Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to an energy storage container. Background Technology

[0002] Energy storage containers are modular power devices that integrate electrochemical energy storage units within standardized containers. They feature high power density, rapid deployment, and flexible expansion, and are widely used in fields such as power security and emergency power supply.

[0003] Currently, battery packs in energy storage containers are generally cooled by cooling air. However, when there are a large number of battery packs, it is not possible to cool each battery pack evenly with the cooling air, resulting in poor heat dissipation for some battery packs and localized overcooling in others.

[0006] In some embodiments, the second wind deflector is located above the battery module, and the height of the second wind deflector is less than the height of the first wind deflector, so that some cooling air flows from above or below the second wind deflector to the second air intake space.

[0007] In some embodiments, the height of the first wind deflector is H1, the height of the second wind deflector is H2, and H2 / H1 = 0.5 to 0.7.

[0009] In some embodiments, the first air inlet is configured to face the first end face; there is a second gap between the battery module and the first end face; the energy storage container further includes: a third baffle plate, which is disposed at the first air inlet and partially overlaps with the first air inlet; there is a gap between the third baffle plate and the first air inlet, and the gap communicates with the second gap; a portion of the cooling air entering from the first air inlet is blocked by the third baffle plate and flows downward into the second gap.

[0010] In some embodiments, the bottom of the third wind deflector is connected to the top of the battery module; the top of the third wind deflector is connected to the top surface, or the top of the third wind deflector is connected to the top of the first wind deflector.

[0011] In some embodiments, the first air inlet includes two first sub-air inlets arranged side by side, the third baffle is located between the two first sub-air inlets, and the third baffle partially overlaps with the two first sub-air inlets.

[0012] In some embodiments, the third baffle plate provides the same degree of obstruction to the two first sub-air inlets.

[0013] In some embodiments, the first baffle includes: an end plate disposed along the top edge of the first end face, and the first air inlet disposed on the end plate; a first side plate disposed along the upper edge of the first side face, one end of the first side plate being connected to the end plate and the other end being connected to the second end face; a second side plate disposed along the upper edge of the second side face, one end of the second side plate being connected to the end plate and the other end being connected to the second end face; the first side plate has a second air inlet for allowing cooling air to enter, and the second side plate has a third air inlet for allowing cooling air to enter.

[0014] In some embodiments, the tops of the end plate, the first side plate, and the second side plate are all connected to the top surface; the bottoms of the first side plate and the second side plate are all connected to the top of the battery module; there is a second gap between the battery module and the first end surface, and the end plate is located above the second gap in the first axial direction.

[0015] In some embodiments, one end of the second wind deflector is fixedly connected to the first side plate, and the other end is fixedly connected to the second side plate; the bottom of the second wind deflector is connected to the top of the battery module, or the top of the second wind deflector is connected to the top surface; both ends of the second wind deflector have notches for wires to pass through.

[0016] In some embodiments, the battery module includes a first battery sub-module and a second battery sub-module arranged sequentially along the cooling airflow direction of the first air inlet; the second air inlet faces the second battery sub-module, and the third air inlet faces the first battery sub-module.

[0017] In some embodiments, the system further includes an end cooling module disposed on the first end face, a first side cooling module disposed on the first side face, and a second side cooling module disposed on the second side face; the cooling air outlet of the end cooling module is connected to the first air inlet; the cooling air outlet of the first side cooling module is connected to the second air inlet; and the cooling air outlet of the second side cooling module is connected to the third air inlet.

[0018] In some embodiments, the first battery submodule and the second battery submodule are staggered along the first axial direction to form a space between the first battery submodule and the second side to accommodate the second side cooling module, and a space between the second battery submodule and the first side to accommodate the first side cooling module.

[0019] In some embodiments, the container further includes a second space, the first space and the second space are arranged sequentially along the first axis, and the second end face separates the first space and the second space from each other; the energy storage container further includes an electrical module disposed in the second space for controlling the charging and discharging of the battery module; the container also has a bottom surface; the bottom surface is located below the first space and the second space for supporting the first space and its components, and supporting the second space and its components.

