[0279] For example, as illustrated in Fig. 3, the position adjustment element 124 and / or the compensation element 126 can be arranged at one end 130 of the arrangement zone 110. In particular, the position adjustment element 124 and / or the compensation element 126 can be arranged at the end 130 of the arrangement zone 110 such that an end face 132 of the energy storage element 102 can come into contact with the position adjustment element 124 and / or the compensation element 126 after the energy storage element 102 has been inserted into the arrangement zone 110.

[0280] Fig. 3 also indicates that the energy storage element 102 has a shell surface 134 that extends from one end face 132 to the other end face 132.

[0281] It can be advantageous if the position adjustment element 124 and / or the compensation element 126 is elastic and / or consists partly or completely of an elastic material 136 and / or is made partly or completely of an elastic material 136.

[0282] The unit 108 has, in particular, an inner surface 138. The inner surface 138 is a surface 140 of the unit 108 facing the arrangement zone 110.

[0283] The inner surface 138 bounds the arrangement zone 110 externally, particularly in the radial direction. The inner surface 138 is a ring-shaped, particularly cylindrical, surface 140 of the unit 108 extending around the arrangement zone 110. The energy storage element 102 can be inserted into the arrangement zone 110 in an insertion direction 142 along the inner surface 138 of the unit 108.

[0284] For example, the arrangement zone 110 can have two offset ends 130 of the arrangement zone 110 in which the two ends 144 of the energy storage element 102 that can be fixed in the arrangement zone 110 can be positioned.

[0285] As can be clearly seen, for example, in Fig. 1, the unit 108 can have an arrangement section 146 that extends in a ring-shaped and hollow-cylindrical form around the arrangement zone 110. The arrangement section 146 has the inner surface 138 of the unit 108.

[0286] When the energy storage element 102 is fixed to the unit 108 in the arrangement zone 110, the energy storage element 102 is also arranged in the arrangement section 146.

[0287] The unit 108 can, for example, have a shell element 148 which is hollow cylindrical, wherein the arrangement zone 110 extends into and is located within the shell element 148. The arrangement section 146 is formed by the shell element 148.

[0288] When the energy storage element 102 is fixed to the unit 108 in the arrangement zone 110, the energy storage element 102 is arranged in the casing element 148.

[0289] The sleeve element 148 can, for example, be a sleeve element 150, which can be made of metal or plastic.

[0290] It can be advantageous if the fixing element 112, which is shown only schematically in Fig. 2 and also in other figures, is formed, arranged and / or attachable to the arrangement section 146 and / or to the sleeve element 148, for example to the sleeve element 150.

[0291] It can be advantageous if the fixing element 112 extends, as shown in particular in Fig. 10, from the arrangement section 146 and / or from the shell element 148, for example from the sleeve element 150, from an edge 152 of the arrangement section 146 and / or the shell element 148, e.g. of the sleeve element 150.

[0292] It can be advantageous if an insulating material 154 is arranged on an inner surface 138 of the unit 108 (Fig. 4). Alternatively or additionally, an insulating material 154 can be arranged on an outer surface 156 of the unit 108 (Fig. 5). The insulating material 154 can preferably form an insulating layer 158 on the inner surface 138 and / or on the outer surface 156.

[0293] As described in document DE 102014 112 596 A1, the insulating layer 158 can be formed from a liquid sealant.

[0294] Alternatively, the arrangement section 146, the casing element 148, for example the sleeve element 150, can be made entirely or partially from a sealant described in document DE 102014 112 596 A1.

[0295] Figures 6 and 7 illustrate that the fixing element 112 or another fixing element 112 can be a protrusion 160 present on an inner surface 138 of the unit 108, wherein the inner surface 138 can, for example, be a surface 140 of the unit 108 facing the arrangement zone 110.

[0296] For example, the energy storage element 102 can be fixed to the unit 108 in the arrangement zone 110 by means of the elevation 160.

[0297] The elevation can preferably be one of several, preferably at least three, elevations 160 spaced apart from each other on the inner surface 138.

[0298] It may be advantageous if the energy storage element 102 can be fixed to the unit 108 in the arrangement zone 110 by means of the protrusion 160, by means of the protrusions 160 and / or between the protrusions 160.

