[0002] Storage housings for electrical energy storage devices are already well known in the general state of the art. Protective elements, in particular protective plates, for armored vehicles are also known. An electrical energy storage device located in the underbody area of ​​the armored vehicle can be protected from explosions, bullets, and / or similar damage by means of the protective element.

[0005] In addition, an underbody unit for stiffening a motor vehicle body, in particular between a front axle and a rear axle, is known from DE 10 2014 108 160 A1.

[0006] The object of the invention is to provide a storage housing for an electrical energy storage device of an electrically driven special protection vehicle, an arrangement of an electrical energy storage device in an underbody region of an electrically driven special protection vehicle and a method for producing a storage housing for an electrical energy storage device of an electrically driven special protection vehicle, so that security against damage and deformation of the electrical energy storage device can be particularly increased in a particularly low-cost manner.

[0007] This object is achieved according to the invention by a storage housing for an electrical energy storage device of an electrically driven special protection vehicle having the features of patent claim 1, an arrangement of an electrical energy storage device in an underbody region of an electrically driven special protection vehicle having the features of patent claim 6, and by a method for producing a storage housing having at least one profile for an electrical energy storage device of an electrically driven special protection vehicle having the features of patent claim 10. Advantageous embodiments of the invention are the subject of the dependent patent claims and the description.

[0008] A first aspect of the invention relates to a storage housing for an electrical energy storage device of an electrically powered special-armored vehicle. The special-armored vehicle is designed, for example, as a passenger car.

[0009] A special protection vehicle can be understood, in particular, as a special protection vehicle. The special protection vehicle preferably has at least one integrated armor plating to protect the occupants or cargo of the special protection vehicle from external attacks. The special protection vehicle can therefore also be referred to as a security vehicle.

[0010] The fact that the special protection vehicle is electrically driven can be understood in particular to mean that the special protection vehicle has at least one electric machine by means of which the special protection vehicle can be driven electrically, for example purely electrically. Thus, the special protection vehicle is, for example, a battery-electric vehicle or a hybrid vehicle. In other words, the special protection vehicle is designed, for example, as a battery-electric vehicle or a hybrid vehicle. In particular, if the special protection vehicle is designed as a battery-electric vehicle, the special protection vehicle can be understood in particular as a fully electric vehicle.

[0011] Preferably, the electrical machine can be supplied with electrical energy, in particular stored or chemically bound in the electrical energy storage device, by means of the electrical energy storage device in order to drive the special protection vehicle electrically, in particular purely electrically. In other words, the electrical energy storage device is preferably designed as an electrical traction storage device, in particular as a traction battery. The electrical energy storage device is designed, for example, as a battery or an accumulator.

[0012] In order to achieve particularly high electrical power for electrically, in particular purely electrically, driving the special armored vehicle, the electrical energy storage device can have an electrical voltage, in particular an electrical operating or nominal voltage, which is preferably greater than 50 volts, in particular above 60 volts, and preferably amounts to several hundred volts. Accordingly, the electrical energy storage device is preferably designed as a high-voltage component. In other words, the electrical energy storage device is designed as a high-voltage storage device, in particular as a high-voltage battery.

[0013] The storage housing has at least one connection area, via which the electrical energy storage device is to be or is to be held in an underbody area of ​​the special armored vehicle. In other words, the storage housing, in particular the electrical energy storage device, is to be or is to be arranged in the underbody area.

[0014] The underbody area of ​​the special protection vehicle can in particular be referred to as the underfloor area. The underbody area can be understood to mean, in relation to a vertical direction of the special protection vehicle, in particular a lower area, of the special protection vehicle. The underbody area or the area is arranged, for example, in the vertical direction of the vehicle under a floor element, for example a main floor, of a body of the special protection vehicle. The body is preferably designed as a self-supporting body. The body preferably delimits an interior of the special protection vehicle at least partially, in particular predominantly or completely, for example at least indirectly or directly. The interior, which can in particular be referred to as the vehicle interior, can in particular be understood to mean a passenger compartment or a passenger cell.Preferably, the electrical energy storage device is arranged vertically beneath the floor element. In other words, the electrical energy storage device is designed as an underfloor storage device, in particular as an underfloor battery.

[0015] The storage housing has at least one receiving space that is at least partially, in particular predominantly or completely, for example directly, delimited by at least one housing element of the storage housing. This means that the receiving space is at least partially formed by the housing element. In other words, the receiving space is at least partially, in particular predominantly or completely, surrounded by the storage housing, in particular by the housing element of the storage housing. At least one storage element, in particular at least one storage cell, of the electrical energy storage device is to be arranged or is arranged in the receiving space. This means that the at least one storage element is arranged within the storage housing. In other words, the receiving space is designed to receive or arrange the at least one storage element.Preferably, a plurality of storage elements, in particular storage cells, are to be arranged or are arranged within the storage housing or in the receiving space.

