[0001] Energy storage system, positioning unit and fluid supply device

[0002] The present invention relates to the technical field of energy storage systems and associated components. It relates in particular to high-performance energy storage systems with which electrical energy can be provided for the propulsion of a motor vehicle.

[0003] Various proposals have been made to increase the efficiency and range of fully or partially electrically powered motor vehicles.

[0004] Efforts are underway to design the temperature control of electrochemical energy storage systems or energy storage modules, particularly their cooling, in such a way as to minimize energy consumption while simultaneously avoiding unnecessary increases in the vehicle's mass. This would allow a higher proportion of the energy storable in the energy storage unit to be made directly available for powering the lightest possible vehicle.

[0005] There are also efforts to provide electrochemical energy storage units or energy storage modules in the most compact designs possible, so that as much of the space as possible in a motor vehicle can be made available for occupants and / or goods to be transported.

[0006] Furthermore, the vehicle's center of gravity should be as low as possible, as this increases driving safety, especially when suddenly appearing obstacles have to be avoided at high speed.

[0007] Therefore, there is still a great need for improvement.

[0008] The present invention is based on the objective of providing an efficient energy storage system and / or a component thereof in the simplest possible manner. This objective is achieved according to the invention by an energy storage system as defined in the relevant independent claim.

[0009] The energy storage system comprises the following: an energy storage zone in which energy storage elements are arranged, a temperature control fluid system for temperature control of the energy storage elements, and an energy storage end zone extending to the ends of the energy storage elements, wherein the temperature control fluid system has a temperature control zone and the temperature control zone extends along or through the energy storage end zone.

[0010] It can be advantageous if end sections of the energy storage elements or a proportion of the energy storage elements are arranged in the energy storage end zone.

[0011] It is possible that the energy storage end zone extends into the energy storage zone. However, this is not a necessary requirement of the invention.

[0012] The energy storage system can be particularly advantageous in providing electrical energy for powering a motor vehicle.

[0013] The energy storage system can be particularly advantageous for storing electrical energy to power a motor vehicle.

[0014] The energy storage system can be particularly advantageous for storing electrical energy to power a motor vehicle.

[0017] Energy storage elements that can be arranged in the energy storage zone can be energy storage elements commonly used in energy storage systems for powering motor vehicles. These are generally known, which is why they will not be discussed in more detail here.

[0018] The energy storage elements, in particular the electrochemical energy storage elements, preferably the battery cells, especially preferably the rechargeable battery cells, for example the rechargeable lithium-ion battery cells, can be cylindrical or prismatic, in particular cylindrical.

[0020] The term "in particular" is used within the context of this description and the attached claims to describe possible optional and / or optional features.

[0021] The energy storage elements can be arranged in different ways within the energy storage zone.

[0022] It can be advantageous if the energy storage elements in the energy storage zone are arranged essentially parallel to each other.

[0023] Advantageously, energy storage elements that are closest to each other in the energy storage zone can be aligned essentially parallel to one another. "Aligned essentially parallel to one another" can, in particular, mean that the direction of extension of one energy storage element forms an angle of at most 15°, e.g., at most 5°, with the direction of extension of the next nearest energy storage element. The direction of extension of an energy storage element preferably runs along a central longitudinal axis of the energy storage element, which connects both ends of the energy storage element and passes through its center.

[0024] It can be advantageous if each energy storage element in the energy storage zone is essentially aligned parallel to the six nearest energy storage elements.

[0025] Such non-parallel alignments of energy storage elements in the energy storage zone can be particularly advantageous if the energy storage system and / or the energy storage zone does not have an exactly cuboid shape, for example due to the space requirements in a motor vehicle.

[0035] The temperature control zone extends along or through the energy storage end zone.

[0036] This can be particularly advantageous, as it allows the ends of the energy storage elements, to which the energy storage end zone extends, to be brought into heat transfer contact with a temperature control fluid that can be carried in the temperature control zone.

[0238] Identical or functionally equivalent elements are provided with the same reference symbols in all figures.

[0239] Fig. 1 shows a perspective view of an energy storage system 180. The energy storage system 180 shown there comprises two energy storage units 100.

[0240] The energy storage system 180 is an electrochemical energy storage system 182.

[0241] The two energy storage units 100 are energy storage modules 102. They are electrochemical energy storage units 104, which are electrochemical energy storage modules 106.

