Mathematical Modelling And Simulation-Based Evaluation Of Electric Powertrain Performance

Source abstract

This study presents a mathematical modeling and simulation-based framework for evaluating the electric powertrain performance of mini passenger electric vehicles under standardized driving conditions. The framework integrates vehicle longitudinal dynamics, electric motor characteristics, transmission behavior, and battery performance using MATLAB/Simulink. The New European Driving Cycle (NEDC) and Modified Indian Driving Cycle (MIDC) are used for detailed simulation and graphical analysis, while FTP-75 results are included in the comparative performance tables. The model considers kerb weight, gross vehicle weight, rolling resistance coefficient, aerodynamic drag coefficient, wheel radius, gear ratio, drivetrain efficiencies, and battery capacity. The simulations compare tractive-force demand, motor speed and torque, battery power and current, state of charge, and energy consumption. The results show that the selected driving profile significantly influences aerodynamic loading, battery demand, and energy performance. NEDC produces comparatively higher high-speed loading, whereas MIDC represents repeated acceleration and deceleration conditions relevant to Indian driving environments. The developed framework provides a repeatable basis for evaluating powertrain behavior and comparing vehicle configurations under different standardized cycles.
