本文对在瑞典哥德堡运营的一辆串联插电式混合动力公共汽车进行了油箱-车轮（TTW）分析。描述了总线和动力系统模型。阐述了评价TTW能量转换的回热效率和燃料-牵引效率的定义和计算方法。针对两种基于优化的能源管理策略，对这两种效率进行了量化和比较，其中使用了凸建模和优化。减小电池尺寸对这两个效率的影响也进行了研究。
This paper is concerned with the tank-to-wheel (TTW) analysis of a series plug-in hybrid electric bus operated in Gothenburg, Sweden. The bus line and the powertrain model are described. The definition and the calculation method of the recuperation and fuel-to-traction efficiencies are delineated for evaluating the TTW energy conversion. The two efficiencies are quantified and compared for two optimization-based energy management strategies, in which convex modeling and optimization are used. The impact of downsizing the battery on the two efficiencies is also investigated.
