[0001] The invention relates to a device in the form of a sliding gate and a method for dismantling a Battery module in a vehicle. For the purposes of registration, a battery module is defined as part of a battery system (HV Battery) which provides an electric motor to drive the vehicle. The vehicle is This means it is either a purely electric vehicle or a hybrid vehicle.

[0002] An embodiment of a battery system according to the prior art is known, for example, from the document CN 2 04 375 869 U. This discloses a cell module (battery cell) in a high-voltage battery of a motor vehicle, The cell module is arranged in a housing (battery pack shell). A maintenance housing is attached to the housing (maintenance box). The housing comprises two base plates (base wall).

[0003] If such battery systems are damaged, they must be replaced completely or at least partially. Patent document CN 1 07 256 992 A discloses an auxiliary tool (lifting module) for replacing a high-voltage battery (lithium battery) of a motor vehicle. The auxiliary tool is designed in such a way that only a certain offset in vertical direction. The auxiliary tool includes two base plates (support plate). The exchange of a However, the entire battery system is disadvantageous, as only part of the system, for example individual Battery modules would have to be replaced.

[0004] Therefore, it is more sensible to remove only individual damaged battery modules from the battery system (battery) and replace it to avoid replacing the entire battery. Document US 2022 / 0 247 discloses this. 028 A1 an auxiliary tool for replacing a cell module (battery module) in a high-voltage battery (battery pack) of a motor vehicle, wherein the high-voltage battery comprises a housing (battery pack housing). The housing comprises two Base plates. The auxiliary tool is removably fixed to a base plate using a fastener (bolt).

[0005] The battery is usually arranged on a battery frame, which is particularly characterized by its longitudinal beams in the area of ​​the vehicle sills, with an underrun protection still arranged on the battery frame which serves as a base for the battery and protects it from impacts from the underbody. Replacing the usually Battery modules installed transversely to the direction of travel are moved using a mobile workshop crane (crane), which Using special lifting tools, the battery should be positioned exactly in the center of gravity and in balance krant. In order to reduce costs and effort, an important goal when removing a battery module is to use as little to damage other elements so that as many of the undamaged components as possible can be reused.

[0006] However, new cooling concepts for the battery modules provide that the individual battery modules are fluidically are connected to each other via cooling channels and not just via a central cooling line, for example left and right of the cell modules in the area of ​​the sills. The document DE 10 2017 203 519 A1, for example, discloses a Cell module in a high-voltage battery for a motor vehicle, wherein the cell module has an air-flow cooling channel. The coolant flows from one battery module to the other at these fluidic connections, which is why they are Coolant transfer points are sealed by a sealing element, which is a Prevents coolant from escaping during transfer. The sealing element must accommodate the positional tolerances of the battery modules. can compensate.

[0007] Due to the sealing elements which seal the battery modules arranged in the transverse direction of the vehicle longitudinal direction of the vehicle, but would be damaged when lifting the battery modules in the vertical direction This means that only clusters of cell modules could be exchanged, which in turn means that Cell modules which are connected in such a network with a damaged module, but are not themselves are damaged, would also have to be replaced. Such a procedure is therefore uneconomical.This text has been copied by the DPMA from the original sources. It does not contain any drawings. The tables and formulas may be of unsatisfactory quality.

[0008] Furthermore, the document DE 10 2009 040 197 A1 discloses a method for assembling and implicitly also for Disassembly of battery modules of a battery, wherein the battery modules (cell modules) are inserted into Rails of an assembled module carrier are attached to a carrier housing of the module carrier and thereby a The mounting direction of the battery modules can be either horizontal or vertical. Alternatively, also a fastening option between the module carrier and the battery module by hooking a retaining lug and a subsequent swiveling in. Accordingly, disassembly by swiveling out and unhooking is implicitly revealed.

