However, such a gap filler 22 has the disadvantage that on the one hand it is relatively expensive and leads to a significantly higher weight of the battery device 10 and on the other hand it is not as thermally conductive as metal, so that a thick gap-filling layer instead impairs the cooling efficiency
However, this leads to and refers to figure 1 Same drawbacks as explained about using gap fillers

Abstract
The invention relates to a battery assembly method for providing a battery device (30) having at least one battery module (32), a cooling device (36) and a frame (38. Herein, for the battery module (32) fixed on the first side (36a) of the cooling device (36), the battery module (32) is bonded in the module support area (44a) of the first side (36a) without fixing the frame (38) At the cooling device (36), the cooling device (36) has a separating element (44) providing a first side (36a), which has an edge region (44c) and a transition region (44b) connecting the edge region (44c ) with the module bearing area (44a), the separating element (44) is elastically deformable at least in the transition area (44b), after bonding the battery module (32), the frame (38) is placed such that the frame (38) At least one portion (38b) lies on an edge region (44c) of the separating element (44).
Description
technical field [0001] The invention relates to a battery assembly method for providing a battery device having at least one battery module, a cooling device for cooling the at least one battery module, and a frame, the at least one battery module being fixed on a first side of the cooling device, The frame is fixed to at least one battery module. The invention also relates to a battery device for a motor vehicle. Background technique [0002] Battery systems known from the prior art for motor vehicles, in particular high-voltage batteries, typically have a battery housing in which individual battery modules are accommodated. The battery housing may comprise a housing bottom and a frame that provides to some extent the side walls of the housing, and optionally also other dividing walls, to separate the receiving areas of the individual battery modules from each other and to provide Fixability of battery modules. A cooling device for cooling the battery modules is typicall...
