OCV is the voltage of the battery when it is not connected to any load or charger. A fully charged 12-volt battery should have an OCV of between 12.6 and 12.8 volts. If you measure the OCV of a battery and find that it is below this range, it may need to be charged or replaced. [pdf]

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]