[0009] Document DE 10 2018 119 544 A1 relates to a method for assembling and implicitly also for disassembling Battery modules that are connected via coolant coupling elements with O-ring seals can be plugged and unplugged again. A device for plugging or unplugging the battery modules is not revealed.

[0010] The document DE 10 2021 204 894 B3 discloses a lifting device for dismantling a battery module, which is designed to exert a lifting force on a gripper unit for a levering operation, in the context of which the The adhesive bond between the battery module and the housing base caused by a thermal paste is released.

[0011] From the document DE 10 2021 113 212 A1 a disassembly device for disassembling a battery module is known, wherein the device comprises a vacuum unit to create a negative pressure in an area of ​​a carrier while applying a pulling force to remove the battery module from the carrier.

[0012] From the document DE 10 2012 012 819 A1 a gripping device with gripping elements for gripping a battery module located between the gripping elements.

[0013] It is therefore an object of the present invention to provide a device and a method for dismantling a battery module in a vehicle, which allows a single battery module to be connected with simple and inexpensive means without damaging other elements of the battery module.

[0014] The object is achieved by the subject matter of the independent claims. Advantageous embodiments are are contained in the subclaims. It should be noted at this point that the disclosure of advantageous Embodiments of the device according to the invention also as a disclosure of advantageous embodiments of the method according to the invention, even if the embodiment is characterized by a device feature formulated feature is disclosed. The same applies in the reverse case.

[0015] The device according to the invention for disassembling a first battery module of an HV battery in a Vehicle from a battery frame with an underrun protection arranged thereon and under a first Battery module arranged sealing contours has at least one base plate and one fastening element, wherein the fastening element is designed to releasably fasten the base plate to the battery frame in such a way, that it is arranged on an end face of the first battery module. In the case that the end face is a flat surface is designed, the base plate is arranged plane-parallel to the end face.

[0016] Furthermore, the device according to the invention has at least one guide element which is designed is to be connected to the end face of the first battery module on which the base plate is arranged, wherein the The base plate and the guide element are arranged in such a way that the guide element is guided by a link of the This text has been copied by the DPMA from the original sources. It does not contain any drawings. The tables and formulas may be of unsatisfactory quality. Base plate protrudes and the backdrop has a first section which extends at least partially in the vertical direction, and a second section which extends at least partially in the transverse direction, which are designed to to guide the guide element at least in the transverse direction and one vertical direction.

[0017] The term transverse direction refers to a horizontal direction which is transverse to the longitudinal direction of the The longitudinal direction is defined by the end face on which the base plate is placed, so that the longitudinal direction is perpendicular to the front surface. Accordingly, the vertical direction refers to a vertical direction, which is perpendicular to the transverse and longitudinal directions. The same applies to the Formulations transverse axis, longitudinal axis and vertical axis (vertical axis). These terms therefore refer to the Battery module.

[0018] Typically, the HV battery is oriented in the vehicle in such a way that the transverse direction of a battery module in The longitudinal direction of the vehicle (x-direction) is in the direction of travel of the vehicle. thus in the vehicle's transverse direction (y-direction), i.e. perpendicular to the vehicle's longitudinal direction in the horizontal plane. The vertical direction corresponds to the vehicle’s vertical direction (z-direction), which is perpendicular to the The wording refers to both the longitudinal direction of the vehicle and the transverse direction of the vehicle in the vertical direction. The vehicle’s longitudinal axis, transverse axis and vertical axis refer to the corresponding axes in Vehicle longitudinal direction, vehicle transverse direction and vehicle vertical direction.

[0019] The movement of the battery module is thus controlled by the guide element, which is in engagement with the slotted guide. Consequently, the battery module can only be used in the gate and through the first and second sections of the gate The guide element preferably has a thickening which is It is dimensioned so that it can not only slide the backdrop, but is therefore wider than the opening of the backdrop, so that movement of the battery module in its longitudinal direction can also be prevented.

