Abstract
A battery control device calculates a chargeable/dischargeable electric power of a rechargeable battery at the timing after elapse of a predetermined period of time when a terminal voltage of the rechargeable battery changes by charging/discharging of the rechargeable battery during the predetermined period of time. The battery control device calculates a specific change amount of the terminal voltage caused by electric charge accumulation in the rechargeable battery after the elapse of the predetermined period of time when the charging/discharging of the rechargeable battery is performed. Further, the battery control device calculates an estimated target value of a current necessary for changing the terminal voltage to a predetermined target voltage or the terminal voltage after the elapse of the predetermined period of time by using the calculated specific change amount, and calculates chargeable/dischargeable electric power on the basis of the calculated estimated target value.
