Definitions
- the invention relates to an arrangement of an electrical energy storage device on a bodyshell for a passenger car, according to the preamble of claim 1.
- the invention further relates to a passenger car and an electrical energy storage device.
- the US 2020/0324827 A1 discloses a floor structure for a vehicle, with a main floor which has an opening. Furthermore, from the
- DE 10 2020 101 679 A1 discloses a battery housing for a traction battery of an electrically driven motor vehicle.
- the object of the present invention is to create an arrangement of an electrical energy storage on a bodyshell for a passenger car, a passenger car and an electrical energy storage, so that a particularly advantageous connection of the electrical energy storage to the bodyshell and a particularly high energy content of the electrical energy storage as well as Particularly good protection of the electrical energy storage can be achieved with relatively low operating costs at the same time.
- the fully assembled or manufactured and in particular tested electrical energy storage device is mounted on the shell using screws and/or using at least one or more adhesive connections.
- the adhesive connection seals the vehicle all around against the ingress of moisture.
- the adhesive connection has completely or at least partially sealing and strength functions.
- the side sills limit a through opening in the transverse direction of the vehicle to the outside on both sides, in particular directly.
- the through opening extends uninterrupted from side sill to side sill and thus over the entire gap arranged between the side sills in the transverse direction of the vehicle.
- the side sills are connected to one another by at least one or more transverse elements, it being preferably provided that the respective transverse element is part of the bodyshell.
- the respective cross element can be a seat cross member. Since the entire main floor is formed entirely by the housing cover, no floor element of the bodyshell is arranged in the vertical direction of the vehicle between the housing cover and the transverse elements, which are designed in particular as cross members.
- the through opening ends, for example, in the longitudinal direction of the vehicle towards the rear at a rear floor, which is part of the bodyshell.
- a seat system of the passenger car which is designed in particular as a rear seat and is arranged in a rear area of the interior, is arranged over the rear floor.
- the opening is completely overlapped by the housing cover and is therefore closed.
- the housing also known as a storage housing, is inserted as a whole into the shell, in particular into the through opening, with the housing cover forming the entire main base.
- the invention makes it possible to produce the shell and the electrical energy storage independently of one another and to certify them independently of one another, although the invention provides for a high integration concept within its framework the electrical energy storage is integrated into the shell.
- tolerance requirements for the electrical energy storage in the bodyshell can be reduced.
- This allows a particularly long electric range of the passenger car to be achieved.
- tolerances and structural component reserves can also be reduced there compared to conventional solutions, so that a particularly large installation space can be created, for example, for accommodating storage cells for storing electrical energy, in particular electrochemically.
- the degassing channels are formed, in particular directly delimited, by a zigzag-shaped or wave-shaped component, in particular of the lower part. Due to the component, the memory cells are overlapped downwards, in particular completely, in the vertical direction of the passenger car, also known as a vehicle.
- the component has at least a dual function. On the one hand, the component is used to form the degassing channels.
- the housing cover has a frame with lateral energy absorption elements, each of which has a plurality of hollow chambers.
- the storage cells are at least on both sides in the transverse direction of the vehicle towards the outside through the energy absorption elements partially overlapped.
- the energy absorption elements can advantageously absorb accident-related loads acting in the transverse direction of the vehicle from the outside to the inside and thus in the direction of the storage cells, which means that the storage cells can be protected in a space- and weight-efficient manner.
- FIG. 2 shows a schematic representation of a sequence of a method for producing the arrangement according to the invention
- 5 shows a detail of a schematic and sectioned perspective view of the arrangement
- 6 shows a detail of a schematic cross-sectional view through a component of the energy storage device
- FIG. 8 shows a schematic top view of storage cells of the energy storage according to a second embodiment
- FIG. 9 shows a detail of a schematic perspective view of a protective structure of the energy storage device, also referred to as a replacement structure
- FIG. 10 shows a detail of a schematic cross-sectional view through the energy storage in the event of a thermal event
- FIG. 11 shows a schematic and perspective top view of a lower part of the energy storage during the thermal event.
- Fig. 12 shows a detail of another schematic cross-sectional view through the energy storage.
- the electrical energy storage 10 is also referred to as a battery or traction battery or is designed as a battery, in particular as a traction battery.
- the electrical energy storage 10 is a high-voltage component with an electrical voltage of several 100 volts.
- the bodyshell 12 has two side skirts 14 spaced apart from one another in the transverse direction of the vehicle, between which a main floor 16 extends.
