using the same PWM signals during the balancing process. This allows for the balancing of both adjacent and non- adjacent cells. Half of the paths have a single capacitor between two cells, while the other half have two capacitors. The total number of capacitors used in the balancing circuit is 2 N, where N is the number of series-connected cells.

Cells within a battery pack may have more varying capacities, which means they can store various amounts of energy. This diversity in capacity can cause an uneven distribution of energy throughout the pack, resulting in some cells becoming fully charged or discharged before others.
To illustrate this, let’s take the example of a battery pack with four cells connected in series, namely Cell 1, Cell 2, Cell 3, and Cell 4. Before balancing, the SOC level of cells L1,L2,L3, and L4 were 40%, 60%, 80%, and 100%, respectively.
A balanced battery pack is achieved when all the cells reach the same SOC at some stage during their operational cycle (Andrea, 2010). to restore equilibrium. Common balancing methods include passive and active techniques. resistors to dissipate the excess energy as heat. Active balancing, also known as non-dissipative balancing,
