Detailed Implementation

[0056] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0057] In one aspect of this application, a housing for an energy storage system is provided. For example... Figures 1 to 3 As shown, Figure 1 This is a structural diagram of the energy storage system's enclosure and working unit, showing the assembly state; Figure 2 This is a structural diagram of the energy storage system's enclosure and working unit, showing the disassembled and removed state; Figure 3 This is a schematic diagram of the energy storage system's enclosure.

[0058] The enclosure 1 of the energy storage system includes a partition 3 and a housing unit 11. The housing unit 11 is used to house the working unit 2 of the energy storage system. The working unit 2 may include a battery pack, a liquid cooling unit, a converter, a switch, or an energy management device, etc.

[0059] The receiving unit 11 includes a sidewall portion 11a extending along a first direction. The working unit 2 is capable of entering or exiting the receiving unit 11 along the first direction to achieve assembly and disassembly with the receiving unit 11. The aforementioned spacer portion 3 is provided between the working unit 2 and at least one sidewall portion 11a.

[0060] The spacer 3 has a certain structural strength to reduce or prevent the working unit 2 from bulging outward. Here, "preventing" means that the spacer 3 can form a rigid constraint in the direction of the bulging of the working unit 2, thereby reducing or preventing the deformation of the working unit 2.

[0061] By adopting the energy storage system housing in this solution, the partition 3 is provided between the side wall 11a and the working unit 2, thereby reducing or blocking the deformation of the working unit 2 and preventing the faulty working unit 2 from squeezing the receiving unit 11.

[0062] Specifically, the housing 1 includes several receiving units 11 arranged in an array. Each receiving unit 11 is a housing structure with one end open. Both the working unit 2 and the spacer 3 can enter or exit the receiving unit 11 through the opening. The housing 1 also includes a cover for sealing the opening of the receiving unit 11.

[0063] Specifically, both the working unit 2 and the spacer 3 are movable along the extending direction of the sidewall portion 11a to enter or exit the receiving unit 11. Within the receiving unit 11, the sidewall portion 11a, the spacer 3, and the working unit 2 are configured to be distributed along a second direction. In this second direction, the working unit 2 is located on the side of the spacer 3 furthest from the sidewall portion 11a.

[0064] In this embodiment, the cross-sectional shape of the accommodating unit 11 can be a rectangle as shown in the figure, or it can be a circle, triangle, square, pentagon, or hexagon, etc. Those skilled in the art can choose according to their needs.

[0065] The partition 3 can be a plate-shaped structure formed by at least one sheet of plate, or a box-shaped structure welded from sheet metal. The partition 3 can also be a frame structure welded from profiles, the cross-section of which can be circular, square, I-shaped, or H-shaped, etc., and the profiles can also be made of steel or high-strength aluminum alloy, etc., to suppress or block the deformation of the working unit 2.

[0066] Furthermore, the spacer 3 can be made of metal or non-metal, as long as it can at least partially suppress the deformation of the working unit 2.

[0067] In this embodiment, the spacer 3 is connected to the receiving unit 11, and the spacer 3 is provided with a connecting portion 4. The connecting portion 4 is located outside the receiving unit 11 and abuts against the end wall on the corresponding side of the side wall portion 11a in a first direction. After the connecting portion 4 is connected to the end wall, the end wall, the connecting portion 4 provided on the end wall, and the opening of the receiving unit 11 can be covered by the cover portion. As a result, the installation of the spacer 3 and the receiving unit 11 can be facilitated.

[0068] The spacer 3 can be fixedly connected to the housing unit 11. Alternatively, the spacer 3 can be detachably connected to the housing unit 11, allowing it to be removed from within the housing unit 11. When it is necessary to disassemble and remove the faulty working unit 2, the spacer 3 can also be disassembled and removed together, thereby further reducing the difficulty of disassembling the faulty working unit 2 and improving the convenience of energy storage system maintenance.

[0069] In order to achieve a detachable connection between the spacer 3 and the receiving unit 11, the connecting part 4 and the end wall can adopt a detachable structure such as a threaded fastening connection or a snap-fit ​​connection, which ensures that the spacer 3 is accurately positioned in the receiving unit 11, while facilitating the removal of the spacer 3 from the receiving unit 11.

