Lithium battery packs have revolutionized how we power our devices by providing high energy density and long-lasting performance. These rechargeable batteries are composed of lithium ions, which move between the anode and cathode during charge and discharge cycles.
Moreover, a lithium-ion battery pack must not be overcharged, therefore requires monitoring during charging and necessitates a controller to perform efficient charging protocols [13, 23, 32, 143 - 147].
However, a battery pack with such a design typically encounter charge imbalance among its cells, which restricts the charging and discharging process . Positively, a lithium-ion pack can be outfitted with a battery management system (BMS) that supervises the batteries' smooth work and optimizes their operation .
