Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to an integrated energy storage cabinet. Background Technology

[0002] With the widespread application of batteries in the energy storage field, large-capacity integrated energy storage cabinets have become the mainstream research and application target for major energy storage manufacturers and users.

[0003] Existing integrated energy storage cabinets consist of a frame and battery clusters, with each cluster comprising a rack and multiple batteries. The rack is installed within and welded to the frame, and its internal structure is divided into multiple installation spaces, with batteries inserted one by one into their corresponding spaces. Due to the limited space in each single layer, battery insertion is difficult, time-consuming, and labor-intensive. Furthermore, after insertion, gaps exist between the batteries and the rack in the width direction of the frame, and between adjacent battery layers in the height direction. This results in low space utilization and low integration of the integrated energy storage cabinet. Utility Model Content

[0004] Therefore, it is necessary to provide an integrated energy storage cabinet that can simplify operation, improve space utilization and integration to address the above problems.

[0005] An integrated energy storage cabinet includes a frame and a battery cluster. The battery cluster is disposed within the frame and includes a support base and multiple batteries. All the batteries are stacked on the support base.

[0006] In two adjacent battery layers, the upper battery and the lower battery are connected by a concave-convex fit. In adjacent batteries and the support base, the upper battery and the lower support base are connected by a concave-convex fit.

[0007] In some embodiments, the battery includes an outer casing;

[0008] In two adjacent battery layers, the battery in the upper layer further includes one of a plurality of plug-in tubes and plug-in posts arranged circumferentially around its outer casing, and the battery in the lower layer further includes another of a plurality of plug-in tubes and plug-in posts arranged circumferentially around its outer casing, with the plug-in tubes and plug-in posts being plugged in one-to-one.

[0009] In the adjacent batteries and the support base, the upper battery also includes one of a plurality of plug tubes and plug posts arranged circumferentially around its outer casing, and the lower support base has another of the plug tubes and plug posts arranged circumferentially, with the plug tubes and plug posts corresponding to each other in a concave-convex fit.

[0010] In some embodiments, in the same battery having the plug and the plug tube, the plug and the plug tube correspond one-to-one, and the corresponding plug and the plug tube are stacked in the stacking direction of the battery.

[0011] In some embodiments, in the same battery having the plug and the plug tube, all the plug and all the plug tubes correspond one-to-one with all the corners of the outer casing, and the plug and the plug tubes are all disposed at the corresponding corners.

[0012] In some embodiments, the top of the outer casing is an open end, and the outer casing includes a bottom plate disposed opposite to the open end. In two adjacent battery layers, the bottom plate of the upper battery covers the open end of the lower battery, and the bottom plate and the open end it covers are in a concave-convex fit.

[0013] In some embodiments, in two adjacent battery layers, the corresponding plug post and plug tube are plugged into and abut against each other along the stacking direction of the batteries, and the base plate and the open end covered therewith are spaced apart in the stacking direction of the batteries.

[0014] In some embodiments, the top battery further includes a cover plate that covers the open end of the top battery.

[0015] In some embodiments, the frame has two first supports arranged along its width direction, the battery has an outer casing and two fastener groups, the two fastener groups protruding from the outer casing and facing the two first supports respectively, and the two fastener groups correspond one-to-one with the two first supports and are detachably connected.

[0016] In some embodiments, the first support has a bottom beam, the top surface of which forms a sliding surface;

[0017] The support base has two second brackets, each corresponding to one of the first brackets. The bottom of each second bracket has a sliding block. The sliding block is slidably disposed on the sliding surface of the corresponding bottom beam and slides along the sliding surface under the action of an external force to allow the battery cluster to enter and exit the frame.

[0018] In some embodiments, the bottom of the support base has an insertion space for a transport device to pass through, so as to move the battery cluster between the inside and outside of the frame by the transport device.

