- this vertical removal and simple disassembly of the battery packs 7 can be carried out either upwards in the vertical direction of the vehicle (z-direction) (for example in the case of a tractor unit as a commercial vehicle 10) or downwards in the vertical direction of the vehicle (z-direction) (for example in the case of a flatbed vehicle with fixed superstructures as a commercial vehicle 10).
- Figure 2 shows several alternative embodiments for forming energy packages 7 for the drive device of differently designed commercial vehicles 10.
- any number of energy modules 2, 3 can be combined in an energy module row 4, 5, 6 via a respective Support cage 25 can be connected to the chassis support structure 11 of the commercial vehicle 10.
- Any type of commercial vehicle 10 can be considered as commercial vehicles 10, for example tractor units with semitrailers or flatbed vehicles with fixed bodies.
- a total of six battery modules 2 are provided as energy modules for the drive device of the commercial vehicle 10, which is designed as a tractor unit, for example. These six battery modules 2 are divided into three battery packs 7 as energy packs in such a way that each of the battery packs 7 has two battery modules 2. Each of the battery packs 7 with the two battery modules 2 is connected to the chassis support structure 11 of the commercial vehicle 10 in a battery module row 4, 5, 6 via a respective receiving cage 25.
- This device 1 forms an installation space reserve 19, for example for accommodating electric auxiliary drives and/or mechanical auxiliary drives of the commercial vehicle 10.

- the device 1 for receiving energy modules 2, 3 or energy packages 7 is shown without the energy modules or without the energy packages for the sake of illustration.
- the “inside” is first formed from the two internal support brackets 8 arranged at the top and bottom by riveting them together with the two combined U/L profile supports 21. Inserts 9 made of aluminum and/or plastic, for example, are attached to the top 13 of these inner sides so that the energy modules 2, 3 to be attached do not rub against the rivet heads.
- a thrust plate 15 is provided on each of the two end faces of an energy module 2, 3. Such thrust plates 15 are therefore also present on the two end faces 26 of a receiving cage 25.
- the thrust plates 15 are preferably designed like a lattice, i.e. they have a specific lattice structure.
- the "inner wall” formed on the "inside” is pushed onto the energy modules 2, 3 or onto the inner support brackets 8 and these are screwed to the screw points 22. In the vertical direction of the vehicle (z direction), no space is therefore required as installation space beyond the material thickness of the components.
- the two support brackets 8 are then placed on the outside and these are screwed to the energy modules 2, 3.
- the two thrust plates 15 of an energy module 2, 3, which are designed as identical parts, are thus connected to one another in the longitudinal direction of the vehicle (x-direction) via the support angles 8 at all four corners. This not only supports the thrust plates 15 and thus the energy packages 7 in the transverse direction of the vehicle (y-direction), but also increases the shear stiffness in the longitudinal direction of the vehicle (x-direction).
- a receiving cage 25 for receiving the energy modules 2, 3 of an energy package 7 is thus formed from the four support angles 8 in the vehicle's longitudinal direction (x-direction) and from the two thrust plates 15 on the end faces 26, which additionally has further thrust plates between the individual energy modules 2, 3 of the energy package 7.
- the thrust plates 15 in the two outer battery module rows 4, 6 located on the outside of the commercial vehicle 10 are designed such that Crash elements for the commercial vehicle 10 can be connected to the outside and/or the side paneling of the commercial vehicle 10 can be connected.
- the two-part cross member 16, 17 with two brackets and a bridge provides a cross connection of the thrust plates 15 in the various battery module rows 4, 5, 6 and thus further stabilizes the device 1 in the transverse direction of the vehicle (y-direction).
- the support cages 25, which are placed on the chassis support structure 11 of the commercial vehicle 10 on the support brackets 14 attached there, with the energy packages 7 integrated therein, are screwed to the two-part cross member 16, 17 at the screw points 22 in the vehicle's vertical direction (z-direction) and at the screw points 23 in the vehicle's longitudinal direction (x-direction).
- a platform element 18 is provided for connecting the two outer energy module rows 4, 6.
- This platform element 18 can be designed to accommodate and/or connect electronic components or other parts or components of the commercial vehicle 10.
- the platform element 18 is designed as a hat profile, which is connected in a flexible manner to the two receiving cages 25 for the energy packages 7 in the two outer energy module rows 4, 6. This provides transverse support for the device 1, which prevents overloading of the receiving brackets 14, but allows twisting of the chassis support structure 11.