[0299] It can be advantageous if at least two of the projections 160, preferably at least three of the projections 160, are spaced apart from each other in a circumferential direction 174 on the inner surface 138. It can be advantageous if at least two of the projections 160 are formed from or coated with an adhesion-enhancing and / or elastic material 176, wherein the adhesion-enhancing and / or elastic material can, for example, comprise a natural rubber, a partially or entirely synthetic rubber, and / or an elastomer.

[0300] Fig. 8 shows a system 100 for positioning and / or electrically contacting several energy storage elements 102, which differs from the systems shown in Fig. 1 and Fig. 3, particularly with regard to electrical contacting.

[0301] The positioning and / or electrical contacting systems 100 shown in Figs. 1 and 3 each have a positioning system 166 and a contacting system 162.

[0302] Figures 1 and 3 clearly show that there is no direct connection between the contacting element 168 of the contacting system 162 and the unit 108. Only when the energy storage element 102 is fixed to the unit 108 in the arrangement zone 110 does an indirect connection between the contacting element 168 and the unit 108 arise via the energy storage element 102.

[0303] In the systems 100 shown in Figs. 1 and 3, the unit 108 described in connection with these systems does not have any of the contact zones 170 between which the contact elements 168 extend from one energy storage element to the next nearest energy storage element.

[0304] The system 100 shown in Fig. 8 for positioning and / or electrically contacting several energy storage elements 102 is a system 164 for positioning and electrically contacting several energy storage elements 102. The unit 108 has a contact zone 170 for establishing electrical contact between the unit 108 and one of the electrical poles 172 of the energy storage element 102, which can be fixed in the arrangement zone 110. The contact zone 170 shown in Fig. 8 is arranged and configured to establish electrical contact by bearing and / or pressing one of the electrical poles 172 against the contact zone 170.

[0305] The contact zone 170 is arranged and designed to produce the electrical contact without material contact.

[0306] The contacting zone 170 is arranged and designed to produce the electrical contact without conductive material.

[0307] The contact zone 170 is arranged and designed to produce the electrical contact without a welded connection.

[0308] The contact zone 170 is arranged and designed to produce the electrical contact without solder.

[0309] The contact zone 170 is arranged and designed to produce the electrical contact without electrically conductive adhesive.

[0310] For example, the electrical contact of the unit 108 to one of the electrical poles 172 of the energy storage element 102, which can be fixed in the arrangement zone 110, can be reinforced and / or stabilized by means of the fixing element 112. This becomes clear, for example, from the combined view of Figures 2 and 8. Thus, for example, the contact zone 170 can be formed on the fixing element 112, and the fixing element 112, during or after a forming of the fixing element 112, with its contact zone 170, can come to rest on one of the electrical poles 172 of the energy storage element 102, which can be fixed in the arrangement zone 110.

[0311] Advantageously, one of the electrical poles 172 of the energy storage element 102 can be pressed onto the contact zone 170 by means of the fixing element 112.

[0312] Fig. 8 shows that the unit 108 for positioning and / or electrically contacting one of the energy storage elements 102 is a first unit 178 for positioning and / or electrically contacting a first energy storage element 180 of the energy storage elements 102. The arrangement zone 110 is a first arrangement zone 182, and the first energy storage element 180 can be fixed to the first unit 178 in the first arrangement zone 182.

[0313] The system 100 shown in Fig. 8 comprises a second unit 188 for positioning and / or electrically contacting a second energy storage element 190 of the energy storage elements 102. The second unit 188 has a second arrangement zone 192, wherein the second energy storage element 190 can be fixed to the second unit 188 in the second arrangement zone 192.

[0314] Unit 108 has an electrically conductive contact element 168 which is electrically connected to contact zone 170. Unit 108 is the first unit 178. Contact zone 170 is a first contact zone 194, wherein the first unit 178 has the first contact zone 194. The electrically conductive contact element 168 is a first contact element 196 which is electrically connected to the first contact zone 194.

[0315] Fig. 9 also shows a system 100 for positioning and / or electrically contacting several energy storage elements 102, wherein the system 100 is a system 164 for positioning and electrically contacting several energy storage elements 102.

