What is Battery Balancing and Does Your System Need It?
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.
