Performance and reliability experiments on BJD-6100EV electric buses， jointly developed by Beijing Institute of Technology and Beijing Public Transport Company， are introduced. Output power model of battery pack is established and maximum output power is analyzed. A permanent magnetic direct current (PMDC) motor with enhanced windings is developed for the bus. Torque-speed characteristics of the motor are modeled and performance of electric bus is analyzed. Computational method of the range of electric bus is proposed and discussed. Experiments show that electric bus can realize design requirements. Computational methods are verified with the help of field test. It is expected that design and computation method will provide helpful reference to development of electric vehicles.