[0242] The energy storage system 180 shown in Fig. 1 has a

[0243] Temperature control fluid system 190. In the energy storage system 180 shown in Fig. 1, the energy storage unit 100 shown on the left has its own temperature control fluid system 190. In the energy storage system 180 shown in Fig. 1

[0244] The energy storage system 180 also includes the energy storage unit 100 shown on the right and a temperature control fluid guidance system 190.

[0245] The two temperature control fluid supply systems 190 each extend from an inlet unit 110 to an outlet unit 112 of the respective energy storage unit 100.

[0246] The energy storage system 180 shown in Fig. 1 has temperature control zones. The temperature control zones are each connected, either directly or indirectly, to one of the inlet units 110 and one of the outlet units 112 via a fluid-conducting connection.

[0247] The two energy storage units 100 each have an outer shell 108, which surrounds the temperature control zones that are hidden in Fig. 1 by the outer shell 108.

[0248] Fig. 2 shows another perspective view of the energy storage system 180, with the two outlet units 112 of the two energy storage units 100 facing the viewer.

[0249] The energy storage system 180 illustrated in Figures 1 and 2 has an energy storage zone 114 in which energy storage elements 116 are arranged. This is particularly evident from Figures 3 and 4, which each show one of the two energy storage units 100 depicted in Figures 1 and 2 in an exploded view and a partially opened view, respectively.

[0250] The temperature control fluid guidance system 190 can be used in particular for temperature control of the energy storage elements 116.

[0251] Fig. 3 also clearly shows that the outer shells 108 are made up of several outer shell elements 118.

[0252] Fig. 3 also shows that the energy storage system 180, in particular each energy storage unit 100, can have a contact arrangement 120, a propagation barrier 122, an intermediate barrier 124 and / or an intermediate layer 126.

[0253] In its assembled state, the contact arrangement 120 is positioned on the energy storage zone 114, particularly on the energy storage elements 116, such that the energy storage elements 116 are electrically contacted by the contact arrangement 120. The contact arrangement 120 comprises contacting elements 128. The propagation barrier 122 can, in particular, help to prevent the release of hot gases, or at least delay their release, in the event of thermal runaway of one of the energy storage elements 116. This, in particular, prevents uncontrolled heating of spatially adjacent energy storage elements in a neighboring energy storage unit 100.

[0254] In Fig. 3, dashed lines are shown. The dashed lines indicate the extent of the energy storage zone 114, in which the energy storage elements 116 shown in Fig. 4 are arranged.

[0255] A first energy storage zone extension 130 is measurable in a first direction 132.

[0256] A second energy storage zone extension 134 is measurable in a second direction 136.

[0257] A third energy storage zone extension 138 is measurable in a third direction 140.

[0258] In particular, it can be clearly seen from the figure that the first energy storage zone extent 130, measurable in the first direction 132, is larger than the second energy storage zone extent 134, measurable in the second direction 136.

[0259] The first direction 132 can be a principal extension direction 142. The first energy storage zone extension 130 measurable in the first direction 132, i.e., in the principal extension direction 142, can in particular be a length 144 of the energy storage zone 114.

[0260] The second energy storage zone extension 134, measurable in the second direction 136, can be a width 146 of the energy storage zone 114.

[0261] The energy storage elements 116, which can be seen in Fig. 4, have ends 148. In the representation shown in Fig. 4, the ends 148 of the energy storage elements 116 face the viewer. The energy storage system 180 has an energy storage end zone 150 that extends to the ends 148 of the energy storage elements 116.

[0262] The temperature control fluid guidance system 190 has a temperature control zone 152 which extends through the energy storage end zone 150.

[0263] The energy storage elements 116 are electrochemical energy storage elements 154. The energy storage elements 116 can be, for example, rechargeable battery cells 156, in particular cylindrical rechargeable battery cells 156.

[0264] Fig. 4 clearly shows that contact elements 128 of the contact arrangement 120 are located in the temperature control zone 152 and thus also in the energy storage end zone 150. The contact elements 128 of the contact arrangement extend through the temperature control zone 152 and thus also through the energy storage end zone 150.

[0265] Fig. 4 also shows that the temperature control zone 152 is limited in a direction 158 at least by a separation element 160 for one of the energy storage elements 116. The direction 158 is indicated by a dashed line in Fig. 4.

