Zusammenfassung:	To provide a battery system capable of more efficiently detecting abnormality of a storage battery.SOLUTION: A battery system comprises a balance abnormality data acquisition unit and an operation data acquisition unit. The balance abnormality data acquisition unit acquires balance abnormality data on balance abnormality in at least one of voltage, current, and temperature between a plurality of battery cells included in a battery. The operation data acquisition unit, on the basis of the balance abnormality data, acquires operation data on the battery in which the balance abnormality is detected or balance control for suppressing the balance abnormality is executed.SELECTED DRAWING: Figure 1 【課題】蓄電池の異常をより効率的に検出することができる電池システムを提供することを目的とする。【解決手段】本実施形態による電池システムは、バランス異常データ取得部と、稼働データ取得部と、を備える。バランス異常データ取得部は、電池に含まれる複数の電池セル間における電圧、電流および温度の少なくとも１つのバランスの異常に関するバランス異常データを取得する。稼働データ取得部は、バランス異常データに基づいて、バランスの異常が検出された、または、バランスの異常を抑制するバランスが実行された、電池の稼働データを取得する。【選択図】図１
