Description

[0001] Battery carrier component, battery carrier and method for producing a battery carrier component and a battery carrier

[0002] The present invention relates to a battery carrier component, in particular a battery carrier frame, for at least partial arrangement in a battery carrier and / or for connection to a battery carrier. The present invention also relates to a battery carrier for accommodating at least one battery cell serving as a drive energy storage device for an electrically powered vehicle. Furthermore, the present invention relates to a method for producing a battery carrier component and a method for producing a battery carrier.

[0003] Electrically powered vehicles of the type in question here typically carry a plurality of battery modules comprising battery cells that serve as propulsion energy storage devices and provide the electrical energy required for ferry operation. In particular, an electrically powered vehicle of the type in question here is an electric car, which is essentially powered exclusively by an electric motor. Alternatively, the aforementioned battery carrier can also be used in a hybrid vehicle, which has an internal combustion engine in addition to an electric motor.

[0004] Since battery cells / battery modules are usually very heavy, their placement in the vehicle not only places high demands on the vehicle's supporting structure from a static point of view, but also influences the dynamic forces occurring during ferry operation.

[0005] In terms of driving performance, placing the individual battery cells / battery modules in the floor area of ​​the vehicle has proven advantageous. To achieve this, battery trays are used that are essentially flat and plate-like. Such battery trays can be arranged in the floor area of ​​the vehicle and connected to the vehicle chassis.

[0006] Therefore, considerable demands are placed on the static and dynamic load-bearing capacity of the battery trays described above. The battery tray must not only be able to support the individual battery cells or battery modules, but also absorb the dynamic loads that arise during vehicle operation. Furthermore, the battery tray must provide the best possible protection for the highly flammable battery cells or battery modules in the event of an accident.

[0007] Accordingly, battery trays represent a critical component for the safety and functionality of vehicles. The aforementioned requirements for the manufacture of battery trays sometimes lead to the provision of complex battery tray geometries. Due to the complex geometries of battery trays, manufacturing processes are often used in which several components must be connected, particularly welded, to one another. However, the resulting joints can lead to leaks, meaning that the battery modules accommodated in the battery tray are not reliably protected against the ingress of liquids, especially water.

[0008] In this context, it has proven advantageous to manufacture a frame structure of the battery tray from at least one deep-drawn component, in particular from at least one deep-drawn sheet. Deep-drawing allows for a battery tray with only a few connection points, thus improving the tightness of the battery tray. However, such a manufacturing method is disadvantageous in that the deep-drawing process makes it almost impossible to produce essentially vertical battery tray walls, meaning that the edge areas of the battery tray cannot be equipped with battery modules or battery cells due to the resulting limited installation space.

[0009] Due to the limited installation space, the limits regarding constructive optimization of the corresponding edge area are quickly reached.

[0010] The present invention therefore aims to provide a battery carrier component and a battery carrier by means of which the edge region of the battery carrier can be advantageously utilized. Advantageous manufacturing methods for the battery carrier component and the battery carrier are also to be specified.

[0011] The aforementioned object is achieved according to a first aspect of the present invention in a battery carrier component, in particular a battery carrier frame for at least partial arrangement in a battery carrier and / or for connection to a battery carrier, in that the battery carrier component comprises: at least one core element, wherein the at least one core element comprises a metal and / or fiber material, in particular consists of a metal and / or a fiber material, and at least one jacket element at least partially surrounding the core element, wherein the at least one jacket element comprises plastic, in particular consists of plastic. For example, the plastic can be a fiber-reinforced plastic.

[0012] Such a hybrid design of the battery carrier component can reliably provide a structure for placement in a battery carrier and / or for connection to a battery carrier, resulting in a battery carrier with improved static and / or dynamic properties. In particular, this can, for example, improve the overall crush or crash performance of the battery carrier. The battery carrier component can also provide filler material in the area of ​​a battery carrier where battery cells cannot be arranged due to space constraints.

[0013] In addition, the battery carrier component can be used to secure connection points, such as busbars, which in turn can connect the various battery cell poles. Furthermore, the overall weight can be advantageously reduced while simultaneously improving the overall performance of the battery carrier component or battery carrier.

[0014] The at least one core element is, in particular, a sheet-like core element, which has preferably been formed into a specific structure. In particular, the core element comprises a steel or aluminum alloy.

[0015] The at least one core element can also be a fiber material, in particular a fiber mat, which has preferably been formed into a specific structure. For example, the fiber material is a fiber mat made of glass and / or carbon fiber.

