Description

Technical Field

[0001] This application relates to the technical field of energy storage devices, and more particularly to an energy storage system. Background Technology

[0002] Energy storage systems are systems used to store and exchange energy.

[0003] Energy storage systems typically consist of a cabinet and multiple independent chambers, each housing different components. The components in different chambers require different sealing levels, thus the cabinet needs to be designed with different sealing levels.

[0004] Typically, sealing is achieved by installing sealing strips at different cavity openings and then using the squeezing force of the cabinet door closing. However, due to some errors in the installation position and size of the sealing strips, the cabinet door may squeeze multiple sealing strips at the same time, resulting in squeezing tolerances. It is difficult to accurately control the tolerance levels between different sealing strips, which causes certain problems in the stability of the sealing structure and its design and installation. Utility Model Content

[0005] This application provides an energy storage system that makes it easier to design and manufacture the protection level of the cabinet.

[0006] This application provides an energy storage system, comprising: a cabinet including a cabinet body and a cabinet door, the cabinet body having an open receiving cavity, the cabinet door being connected to the cabinet body to cover the openness; a first sealing element disposed on the periphery of the openness, the cabinet door abutting against the first sealing element to seal the receiving cavity; a partition assembly disposed in the receiving cavity and defining a mounting cavity within the receiving cavity; and a converter module disposed in the mounting cavity, the mounting cavity having an opening facing the cabinet door; wherein the converter module includes an interconnected body and a sealing plate, the body being disposed in the mounting cavity, and the sealing plate being configured to connect with the partition assembly to seal the opening.

[0007] In this application, the cabinet door only seals the accommodating cavity. When the cabinet door is closed, it only needs to compress the first sealing element to achieve a seal. Since the cabinet door only needs to compress the first sealing element, the design, processing, and installation of the first sealing element are relatively easy to control, significantly reducing production difficulty and ensuring sealing effect. The sealing of the mounting cavity relies on the structural design of the converter module itself. Specifically, when installing the converter module, the opening is sealed by a sealing plate. Through the above solution, the sealing of the accommodating cavity and the mounting cavity are independent of each other, allowing components with different sealing requirements to be placed separately. The cabinet door does not need to compress two sealing elements simultaneously, thereby effectively reducing the difficulty of processing, design, and installation. Furthermore, the sealing levels of both can be easily adjusted according to needs, resulting in better adaptability.

[0008] As one of the optional embodiments of this application, the partition assembly includes a partition and an isolation member connected to the inner wall of the cabinet. The partition and the isolation member are arranged vertically at intervals in the receiving cavity, and an installation cavity is formed between the partition and the isolation member.

[0009] As one of the optional embodiments of this application, it further includes a flame-retardant layer, and the spacer and / or the isolation member has a cavity, with the flame-retardant layer disposed in the cavity.

[0010] In this embodiment, the flame-retardant layer prevents the spread of flames, reducing the spread of flames into the containment cavity when the converter module catches fire, minimizing the impact of temperature diffusion on other components, reducing the risk of fire, thereby improving the overall safety of the energy storage system, ensuring the temperature consistency of the energy storage system, and extending its service life.

[0011] As one of the optional embodiments of this application, the partition includes a bottom plate, a top plate, and a side plate. The bottom plate and the top plate are spaced apart in the vertical direction, and the side plate is connected between the top plate and the bottom plate. The bottom plate, the side plate, and the top plate together form a cavity.

[0012] As one of the optional embodiments of this application, the separator further includes a first reinforcing rib, which is connected between the bottom plate and the side plate.

[0013] As one of the optional embodiments of this application, the separator further includes a second reinforcing rib, which is disposed on the side of the bottom plate near the top plate.

[0014] To achieve the above technical solution, a specific structure for the separator is proposed. The first and second reinforcing ribs can effectively improve the structural strength of the separator and reduce the impact on other components when the converter module explodes, thereby improving the safety performance of the energy storage system.

[0015] As one of the optional embodiments of this application, a second seal is also included, which is disposed on the periphery of the opening and sandwiched between the cabinet and the sealing plate.

[0016] As one alternative embodiment of this application, the sealing plate is connected to the partition assembly by fastener bolts and covers the opening.

[0017] By implementing the above technical solution, the sealing plate enables detachable connection between itself and the partition component, which facilitates the installation of the energy storage system and subsequent maintenance. The second sealing component ensures the sealing level requirements of the installation cavity while enabling detachable connection.

[0018] As one of the optional embodiments of this application, the cabinet is provided with heat dissipation holes that communicate with the mounting cavity.

