[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0024] Figure 1 A partial schematic diagram of the first type of energy storage container is shown.

[0025] like Figure 1 The energy storage container includes a container body 100, the interior of which can be divided into multiple spaces, with larger spaces used to accommodate multiple battery clusters 200 (also referred to as "battery packs"). Each battery cluster 200 may include a mounting bracket fixed to the container body 100, the mounting bracket being configured along the height direction of the container body 100 (e.g., ...). Figure 1The enclosure 100 has multiple mounting positions arranged in the Z direction. The bottom mounting position is used to install the high-voltage box 220, while the other mounting positions can be used to install the battery pack 210. The battery pack 210 is electrically connected to the high-voltage box 220 via a cable extending along the height direction of the enclosure 100, i.e., vertical wiring. A current combiner 400 can be installed in another space inside the enclosure 100, and all the high-voltage boxes 220 in the multiple battery clusters 200 are electrically connected to the current combiner 400.

[0026] Combination Figure 1 It can be seen that since the high voltage box 220 is integrated in the battery cluster 200, the high voltage box 220 and the battery pack 210 are placed in the same space. As for other spaces (for example, the space where the combiner device 400 is placed), although there is some spare space inside, it is not enough to accommodate a complete battery cluster 200. Furthermore, the lateral space occupied by the high voltage box 220 is less than that of the battery pack 210. This results in the waste of this space, leading to a lower energy density of the energy storage container.

[0027] To address the aforementioned issues, this application provides alternative energy storage container structures.

[0028] Figure 2 A partial schematic diagram of the second type of energy storage container is shown.

[0029] like Figure 2 In some embodiments, the energy storage container includes: a container body 100, the internal space of which is divided to form an energy storage compartment 110 and a functional compartment 120; multiple battery clusters 200 disposed within the energy storage compartment 110, each battery cluster 200 including multiple battery packs 210; a high-voltage device 300 disposed within the functional compartment 120, the high-voltage device 300 including multiple high-voltage units 310, each high-voltage unit 310 being electrically connected to a corresponding battery pack 210; and a combiner device 400 disposed within the functional compartment 120 and adjacent to the high-voltage device 300; the combiner device 400 being electrically connected to the multiple high-voltage units 310 respectively.

[0030] For example, vertical partitions can be installed in the interior space of the container 100 to divide the interior space of the container 100 into energy storage compartment 110, functional compartment 120 or other compartments.

[0031] For example, each high-voltage unit 310 may be provided with a separate outer shell to form a box structure, and the number of box structures provided in the functional compartment 120 is equal to the number of high-voltage units 310; or, multiple high-voltage units 310 may be provided with a single outer shell to form a box structure, and the number of box structures provided in the functional compartment 120 is less than the number of high-voltage units 310.

[0032] For example, each high-voltage unit 310 may be electrically connected to multiple battery packs 210 connected in series.

[0033] For example, multiple battery packs 210 can be electrically connected to each other, to the battery pack 210 and the high voltage unit 310, and to the high voltage unit 310 and the combiner 400 via electrical connection lines (e.g., cables).

[0034] Compared to the first type of energy storage container, in the second type, the high-voltage unit 310 of each battery cluster 200 is removed from the energy storage compartment 110 and integrated into a high-voltage device 300, which is then placed uniformly in the functional compartment 120. This effectively utilizes the relatively small space within the functional compartment 120 (insufficient space to accommodate the entire battery cluster 200). The space originally used for installing the high-voltage unit 310 in the energy storage compartment 110 can be used to install additional battery packs 210, thereby increasing the total number of battery packs 210 installed in the energy storage compartment 110 and improving the energy density of the energy storage container. Simultaneously, the combiner device 400 located in the functional compartment 120 is positioned adjacent to the high-voltage device 300, facilitating electrical connection between the combiner device 400 and the multiple high-voltage units 310 within the high-voltage device 300.

