[0033] In the description of this application, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above and obliquely above the second feature, with the first feature having a higher horizontal height than the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, with the first feature having a lower horizontal height than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings. They are intended to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and do not have any special meanings.

[0036] With the increasing demand for the electrical capacity of energy storage containers, the number of battery packs included in the energy storage containers has also increased, and the number of auxiliary components has also increased, resulting in an increase in the total volume of the energy storage system. In some application scenarios, there are often restrictions on the overall size of the energy storage container. For example, in the process of transporting energy storage containers, larger energy storage containers cannot meet the loading requirements well. In the related art, in order to adapt to the layout of some components that constitute the energy storage container and avoid installation interference between components, the energy storage container needs to provide space for the installation of these components. However, the installation space provided in the related art is often excessive, thereby increasing the volume of the energy storage container and causing the energy storage container to occupy a larger space.

[0037] Based on the fact that energy storage containers in related technologies occupy a large space, an embodiment of the present application proposes an energy storage container.

[0038] Please refer to Figures 1 to 3. Figure 1 is an overall structural diagram of the energy storage container provided in an embodiment of the present application, Figure 2 is an internal structural diagram of the energy storage container provided in an embodiment of the present application, and Figure 3 is a structural diagram of the frame of the energy storage container provided in an embodiment of the present application.

[0039] The energy storage container 1 proposed in this application is used to house battery packs (not shown). It includes a frame 10 and multiple battery racks 20. Frame 10 serves as the main structural unit of the energy storage container 1, connecting the other components that make up the container 1. Frame 10 includes multiple corner posts and multiple crossbeams, with each corner post extending in the direction of gravity, and each crossbeam connecting two corner posts. Multiple battery racks 20 are installed within frame 10, with spacing between them to create a space between adjacent battery racks 20 for mounting battery packs.

[0040] Please refer to Figures 4 and 5. Figure 4 is a schematic structural diagram of one end of an energy storage container according to an embodiment of the present application, and Figure 5 is a cross-sectional view of a first corner post according to an embodiment of the present application. The multiple corner posts may include at least one first corner post 111. Each first corner post 111 is positioned adjacent to a battery rack 20. First corner post 111 includes an inner side facing toward battery rack 20, with a portion of the inner side concave inwardly facing away from battery rack 20 to form an accommodating space 1110. Accommodating space 1110 can accommodate at least a portion of battery rack 20.

[0041] Specifically, the first corner column 111 may include a first inner wall 1111 facing the battery rack 20, and a first outer wall 1112 opposite to the first inner wall 1111 and away from the battery rack 20. When viewed from the first inner wall 1111 to the first outer wall 1112, at least a portion of the projection of the battery rack 20 is located within the range of the first inner wall 1111. The portion of the first inner wall 1111 adjacent to the battery rack 20 is recessed toward the first outer wall 1112 to form an accommodating space 1110 that can accommodate at least a portion of the battery rack 20. In some embodiments, the first inner wall 1111 may include It includes a first section 11111, a second section 11112 and a first connecting section 11113, wherein the second section 11112 is located between the first section 11111 and the first outer wall 1112, and the first connecting section 11113 is connected between the first section 11111 and the second section 11112. When viewed from the first inner wall 1111 to the first outer wall 1112, the second section 11112 is the portion that overlaps with part of the battery rack 20, thereby forming an accommodating space 1110 between the first section 11111, the second section 11112 and the first connecting section 11113.

[0042] Please refer to Figure 6, which illustrates the assembly relationship between the first corner post and the battery rack according to an embodiment of the present application. In some embodiments of the present application, after the battery rack 20 is assembled within the frame 10, due to the presence of the accommodation space 1110, at least a portion of the battery rack 20, such as the support rails 24 of the battery rack 20, can be located within the accommodation space 1110, thereby minimizing interference with the first corner post 111. This allows the battery rack 20 to be assembled without expanding the size of the frame 10, thereby minimizing the size of the energy storage container, improving the internal space utilization rate of the energy storage container, and enhancing the structural compactness of the energy storage container 1.

[0043] In the embodiment of the present application, a portion of the inner side of the first corner post 111 is recessed inward in a direction away from the battery rack 20 to form an accommodation space 1110, so that the first corner post 111 can accommodate at least a portion of the battery rack 20 installed on the frame 10 through the accommodation space 1110. Advantageously, the frame 10 can accommodate the battery pack and electrical equipment without having to increase the overall size of the frame 10 to avoid interference between the battery rack 20 and the frame 10, thereby improving the structural compactness of the energy storage container 1.

