[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0064] An energy storage cabinet is an integrated energy storage and management system. It can store and release electrical energy, enabling flexible scheduling of electrical energy. The energy storage cabinet includes a cabinet body, which contains battery modules, a battery management system (BMS), connecting pipelines, etc. The cabinet body can also be equipped with auxiliary equipment such as fire-fighting components and lighting components. The front of the cabinet body is an opening, which can be opened or closed to open or close the cabinet body.

[0065] Currently, when there are multiple battery modules, multiple energy storage cabinets are required. For example, when there are two battery modules, two energy storage cabinets are required, which increases the number of energy storage cabinets needed and consequently increases the cost of the energy storage cabinets.

[0066] To overcome the shortcomings of the prior art, this application provides an energy storage cabinet, including a cabinet with a cavity, a first opening, and a second opening. The cavity can accommodate at least two battery modules. The first and second openings are both connected to the cavity and are located on opposite sides of the cabinet. That is, the cabinet of this application does not have a back panel. When using existing energy storage cabinets to accommodate at least two battery modules, at least two existing energy storage cabinets are required because they have back panels, consuming at least two back panel materials. Compared to using multiple existing energy storage cabinets, the energy storage cabinet of this application not only reduces the number of cabinets but also reduces the material consumption by at least two back panel materials. Therefore, when accommodating at least two battery modules, the energy storage cabinet of this application consumes less material, resulting in a lower cost. Furthermore, multiple battery modules can fully utilize the space within the cabinet, increasing space utilization and making the structure of the energy storage cabinet more compact.

[0067] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0068] The specific structure of the energy storage cabinet in the embodiments of this application and various possible implementation methods are described in detail below.

[0069] In the embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this application provides an energy storage cabinet, including a cabinet 100. The cabinet 100 has a cavity 110, a first opening 120 and a second opening 130. The cavity 110 is used to accommodate at least two battery modules 400. The first opening 120 and the second opening 130 are both connected to the cavity 110. The first opening 120 and the second opening 130 are located on opposite sides of the cabinet 100.

[0070] At least two battery modules 400 are disposed within the cavity 110 along a first direction, which is parallel to the direction from the first opening 120 to the second opening 130.

[0071] It should be noted that the accompanying drawings of this application embodiment illustrate the use of two battery modules 400 as an example. Of course, the energy storage cabinet of this application embodiment can also accommodate more than two battery modules 400.

[0072] Both the first opening 120 and the second opening 130 are connected to the cavity 110, so that at least one battery module 400 can enter the cavity 110 through the first opening 120 and at least one battery module 400 can enter the cavity 110 through the second opening 130.

[0073] The first opening 120 and the second opening 130 are located on opposite sides of the cabinet 100. For example, if the first opening 120 is located on the front of the cabinet 100, then the second opening 130 is located on the back of the cabinet 100; if the first opening 120 is located on the left side of the cabinet 100, then the second opening 130 is located on the right side of the cabinet 100.

[0074] The first opening 120 and the second opening 130 can be the same or different in size. The first opening 120 and the second opening 130 can be aligned, or they can be offset. The offset can be vertical or horizontal.

[0075] Each battery module 400 is disposed within the cavity 110 along a first direction, which is parallel to the direction from the first opening 120 to the second opening 130. For example, if the first opening 120 is located on the front side of the cabinet 100 and the second opening 130 is located on the rear side of the cabinet 100, then the first direction is the direction from the front side of the cabinet 100 to the rear side of the cabinet 100. Furthermore, if the first opening 120 and the second opening 130 are aligned, the first direction is the direction from the front side of the cabinet 100 to the rear side of the cabinet 100, and the first direction is horizontal.

[0076] Because the first opening 120 and the second opening 130 are located on opposite sides of the cabinet 100, the cabinet 100 of the energy storage cabinet in this embodiment of the application does not have a back panel. When using an existing energy storage cabinet to accommodate at least two battery modules 400, at least two existing energy storage cabinets are required. Since the existing energy storage cabinet has a back panel, at least two back panel materials will be consumed. Compared with using multiple existing energy storage cabinets, using the energy storage cabinet of this embodiment of the application not only reduces the number of energy storage cabinets, but also reduces the material consumption of at least two back panel materials. That is, when accommodating at least two battery modules 400, the energy storage cabinet of this embodiment of the application consumes less material, and the material cost of the energy storage cabinet is lower.