[0019] Compared with the prior art, this application has the following beneficial effects:

[0020] In the aforementioned integrated energy storage cabinet, the upper battery layer and the lower battery layer have a concave-convex mating connection. This allows the upper battery to fit snugly against the lower battery under its own weight, and so on, until all batteries are assembled into a single unit. Similarly, in adjacent batteries and support bases, the upper battery layer and the lower support base have a concave-convex mating connection, allowing the upper battery to fit snugly against the lower support base under its own weight, and so on, until all batteries and support bases are assembled into a battery cluster. This design results in a tight and secure fit between adjacent batteries and between batteries and support bases, reducing or eliminating gaps in the height direction of the frame, thus achieving high space utilization and integration. After assembly, the battery cluster is pushed into the frame's receiving space, completing the installation in one go. The operation is simple, convenient, and saves time and effort. In addition, the cluster rack is omitted in this application, simplifying the structure. Furthermore, there is no gap between the battery and the cluster rack in the width direction of the frame. Considering that the battery cluster can be pushed in at once and is easy to operate even in a small space, the dimensions in the width direction of the frame can be appropriately reduced, thereby reducing the gap between the cabinet and the battery in the width direction of the frame, so as to improve the space utilization and integration of the integrated energy storage cabinet.

[0046] With the widespread application of batteries in the energy storage field, large-capacity integrated energy storage cabinets have become the mainstream research and application target for major energy storage manufacturers and users.

[0047] Existing integrated energy storage cabinets consist of a frame and battery clusters, with each cluster comprising a rack and multiple batteries. The rack is installed within and welded to the frame, and its internal structure is divided into multiple installation spaces, with batteries inserted one by one into their corresponding spaces. Due to the limited space in each single layer, battery insertion is difficult, time-consuming, and labor-intensive. Furthermore, after insertion, gaps exist between the batteries and the rack in the width direction of the frame, and between adjacent battery layers in the height direction. This results in low space utilization and low integration of the integrated energy storage cabinet.

[0048] Please see Figures 1 to 9 To alleviate the aforementioned problems, the applicant, after in-depth research, designed an integrated energy storage cabinet. The integrated energy storage cabinet includes a cabinet body 10 and battery clusters 20. The cabinet body 10 includes a frame 11, and the battery clusters 20 are disposed within the frame 11. Each battery cluster 20 includes a support base 21 and multiple batteries 22, all of which are stacked on the support base 21. In adjacent layers of batteries 22, the upper battery 22 and the lower battery 22 are connected in a concave-convex fit. Similarly, in adjacent batteries 22 and support bases 21, the upper battery 22 and the lower support base 21 are connected in a concave-convex fit.

[0049] The cabinet 10 also includes a base 13 and a cover 12. The frame 11 mainly serves the functions of installation and storage. The frame 11 is installed on the base 13, and the frame 11 has an internal structure that forms a receiving space 113 and an entrance / exit communicating with the receiving space 113. The cover 12 covers the frame 11 and the base 13 and is used to cover the surface of the frame 11 that does not have an entrance / exit or face the base 13, as well as the side circumference of the base 13, in order to improve the aesthetics of the cabinet 10.

[0050] Specifically, the bottom surface of the frame 11 faces the base 13 and is in contact with the base 13. The inlet and outlet of the frame 11 are located on one side of the frame 11 along the length direction X. The side surface of the frame 11 opposite to the inlet and outlet along its length direction X, the two surfaces of the frame 11 opposite to each other along its width direction Y, the top surface of the frame 11, and the side peripheral surface of the base 13 are all covered with skin 12.

[0051] The internal accommodating space 113 of the frame 11 is divided into multiple sub-accommodating spaces 1131 arranged along the height direction Z of the frame 11. Different sub-accommodating spaces 1131 are used to place different components. For example, there are three sub-accommodating spaces 1131: one sub-accommodating space 1131 is used to place the liquid cooling unit 50, another sub-accommodating space 1131 is used to place the high-voltage box 30 and the converter 40, and the remaining sub-accommodating space 1131 is used to place the battery pack 20. Of course, the number of sub-accommodating spaces 1131 and the types of components placed in each sub-accommodating space 1131 are not limited to the above one, and can also be in other forms, which are not limited here.

