PROBLEM TO BE SOLVED: To provide a battery system 1 having a long cycle life, which allows a battery 10 to exhibit its original performance.SOLUTION: A battery system 1 comprises: a secondary battery 10; and a control part 21 which controls the charge and discharge of the secondary battery 10. The control by the control part 21 has a normal mode and a recovery mode. The discharge rate in the recovery mode is 1-30% of that in the normal mode.SELECTED DRAWING: Figure 1 【課題】電池１０の本来の性能を発揮できる、サイクル寿命の長い電池システム１を提供する。【解決手段】電池システム１は、二次電池１０と、二次電池１０の充放電を制御する制御部２１と、を具備し、制御部２１による制御が、通常モードと、回復モードと、を含み、回復モードの放電レートが、通常モードの放電レートの、１％以上３０％以下である。【選択図】図１
