摘要
新能源汽车是节能、环保汽车发展的重要方向,能量回收技术是新能源汽车提高能量经济性的重要手段。能量回收主要是在滑行和制动情况下,通过电机作发电机,将车辆部分多余的动能转化为电能,反向流入电池储存加以利用。文章以插电式混合动力汽车(PHEV)为研究对象,针对滑行能量回馈方式进行方案设计,试验验证不同方案对新欧洲标准驾驶循环(NEDC)工况下电耗的影响,并分析差异的原因,为车型的匹配标定提供方向。
New energy vehicles is one of the important parts for environment protection in the future,and the energy feedback technology can be a significant method to make new energy vehicles run efficiently. Energy feedback technology contains two ways, one is coasting, the other is braking feedback. During energy feedback, the mechanical energy can be translated to electric energy by motor, the energy is stored in the battery for further consumption. Based on plug in hybrid electric vehicle(PHEV), this article is focused on designing various coasting energy feedback methods, tests the electricity consumption at new European driving cycle(NEDC), analyzes the differences among various coasting methods, and provides the direction for calibration.
