Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery technology, and in particular to an energy storage container. Background Technology
[0002] In related technologies, energy storage containers typically incorporate a cooling system, which includes a refrigeration unit and a heat exchanger. The refrigerant in the refrigeration unit exchanges heat with the coolant from the cold plates inside the battery pack within the heat exchanger, thereby cooling the battery pack. This cooling system is not only structurally complex and space-consuming, but it is also usually located on the side wall of the energy storage container. When multiple energy storage containers are placed side by side, it can easily create thermal islands. Furthermore, in such energy storage containers, the high-voltage box is usually located below each row of battery packs, resulting in a lack of thermal and electrical separation. This can easily lead to interference between the battery packs and the high-voltage box, affecting the safety and performance of the energy storage container. Utility Model Content
[0003] The purpose of this invention is to provide an energy storage container that not only occupies little space but also enables precise temperature control.
[0004] To achieve the above objectives, the following technical solution is provided:
[0005] Energy storage containers, including:
[0006] The container body, including the mounting cavity;
[0007] A refrigeration mechanism is located on the top of the outer side of the container body; the refrigeration mechanism includes refrigeration components;
[0008] At least one energy storage unit is disposed within the mounting cavity. The energy storage unit includes a high-voltage box and at least one battery pack. In the same energy storage unit, all battery packs are electrically connected to the high-voltage box. The high-voltage boxes of all energy storage units are located at the same end of the mounting cavity, and the battery packs are located on one side of the high-voltage box. The battery pack includes a first cooling element, which is in communication with the cooling element.
[0009] A second cooling component is disposed within the mounting cavity, and the second cooling component is in communication with the refrigeration component.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This utility model discloses an energy storage container with its refrigeration mechanism located at the top of the container body. This not only reduces the footprint of the energy storage container but also avoids the thermal island phenomenon caused by the concentrated placement of refrigeration mechanisms when multiple energy storage containers are placed side by side. By placing the high-voltage boxes of all energy storage units at the same end of the mounting cavity, with the battery pack located on one side of the high-voltage box, mutual interference between the two is avoided, facilitating precise temperature control and improving the safety and performance of the energy storage container. Furthermore, by incorporating a second cooling element within the mounting cavity, the entire cavity can be cooled, further enhancing the cooling effect of the battery pack and meeting the cooling requirements of the high-voltage box, thus promoting precise temperature control.

[0023] like Figures 1 to 2As shown, this embodiment provides an energy storage container, including a container body 1, a refrigeration mechanism 2, an energy storage unit 3, and a second cooling component 4. The container body 1 includes a mounting cavity 11; the refrigeration mechanism 2 is located on the top of the outer side of the container body 1; the refrigeration mechanism 2 includes a refrigeration component; at least one energy storage unit 3 is provided, and the energy storage unit 3 is located within the mounting cavity 11. The energy storage unit 3 includes a high-voltage box 32 and at least one battery pack 31. In the same energy storage unit 3, all battery packs 31 are electrically connected to the high-voltage box 32, and the high-voltage boxes 32 of all energy storage units 3 are located at the same end of the mounting cavity 11, with the battery packs 31 located on one side of the high-voltage box 32; the battery pack 31 includes a first cooling component, which communicates with the refrigeration component; the second cooling component 4 is located within the mounting cavity 11 and communicates with the refrigeration component. It should be noted that the container body 1 is mounted on a mounting base or the ground, and the top of the container body 1 is the side opposite to the mounting base or the ground.
[0024] In this embodiment of the energy storage container, the refrigeration mechanism 2 is located on the top of the outer side of the container body 1. Compared to placing the refrigeration mechanism 2 on the side of the container body 1, there is no need to reserve space for the refrigeration mechanism 2 on the side of the container body 1. This not only helps to reduce the footprint of the energy storage container, but also avoids the thermal island phenomenon caused by the concentrated placement of the refrigeration mechanism 2 when multiple energy storage containers are placed side by side. By placing the battery pack 31 and the high-voltage box 32 on opposite sides of the mounting cavity 11, mutual interference between the two can be avoided, which is conducive to achieving precise temperature control and improving the safety and performance of the energy storage container. At the same time, by providing a second cooling element 4 in the mounting cavity 11, the entire mounting cavity 11 can be cooled through the second cooling element 4. This not only further improves the cooling effect of the battery pack 31, but also meets the cooling requirements of the high-voltage box 32, promoting precise temperature control.
[0025] It should be noted that multiple battery cells (such as multiple battery cells with equal capacity and internal resistance) are connected in series or in parallel to form a battery pack. The battery pack 31 is a complete functional unit that can directly output electrical energy, formed by placing the battery pack, battery management system (BMS), thermal management system, electrical connection system (high-voltage / low-voltage connectors, wiring harnesses, etc.), structural components (casing, brackets, etc.) into the battery box and sealing it.