[0016] It is also conceivable that at least one core element comprises both metal and fiber material.

[0017] Preferably, the at least one sheath element at least partially surrounds the at least one core element. In this respect, it is conceivable that one side of the core element and / or a part of the core element is not surrounded by the at least one sheath element.

[0018] In particular, the at least one jacket element is a

[0019] An injection-molded part that is molded around at least one core element. This allows the overall weight of the battery carrier component to be further reduced and a battery carrier component to be provided in a more cost-effective manner.

[0020] A preferred embodiment of the battery carrier component is characterized in that the battery carrier component is designed to bridge a region of a battery carrier not equipped with battery cells and / or a region of a battery carrier that cannot be equipped with battery cells. Particularly when designing a frame structure of a battery carrier comprising at least one deep-drawn sheet, otherwise unused installation space can be utilized to improve the performance of the battery carrier. It is preferred that the dimensions of the battery carrier component essentially correspond to the installation space to be bridged in the frame structure of the battery carrier.

[0021] In particular, the at least one casing element has at least one substantially tapered outer contour and / or a substantially tapered outer side. This allows the battery carrier component to advantageously bridge an edge region of a battery carrier that has only limited installation space.

[0022] A further preferred embodiment is characterized in that the at least one casing element has at least one receptacle for at least one battery cell and / or at least one battery module on its inner contour, in particular on a side facing a receptacle area for at least one battery cell and / or at least one battery module. In this way, the at least one battery cell and / or the at least one battery module can be securely fixed and protected without the need to attach further elements in the battery carrier component. The provision of such a receptacle has proven particularly advantageous in so-called "cell-to-pack" technology, in which the individual battery cells are arranged directly in the battery carrier without being combined to form individual battery modules.For example, battery cells, for example pouch battery cells, round cells and / or prismatic battery cells, can be securely fixed by means of the at least one holder, so that no further components have to be used to store the battery cells.

[0023] According to a further embodiment of the battery carrier component, the at least one receptacle corresponds to the outer contour of at least one battery cell, wherein the at least one receptacle is in particular substantially curved, particularly preferably semi-cylindrical. This allows the battery cells to be reliably fixed in the battery carrier component. A substantially semi-cylindrical shape is understood to mean a shape that has slight deviations from an ideal semi-cylindrical shape, for example design- and production-related deviations. Such a shape is particularly advantageous for accommodating individual battery cells. Furthermore, other shapes of the at least one receptacle are also conceivable and advantageous depending on other possible battery shapes, for example a rectangular or triangular shape, in particular with rounded corners.

[0024] A further advantageous embodiment is characterized in that the at least one core element comprises a steel alloy or an aluminum alloy, in particular consists of a steel alloy or an aluminum alloy, and / or that the at least one sheath element comprises injection-molded phenolic resin and / or injection-molded polyamide, in particular consists of injection-molded phenolic resin or injection-molded polyamide. The aforementioned materials of the at least one core element and / or the at least one sheath element result in a battery carrier component that is lightweight and can also absorb sufficient forces. For example, the injection-molded phenolic resin and / or the injection-molded polyamide has a fiber structure. A fiber content of the at least one sheath element in a range of 20 to 40 wt.%, in particular in a range of 25 to 35 wt.-%, has proven to be advantageous in terms of the rigidity and weight of the battery carrier component.

[0025] A further preferred embodiment is characterized in that the battery carrier component further comprises at least one means for connecting the battery carrier component to a battery carrier and / or means for connecting the battery carrier component to battery modules and / or other components of the battery, such as PCBs. A means for connection is, in particular, a means that can be used to connect the battery carrier component and battery carrier or the battery carrier component and battery to one another. For example, the at least one means for connecting the battery carrier component is designed as a through-hole, in particular as a through-hole having an internal thread, as an adhesive surface and / or as a component of a clip connection. As a result, the battery carrier component and battery carrier can advantageously be connected to one another by means of an adhesive connection, a screw connection, a rivet connection and / or a clip connection.

[0026] A further preferred embodiment is characterized in that the at least one core element extends over substantially the entire longitudinal axis of the battery carrier component. This makes it possible to provide sufficient stability and rigidity of the battery carrier component over the entire length of the battery carrier component. In particular, only the two end faces of the longitudinal sides of the at least one core element are covered with the at least one sheath element. It is preferred that the coating arranged on the end faces of the at least one core element does not exceed a thickness of 50 mm, in particular a thickness of 25 mm, particularly preferably a thickness of 10 mm.