[0044] 1 and 4 , the energy storage container 1 may further include a door 32 rotatably connected to the frame 10 . The plurality of corner posts may further include at least one second corner post 112 , each second corner post 112 being disposed adjacent to the door 32 . In some embodiments of the present application, the interior of the energy storage container 1 can be separated into a first compartment and a second compartment by a partition (not shown in the figure), wherein at least part of the space in the first compartment can be used to install multiple battery packs, and at least part of the space in the second compartment can be used to install the above-mentioned electrical equipment, which can be an energy storage converter and an energy management system (EMS), etc. These electrical equipment are used to control and manage the battery packs. Accordingly, the energy storage container can be provided with a first compartment opening and a second compartment opening, the first compartment opening is provided in the first compartment for connecting the first compartment with the outside space, and the second compartment opening is provided in the second compartment for connecting the second compartment with the outside space. The compartment door 32 may include a first compartment door and a second compartment door, the first compartment door is provided at the first compartment opening, the first compartment door is used to open and close the first compartment opening, and the second compartment door is provided at the second compartment opening, the second compartment door is used to open and close the second compartment opening. Two second corner posts 112 can be provided, one second corner post 112 is used to connect the first compartment door, and the other second corner post 112 is used to connect the second compartment door. This specification uses the second corner post 112 connected to the first door as an example to schematically describe the structure of the second corner post 112 provided in this embodiment. For details on the structure of the second corner post 112 connected to the second door, please refer to the relevant description. Specifically, please refer to Figures 7 and 8. Figure 7 is a cross-sectional view of the second corner post provided in this embodiment, and Figure 8 is a diagram illustrating the assembly relationship between the second corner post and the first door provided in this embodiment. Along the thickness direction of the warehouse door 32, each second corner column 112 may include a second inner wall 1121 and a second outer wall 1122 arranged opposite to each other, and the second inner wall 1121 and the second outer wall 1122 are respectively arranged on both sides of the warehouse door 32, wherein the second outer wall 1122 may include a third section 11221, a fourth section 11222 and a second connecting section 11223. Along the thickness direction of the warehouse door 32, the third section 11221 and the second inner wall 1121 are arranged on both sides of the warehouse door 32, the fourth section 11222 is located between the third section 11221 and the second inner wall 1121 and on the side of the third section 11221 facing the warehouse door 32, the second connecting section 11223 is bent and connected between the third section 11221 and the fourth section 11222, and an assembly space 1120 is formed between the third section 11221, the fourth section 11222 and the second connecting section 11223. Typically, the door 32 can be rotatably connected to the frame 10 using some rotating connectors 34. The rotating connectors 34 can be common hinges or other types of hinges. For example, a hinge can be installed on the surface of the second corner post 112 adjacent to the door 32. The hinge is connected between the second corner post 112 and the door 32, thereby allowing the door 32 to be rotatably set on the frame 10.In the embodiment of the present application, the third section 11221 and the fourth section 11222 can be distributed along the thickness direction of the warehouse door 32, wherein the third section 11221 is located on the side of the warehouse door 32 away from the battery rack 20, and the fourth section 11222 is located on the side of the third section 11221 facing the warehouse door 32, and the second connecting section 11223 is bent and connected between the third section 11221 and the fourth section 11222 and is arranged parallel to the thickness direction of the warehouse door 32, thereby forming an assembly space 1120 facing the warehouse door 32 on the second outer wall 1122, and the hinge is arranged in the assembly space 1120 and connects the fourth section 11222 and / or the second connecting section 11223. Such a design can provide an assembly space 1120 for the installation of the hinge or some other rotating connectors 34, so that after the rotating connector 34 is installed on the second corner column 112, the overall occupied space of the energy storage container 1 is not increased, thereby further improving the structural compactness of the energy storage container 1.

[0045] In some embodiments, the second inner wall 1121 of the second corner column 112 may include a fifth section 11211, a sixth section 11212 and a third connecting section 11213. Along the thickness direction of the warehouse door 32, the fifth section 11211 and the sixth section 11212 are arranged at intervals, the sixth section 11212 is located between the fifth section 11211 and the second outer wall 1122, the third connecting section 11213 is bent and connected between the fifth section 11211 and the sixth section 11212, and a first receiving space 1140 is formed between the fifth section 11211, the sixth section 11212 and the third connecting section 11213. The energy storage container 1 may further include a pipe 18, which may be a liquid cooling pipe for conveying coolant to the battery pack. At least a portion of the pipe 18 may be arranged on the second corner column 112 along the direction of gravity. In this case, the first receiving space 1140 may serve to accommodate a portion of the pipe 18. This design allows the pipe 18 to be arranged inside the frame 10 without interfering with the battery pack or some components, so that the pipe 18 can be arranged without increasing the size of the frame 10, which is conducive to further improving the structural compactness of the energy storage container 1.

[0046] In some embodiments, the assembly space 1120 for accommodating hinges and the first receiving space 1140 for accommodating pipes can be located in separate corner posts. Specifically, the multiple corner posts can further include at least one third corner post (not shown). Each third corner post is positioned adjacent to a pipe 18. The third corner post includes a third inner wall adjacent to the pipe 18, with a portion of the third inner wall recessed away from the pipe 18 to form a second receiving space. When some pipes 18, such as liquid cooling pipes for supplying coolant to the battery pack, are secured to the third corner post, the second receiving space can accommodate a portion of the pipes. This design also prevents the pipes from interfering with the battery pack or other components after being routed within the frame 10. This allows for the routing of the pipes without increasing the size of the frame 10, further improving the structural compactness of the energy storage container 1.

[0047] Please refer to Figures 1 and 9. Figure 9 is a schematic diagram of the other end of an energy storage container according to an embodiment of the present application. The energy storage container 1 may further include side panels 31 arranged parallel to the direction of gravity. These side panels 31 are connected to the frame 10 and, in conjunction with the frame 10, enclose a space for accommodating battery packs and / or electrical equipment. The multiple corner posts may further include at least one fourth corner post 113, each of which is positioned adjacent to a side panel 31.

[0048] Referring to Figures 10 and 11, Figure 10 is a cross-sectional view of a fourth corner post according to an embodiment of the present application, and Figure 11 is a diagram illustrating the assembly relationship between the fourth corner post and the side panel according to an embodiment of the present application. Along the thickness direction of the side panel 31, the fourth corner post 113 may include a fourth inner wall 1131 and a fourth outer wall 1132, which are arranged opposite each other. The fourth outer wall 1132 may include a seventh section 11321, an eighth section 11322, and a fourth connecting section 11323. Along the thickness direction of the side panel 31, the seventh section 11321 and the fourth inner wall 1131 are disposed on either side of the side panel 31. The eighth section 11322 is located between the seventh section 11321 and the fourth inner wall 1131, and on the side of the seventh section 11321 facing the side panel 31. The fourth connecting section is bent and connected between the seventh section 11321 and the eighth section 11322, forming an escape space 1130 between the seventh section 11321, the eighth section 11322, and the fourth connecting section 11323.

