Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figures 1 to 6 As shown, the energy storage container 100 of this utility model includes a container body 1, multiple energy storage modules 2, a combiner cabinet 3 for electrical connection with the multiple energy storage modules 2, a transformer 4, a firewall 5, a push-in closure 6, a protective cover 7, a support frame 8, a protective net 9, and a mounting beam 10.

[0027] The container body 1 includes a support frame 11, a bottom wall 12, and side walls. The side walls are omitted from the attached drawings.

[0028] The firewall 5 is disposed inside the container body 1, dividing the container body 1 into a first chamber 13 and a second chamber 14. In this embodiment, the firewall 5 extends along the width direction of the container body 1, dividing the container body 1 into a first chamber 13 and a second chamber 14 along the length direction.

[0029] Multiple energy storage modules 2 and the combiner cabinet 3 are located in the first chamber 13, and the transformer 4 is located in the second chamber 14.

[0030] like Figure 4 As shown, the firewall 5 includes a frame 51 and fireproof panels 52 filled between the frame 51. The fireproof panels 52 are located on the side of the frame 51 closer to the second chamber 14. In this embodiment, there are multiple fireproof panels 52. The firewall 5 is manufactured and installed in sections. After the frame 51 is installed, the fireproof panels 52 are installed sequentially.

[0031] The fireproof board 52 is positioned on the side of the frame 51 near the second chamber 14 and the transformer 4 to meet better fire protection requirements.

[0032] In this embodiment, the firewall 5 is provided with a connection window 53, and the transformer 4 and the combiner cabinet 3 are connected by plugging in the connection window 53.

[0033] like Figure 5 and Figure 6 As shown, the transformer 4 further includes a terminal block 41 and a flexible copper busbar 42 connected to the terminal block 41, and the busbar 3 includes a busbar 31. The terminal block 41 and the flexible copper busbar 42 are inserted into the first chamber 13 and electrically connected to the busbar 31.

[0034] In this embodiment, the terminal 41 of the transformer 4 is directly inserted into the first chamber 13, which shortens the connection distance and eliminates the need for rigid support. A soft copper busbar 42 can be used for connection, thus eliminating the need for bottom support of the terminal 41 and the soft copper busbar 42 and omitting the long-distance support structure specifically used to support the connecting cable or hard copper busbar.

[0035] The protective cover 7 includes a top cover 71 and side covers 72 extending downward from both sides of the top cover 71, and the protective cover 7 covers the busbar 31.

[0036] like Figures 4 to 6As shown, the push-in closure 6 surrounds the busbar 31 and is fixed to the firewall 5 to partially obscure the connection window 53. The push-in closure 6 is detachably mounted to the firewall 5. In this embodiment, the push-in closure 6 partially surrounds the busbar 31, particularly obscuring the top and sides of the busbar 31.

[0037] In this embodiment, before installing the transformer 4, the push-in sealing member 6 is removed. After installing the terminal 41, flexible copper busbar 42, and busbar 31, and installing the protective cover 7 on the busbar 31, the push-in sealing member 6 is installed laterally on the firewall 5, which serves to supplement the isolation of the first chamber 13 and the second chamber 14. In this embodiment, the push-in sealing member 6 is also made of a bracket and a fireproof plate 52.

[0038] By setting the push-in sealing member 6, more operating space is reserved before the transformer 4 is installed, and after the transformer 4 is installed, the connecting window 53 is sealed, thereby achieving a fireproof effect and fully isolating the first chamber 13 and the second chamber 14.

[0039] The push-in closure 6 is n-shaped, with both sides extending downwards. After the protective cover 7 is installed, the firewall 5 is installed from inside the second chamber 14 along the protective cover 7 and fixed to the firewall 5 with screws. This setup is simple to install, has low processing and procurement costs, and a short installation time.

[0040] The support frame 8 is disposed within the first chamber 13 and extends horizontally. Multiple energy storage modules 2 are fixed to the support frame 8, and the combiner cabinet 3 is located below the support frame 8. In this embodiment, the energy storage modules 2 and the combiner cabinet 3 are arranged vertically, allowing the surrounding area of ​​the combiner cabinet 3 to be fully exposed. This facilitates maintenance by technicians without requiring internal space for technicians to enter and perform repairs, making maintenance more convenient and reducing space requirements. Therefore, the energy storage container 100 of this patent application can accommodate all necessary components using the dimensions of a standard shipping container, reducing transportation costs.

[0041] In addition, in this embodiment, by setting up the combiner cabinet 3 at the bottom, more space is reserved at the bottom, and only one larger combiner cabinet 3 is needed to meet the requirements, further saving space and reducing costs.

[0042] The support frame 8 forms a U-shape with its opening facing the second chamber 14, and multiple energy storage modules 2 are arranged sequentially on the support frame 8, also forming a U-shape with their openings facing the second chamber 14. In this embodiment, a row of energy storage modules 2 is arranged on one side along the length direction, which makes better use of the length space, resulting in a more reasonable layout and further reducing the volume occupied.

[0043] The protective net 9 is installed on the top of the container body 1 to cover the top of the first chamber 13.

[0044] The mounting beam 10 is disposed on the top of the container body 1 to cover the top of the second chamber 14. The mounting beam 10 is detachable. The energy storage container 100 has a normal state with the mounting beam 10 installed and a state ready to be installed with the mounting beam 10 removed. When the energy storage container 100 is in the ready-to-be-installed state, the top of the second chamber 14 is exposed to accommodate the transformer 4.

[0045] The energy storage container 100 of this utility model makes full use of the space inside the container body 1 through a reasonable layout, and can use a standard-sized container, thus reducing transportation costs; and by setting a firewall 5 and setting a connection window 53 on the firewall 5 to connect the transformer 4 and the combiner cabinet 3, the distance between the transformer 4 and the low-voltage combiner cabinet 3 is shortened, the support structure is eliminated, the cost is lower, and the installation is simpler.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
