To compare the key performance of different drive systems in battery electric vehicles, a study on the motor drive system was carried out based on the same vehicle parameters and companyprovided experimental data for variablewinding permanent magnet synchronous motors. Using the elitepreserving genetic algorithm and dynamic programming theory, the speed ratios for both singleand twospeed AMT drive systems were designed and optimized. These methods were applied to optimize the system speed ratios, and to design the dynamic and economic aspects of the winding switching process in variablewinding permanent magnet synchronous motors. The simulation results show that in terms of dynamics, the twospeed AMT drive system offers the best acceleration performance. In terms of economy, the variablewinding permanent magnet synchronous motor drive system achieves the lowest energy consumption per 100 km.
