面向城郊公交纯电动小巴动力系统匹配及经济性研究

Research on power system matching and economy of pure electric minibus for suburban public transportation

在目前原材料价格上涨和实现碳达峰碳中和战略目标的背景下,开发节能减排、低碳环保的城郊公交纯电动小巴替代燃油版小巴很有必要。本文简述了新能源汽车相关政策,以海口城郊公交小巴为研究对象,调研实际需求,设计出具有太阳能辅助充电的城郊公交纯电动小巴,并进行了动力系统匹配,通过使用仿真软件实验,优化改进了相关参数,同时进行了经济性对比分析。结果表明:太阳能辅助充电的城郊公交纯电动小巴参数合理,较好地满足需求,增加了续航里程,节约了电能及动力电池容量,具有较高的经济性。

With the current rise in raw material prices and the realization of the strategic goal of carbon peak and carbon neutrality,it is very necessary to develop energy-saving,low-carbon and environmental friendly suburban bus pure electric minibuses to replace fuel version minibuses.This paper briefly describes the relevant policies of new energy vehicles.Taking Haikou suburban bus as the research object,investigating the actual needs,designing a suburban bus pure electric minibus with solar assisted charging,and carrying out the power system matching.Through the use of simulation software experiments,the relevant parameters are optimized and improved,and the economic comparative analysis is carried out at the same time.The results show that the solar assisted charging suburban bus pure electric minibus has reasonable parameters,better meets the demand,increases the mileage,saves electric energy and power battery capacity,and has high economy.
