纯电动城市客车动力系统匹配设计

Design of power system matching for pure electric city bus

电动汽车作为一种新型的交通工具,有助于促进交通模式的转变和交通运输设备制造产业的升级。尤其是对于城市客车而言,运行在复杂拥挤的道路中,工况恶劣,能耗大,污染严重,所以纯电动城市客车的研究显得尤为重要,其中尤以动力系统的设计为首要。根据纯电动城市客车对动力性的要求,文章对其进行了动力系统匹配设计。以12m大型城市客车为例,通过对其电机、传动系统、电池选型及参数计算,系统的设计了其动力系统,使其满足车辆动力性最优化需求。

As a new type of vehicle,electric vehicles help to promote the transformation of transportation modes and upgrade the transportation equipment manufacturing industry.Especially for urban passenger cars,they are running in complex and congested roads,with poor working conditions,high energy consumption,and serious pollution.Therefore,the research on pure electric city buses is particularly important,and the design of power systems is the most important.According to the requirements of the power of pure electric city bus,this paper carries out the power system matching design.Taking a 12m large-scale urban passenger vehicle as an example,the power system of the 12m large-scale urban bus is designed to meet the optimization needs of the vehicle's dynamic performance through the calculation of its motor,transmission system,battery selection,and parameters.