[0027] In a further preferred embodiment, the at least one core element can extend only over part of the longitudinal axis of the battery carrier component. This allows for the production of smaller battery carrier components, which can then be arranged one behind the other in the edge regions of the battery carrier. This is advantageous, for example, from a manufacturing perspective.

[0028] A further preferred embodiment is characterized in that the at least one core element is manufactured in multiple pieces, in particular in two parts. This allows for advantages in terms of manufacturing technology, since the at least one shell element can be manufactured on smaller machines. A further preferred embodiment is characterized in that the at least one shell element has a substantially identical thickness on both sides of the at least one core element. In particular, the at least one core element is embedded substantially centrally in the at least one shell element. This has proven advantageous with regard to the absorption of loads by means of the battery carrier component.

[0029] A further preferred embodiment is characterized in that the at least one core element has projections on at least one of its longitudinally extending edges. Such projections can be particularly advantageous with regard to absorbing forces from the at least one core element. Alternatively, it is also preferred that the at least one core element is substantially flat on at least one of its longitudinally extending edges. This has proven particularly advantageous from a manufacturing point of view.

[0030] A further preferred embodiment is characterized in that the at least one core element has a substantially L-shaped or substantially U-shaped cross-sectional profile. By means of such a cross-sectional profile, at least one core element can advantageously be provided that reliably absorbs static and dynamic loads. With regard to sufficient rigidity of the at least one core element, it has further proven advantageous for the core element to have at least one central section with two legs formed thereon. The legs preferably extend at an angle of 80° to 120° to the central section of the at least one core element.

[0031] A further advantageous embodiment is characterized in that the at least one casing element substantially completely surrounds the at least one core element, in particular in that the at least one casing element is completely injection-molded around the at least one core element. This makes it possible to provide a battery carrier component in a manufacturingly advantageous manner that bridges the available installation space of the battery carrier.

[0032] A further advantageous embodiment is characterized in that the at least one core element has recesses, in particular through holes, for positive connection to the at least one sheath element. This allows the sheath element to be advantageously overmolded around the core element or fixed to the core element.

[0033] A further advantageous embodiment is characterized in that the at least one casing element at least partially has a profile structure for stiffening the battery carrier. The profile structure preferably comprises essentially horizontally running profile webs and / or essentially vertically running profile webs. The essentially horizontally and / or vertically running profile webs preferably essentially form a box profile or a honeycomb profile. By providing a profile structure, crash structures in particular can be created which absorb any forces generated in the event of a vehicle accident and protect the battery cells arranged in the battery carrier. In particular, the design of the profile structure as a box profile or honeycomb profile has proven advantageous with regard to production by injection molding and with regard to high energy absorption.

[0034] Preferably, the length of the substantially horizontally extending profile webs and / or the length of the substantially vertically extending profile webs vary relative to one another, so that the at least one battery carrier component can essentially optimally utilize the available installation space of the battery carrier. This also allows for an adapted profile structure, so that the battery carrier component can be stiffened more or less as needed. This allows the crash properties of the profile structure to be further optimized and the overall weight of the battery carrier to be reduced.

[0035] Furthermore, it is preferred that the at least one core element is only a component of the profile webs forming the outer sides of the battery carrier component, and that the profile webs arranged within these outer sides are formed solely by the at least one casing element. This leads to a reduction in the overall weight of the battery carrier component.

[0036] According to a second aspect of the present invention, the aforementioned object is achieved by a battery carrier for accommodating at least one battery cell serving as a drive energy storage device for an electrically powered vehicle, wherein the battery carrier is connectable to a chassis of the vehicle, and wherein the battery carrier comprises an aforementioned battery carrier component. Thus, a battery carrier can be provided in which the installation space not filled by battery cells and / or battery modules is advantageously utilized by the at least one battery carrier component.

[0037] A further advantageous embodiment is characterized in that the battery carrier comprises at least one substantially circumferential frame structure having longitudinal sides, transverse sides and a base region for forming a receiving region for at least one battery cell and / or at least one battery module, wherein the at least one frame structure comprises at least two deep-drawn frame parts.

