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

[0002] Currently, most batteries in energy storage cabinets are stacked in groups. When a single battery fails, it is difficult to disassemble it directly for maintenance. Usually, the entire battery pack needs to be moved out of the energy storage cabinet for maintenance. Due to the complex integrated structure inside the energy storage cabinet and the generally large weight of the entire battery pack, removing the entire battery pack is difficult and battery pack maintenance is inconvenient. Utility Model Content

[0003] This application provides an energy storage cabinet to at least partially solve the above-mentioned technical problems.

[0004] To achieve the above objectives, according to a first aspect of this application, an energy storage cabinet is provided, comprising:

[0005] Base;

[0006] The cabinet includes a main body and a lifting section. The main body is movably connected to the base, and the main body and the base enclose an energy storage space. The lifting section is connected to the main body.

[0012] Optionally, the base has a forklift hole on the side facing the operating port.

[0013] Optionally, the base includes a base and a support beam fixed to the base, the support beam supporting the battery pack, and the support beam having the forklift hole on the side facing the operating port.

[0014] Optionally, the cabinet further includes a protrusion, which is disposed in the energy storage space and connected to the main body, and the hoisting part passes through the main body and the protrusion respectively, and one of the protrusion and the hoisting part is detachably connected to the connecting assembly.

[0015] Optionally, the connection assembly includes a support column and a connector;

[0016] One of the support column and the hoisting part has a receiving groove, and a portion of the other is embedded in the receiving groove. A portion of the connector passes through the receiving groove and connects the support column and the hoisting part; or, one of the support column and the protrusion has a receiving groove, and a portion of the other is embedded in the receiving groove. A portion of the connector passes through the receiving groove and connects the support column and the protrusion.

[0017] According to a second aspect of this application, an energy storage system is provided, including the energy storage cabinet described above.

[0018] Beneficial Effects: The energy storage cabinet in this embodiment includes a base, a cabinet body, and connecting components. The cabinet body includes a main body and a lifting section. The main body is movably connected to the base, and the main body and the base enclose an energy storage space. The lifting section is connected to the main body and is configured for lifting by lifting equipment. The connecting components are located in the energy storage space and are respectively connected to the cabinet body and the base. At least one of the cabinet body and the base is detachably connected to the connecting components. When maintenance is required on the devices within the energy storage space, the connection between the connecting components and one of the cabinet body and the base is disconnected. The lifting section is then lifted by lifting equipment, thereby allowing the cabinet body to be lifted away from the base. This enables quick opening of the energy storage space and facilitates maintenance of the devices installed on the base. Compared to moving heavy devices such as battery packs entirely out of the energy storage space, this improves the convenience of maintaining devices within the energy storage space.

[0038] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0039] Currently, most batteries in energy storage cabinets are stacked in groups. When a single battery fails, it is difficult to disassemble it directly for maintenance. Usually, the entire battery pack needs to be moved out of the energy storage cabinet for maintenance. Due to the complex integrated structure inside the energy storage cabinet and the generally large weight of the entire battery pack, removing the entire battery pack is difficult and battery pack maintenance is inconvenient.

[0040] In view of this, refer to Figures 1 to 9 This application provides an energy storage cabinet and an energy storage system to overcome at least one of the above-mentioned technical problems.

[0041] Please refer to Figures 1 to 9 , Figure 1 This is a schematic diagram of the energy storage cabinet provided in the embodiments of this application.

Wherein, Figure 5 This is a structural schematic diagram of the connection method of the cabinet 2, the hoisting part 21, and the connecting component 3 provided in the first embodiment of this application.

[0042] It should be noted that, in conjunction with the accompanying drawings, the following embodiments of this application introduce a first direction X, a second direction Y, and a third direction Z that intersect each other. The first direction X is approximately parallel to the overall height direction of the energy storage cabinet, the second direction Y is approximately parallel to the overall length direction of the energy storage cabinet, and the third direction Z is approximately parallel to the overall width direction of the energy storage cabinet.

[0043] Reference Figure 1 and Figure 2 The energy storage cabinet includes a base 1, a cabinet body 2, and a connecting component 3.