[0077] Furthermore, the multiple battery modules 400 are housed within the cavity 110 of a cabinet 100, which allows for full utilization of the space within the cavity 110, resulting in higher space utilization. Consequently, the structure of the energy storage cabinet of this application can be made more compact.

[0078] It should be noted that a battery management system 10 is also installed inside the cavity 110, and the battery management system 10 is electrically connected to the battery module 400.

[0079] In another embodiment, reference is made to Figure 1 As shown, the energy storage cabinet also includes a first door 200 and a second door 300, which are movably connected to the cabinet 100 and configured to open and close a first opening 120; the second door 300 is movably connected to the cabinet 100 and configured to open and close a second opening 130.

[0080] In this embodiment, the first door 200 is set to open and close the first opening 120, and the second door 300 is set to open and close the second opening 130.

[0081] Specifically, the first door 200 can be movably connected to the first opening 120 by means of hinge, magnetic connection, snap-fit, etc. For example, it can be hinged to the first opening 120 by a hinge. The second door 300 is similar, and will not be described in detail here.

[0082] In other embodiments, refer to Figure 1 As shown, the first opening 120 and the second opening 130 are positioned opposite each other, and the first opening 120 and the second opening 130 are the same size.

[0083] In this embodiment, for example, if the first opening 120 is located on the front side of the cabinet 100, then the second opening 130 is located on the rear side of the cabinet 100, and the first opening 120 and the second opening 130 correspond to each other and are the same size. Thus, the battery module 400 entering the cavity 110 through the first opening 120 and the battery module 400 entering the cavity 110 through the second opening 130 can be set to the same size, ensuring that the battery modules 400 entering the cavity 110 through the first opening 120 and the battery module 400 entering the cavity 110 through the second opening 130 are at the same horizontal height, making the force on the cabinet 100 more uniform and improving the stability of the cabinet 100.

[0084] In another possible embodiment, refer to Figure 1 As shown, the energy storage cabinet also includes an intake valve 500 and an exhaust valve 600, both of which are located in the cabinet 100.

[0085] In this embodiment, the intake valve 500 and the exhaust valve 600 are key components for maintaining the safe and stable operation of the energy storage cabinet. Their functions are mainly reflected in pressure regulation, safety assurance and system maintenance.

[0086] The air inlet valve 500 introduces clean gas (such as nitrogen or compressed air) into the cabinet 100 to ensure that the pressure inside the cabinet 100 is higher than that of the external environment, forming a positive pressure barrier to prevent the intrusion of external flammable and explosive gases or dust, and to avoid explosions caused by external hazardous substances coming into contact with electrical equipment inside the cabinet.

[0087] When the pressure inside the cabinet exceeds the preset safety value, the exhaust valve 600 opens to quickly release the gas and avoid the risk of explosion due to excessive pressure.

[0088] The intake valve 500 and the exhaust valve 600 work together. When the pressure inside the cabinet is lower than the safety threshold, the intake valve 500 replenishes gas to restore the pressure; conversely, if the pressure is too high, the exhaust valve 600 is activated to release gas, thus forming a dynamic balance.

[0089] It should be noted that the intake valve 500 and exhaust valve 600 can be installed on the cabinet 100 or on the door. For example, both the intake valve 500 and exhaust valve 600 can be installed on the cabinet 100, or both the intake valve 500 and exhaust valve 600 can be installed on the first door 200 or the second door 300. Alternatively, the intake valve 500 and exhaust valve 600 can be installed on different doors, or either the intake valve 500 or exhaust valve 600 can be installed on the cabinet 100, and either the exhaust valve 600 or intake valve 500 can be installed on the door.

