新能源汽车动力传动系统优化研究

Research of Power Transmission System of the New Energy Automobile

为促进新能源汽车发展,实现汽车行业节能减排目标,介绍了新能源汽车的分类,按照动力来源,分为混合动力电动汽车(HEV)和纯电动汽车(BEV)。分析了传动系统的主要类型,即单电机传动系统、主电机+轮毂电机传动、双电机双轴驱动纯电汽车驱动系统,提出了串联式混合动力系统、并联式混合动力系统、混联式混合动力系统的优化方法。

In order to promote the development of the new energy automobile,and achieve the aim of energy conservation and emission reduction of auto industry,the research introduces the classification of the new energy automobile.According to the power source,they are divided into HEV and BEV.The research analyzes the main types of drive system,i.e.single motor drive system,main motor+hub motor drive,dual-motor and dual-shaft drive pure electric vehicle drive system.The optimization methods are proposed,including hybrid power system of tandem,parallel and series-parallel type.