[0035] The energy storage container provided in this embodiment places the battery pack 210 inside the energy storage compartment 110, and integrates the high-voltage unit 310, which is electrically connected to the battery pack 210, into a high-voltage device 300 and places it in the functional compartment 120. In this way, on the one hand, the space utilization rate of the functional compartment 120 is improved, and on the other hand, more battery packs 210 can be placed in the energy storage compartment 110. Compared with placing both the high-voltage unit 310 and the battery pack 210 inside the energy storage compartment 110, the energy density of the energy storage container can be increased by at least 12.5%.

[0036] Figure 3 This diagram shows a partial side view of the first type of energy storage container with the second structure. Figure 4 A partial schematic diagram of the second side view of the second type of energy storage container structure is shown.

[0037] like Figure 3 and Figure 4 In some embodiments, each high-voltage unit 310 includes a high-voltage input terminal 311 and a high-voltage output terminal 312, the battery pack 210 includes a battery output terminal 211, and the combiner device 400 includes a combiner input terminal 410; the high-voltage input terminal 311 and the battery output terminal 211 are located on the same side of the housing 100 and are electrically connected to each other; the high-voltage output terminal 312 and the combiner input terminal 410 are located on the same side of the housing 100 and are electrically connected to each other.

[0038] For example, the high-voltage input terminal 311 and the high-voltage output terminal 312 can be respectively located on opposite sides or adjacent sides of the high-voltage unit 310.

[0039] For example, when the housing 100 has a cuboid structure, the battery output terminal 211 and the high-voltage input terminal 311 are located on the side of the housing 100 with a larger area, such as... Figure 3 The bus input terminal 410 and the high voltage output terminal 312 are located on the smaller side of the enclosure 100, such as... Figure 4 .

[0040] Since the battery output terminal 211 and the high voltage input terminal 311 need to be electrically connected, when the two are connected by an electrical connection line, if they are located on the same side of the container 100, then the distance between them is relatively small. The electrical connection line does not need to be reversed around the circumference of the container 100. This can reduce the length of the electrical connection line, thereby reducing material costs, and also reduce the difficulty of wiring, making the wiring inside the energy storage container simpler and more aesthetically pleasing.

[0041] The beneficial effects of having the bus input terminal 410 and the high voltage output terminal 312 located on the same side of the housing 100 are similar to those of having the battery output terminal 211 and the high voltage input terminal 311 located on the same side of the housing 100, and will not be repeated here.

[0042] like Figure 2 , Figure 3 and Figure 4 In some embodiments, the energy storage compartment 110 and the functional compartment 120 are aligned along a first direction (e.g., Figure 2 The functional compartments 120 are arranged adjacent to each other in the X direction, and the energy storage compartments 110 are located at the ends of the housing 100; the energy storage compartments 110 include those along the second direction (such as the X direction). Figure 2 The energy storage opening 111 is provided in the Y direction; the functional compartment 120 includes a first functional opening 121 provided in the second direction and a second functional opening 122 provided in the first direction; the first direction, the second direction and the height direction of the housing 100 (e.g., the first direction, the second direction and the height direction of the housing 100) are provided in the Y direction. Figure 2 The Z-direction of the batteries are perpendicular to each other; the battery output terminal 211 faces the energy storage opening 111, the high voltage input terminal 311 faces the first functional opening 121, and the high voltage output terminal 312 and the bus input terminal 410 both face the second functional opening 122.

[0043] For example, in this embodiment, the first direction is the length direction of the box 100, and the second direction is the width direction of the box 100.

[0044] It should be noted that the battery output terminals 211 of all battery packs 210 inside the energy storage container can be exposed through the energy storage opening 111, the high voltage input terminals 311 of all high voltage units 310 can be exposed through the first functional opening 121, and the high voltage output terminals 312 of all high voltage units 310 and all bus input terminals 410 can be exposed through the second functional opening 122.