[0266] In the energy storage zone 114, which can be seen in Fig. 4, all energy storage elements 116 are aligned in parallel. The mean direction of extension 162 of the energy storage elements therefore corresponds to the direction of extension 158.

[0267] The energy storage system 180 has a passage 164 for supplying temperature control fluid to the temperature control zone 152. The passage 164 is a supply passage 166 for supplying temperature control fluid to the temperature control zone 152.

[0268] The energy storage system has a passage 168 for draining temperature control fluid from the temperature control zone 152. The passage 168 is a discharge passage 170 for draining temperature control fluid from the temperature control zone 152. The discharge passage 168 is offset relative to the supply passage 164 in the second direction 136. The offset 169 of the discharge passage 168 relative to the supply passage 164 is indicated by a double arrow in Fig. 4.

[0269] From the combined view of Figs. 3 and 4, it becomes clear that the offset 169 is almost the same size as the second energy storage zone extension 134.

[0270] Fig. 5 shows a section through the energy storage unit 100 shown in Fig. 4. The section shown in Fig. 5 was made along the dashed lines drawn in Fig. 4.

[0271] To improve clarity, certain aspects have been omitted from Fig. 5, while others have been added. For example, the energy storage elements 116 are not shown in Fig. 5. The contact arrangement 120 has also been omitted from Fig. 5. However, unlike Fig. 4, all outer sheath elements 118 are shown in Fig. 5.

[0272] Figure 5 shows that the energy storage system 180, in particular the energy storage unit 100 of the energy storage system 180 shown therein, has two energy storage end zones 150 and three temperature control zones 152. The energy storage end zone 150 already described in connection with Figure 4 is a first energy storage end zone 172. The ends 148 of the energy storage elements 116 described in connection with Figure 4 are first ends of the energy storage elements 116 not shown in Figure 5. However, in conjunction with Figure 4, it is clear that the first energy storage end zone 172 extends to the first ends of the energy storage elements 116.

[0273] The temperature control zone 152, which can be seen in Fig. 4, is a first temperature control zone 174 that extends through the first energy storage end zone 172.

[0274] An energy storage end zone 150, shown in Fig. 5 opposite the first energy storage end zone 172, is a second energy storage end zone 176. It extends to the second ends of the energy storage elements, which are not shown in Fig. 5. In particular, second end sections of the energy storage elements can be arranged in the second energy storage end zone 176.

[0275] The temperature control zone 152, arranged opposite the first temperature control zone 174 in Fig. 5, is a second temperature control zone 178. The second temperature control zone 178 extends through the second energy storage end zone 176.

[0276] A further temperature control zone 181 is shown in Fig. 5 between the first temperature control zone 174 and the second temperature control zone 178.

[0277] The separation element 160, already mentioned in connection with Fig. 4, is shown on the right-hand side in Fig. 5. An additional separation element 183 is also provided there, which is shown on the left-hand side in Fig. 5.

[0278] The separation elements 160 and 183 each serve to separate the temperature control zones 152, between which they each run, from one another.

[0279] The separation elements 160 and 183 each have spacers 184. The spacers 184 can serve as support elements 186. As shown in Fig. 5, they can extend, in particular, wholly or partially through the first temperature control zone 174 and / or through the second temperature control zone 178. Preferably, they can extend along the third direction 140.

[0280] The four outer shell elements 118 shown in Fig. 5 can form components of a housing 188 of the energy storage system 180, in particular of the energy storage unit 100 or an energy storage unit 100 which belongs to the energy storage system 180.

[0281] Figure 5 clearly shows that the temperature control fluid supply system 190 has a supply zone 192 for supplying a temperature control fluid. The temperature control fluid supply system has two supply zones 192, one of which is a first supply zone 194 and the other a second supply zone 196. The first supply zone 194 is fluid-conductingly connected to the first temperature control zone 174 via the supply passage 166, which was already described in connection with Figure 4.

[0282] The second supply zone 196 is fluid-conductingly connected to the second temperature control zone 178 via a passage 164 for the supply of temperature control fluid, i.e., via a supply passage 166. The passage 164, through which the fluid-conducting connection exists between the first supply zone 194 and the first temperature control zone 174, thus forms a first passage 198, in particular a first supply passage 200.

[0283] The passage 164, through which the fluid-conducting connection exists from the second supply zone 196 to the second temperature control zone 178, thus forms a second passage 202, in particular a second supply passage 204.