[0019] As one of the optional embodiments of this application, it further includes an energy storage module, wherein the separator and the accommodating cavity form an energy storage chamber, and the energy storage module is disposed in the energy storage chamber.

[0020] As one of the optional embodiments of this application, it further includes a cooling module, wherein the isolation member and the receiving cavity form a cooling chamber, and the cooling module is disposed in the cooling chamber.

[0021] One of the above technical solutions has the following advantages or beneficial effects: the cabinet door only seals the accommodating cavity. When the cabinet door is closed, it only needs to compress the first sealing element to achieve a seal. Since the cabinet door only needs to compress the first sealing element, the design, processing, and installation of the first sealing element are relatively easy to control, significantly reducing production difficulty and ensuring sealing effect. The sealing of the mounting cavity relies on the structural design of the converter module itself. Specifically, when installing the converter module, the opening is sealed by a sealing plate. Through the above solutions, the sealing of the accommodating cavity and the mounting cavity are independent of each other, allowing components with different sealing requirements to be placed separately. The cabinet door does not need to compress two sealing elements simultaneously, thereby effectively reducing the difficulty of processing, design, and installation. Furthermore, the sealing levels of both can be easily adjusted according to requirements, resulting in better adaptability. Attached Figure Description

[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 scope of protection of this application.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0040] Energy storage systems generally refer to a collection of equipment systems used to store and manage energy. Energy storage systems are typically in the form of cabinets, which house various components with different functions. Therefore, the cabinet interior is usually divided into multiple independent chambers, with different components housed in different chambers. Because the functions of the components differ, their sealing requirements also differ, necessitating different levels of protection design within the cabinet. In related technologies, sealing strips are installed around the openings of different chambers; when the cabinet door is closed, the corresponding sealing strips are compressed to create a seal.

[0041] However, closing the cabinet door requires pressing at least two sealing strips simultaneously to achieve a seal. But due to errors in the installation position and size of the sealing strips, this results in compression tolerances when the cabinet door presses against two strips simultaneously. It is difficult to accurately control the tolerance levels between different sealing strips, which causes problems with the stability of the sealing structure and its design and installation. Therefore, this application redesigns the cabinet structure to achieve a smoother and more accurate sealing protection level.

[0042] The following is in conjunction with the appendix Figure 1-5 This application will be further described below.

[0043] Reference Figure 1 , Figure 2 and Figure 3 This application provides an energy storage system, including a cabinet 1, a partition assembly 3, a converter module 7, and a first seal 2.

[0044] For cabinet 1, cabinet 1 includes a cabinet body 11 and a cabinet door 12. The cabinet body 11 is rectangular and has a length direction X and a height direction Z. The height direction Z is the vertical direction. The cabinet body 11 has an accommodating cavity 10 with an opening 10a located on one side of the cabinet body 11 in the length direction X. The cabinet door 12 is connected to the cabinet body 11 to cover the opening 10a. In some examples, the cabinet door 12 is hinged to the cabinet body 11 on the side of the opening 10a.

[0045] Regarding the first seal 2, it is disposed around the periphery of the opening 10a, and the cabinet door 12 abuts against the first seal 2 to seal the receiving cavity 10. In some examples, the first seal 2 is a silicone sealing strip, which is rectangular and surrounds the periphery of the opening 10a. When the cabinet door 12 is closed, the inner wall of the cabinet door 12 presses against the first seal 2 to achieve a seal for the receiving cavity 10.

[0046] Regarding the partition assembly 3, the partition assembly 3 is disposed in the receiving cavity 10 and defines a mounting cavity 101 within the receiving cavity 10. The converter module 7 is disposed in the mounting cavity 101, which has an opening 101a facing the cabinet door 12; wherein, the converter module 7 includes a body 71 and a sealing plate 72 connected to each other, the body 71 is disposed in the mounting cavity 101, and the sealing plate 72 is connected to the end of the body 71 near the opening 101a, and the sealing plate 72 is connected to the partition assembly 3 to seal the opening 101a.

[0047] In this application, the cabinet door 12 only seals the accommodating cavity 10. When the cabinet door 12 is closed, it only needs to compress the first sealing element 2 to seal the accommodating cavity 10. Since the cabinet door 12 only needs to compress the first sealing element 2, the design, processing, and installation of the first sealing element 2 are relatively easy to control, significantly reducing production difficulty and ensuring sealing effect. The sealing of the mounting cavity 101 is achieved by the structural design of the converter module 7 itself. Specifically, when installing the converter module 7, the opening 101a is sealed by the sealing plate 72. Through the above scheme, the sealing of the accommodating cavity 10 and the mounting cavity 101 are independent of each other, allowing components with different sealing requirements to be placed separately. The cabinet door 12 does not need to compress two sealing elements simultaneously, thereby effectively reducing the difficulty of processing design and installation. Furthermore, the sealing levels of both can be easily adjusted according to requirements, resulting in better adaptability.