[0052] Batteries 22 are stacked on support base 21, and the stacking direction of batteries 22 is consistent with the height direction Z of frame 11. Support base 21 can be a desktop structure, frame 11 structure, etc., which can be set according to requirements.

[0053] In two adjacent battery layers 22, the upper battery 22 and the lower battery 22 are interlocked, allowing the upper battery 22 to fit tightly against the lower battery 22 under its own weight. This process continues until all batteries 22 are connected to form a single unit. Similarly, in adjacent batteries 22 and support bases 21, the upper battery 22 and the lower support base 21 are interlocked, allowing the upper battery 22 to fit tightly against the lower support base 21 under its own weight. This process continues until all batteries 22 and support bases 21 are connected to form a battery cluster 20. This design ensures a tight and secure fit between adjacent batteries 22 and between batteries 22 and support bases 21, reducing or eliminating gaps in the height Z direction of the frame 11, resulting in high space utilization and integration. After assembly, the battery cluster 20 is pushed into the receiving space 113 of the frame 11, completing the installation in one step. This operation is simple, convenient, and saves time and effort. Furthermore, the cluster rack is omitted in this application, simplifying the structure. In addition, there is no gap between the battery 22 and the cluster rack in the width direction Y of the frame 11. Considering that the battery cluster 20 can be pushed in at once and is easy to operate even in a small space, the dimensions in the width direction Y of the frame 11 can be appropriately reduced, thereby reducing the gap between the cabinet 10 and the battery 22 in the width direction Y of the frame 11, so as to improve the space utilization and integration of the energy storage cabinet.

[0054] Please see Figure 1 , Figures 5 to 10 In some embodiments, the battery 22 includes an outer casing 221 and a battery module 225 disposed within the outer casing 221. In two adjacent battery layers 22, the upper battery 22 further includes one of a plurality of circumferentially spaced plug-in tubes 223 and plug-in posts 222 surrounding its outer casing 221, and the lower battery 22 further includes the other of a plurality of circumferentially spaced plug-in tubes 223 and plug-in posts 222 surrounding its outer casing 221. The plug-in tubes 223 and plug-in posts 222 are inserted into each other in a one-to-one correspondence. In adjacent battery 22 and support base 21, the upper battery 22 further includes one of a plurality of circumferentially spaced plug-in tubes 223 and plug-in posts 222 surrounding its outer casing 221, and the lower support base 21 has the other of a circumferentially spaced plug-in tube 223 and plug-in post 222, with the plug-in tubes 223 and plug-in posts 222 correspondingly engaged in a one-to-one correspondence.

[0055] As an example, in two adjacent battery layers 22 and in adjacent battery 22 and support base 21, the upper battery 22 includes a plug-in tube 223 arranged circumferentially around its outer casing 221, the lower battery 22 includes a plug-in post 222 arranged circumferentially around its outer casing 221, and the lower support base 21 has plug-in posts 222 spaced circumferentially therebetween. The plug-in posts 222 are inserted upward into the corresponding plug-in tube 223 to achieve a concave-convex mating between adjacent battery layers 22 and between adjacent battery 22 and support base 21. In this embodiment, the top battery 22 includes a plug-in tube 223, the support base 21 includes a plug-in post 222, and the remaining batteries 22 located between the top battery 22 and the support base 21 all include plug-in posts 222 and plug-in tubes 223. The top battery 22 refers to the battery 22 furthest from the support base 21 along its stacking direction.

[0056] Of course, in some other embodiments, in adjacent battery layers 22 and in adjacent battery layers 22 and support bases 21, the upper battery 22 may include a plug-in post 222 circumferentially arranged around its outer casing 221, the lower battery 22 may include a plug-in tube 223 circumferentially arranged around its outer casing 221, and the lower support base 21 may have plug-in tubes 223 spaced circumferentially therearound. The plug-in post 222 is inserted downward into the corresponding plug-in tube 223 to achieve a concave-convex mating between adjacent battery layers 22 and between adjacent battery layers 22 and support base 21. In this embodiment, the top battery 22 includes a plug-in post 222, the support base 21 includes a plug-in tube 223, and the remaining batteries 22 located between the top battery 22 and the support base 21 also include plug-in posts 222 and plug-in tubes 223.

