    摘要： In a battery device including a battery pack in which a plurality of cells are connected in series, there are provided a battery control circuit or a battery device capable of eliminating a fluctuation in the voltage or charged state which can occur between the cells, or preventing the cells from being maintained in an over-charged state for a long period.
    A plurality of cell groups 112 each including a plurality of cells 111 are connected in series to form a battery pack 110. Cell control means 121 provided to the respective cell groups operate with electricity supplied from the cell groups allocated thereto so as to monitor and control the state of the cells of the cell group. Battery pack control means 150 controls the cell control means based on information from the plurality of cell control means. When there is a cell group of which the charged state is higher than a predetermined charged state, the battery pack control means allows operation of the cell control means that monitors the cell group having the high charged state to be continued when charging and discharge of the battery pack stop to thereby discharge the cells to decrease the charged state.
