PROBLEM TO BE SOLVED: To bring out the performance of a secondary cell to the maximum, and to suggest a control system of a secondary cell capable of balancing the life and safety at high level.SOLUTION: A control system of a secondary cell has a secondary cell, degree of deterioration determination means for determining the deterioration progress of the secondary cell, a controller for controlling at least the upper limit temperature of the secondary cell, and control value change determination means for controlling the change of the upper limit temperature. The control value change determination means determines the upper limit temperature of the secondary cell equal to or higher than an initial value, depending on the comparison results of the degree of deterioration of the secondary cell, and an assumed degree of deterioration.SELECTED DRAWING: Figure 1 【課題】本発明の第一の目的は、二次電池の性能を最大限に引き出すことである。また、この際に、寿命と安全性を高いレベルでバランスさせることが可能な二次電池の制御システムを提案することにある。【解決手段】二次電池と、前記二次電池の劣化進行を判断する劣化進行判断手段と、前記二次電池の少なくとも上限温度を制御する制御装置と、を有し、前記上限温度の変更を制御する制御値変更判断手段を有し、前記制御値変更判断手段は、前記二次電池の劣化度と、想定劣化度とを比較した結果に応じて、前記二次電池の前記上限温度を初期値以上とすることを特徴とする二次電池制御システム。【選択図】図１
