Technical area

The present invention relates to a battery assembly, for example a vehicle battery arrangement.

State of the art

There are battery arrangements are known which receive a plurality of battery cells, wherein a plurality of the battery cells are each combined in or on a module frame as a battery module. Such battery arrangements find application both in primary batteries, thus non-rechargeable batteries, as well as secondary batteries, thus rechargeable batteries.

It is known to arrange the battery cells vertically oriented on heating and / or cooling plates in battery arrangements. In order to achieve a good heat transfer, between the battery cells and / or the module frame and the heating and / or cooling plate, a component for heat conduction and electrical insulation, such as a thermal grease, introduced and the module frame firmly screwed to the heating and / or cooling plate , In general, the module frame is screwed from above in the pressing direction on the heating and / or cooling plate.

In order to provide battery assemblies with the above-mentioned construction, in which the battery cells, however, are arranged horizontally mounted on vertically oriented cooling plates, a mounting space for the lateral introduction of tools is necessary to screw the battery cells or the module frame with the heating and / or cooling plates. As a result, due to installation increases the required space of the battery assembly, which thus constructed battery assemblies have a lower volumetric energy density.

To take account of the aforementioned disadvantages, is approximately from the WO2014 / 184419 A1 a system for packaging and thermal management of battery cells in a battery module, in which battery cells are held in laterally arranged profiles. The profiles have cooling channels for cooling the battery cells.

From the DE 10 2014 019 074 A1 a cell block for a motor vehicle battery is known in which horizontally arranged battery cells are screwed to a laterally arranged therefrom, designed as a heating or cooling plate temperature control device.

From the EP 2 515 361 A1 is to be taken from a battery unit, wherein battery cells are held firmly in a frame, wherein for securing the battery cells tensioning rods and cell holders are braced in the direction of the main orientation of the battery cells acting together.

The US Pat. No. 9,070,958 B2 shows a generic battery assembly in which a clamping device comprising a support and a hold-down braces the module frame together. The temperature control plate is arranged below the modules.

Presentation of the invention

Starting from the known prior art, it is an object of the present invention to provide an improved battery assembly, in particular an improved vehicle battery assembly.

The object is achieved by a battery arrangement with the features of claim 1. Advantageous developments emerge from the dependent claims of the description and the accompanying figures.

Accordingly, a battery arrangement, in particular a vehicle battery arrangement, is proposed which comprises a module frame clamped between a support and a support arranged opposite the support for receiving a plurality of battery cells, and a tempering device having a temperature control surface for tempering the battery cells. According to the invention, the support, the hold-down device and the module frame are designed in such a way that a clamping force exerted on the module frame by the support and downholder parallel to the temperature control surface biases the module frame onto the temperature control surface.

Characterized in that the support, the hold-down and the module frame are formed such that a parallel to the Temperierungsfläche by support and hold down on the module frame clamping force biasing the module frame on the Temperierungsfläche, can easily moving or pressing the module frame and / or the battery cells accommodated therein are reached in the direction of the temperature control surface and / or the battery cells accommodated therein are reached in the direction of the temperature control surface when the hold-down device is tightened. The assembly and the pressing on the Temperierungsfläche is achieved by a simple tightening the hold. Consequently, a secure application of the module frame and / or the battery cells can be achieved at the Temperierungsfläche be so that an efficient heat transfer between Temperierungsvorrichtung and the module frame and / or the battery cells is possible.

Furthermore, this makes it possible to easily install the battery cells in the vertical direction. In other words, it is possible by the aforementioned embodiment of the battery assembly, the battery cells to orient horizontally and one above the other, thus in the vertical direction, to layer, the Temperierungsfläche is oriented vertically. Such a constructed battery assembly can be constructed very compact and so little space, for example, in a vehicle, which is to provide the battery assembly with electrical energy occupy.

According to a preferred embodiment, the module frame on the side facing the hold-down on an inclined first contact surface, which is in contact with a parallel thereto oriented counter surface of the blank holder, wherein the first contact surface is oriented away from the Temperierungsfläche.