[0020] By applying the above technical solution, a first baffle is set between the top of the battery module and the top surface of the first space, so that the first baffle, the top surface and the second end face form an air intake space covering the top of the battery module. A second baffle is set in the air intake space, which divides the air intake space into a first air intake space close to the first air intake and a second air intake space away from the first air intake. The second baffle can partially block the cooling air flowing from the first air intake space to the second air intake space, thereby blocking the downstream flow from the first air intake. This allows some cooling air to remain in the first air intake space, while the other part of the cooling air enters the second air intake space smoothly through the second baffle. This guides and distributes the cooling air entering the cooling space, making the distribution of cooling air in the air intake space more uniform, achieving uniform cooling of the entire battery module, and thus improving the heat dissipation effect of the entire battery module.

[0021] In addition, a third baffle is installed at the first air inlet, which partially overlaps with the first air inlet. Because there is a gap between the third baffle and the first air inlet that connects to the second gap, some of the cooling air blocked by the third baffle can enter the second gap through this gap and further enter the battery module under the action of the battery module's exhaust fan, thereby cooling the battery pack in the second gap and improving the overall heat dissipation efficiency of the battery pack.

[0040] An energy storage container according to an embodiment of this application provides an air intake space that covers the top of the battery module by setting a first baffle between the top of the battery module and the top surface of a first space. The first baffle, the top surface, and the second end face form an air intake space covering the top of the battery module. A second baffle is set in the air intake space to divide the air intake space into a first air intake space near the first air intake and a second air intake space away from the first air intake. The second baffle can partially block the cooling air flowing from the first air intake space to the second air intake space, thereby guiding and distributing the cooling air entering the cooling space. This allows a portion of the cooling air to remain in the first air intake space to cool that part of the battery module, while another portion of the cooling air passes through the second baffle and enters the second air intake space to cool that part of the battery module. This makes the distribution of cooling air in the air intake space more uniform, thereby improving the heat dissipation effect on the battery module.

[0041] It should be noted that the wind deflector described in this application is a device for blocking or guiding airflow. It is merely an exemplary illustration and does not explicitly limit its shape. Any component that can achieve the function of the wind deflector in this application should be considered to fall within the protection scope of this application.

[0042] like Figure 1 and Figure 2 As shown, the energy storage container includes:

[0043] The enclosure 100 has a first space 110. The first space 110 has a first end face 1001, a second end face 1002, a first side face 1003, and a second side face 1004 in its circumferential direction. The top of the first space 110 has a top surface. The first end face 1001 and the second end face 1002 are arranged opposite to each other, and the direction from the first end face 1001 to the second end face 1002 is the first axis. The first side face 1003 and the second side face 1004 are arranged opposite to each other, and the direction from the first side face 1003 to the second side face 1004 is the second axis. The first axis and the second axis are perpendicular to each other.

[0044] Battery module 111 is disposed within the first space 110;

[0045] The first baffle plate 112 is disposed between the top of the battery module 111 and the top surface of the first space 110. The first baffle plate 112 is disposed along the upper edge of the first end face 1001, the upper edge of the first side face 1003 and the upper edge of the second side face 1004. The first baffle plate 112, the top surface and the second end face 1002 form an air intake space covering the top of the battery module 111. The first baffle plate 112 is provided with a first air inlet 11210 for cooling air to enter the air intake space. The first air inlet 11210 is disposed opposite to the first end face 1001.

[0046] A second baffle plate 113 is disposed within the air intake space and opposite to the first air intake 11210. The second baffle plate 113 divides the air intake space into a first air intake space near the first air intake 11210 and a second air intake space away from the first air intake 11210. The second baffle plate 113 partially blocks the cooling air flowing from the first air intake space to the second air intake space. This partial blocking can be achieved by setting the height of the second baffle plate 113 or by opening holes in the second baffle plate 113.

[0047] Without the second baffle 113, the cooling air entering the air intake space from the first air inlet 11210 will flow directly towards the vicinity of the second end face 1002 without obstruction. This cooling air will then sink further into the battery modules near the second end face 1002 under the influence of gravity and the exhaust fan within the battery modules. Meanwhile, the battery modules further away from the second end face 1002 will not receive sufficient cooling air due to the limited suction of the exhaust fan. This results in the battery modules near the second end face 1002 being overcooled, while the battery modules further away from the second end face 1002 experience poor heat dissipation and localized overheating.

