电池堆
摘要：
本申请涉及一种电池堆，包括数个电池单元和至少一个拉紧元件，该数个电池单元堆叠在电池堆的第一堆叠端部与电池堆的第二堆叠端部之间，利用至少一个拉紧元件，用于夹紧电池单元的拉紧力能够引入到第一堆叠端部与第二堆叠端部之间，该至少一个拉紧元件包括第一局部区段和第二局部区段，第一局部区段起始于第一堆叠端部且在第二堆叠端部的方向上延伸，第二局部区段起始于第二堆叠端部且在第一堆叠端部的方向上延伸，其中，至少一个拉紧元件包括加载有压缩力的至少一个弹性元件，其将第一局部区段与第二局部区段连接，其特征在于，至少一个拉紧元件的第一局部区段和第二局部区段在两个堆叠端部之间的重叠区域中彼此重叠。
摘要（英）：

The application relates to a cell stack, comprising several cell units stacked between a first end of the stack of the cell stack and the second end of the stack of the cell stack and at least one tensioning element, with which a tensioning force for clamping of the cell units can be introduced between the first end of the stack and the second end of the stack, with the at least one tensioning element comprising a first partial section starting from the first stack end and extending in the direction of the second stack end and a second partial section starting from the second stack end and extending in the direction of the first stack end, where the at least one tensioning element comprises at least one resilient element being loaded with compression force which links the first partial section with the second partial section, characterized in that the first partial section of the at least one tensioning element and the second partial section of the at least one tensioning element overlap with each other in an overlapping area between the two ends of the stack.
