<P>PROBLEM TO BE SOLVED: To provide a battery pack device capable of suppressing module capacity reduction due to variation in charged amount of each battery cell in a plurality of battery cells electrically connected in series, and further eliminating the necessity of a discharging device which becomes an external load. <P>SOLUTION: A battery pack device comprises: a plurality of battery cells 2 electrically connected in series; a cell balance adjustment part 31 for individually discharging the battery cells 2; a voltage detecting part 32 for individually detecting the voltage of each of the battery cells 2; a control part 36 for evenly adjusting the charged amount of each of the battery cells 2 by the cell balance adjustment part 31 according to a detected voltage of each of the battery cells 2 by the voltage detecting part 32; and a receiving part 34 for receiving a commanding signal to discharge for storage, which commands to perform a discharge for storage. In response to the reception of the commanding signal to discharge for storage by the receiving part 34, the control part 36 discharges each of the battery cells 2, which is in a fully charged state by the cell balance adjustment part 31, up to a charged amount for storage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
