[0006] It is an object of the invention to provide an arrangement of an electrical energy storage device in an electrically driven special protection vehicle, so that safety against damage or deformation of the electrical energy storage device can be particularly increased and manufacturing costs for the special protection vehicle can be kept particularly low.

[0007] This object is achieved according to the invention by an arrangement of an electrical energy storage device in an electrically powered special protection vehicle having the features of patent claim 1. Advantageous embodiments of the invention are the subject of the dependent patent claims and the description.

[0008] The invention relates to an arrangement of an electrical energy storage device, in particular in an underbody area, in an electrically driven special-armored vehicle. The arrangement preferably comprises at least one, in particular armored, protective device. The electrical energy storage device can be understood, in particular, as an electrical energy storage device of the special-armored vehicle. Thus, the special-armored vehicle preferably comprises, in particular in its fully manufactured state, the electrical energy storage device and, in particular, the protective device. 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. The protective device preferably comprises the armor plating or at least part of the armor plating. Thus, the integrated armor plating of the special protection vehicle is, for example, at least partially formed by the protective device. The special protection vehicle can have additional protective elements, in particular armor plating elements, formed separately from the protective device. The special protection vehicle can therefore also be referred to as an armored 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, in particular purely electrically. Thus, the special protection vehicle is a battery-electric vehicle or a hybrid vehicle. In other words, the special protection vehicle is preferably designed 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] The underbody area of the special protection vehicle can be understood in particular as an underfloor area. Furthermore, the underbody area can be understood in particular as a lower area or lower partial area of the special protection vehicle with respect to a vehicle vertical direction of the special protection vehicle. The underbody area extends, for example, with respect to the vehicle vertical direction, beneath 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. For example, the body delimits an interior of the special protection vehicle at least partially, in particular predominantly or completely. The interior space, which can be referred to in particular as the vehicle interior, can be understood as a passenger compartment and / or a passenger cell, for example.

[0012] The fact that the electrical energy storage device is to be arranged or is arranged in the underbody area can be understood in particular to mean that the electrical energy storage device is to be arranged or is arranged under the floor element in the vertical direction of the vehicle.

[0013] The electrical energy storage device has at least one fastening area, via which the electrical energy storage device is held in the underbody area of the special-armored vehicle. An interior of the special-armored vehicle is at least partially delimited in the transverse direction of the vehicle by a body component, in particular an armored one. The electrical energy storage device is at least partially covered in the transverse direction of the vehicle by at least one protective element, in particular the protective device, formed separately from the body component, whereby the electrical energy storage device is protected by the protective element from explosives, shelling, or the like.

[0014] The electrical energy storage device preferably has at least one storage housing which at least partially, in particular predominantly or completely, delimits or forms at least one receiving space. At least one storage element of the electrical energy storage device is or is arranged in the receiving space. A plurality of storage elements of the electrical energy storage device are or are arranged in the receiving space. The respective storage element is preferably designed as a respective storage cell. The electrical energy storage device preferably has a plurality of modules, in particular cell modules, wherein a plurality of the modules are or are arranged in the receiving space. The respective module preferably has a plurality of the storage elements.

[0015] The electrical energy storage device is designed, for example, as a battery or accumulator. 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. In other words, the electrical energy storage device is preferably designed, in particular, as an electrical traction storage device, in particular a traction battery.

[0016] 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.

[0017] The protective device comprises, in particular, at least one, in particular armored, protective element, by which or by means of which the electrical energy storage device can be covered or covered at least partially, in particular predominantly or completely, in the transverse direction of the special armored vehicle, in particular towards the outside. In other words, the protective element is arranged at least indirectly next to the electrical energy storage device in the transverse direction of the special armored vehicle, in particular at least partially at the same height with respect to a vertical direction of the special armored vehicle. As a result, the electrical energy storage device is or can be protected by means of the protective element from explosives, shelling, and / or the like.In other words, the protective element is designed to protect the electrical energy storage device, in particular the receiving space or the at least one storage element, arranged behind it, in particular further inward than the protective element in relation to the vehicle's transverse direction. Blasting can be understood in particular as an explosion or detonation, for example caused by explosives. For example, blasting is an explosion caused or induced by a hand grenade. Firing can be understood in particular as firing at the special armored vehicle with a firearm, in particular with a projectile.

