Definitions
- the present invention relates to a housing for a battery cell, a
- Battery cell Battery cell, a battery module and a motor vehicle.
- Housings for lithium-ion cells are usually made of deep-drawn
- Such cases are called hardcase cases.
- Such a metallic housing is electrically conductive.
- Electrode is placed on the housing.
- the housing has to be electrically insulated for itself. Only then is it possible to group the cells connected in series in a battery module cell by cell without short circuits.
- the insulation of the housing of the cell takes place via an electrically insulating surface, for example by packaging the cell with self-adhesive polyester film.
- Insulation fault monitoring issues an error message.
- a housing for a battery cell preferably a lithium-ion battery cell
- the housing according to the invention of a metallic inner part and the inner part partially surrounding thermoformed outer shell made of plastic, which is electrically insulating.
- the outer shell For the design of the outer shell a variety of options are given, which ultimately is crucial that short circuits are reliably avoided, the outer shell must be provided in extreme cases only at the touching points of the battery cells including a surcharge for the creepage distances.
- Embodiments described below relate to housing for prismatic battery cells or for battery cells with a prismatic inner part, which of course are also applicable in a modified form for other forms of battery cells.
- the outer shell surrounds the metallic inner part of the housing on five sides, wherein preferably the side of the metallic inner part, which carries the terminals of the battery cell, is not covered by the outer shell.
- the outer shell therefore also has a prismatic shape or has a prismatic body, with one side being open.
- the outer shell covers the inner part of the housing only on three sides, so that it has a U-shaped cross-section.
- each battery cell is a separate one
- Outer shell designed such that at least two prismatic, open to one side body or shells are given, each of which is like the embodiment described above.
- the least two prismatic, open to one side body or shells are given, each of which is like the embodiment described above.
- prismatic bodies are connected to each other via a web or along an edge of the open side, thereby forming a common outer shell for at least two battery cells.
- the outer shell or the respective prismatic body to cover the inner part of the housing only on three sides, so that it in each case has a U-shaped cross section.
- the battery cells can be arranged in a row or else in at least two parallel rows.
- the connecting web (s) project beyond the surface formed by the open sides of the outer shell, thus creating a kind of "expansion crease" with which the distance between the individual prismatic bodies of the outer shell is variable
- the outer shell as in the embodiment described above, is designed such that at least two prismatic, open to one side body are given, which are connected to each other via a web or along an edge of the open side.
- the web is dimensioned in this embodiment such that its surface corresponds to the open side of a prismatic body.
- the web has two passage openings for the passage of the terminals of battery cells.
- a part of the battery cells is introduced into the open on one side prismatic body of the outer shell and the other part is positioned from the opposite side in the region or below the web.
- the respective prismatic body can also cover the inner part of the housing only on three sides.
- the battery cells may be arranged depending on the configuration of the common outer shell in a row or in at least two parallel rows.
- thermoformed outer shell of the housing consists of a
- thermoplastic Suitable plastics or plastic films or boards are known in the art, such as polyolefins, polyesters and the like.
- fiber-reinforced films possible to advantageously increase the mechanical stability of the outer shell again.
- the outer shell of the housing according to the invention advantageously has a higher mechanical strength and elongation at break and a higher dielectric strength compared to other solutions for the isolation of housings for battery cells, such as applied by dipping or painting materials or heat shrink tubing, due to the experienced in the production stretching on.
- the outer shell of the housing allows cost-effective isolation of battery cells through the use of tested, technically proven
- the outer shells for the housing according to the invention advantageously have no weld lines or overlapping splices, which may be the cause of defects in the insulation.
- the films used can also be easily checked for errors.
- thermoforming The methods used for the production of thermoforming or
- Stretch forming are familiar to the person skilled in the art. This is an automated, production-ready and process-reliable processing or
- Leave the film lead can be avoided.
- the outer shells can be manufactured with the help of a simple tool and are also suitable for the safe transport of the battery cells.
- the battery cells can be used directly as a positive mold.
- a battery cell module with at least two battery cells and a
- Motor vehicle in particular an electric motor driven motor vehicle, provided, which has at least one inventive battery cell module, which is connected to a drive system of the motor vehicle.

- Figure 4 is a perspective view of an outer shell for a
- the outer shell 10 is shown for receiving a metallic inner part of a housing for a battery cell.
- This outer shell 10 has a prismatic body 1 1 with five closed sides and an open side 12, via which the inner part of the housing, not shown, is introduced.
- the outer shell 10 shown in Figure 2 is provided for receiving two inner parts of housings on the open side 12.
- a web 13 is provided between the two prismatic bodies 1 1, which extends from an open side 12 of a prismatic body 1 1 to the next open side 12 of the other prismatic body 1 1.
- the webs 13 have the same area as the open sides 12 and two through holes 14 for the passage of terminals of the battery cells, not shown here, so that below the webs 13 two further internal parts can be arranged.
- the outer shell 10 shows a series of prismatic bodies 1 1, which are each connected to a web 13, but here extends beyond the plane formed by the open side 12 and a kind
- the outer shell 10 of Figure 4 corresponds substantially to the outer shell 10 of Figure 3, except here are two other lateral surfaces 15 and 16 of the prismatic body 1 1 also designed open, so that an inner part in the respective prismatic body 1 1 is enclosed in a U-shape ,
