Motor Rating and Battery Pack Calculation for an EV-SUV

This paper focuses on the development of a methodology for calculating the optimal motor rating and battery pack capacity for an electric vehicle (EV). The proposed method takes into account various factors such as vehicle weight, aerodynamic drag coefficient, tire size, efficiency, and driving conditions such as gradient and acceleration. The methodology uses mathematical models to estimate the energy required to propel the vehicle over a specified distance and determine the optimal motor rating and battery pack capacity to meet the desired range and performance requirements, including ideal and practical characteristics. The study evaluates the impact of these parameters on the energy consumption, driving range, and acceleration of the vehicle. The results of the study show that the optimal motor rating and battery pack capacity depends on several factors such as vehicle weight, driving conditions, and desired performance. The proposed methodology and research findings could serve as a valuable reference for researchers and practitioners in the field of electric vehicle design and development. The mathematical model of the vehicle is designed in MATLAB and the methodology used is well-analyzed and simulated on the same platform, which are also validated with CANalyzer simulation experimental setup results.
