Development of electric vehicle with permanent magnet synchronous motor and its analysis with drive cycles in MATLAB/Simulink

Abstract

The conventional fuel dominant automotive market has been challenged by electric vehicles (EVs) in both commercial and private vehicles segment. The rising fuel prices, stringent emission norms, government incentives, and increasing awareness towards global warming has publicized EV as the future of the automobiles. New rare earth permanent magnet materials and advanced electronic controllers have made the traction motors more compact and energy efficient. EV motors combined with the advanced battery technology has helped in ruling out range anxiety from people’s mind. Modeling and simulation of electric vehicle reduces cost and ramps up the development process. In this paper simulation model of electric vehicle is developed for traction application with model-based design approach using MATLAB/Simulink. This includes a dynamic vehicle model running on two different drive cycles, extra urban driving cycle (EUDC) and new european driving cycle (NEDC). The vehicle model takes velocity as input from the drive cycle and generates the required torque and power. The permanent magnet synchronous motor (PMSM) model takes this torque as input reference torque and produce the power and torque. The simulated results of vehicle model are validated by analytical calculated results. The error obtained are under 0.05%. The vehicle performance with variations in inclination angle and driving cycle is also observed and analysed. This model is used to observe torque, power, energy consumption and range of the vehicle.
