Embodiment Construction

[0044] figure 1 An embodiment of a battery module 1 is shown schematically.

[0045] The battery module 1 here comprises at least one battery cell 2 , in particular a lithium-ion battery cell.

[0046] Furthermore, the battery module 1 includes a cooling plate 3 . In this case, the cooling plate 3 is thermally connected to at least one battery cell 2 .

[0047] In order to increase the thermal conductivity between the at least one battery cell 2 and the cooling plate 3 , a thermal equalization layer 4 is arranged between the at least one battery cell 2 and the cooling plate 3 .

[0048] In this case, the thermal equalization layer 4 is formed from a base material 5 . The base material 5 of the thermal equalization layer 4 is preferably formed here from an electrically insulating material 7 . For example, the base material can be formed from silicone or epoxy and can additionally comprise a thermally conductive filler material in order to increase the thermal conductivity. ...

Abstract

The invention relates to a battery module comprising at least one battery cell (2), in particular a lithium-ion battery cell, and a heat-conducting connected to the at least one battery cell (2) cooling plate (3), wherein between the at least one battery cell (2) and the cooling plate (3) further arranged to increase the thermal conductivity between the at least one battery cell (2) and the cooling plate (3) formed thermal compensation layer (4), wherein the thermal compensation layer (4) is formed of a base material (5) and further comprises at least one plastic (6) which has a melting temperature above a temperature of 50 DEG C.

Description

technical field [0001] The invention proceeds from a battery module of the type according to the independent claims. Furthermore, the invention also relates to the use of said battery module. Background technique [0002] It is known from the prior art that a battery module can consist of a plurality of individual battery cells, which can be electrically conductively connected to one another in series and / or in parallel. [0003] Especially in the case of electrically operated vehicles (EV), hybrid electric vehicles (HEV) or plug-in hybrid electric vehicles (PHEV), the use of batteries comprising energy-rich and powerful lithium-ion batteries or lithium-polymer batteries A battery module of a battery, wherein the battery module preferably has approximately one hundred battery cells in order to be able to meet the increased expectations for driving performance. [0004] Due to the chemical conversion process, lithium-ion battery cells or lithium polymer battery cells heat u...
