. The re- sults show that the energy saving effects of !ightweighting for two kinds of buses have no obvious difference, but the lightweighting of electric buses has an additional benefit, i.e. the significant increase in driving range, and hence reduction of battery replacement times, leading to lower cost of battery use. Therefore providing two kinds of bu- ses spend the same cost in lightweighting and reduce the same amount of mass, the benefit of lightweighting for elec- tric buses is higher than that for fuel buses. In current situation of high battery cost with key technologies remained to be broken through, the lightweighting demands for electric vehicles are more urgent than fuel vehicles.