[0048] In this embodiment, the energy storage container includes a container body 100, within which a first space 110 is provided. The shape of the projection of the first space 110 onto a plane can be rectangular or square, depending on the size and number of battery modules 111. Battery modules 111 are disposed within the first space 110, and each battery module 111 may include multiple battery packs for storing electrical energy and providing external power. During operation, the battery modules 111 generate heat. To maintain a reasonable operating temperature, cooling air is introduced to the top of the battery modules 111. This cooling air, under gravity, sinks into the gaps between the battery packs, thus cooling the battery modules 111.

[0049] The top surface of the first baffle plate 112 and the second end face 1002 of the first space 110 form an air intake space covering the top of the battery module 111. Cooling air from air conditioning or other refrigeration equipment can enter the air intake space through the first air inlet 11210 on the first baffle plate 112, thus covering the entire battery module with cooling air. The second baffle plate 113 divides the air intake space into a first air intake space near the first air inlet 11210 and a second air intake space away from the first air inlet 11210. There are gaps between the battery packs. After the cooling air enters the first air intake space through the air inlet of the first baffle plate 112, a portion of the cooling air is blocked by the second baffle plate 113 and remains in the first air intake space and sinks through the corresponding gaps to cool the battery packs in the battery module 111 corresponding to the first air intake space. Due to the partial obstruction by the second baffle 113, another portion of the cooling air flows smoothly from the first air intake space through the second baffle 113 into the second air intake space. After descending through the corresponding gap in the second air intake space, it cools the battery pack in the battery module 111 corresponding to the second air intake space. Optionally, the shape and size of the first and second air intake spaces can be the same or different, depending on the flow rate and velocity of the cooling air and the distribution of the battery packs in the battery module 111. In some embodiments of this application, each battery pack is equipped with an exhaust fan. The cooling air from the air intake space enters the battery module 111 for cooling under the action of gravity and the exhaust fan, thereby improving heat dissipation efficiency.

[0050] The energy storage container of this application embodiment includes a container body 100, a battery module 111, a first wind deflector 112, and a second wind deflector 113. By setting the first wind deflector 112 between the top of the battery module 111 and the top surface of the first space 110, the first wind deflector 112, its top surface, and the second end face 1002 form an air intake space covering the top of the battery module 111. The second wind deflector 113 is set within the air intake space, dividing the air intake space into a first air intake space near the first air inlet 11210 and a second air intake space away from the first air inlet 11210. In this process, the second baffle 113 can partially block the cooling air flowing from the first air intake space to the second air intake space, thereby blocking the downstream flow from the first air intake 11210. This causes part of the cooling air to remain in the first air intake space, while the other part smoothly enters the second air intake space through the second baffle 113. This guides and distributes the cooling air entering the cooling space, making the distribution of cooling air in the air intake space more uniform, so as to achieve uniform cooling of the entire battery module 111. This improves the heat dissipation effect of the battery module 111 and effectively prevents the battery module from being overheated or undercooled in some areas.

[0051] In some embodiments of this application, such as Figure 1 and Figure 3As shown, the second wind deflector 113 is located above the battery module 111, and the height of the second wind deflector 113 is less than the height of the first wind deflector 112.

[0052] In this embodiment, since the second baffle plate 113 is located above the battery module 111 and its height is less than that of the first baffle plate 112, there is a certain gap between the second baffle plate 113 and the top surface of the first space 110. The cooling air entering the first space 110 from the first air inlet 11210 can smoothly enter the second air inlet space through this gap, so that the second baffle plate 113 can block the flow from the first air inlet 11210, making the cooling air more evenly distributed in the first space 110.

[0053] In some embodiments of this application, a gap for cooling air to pass through may also be formed between the bottom of the second baffle 113 and the top of the battery module 111.

[0054] In some embodiments of this application, such as Figure 10 As shown, the height of the first wind deflector 112 is H1 (i.e., the distance between the top of the battery module and the top surface of the first space 110 is also H1), the height of the second wind deflector 113 is H2, and the height of the third wind deflector 114 is H3. Preferably, H2 / H1 = 0.5 to 0.7, and more preferably, H2 / H1 = 0.6. Additionally, from... Figure 10 As can be seen from the above, the height H2 of the second baffle plate 113 can be lower than the height of the first sub-air inlet 11211, and the height H3 of the third baffle plate 114 can be higher than the height of the first sub-air inlet 11211.

