| Zusammenfassung: | The invention relates to an electrical energy storage (1). The electrical energy storage has a plurality of battery cells (2) arranged adjacent to each other in a stacking direction (3), an end plate(7) arranged on an end side of the battery cells (2) in the stacking direction (3), and a tensioning band (12). At least one of the end plates (7) having a rib structure (9), The tensioning band actson the end plates (7) such that the end plates interact in the stacking direction (3). The increase in the service life and/or efficiency of the energy store (1) is achieved in that an intermediate element (15) is arranged between the tensioning belt (12) and at least one of the end plates (7), on which intermediate element the tensioning belt (12) lies flat. The invention also relates to a devicehaving an intermediate element (15) and such a tensioning band (12) fastened thereto.
本发明涉及一种电能量存储器(1)，其具有在堆叠方向(3)上彼此相邻设置的多个蓄电池单元(2)以及在堆叠方向(3)上设置在蓄电池单元(2)的端侧的端板(7)，以及张紧带(12)，其中端板(7)中的至少一个具有肋片结构(9)，所述张紧带作用于端板(7)，使得所述端板沿堆叠方向(3)相 |
