- the arrangement which corresponds to an arrangement of energy storage cells modeled on the honeycomb, has the advantage of efficient use of installation space. In spite of this, such an arrangement offers enough space between the individual energy storage cells for cooling the cells by means of a fluid, for example.
- this generic device has the advantage that the definition of the cell arrangement can be produced inexpensively.
- the carrier plate has interconnected external hexagonally shaped partial receptacles, each partial receptacle having such an inner contour that is dimensioned for non-positive and / or positive holding of an energy storage cell.
- At least one or more partial receptacles is / are connected on the outside with at least one or more similar partial receptacles - here, a wall of a partial receptacle is brought into contact with a wall of an adjacent partial receptacle. This ensures a space-efficient structure.
- the partial receptacle has at least one axial position limiter for the energy storage cell, which is oriented so that it comes into contact with the end face of the energy storage cell or adjacent to the end face of the in the state in which the energy storage cell is inserted into the carrier plate Energy storage cell is arranged.

It is preferred here if the formed frames of the contact plate correspond in shape and size to the partial receptacles of the carrier plate.
- a contact web is designed as a web-like connec tion between two opposite corners of the hexagonally shaped frame mens. This has the advantage, among other things, that the contact web serves, on the one hand, as electrical contact with the energy storage cell and, on the other hand, that the contact web formed in this way gives the hexagonally shaped frame stability.
- the axial position limiters of a partial receptacle converge and define a spacing area between them which is exactly covered or filled by a contact web of a hexagonally shaped frame of the axial contact plate. In other words, this means that the width of the con tact web corresponds to less than 1/5 of the length of an unwound axial position limiter.
- the thickness of the contact web measured in the axial direction corresponds, preferably exactly, to the thickness of the axial position limiter measured in the axial direction.
- the carrier plate is provided as a support body for receiving the plurality of energy storage cells and is designed in plate form, preferably by plastic injection molding or compression molding.

- a contact plate is produced to match the carrier plate, also as a plate, for example in a stamping / or forming process.
- the at least one contact plate is clamped in a form-fitting manner or non-positively connected to the at least one carrier plate.
- a sewing / bandaging process in the present application is to be understood as a process in which the at least one contact plate is connected to the at least one carrier plate in such a way that it resembles sewing or bandaging generally known from the textile sector.
- this process describes the joining of materials, of the same or different types, by a seam, which has the advantage that seam connections are considered to be very stable and resilient.
- the composite of the at least one contact sheet with the at least one carrier plate is designed to adapt the shape and size along the honeycomb-like structure, preferably flexibly, to a shape and size corresponding to a purpose.
- the geometric configuration of the body can be optimized for a later, flexible shaping of energy storage cell bundles by shearing and / or sawing. Accordingly, the contact elements / energy storage cell poles and the contact sheet can be contacted with one another.
- the positive-pole contact elements of the plurality of energy storage cells by joining, in particular welding, or a process based on the sewing / taping process of a stator or rotor winding head, with a first contact sheet and the negative-pole contact elements of the plurality on energy storage cells by joining, in particular welding, or a process based on the sewing / taping process of a stator or rotor winding head, connected to a second contact sheet.
- the “+” and “-” sides of the individual energy storage cells to be accommodated can be connected either by joining, such as welding, of the pole / contact element and the contact sheet, or by a process similar to sewing.
- the first contact plate is arranged opposite the second contact plate.
- the invention also relates to a battery pack or an “InED battery pack” with an energy storage cell receptacle according to one of the above aspects, where the first and second contact plate each have the upper and lower outside of a battery pack made up of two receiving devices and a plurality arranged in between Forms energy storage cells.
- the battery pack is constructed in the following order of a first contact plate on the underside, a first carrier plate, a plurality of energy storage cells, then a second carrier plate and then a second contact plate on the top.
- a central hole is arranged in the center of a contact web, which is dimensioned such that a contact element of one of the plurality of energy storage cells engages, preferably positively and / or non-positively, when the battery pack is completed.
- the half thickness of the energy storage cell receptacle measured in the axial direction is less than a third of the thickness or height of an energy storage cell measured in the axial direction.
- the hexagonal lattice structure made of preferably reinforced plastic is used to hold or fix a plurality of cylindrical energy storage cells, in particular 18650 or 21700, and the associated, geometrically similar / identical, electrically conductive contact plate as a common connection of the energy storage cells with the respective to the pulse or negative pole.
- the modular, interlinkable concept thus allows a high degree of flexibility of the outer geometric contour or the border of the energy storage cell or the cell holder or the cell unit.
- an arrangement that is protected against polarity reversal results from an identically aligned grouping of the energy storage cells.
- the invention also relates to a method for producing a battery pack according to the above aspects with regard to the battery pack, at least one carrier plate being injection-molded, preferably plastic injection-molded or compression-molded, at least one contact plate being punched or reshaped and both the carrier plate as well as the contact plate is formed by a honeycomb-like structure for receiving the plurality of energy storage cells.
- the present invention thus offers a high degree of flexibility in the shaping of the later energy storage cell bundles with, at the same time, very good control of the tolerances in all spatial directions.
- the optimized geometry also offers the option of standardizing the basic components. This has the advantage of lower costs in the value chain.