[0284] Fig. 6 shows a section through an inlet unit 110. The inlet unit 110 comprises an inlet nozzle. The inlet nozzle 206 is fluidly connected to a temperature control fluid distribution zone 208, in which a temperature control fluid introduced through the inlet nozzle 206 can be distributed. In the temperature control fluid distribution zone 208, the temperature control fluid can be distributed, in particular, to inlet zones 210, e.g., to a first inlet zone 212 and a second inlet zone 214. The temperature control fluid distribution zone 208 is fluidly connected to the first supply zone 194 via the first inlet zone 212. The temperature control fluid distribution zone 208 is fluidly connected to the second supply zone 196 (not shown in Fig. 6) via the second inlet zone 214.

[0285] Fig. 7 shows a section through an outlet unit 112. The outlet unit 112 has an outlet nozzle 216. The outlet nozzle 216 is fluidly connected to a discharge zone 220 via an outlet zone 218.

[0286] The energy storage system 180, in particular an energy storage unit 100 belonging to the energy storage system 180 and / or the temperature control fluid supply system 190, can advantageously have a discharge zone 220, already visible in Fig. 5, for discharging temperature control fluid from at least one of the temperature control zones. An end of the discharge zone 220 facing the outlet zone 218 is shown in Fig. 7. It can be particularly advantageous if, as can be seen in Figs. 5 and 7, the discharge zone is fluidly connected to the further temperature control zone 181, e.g., the core zone temperature control zone 222, via a passage 164 for discharging temperature control fluid from the further temperature control zone 181, which can be, for example, a core zone temperature control zone 222.

[0287] The passage 164 for draining temperature control fluid from the further temperature control zone 181, e.g., from the core zone temperature control zone 222, thus forms, in particular, a discharge passage 224 for draining temperature control fluid from the further temperature control zone 181, e.g., from the core zone temperature control zone 222. From the combined view of Figures 1 to 7, it is clear that the temperature control fluid guidance system 190 described therein is designed such that temperature control fluid can be guided through the first temperature control zone 174 in a first main flow direction 226 and temperature control fluid can be guided through the second temperature control zone 178 in a second main flow direction 228. The first main flow direction 226 and the second main flow direction 228 are in the same direction and parallel to each other.

[0288] Through the further temperature control zone 181, for example through the core zone temperature control zone 222, temperature control fluid can be guided in a further main flow direction 230. The further main flow direction 230 is opposite to the first main flow direction 226 and the second main flow direction 228. The further main flow direction 230 is parallel to, but opposite to, the first main flow direction 226 and the second main flow direction 228.

[0289] The core zone temperature control zone 222, located between the first temperature control zone 174 and the second temperature control zone 178, is fluidly connected to the two temperature control zones 174 and 178 via the passages 168 for the discharge of temperature control fluid from the first temperature control zone 174 and from the second temperature control zone 178.

[0290] There, temperature control fluid from the two temperature control zones 174 and 178 can pass through the separation elements 160 and 183 into the core temperature control zone 222 located between the two temperature control zones 174 and 178.

[0291] The energy storage zone 114 has a zone 232. Sections of the energy storage elements 116 extend into this zone. These sections of the energy storage elements 116 are not visible in Fig. 4, for example, because they are obscured there by the separation element 160. The sections of the energy storage elements can, for example, be different from the end sections of the energy storage elements 116.

[0292] The further temperature control zone 181 extends through zone 232 of the energy storage zone 114. Zone 232 of the energy storage zone 114 is a core energy storage zone 234, distinct from the first energy storage end zone 172 and the second energy storage end zone 176.

[0293] The section shown in Fig. 8 is similar to the section shown in Fig. 5. However, Fig. 8 shows further details; for example, it additionally shows the intermediate layer 126 and the propagation barrier 122. In this respect, the section view in Fig. 5 is simplified. Furthermore, Fig. 8 shows the energy storage elements 116. The third energy storage zone extension 138, measurable in the third direction 140, and the second energy storage zone extension 134, measurable in the second direction 136, are shown with dashed lines in Fig. 8. The third energy storage zone extension 138 can, in particular, be a thickness 139 of the energy storage zone. The second energy storage zone extension 134 can, in particular, be a width 146 of the energy storage zone.

[0294] In Fig. 8, certain energy storage elements 116 are shown hatched. These energy storage elements lie in the section plane. In addition, an energy storage element not lying in the section plane is shown as a dotted line in Fig. 8.