[0048] Reference Figure 3 and Figure 4 As one of the optional embodiments of this application, the partition component 3 includes a partition 31 and an isolation component 32 connected to the inner wall of the cabinet 11. The partition 31 and the isolation component 32 are arranged vertically at intervals in the accommodating cavity 10, and an installation cavity 101 is formed between the partition 31 and the isolation component 32.

[0049] The partition component 3 is disposed in the accommodating cavity 10 and defines the mounting cavity 101 within the accommodating cavity 10. This can be understood as follows: the periphery of the partition 31 is connected to the periphery of the inner wall of the cabinet 11, the periphery of the partition 32 is connected to the periphery of the inner wall of the cabinet 11, the partition component 3 cooperates with the cabinet 11 to define an independent mounting cavity 101, and the mounting cavity 101 has an opening 101a facing the cabinet door 12.

[0050] When installing the converter module 7, the main body 71 is placed into the mounting cavity 101, and then the sealing plate 72 is installed on the opening 101a to completely isolate the mounting cavity 101 from the receiving cavity 10, thereby achieving protection with different sealing levels. The sealing level of the mounting cavity 101 depends on the sealing degree between the sealing plate 72 and the opening 101a. At this time, the cabinet door 12 does not participate in the sealing of the mounting cavity 101; only the sealing of the entire receiving cavity 10 needs to be considered. Therefore, in some examples, only the first sealing element 2 is needed to achieve the sealing of the entire receiving cavity 10, thereby reducing the difficulty of processing design and installation.

[0051] In some examples, more specifically, the accommodating cavity 10 is further subdivided in addition to the mounting cavity 101. Optionally, for example, a spacer 3a is provided within the accommodating cavity 10. The spacer 3a is positioned above the partition 31 in the vertical direction. The partition 31 and spacer 3a cooperate to define an energy storage chamber 102 within the accommodating cavity 10. The spacer 3a cooperates with the top wall of the cabinet 11 to define an air-cooled chamber 104. The partition 32 cooperates with the bottom wall of the cabinet 11 to define a cooling chamber 103. Correspondingly, the energy storage system also includes an energy storage module 92, an air cooler 94, and a cooling module 93. The energy storage module 92 is disposed in the energy storage chamber 102, the air cooler 94 is disposed in the air-cooled chamber 104, and the cooling module 93 is disposed in the cooling chamber 103.

[0052] It should be noted that the above division of the accommodating cavity 10 is only an optional embodiment. In some other optional embodiments, it is not excluded that the accommodating cavity 10 may have other structural divisions and accommodate other different components.

[0053] The details of the separator component 3 will continue.

[0054] It is understood that at least one of the partition 31 and the isolation member 32 has a cavity 30. Optionally, only the partition 31 may have a cavity 30 and be filled with a flame-retardant layer 4, or only the isolation member 31 may have a cavity 30 and be filled with a flame-retardant layer 4, or both the partition 31 and the isolation member 32 may have a cavity 30 and be filled with a flame-retardant layer 4.

[0055] Reference Figure 3 and Figure 4 As one optional embodiment of this application, it further includes a flame-retardant layer 4, and a cavity 30 is formed in the separator 31 and / or the isolation member 32, with the flame-retardant layer 4 disposed within the cavity 30. In some examples, the flame-retardant layer 4 is configured as rock wool filled within the cavity 30.

[0056] In this embodiment, the flame-retardant layer 4 prevents the spread of flames. When the converter module 7 catches fire, it can reduce the spread of flames to the accommodating cavity 10, reduce the impact of temperature diffusion on other components, reduce the risk of fire, thereby improving the overall safety of the energy storage system, ensuring the temperature consistency of the energy storage system, and extending its service life.

[0057] Whether or not the separator 31 and the isolation member 32 are equipped with cavities 30 and flame-retardant layers 4 depends on the area adjacent to the separator 31 or the isolation member 32. For example, if important and precision components are stored in the area adjacent to the separator 31, consider creating a cavity 30 within the separator 31 and filling it with a flame-retardant layer 4. This can prevent the impact on the components in the adjacent area in the event of a fire in the converter module 7. The above design considerations can also serve as design requirements for whether or not to include cavities 30 and flame-retardant layers 4 within the isolation member 32.