[0020] By specifying the movement trajectory through the backdrop, it is possible to only control the movement to allow modifications to the battery module that do not cause damage to other battery modules and in particular to Sealing elements between the battery modules. This allows for easier and safer removal Once the battery module has completed its movement trajectory, the base plate is secured from the battery frame so that the device with the battery module is lifted further in the vertical direction.

[0021] In a preferred embodiment of the invention, an extension of the first section in the direction the vertical axis of a maximum possible deflection of a sealing element, which is used to seal a cooling line between the first battery module and an adjacent second battery module, in the vertical direction. Such sealing elements must, as described above, be able to accommodate certain positional tolerances of the battery modules in They are therefore designed to be flexible, so that a limited movement of the first battery module relative to the second adjacent battery module in the vertical direction. Lifting the battery module by this limited distance, which is determined by the first section and its extension in vertical direction, the battery module can be lifted by the underrun protection located below it The battery module can then be moved in its transverse direction to separate it from the sealing element. An immediate transverse movement would have a high risk of damaging the base of the first Battery module, especially the underrun protection, or due to the high shear stress at least of the The sealing contours arranged between the underrun protection and the battery module result in a This embodiment minimizes the risk of damage and further improves the device.This text has been copied by the DPMA from the original sources. It does not contain any drawings. The tables and formulas may be of unsatisfactory quality.

[0022] In a further advantageous embodiment of the invention, an extension of the second section in Direction of the transverse axis in such a way that sealing contours which are formed by a movement in the direction of the transverse axis absorb the shear forces between the battery module and the underrun protection and therefore are not damaged Such an embodiment also limits the movement of the battery module in such a way that no Damage to other elements may occur. In this case, the maximum movement in the transverse direction of the battery module is limited by the second section. Thus, this embodiment also contributes to further improvement of the device according to the invention, in which the risk of damage during disassembly of the first Battery module can be reduced.

[0023] Another advantageous embodiment of the invention is one in which an entire extension of the first section and the second section in the direction of the transverse axis at least half the length of a base body of a Sealing element which is used to seal a cooling channel between the first battery module and an adjacent second battery module. The base body is the element of the sealing element, which protrudes from one cooling channel of the first battery module into that of the second battery module in order to thus To connect cooling channels to form a cooling channel. The base body is usually appropriate sealing rings and attached to the cooling channels of the two battery modules. In this way, It must be ensured that the first battery module is first moved far enough in the transverse direction before it is vertical direction to prevent damage to the sealing element or adjacent battery modules Consequently, the device can be further improved by this embodiment.

[0024] In a further preferred embodiment of the invention, the device comprises two base plates and two Guide elements which are designed to be mounted on the opposite end faces of the first By using two opposing base plates With guide elements and corresponding links provided in the base plates, a synchronous movement along the movement trajectory specified by the scenes. Thus, the movement accuracy during the Disassembly of the first battery module can be further increased and the device can be further improved.

[0025] Furthermore, an embodiment of the invention with two base plates is advantageous, in which the device Support frame which is designed to connect the two base plates together and consequently from one base plate to the other. In this way, the handling of the device can be improved and the Positioning of the two base plates can be simplified.

[0026] In a further advantageous embodiment of the invention, the first section of the gate extends exclusively in the vertical direction and the second section of the backdrop exclusively in the transverse direction. Movement trajectory is divided into two sections, with the first movement in the direction of the vertical axis and This is done in a transverse direction. Therefore, the battery module is lifted first to transfer the shearing load to the Sealing contours on the sub The defined movement The sealing element can then be separated from the first battery module along the second section of the gate, so that The entire battery module can then be lifted out of the vehicle in a vertical direction.

[0027] Preferably, the gate in the device according to the invention further comprises a third section, which extends at least partially, in particular exclusively, in the direction of the vertical axis. In this way, the This text has been copied by the DPMA from the original sources. It does not contain any drawings. The tables and formulas may be of unsatisfactory quality. Battery module continues vertically on a fixed movement trajectory until reaching an upper Dead center in the third section and, for example, rocking or similar unwanted lateral Movements are prevented.