[0295] The ends 148 of energy storage elements 116 shown in Fig. 4 are oriented to the right in Fig. 8. These ends are the first ends 236 of the energy storage elements 116. In addition, the energy storage elements 116 each have a second end 238.

[0296] The first energy storage end zone 172 extends to the first ends 236 of the energy storage elements 116. The first temperature control zone 174 extends through the first energy storage end zone 172. The second energy storage end zone 176 extends to the second ends 238 of the energy storage elements 116. In the second energy storage end zone 176, second end sections of the energy storage elements 116 can be arranged. The second temperature control zone 178 extends through the second energy storage end zone 176.

[0297] Figure 9 shows another section through one of the energy storage units 100 belonging to the energy storage system 180, which has already been described with reference to Figures 1 to 8. Figure 9 illustrates how the various energy storage elements 116 are arranged in the energy storage zone. The dashed lines show how the second energy storage zone extension 134, in particular the width 146 of the energy storage zone, can be measured in the second direction 136. Similarly, the first energy storage zone extension 130, in particular the length 144 of the energy storage zone, can also be measured in the first direction 132, in particular in the main extension direction 142.

[0298] Figure 10 shows the inlet zones 192 and outlet zones 220 in the open state. Figure 10 also indicates the inlet flow directions 240, in which the temperature control fluid can flow in the inlet zones 192, and the outlet flow directions 242, in which the temperature control fluid can flow in the outlet zones.

[0299] Figures 14 to 22 show another energy storage system 180. There are many similarities between the energy storage system 180 shown in Figures 1 to 10 and the energy storage system 180 shown in Figures 14 to 22. The following description of Figures 14 to 22 will focus in particular on the differences between the two energy storage systems 180.

[0300] Like the energy storage system 180 shown in Figures 1 to 10, the energy storage system 180 shown in Figures 14 to 22 also has several energy storage zones. An additional energy storage zone 244 is shown, for example, in Figure 16. Further energy storage elements 246 are arranged in this additional energy storage zone. Unlike the energy storage system shown in Figures 1 to 10, both energy storage zones in the energy storage system shown in Figures 14 to 22 can be temperature-controlled by an integrated temperature control fluid system 190. For example, the temperature control fluid system 190 can be used to control the temperature of the energy storage elements 116 and the additional energy storage elements 246.

[0301] Figures 17 and 18 show two sections through the further energy storage system 180. In Figure 15, the Roman numerals XVII and XVIII indicate where the energy storage system 180 shown there was cut for the creation of the sectional views in Figures 17 and 18.

[0302] Figures 17 and 18 show that the temperature control fluid system 190, which serves to control the temperature of the energy storage elements 116 and the further energy storage elements 246, has two temperature control circuits. One of the temperature control circuits 248 controls the temperature of the energy storage elements 116, and another of the temperature control circuits 250 controls the temperature of the further energy storage elements 246. The energy storage elements 116 and 246 are not shown in Figures 17 and 18. However, the exploded view in Figure 16 readily shows where the energy storage elements 116 and 246 are arranged in the energy storage system 180.

[0303] One difference between the energy storage system 180 shown in Figs. 14 to 22 and the energy storage system 180 shown in Figs. 1 to 10 is that the supply zone 192, in particular the first supply zone 194, is a common supply zone 252, from which a temperature control fluid for use in the temperature control of the energy storage elements 116 and a further temperature control fluid for use in the temperature control of the further energy storage elements 246 can be provided proportionally, e.g. half each.

[0304] From the common feed zone 252, a temperature control fluid for the temperature control circuit 248 and another temperature control fluid for the further temperature control circuit 250 can be provided.

[0305] A comparison of Figures 17 and 18 clearly shows that the feed zone 192, in particular the common feed zone 252, narrows in the feed flow direction 240. The cross-sectional area of ​​the feed zone 192, in particular the common feed zone 252, is smaller in a downstream feed section 254 (shown in Figure 18) than in an upstream feed section 256 (shown in Figure 17).

[0306] The further feed zones 192 shown in Figs. 17 and 18 form a second feed zone 196 of the temperature control circuit 248 and a further feed zone 196 of the further temperature control circuit 250.

[0307] These two additional feed zones also taper in the same way as described for the common feed zone 252. In these additional feed zones as well, the flow cross-sections in a feed section 254 located downstream in the feed flow direction 240 are smaller than the flow cross-sections in upstream feed sections 256.