[0090] It should be noted that in existing energy storage cabinets, each cabinet is equipped with a set of inlet valves 500 and exhaust valves 600. When the number of battery modules 400 is increased, a corresponding number of energy storage cabinets need to be added, which in turn requires a corresponding number of inlet valves 500 and exhaust valves 600, thus increasing the cost of the inlet valves 500 and exhaust valves 600. However, when using the energy storage cabinet of this application, since the energy storage cabinet only has one set of inlet valves 500 and exhaust valves 600, the cost of the energy storage cabinet of this application is lower than that of the existing multiple energy storage cabinets, thereby further reducing the cost of the energy storage cabinet.

[0091] In other possible embodiments, refer to Figure 1 As shown, the intake valve 500 is located on the first door body 200, and the exhaust valve 600 is located on the second door body 300.

[0092] In this embodiment, since the first door 200 and the second door 300 are located on opposite sides of the cabinet 100, the air intake valve 500 and the exhaust valve 600 are located on opposite sides of the cabinet 100, which can ensure smoother exhaust.

[0093] Furthermore, refer to Figure 1 As shown, the intake valve 500 is located above the first door 200, and the exhaust valve 600 is located below the second door 300.

[0094] In this embodiment, the intake valve 500 and the exhaust valve 600 are arranged diagonally opposite each other on the cabinet 100, which facilitates the rapid discharge of gas from the entire cabinet 100, avoids the presence of residual gas in the cabinet 100, and further improves the smoothness of exhaust.

[0095] In one embodiment, reference is made to... Figure 2 As shown, the energy storage cabinet also includes a fire suppression system 700, which is disposed in the cabinet 100 and configured to detect at least one of smoke and temperature within the cavity 110.

[0096] In this embodiment, the fire-fighting component 700 can detect at least one of smoke and temperature in the cavity 110, and the fire-fighting component 700 allows the user to observe the smoke and temperature conditions in the cavity 110 in real time.

[0097] Furthermore, information such as smoke and temperature inside the detection cavity 110 can be transmitted to the controller, which can then activate the fire-fighting cooling equipment to cool and extinguish the fire inside the cavity 110. The controller can also control the alarm equipment to issue an alarm and remind the user to take emergency measures.

[0098] It should be noted that in existing energy storage cabinets, each cabinet is equipped with a fire suppression component 700. Increasing the number of battery modules 400 requires increasing the number of energy storage cabinets, which in turn requires an additional number of fire suppression components 700, thus increasing the cost of the fire suppression components 700. However, when using the energy storage cabinet of this application, since the energy storage cabinet of this application has only one fire suppression component 700, the cost of the energy storage cabinet of this application is lower than that of the existing multiple energy storage cabinets, thereby further reducing the cost of the energy storage cabinet.

[0099] In another embodiment, the fire protection component 700 includes a smoke detector and a temperature detector, both of which are disposed in the cavity 110. The smoke detector is configured to detect smoke in the cavity 110, and the temperature detector is configured to detect the temperature in the cavity 110.

[0100] In this embodiment, the smoke detector can be a smoke sensor, and the temperature detector can be a temperature sensor. When the smoke concentration in the cavity 110 is higher than a preset value, the smoke detector can issue an alarm. When the temperature in the cavity 110 is higher than a preset value, the temperature detector can issue an alarm to remind the user to take emergency measures.

[0101] Furthermore, refer to Figure 1 As shown, both the first door body 200 and the second door body 300 are equipped with explosion relief valves 800.

[0102] The explosion relief valve 800 is a core safety device that ensures the safe operation of energy storage systems. It is mainly used to deal with the problem of sudden pressure rise under extreme conditions such as battery thermal runaway and combustion explosion. The explosion relief valve 800 has functions such as rapid pressure relief, suppression of explosion spread, and protection of equipment integrity.

[0103] In this embodiment, since both the first door 200 and the second door 300 are equipped with explosion relief valves 800, the explosion relief valve 800 on the first door 200 relieves pressure and protects the battery module 400 entering through the first opening 120, and the explosion relief valve 800 on the second door 300 relieves pressure and protects the battery module 400 entering through the second opening 130, resulting in faster pressure relief and higher safety.

