摘要： PROBLEM TO BE SOLVED: To solve the problems in which temperature distribution in a lamination direction of battery cells becomes ununiform because thermal conduction in the lamination direction of the battery cells is small in comparison to thermal conduction in an electrode surface direction of the battery cells orthogonal to the lamination direction, and charging and discharging performance of the battery cells is reduced because degradation degrees accompanying charging and discharging of the battery cells become different between a battery cell part exposed to high temperature and a battery cell part at low temperature.SOLUTION: Endothermic means having an endothermic function is arranged on a surface in a direction orthogonal to a lamination direction in which battery cells are laminated (in other words, a surface parallel to the lamination direction), and a plurality of battery cells and the endothermic means are thermally connected. Since the endothermic means and each of the battery cells are thermally connected under the substantially same condition, heat generated in each battery cell is absorbed by the endothermic means at the rate of the same degree and ununiformity of the temperature distribution of each battery cell can be suppressed.
摘要翻译：要解决的问题：为了解决电池单元的层叠方向的温度分布变得不均匀的问题，因为与电池单元的电极表面方向的热传导相比，电池单元的层叠方向的热传导小到层叠方向，并且由于伴随着高温暴露的电池单元部分和低温下的电池单元部分而伴随着电池单元的充电和放电的劣化程度的不同，电池单元的充放电性能降低。解决方案：吸热具有吸热功能的装置被布置在与层叠电池单元的层叠方向（换句话说，与层叠方向平行的表面）的正交方向的表面上，并且多个电池单元和吸热装置是热的连接的。由于吸热装置和每个电池单元在基本相同的条件下热连接，所以每个电池单元中产生的热量由吸热装置以相同程度的速率吸收，并且每个电池单元的温度分布不均匀可以被压制
