Embodiment Construction

[0035] figure 1 A distribution device 10 for distributing caulk 12 is shown. In the embodiment shown here, the distribution device 10 has an injection nozzle 14 and a vacuum generating device 16 . Furthermore, the vacuum generating device 16 shown here has a cover 18 and a pump 20 arranged on the cover.

[0036] exist figure 1 In the illustrated embodiment, the injection nozzle 14 is connected to the battery housing 24 at a predetermined injection site 22 . A battery module 26 including a plurality of battery cells 28 is arranged inside the battery housing 24 . exist figure 1 In , a cavity 30 is shown between the battery housing 24 and the battery module 26 . With the aid of arrow 31 at figure 1 It is explained how the caulk 12 is sucked into the cavity 30 between the battery housing 24 and the battery module 26 by the negative pressure generated by the negative pressure generating device 16 and distributed in the cavity. exist figure 1 In the exemplary embodiment show...

Abstract

The invention relates to a distribution device (10) for distributing an interstitial material (12) in a cavity (30) between at least one outer side of at least one battery module (26) of a battery (40) and an inner side of a battery housing (24) at least partially surrounding the respective battery module (26) and facing the at least one outer side of the respective battery module (26) of the battery (40). The distribution device (10) has at least one injection nozzle (14) which is designed to inject the interstitial material (12) into the cavity (30), and a negative pressure generating device(16), wherein the negative pressure generating device (16) is designed to establish the negative pressure in the interior of the closed battery housing (24) comprising the cavity (30), and the injected interstitial material (12) is drawn into the cavity (30) by means of the negative pressure and is distributed in the cavity.

Description

technical field [0001] The invention relates to a distribution device for connecting at least one outer side of at least one battery module of a battery with at least one outer side of a battery housing of the battery which at least partially surrounds the corresponding battery module and facing the corresponding battery module Gap filler is distributed in the cavity between the inner sides. The invention also relates to a method for distributing a caulk in such a cavity. Background technique [0002] When installing the battery, if at least one battery module is inserted into a battery housing which at least partially surrounds the battery module, then, for example, due to installation, at least one outer side of the at least one battery module and at least one A cavity is formed between the inner sides of the battery housing on one outer side. Since the presence of such cavities can have a negative effect on the operation of the battery, there are various measures for fi...
