“…In contrast to an inefficient passive method above, the active battery balancing will transfer energy from the stronger cell/module to the weaker cell/module using a variety of balancing methods such as capacitor-based active balancing [5][6][7][8], inductor/transformer-based active balancing [9][10][11][12][13][14], and converterbased active balancing [15][16][17][18][19]. The active and passive balancing methods for lithium-based batteries have also been studied thoroughly in [1], [20][21][22][23][24]. In addition, a comparison between different balancing methods has been reported by [23][24][25][26][27][28], where the balancing methodology is classified depending on the number of switches, transformers, capacitors, inductors, diodes, modularity, complexity, reliability, cost, and so on.…”