[0070] In a specific example, the connecting part 4 is a plate-like structure, which can be a straight plate or a bent plate. Part of the connecting part 4 is welded to the spacer 3, and part of it extends beyond the spacer 3 to the outside of the receiving unit 11. The connecting part 4 has a through hole for fasteners to pass through, and the end wall also has a through hole adapted to the through hole. The fastener passes through the connecting part 4 and the end wall in sequence and is fixed by a threaded pair.

[0071] Alternatively, the spacer 3 may be provided with at least two connecting portions 4, which may be symmetrically arranged with respect to the centerline of the spacer 3. The centerline of the spacer 3 extends along a first direction and passes through the midpoint of the spacer 3. Both connecting portions 4 abut against the end walls of their respective sides along the first direction.

[0072] By setting two connecting parts 4, it is possible to avoid the spacer 3 being subjected to force on one side, and at the same time, it is possible to ensure the positioning accuracy of the spacer 3 within the receiving unit 11.

[0073] The following section uses a rectangular cross-sectional shape for the housing unit 11 as an example to explain the arrangement of the working unit 2, the partition 3, and the side wall 11a, as well as the detachable connection between the partition 3 and the housing unit 11.

[0074] In one specific embodiment, please refer to Figures 1 to 5 as well as Figures 6 to 8 , Figure 4 yes Figure 2 A magnified schematic diagram of the local structure of region B in the middle; Figure 5 yes Figure 1 Enlarged schematic diagram of a local structure in region A; Figure 6 It is one of the connection structures between the partition and the sidewall when the working unit, the partition, and the sidewall adopt the first distribution method; Figure 7 When the working unit, the partition, and the sidewall adopt the first distribution method, the connection structure between the partition and the sidewall is the second one. Figure 8 This is the third connection structure between the partition and the sidewall when the working unit, the partition, and the sidewall adopt the first distribution method.

[0075] like Figure 6-8 As shown, the interval 3, the side wall 11a and the working unit 2 are distributed along the y-direction, that is, the second direction is the y-direction in the figure.

[0076] The sidewall portion 11a includes two first sidewall portions 11a-1 distributed opposite each other along the y-direction and two second sidewall portions 11a-2 distributed opposite each other along the x-direction. The size of the first sidewall portion 11a-1 is larger than the size of the second sidewall portion 11a-2. A spacer portion 3 is disposed between at least one first sidewall portion 11a-1 and the working unit 2, thereby reinforcing the larger sidewall portion 11a of the accommodating unit 11.

[0077] As an optional approach, please see Figure 2 , Figure 4 as well as Figure 6 The working unit 2 includes a shell portion 21 with an opening and a cover portion 22 fixedly connected to the shell portion 21. The shell portion 21 is a one-piece molded structure, and the cover portion 22 is detachably connected to the shell portion 21 by means of threaded connection or other means. The cover portion 22 includes a cover body 221, which covers the opening of the shell portion 21. After the working unit 2 and the receiving unit 11 are assembled, one of the two first sidewall portions 11a-1 is opposite to the cover body 221 in the y-direction. In order to reinforce the first sidewall portion 11a-1 facing the cover body 221, a spacer portion 3 is provided between the first sidewall portion 11a-1 and the cover body 221.

[0078] In this embodiment, in order to achieve a detachable connection between the spacer 3 and the receiving unit 11, please refer to... Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figures 6 to 8The following is an explanation of the diagram. The receiving unit 11 has a socket 14 for the working unit 2 and the partition 3 to enter and exit. The first side wall portion 11a-1 has a first end wall 11a-11, and the second side wall portion 11a-2 has a second end wall 11a-21. The first end wall 11a-11 and the second end wall 11a-21 are both located on the same side as the socket 14 and are on the same plane.

[0079] In one example, such as Figure 6 As shown, two connecting portions 4 can be respectively disposed on both sides of the spacer portion 3 along the x-direction. One connecting portion 4 abuts against the second end wall 11a-21 on one side along a first direction. The other connecting portion 4 abuts against the second end wall 11a-21 on the other side along a first direction. Wherein, the first direction is... Figures 1 to 5 In the z-direction, Figures 6 to 8 The direction perpendicular to the paper.