[0308] In addition to the discharge zone 220, which has already been described in connection with the energy storage system 180 of Figures 1 to 10, the energy storage system according to Figures 14 to 22 has a further discharge zone 258. The discharge zone 220 is fluid-conducted to the temperature control circuit 248. The further discharge zone 258 is fluid-conducted to the further temperature control circuit 250.

[0309] The two discharge zones 220 and 258 widen in the respective discharge flow direction 242. In the two discharge zones 220 and 258, a flow cross-section of the respective discharge zone 220 or 258 in a discharge section 260 located downstream in the discharge flow direction 242 is larger than a flow cross-section of the respective discharge zone 220 or 258 in a discharge section 262 located upstream in the discharge flow direction 242.

[0310] Fig. 19 shows a perspective view of a partially assembled energy storage system 180. The four separation elements 160, 183 shown comprise two inner separation elements 160 and two outer separation elements 183. The separation elements 160 and 183 are designed as separate components 264. These are separation units 266 designed as separate components 264. Fig. 20 shows a perspective view of a section through the common feed zone 252. A separation sealing zone 268 is indicated by dashed lines. One of the separation elements 160 shown in Fig. 19 can abut the separation sealing zone 268, for example, by being connected to it in a sealing manner, such as via an intermediate sealing element.

[0311] In Fig. 20, a further separation sealing zone 270 is indicated, to which a further separation unit 183 can be attached, for example in a sealing manner, in particular via an intermediate sealing element.

[0312] Fig. 21 shows another part of the same section in perspective. Since the further energy storage system 180, shown in Figs. 14 to 22, has a further discharge zone 258 in addition to the discharge zone 220, the further energy storage system 180 has a temperature control fluid merging zone 272 in which temperature control fluid obtained from the discharge zones 220 and 258 can be combined.

[0313] Figure 22 shows the inlet and outlet zones in the open state. The perspective view shown there makes it particularly clear that the inlet zones 192 taper in the inlet flow direction 240 and that the outlet zones widen in the outlet flow direction 242.

[0314] In the energy storage system 180 shown in Figs. 1 to 10, the energy storage elements in the two energy storage units 100 are each positioned and / or arranged by means of a positioning unit 274.

[0315] Figures 11 to 13 show such a positioning unit 274.

[0316] The positioning unit 274 has a separation element 160. The separation element 160 has recesses 276 for receiving energy storage elements 116.

[0317] The recesses 276 lie within a receiving surface 278. The receiving surface 278 is indicated in Fig. 11 by dashed lines. A receiving surface length 280 measurable in a first direction 132 is greater than a receiving surface width measurable in a second direction 136 orthogonal to the first direction 132. The positioning unit 274 has the following, in particular for guiding a temperature control fluid in the second direction 136 through a temperature control zone 152 delimited by means of the separation element 160: a passage 164 for supplying temperature control fluid into the temperature control zone. The passage 164 for supplying temperature control fluid to the temperature control zone 152 is formed on an edge 284 of the separation element 160 and / or the receiving surface 278, wherein the edge 284 limits the separation element 160 and / or the receiving surface 278 in the second direction 136.

[0318] A passage 168 for the discharge of temperature control fluid from the temperature control zone 152, wherein the passage 168 for the discharge of temperature control fluid from the temperature control zone 152 is formed at an edge 284 of the separation element 160 and / or the receiving surface 278, wherein the edge 284 limits the separation element 160 and / or the receiving surface 278 in the second direction 136.

[0319] The edge 284 of the separation element 160 and / or the receiving surface 278, on which the passage 164 for supplying temperature control fluid into the temperature control zone 152 is formed, is a supply-side edge 286 of the separation element 160 and / or the receiving surface 278.

[0320] The edge 284 of the separation element 160 and / or the receiving surface 278, on which the passage 168 for the discharge of temperature control fluid into the temperature control zone 152 is formed, is a discharge-side edge 288 of the separation element 160 and / or the receiving surface 278.

