To provide an improved power storage system and method for extending the life of a vehicular battery pack.SOLUTION: A method for optimizing the operation life of a power storage system that includes a battery pack including a plurality of battery cells includes the steps of: measuring temperature (T) of the battery pack by a sensor unit; measuring at least one other parameter indicating an index of the operation life of the battery pack; detecting whether or not the parameter reaches a predetermined threshold indicating a state where the battery pack approaches at the end of expected operation life; and, if the parameter reaches the threshold, initiating heating of the battery pack to increase the temperature (T) of the battery pack to a predetermined value (T1).SELECTED DRAWING: Figure 3

    【課題】車両のバッテリパックの寿命を延長させる改良された電力貯蔵システム及び方法を提供する【解決手段】複数のバッテリセルを有するバッテリパックを備えた電力貯蔵システムの動作寿命を最適化する方法であって、センサユニットによってバッテリパックの温度(T)を測定するステップと、バッテリパックの動作寿命の指標を表す少なくとも1つの他のパラメータを測定するステップと、期待される動作寿命の末期にバッテリパックが近づいた状態にあることを示す所定の閾値に前記パラメータが達したか否かを検出するステップと、前記パラメータが前記閾値に達した場合、バッテリパックの加熱を開始して、バッテリパックの温度(T)を所定値(T1)に上昇させるステップと、を備える。【選択図】図3
