Comparative study of different electric propulsion system configurations based on IPMSM drive for battery electric vehicles

This paper presents a comparison between three different configurations of battery-powered electric vehicle (EV) propulsion system. Direct torque controlled (DTC) drive system of interior permanent magnet synchronous motor (IPMSM) is proposed. Bidirectional interleaved DC/DC converter is used to adapt the power flow between motor and battery in motoring and regenerative braking operation modes. Rule based power management and control (PMC) algorithm is adopted to manage and control the power flow between different drive systems. The drive and control system of IPMSM is implemented and simulated using MATLAB/SIMLINK. Furthermore, complete vehicle model is established and simulated using AVL CRUISE. Vehicle driving performance is calculated and presented in the simulation results to specify the potential of each propulsion system configuration. The best EV propulsion system is defined by comparing different configuration results to each other.
