Embodiment Construction

[0068] figure 1 An embodiment of a battery module 1 according to the invention is shown schematically.

[0069] The battery module 1 has a plurality of battery elements 2 which can be electrically connected to one another in series and / or in parallel.

[0070] In particular, the battery element 2 is designed here as a medium-temperature battery element.

[0071] The battery element 2 is here accommodated in a battery module housing 3 of the battery module 1 .

[0072] The battery module housing 3 here has a plurality of housing walls 4 .

[0073] according to figure 1 In the illustrated embodiment, the battery module housing 3 surrounds the plurality of battery elements 2 at the four sides 40 of the battery module 1 .

[0074] Furthermore, it is of course also possible that the battery module housing 3 encloses the battery element 2 only on two sides 40 , for example.

[0075] The housing wall 4 can include cooling channels 5 , wherein the cooling channels 5 are designed ...

Abstract

The invention relates to a battery module having a plurality of battery elements (2), wherein the battery elements are housed in a battery module housing (3) of the battery module (1), wherein the battery module housing (3) having at least one housing wall (4), the housing wall comprising a cooling channel (5) configured for tempering fluid flow, and the housing wall (4) additionally having at least one compensation structure (6) the compensation structure is configured to compensate for a mechanical load, wherein the compensation structure (6) has a first compensation element (81) and a second compensation element (82), wherein the first compensation element ( 81) arranged in such a manner as to be movable relative to the second compensating element (82) along the compensation direction (83), and additionally, the compensating direction (83) is also associated with the housing wall (4) The longitudinal direction (41) is arranged in an angle (9), wherein the angle (9) has a value of 10to 80 degrees.

Description

technical field [0001] The invention is based on a battery module having a plurality of battery elements of the type according to the independent claim. [0002] The object of protection of the invention also includes the use of such a battery module. Furthermore, the invention also relates to a battery module housing. Background technique [0003] It is known from the prior art that a battery module can consist of a plurality of individual battery elements which can be electrically conductively connected to one another in series and / or in parallel. [0004] Especially in electric vehicles (EV), hybrid electric vehicles (HEV) or plug-in hybrid electric vehicles (PHEV), battery modules are used which comprise high-energy and powerful lithium-ion battery elements or lithium Polymer battery elements, the battery module preferably has approximately 100 battery elements in order to be able to meet the increased demands on driving performance. In addition, battery modules can a...
