目前全球的现代汽车上仍广泛采用内燃机作为动力源,消耗大量的石油资源,排出大量的废气,以至于全球变暖,空气污染,酸雨,淡水资源危机,资源、能源短缺,噪声污染.电动汽车则是以电力这种可再生资源为能源,既没有有害气体排放也没有温室气体排放,噪音也很小.它是21世纪清洁、高效和可持续的交通工具.
电动汽车的关键部位是动力电源,动力电源系统储存能量的多少是决定电动汽车续驶里程的重要因素.但是目前动力电源技术仍然是发展电动汽车的瓶颈,未能取得突破性进展.电动汽车的续驶里程还不能满足用户的需求,如果将车辆减速时的动能转化为电能,回收入动力电源系统,而不是被摩擦浪费掉,这无疑相当于增加了动力电源系统的容量.在现有的技术条件下,对于提高电动汽车的续驶里程,这无疑是一个最直接有效的措施.文献[1]表明,在城市工况下,制动能量占总驱动能量的50%左右.因此,采用先进的能量回收技术,应用现代车辆设计方法和手段,对汽车的制动能量回收进行深入研究具有十分重要的意义.

Hyundai is currently the world is still widely used in internal combustion engine as a power source, consume large amounts of oil resources, emit large amounts of emissions, that global warming, air pollution, acid rain, freshwater resource crisis, resources, energy shortages, noise pollution. Power electric vehicles is based on renewable resources such as energy, neither of harmful gas emissions and no greenhouse gas emissions, noise is also small. It is the 21st century, clean, efficient and sustainable transport.
The key part is the electric vehicle power supply, power supply system is to determine the amount of stored energy driving range of electric vehicles, an important factor. But the current power supply technology is still the bottleneck of the development of electric cars, not a breakthrough. Driving range of electric vehicles can not meet the needs of users, if the vehicle kinetic energy during deceleration into electrical energy power supply system to income, rather than wasted by friction, which undoubtedly representing an increase of power supply capacity of the system. Under the conditions of the existing technology, for improving the driving range of electric vehicles, this is one of the most direct and effective measures. [1] showed that in urban conditions, the braking energy of the total driving energy of 50%. Therefore, the use of advanced energy recovery technology, application methods and means of modern vehicle design, vehicle braking energy recovery of in-depth study of great significance.