[0321] The positioning unit 274 also includes a temperature control fluid barrier 290, particularly for guiding a temperature control fluid in the second direction 136 through a temperature control zone 152, which can be delimited by means of the separation element 160. The temperature control fluid barrier 290 limits the longitudinal extent 292 of the temperature control zone 152, which can be delimited by means of the separation element 160, along the first direction 132. The temperature control fluid barrier 290 prevents the escape of temperature control fluid from the temperature control zone 152, which can be delimited by means of the separation element 160, along the first direction 132. The temperature control fluid barrier 290 prevents the escape of temperature control fluid from the temperature control zone 152, which can be limited by means of the separation element 160, along the first direction 132 and / or against the first direction 132.

[0322] The separation element 160 has spacers 184. The spacers 184 can be support elements 186.

[0323] As can be seen particularly clearly from Fig. 5, the spacers 184 can extend in or through one of the temperature control zones 152, 174 that can be delimited by means of the separation element 160. Fig. 5 shows that the spacers 184 of the separation element 160 extend through the temperature control zone 152 delimited by means of the separation element 160, in particular into or through the first temperature control zone 174 delimited by means of the separation element 160.

[0324] The spacers 184 extend in a third direction 140, which runs perpendicular to the first direction 132 and the second direction 136.

[0325] The positioning unit 274 has a wall section 293 and a supply zone separation element 294. The supply zone separation element 294 is formed by the wall section 293.

[0326] The wall section 293 and the supply zone separation element 294 extend transversely to the separation element 160, starting from the separation element 160.

[0327] The wall section 293 and the supply zone separation element 294 extend from the edge 284, in particular from the supply-side edge 286, of the separation element 160, which limits the separation element 160 in the second direction 136.

[0328] The wall section 293 and the supply zone separation element 294 extend in a third direction 140, which is orthogonal to the first direction 132 and the second direction 136, starting from the separation element 160.

[0329] Particularly from Figures 12 and 13 it can be clearly seen that the positioning unit

[0330] 274 has a feed zone 192 and a discharge zone 220. The feed zone 192 is the first feed zone 194 already described herein, particularly in connection with Fig. 5. The positioning unit 274 has a second feed zone 196, which is the second feed zone 196 already described, particularly in connection with Fig. 5.

[0331] The positioning unit 274 has the feed zones 192, 194, 196 and the discharge zone 220 on the wall section 293 and thus on the supply zone separation element 294. The positioning unit 274 has a supply zone separation element 296 between each of the feed zones 192, 194, 196 and the discharge zone 220.

[0332] The supply zone separation element 296, which includes the positioning unit 274 between the first feed zone 194 and the discharge zone 220, is a first supply zone separation element 298.

[0333] The supply zone separation element 296, which has the positioning unit 274 between the second feed zone 196 and the discharge zone 220, is a second supply zone separation element 300.

[0334] The positioning unit 274 has a frame element 302 spaced apart from the separation element 160. The frame element 302 is spaced apart from the separation element 160 in the third direction 140.

[0335] The positioning unit 274 is a plastic part 304. The plastic part 304 can be a plastic part manufactured by injection molding.

[0336] The positioning unit 274 shown in Figures 1 to 13 and described in more detail with reference to Figures 11 to 13 can include a separation unit 306 and thus be a multi-part positioning unit 274. The separation unit 306 is not shown in Figures 11 to 13. However, the separation unit 306 can be seen, for example, in Figure 5. The further separation element 183 shown there is formed by a separation unit 306.

[0337] Fig. 5 also shows that the further separation element 183 has further recesses 308 for receiving energy storage elements 116. The positioning unit 274 has a corresponding further recess 308 of the further separation element 183 for each recess 276 of the separation element 160, so that two recesses 276, 308 are available for receiving each energy storage element 116.

[0338] The frame element 302 has a support shoulder 310 on which the separation unit 306 can rest and / or be fixed, e.g. by gluing or welding.

[0339] As can be clearly seen in particular in Fig. 12, a further temperature control fluid barrier 312 can be formed on the frame element 302.

[0340] The further energy storage system 180 described with reference to Figures 14 to 22 has a fluid supply device 320. This is clearly visible, for example, in the exploded view of Figure 16. For the sake of clarity only, an outer casing element 118, integrally formed with the fluid supply device 320, is shown in Figure 16 above the energy storage zones 114 and 244 shown therein, spaced apart from the other components of the fluid supply device 320.

[0341] The fluid supply device 320 has a wall section 293 which also forms a supply zone separation element 294.

[0342] The fluid supply device 320 has an energy storage receiving zone 322. The energy storage zone 114 is formed within the energy storage receiving zone 322. The energy storage zone 114 is formed within the energy storage receiving zone 322 by means of the energy storage elements 116. The energy storage elements 116 are arranged on two positioning units 274 for this purpose.

