Performance assessment of battery-powered electric vehicle employing PMSM powertrain system

Battery-powered electric vehicle (EV) is considered as a promising solution for environmental pollutions and energy crises. Besides, the advances in traction motors and battery technologies allow the development of efficient, reliable and economical electrical propulsion system (EPS) for battery-powered EVs. Where, permanent magnet synchronous motor (PMSM) is mostly used in EVs because of its good performance compared to other used motors. Moreover, Lithium-ion batteries are mostly used to provide the motoring power due to their high energy densities and long lifetimes. In this paper, the driving performance of a battery-powered EV powertrain system is evaluated. The proposed EV propulsion system implements PMSMs as its main traction system. The design and simulation results of the proposed powertrain system are presented. A co-simulation platform based on AVL-Cruise and Simulink is established, and a simulation of the whole EV model is conducted. Using rule-based power management and control (PMC) strategy to manage and control the power flow between rear and front EV drive systems. Vehicle performance under the new European driving cycle (NEDC) is calculated and presented in the simulation results to specify the potential of the proposed system. The simulation results demonstrate that the proposed powertrain system match the design specification of EV dynamic performance and driving range capability.