[0049] Typically, the four edges of the side panel 31 serve as mounting edges for connecting to the frame 10. In order to facilitate the installation of the side panel 31 on the frame 10, in some embodiments, the eighth section 11322 can be set to be closer to the side panel 31 than the seventh section 11321 in the direction from the fourth outer wall 1132 to the fourth inner wall 1131 (i.e., the thickness direction of the side panel 31), or the eighth section 11322 can be set to be flush with the side panel 31, thereby making the avoidance space 1130 closer to the side panel 31 or making the avoidance space 1130 flush with the surface of the side panel 31. When the side panel 31 is assembled, the side panel 31 is assembled. When 31 is assembled on the frame 10, or when the side panel 31 needs to be disassembled due to maintenance needs, some installation tools (such as wrenches and screwdrivers are more common) are needed to install and disassemble the side panel 31. Due to the existence of the avoidance space 1130, during this operation, the installation tool or the hand operating the installation tool, or part of the installation tool and part of the hand can be located within the avoidance space 1130, thereby reducing or even avoiding the interference between the installation tool or the hand and the fourth corner column 113, so that maintenance personnel can be more comfortable when installing and disassembling the side panel 31, thereby improving the convenience of installation and disassembly and improving the installation and disassembly efficiency.

[0050] Referring to FIG3 , in some embodiments of the present application, the frame 10 may have a rectangular parallelepiped shape. When the frame 10 has a rectangular parallelepiped shape, the frame 10 may include a bottom side 110, a top side 120, a first side 130, and a second side 140. The bottom side 110 and the top side 120 are disposed opposite each other in the direction of gravity, the first side 130 and the second side 140 are disposed opposite each other, and the first side 130 connects one side of the bottom side 110 and one side of the top side 120, while the second side 140 connects the other side of the bottom side 110 and the other side of the top side 120.

[0051] 9 , the crossbeam of the frame 10 may include a first crossbeam 121 , which is disposed at the junction of the bottom side 110 and the first side 130 . Referring to FIG12 , FIG12 is a cross-sectional view of the first crossbeam according to an embodiment of the present application. Along the direction of gravity, the first beam 121 may include a bottom wall 1211 and a top wall 1212 arranged opposite to each other, wherein the top wall 1212 may include a ninth section 12121, a tenth section 12122 and a fifth connecting section 12123. Along the direction of gravity, the ninth section 12121 and the tenth section 12122 are arranged at intervals, and the ninth section 12121 is arranged close to the first side 130 and the bottom side 110, and the tenth section 12122 is arranged close to the second side 140 and the top side 120. The fifth connecting section 12123 is bent and connected between the ninth section 12121 and the tenth section 12122. The ninth section 12121, the tenth section 12122 and the fifth connecting section 12123 form a receiving groove 1210. At least part of the warehouse door 32 is arranged on the first side 130 (i.e., the first warehouse door) and is rotatably connected to the frame 10, and the receiving groove 1210 can accommodate at least part of the warehouse door 32 close to the first beam 121. Specifically, taking the warehouse door 32 for opening and closing the first warehouse opening, i.e., the first warehouse door, as an example, the warehouse door 32 for opening and closing the second warehouse opening (i.e., the second warehouse door) can refer to the relevant description. In some embodiments, the warehouse door 32 may include a main body 321 and a locking rod 322 for locking the main body 321 to the first warehouse opening. The locking rod 322 is rotatably connected to the side of the main body 321 away from the hinge. The ninth section 12121 and the tenth section 12122 are arranged toward the top side 120, and the fifth connecting section 12123 is bent and connected between the ninth section 12121 and the tenth section 12122, thereby forming a receiving groove between the ninth section 12121, the tenth section 12122 and the fifth connecting section 12123. 1210, please refer to Figure 13, Figure 13 is an assembly relationship diagram between the first crossbeam and the first warehouse door provided in an embodiment of the present application. When the first warehouse door is in the state of closing the first warehouse opening, the end of the locking rod 322 facing the bottom side 110 will be able to be placed in the receiving groove 1210 and abut against the surface of the fifth connecting section 12123 facing the receiving groove 1210, and the bottom end of the main body 321 facing the bottom side 110 can be opposite to or abut against the tenth section 12122. Therefore, the receiving groove 1210 can accommodate at least part of the first warehouse door, so that the first warehouse door can avoid the locking rod 322 from occupying additional space when in the closed state, which can further improve the structural compactness of the energy storage container 1.

[0052] Please refer to Figures 9 and 14. Figure 14 is a front projection view of the first end of the frame provided in an embodiment of the present application. In addition to the above-mentioned first crossbeam 121, the crossbeam of the frame 10 may also include a second crossbeam 122. The second crossbeam 122 is provided at the connection between the bottom side 110 and the second side 140. In some embodiments of the present application, along the direction of gravity, the first crossbeam 121 has a first height, and the second crossbeam 122 has a second height, and the second height is greater than the first height. Since the frame 10 is subjected to a large force in the direction of gravity, the present application sets the second height of the second crossbeam 122 to be greater than the first height of the first crossbeam 121. The advantage is that the rigidity and strength of the second crossbeam 122 can be increased, thereby facilitating an increase in the load-bearing capacity of the frame 10.

