In order to improve the use of batteries, in particular so-called medium-temperature batteries, in everyday applications, rapid operational preparation of the batteries is required.

In this case, the rapid operating preparation should be present both when starting an Electric Vehicle (EV) having such a battery pack and when charging the EV.

After a long parking time, both when starting the electric vehicle and when charging the electric vehicle, the battery cell heating process should preferably be carried out as efficiently as the cooling process, for example, during a travel with a comparatively high load on the battery pack and during a rapid charging process after such a travel with a comparatively high load.

Therefore, it is possible to provide a structure of a battery module that enables relatively rapid and long-term operational preparation of the plurality of battery cells.

To this end, a battery module having a plurality of battery cells is provided.

The battery module further includes a plurality of receiving members. The plurality of receiving elements are arranged adjacent to one another in the longitudinal direction of the battery module.

Furthermore, at least one battery cell is accommodated in the respective accommodating element.

In addition, the battery module also has a first temperature adjustment element configured to heat the battery cells, and the battery module also has a second temperature adjustment element configured to cool the battery cells.

In this case, the first receiving element is connected in a heat-conducting manner only to the first temperature control element, and the second receiving element is connected in a heat-conducting manner only to the second temperature control element.

According to the invention, the first receiving elements and the second receiving elements are arranged alternately in the longitudinal direction of the battery module.

Advantageous embodiments and improvements of the device specified in the independent claims are possible by the measures mentioned in the dependent claims.

In this case, adjacent first receiving elements and second receiving elements are advantageously each connected to one another in a form-fitting manner.

Preferably, the form-fitting connection is configured here as a connection in a clamping configuration. For this purpose, the respective first receiving element can, for example, form a bore, while the respective second receiving element can have an elastically deformable element, such as a snap-in element, a butt-joint element or a hook-in element.

In this case, the elastically deformable element of the respective second receiving element can engage in the bore of the respective first receiving element for the purpose of connecting in the clamping configuration.

This construction offers, inter alia, the following advantages: the first receiving element can be connected to the second receiving element in a simple manner, so that a simple installation of the battery module is possible.

It is thus also possible: the battery module is protrudingly stretchable, which means in other words: the battery module can have any number of first receiving elements and second receiving elements, as a result of which the battery module can be lengthened in particular as desired.

According to a preferred embodiment of the invention, the receiving elements, i.e. the first receiving element and the second receiving element, each comprise a first housing wall, a second first housing wall and a second housing wall, which together form a receiving space for the respective receiving element.

At least one battery cell is accommodated in the accommodation space.

In this case, the second housing wall is preferably connected, in particular thermally conductive, to the first housing wall and to the second first housing wall, in particular thermally conductive.

Furthermore, the second housing wall is preferably arranged between the first housing wall and the second first housing wall.

Furthermore, the first housing wall and the second first housing wall are preferably arranged parallel to each other.

The respective receiving element here has, in particular, a C-shaped configuration.

In addition, the first housing wall is connected in a thermally conductive manner to the first temperature control element, or the second first housing wall is connected in a thermally conductive manner to the second temperature control element.

It should be noted here that: the receiving element is a first receiving element if the first housing wall is connected in a thermally conductive manner to the first temperature control element.

It should also be noted here that: the receiving element is a second receiving element if the second first housing wall is connected in a thermally conductive manner to the second temperature control element.

This configuration offers the advantage of a simple construction of the battery module, wherein the first temperature control element and the second temperature control element can be connected in a simple manner in a thermally conductive manner to the battery cells.

The at least one battery cell is expediently connected in a thermally conductive manner to at least the second housing wall.

Furthermore, the at least one battery cell can also be connected in a heat-conducting manner to a first housing wall, if the receiving element is a first receiving element, or to a second first housing wall, if the receiving element is a second receiving element. It is thereby possible to: the temperature control, i.e. the heating or cooling, of the large area of the at least one battery cell is designed, wherein the at least one battery cell can be supplied with heat or dissipated of heat not only via the second housing wall but also via the first housing wall or the second housing wall.

According to a particularly preferred embodiment of the invention, two battery cells are accommodated in a respective accommodating element. This embodiment provides the following advantages: it is possible to provide a battery module in which all the battery cells can be reliably temperature-regulated.

In this case, a first battery cell of the two battery cells is arranged, for example, adjacent to the second housing wall and is in particular connected in a thermally conductive manner to the second housing wall. Furthermore, a second battery cell of the two battery cells may be arranged adjacent to the first battery cell, for example, on the side of the first battery cell opposite the second housing wall, so that in other words the first battery cell is arranged between the second battery cell and the second housing wall. In this case, the first battery cell can be tempered by the second housing wall of the respective receiving element, while the second battery cell can be tempered by the second housing wall of the receiving element arranged adjacent to the respective receiving element, so that, in other words, the second housing wall can always temper two battery cells arranged in different receiving elements.