[0018] In order to be able to particularly increase the safety of the electrical energy storage device against damage and deformation of the electrical energy storage device and to be able to keep the manufacturing costs of the special protection vehicle particularly low, it is provided that the protective element has at least one fastening area, via which the protective element is held on the body component, in particular directly, and the protective element extends further downwards in the vertical direction of the vehicle than the body component.This means that the protective element is to be or is to be held via the fastening area, in particular at least indirectly or directly, on the body component that at least partially delimits the interior of the special armored vehicle in the transverse direction of the vehicle, wherein the protective element, in particular in its installed position on the body component or in the special armored vehicle, extends further downward in the vertical direction of the vehicle than the body component. For example, the protective element is made of armored steel.

[0019] The fact that the protective element is to be held or held above the fastening area on the body component can be understood in particular to mean that the protective element can be fastened or is fastened to the body component at least indirectly, in particular directly, above the fastening area. The fact that the protective element extends further downwards in the vertical direction of the vehicle than the body component can be understood in particular to mean that the protective element is arranged at least partially further down in the vertical direction of the vehicle than the body component. The protective element can therefore be arranged at least partially below the body component in the vertical direction of the vehicle. The body component can be understood in particular to mean a structural element of the body of the special armored vehicle. The body component is designed, for example, as a side wall, in particular as a side wall part, for example as the inner part of the side wall.The side wall can be understood in particular as a side frame of the body.

[0020] The invention is based in particular on the following findings and considerations: In principle, it would be conceivable to extend the, in particular armored, body component downwards in the vertical direction of the vehicle to protect the electrical energy storage device in order to at least partially cover the electrical energy storage device in the transverse direction of the vehicle. In contrast, in the protective device according to the invention, the protective element formed separately from the body component is provided to at least partially cover the electrical energy storage device in the transverse direction of the vehicle. As a result, the body component, which is in particular cross-model, can be used both by the electrically powered special armored vehicle and for another special armored vehicle that is different from the electrically powered special armored vehicle and is driven by an internal combustion engine, in particular one that is driven solely by an internal combustion engine.Thus, by means of the body component, which is in particular identical and is used across all construction variants, both a first construction variant of the special protection vehicle and a second construction variant of the special protection vehicle can be represented, wherein the first construction variant is the electrically driven special protection vehicle and the second construction variant is a special protection vehicle with at least one internal combustion engine which is intended to drive the special protection vehicle. In this way, the number of identical parts can be increased significantly across construction variants. As a result, the manufacturing expenditure for the special protection vehicle can be kept particularly low. By connecting at least one protective component in the form of the protective element to the body, the electrical energy storage device can be protected, for example against projectiles penetrating the electrical energy storage device, in particular the cell modules, by firing.This makes it possible to reliably prevent the electrical energy storage device from being switched off, particularly by short-circuiting, and / or damage to storage cells, particularly charged ones. The storage cells can be referred to as energy cells. The protective device according to the invention can thus protect the electrical energy storage device of the electrically powered special armored vehicle from fire, thereby providing ballistic protection for the electrical energy storage device.

[0021] Furthermore, it is provided that a profile, for example an extruded profile, of a storage housing of the electrical energy storage device is arranged further down in the vertical direction of the vehicle than the protective element, at least in some regions. In other words, the profile, in particular an extruded profile, of the storage housing extends further down in the vertical direction of the vehicle than the protective element in some regions. This means that the storage housing is free of any covering of the profile by the protective element in the transverse direction of the vehicle, at least in a partial region. As a result, the protection of the electrical energy storage device, in particular against bullets and / or explosives, can be provided in a first height range by the protective element and in a second height range adjoining the first height range downwards in the vertical direction of the vehicle by the profile, which can be reinforced and / or at least partially armored, for example.This allows the storage housing, for example, to be designed across all construction variants, at least in its basic structure, and the profile to be locally reinforced or armored. This eliminates the need for particularly extensive redesign of the storage housing, thereby keeping the manufacturing costs of the special armored vehicle particularly low. The profile can have at least one additional, particularly armored, protective element, in particular one formed separately from the protective element. In other words, the profile can be equipped with an additional integrated protective element.

[0022] Preferably, the body component protects or can be protected from fire, explosives, and / or the like by means of the body component. In other words, the body component is preferably designed as an armored body component. For example, the body component is made of armored steel. Particularly if the body component is armored, the body component can typically be particularly complex, and in particular particularly cost-intensive, to manufacture, making it particularly advantageous in terms of manufacturing costs to be able to use the body component, in particular as a common part, across different design variants.