[0045] In this embodiment, the battery output terminal 211 and the current input terminal 410 are located on adjacent, mutually perpendicular sides of the housing 100. More battery packs 210 can be arrayed on the same side of the housing 100 (along the first direction and the height direction of the housing 100) without having to leave space on that side for setting the current input terminal 410, which helps to further improve the energy density of the energy storage container.

[0046] In the energy storage container of this embodiment, the operator can fix the battery pack 210, high-voltage unit 310, and combiner device 400 in preset positions inside the energy storage container. Then, an electrical connection cable is connected to the battery output terminal 211 through the energy storage opening 111, to the high-voltage input terminal 311 through the first functional opening 121, and to the high-voltage output terminal 312 and combiner input terminal 410 through the second functional opening 122. This not only makes wiring and subsequent maintenance more convenient, but also reduces the redundancy of electrical connection cables, lowers the material cost of electrical connection cables, and makes the wiring inside the energy storage container simpler and more aesthetically pleasing.

[0047] like Figure 2 , Figure 3 and Figure 4 In some embodiments, multiple battery clusters 200 are arranged along a first direction, multiple high-voltage units 310 are arranged along the height direction of the housing 100, and a combiner device 400 is disposed along a second direction on the side of the high-voltage device 300 away from the first functional opening 121.

[0048] For example, each battery cluster 200 includes a plurality of battery packs 210 arranged along the height direction of the housing 100.

[0049] It should be noted that, in this embodiment, each battery cluster 200 may be provided with a mounting bracket, and the mounting bracket may have a single row of multi-layer mounting positions. Correspondingly, multiple mounting brackets arranged along the first direction are installed in the energy storage compartment 110, and the battery packs 210 included in each battery cluster 200 are all installed on the corresponding mounting bracket. Alternatively, a mounting bracket may be provided in the energy storage compartment 110, and the mounting bracket may have multiple rows of multi-layer mounting positions, and the battery packs 210 included in multiple battery clusters 200 may be installed on the same mounting bracket.

[0050] Multiple high-voltage units 310 are arranged along the height direction of the enclosure 100, so that the high-voltage output terminals 312 of the multiple high-voltage units 310 are roughly located in the same vertical plane, and the high-voltage input terminals 311 of the multiple high-voltage units 310 are also roughly located in the same vertical plane. Compared with the horizontal arrangement of multiple high-voltage units 310, this helps to save installation and wiring space.

[0051] Meanwhile, in this embodiment, the combiner device 400 is placed on the side of the high-voltage device 300 away from the first functional opening 121, which can prevent the combiner device 400 from blocking the high-voltage input terminal 311 and facilitate the electrical connection between the high-voltage unit 310 and the battery pack 210.

[0052] Figure 5 A partial schematic diagram of the high-voltage unit 300 and the combiner unit 400 in the second type of energy storage container is shown. Figure 6 A partial side view of the high-voltage device 300 of the second type of energy storage container is shown. Figure 7 A partial side view of the second type of energy storage container structure is shown, illustrating the high-voltage unit 300 and the combiner unit 400.

[0053] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the high-voltage device 300 further includes a high-voltage storage cabinet 320. Each high-voltage unit 310 includes a high-voltage housing 313. The internal space of the high-voltage storage cabinet 320 is at least used to accommodate the high-voltage housing 313. The high-voltage storage cabinet 320 includes a first cabinet opening 321 facing the second functional opening 122 and a second cabinet opening 322 facing the first functional opening 121. The high-voltage housing 313 moves into or out of the high-voltage storage cabinet 320 through the first cabinet opening 321. The high-voltage output terminal 312 is exposed through the first cabinet opening 321, and the high-voltage input terminal 311 is exposed through the second cabinet opening 322.

[0054] For example, the device serving as the high-voltage input terminal 311 and the device serving as the high-voltage output terminal 312 can both be disposed in the high-voltage housing 313, and partially exposed for connection with electrical connection lines.

