Abstract Industrialization of electrical vehicle is confronted of the problemsof 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 performanceand 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.
