Provided are a battery control device which can estimates an SOC of a battery with a high accuracy, and an electric motor vehicle system. The battery control device (190) includes a feature amount calculation unit (152) which calculates a feature amount indicating a charging/discharging pattern of the battery, a first charging state amount calculation unit (151-1) which calculates a first charging state amount (SOCi) of the battery on the basis of a first battery state amount, a second charging state amount calculation unit (151-2) which calculates a second charging state amount (SOCv) of the battery on the basis of a second battery state amount, and a third charging state amount calculation unit (151-3) which calculates a third charging state amount (SOC(t)) on the basis of the feature amount, the first charging stage amount, the second charging stage amount.