[0028] Preferably, the first section merges into the second section and the second section merges into the third Section above. They are thus arranged in such a way that they are connected to each other and the guide element, after which Passing through the first section into the second section and then into the third section. Particularly preferred is an embodiment of the invention in which the sections are formed in a step shape The sections are thus perpendicular to each other, so that a right-angled arrangement of the first, second and third sections of the backdrop. This ensures a simple movement trajectory, which allows the best possible disassembly of the battery module.

[0029] In a further advantageous embodiment of the invention, the base plate has attachment points which are designed to serve as attachment points for a crane. The crane is designed in particular to move the battery module vertically. This allows the battery module to be lifted onto the attachment points with the crane and a stable and secure attachment is ensured when the first battery module is the backdrop has passed through the movement trajectory specified, the attachment to the battery frame has been released and now the device according to the invention is raised further in the z-direction together with the first battery module.

[0030] The method according to the invention for disassembling a first battery module of an HV battery in a Vehicle from a battery frame with an underrun protection arranged on it and under the first battery module The installation of the sealing contours comprises the following steps. The first step is to fix at least one base plate with a link, which has at least a first section, which is at least partially in the direction of a vertical axis, and a second section which extends at least partially in the direction of a transverse axis, to the battery frame by at least one fastening element such that the Base plate is arranged on a front surface of the first battery module. The sections of the gate are into each other. In the context of the application, the end faces are to be understood as the end faces of the battery module, which point in the longitudinal direction. A guide element is then attached to the end face where the base plate is attached, wherein the guide element and the base plate are arranged such that the Guide element is arranged in a bottom dead center of the first section of the link and engages in the link. The first battery module is then lifted at least partially in the vertical direction until the guide element has passed the first section. Subsequently, the first battery module is at least partially moved towards a transverse direction until the guide element has passed through the second section. Once the battery module has the movement trajectory specified by the backdrop, the at least one fastening element is The battery frame is then removed again. The battery module can then be removed together with the device according to the invention upwards, i.e. in the vertical direction, completely lifted out of the vehicle.

[0031] Preferably, the gate has a third section which extends at least partially in the vertical direction and the first battery module is further lifted at least partially in the vertical direction until the guide element has passed the third section. In this way, even when lifting the battery module from the vehicle, a fixed movement trajectory must be ensured and a unwanted swinging or rocking of the battery module can be prevented. In such an embodiment, Accordingly, the process step of releasing the fastening element from the battery frame only after the Passing through the guide element through the third section.

[0032] In the following, advantageous aspects and embodiments of the invention are described with reference to the explained in more detail in the attached figures. They show:This text has been copied by the DPMA from the original sources. It does not contain any drawings. The tables and formulas may be of unsatisfactory quality. Fig. 1 shows a schematic illustration of the device according to the invention in a first embodiment. Fig. 2a shows a schematic detailed view of a sealing element 6 between a first Battery module 21 and a second battery module 22 according to Fig. 1 in a first stage Fig. 2b shows the schematic detailed view from Fig. 2a of the sealing element 6 in a second stage

[0033] For the replacement of battery modules in vehicle workshops, the HV battery is removed from the vehicle and placed on a suitable work table. If there is a lid on the top, this lid is placed together with Sealing removed to ensure accessibility of the battery modules. Cable trays, HV busbars, Control units and other peripherals are also removed. The battery modules and their weight are now on the bottom of the battery and must be lifted with a crane for further disassembly of the HV battery. The disassembly state described in this section is shown in Fig. 1.

