Abstract: A battery control device (100) includes: a measurement unit (110) that individually measures an amount of discharging current of a discharging secondary battery among a plurality of secondary batteries which are independently charged and discharged; a time calculating unit (120) that calculates time required until the secondary battery has a constant battery capacity for each of the discharging secondary batteries on the basis of a discharging current rate for each of the secondary batteries which is calculated on the basis of the amount of discharging current, and an SOC of the secondary battery; a number calculating unit (130) that calculates an expected number of the secondary batteries, which become fully charged in the required time, on the basis of a charging current rate for each of the secondary batteries which is calculated on the basis of an amount of charging current of the charging secondary battery, an SOC of the secondary battery, and the required time, and calculates a total value of the expected number and the existing number of secondary batteries which are already fully charged; and a control unit (140) that determines whether or not to raise the charging current rate on the basis of the total value.
