Embodiment Construction

[0032] figure 1 The receiving structure 10 for the battery cell 12 is shown in an exploded perspective view. In the case shown here, the battery cells 12 are circular battery cells. However, the following explanations also apply to battery cells of different shapes, for example in the form of prismatic cells, pouch cells, etc. In particular, the battery unit 12 may be a battery unit of a high-voltage battery for an electric vehicle.

[0033] The receiving structure 10 comprises a battery cell holder 14 made of foam material having a corresponding recess 16 for receiving and fixing the corresponding battery cell 12 . The battery cell holder 14 is shaped such that when a battery cell 12 is arranged as intended in the recess 16 , at least one area is freed for the respective battery cell 12 so that a non-conductive cooling medium can flow around the respective area. In the case shown here, the battery cell holder 14 is used to accommodate the battery cells 12 which are designe...

Abstract

The invention relates to a receiving structure (10) for battery cells (12), more particularly of a high-voltage battery for a motor vehicle, comprising a cell holder (14) produced from a foam material (14) and having recesses (16) for receiving and securing the respective battery cells (12), the cell holder (14) being shaped in such a manner that when the battery cells (12) are positioned in the recesses (16) as intended, at least one region at the battery cells (12) is left uncovered such that an electrically non-conductive cooling medium can flow around this region. The invention further relates to a battery (24), more particularly a high-voltage battery for a motor vehicle having at least one receiving structure (10) of this kind, and to a method for producing a receiving structure (10) for battery cells (12).

Description

technical field [0001] The invention relates to a receiving structure for a battery cell, in particular for a battery cell of a high-voltage battery of a motor vehicle. The invention also relates to a battery, in particular a high-voltage battery of a motor vehicle, having at least one such receptacle, and a method for producing a receptacle for a battery cell. Background technique [0002] In electric vehicles, the energy to drive the vehicle is usually taken from the battery. Electric motors used to drive motor vehicles consume large amounts of electrical energy, especially when the motor vehicle is accelerating. When extracting energy from the battery, the sum of all resistances, eg due to internal resistance within the battery cell, due to contact resistance, etc., depending on the current flowing, results in a power loss which is converted into heat. Power loss heats the battery or battery cell, so if this thermal energy is not dissipated, the battery or battery cell ...