[0055] In some embodiments of this application, in addition to making the height of the second baffle 113 less than the height of the first baffle 112, one or more ventilation holes can be made on the second baffle 113 so that cooling air can enter the second air intake space from the upper part of the first baffle 112 and the ventilation holes, thereby guiding the cooling air more efficiently.

[0056] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the battery module 111 includes a first battery sub-module 1111 and a second battery sub-module 1112 arranged sequentially along the cooling airflow direction of the first air inlet 11210; a first gap 10 is provided between the first battery sub-module 1111 and the second battery sub-module 1112; and a second baffle plate 113 is located on one side of the first gap 10 and above the second battery sub-module 1112.

[0057] In this embodiment, the first battery submodule 1111 corresponds to the first air intake space, and the second battery submodule 1112 corresponds to the second air intake space. A first gap 10 exists between the first battery submodule 1111 and the second battery submodule 1112. Since the second baffle 113 is located on one side of the first gap and above the second battery submodule 1112, the cooling air blocked by the second baffle 113 can descend through the first gap 10 into the space between the first battery submodule 1111 and the second battery submodule 1112. Furthermore, under the action of the respective exhaust fans of the first battery submodule 1111 and the second battery submodule 1112, the air enters the interior of the first battery submodule 1111 and the second battery submodule 1112 for cooling, enhancing the cooling of the battery pack near the first gap 10 and thus improving the overall heat dissipation efficiency of the battery pack. That is, the second baffle 113 achieves a uniform distribution of cooling air between the first and second air intake spaces, and the position of the second baffle 113 does not obstruct the cooling air from further flowing downwards into the battery module.

[0058] Optionally, the number of battery packs in the first battery submodule 1111 and the second battery submodule 1112 can be the same or different, for example, as shown in the example. Figure 3 As shown, the first battery submodule 1111 includes 6 battery packs, and the second battery submodule 1112 includes 6 battery packs.

[0059] In some embodiments of this application, such as Figure 2-3 , Figure 7 and Figure 8 As shown, there is a second gap 20 between the battery module 111 and the first end face 1001, and the energy storage container also includes:

[0060] The third baffle plate 114 is disposed at the first air inlet 11210 and partially overlaps with the first air inlet 11210; there is a gap between the third baffle plate 114 and the first air inlet 11210, which communicates with the second gap 20; part of the cooling air entering from the first air inlet 11210 is blocked by the third baffle plate 114 and flows downward into the second gap 20.

[0061] In this embodiment, a third baffle plate 114 is provided at the first air inlet 11210. The third baffle plate 114 partially overlaps with the first air inlet 11210, thereby partially blocking the cooling air entering the first air inlet 11210. This partial overlap can be achieved by having the third baffle plate 114 partially block the first air inlet 11210 in the width direction. Preferably, the height H3 of the third baffle plate 114 is greater than or equal to the height of the first air inlet 11210, ensuring that the blocked width portion of the first air inlet 11210 is completely blocked in the height direction, thus guaranteeing that sufficient cooling air is blocked and enters the second gap 20. Alternatively, the third baffle 114 can partially obstruct the first air inlet 11210 in the height direction, achieving partial overlap with the first air inlet 11210. Preferably, the lower portion of the first air inlet 11210 is obstructed, and this obstructed height portion is completely obstructed in the width direction, ensuring that sufficient cooling air is blocked and enters the second gap 20. Alternatively, the third baffle 114 can have ventilation holes or notches to achieve partial overlap with the first air inlet 11210.

[0062] Because there is a gap between the third baffle plate 114 and the first air inlet 11210 that communicates with the second gap 20, part of the cooling air blocked by the third baffle plate 114 can enter the second gap 20 through the gap, and further enter the battery module under the action of the exhaust fan of the battery module 111 to cool the battery pack at the second gap 20, thereby improving the heat dissipation efficiency of the entire battery pack.

