To shorten a charge time to a battery. A battery control device includes: a discharge controller which controls a discharge from the battery; and a charge controller which controls a charge to the battery. The discharge controller is configured to be capable of performing at least a discharge from the battery to a lower limit SOC determined in advance which is higher than a pre-charge SOC determined in advance. The charge controller is configured to charge the battery at a second charge rate that is lower than a first charge rate determined in advance when a present SOC of the battery is lower than the pre-charge SOC and to charge the battery at the first charge rate when the present SOC of the battery is equal to or higher than the pre-charge SOC.