[0044] Specifically, the cabinet 2 includes a main body 20 and a lifting section 21. The main body 20 is movably connected to the base 1, and the main body 20 and the base 1 enclose an energy storage space 23. The lifting section 21 is connected to the main body 20 and is configured for lifting by a lifting device. A connecting component 3 is disposed within the energy storage space 23 and connects the cabinet 2 and the base 1 respectively. At least one of the cabinet 2 and the base 1 is detachably connected to the connecting component 3.

[0045] When maintenance is required on the devices within the energy storage space 23, the connection between the connecting component 3 and either the cabinet 2 or the base 1 can be disconnected. The lifting device 21 can then be used to lift the cabinet 2 away from the base 1, allowing for quick opening of the energy storage space 23 and facilitating maintenance of the devices mounted on the base 1. Compared to moving a heavy device, such as the battery pack 4, entirely out of the energy storage space 23, the energy storage cabinet provided in this embodiment effectively improves the convenience of maintaining devices within the energy storage space 23. By flexibly adjusting the connecting component 3 to connect the cabinet 2 and the base 1, the cabinet 2 or the entire energy storage cabinet can be flexibly lifted and moved. Furthermore, using the connecting component 3 to connect the cabinet 2 and the base 1 respectively helps to assist the cabinet 2 in bearing the load during the lifting and moving of the entire energy storage cabinet, distributing the stress and improving the overall structural integrity.

[0046] Optionally, the hoisting part 21 can be located at the top of the cabinet 2. For example, the hoisting part 21 can be installed on the top wall 201 of the main body 20 for easy connection with hoisting equipment.

[0047] In some embodiments, refer to Figure 2 , Figure 3 and Figure 4 The main body 20 is mounted on the outside of the base 1. The main body 20 includes a main body sub-part 203 and a cabinet door 204. The main body sub-part 203 is movably connected to the base 1. At least one side of the main body sub-part 203 is provided with an operating opening 200, and the cabinet door 204 covers the operating opening 200. Figure 3As shown, the main body sub-part 203 has a perforated opening 202 on its bottom surface in the first direction X (height direction). The base 1 is positioned at the perforated opening 202. The main body sub-part 203 can directly cover the outer periphery of the base 1 through the perforated opening 202. The inner wall of the main body sub-part 203 adheres to the outer periphery of the base 1 to improve the sealing effect. Furthermore, when the entire energy storage cabinet is placed on a horizontal surface, the cabinet body 2 can adhere to the horizontal surface by its own weight, thereby achieving a seal. The cabinet body 2 completely covering the outside of the base 1 facilitates a unified appearance for the entire energy storage cabinet. The operation port 200 can be opened by opening the cabinet door 204, allowing for maintenance operations inside the energy storage cabinet from the operation port 200 side. A sealing gasket can be installed at the bottom of the cabinet body 2 to further improve the tightness of the fit to the horizontal surface and enhance the sealing effect.

[0048] In some embodiments, refer to Figure 4 The energy storage cabinet also includes a battery pack 4, which is located within the energy storage space 23. A connecting component 3 is located on the side of the battery pack 4 facing the operation port 200. By positioning the connecting component 3 on the side of the battery pack 4 facing the operation port 200, and opening the cabinet door 204 to open the operation port 200, operations can be performed at the operation port 200. This facilitates disconnecting the connection component 3 from one or both of the cabinet body 2 and the base 1. Simultaneously, the connecting component 3 provides a limiting effect on the battery pack 4, restricting its movement towards the operation port 200 and improving the stability of the battery pack 4. Alternatively, the connecting component 3 can be reconnected to one or both of the cabinet body 2 and the base 1 at the operation port 200, allowing for reassembly of the energy storage cabinet after maintenance.

