Embodiment Construction

[0052] figure 1 An embodiment of a battery module 1 according to the invention is schematically shown in a sectional view from the side.

[0053] The battery module 1 includes at least one battery cell 2 which has a battery cell housing 3 .

[0054] In this case, the electrochemical components 4 of at least one battery cell 2 are accommodated in the battery cell housing 3—in the figure 1 cannot be identified in .

[0055] In this case, the electrochemical component 4 of the at least one battery cell 2 can comprise, for example, a cathode element, an anode element and a separator element.

[0056] Furthermore, the battery module 1 includes a battery module housing 5 . In this case, at least one battery cell 2 is accommodated in the battery module housing 5 .

[0057] Here, from figure 1It can be seen in the sectional view that a temperature-control fluid receptacle 6 is formed between the battery module housing 5 and the battery cell housing 3 of at least one battery cell ...

Abstract

A battery module comprises a battery cell having a battery cell housing and a battery module housing, wherein a coolant fluid intake is configured between the battery module housing and the battery cell housing, such that a direct and thermal contact is provided between the coolant fluid and the battery cell housing, the battery cell housing further comprises a gas venting opening, which is configured to discharge gas from the interior of the battery cell housing directly to a surrounding environment, the gas venting opening of the battery cell housing is isolated from the coolant fluid intakein a fluid-tight manner, and one lateral surface of the battery cell housing of the at least one battery cell , on which the gas venting opening is arranged, other than in the region of the gas venting opening , is essentially entirely enclosed by the coolant fluid intake.

Description

technical field [0001] The starting point of the invention is a battery module with a plurality of battery cells according to the preambles of the independent claims. Background technique [0002] It is known from the prior art that a battery module can be formed from a plurality of individual battery cells, which can be electrically conductively connected to one another in series and / or in parallel, so that the individual battery cells are connected together to form a battery module. [0003] Furthermore, such battery modules can be connected to form a battery or a battery system. [0004] Due to the large number of different vehicle installation spaces, variable module dimensions are preferred in order to be able to optimally utilize the available vehicle installation space. [0005] Lithium-ion battery cells or lithium-polymer battery cells heat up due to chemical conversion processes, in particular when energy is released (for example, during driving) or when energy is ...
