Description
Technical Field
The invention relates to a battery system having at least one battery cell, which is accommodated in a frame, and having a frame and at least one expansion region (Schwellbereich) between the frame and/or further battery cells, in which expansion region the at least one battery cell can be enlarged. The invention also relates to a method for producing a battery system and to a motor vehicle having at least one battery system according to the invention.
Background
In the battery system, individual battery cells are provided, which may change their volume, for example, during charging and discharging. The volume of the battery cell may also change during the service life (variaieren). In battery systems, the battery cells are usually arranged in a frame which receives a force of a volume change (aufnehmen). Especially in the case of solid battery systems, up to a 20% increase in volume of the individual battery cells may occur.
In mobile battery systems, as are used in particular in motor vehicles, a further requirement of the battery system is that the individual battery cells are particularly reliably fixed, so that the mechanical load on the individual cells is reduced.
Disclosure of Invention
A battery system is proposed, which has at least one battery cell and a frame in which the at least one battery cell is accommodated. According to the invention, the battery system has at least one expansion region between the frame and/or the further battery cells, in which expansion region the at least one battery cell can be enlarged. Furthermore, according to the invention, it is provided that a compressible expansion compensation material (schwellia gleichemical) is located in at least one expansion region on the at least one battery cell. In other words, in a battery system, a battery cell, in particular a solid battery cell, is held in a holding device (Halterung) in which one or more single cells can be accommodated. In order that the change in volume of the battery cells is not directly transmitted to the frame, an expansion region is provided so that the battery cells can also be accommodated in the frame without mechanical stress if the volume of at least one battery cell is increased. Here, the expansion region in the battery system is not empty, but filled with a compressible expansion compensation material. It can be provided here that the expansion compensation material contains at least one of the following: the material properties of the mass ensure compressibility. The arrangement of the compressible expansion compensation material in the expansion region offers the advantage that the battery cell is also reliably held in the frame in the following states: in this state, the volume of the battery cell is not increased. The battery pack system can be provided as an energy supply device, in particular for the movement of a motor vehicle. Another advantage is that mechanical stresses are absorbed (affangen) in the compressible expansion compensation material and are not transmitted to the frame in the following states: in this state, the battery cell has an increased volume. As a result, the frame can be produced accordingly more simply and/or more cost-effectively.
In battery systems according to the invention, it can be provided that the expansion compensation material is reversibly compressible, that the volume of the battery cell does not only increase forcibly during its service life, that is to say that the volume of the battery cell decreases again after expansion, depending on the ambient conditions, it can be achieved in battery systems that, on the basis of the compressible expansion compensation material, it can revert (zur ü ckkehren) into its original, uncompressed state.
In the context of the present invention, it can be provided in battery systems that the use of ethylene-propylene-diene rubber (EPDM) provides the advantage that the ethylene-propylene-diene rubber, on account of its saturated frame structure (Ger ü ststruktur), not only has a particularly high heat resistance but also a particularly high chemical resistance.
In other words, it can be provided that air bubbles (gasf ö rmige blast) are located in the expansion compensation material, wherein the air bubbles are surrounded by solid walls (fese W ä nde). this provides the advantage that the weight of the expansion compensation material is reduced compared to an expansion compensation material without a foam-like material.
According to the invention, it can also be provided in a battery system that the expansion compensation material has a Gel (Gel), in other words that the expansion compensation material has at least two components, wherein a solid component (fe komponene) forms a sponge-like network, the pores of which are filled with a fluid (ausf ü llen), wherein the two components penetrate completely through one another here (durchdringen), which provides the advantage that the expansion compensation material can be adapted well to its external surroundings, in particular to the frame and/or the battery cell, thus ensuring optimal contact.
In the battery system according to the invention, it can be provided that the expansion compensation material has a thermally conductive material. In particular during rapid charging or when high power is output by the battery cells, it can happen that the temperature of the battery cells increases strongly. By using a thermally conductive material, the advantage is achieved that heat can be output more quickly and that maintenance of the operating temperature can be ensured. It may be provided that the thermally conductive material in the expansion-compensating material is only provided between the battery cells, thereby establishing the thermal conduction of the battery cells to each other. This provides the advantage that all battery cells can be kept at similar temperatures, which simplifies the construction of the tempering system. As the heat-conducting material, a metal, in particular copper, can be provided, which has a particularly high heat-conducting capacity. Alternatively, a thermally conductive plastic can also be provided, which has a reduced weight compared to metal and enables simple production methods, in particular injection molding and coextrusion (koextrus).