[0049] In some embodiments, refer to Figure 2 and Figure 4 The main body sub-unit 203 has operation ports 200 on both opposite sides, and multiple connecting components 3 are provided. At least one connecting component 3 is provided on the side of the battery pack 4 facing each operation port 200. To evenly distribute the force of hoisting the mobile energy storage cabinet, this embodiment uses four connecting components 3 as an example. Two operation ports 200 penetrate the cabinet 2 in the second direction Y. Two connecting components 3 are provided on the side of the battery pack 4 facing each operation port 200, and adjacent connecting components 3 are spaced apart along the third direction Z. Multiple operation ports 200 facilitate access to the energy storage space 23 for device maintenance from multiple directions, reducing the need for hoisting the mobile cabinet 2. Simultaneously, multiple connecting components 3 can further distribute the hoisting force and improve the placement stability of the battery pack 4. It is understood that in other embodiments, the number of connecting components 3 can be flexibly increased according to the structural dimensions of the cabinet 2 and the overall weight of the energy storage cabinet; this will not be elaborated upon here.

[0050] In some embodiments, the connecting component 3 can be connected to the hoisting part 21 of the cabinet 2. The number of hoisting parts 21 can be the same as the number of connecting components 3. Each hoisting part 21 is connected to one connecting component 3, so that the force on each hoisting part 21 can be distributed by the connecting component 3, ensuring the stability of the structure during the overall hoisting process.

[0051] In some embodiments, the battery pack 4 is detachably connected to the connection assembly 3. It is understood that, referring to... Figure 2 and Figure 4 The battery pack 4 has a multi-layered structure stacked along its height. Each layer of the battery pack 4 can be directly connected to the connecting component 3 via methods such as bolts, further improving the overall stability of the battery pack 4. Opening the cabinet door 204 opens the operation port 200, allowing operation to be performed at the operation port 200 to separate the battery pack 4 from the connecting component 3, and to separate the connecting component 3 from one or both of the cabinet body 2 and the base 1. Then, the cabinet body 2 can be lifted off the base 1 using the lifting equipment and the lifting unit 21, enabling rapid access to the energy storage space 23 for maintenance of the battery pack 4 mounted on the base 1. Alternatively, the connecting component 3 can be reconnected to the battery pack 4 at the operation port 200, and to one or both of the cabinet body 2 and the base 1, allowing for reassembly of the energy storage cabinet after maintenance.

[0052] In some embodiments, refer to Figure 2 and Figure 4 The base 1 has a forklift hole 110 on the side facing the operating port 200. Optionally, by opening the cabinet door 204 on one side, the forklift teeth of the forklift equipment can be inserted into the forklift hole 110 through the operating port 200, and the energy storage cabinet can be moved as a whole. The base 1 can be provided with two forklift holes 110, which are arranged in the third direction Z. The spacing between the two forklift holes 110 can be adapted to the spacing of the forklift teeth of the forklift equipment, which facilitates the overall transfer of the energy storage cabinet by the forklift equipment. Alternatively, the base 1 and the battery pack 4 mounted on it can be transferred after the cabinet 2 is lifted away. In addition, the thickness of the base 1 in the first direction X can be set to be slightly thicker to meet the space required for arranging the forklift holes 110 and to ensure the overall rigidity of the structure, which meets the requirements of forklift transportation for structural rigidity.

[0053] In addition, in order to reduce the overall weight of the base 1, in some embodiments, refer to Figure 2 and Figure 4The base 1 includes a base 10 and a support beam 11 fixed to the base 10. The support beam 11 supports the battery pack 4, and a forklift hole 110 is provided on the side of the support beam 11 facing the operating port 200. The support beam 11 can be configured as a hollow structure to form the forklift hole 110. The support beam 11 can be welded to the base 10, which helps to form the forklift hole 110 while enhancing the structural strength of the base 10.

[0054] To further improve the stability of the battery pack 4 and enhance the structural strength of the base 10, multiple support beams 11 can be provided on the base 10. Two support beams 11 are spaced apart in the third direction Z, and the two support beams 11 extend along the second direction Y, respectively. Each of the two support beams 11 is provided with the forklift hole 110. Multiple support beams 11 extending along the third direction Z can also be provided between the two support beams 11 with forklift holes 110. These multiple support beams 11 can be arranged along the second direction Y and connected to the support beams 11 with forklift holes 110.

