Description

The invention relates to a battery arrangement in a vehicle comprising at least two body beams of the vehicle, between which a receiving space is located, at least one battery which is arranged at least in regions in the receiving space between the body beams, wherein a distance between a body beam and a boundary surface of the battery is located at least on one side of the battery, and at least one fixing element which bridges or fills the distance in an installed state and can be transferred into an installed state in which the fixing element does not bridge or fills the distance, or only partially. The invention further relates to a vehicle having a battery arrangement and to a method for mounting a battery in a vehicle.In vehicles, batteries having a high weight are often required. Such batteries may be, for example, drive batteries of an electrically driven vehicle or of a hybrid vehicle. Batteries are preferably arranged in the lower region of the vehicle on account of their large size and high weight, in order to achieve a deep overall center of gravity of the vehicle. For example, a battery can be placed between two body supports, in particular between two sills, in the vehicle. In order to be able to mount the battery between two body carriers and, if appropriate, also disassemble it, clearance in the form of a spacing is required in order to enable a movement of the battery between the body carriers. This play required for assembly, however, entails disadvantages in the event of an accident of the vehicle. A load which acts on the vehicle in the event of an accident cannot be forwarded from the vehicle body supports to the battery and vice versa via the distance or the clearance. The load or energy which acts in the event of an accident is thus forwarded in other ways and can lead to deformations and damage there. In addition, in the event of an accident, mass forces acting on the battery cannot be passed on to load-bearing parts of the vehicle, or can be passed on only with difficulty.DE 10 2012 001 596 A1 describes an energy-absorbing protective element which is arranged between the vehicle body and the battery. The protective element can be filled by a medium, in particular by compressed air, and absorbs load or energy in the event of an accident.DE 10 2014 112 741 A1 describes a motor vehicle having a battery installed in the underbody. In this motor vehicle, a compressed air storage element is arranged along the longitudinal sides between the battery and adjacent body supports. The compressed air storage element serves as a protection for the battery in the event of a side impact.DE 10 2018 218 789 A1 describes a vehicle having a battery arranged between two longitudinal vehicle body members. Between the battery and the longitudinal body beams, a coupling element is arranged which, invariable in its shape, is adapted to the shape of the battery and the body of the vehicle.DE 10 2022 110 714 A1 describes a fastening arrangement for a component, which fastening arrangement comprises a two-part filler element, which is arranged between the component and a body element. The two parts of the filling element bear against one another via inclined contact surfaces and are adjustable in their relative position with respect to one another. Furthermore, the fastening arrangement additionally comprises at least one force-lockingly acting fastening element.The object of the invention is to propose solutions by means of which accident safety in vehicles having a battery can be improved and the assembly and disassembly of the battery in the vehicle is simplified.This object of the invention is achieved by a battery arrangement in a vehicleat least two body carriers of the vehicle, between which a receiving space is located,at least one battery which is arranged at least in regions in the receiving space between the body supports, wherein a distance between a body support and a boundary surface of the battery is located at least on one side of the battery,at least one fixing element which bridges or fills the distance in an installed state and can be transferred into an assembled state in which the fixing element does not bridge or only partially bridges or fills the distance, wherein the fixing element is designed to be rigid at least in regions.It is provided that the fixing element comprises a body element which abuts the body support in the installed state and a battery element which abuts the battery, wherein the body element and the battery element are each designed to be rigid at least in regions, wherein the relative position of the battery element to the body element and thus an outer dimension of the fixing element which extends between the body support and the battery in the installed state can be adjusted via an adjustment mechanism which connects the battery element to the body element, wherein the fixing element is arranged in the receiving space at least in regions in the installed state and fills the distance and does not fill the distance or only partially fills the distance in the installed state and the outer dimension in the installed state substantially corresponds to the distance and is smaller than the distance in the installed state.According to the invention, it is provided that the body element and the battery element are arranged side by side in regions in the direction of the distance, wherein the adjustment mechanism comprises a variable-size chamber arranged between the body element and the battery element, which can be filled