Embodiment Construction

[0033] 1 schematically shows a side view of a housing arrangement 10 according to the invention. The frame element 20 is shown here in a side view, the wall 30 of which forms an interior space 40 . A battery cell 1 and / or a battery module 1 composed of a plurality of battery cells 1 can be arranged in the interior space 40 . This is shown by dashed lines. Furthermore, it can be seen that the frame element 20 of the housing arrangement 10 has a width direction or width 41 , in particular substantially perpendicular to the direction of flow of the fluid 5 in the region of the ventilation opening 50 . In contrast, the height 42 runs perpendicular to the width 41 and essentially parallel to the direction of flow in the region of the ventilation recess 50 . The flow directions of the incoming fluid 5 and the outgoing fluid 5 are schematically indicated here by arrows. Furthermore, the wall thickness 33 of the wall 30 is marked, which specifies in particular the distance between ...

Abstract

The invention relates to a housing device (10) for at least one battery cell (1), preferably a lithium battery cell (1) and / or a lithium pouch battery cell (1), wherein the housing device (10) Comprising at least one frame element (20), the frame element has a wall (30) and an inner cavity (40) formed by the wall (30) for accommodating the battery unit (1), wherein the wall (30) is provided with There are a plurality of ventilation openings (50), which have an alternate orientation such that the inflow of fluid (5) through the ventilation openings (50) takes place alternately.

Description

technical field [0001] The invention relates to a housing arrangement for a battery cell, preferably a lithium battery cell and / or a lithium pouch battery cell. Furthermore, the invention relates to a battery system, a method and a ventilation system. Background technique [0002] It is known from the prior art to realize battery cells, in particular lithium battery cells, for example in the form of so-called pouch cells (eg also pouch cells or coffee pod cells). In this case, the housing of the battery cell is generally not designed rigidly, but consists of a foil, for example made of aluminum. The housing and / or the battery cell thus have a certain flexibility and the battery cell thus has a wide range of application possibilities. [0003] Since the battery cells are usually only welded in the foil, the battery cells have insufficient mechanical stability for many applications. Due to the high power and energy density of lithium batteries, temperature increases can als...
