In summary, a BMS balances a battery stack by allowing a cell or module in a stack to see a different charging current than the pack current in one of the following ways:Removal of charge from the most charged cells, which gives headroom for additional charging current to prevent overcharging, and allows the less charged cells to receive more charging currentRedirection of some or nearly all of the charging current around the most charged cells, thereby allowing the less charged cells to receive charging current for a longer length of time [pdf]