with a medium and an enlargement of the chamber brings about an enlargement of the external dimension by filling with the medium, in that the chamber presses the body element and the battery element apart in the direction of the distance and more medium is present in the chamber in the installed state than in the installed state, or the body element and the battery element are arranged side by side in regions in the direction of the distance, wherein the adjustment mechanism comprises a linear drive arranged between the body element and the battery element and an actuation of the linear drive changes the relative position of body element and battery element to one another and thus the external dimension, wherein the linear drive comprises an electric motor or a drive that can be actuated manually.The battery arrangement according to the invention serves for the secure fastening of a battery in a vehicle. The vehicle may be, for example, a motor vehicle, such as an automobile. However, the battery arrangement can also be arranged in another vehicle, for example in a trailer or wagon. The battery arrangement comprises at least two body carriers of the vehicle and a receiving space arranged therebetween. The body supports are load-bearing structures of the vehicle. The body supports can be formed, for example, by sills of an automobile. A receiving space arranged between these body supports is the location at which a battery is arranged. This receiving space is preferably located in the lower region or in the underbody of the vehicle. In the assembled state, the battery fills only a part of the receiving space. On at least one side of the battery, there is a distance in the receiving space between a body support and a boundary surface or outer surface of the battery. Preferably, a distance is arranged between the battery and the respective adjacent body support on two mutually opposite sides of the battery in order to enable simple assembly and disassembly of the battery in the receiving space. Battery is understood to mean an assembly which has an electrical energy store which is arranged in a housing. Usually, the connection and fastening of the battery in the receiving space takes place via partial regions of the housing of the battery. In the following, the assembly with the electrical energy store and the associated housing is referred to simply as a battery. The term "distance" is to be understood as meaning both a dimension which extends in the free space between a body support and a boundary surface of the battery and the cavity which is arranged between the battery and the body support. The dimension of the distance preferably extends between a partial region of the battery and a partial region of a body support arranged parallel thereto. The dimension of the distance can also be used as a directional indication, wherein the direction of the distance is preferably oriented perpendicular to the direction of travel of the vehicle. For other applications, the direction of the distance can also be oriented parallel to the direction of travel. The cavity defined by the distance is usually only filled with air, unless a fixing element is already introduced into the distance. According to the invention, the battery arrangement comprises at least one fixing element which can assume two states: an installation state which is set when the battery arrangement is assembled, and an assembly state in which the battery can be introduced into the receiving space or removed therefrom. The fixing element is a geometric, physical element which has at least one variable dimension in order to enable a transfer from the installed state to the installed state and vice versa. In the installed state, the fixing element completely bridges the distance or fills it completely. In this way, in the installed state, there is a closed load path between the body support and the battery. This closed load path is produced by a positive connection between these elements and enables a transmission of load or energy which acts on the assemblies thereof in the event of an impact or other accident of the vehicle. By means of this load path provided by the fixing element, the two body carriers which are preferably arranged parallel to one another are connected to one another by the battery arranged therebetween. In the assembled state of the fixing element, a part of the distance or cavity remains between the battery and an adjacent body support, since the fixing element does not bridge or fills the distance, or only partially. In the assembled state, there is thus play in order to mount or disassemble the battery in the receiving space. According to the invention, the fixing element is designed to be rigid at least in regions. Rigid is to be understood here as meaning that the fixing element is substantially non-deformable. This rigid design brings about an efficient transmission of compressive forces via the fixing element between the body support and the battery. Due to the rigid design, the fixing element conducts load and energy directly on without absorbing or damping the load or energy by deformation. The fixing element can be embodied as completely rigid or have two or more rigid partial regions which are embodied as movable relative to one another and are embodied as adjustable in their position and can subsequently be fixed in their position relative to one another.The battery arrangement according to the invention mechanically couples the battery in a vehicle to two body carriers, as a