[0080] In another example, such as Figure 7 As shown, both connecting portions 4 extend along the y-direction toward the outside of the receiving unit 11 in a direction away from the working unit 2, and abut against the upper first end wall 11a-11 located in the paper direction along the first direction. Unlike the previous embodiment, in this embodiment, both connecting portions 4 abut against the upper first end wall 11a-11 located in the first direction.

[0081] In yet another example, such as Figure 8 As shown, the spacer 3 is provided with four connecting parts 4, which abut against the second end wall 11a-21 and the first end wall 11a-11 in the first direction respectively.

[0082] By using the connecting part 4 of this application to connect the spacer part 3 to the side wall part 11a, the spacer part 3 can be fixed in a predetermined position within the receiving unit 11. For example, the spacer part 3 may have a certain gap between itself and the working unit 2, or it may have a certain gap between itself and the side wall part 11a, thereby facilitating the assembly and disassembly of the spacer part 3.

[0083] In another specific embodiment, please refer to Figures 9 to 11 As shown, Figure 9 It is one of the connection structures between the interval section and the side wall section when the working unit, the interval section and the side wall section adopt the second distribution method; Figure 10 This is the second connection structure between the interval and the sidewall when the working unit, the interval, and the sidewall adopt the second distribution method. Figure 11 This is the third connection structure between the interval and the sidewall when the working unit, the interval, and the sidewall adopt the second distribution method.

[0084] Unlike the previous embodiments, in this embodiment, the spacer 3, the side wall portion 11a, and the working unit 2 are distributed along the x-direction, that is, the second direction is the x-direction in the figure. The spacer 3 is disposed between the second side wall portion 11a-2 and the working unit 2. In this embodiment, the cover body 221 may also be opposite to the spacer 3 along the x-direction, thereby the spacer 3 can reinforce the second side wall portion 11a-2 facing the cover body 221.

[0085] To achieve the connection between the spacer 3 and the sidewall 11a, in one example, such as Figure 9 As shown, two connecting portions 4 can be disposed on both sides of the spacer portion 3 along the y-direction and located outside the receiving unit 11. One connecting portion 4 abuts against the first end wall 11a-11 on one side along the first direction. The other connecting portion 4 abuts against the first end wall 11a-11 on the other side along the first direction.

[0086] In another example, such as Figure 10 As shown, both connecting parts 4 extend along the x-direction toward the outside of the receiving unit 11 in a direction away from the working unit 2, and abut against the second end wall 11a-21 on the left side in the first direction in the direction of the paper.

[0087] In yet another example, it could also be like this: Figure 11 As shown, four connecting parts 4 are provided, and the four connecting parts 4 respectively abut against the second end wall 11a-21 and the first end wall 11a-11 along the first direction.

[0088] This allows the spacer 3 to be fixed in a set position. For example, a certain gap is formed between the spacer 3 and the second side wall portion 11a-2, and a certain gap is also formed between the spacer 3 and the working unit 2.

[0089] In the aforementioned embodiments, the size of the first sidewall portion 11a-1 may be smaller than or equal to the size of the second sidewall portion 11a-2. Furthermore, a spacer portion 3 may be provided between both the first sidewall portion 11a-1 and the second sidewall portion 11a-2 and the working unit 2.

[0090] The following is combined Figures 12 to 29 Taking the frame structure of the partition 3 as an example, the structure of the partition 3 is illustrated. The frame structure of the partition 3 can suppress the deformation of the working unit 2 while achieving the dual optimization of structural lightweighting and manufacturing cost.

[0091] It includes a connecting beam assembly 32 and an outer frame 31 fixed to the connecting beam assembly 32. The outer frame 31 is a continuous and uninterrupted closed-loop structure. The use of the closed-loop outer frame 31 effectively prevents the deformation of the working unit 2.

[0092] The outer frame 31 is configured to align with the edge of the working unit 2 along the second direction, thereby enabling the spacer 3 to completely cover the working unit 2 and further stop the deformation of the working unit 2. Here, "alignment" includes both the case where the projection of the outer frame 31 and the edge of the working unit 2 in the second direction strictly coincides, and the case where, within the allowable range of processing errors, the projection of the outer frame 31 and the edge of the working unit 2 in the second direction partially coincides.

[0093] Specifically, the geometry of the outer frame 31 is consistent with the outer contour of the working unit 22.