[0316] Figure 9 shows a section of the system 100, comprising five units 108 for positioning and / or electrically contacting one of the energy storage elements 102 each. Each unit 108 has an electrically conductive contacting element 168. Each unit 108 has a contacting zone 170 for establishing electrical contact between the unit 108 and one of the electrical poles 172 of the energy storage element 102, which can be positioned in the respective arrangement zone 110 of the respective unit 108.

[0317] In each of the units 108 shown in Fig. 9, its electrically conductive contact element 168 is electrically connected to its contact zone 170. For example, the unit 108 shown on the far left in Fig. 9 can be considered a first unit 178 for positioning and / or electrically contacting a first energy storage element 180 of the energy storage elements 102.

[0318] In particular, the unit 108, which is shown in the second position from the left in Fig. 9, can then be understood as a second unit 188 for positioning and / or electrically contacting a second energy storage element 190 of the energy storage elements 102.

[0319] The contact zone 170 of the unit shown on the far left in Fig. 9 is then a first contact zone 194. The electrically conductive contact element 168 of the unit shown on the far left in Fig. 9 is then a first contact element 196 electrically connected to the first contact zone 194.

[0320] The electrically conductive contact elements 168 shown in Fig. 9 each have a contact section 198. In Figs. 9 and 10, selected contact sections 198 are highlighted with dotted lines.

[0321] The contact sections 198 can each be used for contacting another unit or another energy storage element.

[0322] Fig. 10 shows a unit 108. With the unit 108 shown in Fig. 10, a system 100, shown in Fig. 9, can be constructed, wherein several of the units 108 shown in Fig. 10 are arranged relative to each other as shown in Fig. 9.

[0323] In the unit 108 shown in Fig. 10, the contacting section 198 of the contacting element 168 is not arranged opposite the fixing element 112, but merely offset in a circumferential direction 174 from the fixing element 112. To construct the system shown in Fig. 9, a slightly modified unit 108 can be used instead of the unit 108 shown in Fig. 10, in which the contacting section 198 is located opposite the fixing element 112.

[0324] In the unit 108 shown in Fig. 10, it is possible that the unit, in particular the casing element 148, e.g. the sleeve element 150, is made of an electrically conductive material. In particular, the contacting element 168 can then be electrically connected to the contacting zone 170 via the arrangement section 146, the casing element 148 or the sleeve element 150 itself.

[0325] Alternatively, the electrically conductive contact element 168 can be electrically connected to the contact zone 170 by means of a conductive element 200, which is indicated by a dashed line in Fig. 10. This is particularly advantageous if the unit 108, especially the casing element 148, e.g., the sleeve element 150, is made of a plastic that is not itself electrically conductive.

[0326] In the units 108 shown in Fig. 9, the contacting section 198 extends from a zone 202 of the respective unit 108, wherein the zone 202, from which the respective contacting section 198 extends, is not offset from the contacting zone 170 of the same unit 108 along an axis 204, along which the energy storage element 102 can be inserted into the respective arrangement zone 110. Such arrangements of contacting element 168 and contacting zone 170 at the same end of the arrangement zone are particularly suitable for contacting energy storage elements 102 in which the two contacts or electrical poles, via which electrical energy can be drawn from the energy storage element, are arranged at the same end of the energy storage element.

[0327] Alternatively, an offset of zone 202, from which the contacting section 198 extends, relative to the contacting zone 170 along axis 204 would be conceivable in order to enable contacting of an energy storage element 102 in which the two contacts or electrical poles, via which electrical energy can be extracted from the energy storage element, are arranged at different ends of the energy storage element 102.

[0328] The units shown in Figures 8, 9 and 10 have insulation 206. For example, a unit 108 can have the insulation 206, as shown for example in Figures 8, 9 and 10, at an edge region 208 of the unit 108.

[0329] For example, as illustrated in Fig. 8, the second unit 188 can have insulation 206. The insulation 206 can be located, in particular, on an edge zone 208 of the second unit 188. The insulation 206 prevents electrical contact between the second unit and the first contacting element 196, which can be guided along the edge zone 208 of the second unit 188. It is clearly visible in Figs. 8 to 10 that the edge zone 208 is located on an edge 152 of the assembly section 146 and the sleeve element 148, e.g., the sleeve element 150. The edge zone can also be located on an outer surface 210 of the fixing element 112, as can also be seen in Figs. 8 to 10.