[0057] By providing one of a connector tube 223 and a connector post 222 in the upper battery 22, and the other of a connector tube 223 and a connector post 222 in the lower battery 22 or support base 21, with the connector post 222 being inserted into the connector tube 223, the lower support base 21 or battery 22 can stably support the upper battery 22. The resulting battery cluster 20 has a stable overall structure and is not easily collapsed.

[0058] In some embodiments, in the same battery 22 having a plug post 222 and a plug tube 223, the plug post 222 and the plug tube 223 correspond one-to-one, and the corresponding plug post 222 and plug tube 223 are stacked in the stacking direction of the battery 22.

[0059] It can be understood that the battery 22 with plug-in post 222 and plug-in tube 223 is the battery 22 located between the top battery 22 and the support base 21. The battery 22 located between the top battery 22 and the support base 21 is defined as the battery 22 of the middle layer. In the battery 22 of the middle layer, the plug-in post 222 and the plug-in tube 223 correspond one-to-one, and the corresponding plug-in post 222 and plug-in tube 223 are stacked in the stacking direction of the battery 22.

[0060] Specifically, the plug tube 223 is a hollow structure with one end open and the other end closed. The closed end of the plug tube 223 faces the corresponding plug post 222 in the same battery 22 and is used to install the corresponding plug post 222 in the same battery 22. The open end of the plug tube 223 faces the plug post 222 of the battery 22 in the layer adjacent to the battery 22 it is located in, and is used for the plug post 222 of the battery 22 in the layer adjacent to the battery 22 it is located in.

[0061] In two adjacent battery layers 22 (it is possible that both the upper and lower battery layers 22 are intermediate layer batteries 22, or the upper battery layer 22 is the top layer battery 22 and the lower battery layer 22 is the intermediate layer battery 22), the upper battery layer 22 has a plug tube 223 and the lower battery layer 22 has a plug post 222. Taking the plug tube 223 of the upper battery layer 22 and the plug post 222 of the lower battery layer 22 as an example, the open end of the plug tube 223 of the upper battery layer 22 faces downward and is plugged into the plug post 222 of the lower battery layer 22, and the closed end of the plug tube 223 of the upper battery layer 22 faces upward and is connected to the corresponding plug post 222 in the same battery layer 22.

[0062] The corresponding plug-in post 222 and plug-in tube 223 in the same battery 22 are arranged in a straight line along the height direction Z of the frame 11, and the space occupied by them in the width direction Y or length direction X of the frame 11 at least partially overlaps. The total space occupied by the corresponding plug-in post 222 and plug-in tube 223 in the same battery 22 is reduced, and the space utilization rate is high.

[0063] In some embodiments, in the same battery 22 having plug-in posts 222 and plug-in tubes 223, all plug-in posts 222 and all plug-in tubes 223 correspond one-to-one with all corners of the outer casing 221, and the plug-in posts 222 and plug-in tubes 223 are all located at the corresponding corners. Taking the outer casing 221 as a rectangle with four corners as an example, in the same battery 22 having plug-in posts 222 and plug-in tubes 223, there are four plug-in posts 222 and four plug-in tubes 223. Each corner is provided with one plug-in post 222 and one plug-in tube 223, and the plug-in posts 222 and plug-in tubes 223 at the same corner are stacked along the height direction Z of the frame 11.

[0064] By placing the plug-in pins 222 and plug-in tubes 223 at the corners of the outer casing 221, not only can the number of plug-in pins 222 and plug-in tubes 223 be reduced, but it can also ensure that the lower battery 22 can stably support the upper battery 22, and the batteries 22 are stacked stably. In addition, the support base 21 can also stably support all the batteries 22.

[0065] Please see Figure 1 , Figures 8 to 15 In some embodiments, the top of the outer casing 221 is an open end 2211. The outer casing 221 includes a bottom plate 2212 disposed opposite to the open end 2211. In two adjacent battery layers 22, the bottom plate 2212 of the upper battery 22 covers the open end 2211 of the lower battery 22. That is, the upper and lower battery layers 22 share a single bottom plate 2212. This method reduces the height occupied by the bottom plate 2212 of the battery 22 and improves the space utilization of the battery 22 in the height direction Z of the frame 11. In addition, the bottom plate 2212 and the open end 2211 it covers have a concave-convex fit to achieve a concave-convex fit between adjacent battery layers 22.