[0016] The storage element can be understood, in particular, as an electrical storage element. The storage element is preferably designed as a storage cell. The electrical energy storage device preferably comprises a plurality of modules, in particular cell modules, each of which comprises a plurality of storage elements, in particular storage cells. The cell modules are preferably arranged or are arranged in the receiving space or within the storage housing.

[0017] The storage housing has at least one profile, in particular an extruded profile, for example an extruded aluminum profile. For example, it is thus provided that the storage housing, in particular at least one housing part of the storage housing, is or will be produced by extrusion, in particular aluminum extrusion. The profile has at least one cavity that is at least partially, in particular predominantly or completely, delimited or formed by at least one wall of the profile. This means that the cavity, which extends in particular within the profile, is at least partially, in particular predominantly or completely, surrounded by the wall or covered by the wall. In other words, the profile or at least the housing part is designed as a hollow profile. The cavity is preferably spaced from the receiving space.

[0018] Preferably, the extruded profile, in particular having the cavity, is designed as a deformation element for dissipating collision energy, for example in the event of a side collision of the special armored vehicle. This means that a mechanical load, referred to in particular as collision energy, acting on the special armored vehicle, in particular the storage housing, in the event of an accident, for example in a side collision, can be dissipated or is dissipated by means of the extruded profile, in particular by preferably plastically deforming the extruded profile, in particular the cavity. In other words, the extruded profile is designed as a crash profile, in particular as a high-voltage storage crash profile. This can significantly increase the safety, in particular the passive safety, of the special armored vehicle.

[0019] In order to be able to particularly increase security against damage and deformation of the electrical energy storage device, in particular of the receiving space and / or of the at least one storage element, in a particularly low-cost manner, it is provided that at least one protective element formed separately from the wall, in particular separately from the profile, is arranged or received in the cavity. In other words, the protective element extends at least partially, in particular predominantly or completely, into the cavity, i.e. within the profile. This means that the protective element is covered at least partially, in particular predominantly or completely, for example in the vehicle vertical direction and / or in the vehicle transverse direction of the special armored vehicle, by the wall, in particular by the profile.By means of the protective element, the electrical energy storage device, in particular the receiving space and / or the storage cell, is protected or can be protected at least against explosions, bombardment, and / or the like. In other words, the protective element is designed to protect the receiving space of the electrical energy storage device, which is arranged behind it, in particular further inward than the protective element with respect to the vehicle's transverse direction.

[0020] The term "blast" can be understood in particular as an explosion or detonation, for example, caused by an explosive. For example, the blasting is an explosion caused or induced by a hand grenade. Thus, the special armored vehicle, in particular the underbody area of ​​the special armored vehicle, preferably the electrical energy storage unit, in particular the receiving space, can be protected by the protective element from a hand grenade detonating in the area of ​​the special armored vehicle. The protective element is understood to mean an armored protective element. The protective element is preferably formed at least partially, in particular predominantly or entirely, from armored steel.

[0021] Thus, the integrated armor of the special protection vehicle, for example, is at least partially formed by the protective element. The special protection vehicle can have additional protective elements, particularly armor elements, formed separately from the protective element. The special protection vehicle can therefore also be referred to as an armored vehicle.

[0022] The invention is based in particular on the following findings and considerations: By means of the protective element, the profile, which or its wall is preferably not armored, can be reinforced or armored, so that the electrical energy storage device, in particular the receiving space and / or the storage cell, can be protected from explosives, shelling, and / or the like. In particular, the electrical energy storage device can be protected from lateral shelling relative to the transverse direction of the vehicle. The armored vehicle can thus be particularly well protected against external attacks.The protective element allows the profile, in particular one that is structurally identical or can be used across different construction variants, to be used across all construction variants in the electrically powered special armored vehicle and in another vehicle, which is designed, for example, as a combustion engine-powered special armored vehicle or as a non-armored vehicle. The number of identical parts can therefore be increased significantly across multiple model series. This allows the manufacturing costs for the electrically powered special armored vehicle to be kept particularly low. The protective element can therefore, for example, only be arranged in the cavity of the profile if the vehicle or special armored vehicle featuring the profile requires armor plating in the underbody area, in particular for the electrical energy storage device.In particular, extensive structural modifications to the storage housing of the electrically powered special armored vehicle can be avoided. Overall, it can be seen that the protective element can ensure protection, particularly ballistic protection, for the electrical energy storage device in electrified security vehicles. Because the protective element is or will be arranged in the cavity, the protective element can be understood in particular as an insert, in particular a protective insert, which can be referred to, for example, as a ballistic insert.