[0343] The fluid supply device 320 has a further energy storage receiving zone 324. Within this further energy storage receiving zone 324, a further energy storage zone 244 is formed. This further energy storage zone 244 is formed within the further energy storage receiving zone 324 by means of further energy storage elements 246. The further energy storage elements 246 are arranged on two further positioning units 326. This is particularly evident from Figures 16 and 17, although in Figure 17 the energy storage elements 116 and 246 of the respective energy storage zones 114 and 244 are omitted.

[0344] The positioning units 274 and 326 also function as separation elements 160, 183, by separating different temperature zones from each other.

[0345] The positioning units 274 and 326 are separate components 264. This is particularly evident from Fig. 19. The separate components 264 are separation units 266.

[0346] The fluid supply device 320 has a supply zone 328 for supplying a temperature control fluid into the energy storage receiving zone 322 and / or discharging a temperature control fluid from the energy storage receiving zone 322.

[0347] Particularly as can be seen from Figures 26 and 27, a part 330 of the wall section 293, which forms part of the supply zone separation element 294, is arranged between the energy storage receiving zone 322 and the supply zone 328. Another part 332 of the wall section 293, which forms another part of the supply zone separation element 294, is arranged between the further energy storage receiving zone 324 and the supply zone 328.

[0348] There is a fluid-conducting connection between supply zone 328 and energy storage absorption zone 322. There is also a fluid-conducting connection between supply zone 328 and the further energy storage absorption zone 324.

[0349] The fluid supply device 320 has a receiving zone separating element 352 that spatially separates the two energy storage receiving zones 322, 324 (Figs. 18 and 19).

[0350] The wall section 293 and / or the supply zone separation element 294 are arranged between the two energy storage receiving zones 322 and 324 and the supply zone 328. A fluid-conducting connection exists between the supply zone 328 and the energy storage receiving zone 322. A fluid-conducting connection exists between the supply zone 328 and the further energy storage receiving zone 322. The fluid-conducting connections are configured such that a temperature control fluid can be supplied to the two energy storage receiving zones 322 and 324 from at least one supply zone 192, 194, 196 of the supply zone 328, and that a temperature control fluid can be discharged from both energy storage receiving zones 322, 324 into at least one discharge zone 220, 258 of the supply zone.

[0351] Supply zone 328 has the feed zones 192, 194 and 196 already described in connection with Figures 14 to 22. It also has the discharge zones 220 and 258 already described in connection with Figures 14 to 22.

[0352] Supply zone 328 has the supply zones 192, 194 and 196 and the discharge zones 220 and 258 on the wall section 293, which forms the supply zone separation element 294.

[0353] Between each supply zone and each discharge zone, a supply zone separation element 296 is arranged.

[0354] It is particularly evident from Fig. 26 that the length 334 of the supply zone, measurable in a first direction 132, is greater than the width 336 of the supply zone, measurable transversely to it, and in particular orthogonally in a third direction 140. Furthermore, it is also clearly evident from Fig. 26 that the length 338 of the energy storage absorption zone 322, measurable in the first direction 132, is greater than the width 340 of the energy storage absorption zone 322, measurable transversely to it, and in particular orthogonally in a second direction 136.

[0355] The fluid supply device 320 is a housing element 342 of a housing 188 for the further energy storage system 180, which has been described in particular with reference to Figures 14 to 22. The fluid supply device 320 delimits the energy storage receiving zone 322 on both sides in the first direction 132 and also on both sides in the second direction 136. In the embodiment of a fluid supply device 320 shown in Figures 14 to 28, a wall element 344 extends around the energy storage receiving zone 322 and another wall element 346 extends around the further energy storage receiving zone 324. Figure 23 is similar to Figure 8, but Figure 23 shows a section created through the further energy storage system 180, which is shown in Figures 14 to 22. Consequently, it can be seen that further energy storage elements 246 of the further energy storage zone 244 are also cut.A third energy storage zone extension 348, measurable in the third direction 140, of the further energy storage zone is a thickness 350 of the further energy storage zone.

[0356] Fig. 24 illustrates, as a representative example of one of the two energy storage zones 114 and 244 shown in Fig. 16, how their lengths 144 and widths 146 can be measured along the first direction 132 and the second direction 136.