[0066] As an example, in two adjacent battery layers 22, the bottom plate 2212 of the upper battery 22 has a groove 2213, and the open end 2211 of the lower battery 22 has a protrusion 2214 arranged circumferentially along its opening, with the protrusion 2214 engaging with the groove 2213. Alternatively, in other embodiments, the bottom plate 2212 of the upper battery 22 may have a protrusion 2214 arranged circumferentially thereafter, and the open end 2211 of the lower battery 22 may have a groove 2213 arranged circumferentially along its opening, with the protrusion 2214 engaging with the groove 2213.

[0067] In this embodiment, in two adjacent battery layers 22, the bottom plate 2212 and the open end 2211 covering it are in a concave-convex fit, which is combined with one of the plug post 222 and plug tube 223 of the upper battery 22 and the other of the plug post 222 and plug tube 223 of the lower battery 22, so that the two adjacent battery layers 22 fit more tightly and the stacked batteries 22 are less likely to collapse.

[0068] In some embodiments, in two adjacent battery layers 22, the corresponding plug-in post 222 and plug-in cylinder 223 abut against each other in the stacking direction of the battery 22, and the base plate 2212 and the open end 2211 covering it are spaced apart in the stacking direction of the battery 22. In this case, the weight of all the batteries 22 is borne by the plug-in cylinder 223 and the plug-in post 222, and is finally transferred to the support base 21, avoiding deformation of the outer casing 221 and the internal battery module 225 due to the weight being borne by the outer casing 221, thus improving the safety of the battery 22 in use.

[0069] In some embodiments, the top battery 22 further includes a cover plate 224 that covers the open end 2211 of the top battery 22. After multiple batteries 22 are stacked, the open end 2211 of the top battery 22 is sealed by the cover plate 224 to prevent external moisture and other substances from entering the top battery 22, which helps to reduce the risk of insulation failure of the battery module 225 inside the top battery 22.

[0070] Please see Figures 1 to 5 In some embodiments, the frame 11 has two first supports 111 arranged along its width direction Y, and the battery 22 has an outer casing 221 and two fastener groups 226. The two fastener groups 226 protrude from the outer casing 221 and face the two first supports 111 respectively, and the two fastener groups 226 correspond one-to-one with the two first supports 111 and are detachably connected.

[0071] As an example, the first support 111 includes a plurality of first vertical beams 1111 spaced apart along the length X direction of the frame 11, and a top beam 1112 and a bottom beam 1113 spaced apart along the height Z direction of the frame 11. In the same first support 111, the top beam 1112 and the bottom beam 1113 are connected to all the first vertical beams 1111. The first support 111 also includes a plurality of first connecting beams 112, which correspond one-to-one with the first vertical beams 1111 in the first support 111. The two first vertical beams 1111 in two first supports 111 that correspond to the first connecting beams 112 are respectively connected to the two opposite ends of the first connecting beams 112.

[0072] The fastener assembly 226 includes two fasteners 2231. These two fasteners 2231 are spaced apart along the length X of the frame 11 on opposite sides of the corresponding first bracket 111, and are detachably connected to the first vertical beam 1111 of the corresponding first bracket 111 via screws, pins, etc. By providing the fastener assembly 226, the stability and reliability of the installation between the battery cluster 20 and the frame 11 are improved.

[0073] Please see Figures 2 to 3 ,as well as Figures 5 to 7 In some embodiments, the first bracket 111 has a bottom beam 1113, the top surface of which forms a sliding surface 11131; the support base 21 has two second brackets 211, which correspond one-to-one with the first bracket 111, and the bottom of the second bracket 211 has a sliding block 2114; the sliding block 2114 is slidably disposed on the sliding surface 11131 of the corresponding bottom beam 1113, and slides along the sliding surface 11131 under the action of external force so that the battery cluster 20 can enter and exit the frame 11.

