Study of Different Electric Vehicle Propulsion System Configurations

This paper presents a study of an electric vehicle (EV) with two different drive systems and three available electric motors (EMs) configurations. The EMs are BLDC (Brushless Direct Current) motors combined with a proportional-integral controller (PI). The vehicle power demand is divided between the drive systems through rules based vehicle power management control (PMC) that aims to reduce the lithium-ion battery discharges during the Brazilian urban driving cycle NBR6601. The results indicate the potential of each simulated configuration and the combination drive system/EM in which present the lower battery discharge. Each EV configuration is compared and the best configuration is defined.
