Embodiment Construction

[0073] For example, if figure 1 and Figure 8 As shown, battery 1 has a housing 2 and a plurality of battery cells 3 . The housing 2 has at least two housing walls 5 facing one another. The battery cells 3 are arranged one behind the other in the stacking direction 4 and are arranged in the housing 2 . exist figure 1 and Figure 8 In the shown end position 6 , the battery unit 3 has been completely inserted into the housing 5 in an insertion direction 7 transverse to the stacking direction 4 . In each case, the housing 2 shown has two housing walls 5 facing each other, namely two housing walls 5 positioned opposite each other in the stacking direction 4 , and transverse to the stacking direction 4 and transverse to the stacking direction 4 . Insertion direction 7 of the two housing walls 5 positioned opposite one another. Battery 1 also has at least one intermediate part 8 which is arranged in housing 2 between housing walls 5 . The corresponding intermediate part 8 is he...

Abstract

The invention relates to a storage battery (1) having a housing (2) in which a plurality of battery cells (3) are arranged, said battery cells being arranged one after the other in a stacking direction (4). Simplified production of the storage battery (1) is achieved and / or the risk of damaging the battery cell (3) is reduced, wherein at least one variable intermediate part (9) is arranged in thehousing (2); after the battery cell (3) is arranged in the housing (2), the battery cell (3) changes from a first state (10) to a second state (11), and the variable intermediate piece (9) has a greater thickness (13) in the second state (11) than in the first state (10). The invention also relates to a method for producing such a battery (1).

Description

technical field [0001] The invention relates to a battery having a plurality of battery cells which are arranged one behind the other in a stacking direction and which are accommodated in a housing which has two housing walls facing each other. The invention also relates to a method of producing such an accumulator. Background technique [0002] Batteries that are charged and discharged during operation, also known as accumulators, are also playing an increasingly important role in mobile applications. Such batteries are also increasingly used in vehicles. [0003] Batteries usually have a plurality of battery cells which are arranged one behind the other in the stacking direction. Such a storage battery is known, for example, from European patent EP 2 866 289 A1. This document proposes a mode of construction for accumulators in which successive accumulator cells can have different dimensions and are in each case laterally provided with porous separating elements.
