面向产业化的电动城市客车关键技术研究

Research on key technologies of industrialization-oriented electric city bus

电动汽车的产业化面临整车性能、成本和可靠性的问题,HFF 6112GK 50EV型电动客车作为国内第一款列入国家发展与改革委员会车辆产品公告的电动汽车,在关键技术的研究过程中充分考虑了这些问题.电动客车的关键技术包括动力系统、整车车身结构设计与分析、整车控制和能量管理系统等.对上述关键技术进行了研究,试验结果显示,在有效控制整车成本的基础上,该车动力性和经济性均超过合同规定的指标并达到国内先进水平,并且通过了5 000 km可靠性考核试验,目前正在接受公交工况的运行考核.

Industrialization of electrical vehicle is confronted of the problems of performance, cost and reliability. As the first type of electrical vehicle, HFF6112GK50EV bus is listed on the catalogue of vehicle product bulletin of National Development and Reform Committee. During the research of key technologies of such bus, the problems above are sufficiently considered. Key technologies of electric vehicle include power system, vehicle body structure design and analysis, overall vehicle control and energy management system etc. The experiment results of research on the above key technologies show the vehicle power performance and energy economic performance both exceed targets prescribed on the contract while the cost of overall vehicle is effectively controlled. This bus has passed 5 000 km reliability test and now is under test of public traffic operating condition.
