The modular container of the application is applied to the energy storage device, and the battery energy storage system can be integrated in the modular container, which helps to promote energy transformation, improve the flexibility and reliability of the power grid, and promote the wider use of renewable energy.

[0063] The modular container comprises six panel modules 1, a first connecting structure 2 and a second connecting structure 3. The six panel modules 1 can be connected to each other in a side-enclosing manner in six directions to form a cuboid-shaped box structure. The recessed corners 11 and the protruding corners 12 are matched between the splicing sides of any two adjacent panel modules 1. There are at least two alignment positions between different planes between the matched recessed corners 11 and the protruding corners 12, which have a limiting effect, reduce the dislocation of the panel modules 1 during assembly, and facilitate the connection and fastening of the first connecting structure 2 and the second connecting structure 3. At the same time, the first connecting structure 2 can be detachably connected to one side of the recessed corner 11 and the protruding corner 12, and the second connecting structure 3 can be detachably connected to the other side of the recessed corner 11 and the protruding corner 12, which facilitates the disassembly and assembly of the modular container. The side surfaces connected by the first connecting structure 2 and the second connecting structure 3 are located in different planes, so that the fastening of any two adjacent panel modules 1 in two directions is realized, and the connection strength and stability of the two adjacent panel modules 1 are improved. The application designs a high-capacity and movable modular container and an energy storage system with the modular container. Through the structure layout of the panel modules 1 which can be conveniently disassembled and modularized, the overseas transportation cost requirement can be met. The connection of the panel modules 1 by the first connecting structure 2 and the second connecting structure 3 makes the movable energy storage product of the modular container more stable and reliable.

[0064] For the convenience of description, the direction after the installation of the six panel modules 1 to form the box structure is taken as an example. The transverse direction is the left-right direction of the drawing, and the longitudinal direction is the front-rear direction of the drawing.

[0065] Figure 1 The structure diagram of the assembled modular container is shown in FIG. 1. Figure 1 The modular container comprises six panel modules 1, which are enclosed to form a box structure in the up, down, left, right, front and rear directions. Any two adjacent panel modules 1 are opposite to each other in the side direction, and the two adjacent panel modules 1 are perpendicular to each other.

[0066] Figure 2 is an assembled view of four plate modules 1. Figure 3 is a local enlarged view of the concave corner 11 and the convex corner 12 in the adjacent two plate modules 1. Figure 4 is a structural view of the adjacent two plate modules 1 after installation.

[0067] Referring to Figure 2 , Figure 3 and Figure 4 , the side of one plate module 1 is provided with a first plate segment 111 and a second plate segment 112, the side of the other plate module 1 is provided with a third plate segment 121 and a fourth plate segment 122, the first plate segment 111 and the second plate segment 112 are in different planes, the first plate segment 111 and the second plate segment 112 intersect to form a concave corner 11, the third plate segment 121 and the fourth plate segment 122 are in different planes, the third plate segment 121 and the fourth plate segment 122 intersect to form a convex corner 12, as shown in Figure 4 , the concave corner 11 on one plate module 1 and the convex corner 12 on the other plate module 1 are concave-convex matched, so that the first plate segment 111 is opposite to the third plate segment 121, and the second plate segment 112 is opposite to the fourth plate segment 122.

[0068] When the adjacent two plate modules 1 are spliced with each other, the concave corner 11 on one plate module 1 and the convex corner 12 on the other plate module 1 can be concave-convex matched, which facilitates the alignment between the two plate modules 1, and the first plate segment 111 and the second plate segment 112 intersecting on the concave corner 11 can be respectively opposite to the third plate segment 121 and the fourth plate segment 122 intersecting on the convex corner 12 in a plane by plane manner, which further reduces the misalignment of the adjacent two plate modules 1 during the assembly process, and facilitates the subsequent connection and fastening of the two plate modules 1.

[0069] Further, between the adjacent two plate modules 1, the side of one plate module 1 is a first connecting beam 13, and the side of the other plate module 1 is a second connecting beam 14. The first connecting beam 13 and the second connecting beam 14 can abut against each other.

[0070] Specifically, the first connecting beam 13 comprises a first mounting sheet metal 131, which is an integral structure; the first mounting sheet metal 131 comprises a first stepped segment 1311 and a second stepped segment 1312 connected in sequence, the first stepped segment 1311 and the second stepped segment 1312 are both formed into an L-shaped structure by two mutually perpendicular plate surfaces, and the first stepped segment 1311 and the second stepped segment 1312 are connected in sequence to form a two-step structure. Among them, the plate surface of the second stepped segment 1312 connecting the first stepped segment 1311 is the first plate segment 111, and the plate surface of the first stepped segment 1311 connecting the second stepped segment 1312 is the second plate segment 112.

[0071] The second connecting beam 14 comprises a second mounting sheet metal 141 which is an integral structure.

The third stepped section 1411 and the fourth stepped section 1412 are both formed into an L-shaped structure by two mutually perpendicular plate surfaces. The third stepped section 1411 and the fourth stepped section 1412 are connected in sequence to form a two-step stepped structure. The plate surface of the third stepped section 1411 connecting the fourth stepped section 1412 is a fourth plate section 122. The other plate surface of the third stepped section 1411 away from the fourth stepped section 1412 is a third plate section 121.

