基于济南市城市道路运行工况，对比分析了纯电动汽车和传统燃油汽车的能耗及排？放。根据纯电动汽车及传统燃油汽车的实车道路~,riL数据，利用主成分分析、聚类分析等方法构建了济南市城市道路工况。基于该工况，对比分析了上述两种车辆的能耗和排放，分析得出在该道路工况下纯电动汽车的能耗约为传统燃油汽车的1／2，排放方面也明显低于后者。“,”The energy consumption and the emission of an EV and a gasoline vehicle were com- pared based on road conditions in Jinan city. The road conditions in Jinan were developed according to the practical road testing data from the EV and the gasoline vehicle by principal component analy- sis and cluster analysis. The comparison results show that the EV energy consumption is 50% lower than that of the gasoline vehicle beside that its emission is much lower.
