[0049] Referring to Figures 1 to 5, a battery energy storage container system provided in an embodiment of the present application includes a container 100, a plurality of battery packs 200, a high-voltage box assembly 300, and an electrical cabinet (in one embodiment, the electrical cabinet is a junction cabinet 410). The container 100 includes a battery compartment 110 and an equipment compartment 120 arranged along a first direction, wherein the battery compartment 110 includes a first cavity 111 and a second cavity 112 that are interconnected, the second cavity 112 is located between the first cavity 111 and the equipment compartment 120, and at least part of the battery pack 200 is disposed in the first cavity 111. The high-voltage box assembly 300 includes a plurality of high-voltage boxes 311, and the high-voltage box assembly 300 is installed in the second cavity 112. The electrical cabinet is installed in the equipment compartment 120, and the electrical cabinet partially extends into the second cavity 112.

[0050] In the above embodiment, the high-voltage box 311 is all installed in the second cavity 112, but not in the first cavity 111, so as to make room for the first cavity 111, so that it can have more space to install the battery pack 200. When there are a large number of battery packs 200, the second cavity 112 may not be occupied or may be occupied less, so that more space is left in the second cavity 112, so that part of the electrical cabinet can be located in the equipment compartment 120, and part of it can extend into the second cavity 112, so as to realize the installation of the electrical cabinet in the container 100. In summary, by rearranging the installation positions of the battery pack 200 and the high-voltage box 311, at least part of the battery pack 200 is concentrated, and the high-voltage box 311 is concentrated, so that the originally scattered remaining space in the entire battery compartment 110 is concentrated in the second cavity 112, and space is reserved for the installation of the electrical cabinet in the container 100, so as to realize the built-in of the electrical cabinet, and facilitate the storage, transportation and assembly of the electrical cabinet and the container 100 as a whole.

[0051] 1 , in some embodiments, the electrical cabinet is a combiner cabinet 410. In other embodiments, the electrical cabinet may also be other similar cabinets.

[0052] Referring to Figures 1 to 5, in some embodiments, the second cavity 112 includes an avoidance space 1121 located on one side of the high-voltage box assembly 300 along the second direction, the second direction, the first direction and the height direction of the container 100 are perpendicular to each other, and the electrical cabinet partially extends into the avoidance space 1121.

[0053] In the above embodiment, all high-voltage boxes 311 are centrally installed in the second cavity 112, but not in the first cavity 111, so as to free up space for the first cavity 111, so that it is mainly used for the centralized installation of the battery pack 200. Compared with the prior art in which the high-voltage boxes 311 are dispersedly arranged in the entire battery compartment 110, resulting in a small space on one side of each high-voltage box 311 along the second direction, which cannot be effectively utilized, in the present application, the centralized arrangement of the high-voltage boxes 311 makes the space on one side along the second direction also concentrated together to form a larger avoidance space 1121, so that a part of the electrical cabinet (combiner cabinet 410) can be located in the equipment compartment 120, and a part of it can extend into the avoidance space 1121, so as to realize the installation of the electrical cabinet (combiner cabinet 410) in the container 100. In summary, in the embodiment of the present application, by rearranging the installation positions of the battery pack 200 and the high-voltage box 311, at least part of the battery pack 200 is concentrated, and the high-voltage box 311 is concentrated, so that the originally scattered remaining space in the entire battery compartment 110 is concentrated in the second cavity 112, forming a larger avoidance space 1121, and reserving space for the installation of the electrical cabinet (combination cabinet 410) in the container 100, thereby realizing the built-in electrical cabinet (combination cabinet 410), facilitating the storage, transportation and assembly of the electrical cabinet (combination cabinet 410) and the container 100 as a whole.

[0054] In the drawings, the left-right direction is the first direction, the front-back direction is the second direction, and the up-down direction is the height direction of the container 100. In the subsequent embodiments, the description will be carried out with the aid of the perspectives shown in the drawings.

[0055] Further, in the embodiment shown in the drawings, the first direction is the length direction of the container 100, and the second direction is the width direction of the container 100. In other embodiments, the first direction may also be the width direction of the container 100, and correspondingly, the second direction is the length direction of the container 100.

[0056] From the perspective of the accompanying drawings, the first cavity 111, the second cavity 112 and the equipment compartment 120 are arranged from left to right. The high-voltage box assembly 300 is located relatively forward in the second cavity 112, and the avoidance space 1121 is located at the rear side of the high-voltage box assembly 300. Correspondingly, the electrical cabinet (combiner cabinet 410) is arranged in the rear space of the equipment compartment 120 and partially extends into the avoidance space 1121. Of course, in other embodiments, it can also be set that the high-voltage box assembly 300 is located relatively backward in the second cavity 112, and the avoidance space 1121 is located at the front side of the high-voltage box assembly 300. Correspondingly, the electrical cabinet (combiner cabinet 410) is arranged in the front space of the equipment compartment 120 and partially extends into the avoidance space 1121. The first cavity 111, the second cavity 112 and the equipment compartment 120 can also be arranged from right to left.

