Description

Housing device, energy storage system, motor vehicle and method for producing an energy storage system Technical Field The invention relates to a housing device for receiving a single-piece device. The invention also relates to an energy storage system comprising at least one housing device and at least one single device, a motor vehicle having an energy storage system and a method for producing an energy storage system. Background In the prior art, housing devices for receiving a cell device are known to date, in which the cell device is clamped in a separate, fixed frame in order to compensate for cell expansion, for example to prevent reversible expansion during charging and discharging and/or to prevent continuous expansion due to aging of the cell device. The known frames are usually designed as sheet metal holders and/or as extruded structures for the individual devices between aluminum die castings or extruded profiles. The single-body device is usually pretensioned with a certain pressure and exerts a large force on the carrier structure and/or the frame structure during operation. As a result, the support structure and/or the frame structure are often embodied to be very rigid and/or stable, which often results in increased material costs, weight costs, cost costs and/or component costs. The known solutions have the disadvantage that the individual devices are often installed inside a rigid carrier frame, for example using metal elements which, due to the base material, bring about a large weight and are furthermore connected to one another by a plurality of assembly steps. Additional effort is made due to the electrical conductivity of the metal in order to ensure insulation of the cell arrangement, for example by winding the lithium ion cell with a film and/or by adhering an insulating film to the metal element. Disclosure of Invention It is therefore an object of the present invention to obviate or at least partially eliminate the above-mentioned disadvantages of the prior art. The object of the invention is, in particular, to provide a housing device by means of which a receiving unit can be realized in a particularly simple manner. The object of the invention is, in particular, to provide an energy storage system, a motor vehicle and a method for producing the same. The above-mentioned task is solved by the claims. In particular, this object is achieved by a housing arrangement having the features of independent claim 1. The object is also achieved by an energy storage system having the features of independent claim 13, by a motor vehicle having the features of independent claim 14 and by a method for producing a motor vehicle having the features of independent claim 15. Further advantages and details of the invention result from the dependent claims, the description and the figures. The features described in connection with the housing arrangement according to the invention are of course also applicable here in connection with the energy storage system according to the invention, the motor vehicle according to the invention, the method of manufacture according to the invention and vice versa, respectively, so that the disclosure concerning the individual inventive aspects is always or can be referred to each other. According to a first aspect of the invention, the object is achieved by a housing arrangement for receiving a cell arrangement for storing electrical energy for a motor vehicle, having a base body and a receiving volume for receiving the cell arrangement at least partially within the base body, wherein the base body comprises at least one inner side facing the receiving volume and at least one outer side facing away from the receiving volume, wherein the base body has at least two opposing main rib arrangements on the at least one outer side for structurally reinforcing the housing arrangement, wherein the base body has at least one tool recess on the at least one inner side for each of the at least two opposing main rib arrangements, wherein the at least two tool recesses are designed for the engagement of a tool for the joint introduction of the cell arrangement into the receiving volume, wherein the base body, the at least two opposing main rib arrangements and the at least two tool recesses are designed as one piece. The base body is preferably made of plastic. The housing means advantageously enables a very rigid housing for receiving the monomer means. The advantageous structural properties of the housing arrangement are achieved primarily by the outer ribs in the form of the at least two opposing main rib arrangements. In addition to the structurally advantageous properties, the rib arrangement also enables good material distribution for producing the housing arrangement, for example in an injection mold. As explained in detail below, the rib means are designed on the housing means in the direction of extrusion of the cell means and/or in the direction of extrusion of the ce
