Most topologies in battery balancing systems are concerned with the system-level perspective of cells and equalizers. For a better understanding, consider the topologies as graphs in which the cells are nodes and each cell equalizer is regarded as an edge that acts as an energy transfer link between the cells (nodes) [1, 2].The active cell equalization systems …
The independent pack equalizer can balance battery packs independently, which means it can adapt to any structure of the lower cell equalizer [28,29]. This facilitates structure simplification and integration of the cell equalizer on a chip. Park et al. [28] introduced and compared a switch capacitor-based pack-to-pack equalizer and a flyback