[0104] In some embodiments, reference is made to Figure 3 , Figure 4 and Figure 6 As shown, the energy storage cabinet also includes a positioning component 111, which is disposed in the cavity 110 and engages with the battery module 400 in the first direction.

[0105] In this embodiment, since the battery module 400 is disposed in the cavity 110 along the first direction, when the battery module 400 moves in the first direction, for example, when the battery module 400 moves from the first opening 120 to the second opening 130, when it has moved a predetermined distance, the positioning member 111 will cooperate with the battery module 400. At this time, the positioning member 111 will limit the battery module 400, restricting the battery module 400 from continuing to move from the first opening 120 to the second opening 130, so as to avoid collision between the battery module 400 entering from the first opening 120 and the battery module 400 entering from the second opening 130, thus ensuring the safety of the battery module 400.

[0106] In some possible embodiments, refer to Figure 3 , Figure 4 and Figure 6 As shown, the battery module 400 has a positioning groove 430, and the positioning member 111 is movably embedded in the positioning groove 430. The positioning groove 430 is arranged along a first direction.

[0107] In this embodiment, for example, when the battery module 400 moves from the first opening 120 to the second opening 130, and moves a predetermined distance, the positioning member 111 will be embedded in the positioning groove 430. At this time, the positioning member 111 restricts the battery module 400 from continuing to move from the first opening 120 to the second opening 130 through the positioning groove 430. At this time, the positioning groove 430 cannot move from the first opening 120 to the second opening 130, that is, it cannot continue to move forward, but can only move from the second opening 130 to the first opening 120, that is, it can only move backward.

[0108] Specifically, the positioning element 111 can be a protrusion that matches the positioning groove 430.

[0109] In another possible embodiment, refer to Figure 6 and Figure 11 As shown, the positioning member 111 is located on the bottom wall of the cavity 110, and the positioning groove 430 is located at the bottom of the battery module 400, so that the positioning member 111 and the battery module 400 are in upper limit engagement in the second direction, which is perpendicular to the first direction and perpendicular to the height direction of the cabinet 100.

[0110] It should be noted that the first direction is parallel to the direction from the first opening 120 to the second opening 130. In this embodiment, the first direction can be the front-to-back direction of the cabinet 100, because the second direction is perpendicular to the first direction and also perpendicular to the height direction of the cabinet 100. That is, the second direction is the left-to-right direction of the cabinet 100.

[0111] In this embodiment, when the positioning member 111 is embedded in the positioning groove 430, the left and right sides of the positioning member 111 abut against the left and right sides of the positioning groove 430 respectively. At this time, the battery module 400 cannot move to the left or right relative to the positioning member 111. Furthermore, because the positioning member 111 is located on the bottom wall of the cavity 110 and the positioning groove 430 is located at the bottom of the battery module 400, when the positioning member 111 is embedded in the positioning groove 430, the positioning groove 430 and the bottom wall of the cavity 110 will prevent the battery module 400 from moving up or down relative to the positioning member 111. That is, when the positioning member 111 is embedded in the positioning groove 430, the positioning member 111 limits the battery module 400 in the forward, upward, downward, left, or right directions. At this time, the battery module 400 can only move backward.

[0112] Furthermore, refer to Figure 6 As shown, the positioning groove 430 is a U-shaped groove with the U-shaped opening facing the positioning member 111 so that the positioning member 111 can be inserted into the U-shaped groove.

[0113] In some embodiments, reference is made to Figure 3 and Figure 4 As shown, there are multiple positioning elements 111 and multiple positioning slots 430, with the multiple positioning elements 111 being movably embedded in the multiple positioning slots 430 respectively.

[0114] In this embodiment, each positioning element 111 is movably embedded in each positioning groove 430, thereby making the positioning element 111 more stable in limiting the battery module 400 and ensuring more reliable limiting of the battery module 400.

[0115] In another embodiment, reference is made to Figure 7 , Figure 8 and Figure 9 As shown, the energy storage cabinet also includes a first fixing member 112, which is disposed in the cavity 110, connected to the cabinet 100, and detachably connected to the battery module 400.