[0023] In particular, the protective element allows the storage housing, in particular the profile, to be armored or reinforced in a particularly lightweight manner, since the protective element can, for example, provide targeted and local armoring or reinforcement for the profile, while, for example, remaining wall thicknesses, in particular the thickness of the wall, can be kept the same, thus eliminating the need for an increase. This allows the weight of the storage housing, in particular of the armored vehicle, to be kept particularly low.

[0024] Preferably, the protective element is held, in particular in the cavity, for example, in particular directly, on the wall. This means that the protective element can be fixed in the cavity, i.e., within the cavity, for example, can be fastened to the wall. Thus, an integration of at least one, in particular ballistic, protective component in the form of the protective element on the storage housing can be realized, wherein the protective element is fastened, in particular, to a storage housing structure of the storage housing. In other words, a ballistic insert for protecting the high-voltage storage device can be fastened to the storage housing and / or to the storage structure.

[0025] In a further embodiment, the protective element extends at an angle to the wall. In other words, the protective element protrudes at an angle from the wall. As a result, the protective element can create a deflection angle for projectiles and / or fragments that impact the protective element, in particular directly. Thus, the projectiles and / or fragments impacting the protective element can be deflected by the protective element and, in particular, deflected away from the armored vehicle, preferably from the electrical energy storage device, in particular from the receiving space. This significantly increases the safety against damage and deformation of the electrical energy storage device.

[0026] In particular, the security of the special protection vehicle against external attacks can be increased.

[0027] For example, it is provided that the protective element extends obliquely to the vertical axis of the special armored vehicle and / or obliquely to the transverse axis of the special armored vehicle. In other words, the protective element forms an angle with a vertical axis and / or a transverse axis of the special armored vehicle that is greater than 0 degrees and less than 90 degrees. This allows the projectiles and / or fragments to be deflected particularly effectively by the protective element.

[0028] In a further embodiment, it is provided that the protective element extends in the longitudinal direction of the special armored vehicle. In other words, a main direction of extension of the protective element runs at least substantially in the longitudinal direction of the vehicle. As a result, the electrical energy store, in particular the receiving space, can be particularly well covered from the outside by the protective element along the longitudinal direction of the vehicle in the transverse direction of the vehicle, whereby the electrical energy store, in particular the receiving space, can be particularly well protected. Preferably, the protective element extends at least over a complete length of the receiving space, in particular of the electrical energy store, for example the profile, extending in the longitudinal direction of the vehicle. Preferably, an axial direction of the cavity runs at least substantially in the longitudinal direction of the vehicle.

[0029] In a further embodiment, it is provided that a cross-sectional area, in particular a cross section, of the cavity is subdivided or divided by the protective element into two equally sized cross-sectional area parts. This means that the cross-sectional area of ​​the cavity, in particular the cross section of the cavity, is subdivided or divided by the protective element into a first cross-sectional area and a second cross-sectional area, wherein the first and second cross-sectional areas are of equal size. In other words, the cavity is divided by the protective element into two equally sized cavity parts. This allows the storage housing, in particular the profile, to be particularly well reinforced. Furthermore, a particularly good deflection angle for deflecting the fragments and / or projectiles impacting the protective element can be achieved.The cross-section extends, for example, in a plane spanned, in particular imaginary, by the vehicle's vertical axis and the vehicle's transverse axis.

[0030] In a further embodiment, the protective element, in particular for producing the storage housing, is or will be inserted into the cavity, for example, in the longitudinal direction of the vehicle. In other words, the protective element is designed as a reinforcement, in particular for the profile or the storage housing, inserted or inserted into the profile or the cavity. This allows the storage housing, in particular for the armored vehicle, to be manufactured with particularly low effort.

[0031] Preferably, the protective element is movable or can be moved relative to the wall in a mounting direction in order to arrange the protective element, which is initially located outside the cavity, in the cavity, in particular to insert it into the cavity. The mounting direction preferably runs at least substantially in the longitudinal direction of the vehicle. Preferably, the mounting direction runs parallel to the axial direction of the cavity.

[0032] A second aspect of the invention relates to an arrangement of at least one electrical energy storage device in an underbody area of ​​an electrically powered special-armored vehicle. The special-armored vehicle is designed, for example, as a passenger car. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa.

[0033] The electrical energy storage device has at least one storage housing, which at least partially, in particular predominantly or completely, for example directly, delimits or forms at least one receiving space. In other words, the receiving space is at least partially, in particular predominantly or completely, surrounded by the storage housing, in particular by at least one housing element of the storage housing. At least one storage element, in particular at least one storage cell, of the electrical energy storage device is arranged or accommodated in the receiving space. This means that the at least one storage element is arranged within the storage housing. In other words, the receiving space is designed to accommodate or arrange the at least one storage element.Preferably, a plurality of storage elements, in particular storage cells, are arranged or accommodated within the storage housing or in the receiving space. The storage element can be understood, in particular, as an electrical storage element. The storage element is preferably designed as a storage cell. Preferably, the electrical energy storage device comprises a plurality of modules, in particular cell modules, each of which comprises a plurality of storage elements, in particular storage cells. The cell modules are preferably arranged in the receiving space or within the storage housing.