[0072] The first mounting sheet metal 131 comprises a first stepped section 1311 and a second stepped section 1312 connected in sequence to form a two-step stepped structure. The first stepped section 1311 and the second stepped section 1312 are recessed at the connecting position to form a concave corner 11. The first plate section 111 and the second plate section 112 are located on the stepped surface of the first mounting sheet metal 131 to improve the structural strength of the first connecting beam 13.

[0073] The second mounting sheet metal 141 comprises a third stepped section 1411 and a fourth stepped section 1412 connected in sequence to form a two-step stepped structure. The third plate section 121 and the fourth plate section 122 intersect to form a convex corner 12, thereby constituting the third stepped section 1411 to improve the structural strength of the second connecting beam 14.

[0074] The concave corner 11 and the convex corner 12 of the present application are matched in a stepped structure to improve the structural strength of the first connecting beam 13 and the second connecting beam 14, and to make the alignment and matching of the first connecting beam 13 and the second connecting beam 14 more stable. The length direction of the concave corner 11 and the convex corner 12 of the present application extends along the side edge of the plate module 1, so that the concave corner 11 and the convex corner 12 extend in a continuous strip shape to improve the contact area of the concave corner 11 and the convex corner 12 and the stability of the matching and connection of the concave corner 11 and the convex corner 12. In addition, the adjacent two plate modules 1 can be aligned and matched with each other by the plurality of concave corners 11 and the plurality of convex corners 12. The concave corner 11 and the convex corner 12 can also be matched and aligned in an intermittent manner.

The opposite two side edges of the first cover plate 132 are bent inward, and the inwardly bent side edges of the first cover plate 132 are welded to the inner walls of the first stepped section 1311 and the first extension section 1313, respectively. The first cover plate 132 further supports the first stepped section 1311 and the first extension section 1313, reduces the deformation of the first mounting sheet metal 131, and improves the structural strength of the first connecting beam 13.

Figure 9 The installation structure diagram of the end module 18 and the end opening 19. Referring to Figure 8 and Figure 9The end module 18 is embedded into the end opening 19 formed by the bottom plate module 15, the top cover module 17 and the two side modules 16. The end module 18 is positioned in the end opening 19 formed by the bottom plate module 15, the top cover module 17 and the two side modules 16 in advance, facilitating the installation of the end module 18. In the embodiment, the first protruding corner 151 of the bottom plate module 15, the second protruding corner 171 of the top cover module 17 and the third protruding corner 163 of the side module 16 form a protrusion 191 on the circumference of the end opening 19.

[0090] Referring to Figure 4 In order to improve the connection stability of the two adjacent plate modules 1, the first connecting structure 2 includes a plurality of first bolts 21 arranged along the periphery of the plate module 1. Specifically, the first bolt 21 penetrates the first plate segment 111 of one plate module 1 and the third plate segment 121 of another plate module 1, so that the two adjacent plate modules 1 can be connected and fastened. The plurality of first bolts 21 are arranged along the extending direction of the first plate segment 111 and the extending direction of the third plate segment 121, so as to increase the connection positions between the first plate segment 111 and the third plate segment 121, and improve the connection stability of the two adjacent plate modules 1. In addition, the first connecting structure 2 can also be a clamping member for clamping and fixing the first plate segment 111 and the third plate segment 121 to each other.

[0091] In the embodiment, the first bolt 21 is sequentially threaded through the first extension section 1313 of one panel module 1, the first plate section 111, and the third plate section 121 of another panel module 1, thereby improving the connection strength of the adjacent two panel modules 1.

[0093] With reference to Figure 9 For the connection between the end module 18 and the bottom plate module 15 and the top cover module 17, respectively, the first plate section 111 of the third concave corner 181 on the upper and lower sides, the third plate section 121 of the first convex corner 151, and the third plate section 121 of the second convex corner 171 all extend along the horizontal plane, and the first bolt 21 is vertically connected between the horizontally extending first plate section 111 and the third plate section 121.

[0094] With reference to Figure 10 For the connection between the end module 18 and the two side modules 16, the third plate section 121 of the third convex corner 163 and the first plate section 111 of the third concave corner 181 on the left and right sides all extend along the vertical plane, and the first bolt 21 is horizontally connected between the vertically extending first plate section 111 and the third plate section 121.

[0095] Further, the second connection structure 3 includes a plurality of second bolts 31 which are sequentially and spaced apart along the periphery of the panel module 1. Specifically, the second bolt 31 is threaded through the second plate section 112 of one panel module 1 and the fourth plate section 122 of another panel module 1, so that the adjacent two panel modules 1 can be connected and fastened, and the plurality of second bolts 31 are spaced apart along the extension direction of the second plate section 112 and the extension direction of the fourth plate section 122, thereby increasing the connection positions between the second plate section 112 and the fourth plate section 122 and further improving the connection stability of the adjacent two panel modules 1. In addition, the second connection structure 3 can also be a clamping member for clamping and fixing the second plate section 112 and the fourth plate section 122 to each other.