[0116] In this embodiment, after the battery module 400 is housed in the cavity 110, the battery module 400 can be fixed in the cavity 110 by the first fixing member 112 to prevent the battery module 400 from shaking or loosening in the cavity 110.

[0117] Specifically, the first fastener 112 can be a snap-fit ​​component, a magnetic component, a bolt connector, etc.

[0118] In other embodiments, refer to Figure 7 , Figure 8 and Figure 9As shown, there are multiple first fixing members 112. Multiple first fixing members 112 are connected to two opposing inner walls of the cavity 110 in the second direction. Multiple first fixing members 112 are also connected to opposite sides of the battery module 400 in the second direction.

[0119] In this embodiment, the two inner walls of the cavity 110 that are opposite each other in the second direction are the inner walls of the left and right sides of the cabinet 100, that is, a plurality of first fixing members 112 are provided on the inner walls of the left and right sides of the cabinet 100.

[0120] In one embodiment, reference is made to... Figure 7 As shown, multiple first fasteners 112 are also distributed at intervals along the height direction of the cabinet 100.

[0121] In this embodiment, multiple first fixing members 112 are connected to the battery module 400 at intervals along the height direction of the battery module 400, thereby avoiding the phenomenon of the battery module 400 tilting up and down, and making the battery module 400 more stable in the cavity 110.

[0122] In another embodiment, reference is made to Figure 3 , Figure 10 and Figure 12 As shown, the energy storage cabinet also includes a first support beam 113, which is disposed in the cavity 110 and connected to the cabinet 100. The first support beam 113 is located between at least two battery modules 400.

[0123] In this embodiment, the side of the first support beam 113 facing the first opening 120 can support the battery module 400 entering through the first opening 120, and the side of the first support beam 113 facing the second opening 130 can support the battery module 400 entering through the second opening 130. Furthermore, the first support beam 113 can prevent the battery module 400 entering through the first opening 120 from moving, tilting, or tipping over, or prevent the battery module 400 entering through the second opening 130 from moving, tilting, or tipping over, thus preventing the battery module 400 entering through the first opening 120 and the battery module 400 entering through the second opening 130 from colliding with each other, thereby improving the safety of the battery module 400.

[0124] In some possible embodiments, refer to Figure 4 , Figure 5 and Figure 12As shown, the battery module 400 includes a module body 410 and a support block 420. One end of the support block 420 is connected to the module body 410, and the other end of the support block 420 abuts against the first support beam 113 so that there is a gap between the module body 410 and the first support beam 113.

[0125] In this embodiment, the support block 420 creates a gap between the module body 410 and the first support beam 113, which facilitates the installation of other components, such as pipes, within the gap. The gap also serves a heat dissipation function, improving the heat dissipation effect on the battery module 400 entering from the first opening 120 and the battery module 400 entering from the second opening 130. Furthermore, it prevents a large amount of heat from the battery module 400 entering from the first opening 120 from being transferred to the battery module 400 entering from the second opening 130, or vice versa.

[0126] Furthermore, the material of the support block 420 can be set as a buffer material. The buffer material has the function of absorbing kinetic energy, thereby preventing a large amount of force from the first support beam 113 from being transmitted to the battery module 400 and causing damage to the battery module 400.

[0127] In another possible embodiment, refer to Figure 3 , Figure 10 and Figure 13 As shown, the first support beam 113 is arranged along the height direction of the cabinet 100, and there are multiple support blocks 420. The multiple support blocks 420 abut against various parts of the first support beam 113 along the height direction of the cabinet 100.

[0128] In this embodiment, the first support beam 113 extends along the height direction of the cabinet 100. Specifically, the first support beam 113 can be vertically installed inside the cabinet 100. Multiple support blocks 420 are spaced apart along the height direction of the module body 410. The multiple support blocks 420 respectively abut against each part of the first support beam 113 along the height direction of the cabinet 100.

[0129] In other embodiments, refer to Figure 3 As shown, the energy storage cabinet also includes a second support beam 114, which is disposed in the cavity 110 and connected to the cabinet 100. The second support beam 114 is connected to the first support beam 113, and the second support beam 114 and the first support beam 113 are arranged at an angle.

