The purpose of cell balancing in a battery pack is to equalize the State of Charge (SOC) among all individual cells in the pack, ensuring that each cell operates within its safe and optimal operating range. Battery packs consist of multiple cells connected in series and parallel to achieve the desired voltage and capacity. Due to manufacturing variations, temperature gradients, and aging effects, individual cells in a pack can have slightly different capacities, internal resistances, and self-....