In the present case, an "inclined surface" is understood to mean a surface which encloses an angle not equal to 90 ° with a plane in which the temperature control surface extends. Consequently, the normal of the "inclined surface" with the plane includes an angle greater than 0 ° and less than 90 °. A wedge is provided by a surface oriented away from the tempering surface, which wedge with increasing distance to the tempering surface.

Consequently, the first contact surface is oriented in such a way that the module frame and / or the battery cells are pressed by means of a clamping force generated by the support and hold-down on the module frame, which acts essentially parallel to the Temperierungsfläche or their plane by means of a contact force generated by the clamping force on the inclined contact surface be pressed in the direction of Temperierungsfläche. Accordingly, due to the inclined contact surface, a force acting on the module frame pressing force is generated, which acts in the direction of the Temperierungsfläche. The pressing force acting in the direction of the tempering surface causes the pressing of the module frame or the battery cells. Furthermore, the module frame can thereby be centered with respect to the Temperierungsfläche. The module frame slides with its contact surfaces on the mating surfaces of support and hold-down until it rests against the Temperierungsfläche.

According to a further preferred embodiment, the module frame on the side facing the support on an inclined second contact surface which is in contact with a parallel thereto oriented counter surface of the support, wherein the second contact surface is oriented away from the Temperierungsfläche. As a result, the effect described for the first inclined contact surface can be achieved analogously.

In order to additionally achieve a centering of the module frame with respect to the tempering device in relation to a direction parallel to the plane of the tempering surface in addition to the pressing of the module frame, according to a further preferred embodiment the module frame may have an inclined first contact surface on the side facing the blank holder. which is in contact with a mating surface of the blank holder oriented parallel thereto, and the module frame on the side facing the support may have a second contact surface inclined opposite to the first contact surface which is in contact with a mating surface of the support oriented parallel thereto, wherein the first and second contact surface facing away from the Temperierungsfläche oriented.

As a result, in each case a contact pressure force is generated at the first contact surface and at the second contact surface. Furthermore, a centering movement of the module frame takes place both on the underside and on the upper side of the module frame. Here, the first and the second contact surface are oriented such that the module frame and / or the battery cells by means of the clamping force generated by the bearing and hold-down on the module frame, which acts substantially parallel to the Temperierungsfläche or its plane, by means of the clamping force generated by the clamping force Direction of Temperierungsfläche be pressed. In other words, a force acting on the module frame pressing force is generated due to the inclined contact surfaces, which acts in the direction of the Temperierungsfläche. The pressing force acting in the direction of the tempering surface causes a pressing of the module frame or the battery cells. For centering, the module frame slides with its contact surfaces on the mating surfaces, until it rests against the Temperierungsfläche. Both at the bottom and at the top of the module frame thus takes place a centering movement. The module frame can thus be easily inserted for mounting the battery assembly.

According to a further preferred embodiment, the first contact surface and / or the second contact surface are formed integrally with the module frame. As a result, the battery assembly has only a small number of parts and therefore a particularly simple structure. Alternatively, that the first contact surface by means of a arranged on the module frame first wedge body and / or the second contact surface may be provided by means of a arranged on the module frame second wedge body. As a result, the aforementioned parts may have simple shapes or geometries and be correspondingly easy to manufacture or may be partially constructed as standard parts.

In order to further reduce the number of parts and / or to provide a stable structure, the counter surface of the blank holder may be integrally formed with the hold-down and / or the mating surface of the support may be integrally formed with the support. Alternatively, the mating surface of the blank holder can be provided by means of a hold-down wedge element associated with the hold-down element and / or the mating surface of the support can be provided by means of a hold-down wedge element associated with the support, which have a correspondingly simple shape to produce.

According to a further preferred embodiment, battery cells accommodated in the module frame are additionally pressed against one another in the direction of stratification of the battery cells by the clamping force generated by means of supports and hold-down means. This makes it possible to dispense with additional elements for centering and / or securing the battery cells. In other words, the battery cells are held in the module frame in an adhesive fit.

