Design, Modeling and Simulation of an Electric Vehicle System

The switched reluctance motor is a strong candidate for electric/hybrid vehicle applications primarily because of its high power density, good efficiency and high-speed capability. The motor drive for an EV is desired to have a wide speed range capability to eliminate the gears. A 4:1 speed range of the motor in the constant power region results in good performance of the system.

The paper will report the design of an electric vehicle system using a switched reluctance motor drive. A system level simulation tool for electric vehicles using the Matlab-Simulink platform will also be presented. The paper will discuss the analytical and simulation models for each of the key system components of an EV, which are the motor, controller, battery and the drivetrain.