[0074] As an example, the second support 211 includes a plurality of second vertical beams 2111 spaced apart along the length X of the frame 11, a horizontal beam 2112 extending along the length X of the frame 11, and a plurality of sliding blocks 2114. In the same second support 211, the horizontal beam 2112 is connected to all the second vertical beams 2111, and the sliding block 2114 corresponds one-to-one with the second vertical beam 2111, and the sliding block 2114 is disposed at the bottom of the corresponding second vertical beam 2111. The second support 211 also includes a plurality of second connecting beams 2113, the second connecting beams 2113 corresponding one-to-one with the second vertical beams 2111 in the second support 211, and the two second vertical beams 2111 corresponding to the second connecting beams 2113 in the two second supports 211 are respectively connected to the opposite ends of the second connecting beams 2113.

[0075] In this embodiment, the second vertical beam 2111 protrudes from the top of the second connecting beam 2113 and the horizontal beam 2112 to form a plug-in post 222 or a plug-in tube 223.

[0076] During actual installation, at least one sliding block 2114 of the first bracket 111 rests on the corresponding sliding surface 11131, and then an external force pushes the entire battery cluster 20 to slide, so that the battery cluster 20 enters the frame 11, facilitating the installation of the battery cluster 20. After installation, the fastener group 226 of the battery cluster 20 is connected to the corresponding first bracket 111.

[0077] The second bracket 211 also includes connecting blocks 2115. The second vertical beam 2111 in the same second bracket 211 is provided with connecting blocks 2115 on both sides that are opposite to each other along the length direction X or width direction Y of the frame 11. After the battery cluster 20 is installed in the frame 11, the connecting blocks 2115 on each side of the second vertical beam 2111 are detachably connected to the second vertical beam 2111, the sliding block 2114 located at the bottom of the second vertical beam 2111, and the bottom beam 1113 that carries the sliding block 2114 by detachable parts such as screws and pins.

[0078] Please see Figure 1 and Figure 4 ,as well as Figure 7 and Figure 8 In some embodiments, the bottom of the support 21 has an insertion space 2116 for a transport device to pass through, so as to move the battery cluster 20 between the inside and outside of the frame 11. The transport device (e.g., a forklift) is inserted into the insertion space 2116 and lifted to deliver the battery cluster 20 into the receiving space 113 of the frame 11, or to move it out of the frame 11, thus realizing the loading and unloading of the battery cluster 20. The insertion space 2116 facilitates the transfer of the battery cluster 20 by the transport device.

[0079] In the aforementioned integrated energy storage cabinet, in two adjacent battery layers 22, the upper battery 22 and the lower battery 22 have a concave-convex fit. This allows the upper battery 22 to fit tightly with the lower battery 22 under its own weight, and so on, until all batteries 22 are fitted together to form a single unit. Similarly, in adjacent batteries 22 and support bases 21, the upper battery 22 and the lower support base 21 have a concave-convex fit, allowing the upper battery 22 to fit tightly with the lower support base 21 under its own weight, and so on, until all batteries 22 and support bases 21 are fitted together to form a battery cluster 20. This design results in a tight and reliable fit between adjacent batteries 22 and between batteries 22 and support bases 21, reducing or eliminating gaps in the height direction Z of the frame 11, thus achieving high space utilization and integration. After the battery cluster 20 is assembled, it is pushed into the receiving space 113 of the frame 11, and the installation of the battery cluster 20 can be completed in one go. The operation is simple, convenient and saves time and effort. In addition, the cluster frame is omitted in this application, which simplifies the structure. In addition, there is no gap between the battery 22 and the cluster frame in the width direction Y of the frame 11. Considering that the battery cluster 20 can be pushed in at once, it is convenient to operate even in a small space. Therefore, the dimension in the width direction Y of the frame 11 can be appropriately reduced, so that the gap between the cabinet 10 and the battery 22 in the width direction Y of the frame 11 is reduced, thereby improving the space utilization and integration of the energy storage cabinet.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
