To provide a storage-battery system being less susceptible to noise.SOLUTION: According to an embodiment, a storage-battery system comprises a control device and a storage-battery device including a storage battery capable of being charged/discharged. The control device comprises a converter and a first processor. The converter supplies power to the storage battery. When receiving a contact signal for requesting charging to the storage battery, the first processor transmits a contact signal for turning ON a contactor that connects the converter and the storage battery together to the storage-battery device. The storage-battery device comprises a state-of-charge sensor, the contactor, and a second processor. The state-of-charge sensor measures a state-of-charge of the storage battery. The second processor transmits a contact signal for requesting charging to the storage battery to the control device on the basis of the state-of-charge, and, when receiving a contact signal for turning ON the contactor from the control device, turns ON the contactor.SELECTED DRAWING: Figure 1 【課題】ノイズの影響を受けにくい蓄電池システムを提供する。【解決手段】実施形態によれば、蓄電池システムは、制御装置と充放電可能な蓄電池を含む蓄電池装置とを備える。前記制御装置は、コンバータと、第１のプロセッサと、を備える。コンバータは、前記蓄電池に電力を供給する。第１のプロセッサは、前記蓄電池への充電を要求する接点信号を受信すると、前記コンバータと前記蓄電池とを接続する接触器をオンにさせる接点信号を前記蓄電池装置に送信する。前記蓄電池装置は、充電率センサと、前記接触器と、第２のプロセッサと、を備える。充電率センサは、前記蓄電池の充電率を測定する。第２のプロセッサは、前記充電率に基づいて、前記蓄電池への充電を要求する接点信号を前記制御装置に送信し、前記接触器をオンにさせる接点信号を前記制御装置から受信すると、前記接触器をオンにする。【選択図】 図１
