Description

Technical Field

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

[0002] With the continuous development of battery technology, energy storage technology has also developed accordingly. In modern energy storage systems, to make products more competitive, energy storage cabinets are usually designed to protect the batteries and ensure system safety. Typically, batteries are integrated and packaged in the energy storage cabinet in a step-by-step manner to achieve modularity and standardization.

[0003] However, tiered integration and encapsulation increase material and manufacturing costs. Furthermore, existing energy storage cabinets generally have low protection ratings, typically IP55 or lower. This level of protection may not provide sufficient protection under harsh environmental conditions, leading to condensation buildup inside the cabinet. This condensation not only affects the performance of the batteries within the cabinet but can also cause electrical safety hazards such as short circuits or corrosion. Utility Model Content

[0004] This application provides an energy storage cabinet and energy storage device that can improve sealing performance and structural stability, reduce condensation formation, and thus improve the safety and reliability of the system. At the same time, it meets the requirements for optimized cabinet design, thereby reducing the overall cost of the system.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On the one hand, this application provides an energy storage cabinet, comprising:

[0007] The cabinet has an internal cavity for housing the battery module.

[0008] Cabinet door, which is rotatably mounted on the cabinet body, is used to close the opening of the cavity;

[0009] A sealing assembly, comprising a first sealing strip, the first sealing strip being disposed on the side of the cabinet facing the cabinet door and surrounding the cavity;

[0010] The locking assembly includes a first locking point, a second locking point, and a locking rod. The first locking point and the second locking point are both located on the side of the cabinet door facing the cavity. The first locking point is opposite to the side wall of the cavity in a first direction, and the second locking point is opposite to the side wall of the cavity in a second direction. The locking rod is used to connect the first locking point and the second locking point so that the first locking point and the second locking point cooperate to lock the cabinet door to the cabinet body and seal the first sealing strip between the cabinet body and the cabinet door.

[0011] The first direction and the second direction are perpendicular to each other.

[0012] In one possible implementation, the cabinet includes:

[0013] The base is used to support the battery module;

[0014] The frame connects to the base;

[0015] The first plate is connected to the frame and forms a cavity with the base.

[0016] In one possible implementation, the energy storage cabinet further includes a second plate, the sealing assembly further includes a second sealing strip, the cabinet further includes a sealing frame, the sealing frame is connected to the frame and surrounds the opening of the cavity, the second sealing strip is disposed on the side of the sealing frame facing the opening of the cavity, and the second plate is fixedly connected to the sealing frame by fasteners to seal the second sealing strip between the sealing frame and the second plate.

[0017] In one possible implementation, the locking assembly includes at least two first locking points along a second direction, with the at least two first locking points respectively located on opposite sides of the cabinet door.

[0018] In one possible implementation, the locking assembly includes a plurality of second locking points, which are spaced apart on the cabinet door along a second direction.

[0019] In one possible implementation, the locking assembly also includes a lock head, which is rotatably disposed on the side of the cabinet door away from the cavity. The lock head is connected to a locking rod to drive the locking rod to move.

[0020] In one possible implementation, the first locking point includes a first rotating shaft and a first locking tongue. The first rotating shaft is rotatably mounted on the cabinet door, the first locking tongue is connected to the first rotating shaft, and the locking rod is connected to the first rotating shaft to drive the first locking tongue to rotate and lock the cabinet door to the cabinet body.

[0021] In one possible implementation, the second locking point includes a second pivot and a second latch. The second pivot is rotatably mounted on the cabinet door, the second latch is connected to the second pivot, and the locking rod is connected to the second pivot to drive the second latch to rotate and lock the cabinet door to the cabinet body.

[0022] In one possible implementation, the inner wall of the cavity is provided with a thermal insulation layer.

[0023] On the other hand, this application provides an energy storage device, including a battery module and the aforementioned energy storage cabinet, wherein the battery module is disposed in the cavity.