[0058] For example, in some alternative examples, the adjacent area of ​​the separator 31 is the energy storage chamber 102 for storing the energy storage module 92, while the adjacent area of ​​the isolation member 32 is the cooling chamber 104 for storing the air cooler 94. Therefore, considering the importance of the device and the cost of processing, the cavity 30 and the flame retardant layer 4 are not provided in the isolation member 32.

[0059] As one optional embodiment of this application, the partition 31 includes a bottom plate 311, a top plate 312, and a side plate 313. The bottom plate 311 and the top plate 312 are spaced apart in the vertical direction, and the side plate 313 is connected between the top plate 312 and the bottom plate 311. The bottom plate 311, the side plate 313, and the top plate 312 together form a cavity 30. In some examples, the side plate 313, the top plate 312, and the bottom plate 311 are connected by welding.

[0060] Reference Figure 3 and Figure 5 As one optional embodiment of this application, the separator 31 further includes a first reinforcing rib 314 and a second reinforcing rib 315. The first reinforcing rib 314 is connected between the bottom plate 311 and the side plate 313, and multiple first reinforcing ribs 314 are provided, which are spaced apart along the width direction of the bottom plate 311. The second reinforcing rib 315 is provided on one side of the bottom plate 311 near the top plate 312, and multiple second reinforcing ribs 315 are spaced apart along the length direction X.

[0061] To achieve the above technical solution, a specific structure of the separator 31 is proposed. The first reinforcing rib 314 and the second reinforcing rib 315 can effectively improve the structural strength of the separator 31, reduce the impact of the converter module 7 on other components when it explodes, and thus improve the safety performance of the energy storage system.

[0062] In some examples, the partition 32 is plate-shaped and welded to the inner wall of the cabinet 11. It is understood that when the partition 32 requires an internal cavity 30 and is filled with a flame-retardant layer 4, the structural design of the partition 32 can be consistent with that of the separator 31. Alternatively, in some optional examples, the partition 32 may have a different structure from the separator 31; for example, the partition 32 may be injection molded, directly forming the cavity 30 inside. The above structures are simple and clear to understand, therefore no corresponding illustrations are provided.

[0063] As one optional embodiment of this application, a second seal 5 is also included, which is disposed around the periphery of the opening 101a and sandwiched between the cabinet 11 and the sealing plate 72. In some optional examples, the second seal 5 is a self-adhesive silicone sealing strip.

[0064] As one optional embodiment of this application, the sealing plate 72 is detachably connected to the partition assembly 3. In some examples, the sealing plate 72 is bolted to the partition assembly 3 by fasteners 6 and covers the opening 101a. The fasteners 6 pass through the sealing plate 72 and the second seal 5 and are finally bolted to the partition assembly 3. The top and bottom of the sealing plate 72 are connected to the partition 31 and the isolator 32, respectively. Optionally, the upper portion of the sealing plate 72 is connected to the side plate 313 of the partition 31, the isolator 32 has a bent edge, and the lower portion of the sealing plate 72 is bolted to the bent edge of the isolator 32.

[0065] Understandably, the detachable connection structure of the sealing plate 72 can also be in other forms. For example, optionally, the sealing plate 72 can be detachably connected to the partition component 3 via a snap-fit ​​structure. Alternatively, the sealing plate 72 can be detachably connected to the partition component 3 via a combination of snap-fit ​​and fastener 6.

[0066] It should be noted that the sealing plate 72 can also be connected to the partition assembly 3 in a non-detachable manner. For example, the sealing plate 72 can be welded or glued to the partition assembly 72.

[0067] To achieve the above technical solution, the sealing plate 72 can be detached from the partition component 3, which facilitates the installation of the energy storage system and subsequent maintenance. The second sealing element 5 ensures the sealing level requirements of the installation cavity 101 while achieving a detachable connection.

[0068] As one optional embodiment of this application, the cabinet 1 is provided with a heat dissipation hole 8 communicating with the mounting cavity 101. In some optional examples, the heat dissipation hole 8 can also be formed by opening a hole on one side of the cabinet 1 away from the opening, and then installing a perforated grille, in which case the perforated holes of the perforated grille form the heat dissipation hole 8.

[0069] The above description is only a partial implementation of the embodiments of this application and is not intended to limit the application in any way. The protection scope of the embodiments of this application is not limited thereto. Any simple modifications, equivalent changes and alterations that can be easily conceived by those skilled in the art within the technical scope disclosed in the embodiments of this application should be included within the protection scope of the embodiments of this application.
