There are a variety of ways to keeps a battery pack properly balanced. This article introduces the concept of active and passive cell
Balancing can be active or passive. In active balancing, the balancer circuit enables transfer of charge between different cells of the battery, i.e., transferring energy from cells with a higher charge to cells with a lower charge. The term battery regulator typically refers only to devices that perform passive balancing. A full BMS might include active balancing as well as temperature m

Balancing is a critical process in the management of LiFePO4 batteries that ensures each cell within the battery pack maintains uniform voltage levels. It involves redistributing charge among individual cells to prevent overcharging of high-voltage cells and over-discharging of low-voltage cells. This process helps in
Active Battery Balancing. In active battery balancing, a charging current is intentionally routed between a high SOC cell and a lower SOC cell. This is done with an interconnection as in the passive case, but the charge is intentionally directed between specific cells rather than allowing the charge to balance naturally.