[0053] 3 and 4 , the crossbeams may further include a third crossbeam 123 and a fourth crossbeam 124. The third crossbeam 123 is disposed at the junction of the first side 130 and the top side 120, and the fourth crossbeam 124 is disposed at the junction of the second side 140 and the top side 120. The frame 10 may further include a plurality of pillars 13. A plurality of pillars 13 may be spaced apart between the first crossbeam 121 and the third crossbeam 123, and between the second crossbeam 122 and the fourth crossbeam 124. The inventors of this application have discovered through extensive practice in implementing the technical solution of this application that, if the width of each pillar 13 is set to be no less than 100 mm in a direction parallel to the first crossbeam 121, the size of the energy storage container 1 can be minimized while ensuring good structural strength, thereby further improving the structural compactness of the energy storage container 1.

[0054] Continuing to refer to Figures 3 and 4, multiple battery racks 20 are spaced apart, with one end of each battery rack 20 being connected to the bottom side 110 and the other end being connected to the top side 120. Along the direction of gravity, each battery rack 20 may include a first crossbar 21 and a second crossbar 22 spaced apart. The first crossbar 21 is disposed on the bottom side 110 and connected between the first crossbar 121 and the second crossbar 122, and the second crossbar 22 is disposed on the top side 120 and connected between the third crossbar 123 and the fourth crossbar 124. The battery rack 20 may also include a plurality of vertical rods 23, with at least two vertical rods 23 connected between the first crossbar 21 and the second crossbar 22, and the at least two vertical rods 23 being spaced apart along the length of the first crossbar 21. Preferably, the width of each vertical rod 23 is not less than 50 mm in a direction parallel to the first crossbar 121. This ensures that the battery rack 20 has good strength while reducing its lateral width, which helps further improve the structural compactness of the energy storage container 1.

[0055] Referring to Figure 2 , each battery rack 20 may further include multiple load-bearing rails 24 . These rails are spaced apart between the first and second crossbars 21 and 22 and are connectable to at least two vertical bars 23 . Between each pair of adjacent battery racks 20 , multiple load-bearing rails 24 are spaced apart along the gravity direction, facing one battery rack 20 toward the other. The multiple load-bearing rails 24 of one battery rack 20 are positioned at the same height and opposite to the multiple load-bearing rails 24 of the other battery rack 20 . A load-bearing space for mounting battery packs is formed between the two equal and opposite load-bearing rails 24 between the two battery racks 20 . This load-bearing space gradually narrows from the first side 130 toward the second side 140 . Referring to Figure 15 , FIG15 is an exploded schematic diagram of the load-bearing rails provided in an embodiment of the present application. To facilitate placing the battery pack on the two supporting guide rails 24 oppositely arranged between the two battery racks, each supporting guide rail 24 may include a supporting portion 241 and a guiding portion 242. The supporting portion 241 is simultaneously connected to at least two vertical poles 23, and the guiding portion 242 is fixed to the supporting portion 241. The guiding portion 242 has an end close to the first side 130 and an end close to the second side 140. The thickness of the guiding portion 242 gradually increases from the first side 130 to the second side 140, so that the space between the two equal-height and oppositely arranged supporting guide rails 24 can gradually become narrower in the direction from the first side 130 to the second side 140. As a result, in the process of assembling the battery pack on the supporting guide rail 24, the two equal-height and oppositely arranged guiding portions 242 can better guide the battery pack during the process of pushing the battery pack in, thereby preventing the battery pack from deviating from the desired pushing direction when being pushed in.

[0056] Please continue to refer to Figure 16, which is a schematic structural diagram of the load-bearing portion 241 provided in an embodiment of the present application. In some embodiments, the load-bearing portion 241 may include a load-bearing member 2411 and a connecting member 2412, wherein the load-bearing member 2411 is used to carry the battery pack, and the connecting member 2412 is used to securely connect the load-bearing member 2411 to the vertical pole 23. Specifically, the load-bearing member 2411 may include a load-bearing edge 24111 and a limiting edge 24112, wherein the load-bearing edge 24111 and the limiting edge 24112 intersect, for example, the load-bearing edge 24111 and the limiting edge 24112 may be connected vertically or perpendicularly, wherein the load-bearing edge 24111 is used to carry the battery pack, and the limiting edge 24112 is connected to the vertical pole 23, and the limiting edge 24112 is used to limit the direction of movement of the battery pack, thereby reducing the situation where the battery pack is offset in direction when it is pushed into the carrying space. The connecting member 2412 can be a 45-degree bending member. The connecting member 2412 can include a first connecting edge 24121 and a second connecting edge 24122. The first connecting edge 24121 can be connected to the vertical pole 23, and the second connecting edge 24122 can be connected to the load-bearing edge 24111 to support the load-bearing edge 24111. A reinforcing structure 24123 can also be provided between the first connecting edge and the second connecting edge of the connecting member 2412 to improve the structural strength of the connecting member 2412. For example, a bulge or a rib can be designed between the first connecting edge 24121 and the second connecting edge 24122. Taking the bulge as an example, the bulge can be provided at one end of the first connecting edge 24121 close to the second connecting edge 24122 to abut the second connecting edge 24122.

