A Wide Component Sizing and Performance Assessment of Electric Drivetrains for Electric Vehicles

The main purpose of this paper is to provide a wide parametric design procedure for drivetrain system of electric vehicles (EVs). This method, for a given vehicle’s specifications, can determine both the ratings and maximum capabilities of the powertrain. The ratings include motor power, torque, speed, and battery capacity. In the proposed methodology, the ratings consider the maximum velocity and maximum acceleration rate of the vehicle to achieve the heaviest road conditions. The validation of the proposed methodology is discussed with case study: Nissan-Leaf2015 E-Car. The performance of the vehicles is simulated and assessed with two different driving cycles (Urban Dynamometer Driving Schedule (UDDS) and high way ARTEMIS MW-130 and is validated through extensive simulations at 100% ratings and up to 140% of power ratings.