result of which a load path is provided which, in the event of an accident, enables the transmission of load and energy in the vehicle. In this way, the accident safety of the vehicle is improved and damage to the body and battery is reduced. At the same time, the fixing element, which is variable in its size, shape or position, enables simple and rapid assembly and disassembly of the battery in the receiving space. The battery arrangement is suitable for vehicles in which the battery remains in the vehicle for a longer time, as well as for vehicles in which the battery is periodically replaced. Such a regular replacement of the battery can be used, for example, in battery replacement systems in order to increase the range of an electrically driven vehicle in a very short time by simple replacement of the battery.In one embodiment, it is provided that the body supports extend substantially in the direction of travel of the vehicle, in particular are designed as sills, and the distance is located in a direction perpendicular to the direction of travel of the vehicle in the receiving space between a body support and the battery, wherein in the assembled state of the fixing element at least a partial region of the distance remains in order to enable assembly or disassembly of the battery in the receiving space. In this embodiment, the distance is arranged in a direction perpendicular to the direction of travel of the vehicle between a body support and the battery and also extends in this direction. The introduced or bridging fixing element is thus part of a load path on which loads can be passed on in the event of a side impact on the vehicle. Alternatively, the distance can also extend in another horizontally oriented direction, for example in the direction of travel.In a further embodiment, it is provided that the fixing element is designed to be completely rigid and is movably connected to a body support, wherein in the installed state the fixing element bridges the distance and abuts the battery or is connected in a form-fitting manner to a partial region of the battery and in the assembled state the fixing element is separated from the battery. The fixing element can consist of a single, rigid part. In this embodiment, the fixing element is of cost-effective manufacture and robust design.Furthermore, it can be provided that the fixing element is fastened to the fixing element in a rotatable and / or linearly displaceable manner and can be transferred from the installed state to the installed state and vice versa by a rotational movement and / or a translatory movement. This embodiment relates to a fixing element of completely rigid design. The fixing element is movably attached to a body support and can be transferred from the installed state to the installed state by a simple rotational movement or displacement movement. In addition, the fixing element can be fixed in its position at least in the installed state. A connection of the fixing element to the body support via a joint is particularly favorable. When converting from the installed state into the assembled state and vice versa, the fixing element and the joint axis are rotated, which is preferably arranged horizontally. The fixing element can be designed in the form of a bracket or hook, which in the installed state bridges the complete distance and in the installed state is folded away from the battery in order to allow simple assembly and disassembly.According to the invention, it is provided that the fixing element comprises a body element which bears against the body carrier in the installed state and a battery element which bears against the battery, wherein the body element and the battery element are each designed to be rigid at least in regions, wherein the relative position of the battery element with respect to the body element and therefore an outer dimension of the fixing element which extends between the body carrier and the battery in the installed state can be adjusted via an adjustment mechanism which connects the battery element to the body element, wherein the fixing element is arranged in the receiving space at least in regions in the installed state and fills the distance and does not fill the distance or only partially fills the distance in the installed state and the outer dimension in the installed state substantially corresponds to the distance and is smaller than the distance in the installed state. In this embodiment, the fixing element comprises two rigid elements movable relative to one another: a body element and a battery element. Both elements are connected to one another by an adjustment mechanism which enables adjustment of an outer dimension which extends in the direction of the distance in the installed state. The adjustment mechanism allows the relative position of the two elements to be adjusted with respect to one another such that the fixing element either completely fills the distance or else the outer dimension is smaller than the distance and therefore there is play for the movement of the battery in the receiving space in the assembled state.In one embodiment, it is provided that the body element and the battery element are each configured in sections in a wedge-shaped manner, wherein the wedge-shaped regions are oriented at an angle to the distance and the adjusting mechanism has a tension element acting perpendicular to the distance, which pulls the body element and the battery element in a direction perpendicular to the distance towards one another upon actuation