Definitions
- Energy storage housing motor vehicle, electrical energy storage and series
- the present invention relates to an energy storage housing, in particular a high-voltage storage housing for a motor vehicle, a motor vehicle, an electrical energy storage device's and a series of energy storage housings.
- Energy storage housing of the type in question z. B. used in partially and fully electrified motor vehicles.
- the batteries or battery modules are installed in such housings.
- the memory or housing is often very large, which is not unproblematic in terms of economical series production.
- One of the reasons why the production of such housings is not unproblematic is that the housings have to meet high requirements in terms of gas tightness.
- an energy storage housing in particular a high-voltage storage housing for a motor vehicle, comprises an upper housing part and a lower housing part, the lower housing part having a central section and two end sections, the central section comprising a base element on which wall elements are formed on the sides, which extend along a longitudinal axis extend, as a result of which an arrangement space is formed in some areas together with the floor element, and the end sections which have wall elements which also form the arrangement space are arranged at the ends of the central section, the end sections being cast parts and the shape of the central section being produced by bending.
- the arrangement space is expediently upwards closed towards the upper part of the housing, which is suitably fastened to the lower part of the housing.
- the central section formed by bending and the cast end sections enable a substantially cuboid arrangement space.
- a cuboid arrangement space which does not have any larger radii etc., enables a maximum transport volume.
- disruptive radii such as those that occur, for example, in deep drawing, in bending or, in particular, in bending, can be avoided.
- the middle section is a bent plastic and/or metal part.
- the metal part is a steel sheet or, in particular, an aluminum sheet, which is bent in a suitable manner or, in particular, is formed by bending or correspondingly folded.
- the middle section can also be referred to as an edge part.
- the wall elements extend perpendicularly or essentially perpendicularly away from the floor element.
- the middle section can also be made of plastic or of a composite material, such as a carbon-fiber-reinforced plastic.
- the middle section is designed, for example, as an SMC component (SMC Sheet Molding Compound). The shaping that occurs in the SMC tool is also interpreted as bending.
- plastic or composite components can also be bent or folded.
- flange elements are formed adjacent to the wall elements, which are preferably oriented parallel to the floor element. These preferably extend parallel to the floor element away from the arrangement space, shaped as a flange or flange area.
- the flange elements which in particular are designed circumferentially and are formed both on the middle section and on the end sections, form a circumferential flange area.
- the upper part of the housing is expediently fastened to the lower part of the housing, in particular in a gas-tight manner, in a positive and/or non-positive manner.
- the attachment or connection is expediently detachable.
- Preferred fasteners include screw and/or rivet connections.
- the curved or, in particular, beveled middle section comprising the wall elements and the flange sections adjoining them, has a very high degree of dimensional accuracy due to the process.
- the flatness of the surfaces In particular, the flange elements are very flat and not wavy, as would be the case, for example, when deep-drawing such a structure. Flange elements that are not dimensionally accurate or, in particular, wavy would prevent or at least make it more difficult to arrange the housing cover tightly.
- One or more fastening elements are formed on the flange elements or on the flange region in order to fasten the upper part of the housing.
- This can be correspondingly designed recesses or holes, which are used for the arrangement of fastening means, such as screws.
- the flange elements or the flange area also serve to fasten the energy storage housing in the respective motor vehicle.
- the flange elements in particular the lateral flange elements, or the corresponding flange regions, are used to fasten the energy storage housing to the longitudinal beams of the motor vehicle.
- the end sections are produced as one part, in particular by die-casting.
- the end sections are expediently made from a metal II material, in particular from a light metal such as, for example, an aluminum alloy. Alternatively, production from a plastic or, in particular, a composite material is also preferred.
- a front section and a rear end section With respect to the direction of travel, when the energy storage case is installed in the motor vehicle, there is a front section and a rear end section.
- the end sections can be designed identically at the front and rear. However, they typically differ at least slightly, since they have or form different connection points. Notwithstanding, they can conveniently be initially created as one part.
- this one part which according to a preferred embodiment is a die-cast component, is mechanically separated.
- a preferred separation method here is sawing, for example.
- the end sections include wall elements, since they form the order space with. Preferably, but not necessarily, they also have flange elements. They are therefore expediently designed to continue or complete a shape or geometry of the middle section. According to a preferred embodiment, the end sections also have floor elements. According to one embodiment, the end sections are connected to the middle section in a cohesive manner along a joining plane, with the joining plane being sealed. According to a preferred embodiment, the end sections are positively and/or non-positively connected to the middle section, in particular screwed and/or riveted.
- the end sections are attached to the central section using a fusion welding process, in particular using MIG welding (metal inert gas welding).
- MIG welding metal inert gas welding
- This method can be implemented with process reliability and is cost-effective.
- the tightness, in particular gas tightness, is preferably produced subsequently at this point or along the weld seam by means of a sealing material applied to the connection or joint.
- the order is applied, for example, in the form of a bead, along the weld seam, on one or both sides.
- the joining areas or the joining plane are subsequently sealed, a sealing material being used for this purpose.
- the sealing material is selected from one of the following materials: silane-modified polymer, 2K (2-component) polyurea and/or polyvinyl chloride. It has been found that the aforementioned materials, in particular in connection with the application on, preferably bare, aluminum material provide optimal fluid tightness, in particular gas tightness. The use of a sealing material made from or based on silane-modified polymers or a silane-modified polymer is particularly preferred.
- the lower housing part has a base element which, when the energy storage housing is installed, is oriented essentially parallel to the plane of the road.