According to an advantageous aspect of the invention, the first receiving element is arranged in each case in a thermally insulated manner from the second temperature control element and/or the second receiving element is arranged in each case in a thermally insulated manner from the first temperature control element. It is thereby possible to: the heating of the plurality of battery cells may be accomplished as independently as possible from the cooling of the plurality of battery cells, and conversely, the cooling of the plurality of battery cells may be accomplished as independently as possible from the heating of the plurality of battery cells.

Here, for example, it is possible: the first receiving element is arranged at a distance from the second temperature control element, and the second receiving element is arranged at a distance from the first temperature control element at a further distance.

Here, for example, it is also possible: between the first receiving element and the second temperature control element, in each case one heat shield is arranged, and between the second receiving element and the first temperature control element, in each case one further heat shield is arranged.

Preferably, the receiving elements are made of a metallic material, such as aluminum, so that a sufficient heat-conducting capacity can be formed. Thus, the battery module, which is relatively easy to construct, can be constructed to have good heat conductivity.

Overall, with the battery module according to the invention it is possible to: the individual battery cells of the plurality of battery cells are tempered relatively quickly, i.e. not only cooled relatively quickly but also heated relatively quickly.

As a result, a rapid and permanent operational preparation of the battery module as a whole can be achieved.

Preferably, the battery cells of the battery module are each constructed as a medium-temperature battery cell. The medium-temperature battery cell has a preferred temperature range from 50 ℃ to 90 ℃, and in particular a preferred temperature range from 70 ℃ to 90 ℃.

Within this temperature range, the medium temperature battery cells achieve optimal power.

With the battery module according to the invention it is possible to: the battery cells configured as medium-temperature battery cells are operated within this preferred temperature range.

The invention therefore also relates to the use of a battery module according to the invention, in which the battery cells are designed as medium-temperature battery cells and are operated in a temperature range from 50 ℃ to 90 ℃ and preferably from 70 ℃ to 90 ℃.

Drawings

Embodiments of the invention are illustrated in the drawings and are further described in the following description.

Wherein:

fig. 1 schematically shows an embodiment of a battery module according to the invention with a plurality of battery cells in a side view; while

Fig. 2 schematically shows an embodiment of the battery module according to the invention in a top view.

Detailed Description

Fig. 1 shows a schematic side view of an embodiment of a battery module 1 according to the invention with a plurality of battery cells 2. The battery cells are in particular designed as medium-temperature battery cells 20, which have a preferred temperature range from 50 ℃ to 90 ℃.

The battery module 1 further comprises a plurality of receiving elements 3. The receiving elements 3 are arranged adjacent to one another in the longitudinal direction 4 of the battery module 1.

Furthermore, at least one battery cell 2 is accommodated in the receiving element 3 in each case, wherein fig. 1 shows an embodiment of a battery module 1 in which two battery cells 2 are accommodated in the receiving element 3 in each case.

In particular, a first battery cell 21 and a second battery cell 22 are each accommodated in the respective accommodating element 3. A total of two battery cells 2, 21, 22 are therefore accommodated in the respective accommodating element 3.

The receiving element 3, 31, 32 is preferably made of a metallic material, such as preferably aluminum.

The battery module 1 here also comprises a first temperature control element 5, which is designed to heat the battery cells 2.

The first temperature control element 5 can be designed as a heating element 50, such as a heating plate, for example.

The battery module 1 here also comprises a second temperature control element 6, which is designed to cool the battery cells 2.

The second temperature control element 6 can be designed as a cooling element 60, such as a cooling plate, for example.

Here, the battery module 1 has a first receiving member 31 and a second receiving member 32, respectively.

In this case, the first receiving elements 31 are only in heat-conducting connection with the first temperature control elements 5.

In this case, the second receiving elements 32 are only in each case connected in a thermally conductive manner to the second temperature control element 6.

To this end, it is possible, for example: in order to form a thermally conductive connection, a first thermally conductive connecting element 131, which may be formed, for example, as a thermally conductive adhesive material or as a thermally conductive adhesive layer, is arranged between the first receiving element 31 and the first temperature control element 5.

For this purpose, it is also possible, for example: in order to form a thermally conductive connection, a second thermally conductive connecting element 132, which may be formed, for example, as a thermally conductive adhesive or as a thermally conductive adhesive layer, is arranged between the second receiving element 32 and the second temperature control element 6. In this regard, it should be noted here that: however, it is of course also possible to directly form the heat-conducting connections just described, so that the first receiving elements 31 are in each case directly heat-conducting connection with the first temperature control element 5, while the second receiving elements 32 are in each case directly heat-conducting connection with the second temperature control element 6.