According to a second aspect of the invention, a method for producing a battery system, in particular according to one of the preceding claims, is claimed, wherein at least one battery cell is inserted into a (einsetzen) frame, wherein an expansion region is provided between the frame and/or a further battery cell, in which expansion region the at least one battery cell can be enlarged, is introduced into the expansion region, wherein a compressible expansion compensation material is introduced into the expansion region, wherein it is furthermore provided that at least part of the expansion compensation material is physically foamed (physikasch gesch ä umt) before the introduction and/or that at least part of the expansion compensation material is foamed only when at least one battery cell is in the frame.
Furthermore, in the method, provision may be made for at least part of the expansion compensation material to be foamed by a chemical process. In this case, for particularly rapid foaming, provision can be made for a foaming agent (treibmitel) to be introduced into the expansion compensation material in order to start and/or control the foaming process. Alternatively, it can also be provided that a chemical reaction which induces (induzieren) foaming takes place with the reactant (Edukt) from the atmosphere which surrounds the expansion compensation material. This provides the advantage that particularly low-cost foaming can be achieved.
Advantageously, in the method according to the invention, provision can be made for the expansion compensation material to be produced by coextrusion and/or by injection molding. The production by coextrusion offers the advantage that complex forms of the expansion-compensating material with a plurality of materials in the form of coils (im Strang) can also be produced particularly quickly and at low cost. The production of the expansion compensation material by means of injection molding offers the advantage that particularly large numbers of pieces can be produced at low cost, wherein the injection molding method allows a particularly large choice of the shape and surface structure of the expansion compensation material.
Furthermore, it can be provided that the compressible expansion compensation material has a composite film (Verbundfolie) and/or a plate, which is produced by means of coextrusion and/or injection molding. In this case, it can be provided that the thermally conductive film is first inserted into the tool during injection molding and then post-molded with foamed plastic (hinterspritzen). This provides the advantage of combining the thermal conductive properties of the film for tempering the battery cells with the restoring force of the foam for reliably holding the battery cells. With the same advantages, instead of two-stage (zweistrufig) injection molding, a 2-component injection molding process (2-komponen-Spritzgie β verfahren) can also be used, wherein additionally particularly rapid production is possible. It can furthermore be provided that the compressible expansion compensation material is produced by means of co-extrusion as an at least two-layer plastic film, wherein one layer comprises foamable plastic and the other layer comprises thermally conductive plastic. The method also offers the advantage of combining the temperature control of the battery cells by the thermally conductive film with a reliable retention by the foamable plastic.
According to a third aspect of the invention, a motor vehicle is claimed, having at least one battery system according to any one of the preceding claims. For the motor vehicle according to the third aspect of the invention, the same advantages as have been described in detail with respect to the battery pack system according to the first aspect of the invention apply.
Further features and details of the invention emerge from the dependent claims, the description and the drawings. The features and details which have been described in connection with the method according to the invention are also obviously applicable in connection with the battery system according to the invention, the motor vehicle and/or the fuel cell according to the invention and vice versa, respectively, so that the disclosure with respect to the individual inventive aspects is always or can be mutually referenced.
The method steps may be performed at least partially (tlw.) simultaneously or temporally successively, the order of the method steps not being limited to the illustrated order, so that the individual steps may be performed in a different order.

Detailed Description
Fig. 1 shows a battery cell 101, which has an original shape in the left part of the figure. The same battery cell 101 is shown in the right part of the figure, wherein the volume of the battery cell 101 has increased. The space in which the battery cells have been enlarged is referred to as an expansion region 102 and is shown in shadow in fig. 1. Depending on the configuration of the battery cell 101, the expansion region may be limited on each side of the battery cell 101 or, as shown in the figures, on two preferred faces. In the case of pouch cells, which are usually packaged in a film, the expansion region 102 is located predominantly in the planar region of the film, but not in the region of the edge seam, wherein the film is closed by the welded edge seam. The inhomogeneous expansion region 102 can be realized, for example, in that the surface on which the expansion is to occur is particularly large or different materials are used for different sides, wherein on the side which is to be provided with the expansion region 102 there is a more flexible material than on the side on which the expansion region 102 is not provided. This provides the advantage that the enlargement of the battery cell 101 is only performed in a certain direction, so that a corresponding expansion compensation can be performed.