and upon actuation of the tension element the wedge-shaped regions of body element and battery element slide on one another and thereby translate the relative movement of body element and battery element perpendicular to the distance towards one another into a relative movement of body element and battery element in the direction of the distance away from one another, and increase the outer dimension. In this embodiment, a wedge shape of the body element and battery element is used to translate a movement generated by the adjustment mechanism in a direction perpendicular to the distance into a change in the outer dimension of the fixing element in the direction of the distance. The adjustment mechanism is of simple construction and comprises a tension element which can be designed, for example, as a threaded bolt with a wing nut. Upon actuation of the adjustment mechanism, the body element and the battery element are moved towards each other in the direction of the longitudinal axis of the tension element. The inclined surfaces on the elements slide on each other and thus translate the applied movement into a relative movement of the two elements away from each other in the direction of the distance. For the transfer into the installed state, the adjusting mechanism is actuated until the outer dimension corresponds to the distance and the fixing element thus completely fills the distance. As an alternative to a two-part fixing element, in which both parts comprise a wedge-shaped region, a wedge-shaped partial region can also be provided fixedly connected to the body support or the battery, which partial region interacts with a wedge-shaped element of the fixing element.In an alternative according to the invention, it is provided that the body element and the battery element are arranged side by side in regions in the direction of the distance, wherein the adjusting mechanism comprises a variable-size chamber arranged between the body element and the battery element, which can be filled with a medium and an enlargement of the chamber by filling with the medium brings about an enlargement of the outer dimension in that the chamber presses the body element and the battery element apart in the direction of the distance and in the installed state more medium is present in the chamber than in the installed state. In this embodiment, two rigid elements of the fixing element are provided, which are arranged side by side in regions and on the other hand overlap in regions or penetrate into one another. The adjusting mechanism comprises a variable-size chamber which is sealed off from the outside and can be filled with a medium, such as oil or air. A change in the outer dimension is achieved by introducing medium into this chamber or removing medium from it. The outer dimension can thus be continuously adjusted by the amount of medium contained in the chamber. In this embodiment, the fixing element can be formed, for example, by a hydraulic or pneumatic cylinder which is arranged with its direction of action parallel to the distance.Alternatively, it is possible according to the invention for the body element and the battery element to be arranged side by side in regions in the direction of the distance, wherein the adjusting mechanism comprises a linear drive arranged between the body element and the battery element and an actuation of the linear drive changes the relative position of the body element and battery element with respect to one another and thus the outer dimension, wherein the linear drive comprises an electric motor or a drive actuatable manually. In this embodiment too, the fixing element comprises two rigidly designed elements which are arranged side by side in regions. The adjusting mechanism comprises a mechanically acting linear drive, by means of which the external dimension of the fixing element can be adjusted. For example, this linear drive can comprise a toothed rack and a toothed wheel connected thereto, wherein, when the toothed wheel is rotated, the toothed rack is moved translationally in the direction of the distance. The linear drive can comprise an electric motor or a manually actuatable drive. The linear drive is additionally designed to be fixable or lockable at least in the installed state.The object of the invention is furthermore achieved by a vehicle having a battery arrangement according to one of the embodiments described above, wherein the distance between at least one body support and the battery is preferably oriented perpendicular to the direction of travel of the vehicle. The vehicle according to the invention having a battery arrangement has a significantly increased accident safety since the battery arrangement provides a load path for forwarding loads and energies arising in the event of an accident. In the installed state, loads are thus transferred through the battery arrangement in the event of an accident and deformations at the components of the battery arrangement are thus reduced or avoided. Moreover, in the assembled state, it is possible to easily install, remove, or replace the battery in the vehicle.The object of the invention is finally achieved by a method for mounting a battery in a vehicle, wherein a battery arrangement according to one of the embodiments described above is used for carrying out the method, comprising the method steps A) transferring the at least one fixing element into the mounting state, B) introducing the battery into the receiving space between two body carriers of the vehicle, wherein the