[0055] The high-voltage storage cabinet 320 can be fixed in a preset position in the functional compartment 120. The high-voltage box 313 can be moved into the high-voltage storage cabinet 320 through the first cabinet opening 321 and fixed in a preset position inside the high-voltage storage cabinet 320, thus achieving an arrangement along the height direction of the container 100. Multiple high-voltage units 310 in the energy storage container can be integrated into the high-voltage storage cabinet 320. The high-voltage input terminal 311 of the high-voltage unit 310 located in the high-voltage storage cabinet 320 can be exposed through the second cabinet opening 322 to facilitate electrical connection with the battery output terminal 211, and the high-voltage output terminal 312 can be exposed through the first cabinet opening 321 to facilitate electrical connection with the combiner input terminal 410.

[0056] When maintenance is required on the high-voltage unit 310, the corresponding high-voltage box 313 can be moved out of the high-voltage storage cabinet 320 through the first cabinet opening 321 for maintenance.

[0057] like Figure 5 In some embodiments, the internal space of the high-voltage storage cabinet 320 is divided into multiple storage compartments 323 corresponding one-to-one with the high-voltage box 313, and each storage compartment 323 is connected to the first cabinet opening 321 and the second cabinet opening 322.

[0058] In this embodiment, the high-voltage box 313 of each high-voltage unit 310 can be set up separately in their respective corresponding housing compartments 323. When it is necessary to maintain one of the high-voltage units 310, the high-voltage box 313 of that high-voltage unit 310 can be taken out separately through the first cabinet opening 321, while the other high-voltage boxes 313 can remain unaffected in their respective corresponding housing compartments 323.

[0059] In this embodiment, the high-voltage boxes 313 of multiple high-voltage units 310 and the high-voltage storage cabinet 320 are constructed into a drawer cabinet structure, which allows any high-voltage box 313 to be individually pulled out and put in, which helps to reduce the maintenance difficulty of the high-voltage units 310 and facilitates maintenance operations.

[0060] Figure 4a Showing Figure 4 An enlarged schematic diagram of part A in the middle.

[0061] like Figure 3 , Figure 4 and Figure 4a In some embodiments, the high-voltage housing 313 has a wiring space 600 on the side near the first functional opening 121, the wiring space 600 being used to accommodate at least a portion of the electrical connection wires connected to the high-voltage input terminal 311.

[0062] For example, the dimension of the routing space 600 along the second direction is L1, and L1 is not less than 40mm.

[0063] For example, a through hole may be provided on the partition between the energy storage compartment 110 and the functional compartment 120, and the electrical connection wire connected to the battery output terminal 211 can pass through the through hole through the partition and be connected to the high voltage input terminal 311.

[0064] In the wiring space 600, the electrical connection wire can be extended according to the wiring requirements and electrically connected to the high voltage input terminal 311, so that the operator can easily make an electrical connection between the battery output terminal 211 and the high voltage input terminal 311 through the electrical connection wire.

[0065] like Figure 5 In some embodiments, the top of the high-voltage housing 313 is provided with a top opening 3131, and the interior of the high-voltage housing 313 is connected to the outside through the top opening 3131.

[0066] For example, the top opening 3131 can cover the top of the high voltage box 313, that is, the high voltage box 313 is a structure with an open top.

[0067] The top of the high voltage box 313 is provided with a top opening 3131, which allows the components inside the high voltage box 313 to be exposed through the top opening 3131. This facilitates maintenance of the components inside the high voltage box 313 by operators and also helps the components inside the high voltage box 313 to exchange heat with the outside environment, thus improving heat dissipation efficiency. The partition that divides the internal space of the high voltage storage cabinet 320 into multiple compartments 323 is suitable for shielding and protecting the top opening 3131, thus serving as a temporary cover for the high voltage box 313.