In fig. 2, an embodiment of a battery system 100 according to the invention is shown, which shows a battery cell 101 and a frame 103 in which the battery cell 101 is accommodated. In fig. 2, expansion regions 102 are not shown, which expansion regions 102 are between the frame and the battery cells 101 and between the individual battery cells 101, into which expansion regions the battery cells 101 can be enlarged. In fig. 2, at least one compressible expansion compensation material 104 is shown arranged on each battery cell 101. The expansion compensation material is arranged here such that it fills at least the expansion region 102 of the battery cell 101. Here, it can also be provided that a compressible expansion compensation material is arranged between the battery cells 101 and the frame 103. This provides the advantage that particularly little force is transmitted to the frame 103 in the event of swelling of the battery cells 101. Furthermore, it can be provided that different expansion compensation materials 104 are used in the battery system 100. It can be provided that the compressible expansion compensation material 104 arranged on the frame has a heat insulating material and that the compressible expansion compensation material 104 between the battery cells 101 has a heat conducting material. This provides the advantage of homogenizing the temperatures of the battery cells 101 with respect to each other (homogenieseren), while shielding the battery cells 101 as a whole from the temperature influence of the surroundings. It can be provided that a part of the frame 103 is designed as a temperature control system. This provides the advantage that the battery cell 101 can be kept at a constant temperature which is particularly effective for operation.
The use of elastomers offers the advantage that elastomers have a particularly high restoring capacity (R ü ckstellverm ö gen) so that the battery cell 101 can be held particularly well in its normal state, as shown in FIG. 2, and furthermore, elastomers have particularly good temperature insulation, in particular with respect to metals.
It can be provided that the expansion compensation material 104 is reversibly compressible, so that the battery cell 101 is then also securely fixed in the frame 103 when the battery cell 101 returns from the expanded state, as is shown in particular on the right in fig. 1, to the normal state, as is shown in particular on the left in fig. 1. This provides the advantage that the mechanical load on the battery cell 101 caused by the shock in the normal state is reduced. Thereby, the service life of the battery cell 101 is also extended. In mobile applications of the battery system 100, in particular in motor vehicles, further advantages result: only a small noise generation occurs.
Fig. 3 shows a section of the battery system 100 according to the invention (Ausschnitt). Between the two battery cells 101 there is arranged a swelling compensation material 104. In fig. 3, the expansion-compensating material 104 is shown with a foam-like material 105. The foam-like material 105 provides the advantage that it has a smaller weight compared to the expansion-compensating material 104 without foam-like material.
Furthermore, it can be provided that the expansion compensation material has a gel. The manufacture of the battery system 100 is schematically illustrated in fig. 4. The expansion compensation material 104 is located between two battery cells 101 arranged in a frame 103. It may be provided that a gel may be arranged in the free space between the battery cell 101 and the expansion-compensating material 104 and/or the further battery cell 101 and/or the frame 103. This provides the advantage that particularly inaccessible areas can be filled with the expansion-compensating material 104 in order to ensure a reliable retention of the battery cell 101.
Furthermore, it can be provided that the expansion compensation material has a thermally conductive material. It can be provided here that the expansion compensation material 104 then has a thermally conductive material when the expansion compensation material 104 is arranged between two battery cells 101 or between a battery cell 101 and a temperature control device. This provides the advantage that the temperature distribution in the battery cell 101 is homogenized and a particularly good tempering is achieved.
In fig. 4 and 5, it is shown that at least a part of the expansion compensation material 104 is foamed only when at least one battery cell 101 is in the frame 103. In the illustrated embodiment of fig. 4, at least two battery cells 101 are in the frame 103 of the battery system 100. Furthermore, a swelling compensation material 104 has been arranged on the battery cell 101. In this case, it can be provided that in a subsequent step at least part of the expansion compensation material 104 is foamed, so that the free space between the expansion compensation material 104 and the further battery cells 101 is closed (schliessen), as shown in fig. 5. In this case, it can be provided that at least part of the expansion compensation material 104 is foamed by a chemical process. This offers the advantage that also regions which are difficult to access, in particular regions in which physical foaming is not possible, are reached. Alternatively, it can also be provided that at least part of the expansion compensation material is physically foamed during production.
In addition, it can be provided that at least one battery pack system 100 is arranged in a motor vehicle 200 (see fig. 6) in order to be used as an energy carrier (energy ä ger), in particular for a drive device, the battery pack system according to the invention provides the advantage that it is held particularly securely in the frame 103 and also generates particularly little noise when subjected to vibrations.
The foregoing description of the embodiments merely describes the invention in the context of examples. It is clear that the individual features of the embodiments can be freely combined with one another as far as technically meaningful without departing from the scope of the invention.