[0034] Fig. 1 shows a schematic illustration of the device according to the invention in a first embodiment. The HV battery 100 of a vehicle is formed from several battery modules 21, 22, 23. Shown here is a first Battery module 21, a second battery module 22 and a third battery module 23. The battery modules 21, 22, 23 are in Vehicle longitudinal direction x arranged one behind the other, wherein they have end faces 12 which are directed in the direction of Vehicle transverse axis y. In the embodiment shown, the transverse axis / transverse direction corresponds to the Battery modules 21, 22, 23 of the vehicle longitudinal axis / vehicle longitudinal direction x, the longitudinal axis / longitudinal direction of the Battery modules 21, 22, 23 of the vehicle transverse axis / vehicle transverse direction y and the vertical axis / vertical direction of the Battery modules 21, 22, 23 of the vehicle vertical axis / vehicle vertical direction e.g.

[0035] The battery modules 21, 22, 23 are further arranged on a battery frame 3, which is secured by corresponding Longitudinal members 31, which are located in the area of ​​the side sills of the vehicle. Furthermore, a Underrun protection 2 is provided, which is attached to the battery frame 3 and serves as Between the battery modules 21, 22, 23 and the underrun protection 2 there are also sealing contours 4 These are often designed as foam seals according to the state of the art and must therefore not exposed to large shear forces to avoid damage. Such shear forces would occur if the first battery module 21 to be dismantled is moved in the direction of the vehicle's longitudinal axis x in the state shown and thus the entire weight of the battery module would still be on the sealing contours 4.

[0036] Furthermore, the battery modules 21, 22, 23 are connected to one another via sealing elements 6. The sealing elements 6 are explained in more detail in the detailed views of Fig. 2a and Fig. 2b. Fig. 2a shows the sealing element 6 in the initial position, as shown in Fig. 1. It consists of a base body 7, which is usually Pipe segment is formed and usually vulcanized sealing rings 8 made of elastomer, which the base body 7 on both sides of a cooling channel 9 in the adjacent battery modules 21, 22. Only the Sealing rings 8 the cooling channel 9. In the state shown in Fig. 2a, the sealing element 6 thus creates a fluidic Connection between the cooling channels 9 of the adjacent battery modules 21, 22 is realized, wherein the cooling channel 9 in the Essentially straight.This text has been copied by the DPMA from the original sources. It does not contain any drawings. The tables and formulas may be of unsatisfactory quality.

[0037] In order to prevent damage to the sealing element 6 when removing the first battery module 21 in To prevent the vertical direction z of the vehicle, the first battery module 21 must first be in its transverse direction, i.e. in Vehicle longitudinal direction x, to separate it from the sealing element 6. However, the movement in x- Direction in the state shown in Fig. 1 as already mentioned may damage the sealing contours 4.

[0038] To prevent this, the device according to the invention for disassembling the first battery module 21 The device consists of two base plates 15, which are mounted on opposite end faces 12 of the first battery module 21 are arranged plane-parallel to the end faces 12. They are thereby Fastening elements 10 are detachably attached to the battery frame 3. The fastening elements 10 are suitable fastening devices, such as screws, screw clamps, suction cups or similar on the battery frame 3 The two base plates 15 are connected to each other by a support frame 18, wherein the support frame 18 above the first battery module 21. A guide 14 is provided in each of the base plates 15. This is simple recess in the base plates 15. The link 14 has a first section A1, which in the vertical direction, a second section A2, which extends in the transverse direction (vehicle longitudinal direction x), and a third section A3, which again extends in the vertical direction. All sections A1, A2, A3 have the same constant width of the recess.

[0039] Furthermore, a guide element 13 is provided on each side, which is fixed to the corresponding end face 12 at a defined position and engages in the respective link 14. The guide element 13 can be used as a simple Bol zen or screw and preferably has a thickening at the end, the diameter or width of which is larger than the width of the backdrop 14 and therefore does not fit through the backdrop 14. The base plates 15 and the Guide elements 13 are provided in such a way that the guide elements 13 in their respective slotted guide 14 are bottom dead center 17.