In order to further improve the heat transfer between the Temperierungsfläche and the module frame or the battery cells, between the Temperierungsfläche and the module frame and / or between the module frame and the battery cells, a thermally conductive component or layer, preferably a thermal paste or a Wärmeleitpad be arranged. The thermally conductive component preferably has electrically insulating properties. Thus, it can be ensured that a sufficiently good heat conduction between Temperierungsvorrichtung and battery cells achieved while an electrical insulation is provided therebetween, and so the reliability of the battery assembly is increased.

According to a further preferred embodiment, in each case a module frame is arranged on both sides of the tempering device, wherein the hold-down device has a counter surface on both sides relative to the tempering device and / or the support has a counter surface on both sides with respect to the tempering device, the counter surfaces being oriented in such a manner, that the module frames are pressed from both sides against a respective temperature control surface of the tempering device. As a result, the battery assembly can be particularly easily constructed with very few parts.

In order to further simplify the construction of the battery assembly, the support and the temperature control device may be integrally formed or the hold-down device and the tempering device may be integrally formed.

According to a particularly preferred further embodiment, a module counter frame and an abutment, comprising a further support and another hold-down, are arranged on the opposite side of the plurality of battery cells accommodated in the module frame, wherein the further support, the hold-down and the module counter frame are formed in that a clamping force exerted on the module counterframe parallel to the plane of the tempering surface by the additional support and the further hold-down device biases the module counterframe onto the temperature-control surface. As a result, an additional contact force is generated in the direction of the Temperierungsfläche. As a result, the battery assembly can be mounted very easily. The module frame, the module counter frame and then the battery cells can be easily inserted; a further positioning and / or attachment is not necessary, since this is already achieved by the clamping.

According to a further preferred embodiment, the module counterframe has an inclined first contact surface, which is in contact with a counter surface of the further hold-down oriented parallel thereto, and / or the module counterframe has an inclined second contact surface, which has a mating surface of the further support oriented parallel thereto is in contact, wherein the first contact surface and / or the second contact surface of the module counter frame are oriented away from the Temperierungsfläche, wherein the second contact surface is preferably oriented opposite to the first contact surface.

As a result, the battery cells can be kept very safe centered and stored. Analogous to the module frame, the first and the second contact surface of the module counter frame are oriented such that by means of the clamping force generated by the further support and the further hold-down on the module counter frame, which acts substantially parallel to the Temperierungsfläche, the battery cells by means of the contact force generated on the inclined contact surfaces in the direction of the module frame and the Temperierungsfläche be pressed. Furthermore, the module counter frame may be centered with respect to the temperature control surface. Both at the bottom and at the Top of the module counter frame is a centering movement in the direction of Temperierungsfläche. The assembly of the battery assembly is thus further simplified.

In order to be able to provide a particularly secure reception of the battery cells and to be able to preassemble module frames, module counterframes and battery cells as a preferably exchangeable module, according to a further preferred embodiment the module frame and the module counterframe form a module cage, wherein the module frame and the module counterframe are preferably connected via cross struts are.

According to a further preferred embodiment, the battery cells are stacked along a direction parallel to the orientation of the temperature control surface. Furthermore, the tempering surface can be arranged perpendicular to a preferably horizontally oriented base plate. As a result, the battery assembly can be made very compact and take up little space, for example, in a vehicle, which is to provide the battery assembly with electrical energy.

Detailed description of preferred embodiments

In the following, preferred embodiments will be described with reference to the figures. In this case, identical, similar or equivalent elements in the different figures are provided with identical reference numerals, and a repeated description of these elements is partially omitted in order to avoid redundancies.

In 1 is a schematic sectional view of a battery assembly 1 shown here in the form of a vehicle battery assembly, according to a first embodiment. Between a support 2 and one the support 2 arranged opposite hold-down 3 is a module frame 4 clamped. In the module frame 4 is a plurality of battery cells 5 arranged. Next to the module frame 4 is a tempering device 6 provided which a Temperierungsfläche 60 for tempering the battery cells 5 having.

The support 2 is on a base plate 9 the battery arrangement 1 arranged. The base plate 9 may be, for example, the bottom plate of a housing. From this extends the tempering device 6 with a longitudinal extent perpendicular to the base plate 9 , The temperature control surface 60 is present with its plane e , in which it extends, also perpendicular to the base plate 9 oriented.

