The acceptance of electric vehicles (EVs) is rapidly growing in today's era, driven by the imperative to curtail carbon emissions and embrace environmentally friendly alternatives. Consequently, profound significance is attached to researching energy regeneration systems within EVs. This paper focuses on a simulation study involving an integrated electric vehicle (EV) model and a regenerative braking system (RBS). The EV model was meticulously crafted using MATLAB Simulink to investigate the impact of the RBS on recharging the battery with recaptured energy. Furthermore, the study delved into comprehending how the size and weight factors influence the RBS performance. The study leveraged a 72 V Lithium-ion battery model, valued for its substantial capacity and charging efficiency. Employing Simulink's driving cycle sources, the simulation accurately mirrored real-world scenarios. The pivotal parameters scrutinized in this simulation encompassed the magnitude of current replenishing the battery and the battery's State of Charge (SOC) percentage. The results of this study showed that a good design for electric vehicles, focused on putting more energy back into the battery, needs to be heavier, more aerodynamic, and have a smaller front end.
