In MATLAB, modeling a battery-driven electric vehicle (EV) with regenerative braking operation involves creating a comprehensive simulation environment that captures the dynamic interactions between the vehicle, its battery system, and the braking system. The model accounts for factors such as vehicle dynamics, battery characteristics, and regenerative braking efficiency. MATLAB provides tools for designing the vehicle dynamics model, simulating battery behavior, and implementing regenerative braking control algorithms. Engineers can analyze the energy flow within the system, evaluate the impact of regenerative braking on energy efficiency and battery health, and optimize control strategies to maximize energy recovery during braking events. Through MATLAB simulations, researchers can explore different scenarios, assess performance under varying driving conditions, and develop strategies to enhance the overall efficiency and sustainability of battery-driven electric vehicles with regenerative braking capability.