In this case, the first receiving elements 31 are each thermally insulated from the second temperature control element 6, while the second receiving elements 32 are each thermally insulated from the first temperature control element 5.

For this purpose, as shown in fig. 1, the first receiving element 31 can be arranged, for example, at a distance from the second temperature control element 6 by a first distance 91, while the second receiving element 32 can be arranged at a distance from the first temperature control element 5 by a second distance 92.

Furthermore, but also conceivable are: for example, instead of the spacing caused by the spacings 91, 92, a heat shield can also be arranged, which is not shown in fig. 1, but which can of course also be arranged in addition to the spacing caused by the spacings 91, 92.

As can be seen from fig. 1, the first receiving elements 31 and the second receiving elements 32 are arranged alternately in the longitudinal direction 4 of the battery module 1, such that, for example, in the longitudinal direction 4 of the battery module 1, the first receiving elements 31 are followed by the second receiving elements 32, and, for example, in the longitudinal direction 4 of the battery module 1, the second receiving elements 32 are followed by the first receiving elements 31.

Here, fig. 1 shows: the receiving elements 3, 31, 32 comprise a first housing wall 711, a second first housing wall 721 and a second housing wall 720, respectively.

The housing walls 711, 721, 720 mentioned immediately above together form a receiving space 8 of the respective receiving element 3, 31, 32, in which at least one battery cell 2 or a first battery cell 21 and a second battery cell 22 are accommodated.

In this case, the second housing wall 720 is arranged between the first housing wall 711 and the second first housing wall 721 and is connected to these in each case and preferably also in a thermally conductive manner.

In this case, the first housing wall 711 is connected to the first temperature control element 5 in a thermally conductive manner if the respective receiving element 3 is the first receiving element 31, and the second first housing wall 721 is connected to the second temperature control element 6 in a thermally conductive manner if the respective receiving element 3 is the second receiving element 32.

The receiving elements 3 are in particular each designed in the following manner: as can be seen from fig. 1, a first housing wall 711 and a second housing wall 721 are arranged parallel to and spaced apart from each other. Furthermore, the second housing wall 720 is arranged at right angles to the first housing wall 711 and the second first housing wall 721, respectively, and is also connected to them, respectively, as already explained above.

Here, at least one battery cell 2 is arranged between the first housing wall 711 and the second first housing wall 721, or the first battery cell 21 and the second battery cell 22 are arranged between the first housing wall 711 and the second first housing wall 721. In this case, the first battery cell 21 is arranged adjacent to the second housing wall 720 and in particular is arranged in a thermally conductive manner with respect to this second housing wall 720.

Here, the second battery cell 22 is arranged adjacent to the first battery cell 21, and is arranged on the side of the first battery cell 21 opposite the second housing wall 720.

Thus, in other words, the first battery cell 21 is disposed between the second battery cell 22 and the second housing wall 720. In this case, the second battery cell 22 is also arranged next to the second housing wall 720 of the next adjacent receiving element 3 and is, for example, also connected in a thermally conductive manner to this next adjacent receiving element. For example, the second battery cell 22 of the first receiving member 31 is disposed adjacent to the second housing wall 720 of the second receiving member 32.

Furthermore, it is also possible: first battery cell 21 and second battery cell 22 are arranged at a distance from one another in order to compensate for a possible volume expansion of battery cell 2, wherein it is of course also possible to arrange a compensation element constructed from an elastic material between first battery cell 21 and second battery cell 22, which compensation element can compensate for this volume expansion.

Here, it is preferable that at least one battery cell 2 is thermally conductively connected to the second housing wall 720, or the first battery cell 21 is thermally conductively connected to the second housing wall 720.

With the battery module 1 according to the invention shown in fig. 1, it is possible to: the temperature of the battery cell 2 is reliably adjusted.

Fig. 2 shows a schematic top view of an embodiment of a battery module 1 according to the invention.

In this case, the second temperature control element 6 is omitted, so that the second first housing wall 721 of the respective receiving element 3 is visible in each case.

Here it can be seen that: adjacent first receiving elements 31 and second receiving elements 32 can each be connected to one another in a form-fitting manner.

For this purpose, the respective receiving element 3 can have, for example, not only the bore 10 but also an abutment element 11 or a hooking element 12, the bore 10 and the abutment element 11 or the hooking element 12 being at least partially elastically deformable. In this case, the receiving element 3, for example the abutment element 11 or the hooking element 12 of the first receiving element 31, can now engage into the opening 10 of the adjacent receiving element 3, for example the second receiving element 32, so that a form-fitting connection of the clamping arrangement can be formed.

It is thereby possible to: the battery module is arbitrarily lengthened and thus expanded and contracted.