[0068] like Figure 2 In some embodiments, a temperature control unit 500 is also provided in the functional compartment 120. The temperature control unit 500 is used to regulate the temperature in the functional compartment 120 and the energy storage compartment 110. The temperature control unit 500 is located above the high-voltage device 300.

[0069] For example, the temperature control unit 500 can be an air conditioner or a liquid chiller.

[0070] For example, a power distribution device is also provided in the functional compartment 120.

[0071] For example, the temperature control unit 500 may also have space for wiring on the side near the first functional opening 121.

[0072] The temperature control unit 500, high voltage device 300 and junction device 400 are all located in the functional compartment 120. On the one hand, this can improve the space utilization rate of the functional compartment 120. On the other hand, when dividing the space inside the container 100, the energy storage compartment 110 can have more space to accommodate more battery packs 210 and improve the energy density of the energy storage container.

[0073] Meanwhile, the temperature control unit 500 can also achieve relatively efficient heat exchange with the high-voltage unit 310 and the busbar device 400 in the high-voltage device 300 below it, so that the temperature of the high-voltage unit 310 can be controlled at a suitable operating temperature, so as to ensure that the high-voltage unit 310 can operate relatively stably and safely.

[0074] In conjunction with the foregoing, the top of the high-pressure housing 313 is provided with a top opening 3131, which allows the temperature control unit 500 located above the high-pressure housing 313 to exchange heat with the high-pressure housing 313 more efficiently.

[0075] like Figure 3 In some embodiments, multiple battery clusters 200 are arranged along a first direction, and each battery cluster 200 includes multiple battery packs 210 arranged along the height direction of the housing 100; the first direction is perpendicular to the height direction of the housing 100; the multiple battery packs 210 arranged in the same layer are connected in series with each other and electrically connected to the corresponding high-voltage unit 310.

[0076] For example, along the height direction of the housing 100, the energy storage compartment 110 is provided with six to twelve layers of battery packs 210.

[0077] by Figure 3 Taking the structure and orientation shown as an example, the energy storage compartment 110 can be equipped with four battery clusters 200, arranged along the first direction. Each battery cluster 200 includes nine battery packs 210 arranged in a single row. In other words, the energy storage compartment 110 has a total of four columns and nine layers (or nine rows) of battery packs 210. In order to meet the total rated voltage requirements of the circuit (for example, if the total rated voltage of the circuit is required to be 1330V, the rated voltage of each battery pack 210 is close to 333V), the four battery packs 210 in the same layer can be connected in series, and the electrical connection wires can be extended to the right edge of the energy storage compartment 110 in a horizontal routing manner, and then enter the functional compartment 120 to be electrically connected to the corresponding high-voltage unit 310.

[0078] Figure 8 A schematic diagram showing another wiring method for the second type of energy storage container is presented.

[0079] like Figure 8 In some embodiments, multiple battery packs 210 on two adjacent layers are connected in series and electrically connected to the corresponding high-voltage unit 310.

[0080] by Figure 8Taking the structure and orientation shown as an example, the energy storage compartment 110 can be equipped with four battery clusters 200, arranged along the first direction. Each battery cluster 200 includes nine battery packs 210 arranged in a single row. In other words, the energy storage compartment 110 has a total of four columns and nine layers (or nine rows) of battery packs 210. In order to meet the total rated voltage requirements of the circuit (for example, if the total rated voltage of the circuit is required to be 1330V, the rated voltage of each battery pack 210 is close to 167V), eight battery packs 210 in two adjacent layers can be connected in series, and the electrical connection wires can be extended to the right edge of the energy storage compartment 110 in a horizontal routing manner, and then enter the functional compartment 120 to be electrically connected to the corresponding high-voltage unit 310.

[0081] It should be noted that, in this embodiment, the positive and negative terminals of adjacent battery packs are in opposite positions. For example, the left side of the top-layer battery pack is the positive terminal and the right side is the negative terminal, while the left side of the second-to-top-layer battery pack is the negative terminal and the right side is the positive terminal.