[0024] The energy storage cabinet and energy storage equipment provided in this application feature a cavity design specifically for housing battery modules. The absence of a battery box effectively utilizes internal space, reducing costs and improving storage efficiency. A first sealing strip surrounds the cavity, and first and second locking points are provided on the cabinet door, ensuring locking points are present in both the first and second directions. A locking rod engages the first and second locking points, increasing the compression of the first sealing strip and achieving a more ideal compression effect. This improves the sealing performance of the energy storage cabinet, preventing dust and moisture from entering the cavity and protecting the internal battery modules and electrical components from external environmental influences. Furthermore, the locking points in both directions provide a more robust locking mechanism, enhancing the door's fixation, improving the structural stability of the energy storage cabinet, reducing the risk of accidental opening, and enhancing overall safety.

Detailed Implementation

[0035] 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.

[0036] With the continuous development of battery technology, energy storage technology has also developed accordingly. Modern energy storage systems typically employ a design architecture that integrates cells into modules, modules into battery boxes, and battery boxes into clusters in a hierarchical manner. While this design achieves modularity and standardization to some extent, it also presents the challenge of significantly reducing system costs. Each level of integration and packaging increases material and manufacturing costs.

[0037] Furthermore, existing energy storage cabinets generally have low protection ratings, typically IP55 or lower. This level of protection may not provide sufficient protection under harsh environmental conditions, leading to condensation buildup inside the cabinet. This condensation not only affects the performance of the battery modules but can also cause electrical safety hazards such as short circuits or corrosion.

[0038] In order to overcome the shortcomings of the existing technology, after repeated thinking and verification, the inventors discovered that if the battery modules are directly placed into the cabinet to form a cluster without a battery box design, the cost can be reduced. Furthermore, by setting locking points in both the length and width of the cabinet, the sealing strip can achieve an ideal compression, thereby improving the protection of the cabinet, preventing dust and moisture from entering the cavity, and protecting the internal battery modules and electrical components from the influence of the external environment.

[0039] In view of this, this application provides an energy storage cabinet, comprising:

[0040] The cabinet has an internal cavity for housing the battery module.

[0041] Cabinet door, which is rotatably mounted on the cabinet body, is used to close the opening of the cavity;

[0042] A sealing assembly, comprising a first sealing strip, the first sealing strip being disposed on the side of the cabinet facing the cabinet door and surrounding the cavity;

[0043] The locking assembly includes a first locking point, a second locking point, and a locking rod. The first locking point and the second locking point are both located on the side of the cabinet door facing the cavity. The first locking point is opposite to the side wall of the cavity in a first direction, and the second locking point is opposite to the side wall of the cavity in a second direction. The locking rod is used to connect the first locking point and the second locking point so that the first locking point and the second locking point cooperate to lock the cabinet door to the cabinet body, thereby sealing the first sealing strip between the cabinet body and the cabinet door.

[0044] The cavity is specifically designed to house battery modules, eliminating the need for a battery box and effectively utilizing internal space to reduce costs and improve the storage efficiency of the energy storage cabinet. A first sealing strip surrounds the cavity, and first and second locking points are located on the cabinet door, ensuring locking points in both the first and second directions. A locking rod engages the first and second locking points, increasing the compression of the first sealing strip for a more effective seal. This enhances the cabinet's sealing performance, preventing dust and moisture from entering and protecting the internal battery modules and electrical components from external environmental influences. Furthermore, the dual-directional locking mechanism provides a more robust locking mechanism, strengthening the door's fixation, improving the cabinet's structural stability, reducing the risk of accidental opening, and enhancing overall safety.

[0045] 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.

[0046] The following sections will provide a detailed description of the specific structure of the energy storage cabinet and various possible implementation methods.

[0048] like Figure 1 As shown in the embodiment of this application, the energy storage cabinet 100 is used in an energy storage device. The energy storage cabinet 100 is used to store the battery modules in the energy storage device, thereby improving the safety and reliability of the energy storage device.

