The braking system is always an important factor for any vehicle. Adaptive braking methods are This paper proposes the concept of cell balancing which can lookout the cells and battery from getting damage and increase the life of a battery. This paper comprises of three parts, first modeling of required parameters, second simulation of the model, and then the final results got from evaluation and simulation explained in detail. In case battery cells are connected in series they are unbalanced. The cell voltages are not the same. Variations in the State of Charge (SoC) of the Battery Cell, Cell Temperature, and Self Discharge Rate can cause imbalanced cells. Passive cell balancing and Active cell balancing are types of cell balancing. In this paper, only passive cell balancing is discussed with the simulation. The paper compares the performances of batteries also. This project is analyzed and evaluated in MATLAB/Simulink