[0057] In some embodiments, the guide portion 242 may include a guide member 2421 and a plurality of pads 2422. The guide member 2421 may include a guide edge 24211. After the guide member 2421 is assembled to the bearing portion 241, the guide edge 24211 of the guide member 2421 will be attached to the limiting edge 24112 of the bearing member 2411. The pads 2422 may be spaced apart in a direction from the first side to the second side (i.e., along the length direction of the limiting edge 24112) and sandwiched between the guide edge 24211 and the limiting edge 24112. , or a part of the pad 2422 is clamped between the guide edge 24211 and the limiting edge 24112, and the other part of the pad 2422 is arranged on the side surface of the guide edge 24211 away from the limiting edge 24112. From the first side to the second side, the thickness of the guide edge 24211 and / or the pad 2422 can be set to increase successively. Specifically, the thickness of the guide edge can be set to increase successively from the first side to the second side, multiple pads can be stacked and used, or several pads with different thicknesses can be designed. Exemplarily, when a pad is affixed to one end of the limiting edge 24112 close to the first side 130, the pads may not be stacked, or a pad of smaller thickness may be directly used. When a pad is affixed to the other end of the limiting edge 24112 close to the second side 140, two or more pads may be stacked, or a pad of larger thickness may be used. In this way, the bearing space between the two equal and opposite bearing guide rails 24 can gradually narrow from the first side to the second side, thereby effectively guiding the process of pushing the battery pack. Of course, the implementation method of using a guide edge with a thickness that increases successively along the length direction can also have an effective guiding effect on the process of pushing the battery pack. Or, under the premise of using a guide edge with a thickness that increases successively along the length direction, using pads of different thicknesses or stacking pads can also have an effective guiding effect on the process of pushing the battery pack. Those skilled in the art can choose one of the above-mentioned optional methods or use any combination thereof as appropriate.

[0058] In some embodiments of the present application, the pad 2422 sandwiched between the guide edge 24211 and the limiting edge 24112 can be made of sheet metal, polycarbonate (PC) or any other suitable material, and the pad 2422 arranged on the side of the guide edge 24211 away from the limiting edge 24112 is in direct contact with the surface of the battery pack. Therefore, the pad used in this case can be made of a relatively soft material such as rubber, silicone, etc., so as to cushion the impact on the battery pack when pushing the battery pack.

[0059] Referring to FIG. 1 , the energy storage container 1 may further include a top panel 33 disposed on the top side 120 of the frame 10, with at least a portion of the top panel 33 arched away from the top side 120. For example, in some embodiments, the middle portion of the top panel 33 may arch away from the top side 120 of the frame 10 by a predetermined height. For example, a 10 mm gap may be provided between the middle portion of the top panel 33 and the top side 120 of the frame 10. This design advantageously allows for convenient drainage of water and snow from the top of the energy storage container 1 when used outdoors. Alternatively, in other embodiments, the distance between one side of the top plate 33 and the top side 120 of the frame 10 can be designed to be greater than the distance between the other side of the top plate 33 and the top side 120 of the frame 10 on two opposite sides of the top plate 33. That is, the top plate 33 and the top side 120 of the frame 10 are arranged at an angle, and the top plate 33 is inclined relative to the top side 120 of the frame 10. In this way, when the energy storage container 1 is used in an outdoor environment, it can also effectively prevent water and snow from accumulating on the top of the energy storage container 1.

[0060] Continuing with FIG1 , in some embodiments, the energy storage container 1 may further include multiple explosion vent panels 331. One or more of the side panels 31, the door 32, and the top panel 33 may be provided with multiple explosion vents. Each explosion vent panel 331 covers one explosion vent, and the strength of the explosion vent panel 331 is configured to be less than the strength of the side panels 31, the door 32, and the top panel 33. For example, the top panel 33 of the energy storage container 1 may have five explosion vents, each covered by an explosion vent panel 331. In the event of an unexpected situation, such as a battery pack explosion caused by thermal runaway, the explosion energy may cause the explosion vent panels 331, which are weak areas, to be ruptured first. The interior of the energy storage container 1 may be connected to the outside world through the explosion vents, allowing some combustible gases to be released preferentially from the explosion vents, thereby minimizing damage to the energy storage container 1.

[0061] In related technologies, damage and premature scrapping of energy storage containers are common due to insufficient structural strength and carrying capacity. For example, in a 20-foot standard high-cube energy storage container, 5MWh and 6MWh energy storage containers weigh approximately 43 tons and over 50 tons, respectively. These containers significantly exceed the maximum load of approximately 40 tons for a 20-foot standard high-cube energy storage container, creating potential risks of uncertainty in the logistics and transportation of energy storage containers.

[0062] Please refer to Figures 3 and 4. Based on the fact that energy storage containers in related technologies have insufficient strength and limited carrying capacity, in some embodiments, the energy storage container 1 may further include a support beam 40, which is installed on the bottom side 110 and connects one end of each battery rack 20.

[0063] Please refer to Figures 3, 4, and 17. Figure 17 is a schematic diagram of the structure of the support beam 40 provided in an embodiment of the present application. The support beam 40 provided in an embodiment of the present application may include a web 43, which is installed on the bottom side 110. The web 43 may include a first side away from the top side 120, and the first side is connected to multiple battery racks 20. The first side may include two web ends 431 located at both ends and a web middle portion 432 located between the two web ends 431. The web middle portion 432 may be bent toward the top side 120 so that the distance between the web middle portion 432 and the top side 120 in the direction of gravity is less than the distance between any web end 431 and the top side 120.

[0064] Specifically, in some embodiments of the present application, a pre-arch process or any other suitable process (such as shearing, forging, and stamping) can be used to form the middle portion 432 of the web into an arc edge along the length direction of the support beam 40. The arc edge can be a curved shape that is convex toward the top side 120. The advantage of such a design is that when the support beam 40 of the energy storage container is in use and is subjected to external forces in the direction of gravity, the web 43 can decompose these external forces into forces downward in the direction of gravity and forces along the length direction of the web 43, thereby helping to alleviate the degree of deformation of the web 43 toward the bottom side 110, and ultimately achieving the improvement of the carrying capacity of the energy storage container.