[0026] Specifically, the first cooling element is configured to cool the individual battery cells in the battery pack. The second cooling element 4 is configured to cool the mounting cavity 11 of the container body 1.
[0027] For example, the first cooling element is a first cold plate; the second cooling element 4 is a second cold plate.
[0028] In some embodiments, the mounting cavity 11 is provided with a column 12 for mounting a battery pack 31 or a high-voltage box 32. Exemplarily, the column 12 has a support portion corresponding to the battery pack 31 or the high-voltage box 32, and the battery pack 31 or the high-voltage box 32 is mounted on the corresponding support portion. Exemplarily, the upper and lower ends of the column 12 are connected to the top and bottom walls of the mounting cavity 11, respectively.
[0029] For example, multiple columns 12 are provided, including a first column 12 for supporting the battery pack 31. Supporting the battery pack 31 with the first column 12 improves the installation stability of the battery pack 31 and prevents it from being excessively compressed, thus improving the safety and performance of the battery pack 31. The multiple columns 12 also include a second column 12 for supporting the high-voltage box 32. Supporting the high-voltage box 32 with the second column 12 improves the installation stability of the high-voltage box 32 and prevents it from being excessively compressed, thus improving the safety and performance of the high-voltage box 32.
[0030] In some embodiments, a portion of the second cooling element 4 is positioned directly opposite the battery pack 31, thereby enabling efficient heat exchange between the second cooling element 4 and the battery pack 31, thus improving the cooling effect on the battery pack 31. Furthermore, another portion of the second cooling element 4 is positioned directly opposite the high-voltage box 32, thereby enabling efficient heat exchange between the second cooling element 4 and the high-voltage box 32, further improving the cooling effect on the high-voltage box 32.
[0031] In some embodiments, at least two energy storage units 3 are provided. Further, at least one refrigeration mechanism 2 is provided. Further, the refrigeration element of each refrigeration mechanism 2 is respectively connected to the first cooling element of at least two energy storage units 3. This arrangement reduces the number of refrigeration mechanisms 2 while meeting the cooling requirements of the energy storage units 3, thereby reducing the space occupied by the energy storage container and lowering costs.
[0032] For example, six energy storage units 3 and three cooling mechanisms 2 are provided. The cooling element of each cooling mechanism 2 is connected to the first cooling element of two energy storage units 3 respectively, thereby improving the cooling effect of the battery pack 31 while also taking into account the space and cost occupied by the energy storage container. Of course, three energy storage units 3 and one cooling mechanism 2 can also be provided, with the cooling mechanism 2 connected to the first cooling element of all three energy storage units 3 simultaneously, thereby also meeting the cooling requirements of the battery pack 31 and further reducing the space and cost occupied by the energy storage container. It should be noted that this embodiment does not limit the number of energy storage units 3 and cooling mechanisms 2.
[0033] In some embodiments, the high-voltage box 32 of all energy storage units 3 is located at one end of the mounting cavity 11 along a first direction; the first direction is the arrangement direction of the multiple energy storage units 3, which on the one hand facilitates the convenience of the layout of the energy storage units 3 in the mounting cavity 11 and facilitates the centralized management of the high-voltage box 32, and on the other hand facilitates the cooling of the high-voltage box 32 by the second cooling component 4, thereby improving the convenience of the assembly and use of the energy storage container.
[0034] In some embodiments, when at least two cooling mechanisms 2 are provided, the at least two cooling mechanisms 2 are arranged at intervals, thereby facilitating rapid heat dissipation of the cooling mechanisms 2.
[0035] In some embodiments, when at least two refrigeration mechanisms 2 are provided, the at least two refrigeration mechanisms 2 are arranged along a first direction. It should be noted that the mounting cavity 11 is maximized along the length of the container body 1, and the arrangement direction of the plurality of energy storage units 3 is the length direction of the container body 1. This allows the container body 1 to accommodate more battery packs 31 and improves the ease of installation of the battery packs 31. By arranging at least two refrigeration mechanisms 2 along the arrangement direction of the plurality of energy storage units 3, the arrangement space for the refrigeration mechanisms 2 can be increased, thereby making the spacing between adjacent refrigeration mechanisms 2 sufficiently large to improve the heat dissipation effect of the refrigeration mechanisms 2.
[0036] Specifically, container body 1 has a cuboid structure, meaning that the length direction, width direction, and height direction of container body 1 are perpendicular to each other, and the height direction of container body 1 is the vertical direction; the length of container body 1 is greater than the width of container body 1.