- the wall elements extend away from the floor element essentially perpendicularly (upward in relation to the roadway level or floor level). Together with the end sections, this results in a circumferentially closed arrangement space.
- the joining plane is oriented flat or perpendicular to the floor element.
- this makes it easier to attach the end sections to the middle section, since you only have to work along one line.
- any subsequent sealing is also made easier, since no complicated geometries have to be sealed here either.
- the two parts also have a parting plane that is also expediently straight or flat.
- the arrangement space is particularly preferably barrier-free.
- no further elements be they transverse elements or longitudinal elements, are provided for stiffening, etc., in the arrangement space.
- the space can be fully used to accommodate as large a number of energy storage cells as possible.
- a multiplicity of energy storage cells is expediently arranged in the arrangement space in a space-filling manner.
- Preferred types of housing cells are, for example, prismatic cells or, in particular, round cells, which are expediently arranged in particular on edge, possibly also in several levels.
- the invention also relates to a motor vehicle, comprising a front end and a rear end, which are connected via longitudinal elements, and wherein an energy storage housing according to the invention is fastened, in particular load-free, to the longitudinal elements.
- the front end and the rear end expediently form the supporting structure in combination with the longitudinal elements, while the energy storage housing is only arranged load-free on this structure or, in particular, is fastened positively and/or non-positively, in particular also detachably.
- the energy storage housing does not have to absorb any forces.
- the energy storage housing can primarily be designed to accommodate as many energy storage cells as possible.
- the upper housing part of the energy storage housing forms a floor of the vehicle interior.
- cross members are arranged on the upper housing part, in particular arranged in a positive and/or non-positive manner, for example by means of screw connections, the cross members being designed for seat rail fastening.
- the cross members are also called seat cross members.
- the seat cross members are connected to the longitudinal elements or attached to them. This can also be used in the transverse direction in the area of the energy storage cher housing stiffening of the aforementioned structure take place. Expediently, however, not via the energy storage housing itself but via the cross member, to which the energy storage housing is attached only via its upper housing part, which, as mentioned, preferably forms the floor of the vehicle interior.
- the invention also relates to an electrical energy storage device, in particular a high-voltage storage device, which includes an energy storage device housing according to the invention.
- an electrical energy storage device comprises a large number of electrical energy storage cells, in the present case, for example, lithium ion cells, lithium sulfur cells, iron phosphate cells, etc.
- Energy storage cells can also be capacitors or supercapacitors.
- the energy storage cells are combined to form modules, in particular battery modules.
- An energy store includes z. B. a variety of such battery modules.
- such a module structure is dispensed with.
- the energy storage cells are arranged directly in the arrangement space, with the barrier-free arrangement space proposed here, essentially shaped over the three parts central section, front and rear end section, bringing great advantages with regard to the possible arrangement volume.
- the lack of internal cross or longitudinal members should be mentioned here as a particular advantage. The same applies to the very small radii that can be achieved by bending or edging, which enable optimal use of space.
- the invention also relates to a series of energy storage housings, comprising a large number of energy storage housings according to the invention, the width and length of the energy storage housing being adapted via appropriately shaped, in particular curved, central sections.
- the middle sections differ only in their length.
- the end sections are preferably identical parts.
- the front and rear end sections are expediently designed differently in each case.
- the respective front end sections or the respective rear end sections are of the same or substantially the same design within the series. This is not opposed to the fact that, for example, holes or the like are subsequently introduced which can, whereby the end sections can be individualized as required.
- the basic components are expediently the same in each case, as a result of which energy storage housings of different sizes can be provided for use in vehicles of different sizes in a process-safe and cost-effective manner.
- the middle sections are additionally or alternatively of different widths. This can be implemented with little effort, since they are formed by bending or, in particular, bending.
- the end sections are correspondingly wider or narrower out forms. This can also be implemented with little effort.
- FIG. 1 a top view of an embodiment of a lower housing part
- FIG. 2 a section as outlined in FIG. 1;
- FIG. 3 a side view of the lower housing part known from FIG. 1, as outlined in FIG. 1;
- Fig. 1 shows a schematic representation of a plan view of a housing bottom part 2 of an energy storage housing.
- a central section 20 can be seen, which extends along a longitudinal direction L, with an end section 30 being arranged at each end.
- the middle section 20 has a bottom element 22 .
- the end sections 30 are also shaped in such a way that they have floor elements 32 .
- a substantially cuboid arrangement space A is formed. This is expediently used to accommodate as large a number of energy storage cells 40 as possible. In the present case, these are shown as round cells.
- the end sections 30 are each attached to the middle section 20 along a joining area or a joining plane F.
- This joining plane is expediently designed to be planar or flat. It is also present in the Substantially perpendicular to the plane of the drawing.

- the central portion 20 is formed as folded sheet metal.
- the advantageously cast end section 30 or its wall element 34 can be seen.
- the bending or folding has the particular advantage that the flange elements 26 have a good levelness. When deep-drawing structures of this type, the problem arises that the flange elements are too wavy. This entails problems when arranging the upper part of the housing, since the required tightness is generally not readily achievable.
- Fig. 3 shows the view B-B outlined in Fig. 1.
- a side view of the lower housing part 2 sketched in FIG. 1 is shown here schematically. It can be seen here in particular how the end sections 30 each form wall elements 34 or a base element 32 . It can be seen that the end sections 30 continue the geometry of the middle section 20, so to speak.