[0034] The storage housing has at least one profile, in particular an extruded profile, which has at least one cavity which is at least partially, in particular predominantly or completely, delimited by at least one wall of the profile.

[0035] In order to be able to particularly increase security against damage and deformation of the electrical energy storage device, in particular of the receiving space and / or of the at least one storage element, in a particularly low-cost manner, it is provided that at least one armored protective element formed separately from the wall, in particular separately from the profile, is arranged or received in the cavity.

[0036] In a further embodiment, the profile extends outward in the transverse direction of the vehicle to at least one side sill of the armored vehicle. This provides particularly good protection for the armored vehicle against explosives, gunfire, and / or similar impacts, as well as in the event of an accident.

[0037] Preferably, the profile is arranged at least partially further down in the vehicle's vertical direction than the side sill. This means that the profile extends at least partially further down in the vehicle's vertical direction than the side sill. In other words, the profile is covered, in particular directly, at least partially upward in the vehicle's vertical direction by at least one of the side sills. As a result, the special armored vehicle can be protected from explosives, ballistic attacks, and / or the like in the area of ​​the profile by the protective element, and in the area of ​​the side sill, for example, by a further protective element, in particular one formed separately from the protective element.

[0038] In a further embodiment, it is provided that the profile has at least one connection area via which the electrical energy storage device is held, in particular at least indirectly or directly, to a body, for example to at least one body component of the body, in particular to at least one of the side sills, of the special protection vehicle. In other words, the electrical energy storage device is fastened, via the connection area of ​​the profile, at least indirectly, in particular directly, to the body, for example to the body component, in particular to the side sill. This allows the electrical energy storage device to be fastened particularly securely in the special protection vehicle. In particular, the electrical energy storage device is held to the body via the connection area via the side sill, i.e. via the side sill.For example, the electrical energy storage device is screwed to the body via the connection area, in particular via the side sill. In a further embodiment, it is provided that the electrical energy storage device is covered at least partially, in particular predominantly or completely, downwards in the vertical direction of the vehicle by a protective plate, whereby the electrical energy storage device is or can be protected at least from explosive attack by means of the protective plate. This means that the protective plate is arranged at least partially, in particular predominantly or completely, below the electrical energy storage device, in particular below the storage housing, in the vertical direction of the vehicle. The protective plate and the storage housing, in particular the electrical energy storage device, are designed separately from one another.The fact that the electrical energy storage device is protected from explosive attack by the protective plate can be understood in particular to mean that the protective plate is designed to protect the electrical energy storage device located behind it, particularly above the protective plate in relation to the vehicle's vertical direction. This can significantly increase the safety against damage and deformation of the electrical energy storage device. In particular, it can significantly increase the safety against external attacks from the special armored vehicle.

[0039] In a further embodiment, it is provided that the protective plate has at least one fastening area, via which the protective plate is held, in particular at least indirectly or directly, to the body, for example to the body component, in particular to at least one of the side sills, of the special armored vehicle. In other words, the protective plate is fastened via the fastening area, in particular at least indirectly or directly, to the body, for example to the body component, in particular to at least one of the side sills. In particular, the protective plate is held to the body via the fastening area via the side sill, i.e. with the mediation of the side sill. For example, the protective plate is screwed to the body via the fastening area, in particular via the side sill.

[0040] In a further embodiment, the protective element is arranged further outward in the transverse direction of the vehicle than the fastening area. In other words, the protective element extends further outward in the transverse direction of the vehicle than the fastening area. As a result, the fastening area, in particular at least one screw connection for fastening the protective element to the body or the side sill, can be particularly well protected by the protective element, in particular against explosives, bullets, and / or the like. This means that the protective plate can be attached to the body particularly securely. This significantly increases the security of the special armored vehicle against external attacks.

[0041] In order to be able to particularly increase the protection against damage and deformation of the electrical energy storage device and to be able to keep the manufacturing costs of the special armored vehicle particularly low, it is provided, for example, that the protective plate, with respect to the body, in particular the body component, and the electrical energy storage device, is held exclusively, in particular at least indirectly or directly, on the body, in particular on the body component and / or the side sill. This means that the protective plate is not held or fastened to the electrical energy storage device, in particular not to the storage housing, and in particular is not held or fastened to the body via the electrical energy storage device, in particular via the storage housing.In other words, the protective plate is held on the body in a manner decoupled from a storage housing attachment, by means of which the electrical energy storage device, in particular the storage housing, is held in the underbody area, in particular on the body. In other words, the protective plate is held or attached to the body independently of the electrical energy storage device.

