增程式电动汽车

Extended Range Electric Vehicle

为了解决目前汽车行业存在的废气排放以及能源短缺问题,各国均积极开发电动汽车,增程式电动汽车是电动汽车中的一种。文章从增程式电动汽车的定义出发,介绍了其结构、工作原理特点等以及其与串联式混合动力的区别,阐述了目前国内外增程式电动汽车的发展概况并重点介绍了Volt增程式电动汽车。分析结果表明:增程式电动汽车兼具纯电动汽车和混合动力汽车的优点,具备很强的市场推广价值。

In order to solve the current existing problems of exhaust emission and energy shortage in automobile industry, many countries are vigorously developing electric vehicles, including the extended range electric vehicle （EREV）. The paper firstly introduces the definition of EREV, and then explains its structure, working principles and the differences between EREV and series hybrid electric vehicle. Subsequently the current overview of the development of EREV both at home and abroad has been presented. The famous EREV-Volt is mainly demonstrated as a good example. The results show that, it co,nes to the conclusion that EREV possesses advantages of both pure EV and HEV,and having a strong marketing value.