[0049] The energy storage cabinet 100 includes a cabinet body 10, a cabinet door 20, a sealing component 30, and a locking component 40. For example... Figure 2 As shown, a cavity 101 is formed inside the cabinet 10. The cavity 101 is used to house the battery module. A cabinet door 20 is rotatably mounted on the cabinet 10. The cabinet door 20 is used to close the opening of the cavity 101. A sealing assembly 30 is used to cooperate with a locking assembly 40 to seal the opening of the cavity 101.

[0050] The cavity 101 is designed specifically for housing battery modules. The battery box-less design can effectively utilize the internal space, thereby reducing costs and improving the storage efficiency of the energy storage cabinet 100.

[0051] Specifically, the sealing assembly 30 includes a first sealing strip 31. The first sealing strip 31 is disposed on the side of the cabinet body 10 facing the cabinet door 20 and surrounds the cavity 101. The locking assembly 40 is used to lock the cabinet door 20 onto the cabinet body 10, so that the cabinet door 20 closes the opening of the cavity 101, and compresses the first sealing strip 31, so that the first sealing strip 31 seals the gap between the cabinet body 10 and the cabinet door 20.

[0052] like Figure 3 As shown, the locking assembly 40 includes a first locking point 41, a second locking point 42, and a locking rod 43. Both the first locking point 41 and the second locking point 42 are located on the side of the cabinet door 20 facing the cavity 101. The first locking point 41 is opposite to the side wall of the cavity 101 in a first direction. The second locking point 42 is opposite to the side wall of the cavity 101 in a second direction. The locking rod 43 connects the first locking point 41 and the second locking point 42.

[0053] The first direction and the second direction are perpendicular to each other.

[0054] It should be noted that the terms "parallel," "perpendicular," and "equal" include the described situation and situations that are similar to the described situation, within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, within 15°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, within 15°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, the difference between the two equals being less than or equal to 15% of either one. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] In one possible implementation, the first direction is horizontal, and the second direction is vertical. The first direction and the second direction are perpendicular to each other.

[0056] The locking rod 43 is used to engage the first locking point 41 with the second locking point 42, thereby locking the cabinet door 20 and sealing the first sealing strip 31 between the cabinet body 10 and the cabinet door 20.

[0057] A first sealing strip 31 surrounds the cavity 101, and a first locking point 41 and a second locking point 42 are provided on the cabinet door 20, ensuring that locking points are arranged in both the first and second directions of the cavity 101. The locking rod 43 engages the first locking point 41 and the second locking point 42, compressing the first sealing strip 31 in both horizontal and vertical directions. This increases the compression amount, achieving a more ideal compression effect, improving the sealing performance of the energy storage cabinet 100, preventing dust and moisture from entering the cavity 101, protecting the internal battery modules and electrical components from external environmental influences, effectively enhancing the protection level of the energy storage cabinet 100, reducing condensation formation, and thus improving the safety and reliability of the system. Furthermore, the locking points in both directions provide a more robust locking mechanism, enhancing the fixation of the cabinet door 20, improving the structural stability of the energy storage cabinet 100, reducing the risk of accidental opening, and improving overall safety.

[0058] Meanwhile, the high-protection-level energy storage cabinet 100 can optimize the internal design of the cabinet while ensuring internal electrical safety. For example, it can eliminate the battery box and allow the battery modules to form battery clusters directly in the cabinet, thereby reducing the overall cost of the system to a certain extent.

[0059] In one possible implementation, the cabinet 10 includes a base 11, a frame 12, and a first plate 13. The base 11 is used to support the battery module. The frame 12 is connected to the base 11. The first plate 13 is connected to the frame 12. The first plate 13 and the base 11 together form a cavity 101.

[0060] The combination of the base 11, frame 12, and first plate 13 provides a robust structure. The base 11 supports the battery module, ensuring its stable placement, while the connection between the frame 12 and the base 11 enhances the overall rigidity and stability. The cavity 101 formed by the base 11, frame 12, and first plate 13 provides a dedicated space for placing the battery module, optimizing the utilization of internal space and ensuring the safe and efficient operation of the battery module. Through the enclosed design of the first plate 13, the cavity 101 effectively protects the internal battery module from external environmental influences such as dust and moisture, extending the battery's lifespan.