[0042] This allows the electrical energy storage device, in particular the storage housing, and / or the connection of the electrical energy storage device to the body to be used across all construction variants in the special armored vehicle and in another non-armored vehicle. This allows the manufacturing effort, in particular the manufacturing costs, of the special armored vehicle to be kept particularly low.

[0043] A third aspect of the invention relates to a method for producing a storage housing comprising at least one profile, in particular an extruded profile, in particular according to the first aspect of the invention, for an electrical energy storage device of an electrically powered special armored vehicle. Advantages and advantageous embodiments of the first and second aspects of the invention are to be regarded as advantages and advantageous embodiments of the third aspect of the invention, and vice versa.

[0044] In order to be able to particularly increase security against damage and deformation of the electrical energy storage device in a particularly low-cost manner, it is provided that in at least one cavity which is at least partially, in particular predominantly or completely, delimited or formed by at least one wall of the profile, at least one armored protective element formed separately from the wall, in particular the profile, is arranged, in particular inserted, by means of which the electrical energy storage device can be or is protected against blasting, shelling and / or the like.

[0045] For example, the protective element is moved relative to the wall in an assembly direction for placement in the receiving space. The assembly direction preferably runs in the longitudinal direction of the special armored vehicle. The protective element, arranged in particular in the cavity, is preferably attached, for example at least indirectly or directly, to the profile, in particular to the wall.

[0046] Further features of the invention emerge from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respective specified combination, but also in other combinations or on their own.

[0047] The invention will now be explained in more detail using a preferred embodiment and with reference to the drawings. They show: Fig. 1 is a schematic perspective view of an arrangement according to the invention; Fig. 2 a schematic and perspective partial sectional view of an arrangement according to the invention; Fig. 3 a schematic partial sectional view of an arrangement according to the invention; Fig. 4 a schematic and perspective further partial sectional view of an arrangement according to the invention; Fig. 5 a schematic and perspective partial sectional view of an arrangement according to the invention in a first sectional plane; Fig. 6 a schematic and perspective partial sectional view of an arrangement according to the invention in a second sectional plane; Fig. 7 is a schematic plan view of an arrangement according to the invention; and Fig. 8 a schematic further partial sectional view of an arrangement according to the invention.

[0048] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0049] Fig. Figure 1 shows a schematic perspective view of an arrangement 1 of a protective plate 2 in an underbody area 3 of an electrically driven special protection vehicle 4, viewed diagonally from below. In particular, Fig. 1 shows a schematic and perspective partial view of the special protection vehicle 4. Fig. 2 shows the arrangement 1, in particular the special protection vehicle 4, in a schematic and perspective partial sectional view.

[0050] The special protection vehicle 4 has a, in particular self-supporting, body 5, which preferably at least partially, in particular predominantly or completely, delimits or forms an interior 6 of the special protection vehicle 4. In the exemplary embodiment, the body 5 has at least one floor element 7, which is designed, for example, as the main floor of the body 5. The floor element 7 delimits the interior 6 in the vehicle vertical direction 8 of the special protection vehicle 4 at least partially, in particular predominantly or completely, downwards. The body 5 preferably has two side walls 9. This means that the body 5 has a first side wall 9 and a second side wall spaced from the first side wall 9 in the vehicle transverse direction 10. The respective side wall can in particular be referred to as a respective side frame.Preferably, the respective side wall 9 delimits the interior space 6 in the vehicle transverse direction 10 at least partially, in particular predominantly or completely.

[0051] In the exemplary embodiment, the body 5 has two side sills 11. This means that the body 5 has a first side sill 11 and a second side sill spaced apart from the first side sill 11 in the vehicle transverse direction 10. For example, the respective side sill 11 adjoins the respective side wall 9, in particular a respective outer part 12 of the respective side wall 9, at least indirectly, in particular directly, downwards in the vehicle vertical direction 8. The respective side sill 11 can be part of the respective side wall 9, or the respective side sill 11 can be formed separately from the respective side wall 9.

[0052] For example, the respective side wall 9 has at least one respective inner part 13, in particular formed separately from the respective outer part 12, by means of which the special armored vehicle 4, in particular the interior 6, is or can be protected, preferably against explosions, shelling, and / or the like. Thus, the inner part 13 is formed, for example, from armored steel.

[0053] Fig. Figure 3 shows the arrangement 1 in a schematic partial sectional view. The special armored vehicle 4 has at least one electrical energy storage device 14, which is arranged in the underbody area 3, in particular in the vertical direction 8 of the vehicle under the floor element 7.

[0054] Thus, in Fig. 1 to 3 each show a respective arrangement of the electrical energy storage device 14 in the underbody area 3 of the electrically driven special protection vehicle 4.

