For battery electric vehicle (BEV), electric motor is the only power source. The motor drive system in electric vehicle has many challenges like cost, weight, efficiency, detail torque speed characteristics, motor power rating. Accurate motor power rating prediction is very much necessary to fulfil the performance requirement of electric vehicle. Selection of oversized motor for Electric vehicle application results into overprice motor, more energy consumption and decline in vehicle range. Due to this there will expansion of battery size and increases the overall cost of vehicle. On the other hand, selection of undersized motor leads to poor vehicle performance that limits the drivability of vehicle. This paper gives detailed calculations of motor rating of electric motor. New approach is developed to predict the correct power rating of motor without affecting the desired vehicle performance. According to the requirement, accurate prediction of power rating of motor has been taken for cost efficient and upgradation the performance of motor. The work presented in this paper adopts a method of vehicle performance assessment on the basis of comparison with four different methods with new developed method. Traction motor is major & most expensive component of EV. Selection of motor play’s crucial role in the development of electric vehicle. Undersized and oversized motor results in rise in cost of motor which ultimately increases the cost of vehicle. But by using appropriate motor this cost been reduced up to 50-60% with performance enhancement.