[0330] In the units 108 shown in Figures 11, 12, and 13 for systems 100 for positioning and / or electrically contacting energy storage elements, the arrangement zones 110 each extend from one end 130 of the arrangement zone to another end 130 of the arrangement zone. In the units 108 shown there, one of the ends 130 of the arrangement zone 110, which is shown at the top in Figures 11, 12, and 13, forms a contact end 212 of the respective arrangement zone 110. Another end 130 of the arrangement zone 110 shown there, which is shown at the bottom in Figures 11, 12, and 13, forms a fixing end 214.

[0331] Each contact end 212 has at least one contact zone and / or at least one contact element. In Figures 11 to 13, the contact zones and / or contact elements are not shown or are not labeled.

[0332] The locking element 112 is arranged and / or formed at the locking ends 214 of the arrangement zones 110 in the units 108 shown in Figures 11 to 13. Figure 11 shows the locking element 112 in an open state 114, which is also a release state 118. Figures 12 and 13 show the locking element 112 in a closed state 116, which is also a locking state 120.

[0333] In the units 108 shown in Figures 11 to 13, the fixing end 214 is also an exchange end through which the energy storage element 102 can be inserted into and removed from the arrangement zone 110. Figure 14 shows a system 100 for positioning and / or electrically contacting several energy storage elements 102. The system 100 shown there is a system 164 for positioning and electrically contacting several energy storage elements 102.

[0334] In the system shown in Fig. 14, the electrically conductive contacting element 168 has a neighboring contacting zone 218 for producing an electrical neighboring contact of a unit 108, e.g. the first unit 178, to one of the electrical poles of an energy storage element 102, e.g. second energy storage element 190, which can be defined in a neighboring arrangement zone, e.g. the second arrangement zone 192.

[0335] The neighboring contact zone 218 is arranged and designed to establish the electrical neighboring contact by contacting and / or pressing one of the electrical poles of the energy storage element 102, e.g., the second energy storage element 190, which can be defined in the neighboring arrangement zone, against the neighboring contact zone 218.

[0336] The adjacent contact zone is arranged and designed to produce the electrical adjacent contact without material connection and / or conductive joining material, in particular without welding, without solder and without electrically conductive adhesive.

[0337] The adjacent contact zone is arranged and designed to create an electrical adjacent contact to one of the electrical poles that can be detached without damage and / or without tools.

[0338] This differs from the structure shown in Fig. 8, in which welding zones 222 are provided for contacting adjacent energy storage elements.

[0339] The system 100 shown in Fig. 15 for positioning and / or electrically contacting several energy storage elements 102 is also a system 164 for positioning and electrically contacting several energy storage elements 102. Units 108 of the system 100 shown in Fig. 15 each have a contacting aid element 220 for establishing an electrical contact between the respective unit 108 and one of the electrical poles 172 of the energy storage element 102 that can be fixed in the arrangement zone 110 of the respective unit 108.

[0340] A contact zone 170, which essentially corresponds to the contact zone 170 already described in connection with Fig. 8, is a contact zone 170 for establishing electrical contact between the respective unit 108 and one of the electrical poles of the energy storage element that can be defined in the arrangement zone. The contacting aid element 220 is a contacting aid element 220 for establishing electrical contact between the respective unit and the other of the electrical poles 172 of the energy storage element 102 that can be defined in the arrangement zone.

[0341] Advantageously, the contacting zone 170 can be used to contact one of the electrical poles and the contacting aid element 220 can be used to contact the other of the electrical poles of the same energy storage element.

[0342] As can be clearly seen in Fig. 15, one unit 108 of the system shown therein has the contacting element 168, and another unit 108 of the system 100 has the contacting aid element 220, wherein the contacting element 168 and the contacting aid element 220 are connected to each other directly or indirectly via an electrical conductor. In the example shown in Fig. 15, the contacting element 168 and the contacting aid element are connected to each other via an electrical conductor through a weld zone 222.