[0061] The connection between frame 12 and the first panel 13 gives cabinet 10 modular characteristics, facilitating assembly and disassembly, transportation, and on-site installation, thus reducing construction difficulty and time costs. It allows the size and shape of cabinet 10 to be adjusted to accommodate different specifications and quantities of battery modules, offering high flexibility and adaptability. The modular design not only facilitates installation but also makes subsequent maintenance and repair more convenient, reducing operating and maintenance costs.

[0062] In one possible implementation, the first plate 13 and the frame 12 are an integral structure, which simplifies the assembly process and improves the sealing effect.

[0063] In one possible implementation, the first plate 13 is welded to the frame 12, thereby improving the connection and sealing effect.

[0064] In one possible implementation, the energy storage cabinet 100 also includes a hinge assembly 50 that connects the cabinet door 20 to the cabinet body 10.

[0065] The hinge assembly 50 allows the cabinet door 20 to open and close smoothly, providing a seamless operating experience and reducing resistance and noise when opening and closing the cabinet door 20. The hinge assembly 50 provides a stable fulcrum, ensuring the cabinet door 20 remains stable during opening and closing, reducing deformation or damage caused by uneven stress. The hinge assembly 50 is designed for easy inspection and lubrication, simplifying routine maintenance and reducing maintenance costs. The optimized design of the hinge assembly 50 maximizes the use of the opening space in the cabinet 10, improving the space utilization rate of the energy storage cabinet 100.

[0066] like Figure 4As shown, in one possible implementation, the locking assembly 40 includes at least two first locking points 41. Along the second direction, at least two first locking points 41 are respectively located on opposite sides of the cabinet door 20. That is, at least one first locking point 41 exists on each of the upper and lower side walls of the cavity 101.

[0067] By setting first locking points 41 on both sides in the second direction, the cabinet door 20 can fit more tightly against the cabinet body 10, ensuring effective compression of the first sealing strip 31, thereby enhancing the sealing performance and preventing dust and moisture from entering the cavity 101. The setting of multiple first locking points 41 ensures that the cabinet door 20 can be evenly locked when closed, improving the locking effect and preventing the cabinet door 20 from loosening or being accidentally opened. Multiple first locking points 41 provide additional support, enhancing the connection stability between the cabinet door 20 and the cabinet body 10, and reducing the risk of structural damage due to external impacts or vibrations.

[0068] In one possible implementation, the cabinet door 20 is provided with a first locking point 41 on each of the upper and lower sides in the first direction.

[0069] In one possible implementation, the locking assembly 40 includes a plurality of second locking points 42, which are spaced apart on the cabinet door 20 along a second direction.

[0070] The multiple second locking points 42 ensure that locking force can be applied to the cabinet door 20 at multiple positions when closed, improving the overall locking strength and preventing the cabinet door 20 from loosening or accidentally opening. The spaced arrangement of the second locking points 42 allows the cabinet door 20 to fit more evenly against the cabinet body 10, ensuring effective compression of the first sealing strip 31, thereby enhancing the sealing effect and preventing dust and moisture from entering the cavity 101. The spaced arrangement of the second locking points 42 along the second direction also ensures that the cabinet door 20 is subjected to uniform force when locked, reducing deformation or damage caused by local stress concentration and improving the durability of the cabinet door 20.

[0071] Multiple second locking points 42 provide more even support and fixation, enhancing the connection stability between the cabinet door 20 and the cabinet body 10 and reducing the risk of structural damage due to external impacts or vibrations.

[0072] In one possible implementation, the cabinet door 20 has five second locking points 42 spaced apart on the side away from the hinge assembly 50.

[0073] Understandably, the number of the first locking point 41 and the second locking point 42 can be increased or decreased according to the width and height of the cabinet door 20.