distance between the battery and at least one body carrier serves as play during the introduction, C) transferring the fixing element into the mounting state, in which the fixing element bridges or fills the distance, whereby the battery is fixed in the receiving space in a positive-locking and / or non-positive-locking manner between the body carriers.The method according to the invention serves for mounting or installing a battery in a vehicle. The process is preferably carried out in the stated sequence of process steps A) to C). The method may be performed in reverse order to disassemble or remove a battery in a vehicle from the vehicle. For the replacement of a battery in a vehicle, the method can first be carried out for removal in the reverse sequence of method steps C) to A) and then for installation of the battery in the sequence of method steps A) to C).In a first method step A), at least one fixing element is transferred into the assembled state, in which it does not fill up or bridge the complete distance.In a second method step B), the battery is now introduced into the receiving space. The spacing serves as a clearance in order to be able to introduce the battery into the receiving space without damage.Finally, in a third method step, the fixing element is transferred into the installed state, whereby a continuous load path is provided between the body support and the battery. The method according to the invention is simple to carry out using the battery arrangement, so that the mounting of the battery in the receiving space can be carried out quickly and reliably. After carrying out the method, the vehicle with the battery has increased accident safety, since the battery is fixed in the receiving space in a positively locking and / or force-locking manner.Features, effects and advantages disclosed in connection with the battery arrangement and the vehicle are also considered to be disclosed in connection with the method. The same applies in the opposite direction, features, effects and advantages which are disclosed in connection with the method, are also considered to be disclosed in connection with the battery arrangement and the vehicle.The invention is schematically illustrated in the drawings by way of embodiments and will be further described with reference to the drawings. It shows: FIG. 1 shows a schematic view of a possible embodiment of a battery arrangement according to the invention, FIG. 2 is a schematic view of an alternative embodiment of a battery arrangement which is not according to the invention.FIG. 1 shows a schematic view of a possible embodiment of a battery arrangement 1 according to the invention. In FIG. 1, a battery arrangement 1 can be seen as viewed in the direction of travel of a vehicle F. In the middle, a battery 13 is located, which comprises battery cells accommodated in a battery housing. Details of the battery housing and the individual battery cells are not shown. On the outer left and on the outer right edge there is a respective body support 11 of the vehicle F, which extends here in the direction of travel, that is to say into the drawing plane and out of the drawing plane. Between the two vehicle body supports 11 there is a receiving space 12 in which the battery 13 is accommodated. Due to the high weight of the battery 13, the battery arrangement 1 is preferably arranged in the underbody of the vehicle F, wherein the two body supports 11 are preferably formed by sills. A distance A is located between the battery 13 and each of the two body supports 11 This distance A serves, in the assembled state, to enable sufficient play for the assembly and disassembly of the battery 13 in the receiving space 12. In the embodiment shown, the distance A extends perpendicular to the direction of travel of the vehicle F. In FIG. 1, the installation state of the battery arrangement 1 is shown, in which a fixing element 14 is attached in or adjacent to the two of the distances A. The fixing element 14 forms a bridge for transmitting load or energy between a body support 11 and the battery 13 over the distance A in the event of an accident of the vehicle F. In order to enable a reliable and reliable transmission of load and energy, the fixing element 14 is at least partially rigid and is thus very well suited for the transmission of compressive forces. In FIG. 1, fixing elements 14 of different design are arranged in or at the two distances A. In this way, two different embodiments of fixing elements 14 can be described with reference to a figure. Preferably, however, if two distances A are present, identically designed fixing elements 14 are used for connecting battery 13 and vehicle body supports 11 in receiving space 12. On the right side, a completely rigid fixing element 14 is seen, which bridges the right distance A. This fixing element 14 is rotatably movably connected to the right body support 11 via a joint. The end of the fixing element 14 facing to the left is introduced in regions into an undercut in the battery 13, as a result of which the battery 13 and the fixing element 14 are connected to one another in a positive-locking manner in the installed state shown. In order to transfer the fixing element 14 into the mounted state, the positive connection between the battery 13 and the fixing element 14 can be canceled and the fixing element 14 can be folded downward about the joint in a rotational movement. In this downwardly folded state, the fixing element 14 then no longer bridges the distance A and thus enables the