[0055] In some embodiments, refer to Figure 5 The cabinet 2 also includes a protrusion 22, which is located in the energy storage space 23 and connected to the main body 20. The hoisting part 21 passes through the main body 20 and the protrusion 22 respectively. One of the protrusion 22 and the hoisting part 21 is detachably connected to the connecting component 3.

[0056] Please combine Figure 3 and Figure 5 As shown, the main body sub-part 203 has a top wall 201 in the first direction X, and a lifting part 21 is provided on the top wall 201. In order to improve the overall structural strength of the top wall 201, in this embodiment, a protrusion 22 is also provided on the side of the top wall 201 facing the energy storage space 23. The protrusion 22 can be a welded beam structure or other structural reinforcement. Corresponding to multiple connecting components 3, multiple lifting parts 21 are also provided, and multiple lifting parts 21 correspond one-to-one with multiple connecting components 3, that is, a part of each lifting part 21 passes through the side of the top wall 201 facing the support column 30. In addition, in order to improve the deformation resistance of the top wall 201, the lifting part 21 also passes through the protrusion 22 in the height direction.

[0057] Specifically, the protrusion 22 can be the upper beam of the cabinet 2, which is fixedly connected to the top wall 201 of the main body 20, thus strengthening the top wall 201 and increasing its structural strength. The lifting part 21 is installed through the protrusion 22 and the main body 20, fully utilizing the structural strengthening effect of the protrusion 22 and reducing the risk of structural deformation and damage to the cabinet 2 during lifting. Figure 5In the illustrated embodiment, the protrusion 22 and the top wall 201 of the main body 20 are fixedly connected, and the protrusion 22 is connected to the side of the top wall 201 facing the energy storage space 23. Through holes are provided at corresponding positions of the top wall 201 and the protrusion 22. The lifting part 21 passes through the through holes and penetrates the top wall 201 and the protrusion 22. A limiting step structure is provided on the portion of the lifting part 21 located within the protrusion 22. The dimension of this limiting step structure along the third direction Z is larger than the dimension of the through hole, thereby limiting the lifting part 21 to the side of the through hole closest to the energy storage space 23, reducing the possibility of the lifting part 21 detaching from the main body 20 during lifting and ensuring structural stability. Correspondingly, a receiving groove is also provided within the protrusion 22 to accommodate the aforementioned limiting step structure.

[0058] Please combine them together Figure 6 , Figure 7 , Figure 8 The structures shown are respectively... Figure 5 Similarly, both have a protrusion 22 connecting the main body 20, and the lifting part 21 passes through the main body 20 and the protrusion 22. Furthermore, in Figure 6 , Figure 7 , Figure 8 In the illustrated embodiments, a limiting step structure may also be provided on the hoisting part 21. The hoisting part 21 is limited to the protrusion 22 by the limiting step structure, so as to further reduce the risk of the hoisting part 21 detaching from the main body part 20 during hoisting and improve the stability of the structure.

[0059] In the above embodiments, the connecting component 3 is detachably connected to the lifting part 21 (e.g., Figure 5 , Figure 6 (as shown in the embodiment), or, the connecting component 3 is detachably connected to the protrusion 22 (e.g., in the embodiment shown). Figure 7 , Figure 8 (As shown in the embodiment). Both connection methods can achieve the following: in the connected state, the lifting force is transferred to the base 1 to achieve overall hoisting; in the disassembled state, the cabinet 2 is lifted separately to detach it from the base 1, thereby facilitating the maintenance of the battery pack 4 on the base 1.

[0060] In some embodiments, please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 The connecting component 3 includes a support column 30 and a connector 31; the support column 30 is connected to one of the protrusion 22 and the hoisting part 21 through the connector 31.

[0061] Among them, such as Figure 5 and Figure 6As shown, one of the support column 30 and the hoisting part 21 has a receiving groove 300, and part of the other is embedded in the receiving groove 300. Part of the connector 31 passes through the receiving groove 300 and connects the support column 30 and the hoisting part 21.