[0074] In one possible implementation, the locking assembly 40 further includes a lock head 44. The lock head 44 is rotatably disposed on the side of the cabinet door 20 opposite to the cavity 101. The lock head 44 is connected to the locking rod 43 to drive the locking rod 43 to move. That is, by rotating the lock head 44, the first locking point 41 and the second locking point 42 are driven to rotate, thereby locking the cabinet door 20 onto the cabinet body 10.

[0075] When the cabinet door 20 is closed, the rotating lock head 44, through the locking rod 43, actuates the first locking point 41 and the second locking point 42 in the vertical and first directions, causing the cabinet door 20 to compress the first sealing strip 31, thereby achieving a sealing and protective effect.

[0076] The rotatable design of the lock head 44 allows users to easily operate the locking and unlocking functions. Rotating the lock head 44 moves the locking lever 43, locking or unlocking the cabinet door 20, simplifying the operation process. The connection between the lock head 44 and the locking lever 43 ensures the overall coordination of the locking assembly 40, enhances the locking effect of the cabinet door 20, reduces the risk of accidental opening, and improves the safety of the energy storage cabinet 100. The lock head 44 is located on the side of the cabinet door 20 away from the cavity 101, without occupying internal space of the cavity 101, maintaining the compactness of the cabinet 10 and maximizing the utilization of internal space. Since the lock head 44 is located on the outside of the cabinet door 20, it is easy to inspect and maintain, reducing the complexity and time cost of maintenance.

[0077] In one possible implementation, the first locking point 41 includes a first rotating shaft 411 and a first locking tongue 412. The first rotating shaft 411 is rotatably mounted on the cabinet door 20. The first locking tongue 412 is connected to the first rotating shaft 411. The locking rod 43 is connected to the first rotating shaft 411 to drive the first locking tongue 412 to rotate, thereby locking the cabinet door 20 onto the cabinet body 10.

[0078] The first locking tongue 412 is locked by the rotation of the first rotating shaft 411, ensuring that the cabinet door 20 is securely locked to the cabinet body 10, providing a stronger locking effect and preventing the cabinet door 20 from loosening or being accidentally opened. The connection between the locking rod 43 and the first rotating shaft 411 allows the user to control the opening and closing of the first locking tongue 412 with a simple rotation action, making the operation flexible and convenient and improving the user experience. Because the locking mechanism is simple and intuitive in design, it is easy to inspect and maintain, reducing the complexity and time cost of maintenance.

[0079] The design of the first pivot 411 and the first locking tongue 412 typically uses robust materials that can withstand significant mechanical stress, thereby enhancing the structural reliability and durability of the locking assembly 40.

[0080] In one possible implementation, the second locking point 42 includes a second pivot 421 and a second latch 422. The second pivot 421 is rotatably mounted on the cabinet door 20. The second latch 422 is connected to the second pivot 421. The locking rod 43 is connected to the second pivot 421 to drive the second latch 422 to rotate, thereby locking the cabinet door 20 onto the cabinet body 10.

[0081] The second locking tongue 422 is locked by rotating the second pivot 421, ensuring that the cabinet door 20 is securely locked to the cabinet body 10, providing a stronger locking effect and preventing the cabinet door 20 from loosening or being accidentally opened. The connection between the locking rod 43 and the second pivot 421 allows the user to control the opening and closing of the second locking tongue 422 with a simple rotation action, making the operation flexible and convenient and improving the user experience. Because the locking mechanism is simple and intuitive in design, it is easy to inspect and maintain, reducing the complexity and time cost of maintenance.

[0082] The design of the second pivot 421 and the second locking tongue 422 typically uses robust materials that can withstand greater mechanical stress, enhancing the structural reliability and durability of the locking assembly 40.

[0083] The first rotating shaft 411 and the second rotating shaft 421 are parallel to each other, meaning their axial directions are parallel, indicating that the first rotating shaft 411 and the second rotating shaft 421 extend in the same direction along their respective axes, but they are located at different positions on the cabinet door 20. The first locking point 41 and the second locking point 42 rotate about a direction perpendicular to the plane of the cabinet door 20. The first locking tongue 412 and the second locking tongue 422 are perpendicular to each other, which can clamp the first sealing strip 31 in two directions to achieve a seal.