[0063] In some embodiments of this application, the first air inlet 11210 is located in the first axial direction between the first end face 1001 and the battery module 111, that is, the first air inlet 11210 is located above the second gap 20; the bottom of the third baffle 114 is connected to the top of the battery module 111, preferably connected to the top edge of the battery module 111, and the top of the third baffle 114 can be connected to the top surface, or the top of the third baffle 114 can also be connected to the top of the first baffle 112, so that the third baffle 114 can allow part of the cooling air entering from the first air inlet 11210 to enter the second gap 20 through the gap, and improves the flexibility of the installation method of the third baffle 114.

[0064] In some embodiments of this application, such as Figure 7 As shown, the first air inlet 11210 includes two first sub-air inlets 11211 arranged side by side, and the third baffle 114 is located between the two first sub-air inlets 11211, and the third baffle 114 partially overlaps with the two first sub-air inlets 11211.

[0065] In this embodiment, the first air inlet 11210 includes two first sub-air inlets 11211 arranged side by side along the first axial direction, making the cooling air entering the air intake space more uniform along the first axial direction. Since the third baffle 114 is located between the two first sub-air inlets 11211 and partially overlaps with them, the third baffle 114 can simultaneously partially block the cooling air entering the two first sub-air inlets 11211, thereby making the cooling air entering the air intake space more uniform. Optionally, the third baffle 114 can partially block the two first sub-air inlets 11211 in the width direction, achieving partial overlap with the two first sub-air inlets 11211 (e.g., ...). Figure 7 (as shown in the image). Preferably, as... Figure 10 As shown, the width of the third baffle plate 114 is W, the width of the first sub-air inlet 11211 is D1, and the width of the first sub-air inlet 11211 blocked by the third baffle plate 114 is D2. D2 / D1 = 0.2 to 0.3, preferably D2 / D1 = 0.23, or D2 / D1 = 0.24, or D2 / D1 = 0.25.

[0066] Alternatively, the third baffle 114 can partially obstruct the two first sub-inlets 11211 in the height direction, achieving partial overlap with the two first sub-inlets 11211. In some embodiments of this application, the third baffle 114 obstructs the two first sub-inlets 11211 to the same degree. This makes the airflow entering the air intake space from each of the first sub-inlets 11211 more balanced, further improving the uniformity of the cooling air entering the air intake space.

[0067] In some embodiments of this application, corresponding to the two first sub-air inlets 11211, there may also be two third baffles 114, each of which blocks a portion of a first sub-air inlet 11211.

[0068] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the first wind deflector 112 includes:

[0069] An end plate 1121 is provided along the top edge of the first end face 1001, and a first air inlet 11210 is provided on the end plate 1121;

[0070] The first side plate 1122 is provided along the upper edge of the first side surface 1003. One end of the first side plate 1122 is connected to the end plate 1121 and the other end is connected to the second end surface 1002.

[0071] The second side plate 1123 is provided along the upper edge of the second side surface 1004. One end of the second side plate 1123 is connected to the end plate 1121 and the other end is connected to the second end face 1002.

[0072] The first side plate 1122 has a second air inlet 11220 for cooling air to enter, and the second side plate 1123 has a third air inlet 11230 for cooling air to enter.

[0073] In this embodiment, the first baffle plate 112 includes an end plate 1121, a first side plate 1122, and a second side plate 1123. The end plate 1121 has a first air inlet 11210, the first side plate 1122 has a second air inlet 11220, and the second side plate 1123 has a third air inlet 11230. This allows cooling air to enter the air intake space from three positions—the end plate, the first side plate, and the second side plate—while simultaneously surrounding the air intake space. This ensures that the cooling air reliably covers the battery module, preventing it from overflowing directly without passing through the battery module 111 and failing to cool it. By setting up the first baffle plate, the uniformity of the cooling air entering the air intake space is improved, thereby dissipating heat from the battery module 111 more efficiently and evenly.

[0074] In some embodiments of this application, the second air inlet 11220 and the third air inlet 11230 are staggered, so that the cooling air enters different areas in the air intake space through the second air inlet 11220 and the third air inlet 11230 respectively. For example, the cooling air enters the second air intake space through the second air inlet 11220 and the cooling air enters the first air intake space through the third air inlet 11230, which further improves the uniformity of the cooling air in the air intake space.