[0094] like Figures 12-19 As shown, the outer frame 31 has an elliptical structure to fit the elliptical outline of the working unit 22. Alternatively, as... Figures 20-27 As shown, the outer frame 31 of the interval 3 is quadrilateral, which is adapted to the working unit 22 with a quadrilateral outline.

[0095] In this embodiment, the connecting beam assembly 32 is fixed to the inner side of the outer frame 31. The connecting beam assembly 32 includes a plurality of beam portions 320. Some of the beam portions 320 may intersect to form connecting beam assemblies 32 with different structures, or all of the beam portions 320 may intersect to form connecting beam assemblies 32 with different structures. The beam portions 320 and the beam portions 320 and the outer frame 31 may be fixed together by welding or other methods.

[0096] The spacer 3 can form a multi-directional load transfer path through the intersection design of at least some of the beams 320, thereby forming a local reinforced area (i.e., a "reinforced area") of the spacer 3. The flexural modulus of the reinforced area is significantly improved compared with that of the ordinary area, which can effectively reduce or avoid excessive deformation of the working unit 2 after implosion and avoid the compression between the working unit 2 and the receiving unit 11.

[0097] In some examples, the intersecting beams 320 converge at the same location. This optimizes the load transfer path and reduces stress concentration, thereby effectively reducing or avoiding excessive deformation of the working unit 2 after implosion.

[0098] Please see Figure 12 , Figure 13 , Figure 20 as well as Figure 21 middle, Figure 12 This is one of the structural schematic diagrams of the partition section; Figure 13 This is the second structural schematic diagram of the partition section; Figure 20 This is a structural schematic diagram of the partition section, part nine; Figure 21 This is a structural schematic diagram of the partition section, number ten. (See diagram below.) Figure 12 , Figure 13 , Figure 20 as well as Figure 21In the example shown, each beam portion 320 intersects with each other, and all the beam portions 320 intersect at the same position. Of course, it is also possible that some of the beam portions 320 intersect with each other, and the intersecting beam portions 320 all intersect at the same position.

[0099] As an alternative, as Figure 12 and Figure 20 shown, the connecting beam assembly 32 includes two beam portions 320, and the two beam portions 320 intersect at the same position and are perpendicular to each other. Of course, the two beam portions 320 can also be arranged at an acute or obtuse angle.

[0100] More specifically, as Figure 12 shown, the outer frame 31 is an oval beam, and the two beam portions 320 intersect at the same position. One beam portion 320 is arranged along the long axis direction of the outer frame 31, and the other beam portion 320 is arranged along the short axis direction of the outer frame 31. It can also be as Figure 20 shown, the outer frame 31 is a rectangular beam, one beam portion 320 extends in the same direction as the long side of the outer frame 31 and passes through the center of the short side of the outer frame 31, and the other beam portion 320 extends in the same direction as the short side of the outer frame 31 and passes through the center of the long side of the outer frame 31.

[0101] As another alternative, as Figure 13 and Figure 21 shown, the spacer portion 3 is provided with four beam portions 320, and the four beam portions 320 intersect at the same position at a set angle to form a structure similar to a "rice" character. More specifically, as Figure 13 shown, the outer frame 31 is an oval beam, and each beam portion 320 intersects at the center of the oval beam. It can also be as Figure 21 shown, the outer frame 31 is a rectangular beam. In addition to the two beam portions 320 arranged along the symmetry axis of the outer frame 31, the spacer portion 3 further includes two beam portions 320 arranged along the diagonal of the outer frame 31, and each beam portion 320 intersects at the center of the outer frame 31.

[0102] Of course, in addition to the above embodiments, the number of the beam portions 320 can also be three or an integer greater than four, and those skilled in the art can choose by themselves. In addition, each beam portion 320 intersects at the same position within the strengthening area, and this intersection position can be located at the center of the outer frame 31 or can be spaced from the center of the outer frame 31.

[0103] In some other examples, as Figure 14 and Figure 22 shown, Figure 14 is the schematic structural view of the spacer portion, No. three; Figure 22 is the schematic structural view of the spacer portion, No. eleven.