[0065] Continuing to refer to Figures 3, 4, and 17, to further enhance the strength of the support beam 40, in addition to the web 43 described above, the support beam 40 may also include a first wing 41. The first edge of the web 43 is connected to the first wing 41, and the web 43 and the first wing 41 are not coplanar. Specifically, both web ends 431 are connected to the first wing 41, and the web middle portion 432 is spaced apart from the first wing 41. Each battery rack 20 may include a first crossbar 21 disposed on the bottom side 110, with a first wing 41 connecting each first crossbar 21. Exemplarily, part of the first cross bar 21 may include a first sub-cross bar and a second sub-cross bar, the first sub-cross bar being connected between the first cross beam 121 and the first wing plate 41, and / or the second sub-cross bar being connected between the second cross beam 122 and the first wing plate 41, each first sub-cross bar and each second sub-cross bar may include an end face facing the web 43 and a side face facing the first wing plate 41, between the first cross beam 121 and the first wing plate 41, an end of the first sub-cross bar close to the web 43 can be welded to the web 43, and / or, a side of the first sub-cross bar facing the first wing plate 41 can be welded to the first wing plate 41, between the second cross beam 122 and the support beam 40, an end of the second sub-cross bar close to the web 43 can be welded to the web 43, and / or, a side of the second sub-cross bar facing the first wing plate 41 can be welded to the first wing plate 41.

[0066] 4 and 9 , the crossbeams of the frame 10 may further include a fifth crossbeam 125 and a sixth crossbeam 126 , which are respectively disposed at opposite ends of the bottom side 110 along the length of the support beam 40 and / or are respectively connected to opposite ends of the first wing panel 41 . Specifically, referring to FIG3 , in some embodiments of the present application, along the length of the support beam 40 , the frame 10 may further include a first end 150 and a second end 160 , which are oppositely disposed. The fifth crossbeam 125 is disposed at the connection between the bottom side 110 and the first end 150 , and the sixth crossbeam 126 is disposed at the connection between the bottom side 110 and the second end 160 . One end of the first wing panel 41 is connected to the fifth crossbeam 125 , and the other end of the first wing panel 41 is connected to the sixth crossbeam 126 . It is understood that the ends of the first wing panel 41 can be connected to the fifth crossbeam 125 and the sixth crossbeam 126 respectively by welding, or can also be connected to the fifth crossbeam 125 and the sixth crossbeam 126 respectively by threading. This application does not impose any restrictions on the specific connection method between the first wing panel 41 and the fifth crossbeam 125 and the sixth crossbeam 126. The support beam provided in the embodiment of the present application is conducive to improving the connection strength between the various components constituting the energy storage container 1 by connecting the ends of its first wing panel 41 to the fifth crossbeam 125 and the sixth crossbeam 126 at the two ends of the energy storage container 1, thereby improving the carrying capacity of the energy storage container 1.

[0067] The web 43 may further include a second side proximate to the top side 120, and the support beam 40 may further include a second wing 42, one side of the second wing 42 being connected to the second side, and the web 43 and the second wing 42 being arranged non-coplanarly. In some optional embodiments of the present application, the second side of the web 43 and the second wing 42 may be welded together. When the support beam 40 is assembled to the bottom side 110 of the frame 10, the first wing 41 and the second wing 42 may be disposed on either side of the first crossbar 21, wherein the first wing 41 is disposed on the side of the first crossbar 21 facing away from the top side 120, and the second wing 42 is disposed on the side of the first crossbar 21 facing away from the first wing 41, and the web 43 is connected between the first wing 41 and the second wing 42.

[0068] Referring to Figures 3, 4, and 9, multiple battery racks 20 are spaced apart along the length of the support beam 40. In some embodiments, the multiple battery racks 20 include two first battery racks 210 located at opposite ends of the second wing 42. Each first battery rack 210 may include a third crossbar 25 located near the bottom side 110, with the ends of the second wing 42 respectively connected to the third crossbar 25 of a first battery rack 210. Specifically, in each first battery rack 210, the third crossbar 25 is spaced apart between the first crossbar 21 and the second crossbar 22. One end of the second wing 42 is connected to the third crossbar 25 of a first battery rack 210, and the other end of the second wing 42 is connected to the third crossbar 25 of another first battery rack 210. By connecting the ends of the second wing 42 to the third crossbar 25 at the opposite ends of the energy storage container 1, the embodiment of the present application facilitates improving the connection strength between the various components of the energy storage container 1, thereby increasing the carrying capacity of the energy storage container.

[0069] Please continue to refer to Figures 4 and 9. In some embodiments, the frame 10 may further include two first columns 14, each first column 14 is connected between the bottom side 110 and the top side 120, and along the length direction of the web 43, one first column 14 is connected to one end of the web 43, and the other first column 14 is connected to the other end of the web 43. Specifically, the crossbeams of the frame 10 may also include a seventh crossbeam 127 and an eighth crossbeam 128. The seventh crossbeam 127 is arranged at the connection between the first end 150 and the top side 120, and the eighth crossbeam 128 is arranged at the connection between the second end 160 and the top side 120. At the first end 150, a first column 14 can be connected between the fifth crossbeam 125 and the seventh crossbeam 127. One end of the web 43 can be connected to an end of a first column 14 close to the bottom side 110 by welding. At the second end 160, another first column 14 can be connected between the sixth crossbeam 126 and the eighth crossbeam 128, or connected between the third crossbeam 25 and the sixth crossbeam 126. Similarly, the other end of the web 43 can be connected to an end of another first column 14 close to the bottom side 110 by welding. It can be understood that in some other embodiments, the two ends of the web 43 can also be connected to the two first columns 14 respectively by other suitable connection methods (such as threaded connection). In the embodiment of the present application, by connecting the two ends of the web 43 to the two first columns 14 at the two ends of the energy storage container 1 respectively, it is beneficial to improve the connection strength between the various components of the energy storage container 1, thereby improving the carrying capacity of the energy storage container.

