摘要
分析了纯电动汽车供能策略的5大决策要素:城市电网运行特征,电池与充电技术,纯电动汽车交通功能定位,纯电动汽车节能减排效益以及土地资源约束等.综合各决策要素,提出纯电动汽车供能应有别于传统燃油车自由式加油模式,而须实施夜间低谷充电为主、白天快速补电与更换电池组为辅,结合各类型交通方式出行特征,提供组合型供能模式的能源供给策略.进一步界定了常规充电站、快速充电站与电池更换站的服务定位及布局要求.研究成果对于完善纯电动汽车能源供给体系,指导供能设施建设具有重要意义.
This paper presents an analysis of five decisive elements of the energy supply strategy for battery electric vehicles（BEVs）,which include the characteristics of urban electric network,the technique of battery and charging,the usage pattern of BEVs,the effect of energy saving and emission reduction,and the constraint of urban land resources.With a consideration of these five decisive elements,this paper argues that the energy supply mode for BEVs should be different from that for traditional petrol vehicles.Energy supply of BEVs is proposed to be mainly dependent on charging at night during the low electric demand period.The modes of quick-charging in the daytime and battery-replacing should act as supplementary methods.Then the service function and layout requirements of the slow-charging piles,fast-charging stations and battery swap stations are proposed based on the energy supply strategy.The study results are of great importance to the energy supply system and the upcoming rigorous construction of energy supply facilities.