The tempering device 6 is integral with the support 2 educated. Alternatively, however, the parts may also be provided separately and / or the tempering device 6 Can be integral with the hold down 3 be educated. In the present case is the hold-down 3 by means of a screw connection 34 to the tempering device 6 screwed.

The module frame 4 and the tempering device 6 are presently designed such that the hold-down 3 on impact or on block with the tempering device 6 is screwed. So the downholder is 3 in the assembled state in the direction parallel to the plane e completely to the tempering device 6 screwed so that a tightening torque of the screw connection 34 has no influence on the contact force with which the module frame 4 to the tempering device 6 or the Temperierungsfläche 60 is pressed. A distance, which with completely screwed down holder 3 between supports 2 and hold down 3 parallel to the plane e is present, is dimensioned so that the module frame 4 is clamped with a clamping force corresponding to the distance and, as described in detail below, with a contact force predetermined thereby in the direction of the temperature control surface 60 is pressed. In other words with clamp down on block 3 still a marginal play between the module frame 4 and the tempering device 6 available.

Alternatively, the module frame 4 with its extension parallel to the plane e be formed longer than the distance, which with completely screwed down device 3 between supports 2 and hold down 3 parallel to the plane e would be present. Thus, the module frame 4 then by tightening the screw 34 between the support 2 and the hold-down 3 be clamped. This can be on the specification of a predetermined torque of the screw 34 the clamping force with which the module frame 4 between downholder 3 and supports 2 is clamped, and consequently the contact pressure, by means of which the module frame 4 in the direction of the tempering device 6 is pressed, be targeted.

The support 2 , the downholder 3 and the module frame 4 are formed such that one parallel to the plane e the temperature control surface 60 through supports 2 and hold down 3 on the module frame 4 applied clamping force the module frame 4 on the temperature control surface 60 too pretentious. For this purpose, the module frame 4 on the downholder 3 facing side an inclined first contact surface 42 on, which with a parallel oriented counter surface 30 the hold-down 3 is in contact, and assigns the module frame 4 on the support 2 facing side opposite to the first contact surface 42 inclined second contact surface 40 on, which with a parallel oriented counter surface 20 of the support 2 is in contact with the first and second contact surfaces 42 . 40 from the temperature control surface 60 are oriented away. In other words, the first and second contact surfaces 42 . 40 so oriented that by means of by 2 and hold down 3 on the module frame 4 generated clamping, which is substantially parallel to the Temperierungsfläche 60 acts, the module frame 4 in the direction of the temperature control surface 60 is pressed. In other words, the module frame 4 in the direction of the temperature control surface 60 wedged.

Between the temperature control surface 60 and the module frame 4 is also an electrically insulating layer of a thermally conductive component 62 arranged. The thermally conductive component isolates the tempering device 6 against the battery cells 5 electrically and is sufficiently ductile, so that they unevenness in the surface of the Temperierungsfläche 60 and the module frame 4 compensates, and so a substantially full-surface contact between Temperierungsfläche 60 and the thermally conductive component 62 as well as between module frames 4 and the thermally conductive component 62 is present.

Preferably, the distance, which with completely screwed down device 3 between supports 2 and hold down 3 parallel to the plane e is present, such that without the insulating layer of the thermally conductive component 6 a slight or marginal play between tempering surface 60 and module frames 4 perpendicular to the plane e is present. This game is in the assembled state completely through the layer of thermally conductive component 6 filled. The thickness of the layer of the heat-conducting component 6 is greater than the game without them, so that the predetermined contact force between module frame 4 and temperature control surface 60 only by means of the heat-conducting component 6 is built. This ensures that it is when screwing down the hold-down 3 not to excessive pressure on the tempering device 6 and / or the module frame 4 comes. The heat-conducting component preferably has 6 ductile properties, such that due to the ductility of the thermally conductive component 6 Unevenness on the temperature control surface 6 and / or on the module frame 4 balanced and / or pressure or voltage peaks can be compensated.