[0130] In this embodiment, the second support beam 114 has a fixing and reinforcing effect on the first support beam 113, making the first support beam 113 more stable and preventing the first support beam 113 from tilting or shifting.

[0131] Furthermore, refer to Figure 3 As shown, the second support beam 114 is perpendicular to the first support beam 113, so that the second support beam 114 and the first support beam 113 together support the upper, lower, left and right sidewalls of the cavity 110, preventing the cavity 110 from collapsing.

[0132] In one embodiment, reference is made to... Figure 13 and Figure 14 As shown, the energy storage cabinet also includes a second fixing member 115, which is connected to the top of the battery module 400 and to the first support beam 113.

[0133] In this embodiment, the second fixing member 115 fixes the top of the battery module 400, preventing the top of the battery module 400 from becoming loose. Under the combined action of the first fixing member 112 and the second fixing member 115, the upper, left, and right ends of the battery module 400 are all fixed. Under the action of the first support beam 113 and the positioning member 111, the rear end of the battery module 400 is limited. Under the action of the bottom wall of the cavity 110, the lower end of the battery module 400 is limited. Under the combined action of the first fixing member 112, the second fixing member 115, the first support beam 113, the positioning member 111, and the inner wall of the cavity 110, the battery module 400 is limited and fixed in the designated position.

[0134] It should be noted that the second fastener 115 can be a bolt connection assembly, riveting assembly, snap-fit ​​assembly, welding assembly, magnetic connection assembly, etc.

[0135] In another embodiment, reference is made to Figure 13 and Figure 14 As shown, the second fastener 115 is connected to the side of the battery module 400 adjacent to the first support beam 113.

[0136] In this embodiment, the first support beam 113 is connected to both the side facing the first opening 120 and the side facing the second opening 130 by a second fixing member 115. This is because the side of the first support beam 113 facing the first opening 120 supports the battery module 400 entering through the first opening 120, and the side of the first support beam 113 facing the second opening 130 supports the battery module 400 entering through the second opening 130. Therefore, the second fixing member 115 connected to the side of the first support beam 113 facing the first opening 120 is connected to... The battery module 400 entering through the first opening 120 is connected to the top of the first support beam 113. The second fastener 115 connected to the side of the first support beam 113 facing the second opening 130 is connected to the top of the battery module 400 entering through the second opening 130. That is, the first support beam 113 serves to support the battery module 400 entering through the first opening 120 and the battery module 400 entering through the second opening 130, and also serves to connect the battery module 400 entering through the first opening 120 and the battery module 400 entering through the second opening 130.

[0137] In another possible embodiment, refer to Figure 13 , Figure 14 and Figure 15 As shown, the cabinet 100 has an openable and closable mounting opening 140, which is located at the top of the cabinet 100, and at least part of the mounting opening 140 is opposite to the second fastener 115.

[0138] In this embodiment, an installation port 140 is provided on the top of the cabinet 100, so that workers or robotic arms can easily reach into the interior of the cabinet 100 and connect and fix the top of the battery module 400 to the first support beam 113 through the second fastener 115.

[0139] Furthermore, a switch door is provided on the mounting port 140, which is used to open and close the mounting port 140. After the battery module 400 is fixed, the switch door can be closed.

[0140] Furthermore, refer to Figure 13 , Figure 14 and Figure 15 As shown, there are multiple mounting ports 140 and multiple second fasteners 115, and each mounting port 140 corresponds to each second fastener 115. Furthermore, each mounting port 140 and each second fastener 115 are arranged at intervals along the width direction of the cabinet 100.

[0141] In this embodiment, the width direction of the cabinet 100 is the left-right direction of the cabinet 100, which is the second direction. By setting multiple mounting openings 140 and second fasteners 115 arranged at intervals along the width direction of the cabinet 100, it is ensured that the cabinet 100 will not tilt in the left-right direction, making the cabinet 100 more stable.