battery 13 to be mounted or dismounted in the receiving space 12. The fixing element 14 can be transferred either manually or by an automatic mechanism from the installed state to the installed state and vice versa.Arranged at the left-hand distance A in FIG. 1 is a fixing element 14 according to the invention, which comprises two rigid partial regions which are connected to one another in a movable or shape-changing manner. This fixing element 14 comprises a body element 14 abearing against the body support 11 and a battery element 14 bbearing against the battery 13. The fixing element 14 furthermore comprises an adjusting mechanism 14 c, which is not illustrated and arranged in the interior and which enables an adjustment of the relative position from the body element 14 ato the battery element 14 b. The fixing element 14 has an outer dimension AM which extends in the direction of the distance A in the illustrated installed state. In the installed state shown, the fixing element 14 fills the left-hand distance A. The adjusting mechanism 14 cin the interior comprises a variable-size chamber which is filled with medium. If more of this medium is introduced into the chamber, this medium increases and thus presses the body element 14 aand the battery element 14 bpart from one another, so that the external dimension AM increases. If, on the other hand, medium is removed from the chamber, this decreases, which in turn leads to a decrease in the outer dimension AM. In this way, by changing the outer dimension AM, the fixing element 14 shown on the left can be transferred from the installed state into the installed state and vice versa. The medium can be, for example, hydraulic oil, water or air. The dispensing and filling of the medium into the variable-size chamber can be effected by means of a hand pump or an automatic, motor-driven mechanism. As an alternative to the variable-size chamber fillable with a medium, the adjustment mechanism 14 cmay also be configured as a mechanical linear drive in the interior of the left fixing element 14, which enables an adjustment of the outer dimension AM.FIG. 2 shows in a schematic view an alternative embodiment of a battery arrangement 1, which is not according to the invention. The battery arrangement 1 shown in FIG. 2 differs from the battery arrangement 1 in FIG. 1 in the embodiment of the two fixing elements 14. In FIG. 2, too, the two fixing elements 14 are designed differently or are oriented differently relative to the battery 13 and a body support 11. Both fixing elements 14 shown in FIG. 2 have a rigid body element 14 athat bears against a body support 11, a rigid battery element 14 bthat bears against the battery 13, and an adjusting mechanism 14 cthat connects these two elements. In these embodiments as well, an outer dimension AM of the fixing elements 14 extending in the direction of the distance A is designed to be adjustable and variable. In the case of both fixing elements 14, both the body element 14 aand the battery element 14 bare configured in a wedge-shaped manner in regions, wherein the wedge-shaped regions are oriented at an inclination to the distance A. This wedge shape can be seen well in the case of the right fixing element 14, since the wedge-shaped regions are designed inclined with respect to the vertical. In the case of the left-hand fixing element, the wedge-shaped regions are designed inclined with respect to the horizontal direction of travel, as a result of which the wedge shape is not visible in the state shown. The two fixing elements 14 each comprise an adjusting mechanism 14 chaving a tension element which connects the body element 14 aand the battery element 14 bto one another in a direction perpendicular to the distance A and pulls them towards one another when actuated. The tension element can be designed, for example, as a threaded bolt with a nut screwed onto it. Upon actuation of the adjusting mechanism 14 c, the body element 14 aand the battery element 14 bare moved towards one another in a direction perpendicular to the distance A and this movement is translated into a movement parallel to the distance A by sliding the wedge-shaped regions towards one another. As a result of this movement parallel to the distance A between the body element 14 aand the battery element 14 b, the outer dimension AM changes and the fixing element 14 can in each case be transferred from the mounted state into the installed state and vice versa. In the fixing element 14 shown on the left, the tension element of the adjusting mechanism 14 cis oriented horizontally, parallel to the direction of travel, whereas the tension element of the adjusting mechanism 14 cis oriented in the right fixing element in the vertical direction, perpendicular to the direction of travel. The actuation of the adjustment mechanism 14 cmay be performed by hand, for example by applying a rotational movement to a wing nut on the tension element. Alternatively, an automatically operating mechanism can also be provided which actuates the adjusting mechanism 14c. It is possible for the body element 14 aor battery element 14 bto be fixedly connected to the body carrier 11 or the battery 13 and for the respective other element to be designed to be movable with respect thereto. Finally, it is also possible to arrange a surface arranged in a wedge shape on a body support 11 or on the battery 13. In this case, the fixing element 14 can be of simplified design and comprise only a wedge-shaped element 14 aor 14 band an adjusting mechanism 14 c.
