Abstract
An assembled battery control system is provided with an assembled battery composed of a plurality of rechargeable battery packs connected in series, and a control unit for controlling the assembled battery. Each battery pack has a discharge unit. The control unit confirms the open-circuit voltage of each battery pack in the assembled battery after the assembled battery has been fully charged, determines a target voltage on the basis of the open-circuit voltage confirmation results for each battery pack in the assembled battery, causes the discharge unit to discharge each battery pack in the assembled battery that has an open-circuit voltage greater than the target voltage until the open-circuit voltage of each of said battery packs reaches the target voltage, fully charges the assembled battery again, discharges the assembled battery until a first predetermined level has been reached, and learns the capacity of each battery pack in the assembled battery.
