To provide an advantageous technique for suppressing a secondary disaster caused by a stationary battery device which stores power supplied from an electric system.SOLUTION: The power system includes: an electric system which supplies power; and a stationary battery device which stores power supplied from the electric system. The battery device includes: a battery which includes a battery part which stores power supplied from the electric system, and a detector which detects the vibration of the battery part; and a control unit which controls a system connection between the electric system and the battery to disconnect the battery from the electric system, if the magnitude of the vibration of the battery part detected by the detector exceeds a threshold.SELECTED DRAWING: Figure 3 【課題】電力系統から供給される電力を蓄電する定置型のバッテリ装置に起因する２次災害を抑制するのに有利な技術を提供する。【解決手段】電力を供給する電力系統と、前記電力系統から供給される電力を蓄電する定置型のバッテリ装置と、を備えた電力システムであって、前記バッテリ装置は、前記電力系統から供給される電力を蓄電するためのバッテリ部と、前記バッテリ部の振動を検知する検知器と、を内包するバッテリと、前記検知器で検知される前記バッテリ部の振動の大きさが閾値を超えた場合に、前記バッテリを前記電力系統から解列するように、前記電力系統と前記バッテリとの系統接続を制御する制御部と、を含むことを特徴とする電力システムを提供する。【選択図】図３