[0096] In the embodiment, the second bolt 31 can be threaded out from the first cover plate 132 or the second cover plate 142, and then threaded through the fourth plate section 122 of one panel module 1 and the second plate section 112 of another panel module 1, thereby improving the connection strength of the adjacent two panel modules 1.

[0097] With referenceFigure 2 and Figure 3 For the connection between the side module 16 and the bottom plate module 15, the top cover module 17 respectively, the second plate segment 112 of the first concave corner 161, the fourth plate segment 122 of the first convex corner 151, the second plate segment 112 of the second concave corner 162, and the fourth plate segment 122 of the second convex corner 171 all extend along the vertical plane, and the second bolt 31 is connected horizontally between the vertically extending second plate segment 112 and the fourth plate segment 122.

[0100] It can be seen that the first bolt 21 and the second bolt 31 connected between the two adjacent plate module 1 are perpendicular to each other, so that the connection strength and stability of the two adjacent plate module 1 are improved, and the mobile energy storage product is more stable and reliable. Moreover, the first bolt 21 and the second bolt 31 are used to connect the two adjacent plate module 1 in a detachable connection structure, which facilitates the installation and disassembly of the modular container to meet the overseas transportation cost requirements. In actual installation, the first bolt 21 and the second bolt 31 are staggered to avoid interference.

[0105] Specifically, in the side module 16 and the base plate module 15, the first sealing gasket 41 is horizontally laid between the first plate segment 111 of the first concave corner 161 and the third plate segment 121 of the first convex corner 151, and the side module 16 is vertically pressed and connected to the base plate module 15; in the side module 16 and the top cover module 17, the first sealing gasket 41 is horizontally laid between the first plate segment 111 of the second concave corner 162 and the third plate segment 121 of the second convex corner 171, and the top cover module 17 is vertically pressed and connected to the side module 16. As can be seen, the first sealing gasket 41 is stressed in the vertical direction, further improving the sealing of the side module 16 and the base plate module 15, and facilitating the installation of the first sealing gasket 41. In addition, the first sealing gasket 41 can be provided with a relief hole for the first bolt 21 to pass through in the front-rear direction, facilitating installation.

The second sealing gasket 42 can be directly fitted on the end module 18, facilitating the installation of the second sealing gasket 42.

[0109] Specifically, in the end module 18 and the bottom plate module 15, the second sealing gasket 42 is vertically laid between the second plate segment 112 of the third concave corner 181 and the fourth plate segment 122 of the first convex corner 151; in the end module 18 and the top cover module 17, the second sealing gasket 42 is vertically laid between the second plate segment 112 of the third concave corner 181 and the fourth plate segment 122 of the second convex corner 171; in the end module 18 and the side module 16, the second sealing gasket 42 is vertically laid between the second plate segment 112 of the third concave corner 181 and the fourth plate segment 122 of the third convex corner 163.

In addition, the second sealing gasket 42 can be provided with a plurality of avoiding holes for the second bolt 31 to pass through in the front-rear direction, which facilitates installation.

[0110] In addition, the annular second sealing gasket 42 can also be arranged around the outer periphery of the first plate segment 111 of the third concave corner 181, so that the second sealing gasket 42 is arranged between the first plate segment 111 of the third concave corner 181 and the fourth plate segment 122 on the protrusion 191.

[0111] In fact, the shape of the sealing gasket is related to the installation sequence of the plate module 1.

[0112] In some specific embodiments, the bottom plate module 15 is first laid flat, then two first sealing gaskets 41 are arranged on the left and right side edges of the bottom plate module 15 respectively, and two side modules 16 are connected to the two side edges of the bottom plate module 15 through a plurality of first bolts 21 and second bolts 31, so that the first sealing gaskets 41 seal the top surface of the side edges of the bottom plate module 15 and the bottom of the side modules 16; then another two first sealing gaskets 41 are arranged on the top of the two side modules 16, and the left and right side edges of the top cover module 17 are connected to the top of the two side modules 16 through the first bolts 21 and the second bolts 31 respectively, so that the first sealing gaskets 41 seal the top of the side modules 16 and the bottom surface of the side edges of the top cover module 17; at this time, the bottom plate module 15, the top cover module 17 and the two side modules 16 form two end openings 19, and two annular second sealing gaskets 42 are respectively sleeved around the periphery of the two end modules 18, then the end modules 18 are connected to the end openings 19 through the first bolts 21 and the second bolts 31, so that the second sealing gaskets 42 seal the four peripheries of the end modules 18, the front and rear side edges of the bottom plate module 15, the front and rear side edges of the side modules 16 and the front and rear side edges of the top cover module 17. At this time, the entire box structure is sealed by the twelve edges formed by the connection of the adjacent two plate modules 1. It can be seen that the sealing gaskets are arranged between the pressing surfaces of the two adjacent plate modules 1, which further improves the sealing performance of the two adjacent plate modules 1.

In fact, the corner piece 5 can be welded on the four corners of the floor module 15 and the four corners of the top cover module 17.
