To reduce the inconsistency of battery packs, this study innovatively proposes an integrated active balancing method for series-parallel battery packs based on LC energy storage.
The energy storage device only needs one inductor, and the balanced energy can be transferred between any cell or unit in the series-parallel battery pack. Combining diodes and MOSFETs to form a switching array reduces the cost of the equalization topology while increasing the fault tolerance of the control signal.
But the real picture is complicated by the presence of cell-to-cell variation. Such variations can arise during the manufacturing process—electrode thickness, electrode density (or porosity), the weight