[0084] The first locking tongue 412 and the second locking tongue 422 being perpendicular to each other can be that the first locking tongue 412 and the second locking tongue 422 are perpendicular to each other during the opening, closing and locking processes, or they can be perpendicular to each other only when closing the door.

[0085] like Figure 5 As shown, in one possible implementation, the energy storage cabinet 100 further includes a second plate 60. The sealing assembly 30 further includes a second sealing strip 32. The cabinet 10 also includes a sealing frame 14. The sealing frame 14 is connected to the frame 12 and surrounds the opening of the cavity 101. The second sealing strip 32 is disposed on the side of the sealing frame 14 facing the opening of the cavity 101. The second plate 60 is fixedly connected to the sealing frame 14 by fasteners 61 to seal the second sealing strip 32 between the sealing frame 14 and the second plate 60.

[0086] Specifically, the sealing frame 14 is connected to the side wall of the cavity 101 and is positioned close to the opening of the cavity 101. The battery module is located on the side of the sealing frame 14 opposite to the opening of the cavity 101. The second sealing strip 32 provides a second layer of protection.

[0087] The design of the second plate 60 and the second sealing strip 32 provides double sealing protection for the energy storage cabinet 100. The second sealing strip 32, located between the sealing frame 14 and the second plate 60, further enhances the sealing performance of the cabinet 10, preventing dust and moisture from entering the cavity 101. This double-sealing structure not only improves the protection level, enabling the system to reach IP66 or even higher protection levels, but also reduces the risk of internal condensation, minimizing electrical safety hazards such as short circuits or corrosion, ensuring the safe operation of the battery modules, and helping to extend the service life of the internal battery modules and other components, reducing the frequency of replacement and maintenance. The connection between the sealing frame 14 and the frame 12, as well as the fixing design of the second plate 60, enhances the overall structural stability of the cabinet 10, providing additional support and protection. The second plate 60 is fixed by fasteners 61, facilitating disassembly and installation, and enabling convenient inspection and maintenance of the interior of the cavity 101, thus improving operational efficiency.

[0088] In one possible implementation, the first sealing strip 31 is a sealing rubber strip.

[0089] like Figure 6 As shown, in one possible implementation, the frame 12 has a flange at the opening of the cavity 101, and the first sealing strip 31 is connected to the flange.

[0090] In one possible implementation, the second sealing strip 32 is a silicone strip.

[0091] like Figure 7 As shown, in one possible implementation, the fastener 61 can be a screw, bolt, etc. The sealing frame 14 and the second plate 60 are respectively provided with threaded holes, thereby connecting the sealing frame 14 and the second plate 60 by fastener 61.

[0092] In one possible implementation, fasteners 61 are evenly distributed around the circumference of the second plate 60, thereby improving the compression effect on the second sealing strip 32.

[0093] In one possible implementation, the cabinet 10 also includes a reinforcing beam 15. The reinforcing beam 15 is connected to the base 11 or the frame 12.

[0094] The addition of reinforcing beam 15 significantly improves the overall structural strength and rigidity of cabinet 10, enhancing its resistance to external pressure and impact, and reducing the risk of deformation. Supported by the reinforcing beam 15, cabinet 10 is more stable during installation and use, reducing swaying caused by vibration or uneven ground, thus improving equipment safety. The reinforcing beam 15 helps to evenly distribute the load inside cabinet 10, especially when supporting heavy battery modules, reducing localized stress concentration and extending the service life of cabinet 10.

[0095] In one possible implementation, the cabinet door 20 is also provided with a reinforcing frame 21. The reinforcing frame 21 is connected to the side of the cabinet door 20 facing the cavity 101.

