To charge battery properly.SOLUTION: A battery control device 60 includes: a discharge controller 63 which controls discharge from a battery 52; a charge controller 65 which controls charge to the battery 52; and a storage 61 which stores a target charge capacity C11 to be charged to the battery 52. The discharge controller 63 is configured to be capable of performing at least discharge from the battery 52 to a lower limit SOC 72 determined in advance. The charge controller 65 is configured to start count of a charge capacity at timing at which a present SOC 70 of the battery 52 becomes equal to the lower limit SOC 72 when a charge is started in a state where the present SOC 70 of the battery 52 is lower than the lower limit SOC 72, and to end the charge to the battery 52 once the charge capacity having been charged after starting the count becomes equal to the target charge capacity C11 stored in the storage 61.SELECTED DRAWING: Figure 5 【課題】バッテリーへの充電を適切に行う。【解決手段】バッテリー制御装置６０は、バッテリー５２からの放電を制御する放電制御部６３と、バッテリー５２への充電を制御する充電制御部６５と、バッテリー５２へ充電する目標充電容量Ｃ１１を記憶する記憶部６１と、を備えている。放電制御部６３は、予め定められた下限ＳＯＣ７２までバッテリー５２からの放電を少なくとも実施可能に構成されている。充電制御部６５は、バッテリー５２の現在ＳＯＣ７０が下限ＳＯＣ７２よりも低いＳＯＣから充電が開始されたとき、バッテリー５２の現在ＳＯＣ７０が下限ＳＯＣ７２になったタイミングで、充電容量のカウントを開始し、カウントが開始されてから充電された充電容量が、記憶部６１に記憶された目標充電容量Ｃ１１になったときに、バッテリー５２への充電を終了するように構成されている。【選択図】図５
