Optimizing Battery Performance -Active and Passive Cell Balancing

Electric vehicles (EVs) are the transportation mode of the future. Due to their zero tailpipe emissions and minimal dependency on oil and its byproducts, EVs have gained popularity over the past ten years, with electric vehicle purchases increasing by 109% globally in 2021. Lithium-ion (Li-ion) battery packs are the primary energy source for the most recent completely electric vehicles, which has both benefits and drawbacks. Catastrophic casualties, such as poisonous smoke or fire, may result if the battery parameters are not maintained optimally in all circumstances. This paper's major goal is to show how to balance the voltages in each battery pack cell using a variety of cell balancing methods, such as active cell balancing and passive cell balancing. By preventing any cell from failing, this guarantees the battery pack's optimal performance. Active cell balancing is 23 percent more rapid compared to the results obtained from passive cell balancing.