- the vehicle transverse direction is illustrated in FIG. 1 by a double arrow 18 and is also referred to as y or y-direction in the vehicle coordinate system.
- the side skirts 14 in the transverse direction of the vehicle outwards on both sides and directly delimit a through opening 20 of the bodyshell 12, which extends backwards in the longitudinal direction of the vehicle up to a rear floor 22 of the bodyshell 12.
- the longitudinal direction of the vehicle is through a double arrow 24 illustrates and is also referred to as the x direction in the vehicle coordinate system or x.
- a seating system of the passenger car When the passenger car is fully manufactured, a seating system of the passenger car, designed for example as a bench, is arranged in the vertical direction of the vehicle above the rear floor 22, the seating system being arranged, for example, in a rear area of the interior of the passenger car and thus providing at least one or more seats for rear passengers of the passenger car.
- the vehicle vertical direction is illustrated by a double arrow 26 and is also referred to as the z direction in the vehicle coordinate system or z.
- the through opening 20 extends in the transverse direction of the vehicle over the entire space arranged between the side sills 14 in the transverse direction of the vehicle and thus over more than half the width of the interior.
- the through opening 20, viewed in the longitudinal direction of the vehicle extends over more than the length of the interior, in particular continuously, that is, without interruption.
- the side sills 14 can be connected to one another by, for example, cross elements of the bodyshell 12 designed as cross members 28, the cross members 28 being connected, in particular directly, to the side sills 14.
- the cross members 28 are seat cross members, to which, for example, additional seating systems of the passenger car, in particular designed as individual seats, can be attached.
- the further seating systems are arranged in a rear area of the interior.
- the cross members 28 are therefore components of the shell 12.
- the entire main base 16 is exclusively and completely covered by a housing cover 29 of a housing 30, also referred to as a storage housing or battery housing, which is separate from the housing Shell 12 trained, electrical energy storage 10 is formed. Since the electrical energy storage 10 is designed separately from the shell 12, the housing 30 and thus the housing cover 29, also simply referred to as a cover, are also designed separately from the shell 12. Thus, the entire main floor 16, which completely overlaps and thus closes the entire through opening 20, is not part of the shell 12, which is therefore is free of a main floor.
- the entire main base 16 is completely formed by a cover part 32 of the housing cover 29, for example made of sheet metal, the cover part 32 preferably being formed in one piece, that is to say is formed from a single piece. Since the cover part 32 is preferably made of sheet metal, the cover part 32 is also referred to, for example, as a cover plate. Thus, for example, the cover plate completely forms the entire main base 16.
- the cover plate (cover part 32) is therefore a base plate forming the entire main floor 16, which, however, is not part of the shell 12, but is part of the energy storage 10, which is designed separately from the shell 12.
- a method for producing the arrangement is shown in a schematic representation in FIG.
- the shell 12 and the energy storage 10 are, for example, manufactured separately and independently of one another and in particular completely in a first step S1.
- the shell 12 and the energy storage 10 are connected to one another after their complete production, in particular in such a way that the energy storage 10 is joined to the shell 12.
- the housing cover 29 is inserted into the through opening 20, and for example, the housing cover 29 is connected, in particular directly, to the shell 12, in particular to the side sills 14, and thus fastened to the shell 12, in particular to the side sills 14.
- the energy storage device 10 in particular the housing cover 29, is glued and/or screwed to the shell 12, in particular to the side skirts 14.
- the energy storage 10 is therefore, for example, an integrated structural battery, although the shell 12 and the energy storage 10 are individual trades that can be manufactured independently of one another and, in particular, certified.
- the shell 12 and the energy storage 10 can be manufactured using existing production lines.
- the advantage over conventional methods is that at least almost all air gaps that have to be maintained in conventional solutions due to component tolerances and assembly clearances can be reduced to a minimum or at least partially avoided.
- This allows a particularly advantageous crash structure and a particularly large installation space to accommodate the energy storage 10 to be created.
- a particularly high level of safety for the passenger car and a high level of safety can be achieved Energy content of the energy storage 10 are shown, so that a particularly high electric range of the passenger car is possible.
- the energy storage 10 closes the shell 12 and forms the entire main base 16.
- conventional solutions only require minimal joining tolerances.
- An otherwise usual distance between a conventionally provided base plate of the shell 12 and the housing 30 can be omitted, although such a distance would have to be specially sealed and filled with noise insulation mats in order to achieve corrosion protection and to achieve advantageous noise behavior, which is no longer the case due to the arrangement according to the invention is required.
