Abstract
A plurality of power source circuits is each configured to be able to selectively charge any one of a plurality of cells included in each of series cell groups by using a voltage across each of series cell groups. The plurality of discharge circuits are each configured to be able to discharge a capacity stored in each of series cell groups. A controlling circuit equalizes the states of the plurality of cells included in each of the series cell groups by using the plurality of power source circuits. The controlling circuit equalizes the states of the plurality of series cell groups by using the plurality of discharge circuits.