[0070] To facilitate those skilled in the art to better understand the structure of the support beam provided in the embodiments of the present application, the assembly process and implementation principle of one of the support beams provided in the embodiments of the present application are schematically described here. In some embodiments of the present application, at least a portion of the first side of the web can be an arcuate side, the second side of the web can be a straight side, and at least a portion of the first side is bent toward the second side. For example, the middle portion of the web of the first side of the web can be formed into an arcuate side toward the top side, so that the distance between the first side of the web and the second side of the web includes a first distance between the middle portion of the first side and the second side, and a second distance between the end portion of the first side and the second side. After testing, the inventor found that when the difference between the first distance and the second distance is 15mm-25mm, that is, when the maximum spacing between the middle portion of the web and the first wing is 15mm-25mm, the support beam can achieve optimal stiffness and strength, thereby enabling the energy storage container to have the best load-bearing capacity. In the example of connecting the web to the first wing plate and the second wing plate in sequence, the two end portions of the first side of the web plate can be firstly abutted against the surface of the first wing plate. In this case, a gap can be observed to be formed between the middle of the web plate and the surface of the first wing plate. Then, solder can be filled into the gap so that the first side of the web plate and the first wing plate can be connected by a welding process. Afterwards, the second side of the web plate is abutted against the surface of the second wing plate. Then, solder is applied near the abutting position between the second side of the web plate and the second wing plate so that the second side of the web plate and the second wing plate can also be connected by a welding process. In some embodiments, the web plate, the first wing plate, and the second wing plate can be arranged orthogonally or nearly orthogonally to each other so that the support beam has an "I"-shaped cross-section perpendicular to its length direction. Practice has shown that this support beam with an "I"-shaped cross-section has better rigidity and strength. During actual use, when the support beam is subjected to force in the direction of gravity, the web can decompose these forces into force in the direction of gravity and force along the length of the support beam, thereby alleviating the degree of deformation of the support beam toward the bottom side under the action of external force. Since a gap is formed between the middle part of the web and the surface of the first wing plate, and the strength of the solder used for welding the web and the first wing plate in the embodiment of the present application is less than the strength of the web, when the support beam is subjected to a larger force in the direction of gravity, the middle part of the web can also move toward the direction of the first wing plate, and finally the middle part of the web is completely in contact with the first wing plate, which can effectively limit the deformation of the web.

[0071] In the embodiment of the present application, the support beam 40 is pre-arc-edged before being put into use, and the support beam 40 is connected to each battery rack 20. Compared with the support beam 40 without the arc-edged process, the advantage of this design is that when the support beam 40 is subjected to an external force in the direction of gravity, the ability of the support beam 40 to deform toward the bottom side 110 can be effectively reduced, thereby greatly improving the stiffness and strength of the support beam 40, thereby effectively improving the carrying capacity of the energy storage container 1 and extending the service life of the energy storage container 1.

[0072] 4 , 9 , and 14 , at least one battery rack 20 may further include a support member 26 , and each support member 26 connects the second wing 42 , the bottom side 110 , the top side 120 , the first side 130 , and the second side 140 . Specifically, both ends of the first crossbar 21 , the second crossbar 22 , and the third crossbar 25 are connected between the first side 130 and the second side 140 . Each support member 26 may include a support body, a first support rod 261 , a second support rod 262 , a third support rod 263 , and a fourth support rod 264 . The support body is connected between the second crossbar 22 and the third crossbar 25 , or the support body connects the first crossbar 21 , the second crossbar 22 , and the third crossbar 25 , and the first support rod 261 , the second support rod 262 , the third support rod 263 , and the fourth support rod 264 . 2. One end of the third support rod 263 and the fourth support rod 264 can be connected to the middle part of the support body, the other end of the first support rod 261 and the other end of the second support rod 262 can be respectively connected to the two ends of the third cross bar 25, and the other end of the third support rod 263 and the other end of the fourth support rod 264 can be respectively connected to the two ends of the second cross bar 22, thereby enabling each support member 26 to be connected to the second wing plate 42, the bottom side 110, the top side 120, the first side 130 and the second side 140. In some embodiments, each supporting body may include at least two second columns 265 and a first connecting rod 266, each second column 265 is connected to the first cross bar 21, the second cross bar 22 and the third cross bar 25, or, each second column 265 is connected to the first cross bar 21 and the third cross bar 25, the two second columns 265 are arranged at intervals, and the first connecting rod 266 is connected between at least two second columns 265, one of the second columns 265 is arranged close to the first side and connected to the first support rod and the third support rod, and the other second column 265 is arranged close to the second side and connected to the second support rod and the fourth support rod. It is understood that the support body may also include only a second column 265 without the first connecting rod 266. In this embodiment, the second column 265 connects the first crossbar 21, the second crossbar 22, and the third crossbar 25, or the second column 265 connects the second crossbar 22 and the third crossbar 25, and the second column 265 connects the first support rod 261, the second support rod 262, the third support rod 263, and the fourth support rod 264. When the energy storage container 1 is subjected to force, the first crossbar 21, the second crossbar 22, the third crossbar 25, the first support rod 261, the second support rod 262, the third support rod 263, and the fourth support rod 264 can transmit the force applied to the energy storage container 1 from multiple directions (e.g., from the bottom, the top, the first side, and the second side) to the support body, which then transmits the force to the support beam 40. Therefore, the support member 26 can further improve the structural strength of the frame 10 and extend the service life of the energy storage container 1.

