PROBLEM TO BE SOLVED: To provide a battery control device and a battery pack which restrict the input/output power of a battery cell by using temperature information of a battery cell and temperature information different from the temperature information of the battery cell.SOLUTION: In a battery system 10, when a difference between temperature information of a battery cell at a time of starting a vehicle and temperature information inside a housing in which the battery cell is housed is larger than a predetermined value, and the temperature information of the battery cell is higher than the temperature information inside the housing in which the battery cell is housed, the battery control device (BMS) 110 restricts input/output power of the battery cell.SELECTED DRAWING: Figure 4
【課題】電池セルの温度情報と、電池セルの温度情報とは異なる温度情報を用いて、電池セルの入出力電力を制限する電池制御装置及び電池パックを提供する。【解決手段】電池システム10において、電池制御装置(BMS)110は、車両起動時の電池セルの温度情報と電池セルが収納される筐体内部の温度情報との差が所定値よりも大きい場合であって、かつ、電池セルの温度情報の方が電池セルが収納される筐体内部の温度情報よりも高い場合に、電池セルの入出力電力を制限する。【選択図】図4