[0343] A contacting aid element 220 shown in Fig. 15 can extend transversely to the axis 204, along which an energy storage element can be inserted into an arrangement zone.

[0344] For example, a contacting aid element 220 shown in Fig. 15 can extend to an edge zone 208 of the unit 108.

[0345] A contacting aid element shown in Fig. 15 can be electrically insulated from the edge zone 208, for example, by the insulating element 206. A contacting aid element shown in Fig. 15 can be fixed to the edge zone 208 of the unit 108, for example, by means of an electrically insulating connecting element.

[0346] In the system shown in Fig. 16, a unit 108 has an electrically conductive contact element 168, which is electrically connected to the contact zone 170. The unit 108 also has an arrangement section 146, which extends annularly and hollow-cylindrically around the arrangement zone 110. The contact element 168 has a contacting section 198, which has already been described in more detail, particularly in connection with Figs. 9 and 10. The arrangement section 146 and the contacting section are formed integrally from an electrically conductive material 224, which can, for example, be a metallic material 226. In the example shown in Fig. 16, the electrically conductive material extends to the contact zone 170 and into the fixing element 112.

[0347] In the system 100 shown in Fig. 17, the unit 108 has a temperature control zone 230 for temperature control of the energy storage element 102, which can be positioned in the arrangement zone 110. It can be clearly seen in Fig. 17 that the temperature control zone 230 is closed off from the arrangement zone 110, so that a temperature control fluid can be guided in the temperature control zone 230 at a distance from the surface of the energy storage element 102.

[0348] All systems 100 shown in Figs. 1, 3, 8, 9, 14, 15, 16 and 17 have several units 108 for positioning and / or electrically contacting each of an energy storage element 102, including the first unit 178 described herein, the second unit 188 described herein and further units 108 which can be considered as the third, fourth, fifth, etc. unit.

[0349] The units 108, 178, 188 are arranged in or on a support element 234. In particular, the units 108, 178, 188 can be arranged in or on the support element in a regular pattern relative to each other.

[0350] In the system shown in Fig. 18, the support element 234 defines a temperature control area 232. Temperature control zones 230 are each fluid-conductingly connected to the temperature control area 232. One end 130 of each arrangement zone 110 extends into the temperature control area 232.

[0351] The contacting element 168 can, for example, be located in the temperature control area. This can, in particular, enable immersion cooling in the cell contacting area.

[0352] In Fig. 18, different temperature control options are shown side by side for illustrative purposes only.

[0353] Figures 1 to 18 show systems and units with energy storage elements. Only Figure 10 shows a unit 108 without an energy storage element 102 fixed in its arrangement zone 110.

[0354] Therefore, in addition to the systems for positioning and / or electrically contacting multiple energy storage elements described above, the figures also show energy storage arrangements 240. The energy storage arrangements 240 include the systems 100 described in detail up to this point and the energy storage elements defined in the arrangement zones.

[0355] Figure 2, in particular, illustrates a method for extending the operational readiness of an energy storage arrangement 240. The method involves replacing an energy storage element 102 fixed in an arrangement zone 110. Starting from the state shown on the right in Figure 2, one or more fixing elements 112 can, for example, be transferred from a closed state 116 and / or locking state 120 shown therein to an open state 114 and / or release state 118. This is illustrated by the transition from the right to the middle view in Figure 2. Subsequently, the energy storage element 102 can be removed (Figure 2, left view) and replaced by a new energy storage element 102.By transferring one or more locking elements 112 from the open state 114 and / or release state 118 to the closed state 116 and / or locking state 120, the new energy storage element 102 can be fixed in the arrangement zone 110 (Fig. 2, starting from the left illustration via the middle illustration to the right illustration).

[0356] This can be particularly advantageous because individual energy storage elements 102 can be replaced with minimal effort, so that if damage occurs in individual energy storage elements 102 that impairs the energy storage arrangement 240, it is not necessary to replace the entire energy storage arrangement 240, but only individual energy storage elements 102 can be replaced.

[0357] This can contribute to a significant extension of the operational readiness of an energy storage arrangement 240 with minimal effort.