[0055] The electrical energy storage device 14 has at least one storage housing 15, which has at least one connection area 16, via which the electrical energy storage device 14 is held in the underbody area 3, for example, at least indirectly or directly on the body 5. The connection area 16 can be understood in particular as a fastening area of ​​the electrical energy storage device 14, in particular of the storage housing 15. In the exemplary embodiment, the electrical energy storage device 14, in particular the storage housing 15, is screwed to the body 5, for example via the connection area 16.

[0056] The electrical energy storage device 14 is at least partially, in particular predominantly or completely, covered downwards by the protective plate 2 in the vertical direction 8 of the vehicle. As a result, the electrical energy storage device 14 is, or can be, protected at least from explosive impact by the protective plate 2.

[0057] For example, the protective plate 2 is held at least indirectly, in particular directly, on the body 5 via at least one fastening region 17 of the protective plate 2.

[0058] In order to be able to particularly increase the security of the electrical energy storage device 14 against damage and deformation and to be able to keep the manufacturing costs of the special armored vehicle 4 particularly low, it is provided that the protective plate 2 with respect to the body 5, in particular the respective side sills 11, and the electrical energy storage device 14 are held exclusively on the body 5, for example via the fastening area 17. This means that the protective plate 2 and the electrical energy storage device 14 are each fastened to the body 5 independently of one another via the connection area 16 and the fastening area 17, respectively.Thus, for example, the electrical energy storage device 14 is exclusively held to the body 5 via the connection area 16 with respect to the electrical energy storage device 14 and the protective plate 2, and the protective plate 2 is exclusively held to the body 5 via the fastening area 17 with respect to the protective plate 2 and the electrical energy storage device 14. This allows a connection or the fastening of the protective plate 2 to the body 5 to be decoupled from the electrical energy storage device 14. This allows at least one connection of the electrical energy storage device 14 to be used across all construction variants for the special protection vehicle and for another non-armored vehicle.

[0059] In the exemplary embodiment, it is provided that the protective plate 2 extends in the vehicle transverse direction 10 at least as far as the side sills 11 of the special protection vehicle 4.

[0060] In a further embodiment, it is further provided that the protective plate 2 is held on at least one of the side sills 11. In the exemplary embodiment, the protective plate 2 is held on the side sills 11, i.e., with respect to the vehicle's transverse direction, it is attached to both sides of the side sills 11. This means that, with respect to the respective side sill 11 and the electrical energy storage device 14, the protective plate is held on the body 5 exclusively via the respective side sill 11.

[0061] In the exemplary embodiment, it is provided that the electrical energy storage device 14 is held on the side sills 11, in particular via its storage housing 15. This means that the electrical energy storage device 14 is held on the body 5 via the side sills 11.

[0062] In a further embodiment, it is provided that the protective plate 2 and the respective side sill 11 are spaced apart from one another in the vehicle vertical direction 8 and the protective plate 2 is held on the respective side sill 11 by means of at least one intermediate element 18 arranged in the vehicle vertical direction 8 between the respective side sill 11 and the protective plate 2.

The intermediate elements 18 are arranged in the vehicle vertical direction 8 between the respective side sill 11 and the protective plate 2. Preferably, the respective intermediate element 18 is designed as a respective spacer bushing 19.

For example, the respective receiving element 20 is arranged at least partially, in particular predominantly or completely, in the vehicle vertical direction 8 above a sill base 11a of the respective side sill 11. In the exemplary embodiment, a plurality of receiving elements 20, designed, for example, as a threaded bushing, are arranged, in particular held, on the respective side sill 11. A screw element 21, which is arranged on the protective plate 2 and extends through the respective intermediate element 18, is screwed to the respective receiving element 20 in order to hold the protective plate 2 to the side sill 11, in particular to a respective sill part 24 of the respective side sill 11 and / or to the sill base 11a, by means of a respective screw connection 22.For example, the respective receiving element 20 is arranged, in particular held, in particular directly, on the respective sill part 24 and / or on the respective sill base 11a of the respective side sill 11. The respective sill part 24 is arranged, for example, within the respective side sill 11. This means that the respective side sill 11 has, for example, at least one cavity in which the respective sill part 24 is arranged.

[0065] It can therefore be provided that the protective plate 2 is not connected, in particular directly, to the electrical energy storage device 14, in particular to its storage housing 15, but is connected separately to the respective side sill 11 via bushings, in particular the respective spacer bushing and the respective threaded bushing. In particular, the respective protective plate 2 is arranged in the vehicle vertical direction 8 between a respective screw head of the respective screw element 21 and the respective intermediate element 18. The respective screw element 21 is designed, for example, as a respective screw. Fig. Figure 5 shows a schematic and perspective partial sectional view of the assembly 1 in a first sectional plane, in which the respective screw connection 22 is illustrated. For example, the sill part 24 is connected, in particular directly, to the inner part 13. As shown by way of example in Fig. 3 and in Fig. 5, the respective screw head of the respective screw element 21 is, for example, at least partially, in particular predominantly or completely, preferably countersunk in the protective plate 2.