[0062] Specifically, in Figure 5 In the illustrated embodiment, a receiving groove 300 is provided at one end of the support column 30 facing the hoisting part 21 (e.g., the top of the support column 30). The connecting member 31 can be a connecting pin. When the cabinet 2 is installed outside the base 1, each hoisting part 21 has a partial structure (e.g., the aforementioned limiting step structure) embedded in the corresponding receiving groove 300. The connection between the hoisting part 21 and the support column 30 is achieved by the connecting member 31 passing through them. It is understood that in other embodiments, the connecting member 31 can also be a bolt or other connection structure, which will not be elaborated here. In addition, optionally, the receiving groove 300 can penetrate the support column 30 along the first direction X, that is, the support column 30 is set as a hollow structure, and the top part of its hollow inner cavity can serve as the receiving groove 300 to accommodate part of the structure of the hoisting part 21.

[0063] exist Figure 6 In the illustrated embodiment, a receiving groove 300 may also be provided at one end of the lifting part 21 facing the support column 30 (for example, the bottom end of the lifting part 21), and a protrusion structure corresponding to the receiving groove 300 may be provided on the top of each support column 30. When the cabinet 2 is installed on the outside of the base 1, the protrusion structure of the support column 30 is embedded in the corresponding receiving groove 300, and the connection between the lifting part 21 and the support column 30 is achieved by the connector 31 passing through it.

[0064] like Figure 7 and Figure 8 As shown, one of the support column 30 and the protrusion 22 has a receiving groove 300, and a part of the other is embedded in the receiving groove 300. A part of the connector 31 passes through the receiving groove 300 and connects the support column 30 and the protrusion 22.

[0065] Specifically, in Figure 7 In the illustrated embodiment, a receiving groove 300 is provided at one end of the protrusion 22 facing the support column 30. The connector 31 can be a connecting pin. When the cabinet 2 is installed on the outside of the base 1, a portion of the structure of each support column 30 is embedded in the corresponding receiving groove 300. The connection between the protrusion 22 and the support column 30 is achieved by the connector 31 passing through it. Optionally, the support column 30 can be configured as a hollow structure, or it can have a clearance groove at its top. The corresponding receiving groove 300 is embedded at the top of the support column 30, and the limiting step structure of the hoisting part 21 is set at the top of the inner cavity of the support column 30 or in the clearance groove.

[0066] exist Figure 8In the illustrated embodiment, a receiving groove 300 is provided at one end of the support column 30 facing the protrusion 22. The connector 31 can be a connecting pin. When the cabinet 2 is installed on the outside of the base 1, a portion of the structure of each protrusion 22 is embedded in the corresponding receiving groove 300. The connection between the protrusion 22 and the support column 30 is achieved by the connector 31 passing through them. Optionally, the receiving groove 300 can penetrate the support column 30 along the first direction X, that is, the support column 30 is set as a hollow structure, and the top part of its hollow inner cavity can serve as the receiving groove 300 to accommodate a portion of the structure of the protrusion 22.

[0067] It should also be noted that, in one or more of the above embodiments, the support column 30 and the lifting part 21 are respectively provided with pin holes for the connector 31 to pass through, so that the connector 31 can correspondingly pass through the support column 30 and the lifting part 21. Alternatively, the support column 30 and the protrusion 22 are respectively provided with pin holes for the connector 31 to pass through, so that the connector 31 can correspondingly pass through the support column 30 and the protrusion 22. Optionally, the above-mentioned pin holes can also be set as threaded holes, and the connector 31 is set as a stud corresponding to the threaded hole, which cooperates with each other to achieve a threaded connection.

[0068] According to a second aspect of this application, an energy storage system is provided, including the aforementioned energy storage cabinet. It is understood that this energy storage system can possess all the technical features and effects of the aforementioned energy storage cabinet, which will not be elaborated upon here. For example, refer to... Figure 9 The energy storage system may include container 5, and multiple energy storage cabinets may be arranged side by side within container 5. In addition to storing battery packs 4, some energy storage cabinets may also be equipped with energy storage converters, temperature control equipment, fire-fighting equipment, etc., which will not be described in detail here.