[0057] 1 to 3 , in some embodiments, part of the battery pack 200 is installed in the first cavity 111 , and part of the battery pack 200 is installed in the second cavity 112 .

[0058] The first cavity 111 is filled with battery packs 200, that is, the entire space in the first cavity 111 is used to centrally install the battery packs 200. In addition, by also arranging some battery packs 200 in the second cavity 112, the space can be fully utilized as much as possible, so that the number of battery packs 200 is larger, thereby having a higher energy density.

[0059] Referring to FIG. 1 and FIG. 2 , in some embodiments, the volume ratio of the avoidance space 1121 to the second cavity 112 is m, 6.5%≤m≤19.5%. When m satisfies the above range, a larger number of battery packs 200 can be arranged in the second cavity 112 to improve the energy density, while taking into account the installation of the high-voltage box assembly 300 and the avoidance and accommodation of the electrical cabinet (combiner cabinet 410).

[0060] Preferably, m is 13%. When m meets this value, the number of battery packs 200 in the second cavity 112 can be increased to the maximum extent, thereby greatly improving the energy density, while taking into account the installation of the high-voltage box assembly 300 and the avoidance and accommodation of the electrical cabinet (combiner cabinet 410).

[0061] In some embodiments, the ratio of the volume of the electrical cabinet (combiner cabinet 410 ) extending into the avoidance space 1121 to the total volume of the electrical cabinet (combiner cabinet 410 ) is n, where n≥0.4.

[0062] When n satisfies the above range, the volume of the electrical cabinet (combiner cabinet 410) accommodated in the avoidance space 1121 and the volume accommodated in the equipment compartment 120 can be better balanced, so that when the electrical cabinet (combiner cabinet 410) is built into the container 100, it will not affect the installation of other components in the second cavity 112 and the equipment compartment 120, thereby improving space utilization.

[0063] Preferably, n is 0.5. When n meets this value, the volume of the electrical cabinet (combiner cabinet 410) contained in the avoidance space 1121 and the volume contained in the equipment compartment 120 can be better balanced, so that when the electrical cabinet (combiner cabinet 410) is built into the container 100, more battery packs 200 can be installed in the second cavity 112, while taking into account the installation of the high-voltage box assembly 300. In addition, it can not affect the installation of other components in the equipment compartment 120, thereby improving space utilization.

[0064] 1 to 3 , in some embodiments, the battery energy storage container system further includes a storage box 420 , which is installed in the second cavity 112 .

[0065] In the above embodiment, the storage box 420 is installed in the second cavity 112, which can facilitate the storage of some disassembly and assembly tools. During transportation or storage, these tools are directly stored in the storage box 420, which is convenient for taking when in use.

[0066] 1 to 5 , in some embodiments, some battery packs 200 are arranged in the second cavity 112 along the height direction of the container 100 to form a second battery pack row 220 , and the storage box 420 is installed between the second battery pack row 220 and the high-voltage box assembly 300 .

[0067] In the above embodiment, the second battery pack array 220 and the high voltage box assembly 300 are arranged at intervals, so that a space is left between the two to install the storage box 420, which can make more effective use of the space.

[0068] Furthermore, the second battery pack array 220 is located above the storage box 420 , and the high voltage box assembly 300 is located below the storage box 420 .

[0069] In the embodiment shown in the drawings, the second battery pack column 220 includes five battery packs 200 arranged along the height direction of the container 100. The high-voltage box assembly 300 is located relatively low in the second cavity 112, and the second battery pack column 220 is located relatively high in the second cavity 112. The empty space between the two can be used to install the storage box 420 and the fire controller 464. Correspondingly, the position of the avoidance space 1121 is also relatively low, and the electrical cabinet (combiner cabinet 410) is arranged in the bottom space of the equipment compartment 120 and partially extends into the avoidance space 1121. In this way, it is only necessary to push the electrical cabinet (combiner cabinet 410) from the bottom space of the equipment compartment 120 into the avoidance space 1121, which can facilitate the installation of electrical cabinets (combiner cabinets 410) with heavier weight.

[0070] In other embodiments, the positions of the high-voltage box assembly 300 and the second battery pack array 220 may be interchanged, that is, the high-voltage box assembly 300 is located relatively high in the second cavity 112, and the second battery pack array 220 is located relatively low in the second cavity 112. Correspondingly, the position of the avoidance space 1121 is also relatively high, and the electrical cabinet (combiner cabinet 410) is arranged in the top space of the equipment compartment 120 and partially extends into the avoidance space 1121.

[0071] 1 to 5 , in some embodiments, the high voltage box assembly 300 includes a plurality of groups of high voltage box units 310 arranged along the height direction of the container 100 , and each group of high voltage box units 310 includes a plurality of high voltage boxes 311 arranged along a first direction.

[0072] By arranging multiple high-voltage boxes 311 in the same row, the space of the second cavity 112 along the first direction can be more fully utilized, thereby minimizing the space occupied by the high-voltage box assembly 300 in the height direction of the container 100, thereby increasing the space between the high-voltage box assembly 300 and the second battery pack array 220, thereby freeing up more space for the installation of the storage box 420.