[0066] It is provided that the electrical energy storage device 14, in particular the storage housing 15, has at least one profile, which in the exemplary embodiment is designed as an extruded profile 25, in particular an extruded aluminum profile.

[0067] As exemplified in Fig. 4 and Fig. As shown in Figure 5, the exemplary embodiment provides for the extruded profile 25 to have at least one through-opening 26, in particular a plurality of through-openings 26. Each of the intermediate elements 18 is guided through the respective through-opening 26.

[0068] Fig. 6 shows the arrangement 1 in a schematic and perspective partial sectional view in a second sectional plane, which is arranged, for example, in front of or behind the first sectional plane in the vehicle longitudinal direction 27. In a further embodiment, it is provided that at least one respective coupling element 28 is arranged, in particular held, on the respective side sill 11. In the exemplary embodiment, it is provided that a plurality of coupling elements 28, for example designed as respective threaded bushings, are arranged, in particular held, on the side sill 11, in particular on the respective sill part 24 of the respective side sill 11.A second screw element 29, arranged on the extruded profile 25, is screwed, in particular directly, to the respective coupling element 28 in order to hold the electrical energy storage device 14, via the extruded profile 25, by means of at least one second screw connection 30, in particular at least indirectly or directly, to the respective side sill 11, in particular to the respective sill part 24. The screw elements 21, 29 are formed separately from one another. The screw connections 22, 30 are different from one another, in particular formed separately from one another.

[0069] In the exemplary embodiment, the respective coupling element 28 is arranged at least in part, in particular predominantly or completely, in the vehicle vertical direction 8 above the sill base 11a of the respective side sill 11.

[0070] In the exemplary embodiment, it is provided that the electrical energy storage device 14 is held on the respective side sill 11, in particular on the respective sill base 11a or the respective sill part 24, via the extruded profile 25 through the intermediary of at least one second intermediate element 31, in particular a plurality of second intermediate elements 31. The respective second intermediate element 31 is, for example, annular, i.e., designed as a respective intermediate ring or as a respective intermediate disk. In the exemplary embodiment, the respective screw element 29 is guided through a respective one of the second intermediate elements 31. By means of the respective second intermediate element 31, for example, a galvanic isolation can be brought about between the extruded profile 25 and the respective side sill 11.

[0071] As in Fig. 4, it is provided, for example, that at least one of the second screw connections 30 or more of the second screw connections 30 are arranged between each of the first screw connections 22 in the vehicle's longitudinal direction 27. This means that at least one of the coupling elements 28 are arranged between each of the receiving elements 20 in the vehicle's longitudinal direction 27. The screw connections 22, 30 are thus arranged offset from one another, for example, in the vehicle's longitudinal direction 27.

[0072] In the exemplary embodiment, it is provided that the protective plate 2 is made of aluminum 32.

[0073] As in Fig. 5 and Fig. 6, it is provided, for example, that the storage housing 15 has the extruded profile 25 as the first housing part 33 and at least one second housing part 34, which is designed, for example, as a cover and is in particular formed separately from the first housing part 33. The housing parts 33, 34 are screwed together, for example. For example, a receiving space 14a designed to accommodate storage elements 14b of the electrical energy storage device 14 is delimited or formed by the first housing part 33 at least in the vehicle transverse direction 10. Alternatively or additionally, the receiving space 14a is delimited or formed, for example, by the second housing part 34 in the vehicle vertical direction 8, in particular upwards, and / or in the vehicle transverse direction 10, in particular outwards.

[0074] For example, a plurality of transverse elements 35, in particular designed as cross members, are provided which extend in the vehicle transverse direction 10 between the side sills 11, wherein the side sills 11 are supported on one another, for example via the transverse elements 35 in the vehicle transverse direction 10, in particular at least indirectly or directly. In the exemplary embodiment, the transverse elements 35 are spaced apart from one another. For example, the electrical energy storage device 14 has a plurality of modules, wherein at least one of the modules is arranged between the transverse elements 35. The modules are thus separated from one another, for example by the transverse elements 35 or by means of the transverse elements 35. The respective module can be understood in particular to mean a respective cell module. For example, the respective module each has a plurality of the storage elements 14b of the electrical energy storage device 14.