[0142] In another embodiment, reference is made to Figure 15 and Figure 16 As shown, the energy storage cabinet also includes a third fixing member 116, which is connected to the bottom wall of the cavity 110 and is connected to the battery module 400.

[0143] In this embodiment, the battery module 400 is fixed to the bottom wall of the cavity 110 by the third fastener 116.

[0144] Furthermore, refer to Figure 15 and Figure 16 As shown, the third fastener 116 is connected to the bottom of the battery module 400. This secures the top, bottom, left, and right ends of the battery module 400, further ensuring the stability of the battery module 400.

[0145] It should be noted that the third fastener 116 can be a bolt connection assembly, riveting assembly, snap-fit ​​assembly, welding assembly, magnetic connection assembly, etc.

[0146] It should be noted that, in order to facilitate the connection of the third fixing member 116 to the bottom of the battery module 400, a window is provided at the front end of the battery module 400. The window connects to the bottom of the battery module 400, so that workers or robotic arms can easily reach into the window to connect the third fixing member 116 to the bottom of the battery module 400.

[0147] In some embodiments, reference is made to Figure 15 and Figure 16 As shown, the third fastener 116 is connected to the side of the battery module 400 away from the first support beam 113.

[0148] In this embodiment, since the second fixing member 115 is connected to the side of the battery module 400 adjacent to the first support beam 113, and the third fixing member 116 is connected to the side of the battery module 400 away from the first support beam 113, that is, the second fixing member 115 and the third fixing member 116 are arranged diagonally opposite each other. The second fixing member 115 and the third fixing member 116 achieve diagonal fixation of the battery module 400 in the vertical direction. With fewer fixing members, the upper and lower surfaces of the battery module 400 can be fixed. Therefore, it is not necessary to set a fixing member directly below the second fixing member 115 to connect the battery module 400, nor is it necessary to set a fixing member directly above the third fixing member 116 to connect the battery module 400, thereby saving the number of fixing members.

[0149] In one possible embodiment, the first fastener 112 is threadedly connected to the battery module 400, the second fastener 115 is threadedly connected to both the battery module 400 and the first support beam 113, and the third fastener 116 is threadedly connected to the battery module 400.

[0150] It should be noted that threaded connections can include bolt connections, double-ended bolt connections, screw connections, self-locking threaded connections, etc.

[0151] In another embodiment, reference is made to Figure 2 and Figure 7 As shown, a light 900 is also provided inside the cavity 110 to facilitate the user's observation of the situation inside the cavity 110.

[0152] The second aspect of this application provides an energy storage system, including at least two battery modules 400 and an energy storage cabinet of any of the above embodiments, wherein at least two battery modules 400 are disposed in a cavity 110 and at least two battery modules 400 are disposed along a first direction.

[0153] Since each battery module 400 of the energy storage system in this embodiment is housed within the energy storage cabinet of any of the above embodiments, the energy storage cabinet includes a cabinet 100. The cabinet 100 has a cavity 110, a first opening 120, and a second opening 130. The cavity 110 can accommodate at least two battery modules 400. The cabinet 100 has a first opening 120 and a second opening 130, both of which communicate with the cavity 110. Because the first opening 120 and the second opening 130 are located on opposite sides of the cabinet 100, i.e., the energy storage system in this embodiment... The traditional cabinet 100 does not have a back panel. When using an existing energy storage cabinet to accommodate at least two battery modules 400, at least two existing energy storage cabinets are required. Since the existing energy storage cabinets have back panels, at least two back panel materials will be consumed. However, compared with using multiple existing energy storage cabinets, the energy storage system using the embodiment of this application not only reduces the number of energy storage cabinets, but also reduces the material consumption of at least two back panels. That is, when accommodating at least two battery modules 400, the energy storage system of the embodiment of this application consumes less material, and the material cost of the energy storage cabinet is lower.

[0154] It should be noted that the embodiments referred to in the specification, such as "one embodiment," "embodiment," "exemplary embodiment," and "some embodiments," may include specific features, structures, or characteristics, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0155] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "one" or "" can also be understood to convey either singular or plural usage.

[0156] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0157] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0158] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
