ABSTRACT:
If the voltage at any cell has become equal to or lower than a low-voltage decision-making voltage Vc1and the average voltage among cells calculated based upon the total voltage at a battery cell is higher than a predetermined voltage level, it is determined that a voltage variance among the individual cells has occurred and that a capacity adjustment is necessary.