[0075] Fig. 7 shows the arrangement 1, in particular the protective plate 2 and the electrical energy storage device 14, in a schematic plan view according to a further embodiment. Preferably, all storage elements 14b of the electrical energy storage device 14 are covered downwards in the vehicle vertical direction 8 by the protective plate 2. In particular, at least the receiving space 14a, i.e., at least the storage elements, are covered downwards by the protective plate 2 over a complete length 36 of the receiving space 14a extending in the vehicle longitudinal direction 27 and over a complete width 37 of the receiving space 14a extending in the vehicle transverse direction 10.

[0076] It is provided that the storage housing 15, in particular at least one housing element 15a of the storage housing 15, at least partially delimits the at least one receiving space 14a, in which at least one storage element 14b, in particular at least one storage cell, of the electrical energy storage device 14 is arranged or is to be arranged. Furthermore, the extruded profile 25 of the storage housing 15 has at least one cavity 39 which is at least partially delimited by at least one wall 38 of the extruded profile 25. This is, for example, in Fig. 3, Fig. 5 and Fig. 6 and in Fig. 8, in which the arrangement of the electrical energy storage device is shown in a schematic and perspective further partial sectional view.

[0077] In order to be able to particularly increase the safety against damage and deformation of the electrical energy storage device 14 in a particularly low-cost manner, it is provided that at least one protective element 40 is arranged in the cavity 39, which is formed separately from the wall 38, in particular separately from the extruded profile 25, by means of which the electrical energy storage device 14 is protected from explosives, shelling, and / or the like. Preferably, the receiving space 14a is at least partially, in particular predominantly or completely, preferably outwardly, covered by the protective element 40 in the vehicle transverse direction 10.

[0078] Thus, an insert, in particular a ballistic insert, can be created in the form of the protective element 40, which can be integrated laterally into the extruded profile 25 with respect to the vehicle transverse direction 10, which is designed, for example, as a crash profile.

[0079] In the exemplary embodiment, the wall 38 has four wall regions 41, 42, 43, 44. A first of the wall regions 41 delimits the cavity 39 in the vehicle vertical direction 8, in particular directly downwards. A second of the wall regions 42 delimits the cavity 39 in the vehicle vertical direction 8, in particular directly upwards. A third of the wall regions 43 delimits the cavity 39 inwards in the vehicle transverse direction 10. The fourth of the wall regions 44 delimits the cavity 39 outwards in the vehicle transverse direction 10. In the exemplary embodiment, it is provided that the protective element 40 extends obliquely to the wall 38, in particular obliquely to the wall regions 41 to 44. Furthermore, it is provided in the exemplary embodiment that the protective element 40 extends obliquely to the vehicle vertical direction 8 and / or obliquely to the vehicle transverse direction 10. It is preferably provided that the protective element 40 extends in the vehicle longitudinal direction 27.

[0080] For example, in Fig. 8, a further embodiment provides for a cross-sectional area 45 of the cavity 39 to be divided by the protective element 40 into two equally sized cross-sectional area parts 46, 47. A first of the cross-sectional area parts 46 is, for example, delimited, in particular directly, by the second and third wall regions 42, 43. The second of the cross-sectional area parts is, for example, delimited, in particular directly, by the first and fourth wall regions 41, 44. For example, the first cross-sectional area part 46 is arranged on a side of the protective element 40 that points inwards in the vehicle transverse direction 10 and upwards in the vehicle vertical direction 8. For example, the second cross-sectional area part 47 is arranged on a side of the protective element 40 that points downwards in the vehicle vertical direction 8 and outwards in the vehicle transverse direction 10.

[0081] In order to be able to keep the manufacturing costs of the storage housing 15 particularly low, it is preferably provided that the protective element 40 is or will be inserted into the cavity 39, in particular in the vehicle longitudinal direction 27.

[0082] For example, it is provided that the protective element is arranged further outward in the transverse direction of the vehicle than the fastening region 17 and / or the connection region 16, in particular the receiving element 20 and / or the coupling element 28.

[0083] For example, it is provided that the storage housing 15 has at least two extruded profiles 25, wherein a first of the extruded profiles 25 is arranged on a first side of the electrical energy storage device 14, in particular of the storage housing 15, and the second of the extruded profiles is arranged on a second side of the electrical energy storage device 14, in particular of the storage housing 15, opposite the first side in the vehicle transverse direction 10. For example, the respective extruded profile 25 has at least one respective cavity which is at least partially delimited by at least one wall 38 of the respective extruded profile, in which at least one respective protective element 40 is arranged, which is formed separately from the respective wall 38 and by means of which the electrical energy storage device 14 is protected from explosive attack, shelling or the like.

[0084] In a further embodiment, it is provided that the extruded profile 25 extends outward in the vehicle transverse direction 10 up to the side sill 11. Thus, the extruded profile 25 extends, for example, outward in the vehicle transverse direction 10 up to at least the first side sill 11, and the second extruded profile extends, for example, outward in the vehicle transverse direction 10 up to at least the second side sill 11.
