Abstract
A battery control device includes: a measurement unit that individually measures an amount of discharging current of each discharging secondary battery of discharging secondary batteries among a plurality of secondary batteries which are independently charged and discharged; a time calculating unit that calculates time required for discharging said each discharging secondary battery until said each discharging secondary battery reaches a constant battery capacity based on a discharging current rate for said each discharging secondary battery which is calculated based on the amount of discharging current, and a state of charge (SOC) of said each discharging secondary battery; a number calculating unit that calculates an expected number of charging secondary batteries among said plurality of secondary batteries, which become fully charged in a required time, based on a charging current rate for each charging secondary battery of charging secondary batteries among said plurality of secondary batteries which is calculated based on an amount of charging current of said each charging secondary battery, a SOC of said each charging secondary battery, and the required time, and calculates a…