[0104] The connecting beam assembly 32 forms a network structure. The network structure is formed by multiple beams 320 that are orthogonal or oblique to each other. The network structure of the connecting beam assembly 32 can form a multi-directional load transfer path, thereby reducing the bending moment and stress concentration borne by a single beam, significantly improving the structural strength of the spacer 3, and effectively suppressing the deformation of the spacer 3.

[0105] In some other examples, such as Figures 15 to 19 as well as Figures 23 to 27 As shown, Figure 15 This is a structural schematic diagram of the partition section, part four; Figure 16 This is a structural schematic diagram of the partition section, part five; Figure 17 This is a schematic diagram of the partition structure, part six; Figure 18 This is a structural schematic diagram of the partition section, part seven; Figure 19 This is a structural schematic diagram of the partition section, part eight; Figure 23 This is a schematic diagram of the spacer section, number 12; Figure 24 This is a structural schematic diagram of the partition section, part thirteen; Figure 25 This is a schematic diagram of the structure of the partition section, number fourteen. Figure 26 This is a schematic diagram of the structure of the partition section, number fifteen; Figure 27 This is a schematic diagram of the spacer section, number sixteen.

[0106] The beam section 320 includes a first type of beam section 321 and a second type of beam section 322. The first type of beam section 321 is a continuous ring beam without any breaks, and the second type of beam section 322 is fixedly connected between the first type of beam section 321 and the outer frame 31.

[0107] By adopting a combined structure of the first type of beam 321, the second type of beam 322, and the outer frame 31, the first type of beam 321, the second type of beam 322, and the outer frame 31 of the closed-loop structure work together to distribute the load and improve the stability of the spacer 3 structure.

[0108] In a specific example, such as Figure 15 and Figure 23 As shown, the first type of beam 321 is a circular or elliptical beam, and the first type of beam 321 is provided with at least two second type of beams 322. At least two second type of beams 322 extend in the same direction. This balances the forces on the first type of beam 321 in the same direction, increasing the rigidity of the first type of beam 321.

[0109] In such Figure 15 and Figure 23 In the example shown, the first type of beam 321 is a circular beam, and at least two second type of beams 322 are symmetrically arranged at 180° along the circumference of the first type of beam 321. The extensions of the at least two second type of beams 322 pass through the center of the first type of beam 321 and form an angle of 180°.

[0110] By adopting this method, the bidirectional forces along the radial direction of the first type of beam 321 can be effectively balanced, making the load distribution more even and preventing deformation of the first type of beam 321.

[0111] In another specific example, the first type of beam 321 is a quadrilateral beam. In such... Figure 16 In the example shown, when the first type of beam 321 is a rectangular beam and the outer frame 31 is an elliptical beam, the long side of the first type of beam 321 extends in the same direction as the minor axis of the outer frame 31, and the short side of the first type of beam 321 extends in the same direction as the major axis of the outer frame 31. Figure 24 In the example shown, when the first type of beam 321 is a rectangular beam and the outer frame 31 is also a rectangular beam, the long side of the first type of beam 321 is parallel to the short side of the outer frame 31, and the short side of the first type of beam 321 is parallel to the long side of the outer frame 31. This improves the geometric fit between the first type of beam 321 and the outer frame 31.

[0112] In yet another specific example, such as Figures 17 to 19 as well as Figures 25 to 27 As shown, the first type of beam 321 can also be a pentagonal beam. Of course, in addition to the above-mentioned methods, the first type of beam 321 can also be a triangular beam or a hexagonal beam, etc., which can be selected by those skilled in the art as needed.

[0113] In the foregoing embodiments, please refer to Figure 18 , Figure 19 , Figure 26 as well as Figure 27 When the first type of beam 321 is a polygonal beam, its corner position intersects with at least one second type of beam 322, thereby improving the stiffness of the corner position of the polygonal beam. The corner position of the polygonal beam can have one second type of beam 322, or two or more second type of beams 322. When two or more second type of beams 322 are provided at the same corner position, one end of each second type of beam 322 intersects at the same corner position, while the other ends are spaced apart and fixed to the outer frame 31. This further facilitates the transfer of load at the corner position of the polygonal beam, further increasing the stiffness of the reinforced area.