[0038] The surface enclosed by the receiving area is preferably the surface which, when the battery carrier is installed in a vehicle, runs essentially horizontally between the surrounding frame structure and which can therefore accommodate at least one battery cell and / or at least one battery module. In particular, the surface of the receiving area is enclosed by the surrounding frame structure, wherein the surface of the receiving area is preferably delimited by the inner side surfaces of the longitudinal sides and by the inner side surfaces of the transverse sides of the surrounding frame structure and thus extends in particular within the inner side surfaces of the longitudinal sides and the transverse sides of the frame structure.

[0039] Preferably, the surrounding frame structure is formed substantially rectangular, wherein the longitudinal sides each run substantially parallel to one another and / or wherein the transverse sides run substantially parallel to one another.

[0040] By having the at least one frame structure comprise at least two deep-drawn frame parts, in particular at least two deep-drawn sheets, a battery carrier can be provided which is particularly tight due to only a few connection points and penetration of liquid can therefore be reliably prevented.

[0041] Preferably, the two deep-drawn frame parts, in particular the at least two deep-drawn sheets, are connected to one another, in particular by means of at least one weld seam.

[0042] A further preferred embodiment is characterized in that the at least one battery carrier component is arranged and / or formed in at least one edge region of the at least one battery carrier to bridge an area of ​​the battery carrier that is not to be equipped with battery modules. Preferably, the at least one edge region is characterized in that the installation space, in particular the installation height, is smaller than the installation space, in particular the installation height, of the receiving area for at least one battery cell or at least one battery module of the battery carrier. Preferably, the at least one edge region corresponds to the area of ​​the battery carrier in which the essentially deep-drawn side walls of the battery carrier are arranged.By arranging the at least one battery carrier component in the edge region, the otherwise unused installation space can be used advantageously and the performance of the battery carrier with regard to crash properties and load absorption can be improved.

[0043] The above-mentioned object is achieved according to a third aspect of the present invention by a method for producing a battery carrier component, in particular an aforementioned battery carrier component, wherein the method comprises the following steps: providing at least one circuit board, in particular a metal circuit board, for producing the at least one core element, wherein the at least one metal circuit board is in particular a metal sheet severed from a coil; forming the at least one metal circuit board into at least one core element, wherein the at least one core element has in particular a substantially L-shaped or a substantially U-shaped cross-sectional profile after the forming; and injection molding a plastic onto at least one surface of the at least one core element.This makes it possible to provide a battery carrier component in a manufacturing process that can be used to bridge installation space within a battery carrier. Further advantages and features of the method for producing a battery carrier component have already been mentioned in connection with the battery carrier component itself, so reference is made to the above with regard to these.The above-mentioned object is achieved according to a fourth aspect of the present invention by a method for producing a battery carrier, in particular an aforementioned battery carrier, wherein the method comprises the following steps: deep-drawing at least one sheet, in particular deep-drawing at least two sheets, to produce at least one frame structure having longitudinal sides, transverse sides and a base region for forming a receiving region for at least one battery cell and / or at least one battery module, connecting at least one aforementioned battery carrier component to the at least one deep-drawn frame structure to bridge areas of the battery carrier not to be equipped with battery modules. This enables the production of a battery carrier in a manner that is favorable in terms of production technology, wherein the battery carrier has advantageous tightness and also enables sufficient load absorption.Further advantages and features of the battery carrier component have already been mentioned, so that reference is made to the above with regard to these.

[0044] A preferred embodiment is characterized in that the method further comprises the following step: joining, in particular, materially bonding, the at least two deep-drawn sheets to produce the at least one frame structure. Such a joining method is particularly advantageous with regard to the tightness of the battery carrier. For example, the two deep-drawn sheets can be joined together by means of at least one weld seam.

[0045] Further advantages and features of the method for producing a battery carrier have already been mentioned in connection with the battery carrier itself, so that reference is made to the above with regard to these.

[0046] The above-described embodiments and exemplary configurations of all aspects of the present invention, which initially stand alone in principle, are also to be understood as disclosed in all combinations with one another.

[0047] Further advantageous exemplary embodiments of the invention can be found in the following detailed description of some exemplary embodiments of the present invention, particularly in conjunction with the figures. However, the figures appended to the application are intended only for the purpose of illustration and not to define the scope of the invention. The accompanying drawings are not necessarily to scale and are intended merely to reflect the general concept of the present invention by way of example. In particular, features contained in the figures should in no way be considered a necessary part of the present invention.