[0075] In some embodiments of this application, the tops of the end plate 1121, the first side plate 1122, and the second side plate 1123 are all connected to the top surface; the bottoms of the first side plate 1122 and the second side plate 1123 are all connected to the top of the battery module 111. The end plate 1121 is located in the first axial direction between the first end face 1001 and the battery module 111, that is, the end plate 1121 is located in the first axial direction above the second gap 20 between the first end face 1001 and the battery module 111, so that the first air inlet 11210 is located above the second gap 20, and the gap between the first air inlet 11210 and the third baffle plate 114 can achieve communication with the second gap 20.

[0076] In this embodiment, the tops of the end plate 1121, the first side plate 1122, and the second side plate 1123 can be connected to the top surface by welding, screws, riveting, etc., and the bottoms of the first side plate 1122 and the second side plate 1123 can be connected to the top of the battery module 111. This improves the stability of the first wind deflector 112 while allowing the first wind deflector 112 to cooperate with the top surface and the second end surface 1002 to form an air intake space. A second gap 20 exists between the battery module 111 and the first end face 1001. The bottom of the end plate 1121 is not connected to the top of the battery module 111. The end plate 1121 is located in the first axial direction between the end face 1001 and the end face of the battery module 111, such that the first air inlet 11210 is located above the second gap 20, and the third baffle plate 114 is located above the battery module 111. This ensures that the gap between the first air inlet 11210 and the third baffle plate 114 can communicate with the second gap 20. Cooling air entering the air intake space from the first air inlet 11210 on the end plate 1121 can enter the second gap 20 through the gap between the first air inlet 11210 and the third baffle plate 114, thereby cooling the battery pack near the first end face 1001. Optionally, the bottom of the end plate 1121 can be connected to the first end face 1001 by welding, screws, riveting, or other methods.

[0077] In some embodiments of this application, such as Figure 7 As shown, one end of the second baffle 113 is fixedly connected to the first side plate 1122, and the other end is fixedly connected to the second side plate 1123. The bottom of the second baffle 113 can be connected to the top of the battery module 111, allowing cooling air to enter the second air intake space through the gap between the top of the second baffle 113 and the top surface of the first space 110. Alternatively, the top of the second baffle 113 can also be connected to the top surface of the first space 110, allowing cooling air to enter the second air intake space through the gap between the bottom of the second baffle 113 and the top of the battery module. Alternatively, the second baffle 113 is located vertically at... The top surface of the first space 110 and the top surface of the battery module are connected by gaps, such that there are gaps between the top of the second baffle 113 and the top surface of the first space 110, and between the bottom of the second baffle 113 and the top of the battery module. These gaps allow cooling air to enter the second air intake space, ensuring that some cooling air remains in the first air intake space due to the obstruction of the second baffle 113, while also ensuring that an appropriate amount of cooling air can enter the second air intake space through these gaps. This improves the uniformity of cooling air in the air intake space and enhances the stability and installation flexibility of the second baffle 113.

[0078] In some embodiments of this application, such as Figure 8As shown, both ends of the second baffle 113 have notches 1130 for wiring to pass through. Wiring related to the battery module 111 can be assembled through these notches 1130, improving the wiring assembly efficiency of the energy storage container. Furthermore, since the notches 1130 are not sealed when the wiring passes through them, some cooling air also passes through the notches 1130 from the first air intake space into the second air intake space.

[0079] In some embodiments of this application, the battery module 111 includes a first battery sub-module 1111 and a second battery sub-module 1112 arranged sequentially along the cooling airflow direction of the first air inlet 11210; the second air inlet 11220 faces the second battery sub-module 1112, and the third air inlet 11230 faces the first battery sub-module 1111.

[0080] In this embodiment, as Figure 9 As shown, the cooling air entering from the first air inlet 11210 and the third air inlet 11230 first enter the first air intake space. After some of the cooling air sinks, it cools the first battery submodule 1111. The other part of the cooling air in the first air intake space, driven by the cooling air entering from the first air inlet 11210, enters the second air intake space through the second baffle 113. In the second air intake space, it sinks together with the cooling air entering from the second air inlet 11220 to cool the second battery submodule. Block 1112 is used for cooling, and a portion of the cooling air enters the first gap 10 between the first battery sub-module 1111 and the second battery sub-module 1112 through the second baffle 113. It is then drawn into the battery module through the first gap 10, thereby cooling the battery pack near the first gap 10. In this way, the uniformity of the cooling air entering the air intake space is improved by the cooperation of the first air inlet 11210, the second air inlet 11220, the third air inlet 11230 and the second baffle 113.