[0023] In a further embodiment, it is provided that the protective element is arranged or is arranged at least partially within a side sill of the special protection vehicle, in particular the body of the special protection vehicle. In other words, the protective element extends, in particular in its installed position in the special protection vehicle or on the body component, at least partially, in particular predominantly or entirely, within the side sill. As a result, the electrical energy storage device can be particularly well protected by means of the protective element. Furthermore, the side sill can be designed, in particular at least largely, across all construction variants, whereby the manufacturing costs of the special protection vehicle can be kept particularly low.

[0024] In a further embodiment, it is provided that the electrical energy storage device, in particular the receiving space, can be covered or concealed by the protective element, in particular at least partially, at least substantially over its entire length extending in the longitudinal direction of the special armored vehicle in the transverse direction of the vehicle. In other words, a length extending in the longitudinal direction of the vehicle, in particular the entire length, of the protective element corresponds at least substantially to the entire length of the electrical energy storage device, in particular of the receiving space, extending in the longitudinal direction of the vehicle. This allows the electrical energy storage device to be particularly well protected. For example, all storage cells of the electrical energy storage device can be covered or concealed at least partially in the transverse direction of the vehicle by the protective element.

[0025] In a further embodiment, the protective device has at least one front, in particular armored, protective element, in particular formed separately in the protective element, by which or by means of which the electrical energy storage device, in particular the receiving space, can be covered at least partially, in particular predominantly or completely, to the front in the longitudinal direction of the special armored vehicle. This means that the electrical energy storage device is arranged behind the front protective element with respect to the vehicle's longitudinal direction. In other words, the front protective element is designed to shield the electrical energy storage device to the rear in the vehicle's longitudinal direction. As a result, the electrical energy storage device is protected by the front protective element from explosives, ballistic attacks, and / or the like.In other words, the front protective element is designed to protect the electrical energy storage device located behind the front protective element in relation to the vehicle's longitudinal direction. This allows the electrical energy storage device to be particularly well protected against external attacks. This significantly increases the security against damage and deformation of the electrical energy storage device. For example, the front protective element is made of armored steel. For example, all storage cells of the electrical energy storage device can be or are at least partially covered by the front protective element toward the front in the vehicle's longitudinal direction.

[0026] In a further embodiment, the protective device has at least one rear, in particular armored, protective element, which is designed in particular separately from the protective element and the front protective element, and by means of which the electrical energy store, in particular the receiving space, can be covered or is covered at least partially, in particular predominantly or completely, towards the rear in the vehicle's longitudinal direction. This means that the electrical energy store is arranged in front of the rear protective element in the vehicle's longitudinal direction. In other words, the rear protective element is designed to shield the electrical energy store towards the rear in the vehicle's longitudinal direction. As a result, the electrical energy store is protected by the rear protective element from explosive attack, shelling, and / or the like. In other words, the rear protective element is designed to protect the electrical energy store.This allows the electrical energy storage unit to be particularly well protected against external attacks. This significantly increases the safety against damage and deformation of the electrical energy storage unit. For example, the rear protective element is made of armored steel. For example, all storage cells of the electrical energy storage unit can be or are covered at least partially by the rear protective element in the longitudinal direction of the vehicle.

[0027] For example, the special protection vehicle, in particular the body, has at least one second body component which is spaced apart from the body component in the transverse direction of the vehicle and which at least partially, in particular predominantly or completely, delimits the interior space. For example, the body component, which can in particular be referred to as the first body component, is arranged on a first side of the special protection vehicle, in particular the body, in the transverse direction of the vehicle, and the second body component is arranged on a second side of the special protection vehicle, in particular the vehicle body, which is different from the first side and in particular opposite the first side in the transverse direction of the vehicle. The body components are, for example, structurally identical.

[0028] For example, the protective device has at least one second, in particular armored, protective element, which is in particular formed separately from the protective element and by which the electrical energy storage device can be or is covered at least partially, in particular predominantly or completely, in the transverse direction of the special armored vehicle. As a result, the electrical energy storage device is protected by the second protective element from explosives, shelling, and / or the like. The protective elements are preferably spaced apart from one another in the transverse direction of the vehicle. For example, the protective element, which can in particular be referred to as the first protective element or as the first lateral protective element, is arranged on the first side, and the second protective element, which can in particular be referred to as the second lateral protective element, is preferably arranged on the second side.