[0037] In some embodiments, when the energy storage unit 3 includes at least two battery packs 31, all battery packs 31 are connected in series in the same energy storage unit 3 to form a battery cluster. Further, when there are at least two energy storage units 3, the battery clusters of all energy storage units 3 are arranged along a first direction. That is, the battery clusters are arranged in the same way as the cooling mechanism 2, which helps to increase the circulation speed of the refrigerant between the cooling mechanism 2 and the battery packs 31, thereby improving the cooling effect of the battery packs 31 and reducing cold energy loss, thus achieving energy saving and efficiency improvement.
[0038] It should be noted that this embodiment does not limit the arrangement of the battery packs 31 in the same battery cluster. For example, in the same battery cluster, all battery packs 31 can be arranged at intervals in the vertical direction; specifically, as long as there is a certain gap between two adjacent battery packs 31 to avoid the battery packs 31 squeezing each other.
[0039] In some embodiments, the refrigeration mechanism 2 further includes a first blower for blowing air onto the refrigeration component, thereby promoting heat dissipation of the refrigeration component. Furthermore, the first blower is located on top of the refrigeration component, which not only increases the installation space for the first blower, facilitating its assembly and subsequent maintenance, but also prevents the container body 1 from interfering with the first blower, thus improving the heat dissipation efficiency of the refrigeration component.
[0040] In some embodiments, the first air blowing component includes an air inlet and an air outlet; the first air blowing component has an air inlet on at least one side along the second direction; the first direction, the second direction, and the vertical direction are perpendicular to each other. It should be noted that when there are at least two refrigeration mechanisms 2, and the at least two refrigeration mechanisms 2 are arranged along the first direction, that is, the first air blowing components of the at least two refrigeration mechanisms 2 are also arranged along the first direction, by setting the air inlet on one side of the first air blowing component along the second direction, it is possible to avoid the air inlet being blocked by other structures of the energy storage container, which is beneficial to improving the heat dissipation efficiency of the refrigeration components.
[0041] Specifically, the second direction is the width direction of container body 1.
[0042] For example, the first blower has air inlets on both sides along the second direction, which can increase the air intake of the first blower to improve its heat dissipation efficiency for the cooling component. As an alternative, the first blower may also have an air inlet on one side along the second direction.
[0043] In some embodiments, the top of the first air blower is provided with an air outlet, which can prevent the first air blower from blowing directly on the user and can also prevent the air outlet from being blocked by other structures of the energy storage container, thus helping to reduce noise.
[0044] In some embodiments, the energy storage container further includes a second air blower, which is disposed in the mounting cavity 11 and used to blow air onto the second cooling component 4, thereby promoting heat exchange between the second cooling component 4 and the air, battery pack 31 and high-voltage box 32 in the mounting cavity 11, and improving the cooling effect of the energy storage container.
[0045] In some embodiments, the second air blowing component is disposed on the column 12, thereby eliminating the need for a separate installation structure for the second air blowing component, which helps to simplify the structure of the energy storage container and improve the space utilization rate of the energy storage container.
[0046] In some embodiments, the second cooling element 4 is disposed at the bottom of the mounting cavity 11. It should be noted that the bottom of the energy storage container is a weak area for heat dissipation. By disposing of the second cooling element 4 at the bottom of the mounting cavity 11, the heat dissipation effect of the weak area of the energy storage container can be improved, thereby improving the temperature control accuracy of the energy storage container.
[0047] In some embodiments, the refrigeration mechanism 2 further includes an output pipe 21, one end of which is connected to the refrigeration component and the other end is connected to the first cooling component and the second cooling component 4, thereby delivering the refrigerant of the refrigeration component to the first cooling component and the second cooling component 4 through the output pipe 21.
[0048] Furthermore, a first pipeline limiting component is provided inside the installation cavity 11, and the output pipeline 21 is connected to the first pipeline limiting component. The output pipeline 21 is then fixed by the first pipeline limiting component, which improves the stability of the installation of the output pipeline 21 and avoids problems such as leakage.
[0049] In some embodiments, the output pipe 21 is snapped into place with the first pipe limiting member, thereby facilitating quick assembly and disassembly of the output pipe 21 and improving the convenience of assembly and subsequent maintenance of the output pipe 21. For example, the first pipe limiting member is a pipe clip.
[0050] In some embodiments, the first pipeline limiting member is provided on the column 12, thereby eliminating the need for a separate installation structure for the first pipeline limiting member, which helps to simplify the structure of the energy storage container and improve the space utilization rate of the energy storage container.
[0051] In some embodiments, the refrigeration mechanism 2 further includes a return pipe 22, one end of which is connected to the refrigeration component and the other end is connected to the first cooling component and the second cooling component 4, thereby sending the refrigerant in the first cooling component and the second cooling component 4 back to the refrigeration component through the return pipe 22 to realize refrigerant circulation.