[0073] 1 to 5 , in some embodiments, the high voltage boxes 311 in each set of high voltage box units 310 are connected as one body.

[0074] Specifically, the high-voltage boxes 311 in each group of high-voltage box units 310 share a common outer shell to form a whole. Since multiple high-voltage boxes 311 are arranged in the same row, the size of the high-voltage box unit 310 along the first direction will inevitably be larger. When these high-voltage boxes 311 are connected as a whole, the size of the high-voltage box unit 310 along the first direction can be reduced as much as possible so that it does not exceed the size of the second cavity 112 along the first direction, thereby achieving smooth installation of the high-voltage box unit 310 in the second cavity 112, so as to prevent the high-voltage box unit 310 from being too large in the first direction and unable to fit into the second cavity 112. In this way, the space between the high-voltage box assembly 300 and the second battery pack column 220 can be increased while satisfying the requirement that the high-voltage box unit 310 is installed in the second cavity 112.

[0075] 1 to 5 , in some embodiments, each high voltage box unit 310 includes two high voltage boxes 311 , and the size of the high voltage box 311 along the first direction is a, and the size along the second direction is b, and the range of a / b is 1.3-1.8.

[0076] It can be understood that if the size of the high-voltage box 311 along the second direction is set larger, as many of the components therein as possible can be arranged along the second direction, thereby reducing the demand for the space of the high-voltage box 311 along the first direction, so that the size of the high-voltage box 311 along the first direction can be minimized as much as possible, and the high-voltage box unit 310 can be smoothly installed in the second cavity 112, so as to prevent the size of the high-voltage box unit 310 along the first direction from being too large to fit into the second cavity 112. When the size of the high-voltage box 311 along the first direction and the second direction meets the above range, the size of the high-voltage box 311 along the first direction can be well reduced, and the high-voltage box unit 310 can be smoothly installed in the second cavity 112, while the size of the avoidance space 1121 will not be excessively compressed, and the electrical cabinet (combination cabinet 410) can be smoothly inserted.

[0077] 1 to 5 , in some embodiments, the electrical components in each high-voltage box 311 are arranged in at least two layers along the height direction of the container 100 .

[0078] Specifically, each high-voltage box 311 is provided with at least two layers of mounting racks arranged along the height direction of the container 100, and some electrical components are installed on each layer of mounting racks. The type of electrical components is not limited. Alternatively, each high-voltage box 311 is provided with at least two layers of circuit boards arranged along the height direction of the container 100, and some other electrical components other than circuit board types are installed on each layer of circuit boards. In this case, the circuit boards not only serve as electrical components, but also serve as mounting racks.

[0079] In this way, the space of the high-voltage box 311 along the height direction of the container 100 can be more fully utilized, thereby minimizing the size of the high-voltage box 311 along the first direction, and achieving smooth installation of the high-voltage box unit 310 in the second cavity 112, so as to prevent the high-voltage box unit 310 from being too large along the first direction and being unable to fit into the second cavity 112.

[0080] 5 to 7 , in some embodiments, the storage box 420 is slidably connected to the battery compartment 110 along the second direction, and the storage box 420 has a locking member 421 for locking with the battery compartment 110 .

[0081] Specifically, a slide rail 423 is provided at the bottom or side of the storage box 420, which is used to cooperate with a slide groove or a slider installed in the second cavity 112 to achieve sliding installation of the storage box 420. The storage box 420 can slide along the second direction to achieve the access of items. The locking member 421 can be locked with a member provided on the cavity wall of the second cavity 112, so that the position of the storage box 420 is locked after being pushed into the second cavity 112, so as to prevent the storage box 420 from sliding out along the second direction during transportation.

[0082] 5 and 6 , in some embodiments, two fixed rings 422 arranged at intervals are disposed in the storage box 420 , and two ends of the binding belts are respectively bound to the two fixed rings 422 .

[0083] Specifically, the two fixing rings 422 are respectively fixed on the two inner side walls of the storage box 420 which are arranged opposite to each other. After the items are put into the storage box 420, the two ends of the binding belt are respectively tied and fixed to the two fixing rings 422, so that the position of the items can be restrained, making it difficult for them to shake and shift at will in the storage box 420, so that they are not easily damaged by colliding with the inner wall of the storage box 420 due to severe shaking during transportation.

[0084] Preferably, multiple sets of matching fixing rings 422 can be provided to further optimize the effect of limiting the position of the objects.

[0085] 1 to 3 , in some embodiments, some battery packs 200 are arranged along the height direction of the container 100 to form a first battery pack row 210 , and a plurality of first battery pack rows 210 are arranged in the first cavity 111 along a first direction.

[0086] Specifically, in the embodiment shown in the drawings, three groups of first battery pack columns 210 arranged along the first direction are provided in the first cavity 111, and each group of first battery pack columns 210 includes 9 battery packs 200 arranged along the height direction of the container 100. In other embodiments, the number of first battery pack columns 210 may be increased or decreased, or the number of battery packs 200 in each group of first battery pack columns 210 may be increased or decreased.
