To ensure that the life of a storage battery reaches a target life.SOLUTION: A battery system according to an embodiment of the present invention includes a battery that can be used repeatedly, a battery control unit that controls the battery life by restricting a battery usage condition related to battery life deterioration, an estimation unit that calculates the estimated life of the battery obtained due to the restriction on the battery usage condition, and a restriction unit that obtains the shortage life that is insufficient for the target life of the battery on the basis of the calculated estimated life, and restricts and resets the battery usage condition of the battery control unit in the direction of reducing the shortage life.SELECTED DRAWING: Figure 1
【課題】本発明は、蓄電池の寿命を目標寿命まで確実に持たせることを目的とする。【解決手段】上記課題を解決するために、代表的な本発明の電池システムの一つは、繰り返し使用可能な電池と、電池の寿命劣化に係る電池使用条件を制約することにより、電池の寿命を制御する電池制御部と、電池使用条件の制約によって得られる電池の推定寿命を算出する推定部と、算出された推定寿命に基づいて、電池の目標寿命に不足する不足寿命を求め、不足寿命を削減する方向に、電池制御部の電池使用条件を制限して再設定する制限部とを備える。【選択図】図1
