Analysis of Architecture and Propulsion System for Electric Vehicle

在电动汽车技术领域,每种类型的电动汽车都在能量密度、功率密度、燃料经济性、尺寸、重量、成本和安全性等各方面有其自身的优势和局限所在。所有的这些因素都严重受汽车自身的结构和动力系统的影响。列举了纯电动汽车、混合动力电动汽车及燃料电池电动汽车的动力系统结构,分析其各自的性能特点、最优工况及制约其大规模发展的主要因素。

In Electric vehicle technology each kinds of vehicles have their own capability and limitation in terms of energy density, power density, fuel economy, size, weight, cost, safety,and so on. All these factors are heavily governed by the particular vehicle architecture and propulsion system configuration. This article lists the architecture and propulsion system of the pure electric vehicles, hybrid electric vehicles and fuel cell electric vehicle. And analysis of their own performance characteristics, the best working conditions, and the major factors that restrict their comprehensive development.