[0073] Referring to FIG. 4 , in some embodiments, the frame 10 may further include a plurality of second connecting rods 16. Multiple second connecting rods 16 may be connected between the first wing plate 41 and the first crossbeam 121, and between the first wing plate 41 and the second crossbeam 122. The plurality of second connecting rods 16 are spaced apart along the length of the support beam 40. Specifically, between the support beam 40 and the first crossbeam 121, one end of the second connecting rod 16 may be connected to the first crossbeam 121, and the other end of the second connecting rod 16 may be connected to the first wing plate 41. Between the support beam 40 and the second crossbeam 122, one end of the second connecting rod 16 may be connected to the second crossbeam 122, and the other end of the second connecting rod 16 may be connected to the first wing plate 41. The frame 10 provided in the embodiment of the present application can disperse the force applied to the frame 10 to the support beam 40, the first crossbeam 121, and the second crossbeam 122 through the second connecting rods 16, by means of a plurality of second connecting rods 16 spaced apart between the first wing plate 41 and the first crossbeam 121, and spaced apart between the first wing plate 41 and the second crossbeam 122. This can effectively improve the overall rigidity and strength of the frame 10, and ultimately achieve the effect of improving the carrying capacity of the energy storage container 1.

[0074] The energy storage container 1 may further include a partition (not shown), a bottom plate, a top plate 33 , a first side plate 311 , a second side plate, a third side plate, a first fireproof layer, and a second fireproof layer. Among them, the partition connects the frame 10 and can be used to separate the internal space of the frame 10 into a first compartment and a second compartment. For example, in some embodiments, the partition can be arranged perpendicular to the length direction of the first beam 121 to separate the internal space of the frame 10 into a first compartment and a second compartment. The first compartment can be used to install a battery pack, and at least part of the space of the second compartment can be used as an electrical compartment for installing electrical equipment. The bottom plate is arranged on the bottom side 110, the top plate 33 is arranged on the top side 120, the first side plate 311 is arranged on the first side 130, the second side plate and the third side plate can both be arranged on the second side 140, and the first side plate 311 is arranged opposite to the third side plate, and the second side plate is arranged opposite to multiple first compartment doors.

Referring to Figure 17, the support beam 40 includes a first wing 41, a second wing 42, and a web 43. The web 43 is connected between the first wing 41 and the second wing 42. Before the entire support beam 40 is assembled on the frame 10, the first edge of the web 43 used for connection with the first wing 41 must be designed as an arcuate edge. Referring to Figures 4 and 9, the first wing 41 connects to the first crossbar 21 of each battery rack 20. At least two battery racks 20 may also include a third crossbar 25 disposed between the first crossbar 21 and the second crossbar 22. The second wing 42 of the support beam 40 has two ends connected to the two third crossbars 25. The ends of the web 43 of the support beam 40 are respectively connected to the two first columns 14 located at the ends of the frame 10. This allows the forces acting on the energy storage container 1 to be transmitted to the support beam 40. When the battery rack 20 selected to have a third cross bar 25 is located at the first end and / or second end of the frame, taking the case where the battery rack 20 is located at the second end 160 as an example, in this case, in order to reduce the reuse of cross bars or beams and simplify the frame structure design, the first cross bar 21 of the battery rack 20 can also be used as the sixth cross bar 126, and the second cross bar 22 of the battery rack 20 can also be used as the eighth cross bar 128.

[0088] Continuing with reference to Figures 4 and 9 , the two battery racks 20 connected to the second wing 42 of the support beam 40 may each be provided with a support member 26. Each support member 26 connects the support beam 40, the bottom side 110, the top side 120, the first side 130, and the second side 140. Each support member 26 may include a support body, a first support rod 261, a second support rod 262, a third support rod 263, and a fourth support rod 264. The support body may be connected between the second and third crossbars, or may connect the first, second, and third crossbars. One end of the first support rod 261, the second support rod 262, the third support rod 263, and the fourth support rod 264 is connected to the middle of the support body. The other end of the first support rod 261 and the other end of the second support rod 262 are respectively connected to the opposite ends of the third crossbar 25. The other end of the third support rod 263 and the other end of the fourth support rod 264 are respectively connected to the opposite ends of the second crossbar 22. When the energy storage container 1 is subjected to force, the first support rod 261, the second support rod 262, the third support rod 263 and the fourth support rod 264 can respectively transmit the force on each side of the energy storage container to the support body, and the support body then transmits the force to the support beam 40. This can help improve the stability and structural strength of the frame 10, thereby extending the service life of the energy storage container 1.

[0089] In summary, the beneficial effects of the energy storage container provided by the embodiment of the present application are: first, by arranging a storage space for accommodating at least part of the battery rack, an installation space for installing the rotating connector 34, and a storage space for accommodating the pipe in the corner column, it is beneficial to improve the structural compactness of the energy storage container; second, by recessing part of the wall of the first crossbeam along its length direction to form a storage groove, the storage groove can accommodate the bottom end of the locking rod of the warehouse door, which can further improve the structural compactness of the energy storage container; third, by processing the first side of the web of the support beam into an arc edge before it is put into use, and connecting the support beam to each battery rack so that there is no contact with the web. Compared with the support beam with curved edge processing, the advantage of this design is that when the support beam is subjected to external force in the direction of gravity, the ability of the support beam to deform toward the bottom side can be effectively reduced, thereby greatly improving the stiffness and strength of the support beam, thereby effectively improving the carrying capacity of the energy storage container and extending the service life of the energy storage container; fourthly, by arranging support members on at least two battery racks, the support members are simultaneously connected to the support beam, the bottom side, the top side, the first side and the second side. When the energy storage container is subjected to force, the support members can transfer the force to the support beam. It can be seen that the support members can further improve the structural strength of the frame and extend the service life of the energy storage container.