[0040] The first battery module 21 is further connected to a crane 16 via a corresponding receptacle 162, which can be moved in the x-direction and whose main direction of movement is in the z-direction, so that it first battery module 21 can be lifted out of the vehicle in the vehicle vertical direction z.

[0041] The invention makes use of the property of the sealing element 6, according to which it is able to compensate for certain positional tolerances of the battery modules 21, 22, 23. Thus, it is able to compensate for a small offset in z-direction without being damaged. This state is shown in Fig. 2b. In comparison to Fig. 2a In the state shown, the first battery module 21 is raised further than the second battery module 22. This the cooling channel experiences a slight bend. It is important that a maximum offset in the z-direction is not exceeded to prevent damage to the sealing element 6.

[0042] This offset is limited by the first section A1. If the first battery module 21 is lifted by the crane 16 raised, the movement of the first battery module 21 is guided by the guide element 13 in the link 14, wherein the guide element 13 moves upwards in the plane of the drawing within the first section A1. The first section A1 prevents any movement in the x-direction and also limits the maximum offset in the z-direction. If the crane 16 makes too large a movement in the z-direction, the guide element 13 hits the link 14 and thus prevents further relative movement in the z-direction between the first battery module 21 and the second battery module 22. The length or extension of the first section A1 is thus preferably in Dependence on the offset was selected which does not lead to damage to the sealing element 6.This text has been copied by the DPMA from the original sources. It does not contain any drawings. The tables and formulas may be of unsatisfactory quality.

[0043] In this position, the weight of the first battery module 21 is thus absorbed by the sealing contours 4 taken, so that a movement in the x-direction is then possible without a large shear stress on the sealing contours 4. Consequently, the crane 16 is then moved in the x-direction, whereby the Guide element 13 is moved along the second horizontal section A2 of the link 14. The extension of the second section A2 is preferably at least half the length of the base body 7 of the sealing element 6, so that it is ensured that the base body 7 is pulled out of the cooling channel 9 of the second battery module 21.

[0044] If the second section A2 has been passed through and the corresponding stop in the x-direction of the guide element 13 reached, the battery module 21 is moved again in the z-direction by the crane 16 until the guide element 13 rests on a top dead center 24 in the third section A3. The third section A3 prevents the first Battery module 21 performs unwanted pendulum or rocking movements, so that damage to other elements can be prevented. Due to the stronger (thicker) ends of the guide elements 13, which are not Link 14 can be guided, a movement in the γ-direction is also excluded.

[0045] Subsequently, the device according to the invention is secured via attachment points 161 provided in the base plates 15 connected to the crane and the fastening means 10 for fastening the device to the battery frame 3 are loosened. Subsequently, the first battery module 21 together with the device according to the invention is removed from the vehicle in the z-direction raised.

[0046] The device can thus be referred to as a sliding gate for the first battery module 21, which Movement trajectory of the battery module 21 is defined and the degrees of freedom during crane operation are restricted in such a way that Damage to other elements of the HV battery 100 can be prevented.

[0047] The device according to the invention offers the possibility of using a battery module despite cooling The sealing element can be removed and installed individually from the HV battery system without causing any damage. The individual movement phases allow for degrees of freedom that are precisely tailored to the design of the HV battery (e.g. Movement range of the sealing element due to its tolerance compensation function, shear strength of the foam sealing material on the underrun protection). This makes it possible to replace the cell module with the relatively inaccurate or This makes it possible to use a difficult-to-meter workshop crane. Furthermore, the risk of incorrect operation is greatly reduced.

[0048] It should be noted at this point that the invention is also conceivable with regard to battery modules, which are installed in the vehicle in a different orientation than shown here and not on the Orientation limited To do this, the orientation of the second section must be adjusted to the orientation of the end faces of the Battery modules can be adapted. For example, if the battery modules are oriented so that their end faces are in vehicle's longitudinal direction, the second section of the gate must be in the γ-direction and not in the x- point the way.
