摘要
由于续驶里程的限制,目前为止,纯电动汽车比较适合在城市内短距离使用,同时需要对城市行驶有较强的适应性。文章基于对美国城市驾驶循环工况的分析,提出了纯电动汽车关键零部件的选型方法及要求,并根据该方法以及整车参数,对电驱动系统的峰值工作特性、能源存储系统的容量以及充放电特性等参数进行了合理的选择。最后对整车关键部件的选型结果进行了仿真验证。结果表明,所选择的方法满足设计要求,该方法可以作为城市行驶纯电动汽车动力系统选型的一种参考方法。
Due to the limited of duration distance, PEV is more suitable for short- distance-driving in cities. Based on the analysis of UDDS,we put forward the selecting and calculating method of PEV key components. Through this method and the whole vehicle parameters,we select electric drive system＇s peak characteristic and energy storing system＇s eapacity and charge/ discharge characteristic reasonably. We also simulate the selection result of components. The results show that the selection plan can satisfy the requirement of design. Therefore, the type selection method may be used as one of city-driving PEV power train system design method.
