Plug-in混合动力汽车动力系统参数设计成本效益分析

基于成本效益分析,以年均使用成本和初始成本作为评价指标,建立插电式混合动力汽车(PHEV)动力系统设计分析模型,对PHEV动力系统纯电动续驶里程和能量储存装置参数的进行设计分析。以Prius为分析对象,结果显示当PHEV纯电动续驶里程等于汽车的日行驶里程时,节油量最大且年均成本最小,同时也得到了国内个人交通出行数据统计对PHEV设计的重要性。能量储存装置的容量、放电深度和功率对PHEV质量和初始成本均有较大影响,基于功率/能量比(RP/E)分析了能量储存装置参数对PHEV动力系统成本的影响。

Cost-benefit Analysis of Parameter Design of Powertrain for Plug-in Hybrid Electric Vehicle

Based on the cost-benefit analysis,with the evaluation index of annual cost and initial cost,the design and analysis model for powertrain for plug-in hybrid electric vehicle(PHEV) had been established and the parameter of PHEV′s powertrain had been studied.When the PHEV′s all-electric range(AER) is equal to the daily distance,the best average annual cost and the largest reduction in petroleum consumption are achieved.And obtain the importance of the personal transportation survey for PHEV.Energy storage system(ESS) capacity,the depth of discharge and power of ESS can designed based on PHEV′s service life,cost,mass and size,and obtain the PHEV′s powertrain cost based on power/energy ratio(RP/E) analysis.