[0048] The invention is explained in more detail below with reference to exemplary embodiments of the drawings. They show schematically:

[0049] Fig. 1 is a schematic view of an embodiment of a battery carrier;

[0050] Fig. 2 is a schematic view of part of an embodiment of a battery carrier component in a perspective view;

[0051] Fig. 3 is a schematic view of the core element of the embodiment of the battery carrier component shown in Fig. 2 in a perspective view;

[0052] Fig. 4a is a sectional view of the embodiment of the battery carrier component shown in Fig. 2 in a perspective view; and

[0053] Fig. 4b shows a further sectional view of the embodiment of the battery carrier component shown in Fig. 2 in a front view. In the following description of the various embodiments according to the invention, components and elements with the same function and mode of operation are provided with the same reference numerals, even if the components and elements may differ in their dimensions or shape in the various embodiments.

[0054] Fig. 1 shows a schematic sectional view of an embodiment of a battery carrier 2. The battery carrier 2 has a substantially circumferential frame structure 4, wherein the frame structure 4 has longitudinal sides 6 and transverse sides 8 for forming a receiving area 10 for battery modules 12. It can be seen that the substantially non-vertical longitudinal sides 6 and transverse sides 8 result in edge areas 14 which cannot be equipped with battery modules 12 due to the limited installation space.

[0055] For example, the frame structure 4 may consist of one or more deep-drawn sheets. If several, in particular two, deep-drawn sheets are used to form a frame structure 4, these sheets may be connected to one another by means of a weld seam (not shown).

[0056] Therefore, battery carrier components 16 are arranged in these edge regions 14 for bridging purposes. A battery carrier component 16 is shown in detail in Figs. 2 to 4b.

[0057] The battery carrier component 16 has a core element 18 and a casing element 20. The core element is made, in particular, of metal or plastic. For example, the core element can be made of a steel alloy or an aluminum alloy.

[0058] It can be seen that the core element 18 extends over substantially the entire length or the entire longitudinal axis of the battery carrier component 16. Furthermore, the core element has a substantially L-shaped cross-sectional profile with a central section 22 and two legs 24 and 26 formed on the central section 22. The leg 24 has substantially the same width as the central section 22 and extends substantially orthogonally to the central section. The leg 26 has approximately half the width of the central section 22 and extends in the longitudinal direction of the battery carrier component 16 substantially at an angle of between 100° and 130° to the central section 22.

[0059] Furthermore, the edges 28 and 30 of the two legs 24 and 26, which extend essentially in the longitudinal direction, are essentially flat and have no projections.

[0060] Furthermore, recesses in the form of through holes 31 are provided in the leg 28, which can further improve the positive connection between the core element 18 and the jacket element 20.

[0061] It can be seen that the sheath element 20 essentially completely surrounds the core element 18. The sheath element is preferably made of an injection-molded plastic, which plastic may also be fiber-reinforced. For example, it may be injection-molded phenolic resin or injection-molded polyamide.

[0062] By means of the casing element 20, means for connection are further provided, namely an adhesive surface 32, by means of which the battery carrier component 16 can be connected to the battery carrier 2.

[0063] The casing element 20 further comprises a profile structure 34 for stiffening the battery carrier component 16. It can be seen that the profile structure 34 forms a box profile. The profile structure 34 is composed of essentially vertically extending profile webs 36, wherein the profile webs 36 extend essentially orthogonally to one another to form a box profile. Furthermore, the profile webs 36 arranged on the transverse side 8 of the battery carrier 2 are beveled, so that the outer contour of the battery carrier component 16 corresponds to the inner contour of the edge regions 14 of the battery carrier 2.

[0064] The exemplary embodiments of the present invention described in this specification are to be understood as disclosed both individually and in all combinations with one another. In particular, the description of a feature encompassed by an embodiment should not be understood in this case - unless explicitly stated otherwise - to mean that the feature is essential or essential for the function of the embodiment. The sequence of the method steps described in this specification in the individual flow diagrams is not mandatory; alternative sequences of the method steps are conceivable. The method steps can be implemented in various ways; for example, an implementation in software (by program instructions), hardware, or a combination of both is conceivable for implementing the method steps.

The phrase "at least partially" encompasses both "partially" and "fully." The phrase "and / or" is intended to indicate that both the alternative and the combination are disclosed, thus "A and / or B" means "(A) or (B) or (A and B)." A plurality of units, persons, or the like, in the context of this specification, means multiple units, persons, or the like. The use of the indefinite article does not exclude a plurality.
