Electromagnetic Transient Simulation of Hybrid Electric Vehicles

The paper presents a procedure for modeling emerging hybrid and electric vehicle drive-trains in a transient simulation program. The benefit of such models is that they enable detailed studies to be carried out on the performance of the drive-train through detailed modeling of drive motors, power converters, and energy storage subsystems. The models also account for external mechanical forces on the vehicle, allowing tests such as acceleration, hill climbing and standard drive cycles to be done. A transient simulation model of a dual drive, series hybrid electric vehicle is developed and presented. The paper also presents simulation results for this vehicle and assesses their significance.
