摘要
对一种新型零排放电动汽车动力传动系统进行了研究,这种电动汽车以直接氢质子交换膜燃料电池为主要动力,以铅酸蓄电池为辅助动力。该电动汽车以巡航速度行驶时,由燃料电池供电,多余电量给蓄电池充电。在汽车加速、爬坡或高速运行等高功率需求工况时,由燃料电池和蓄电池同时提供动力。同时对该双能源电动汽车动力传动系统的参数进行了最佳匹配。最后对该电动汽车进行了仿真,结果表明动力传动系统的参数匹配是合理的,该电动汽车的动力性完全能满足设计指标要求。
The powertrain of a new type of zero emission electric vehicle is researched, which powered primarily by air-breathing proton exchange membrane (PEM )fuel cells with gaseous hydrogen as fuel,and with Lead-acid battery as assistant power.The fuel cell system provides power for the vehicle while the vehicle travel at a cruising speed,and the exceed power will charge for battery.The fuel cell and the battery system will together provide power to the vehicle during periods of peak power demand such as vehicle acceleration or traveling at a high constant speed.At the same time, the powertrain parameter of this fuel cell vehicle are matched reasonably.At last, the dynamic of an electric vehicle is simulated, and the result shows that the dynamic performance perfectly meets the need of the design target.