On the tempering device 6 opposite side of the battery cells 5 is a module counter frame 7 for receiving the battery cells 5 on the module frame 4 arranged opposite side. The module counter frame 7 is by means of an abutment 8th in the direction of the temperature control surface 60 biased. The counter bearing 8th includes another support 80 and another downholder 84 , wherein the module counter frame 7 an inclined first contact surface 72 having, which with a parallel thereto oriented counter surface 86 further downholder 84 is in contact, and the module counter frame 7 has a contrary to the first contact surface 72 inclined second contact surface 70 on, which with a parallel oriented counter surface 82 the further support 80 is in contact with the first and second contact surfaces 72 . 70 of the module counter frame 7 from the temperature control surface 60 are oriented away.

Because the module counter frame 7 analogous to the module frame 4 between the other support 80 and the other downholder 84 is clamped, causes the orientation of the contact surfaces 70 . 72 and the counter surfaces 82 . 86 in that the module counter frame 7 in the direction of the temperature control surface 60 pressed. The module counter frame 7 pushes the battery cells 5 in the direction of the temperature control surface 60 , allowing a secure contact between temperature control surface 60 and battery cells 5 or module frame 4 achieved. By this pressing is made possible that between the battery cells 5 and the temperature control surface 60 a heat transfer via heat conduction via the direct contact is possible.

In 2a is a schematic detail view of the battery assembly 1 out 1 in the area of the holddown 3 shown. Here is by the reference numeral N a normal of the first contact surface 42 of the module frame 4 indicated. The normals N is conventionally perpendicular to the first contact surface 42 oriented. The first contact surface 42 is oriented in such a way that its normal N from the temperature control surface 60 points away. In other words, the normal closes N with the plane e an angle α greater than 0 ° and less than 90 °. In other words, through the first contact surface 42 one from the Temperierungsfläche 60 oriented wedge provided, which increases with increasing distance to the Temperierungsfläche 60 rejuvenated.

In 2 B is a schematic detail view of the battery assembly 1 out 1 in the area of the support 2 shown. Analogous to the description too 2a is herein by the reference numeral N a normal of the second contact surface 40 of the module frame 4 indicated. The normals N is conventionally perpendicular to the second contact surface 40 oriented. The second contact surface 40 is oriented in such a way that its normal N from the temperature control surface 60 points away. Accordingly, the normal closes N with the plane e an angle α 'of greater than 0 ° and less than 90 °. In other words, through the second contact surface 40 one from the Temperierungsfläche 60 oriented wedge provided, which increases with increasing distance to the Temperierungsfläche 60 rejuvenated. In the present case, the angle corresponds α the angle α '.

The first and the second contact surface 42 . 40 are thus oriented so that by means of by 2 and hold down 3 on the module frame 4 generated clamping, which is substantially parallel to the Temperierungsfläche 60 acts, the module frame 4 in the direction of the temperature control surface 60 is pressed. In other words, the means of clamping by support 2 and hold down 3 generated on the module frame 4 acting clamping force F _E in a force component parallel to the Temperierungsfläche 60 or their level e and in a pressing force F _A split, whose force vector in the direction of Temperierungsfläche 60 , thus perpendicular to the plane e is oriented. The module frame 4 is equal to the contact pressure F _A against the Temperierungsfläche 60 pressed. The contact pressure F _A calculated in accordance with F _A = F _E * sin α * cos α ,

For mounting the battery assembly 1 becomes the module frame 4 first loose on the support 2 placed. Subsequently, the hold-down 3 fitted and by means of the screw connection 34 towards the support 2 tightened and clamped. The module frame 4 slides during this clamping process with its contact surfaces 42 . 40 on the mating surfaces 20 . 30 in the direction of the temperature control surface 60 or the heat-conducting component 62 until he reaches the tempering surface 60 or the heat-conducting component 62 is applied. By further tightening the screw connection 34 the clamping of the module frame takes place 4 between supports 2 and hold down 3 so that the module frame 4 with the by adjusting the screw accordingly adjusting contact pressure F _A against the Temperierungsfläche 60 is pressed. By sliding the contact surfaces 42 . 40 on the mating surfaces 20 . 30 also takes place at the bottom and at the top of the module frame 4 a centering movement of the module frame 4 in the direction of the temperature control surface 60 ,

