This paper is aimed at developing a design methodology of powertrain parameters matching for electric vehicles. The vehicles’ dynamics were studied in an attempt to find an optimal torque-speed profile for the electric propulsion system. This study reveals that the motor peak-power characteristic is associated with acceleration and grade ability of vehicles, and the motor rated-power characteristic is related with maximum vehicle velocity. Powertrain parameters of a model vehicle were also designed through theoretical calculation and simulation. To reduce the vehicle mass, a fixed gear ratio transmission is adopted, and the transmission ratio was optimized aimed to improve the energy efficiency. The simulation with chosen driving cycles indicate that parameters matching of the vehicle powertrain are reasonable and can meet the design specification of vehicle power performance and driving range capability.