[0081] In some embodiments of this application, such as Figure 4 , Figure 6 and Figure 9 As shown, the energy storage container also includes an end cooling module 201 disposed on the first end face 1001, a first side cooling module 202 disposed on the first side face 1003, and a second side cooling module 203 disposed on the second side face 1004; the cooling air outlet of the end cooling module 201 is connected to the first air inlet 11210; the cooling air outlet of the first side cooling module 202 is connected to the second air inlet 11220; and the cooling air outlet of the second side cooling module 203 is connected to the third air inlet 11230.

[0082] In this embodiment, refrigeration equipment such as air conditioners can be used as the end cooling module 201, the first side cooling module 202, and the second side cooling module 203. The end cooling module 201 can blow cooling air into the air intake space through the first air inlet 11210, the first side cooling module 202 can blow cooling air into the air intake space through the second air inlet 11220, and the second side cooling module 203 can blow cooling air into the air intake space through the third air inlet 11230. Thus, by providing cooling air to the air intake space through three sets of cooling modules, the cooling air to the air intake space can be provided more reliably, and the uniformity of cooling air in the air intake space can be improved.

[0083] In some embodiments of this application, as an alternative, the third air inlet 11230 and the second air inlet 11220 can both be disposed on the first side plate 1122, and the first side cooling module 202 and the second side cooling module 203 can both be disposed on the first side 1003. Alternatively, the second air inlet 11220 and the third air inlet 11230 can both be disposed on the second side plate 1123, and the first side cooling module 202 and the second side cooling module 203 can both be disposed on the second side 1004. Thus, the corresponding cooling module can be disposed only on one of the first side 1003 or the second side 1004, so as to provide cooling air to the air intake space more flexibly.

[0084] In some embodiments of this application, such as Figures 3-6 As shown, the first battery submodule 1111 and the second battery submodule 1112 are staggered in the first axial direction to form a space between the first battery submodule 1111 and the second side surface 1004 to accommodate the second side cooling module 203, and a space between the second battery submodule 1112 and the first side surface 1003 to accommodate the first side cooling module 202. In the first axial direction, the projected portions of the first battery submodule 1111 and the first side cooling module 202 coincide, and the projected portions of the second battery submodule 1112 and the second side cooling module 203 coincide.

[0085] In this embodiment, by staggering the first battery submodule 1111 and the second battery submodule 1112 along the first axial direction, the first side cooling module 202 and the second side cooling module 203 are assembled through staggered spaces, which improves the utilization rate of the first space 110, makes the overall space of the energy storage container more compact and smaller in size, and improves the assembly efficiency of the first side cooling module 202 and the second side cooling module 203.

[0086] In some embodiments of this application, such as Figure 1As shown, the container 100 also includes a second space 120. The first space 110 and the second space 120 are arranged sequentially along a first axis, and the second end face 1002 separates the first space 110 and the second space 120 from each other. The first side 1003 of the first space 110 is also the first side of the second space 120, and the second side 1004 of the first space 110 is also the second side of the second space 120. The top surface of the first space 110 is also the top surface of the second space 120. The energy storage container also includes:

[0087] An electrical module 121 is disposed in the second space 120 and is used to control the charging and discharging of the battery module 111.

[0088] The housing 100 also has a bottom surface 130; the bottom surface 130 is located below the first space 110 and the second space 120, and is used to support the first space 110 and the components therein, and to support the second space 120 and the components therein.

[0089] In this embodiment, the first space 110 and the second space 120 are separated from each other by the second end face 1002, so that the electrical module 121 will not be damaged in the event of leakage from the battery module 111, thus improving reliability. Furthermore, the second end face 1002 provides the battery module 111 with an independent cooling space, where cooling air circulates, ensuring the cooling effect of the battery module 111 and reducing the energy consumption of the end cooling module 201, the first side cooling module 202, and the second side cooling module 203. The bottom surface 130 provides protection and support for the components within the container 100, while also facilitating the movement of the energy storage container to a designated location.