[0052] Furthermore, a second pipeline limiting component is provided inside the installation cavity 11. The return pipeline 22 is connected to the second pipeline limiting component, thereby fixing the return pipeline 22 through the second pipeline limiting component, improving the stability of the installation of the return pipeline 22, and avoiding problems such as leakage.
[0053] In some embodiments, the return pipe 22 is snapped into place with the second pipe limiting member, thereby facilitating quick assembly and disassembly of the return pipe 22 and improving the convenience of assembly and subsequent maintenance of the return pipe 22. For example, the second pipe limiting member is a pipe clip.
[0054] In some embodiments, the second pipeline limiting member is provided on the column 12, thereby eliminating the need for a separate installation structure for the second pipeline limiting member, which helps to simplify the structure of the energy storage container and improve the space utilization rate of the energy storage container.
[0055] In some embodiments, the flow area of the output pipe 21 is a (mm²). 2 The flow area of the return pipe 22 is b (mm²). 2The refrigerant circulation speed can be controlled more precisely by limiting the refrigerant circulation speed to 0.53 ≤ a / b ≤ 0.66, thereby improving the temperature control accuracy of the energy storage container.
[0056] For example, the value of a / b can be any value between 0.53 and 0.66, such as a / b can be 0.53, 0.55, 0.6 or 0.66, etc.
[0057] In some embodiments, 42.9 (mm) 2 )≤a (mm) 2 ≤171.9 (mm) 2 By limiting it to 42.9 (mm) 2 )≤a (mm) 2 ≤171.9 (mm) 2 This allows the output pipe 21 to provide sufficient refrigerant, thereby improving the cooling effect of the energy storage container.
[0058] For example, a(mm) 2 The value can be 42.9 (mm) 2 ) to 171.9 (mm) 2 Any value between ) and , for example, a(mm 2 The value can be 42.9 (mm) 2 ), 50 (mm) 2 ), 100 (mm) 2 ), 150 (mm) 2 ) or 171.9 (mm) 2 )wait.
[0059] In some embodiments, 80.8 (mm) 2 )≤b (mm) 2 ≤188 (mm) 2 By limiting it to 80.8 (mm) 2 )≤b (mm) 2 ≤188 (mm) 2 This allows the refrigerant to quickly return through the return pipe 22, thereby increasing the refrigerant circulation speed and improving the cooling effect of the energy storage container.
[0060] For example, b (mm) 2 It can be 80.8 (mm) 2 ) to 188 (mm) 2 Any value between ), for example, b (mm) 2 It can be 80.8 (mm) 2 ), 100 (mm) 2 ), 150 (mm) 2 ) or 188 (mm)2 )wait.
[0061] It should be noted that when the output pipe 21 includes at least two output pipes, the flow area of the output pipe 21 is the sum of the flow areas of all output pipes. When the return pipe 22 includes at least two return pipes, the flow area of the return pipe 22 is the sum of the flow areas of all return pipes.
[0062] In some embodiments, the refrigeration mechanism 2 further includes an output pipe 21 and a first connecting branch pipe corresponding to each battery pack 31. The output pipe 21 is connected to the refrigeration component, one end of the first connecting branch pipe is connected to the output pipe 21, and the other end is connected to the first cooling component of the corresponding battery pack 31. This allows the refrigerant output by the refrigeration component to be delivered evenly and quickly to the first cooling component of each battery pack 31, thereby improving the cooling effect of the battery pack 31.
[0063] In some embodiments, the refrigeration mechanism 2 further includes a return pipe 22 and a second connecting branch pipe corresponding to the battery pack 31. The return pipe 22 is connected to the refrigeration component, one end of the second connecting branch pipe is connected to the return pipe 22, and the other end is connected to the first cooling component of the corresponding battery pack 31. This allows the refrigerant in the first cooling component of each battery pack 31 to flow back to the refrigeration component quickly, and improves the convenience of connecting the return pipe 22 to the first cooling component.
[0064] For example, when there are at least two refrigeration mechanisms 2, the output pipes 21 of all refrigeration mechanisms 2 are connected to the second cooling element 4, for example, through a multi-port connector. This allows at least two refrigeration mechanisms 2 to supply refrigerant to the second cooling element 4, which improves the cooling effect of the second cooling element 4. Alternatively, the second cooling element 4 can be configured in a one-to-one correspondence with each refrigeration mechanism 2, allowing the output pipes 21 of the refrigeration mechanism 2 to connect to the corresponding second cooling element 4, thus improving assembly convenience. It should be noted that the connection method between the return pipe 22 of the refrigeration mechanism 2 and the second cooling element 4 can refer to the connection method between the output pipe 21 of the refrigeration mechanism 2 and the second cooling element 4 described above, and will not be repeated here.
[0065] For example, the refrigeration unit 2 is also provided with a circulation pump, which is located in the output line 21, thereby promoting refrigerant circulation.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention.