Alternatively, the angle α and the angle α 'also be different. For example, an angle α 30 ° and have an angle α '40 °. Also, only the first contact surface 42 be inclined so the angle α greater than 0 ° and less than 90 °, and the second contact surface 40 perpendicular to the plane e formed, the angle α 'thus be 90 °. Then only via the first contact surface is a contact force F _A generated on the module frame. Furthermore, only the second contact surface 40 be inclined, so that the angle α 'is greater than 0 ° and less than 90 °, and the first contact surface 42 perpendicular to the plane e trained, the angle α thus be 90 °.

3a schematically shows a detailed view of the abutment 8th the battery arrangement 1 out 1 in the area of the further hold-down 84 , and 3b schematically shows a detailed view of the abutment 8th the battery arrangement 1 out 1 in the area of the additional support 80 , Analogous to the comments on the 2a and 3a close the normals N the first contact surface 72 and the second contact surface 70 of the module counter frame 7 with the plane e the temperature control surface 60 indicated here by the plane indicated by the reference character E 'parallel shifted plane, the angle α or the angle α 'a. This generates the through the additional support 80 and the other downholder 84 on the module counter frame 7 generated clamping a displacement of the module counter frame 7 in the direction of the temperature control surface 60 , and when applying the module frame 4 and the battery cells 5 at the temperature control surface 60 or their heat-conducting component 62 analogous to in the 2a and 2 B described manner a contact force F _A by means of which the module counter frame 7 in the direction of the temperature control surface e is pressed.

If, as in this case, the angle α the first contact surface 42 and the angle α 'of the second contact surface 40 of the module frame 4 are the same size and the angle α the first contact surface 72 and the angle α ' the second contact surface 70 of the module counter frame 7 are the same size, there is a centering of the battery cells 5 parallel to the plane e , This ensures that the battery cells 5 exactly perpendicular to the temperature control surface 60 are arranged and with their front sides over the entire surface of the module frame 4 or the Temperierungsfläche 60 issue.

Out 4 is a schematic plan view of the battery assembly 1 out 1 refer to. The module frame 4 , the thermally conductive component 62 as well as the module counter frame 7 extend substantially over the entire width of the battery cells 5 , At the ends of the tempering device 6 each is a hold-down 3 and at the ends of the counter bracket 8th is each another hold-down 84 provided, each with a screw connection 34 in the direction of the support 2 are braced to the module frame 4 and the module counter frame 7 clamp and in the direction of Temperierungsfläche 60 to squeeze.

5 shows schematically a plan view of a battery assembly 1 according to a further embodiment. The battery arrangement 1 is essentially the same as 1 and 4 , each with a hold-down 3 as well as another downholder 84 are provided, which extend over the entire width of the tempering device 6 or the counter bearing 8th extend.

Out 6 is a schematic sectional view of a battery assembly 1 according to another embodiment, which substantially the battery assembly 1 out 1 equivalent. In the battery arrangement 1 according to 4 is also a plurality of tempering devices 6 perpendicular to the base 9 arranged, in 4 for example, a tempering device 6 is shown. The tempering device 6 has on both sides in each case a Temperierungsfläche 60 with a thermally conductive component 62 on, from both sides of the tempering device 6 one module frame each 4 with a plurality of battery cells 5 is arranged. The hold down 3 and the support 2 with respect to the tempering device 6 on both sides in each case a counter surface 20 . 30 which are oriented such that the module frames 4 from both sides against the respective temperature control surface 60 the tempering device 6 pressed. Furthermore, a plurality of abutments 8th provided, which also in the manner described above on both sides on both sides of the abutment 8th arranged module counter frame 7 Act.

In the present case is the base area 9 perpendicular to a vertical V , thus arranged horizontally. The temperature control surfaces 60 as well as the counter bearing 8th are parallel to the vertical V oriented. This results in a layer of horizontally arranged battery cells 5 one above the other in the direction of the vertical V allows.

Where applicable, all individual features illustrated in the embodiments may be combined and / or interchanged without departing from the scope of the invention.