[0114] In another example, the spacer 3 may also be provided with a third type of beam 323. For example... Figure 19 and Figure 27As shown, one end of the third type beam 323 is fixed to the second type beam 322, and the fixed position of the third type beam 323 to the second type beam 322 is located between the two ends of the second type beam 322. The other end of the third type beam 323 is directly or indirectly fixed to the outer frame 31. The third type beam 323 can be directly welded to the outer frame 31, or it can be indirectly fixed to the outer frame 31 through another beam 320.

[0115] In the aforementioned embodiments, such as Figures 15 to 19 as well as Figures 23 to 27 As shown, the second type of beam 322 extends radially outward from the first type of beam 321. The beams of the second type of beam 322 near the first type of beam 321 are densely arranged, while the beams near the outer frame 31 are dispersed.

[0116] This achieves localized reinforcement of the spacer 3, while the way the second type of beam 322 is distributed on the side near the outer frame 31 can disperse the load, thus taking into account both the requirements of lightweight and high rigidity.

[0117] In other embodiments, when the spacer 3 is provided with a plurality of beams 320, at least some of the beams 320 are fixed to the outer frame 31, and at least some of the beams 320 are separated from each other. That is, some of the beams 320 are not intersecting each other, and some of the beams 320 intersect each other; or, all of the beams 320 are separated from each other.

[0118] For example, it can be like Figure 28 As shown, Figure 28 This is a structural schematic diagram of the partition section, number seventeen; the beams are distributed in parallel at 320° intervals. It could also be as follows: Figure 29 As shown, Figure 29 This is a structural schematic diagram of the partition section, number eighteen. The beams 320 are distributed at a certain angle, but they are all separated from each other and have no intersection.

[0119] In the aforementioned embodiments, the outline edge of the spacer 3 is configured to be aligned with the edge of the working unit 2 along the second direction, thereby enabling the spacer 3 to completely cover the working unit 2 and further suppress the deformation of the working unit 2.

[0120] Here, "alignment" includes both the case where the projection of the edge of the spacer 3 and the edge of the working unit 2 in the second direction strictly coincides, and the case where, within the allowable range of processing error, the projection of the edge of the spacer 3 and the edge of the working unit 2 in the second direction partially coincides.

[0121] Specifically, when the spacer 3 is provided with an outer frame 31, the geometry of the outer frame 31 is consistent with the outer contour of the working unit 22.

[0122] like Figures 12-19 As shown, the outer frame 31 is an elliptical beam, designed to fit the elliptical working unit 22. Alternatively, as... Figures 20-29 As shown, the outer frame 31 of the partition 3 is a quadrilateral beam, which is adapted to fit the working unit 22 with a quadrilateral outline.

[0123] In the aforementioned embodiments, Figures 12 to 29 The diagram shows the planar structure of the partition 3. In space, within the dimension range of the outer frame 31 along the second direction, each beam 320 can be distributed coplanarly or staggered along the second direction. That is, the center lines of each beam 320 can be located on the same plane to form a two-dimensional planar frame system; or, the center lines of each beam 320 can be staggered along the second direction to form a three-dimensional spatial frame system.

[0124] In another aspect of this application, please refer to Figures 1 to 5 As shown, this application also provides an energy storage system, which includes a working unit 2 and the aforementioned housing 1. The working unit 2 can enter or exit the housing unit 11 along a first direction, and the partition 3 is located between the side wall portion 11a of the working unit 2 and the housing unit 11 along a second direction to suppress or block the deformation of the working unit 2. This improves the ease of maintenance of the energy storage system.

[0125] In the aforementioned embodiments, the sidewall portion 11a belonging to the same receiving unit 11 can be a one-piece structure or a separate connected structure. As one configuration of the receiving unit 11, in... Figures 1 to 5 In the example shown, the box 1 is composed of horizontal and vertical plates arranged at preset intervals. The horizontal and vertical plates are joined vertically to form a regular grid-like frame, which is divided into multiple independent and evenly distributed housing units 11. The horizontal and vertical plates can be fixedly connected using mortise and tenon joints or welding.

[0126] During the operation of the energy storage system, when an implosion occurs in a working unit 2, the working unit 2 bulges outward. The spacer 3 can suppress this bulging in the direction of expansion, thereby reducing the deformation of the working unit 2.

[0127] When the spacer 3 is detachably connected to the housing unit 11, after the working unit 2 undergoes an implosion, the spacer 3 and the working unit 2 can be extracted together from the housing unit 11.
