In this study, a performance simulator for the electric vehicle with two-speed synchro-type transmission was developed. Using the simulator, 2-speed transmission system with selected shifting points and gear ratios were compared with the fixed gear ratio system, and the reduction in the drive motor capacity and the acceleration performance and fuel economy were evaluated. It is found from the simulation results that the maximum velocity, climbing, fuel economy and acceleration performance are improved with 2-speed synchro-type transmission for the same motor specification, and the EV has similar performance with reduced maximum motor torque.