[0096] The reinforcing frame 21 increases the rigidity and strength of the cabinet door 20, enabling it to better resist external impacts and pressures and reducing the possibility of deformation. By enhancing the structural integrity of the cabinet door 20, the reinforcing frame 21 helps extend its service life and reduces wear and damage caused by frequent opening and closing. The presence of the reinforcing frame 21 helps the cabinet door 20 fit more evenly against the cabinet body 10, ensuring effective compression of the first sealing strip 31, thereby improving sealing performance and preventing dust and moisture from entering the cavity. The reinforcing frame 21 provides additional support, making the cabinet door 20 more stable during opening and closing, reducing swaying and unnecessary vibration.

[0097] In one possible implementation, the inner wall of cavity 101 is provided with a thermal insulation layer.

[0098] The thermal insulation layer helps maintain a stable temperature within the cavity 101, reducing the impact of external temperature changes on the internal battery modules, thereby improving battery performance and lifespan. By reducing heat loss, the thermal insulation layer improves the overall energy efficiency of the energy storage system and reduces energy loss due to temperature fluctuations. A stable temperature environment helps reduce the risk of battery overheating or overcooling, reducing potential safety hazards such as thermal runaway or performance degradation. The thermal insulation layer enables the energy storage cabinet to operate under a wider range of environmental conditions, including extreme hot and cold environments, enhancing the equipment's adaptability and reducing equipment failures and maintenance needs caused by temperature fluctuations, thus lowering maintenance costs. The thermal insulation layer also provides some sound insulation and vibration damping, further enhancing the performance of the energy storage cabinet 100.

[0099] Specifically, thermal insulation material can be placed on the inner wall of cavity 101 by means of adhesive bonding to reduce the temperature difference between the surface and the air, improve the thermal insulation performance of condensed objects, ensure that there is no condensation inside cavity 101, and enable the modular design of cabinet 10 without battery box.

[0100] The energy storage cabinet 100 provided in this embodiment includes a cabinet body 10, a cabinet door 20, a sealing assembly 30, and a locking assembly 40. A cavity 101 is formed inside the cabinet body 10 for housing battery modules. The cabinet door 20 is rotatably mounted on the cabinet body 10 and is used to close the opening of the cavity 101. The sealing assembly 30 includes a first sealing strip 31, which is located on the side of the cabinet body 10 facing the cabinet door 20 and surrounds the cavity 101. The locking assembly 40 includes a first locking point 41, a second locking point 42, and a locking rod 43. The first locking point 41 and the second locking point 42 are both located on the side of the cabinet door 20 facing the cavity 101. The first locking point 41 is opposite to the side wall of the cavity 101 in a first direction, and the second locking point 42 is opposite to the side wall of the cavity 101 in a second direction. The locking rod 43 is used to connect the first locking point 41 and the second locking point 42 so that the first locking point 41 and the second locking point 42 cooperate to lock the cabinet door 20 onto the cabinet 10, thereby sealing the first sealing strip 31 between the cabinet 10 and the cabinet door 20.

[0101] The cavity 101 is specifically designed to house battery modules, featuring a battery box-less design that effectively utilizes internal space, reducing costs and improving the storage efficiency of the energy storage cabinet 100. A first sealing strip 31 surrounds the cavity 101, and first locking points 41 and second locking points 42 are provided on the cabinet door 20, ensuring locking points are present in both the first and second directions of the cavity 101. The locking rod 43 engages the first locking points 41 and second locking points 42, increasing the compression of the first sealing strip 31 and achieving a more ideal compression effect. This improves the sealing performance of the energy storage cabinet 100, preventing dust and moisture from entering the cavity 101 and protecting the internal battery modules and electrical components from external environmental influences. Furthermore, the locking points in both directions provide a more robust locking mechanism, enhancing the fixation of the cabinet door 20, improving the structural stability of the energy storage cabinet 100, reducing the risk of accidental opening, and enhancing overall safety.

[0102] This application embodiment also provides an energy storage device, including a battery module and an energy storage cabinet 100. The battery module is disposed in the cavity 101.
