Abstract:
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.