[0029] For example, it is provided that the second protective element has at least one second fastening region, via which the second protective element is to be or is held on the second body component, extending further downward in the vertical direction of the vehicle than the second body component, in particular at least indirectly or directly. The protective elements are preferably of identical construction.

[0030] In a further embodiment, it is provided that the electrical energy storage device can be or is covered at least in part completely around its circumference in the circumferential direction of the electrical energy storage device by the protective device, in particular by the first protective element, the second protective element, the front protective element and the rear protective element. This means that the electrical energy storage device, in particular the receiving space, is or will be surrounded at least in a partial area completely around its circumference in the circumferential direction by the protective device, in particular by the first and second protective elements as well as the front and rear protective elements. The protective device is thus designed, for example, as a housing for the electrical energy storage device, wherein this housing completely surrounds the electrical energy storage device at least in the circumferential direction.This allows the electrical energy storage device to be particularly well protected against external attacks. This significantly increases the safety against damage and deformation of the electrical energy storage device.

[0031] In a further embodiment, the protective device has at least one protective plate, by which the electrical energy storage device can be or is covered at least partially, in particular predominantly or completely, downwards in the vertical direction of the vehicle. In other words, the protective plate extends in the vertical direction of the vehicle below the electrical energy storage device, in particular below the receiving space. This means that the electrical energy storage device is or can be shielded at least partially downwards in the vertical direction of the vehicle by means of the protective plate. As a result, the electrical energy storage device is or can be protected by means of the protective plate against blasting, shelling and / or the like. In other words, the protective plate is designed to protect the electrical energy storage device arranged above it in the vertical direction of the vehicle.This allows the electrical energy storage device to be particularly well protected against external attacks, for example, against a hand grenade detonating beneath the armored vehicle. This significantly increases the security of the electrical energy storage device against damage or deformation. The protective plate can be understood, in particular, as an armored protective plate. The protective plate is preferably made of aluminum, in particular an aluminum alloy. It is possible for the protective plate to comprise other materials and / or composite materials, for example, depending on requirements. Alternatively or additionally, the protective plate can be constructed in a layered manner.

[0032] Overall, it is evident that the integration and connection of ballistic protection components in the form of protective devices for the electrical energy storage unit on the body of electrified security vehicles is feasible. Protective components in the form of protective elements can be connected around the electrical energy storage unit to ensure complete protection of the electrical energy storage unit, for example, to protect against all possible firing angles.

[0033] Preferably, the armored vehicle, in particular the interior, is protected by the body component against explosives, gunfire, or the like. In other words, the body component is preferably armored, i.e., designed as an armored body component. This allows the armored vehicle to be particularly well protected against external attacks.

[0042] The electrical energy storage device 17 has at least one receiving space 18 in which at least one storage element of the electrical energy storage device 17 is to be arranged or is arranged. Preferably, a plurality of storage elements are arranged in the receiving space 18. Preferably, the receiving space 18 is delimited or formed at least in part, in particular predominantly or completely, by a storage housing 19 of the electrical energy storage device 17.

[0043] The protective device 2 has at least one protective element 20, by which the electrical energy storage device 17, in particular the receiving space 18, can be at least partially covered or covered in the vehicle transverse direction 8. In the exemplary embodiment, the protective device 2 has two protective elements 20, 21, by which the electrical energy storage device 17, in particular the receiving space 18, can be at least partially covered or covered in the vehicle transverse direction 8, in particular on both sides. A first of the protective elements 20 is arranged on the first side 6, and the second protective element 21 is arranged on the second side 7.

[0044] For example, the side walls 4, 5, the roof element 10, the front bulkhead 12, and / or the rear wall 14 at least partially form an armored passenger compartment of the special protection vehicle 1. Thus, the respective side walls 4, 5, the roof element 10, the front bulkhead 12, and / or the rear wall 14 are armored, i.e., at least partially formed from armored steel. Thus, the special protection vehicle 1, in particular the interior 9, is protected or can be protected from explosives, shelling, and / or the like, for example, by means of the respective side walls 4, 5, the roof element 10, the front bulkhead 12, and / or the rear wall 14.

[0053] It is preferably provided that the electrical energy storage device 17, in particular the receiving space 18, can be covered or is covered by the front and / or rear protective element 28, 30 at least substantially over its total width 32 extending in the vehicle transverse direction 8 in the vehicle longitudinal direction 13.
