[0008] Optionally, the cabinet includes a first base and a first baffle. An air inlet is opened in the first base. The first baffle is disposed in the first base and is located at one end of the air inlet along the arrangement direction of multiple blades. The first baffle is bent towards the interior of the first base. A fourth air duct and a fifth air duct are formed between the first baffle and adjacent blades. The two ends of the fourth air duct are respectively connected to the fifth air duct and the exterior of the first base. The fourth air duct is spaced apart from the interior of the first base through the fifth air duct. One end of the fifth air duct is connected to the interior of the first base, and the other end is spaced apart from the exterior of the first base through the fourth air duct.
[0009] Optionally, the cabinet includes a second baffle, which is disposed on the first base and located at the end of the air inlet away from the first baffle along the arrangement direction of the multiple blades.

[0015] To achieve the above objectives, the present invention provides an energy storage system comprising a battery pack and an energy storage cabinet, wherein the battery pack is housed inside the energy storage cabinet.
[0016] The beneficial effects of this utility model are as follows:
[0017] The energy storage cabinet includes a cabinet body and multiple blades. The cabinet body has an air inlet that connects to the interior of the cabinet. Multiple blades cover the air inlet and are spaced apart within the cabinet body. Adjacent blades form a first air duct and a second air duct. One end of the first air duct connects to the interior of the cabinet body, and the other end connects to the second air duct. The end of the second air duct furthest from the first air duct connects to the exterior of the cabinet body. The first air duct and the exterior of the cabinet body are spaced apart, and the second air duct and the interior of the cabinet body are spaced apart.
[0018] In practical applications, by incorporating multiple blades and corresponding first and second air ducts, this design effectively prevents raindrops and external contaminants from entering the cabinet. Firstly, the blades directly block most raindrops, preventing them from entering the cabinet. Even if a small amount of rainwater enters the second air duct due to the splashing effect of the blades, the spacing between the second air duct and the cabinet interior prevents further water from flowing into the cabinet, thus reducing the potential damage to the battery pack and electrical equipment inside the cabinet from rainwater and other external liquids. Simultaneously, the second air duct connects to the first air duct, forming an effective ventilation path. Low-temperature external air can flow into the cabinet through both the second and first air ducts for air cooling, ensuring efficient heat dissipation within the cabinet. Therefore, this structure not only guarantees the internal temperature control performance of the cabinet but also enhances its waterproof and dustproof capabilities, ensuring the stable operation and safety of the energy storage cabinet in outdoor environments.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1 to 5 As shown, Figure 1 This is an overall schematic diagram of the energy storage device provided in this embodiment of the utility model. Figure 2 This is a front view of the energy storage cabinet provided in this embodiment of the utility model. Figure 3 This is a partial structural schematic diagram of the energy storage cabinet provided in an embodiment of this utility model.

Figure 5 This is a partial structural diagram of the unassembled filter section 103 and a partially enlarged diagram of region D provided in this embodiment of the present invention.
[0030] This utility model provides an energy storage system, including a battery pack 110 and an energy storage cabinet, wherein the battery pack 110 is assembled inside the energy storage cabinet.
[0031] Specifically, the energy storage cabinet includes a cabinet body 20 and multiple blades 30. The cabinet body 20 has an air inlet 21, which is connected to the interior of the cabinet body 20. The multiple blades 30 cover the air inlet 21 and are spaced apart in the cabinet body 20. A first air duct 40 and a second air duct 50 are formed between adjacent blades 30. In the depth direction of the cabinet body 20 (i.e., the direction perpendicular to the plane where the air inlet 21 is located), one end of the first air duct 40 is connected to the interior of the cabinet body 20, and the other end is connected to the second air duct 50. The end of the second air duct 50 away from the first air duct 40 is connected to the exterior of the cabinet body 20. The first air duct 40 and the exterior of the cabinet body 20 are spaced apart, and the second air duct 50 and the interior of the cabinet body 20 are spaced apart.
[0032] In practical applications, by setting multiple blades 30 and corresponding first air ducts 40 and second air ducts 50, this design effectively prevents raindrops and external dirt from entering the cabinet 20. Firstly, the blades 30 directly block most raindrops, preventing them from directly entering the cabinet 20. Even if a small amount of rainwater enters the second air duct 50 due to the splashing effect of the blades 30, the spacing between the second air duct 50 and the cabinet 20 prevents further water from flowing into the cabinet 20, thus reducing the potential damage of rainwater and other external liquids to the battery pack 110 and electrical equipment inside the cabinet 20. Simultaneously, the second air duct 50 is connected to the first air duct 40, forming an effective ventilation path. Low-temperature external air can flow into the cabinet 20 through the second air duct 50 and the first air duct 40 for air cooling, ensuring the heat dissipation efficiency inside the cabinet 20. Therefore, this structure not only ensures the temperature control performance inside the cabinet 20 but also enhances its waterproof and dustproof capabilities, ensuring the stable operation and safety of the energy storage cabinet in outdoor environments.
[0033] Further, see Figure 5 The blade 30 includes a first part 31, a second part 32, a third part 33 and a fourth part 34. The first part 31 is connected to the cabinet 20. The two opposite ends of the first part 31 are connected to the second part 32 and the third part 33, respectively. The second part 32 and the third part 33 extend in a direction away from the interior of the cabinet 20. The end of the third part 33 away from the first part 31 is connected to the fourth part 34. The fourth part 34 extends in a direction away from the second part 32.
[0034] A first air duct 40 is formed between the second part 32 and the third part 33 and the fourth part 34 of the adjacent blade 30. The first air duct 40 is spaced apart from the outside of the cabinet 20 through the fourth part 34. A second air duct 50 is formed between the first part 31, the second part 32, the third part 33 and the fourth part 34 of the adjacent blade 30. The second air duct 50 is spaced apart from the inside of the cabinet 20 through the first part 31. The opening of the second air duct 50 away from the inside of the cabinet 20 is set downward to reduce rainwater entering the second air duct 50 directly from the opening of the second air duct 50.
[0035] In practical applications, blade 30 includes a first part 31, a second part 32, a third part 33, and a fourth part 34. The third part 33 and the fourth part 34 are positioned outside the second air duct 50, directly blocking rainwater and external contaminants from entering the second air duct 50. Rainwater is first intercepted by the third part 33 and the fourth part 34, preventing it from entering the second air duct 50, thus protecting the equipment inside the cabinet 20 from moisture and contamination. Even if a small amount of rainwater splashes into the second air duct 50, it will be blocked by the first part 31, the second part 32, and the third part 33 and the fourth part 34 of the adjacent blade 30, preventing it from further entering the cabinet 20 through the first air duct 40. Simultaneously, the connection between the second air duct 50 and the first air duct 40 ensures that low-temperature external gases can smoothly enter the cabinet 20 through both ducts, providing effective air cooling and reducing the internal temperature of the cabinet 20. This design not only ensures the waterproof performance of the energy storage cabinet in outdoor environments, but also improves its heat dissipation efficiency, ensuring long-term stable operation of the equipment.
[0036] Further, see Figure 5 The blade 30 includes a fifth part 35, which is connected to the end of the fourth part 34 away from the third part 33. The fifth part 35 is inserted into the second air duct 50 and divides the second air duct 50 to form a first sub-air duct 51 and a second sub-air duct 52. The second air duct 50 is spaced apart by the first part 31 and the interior of the cabinet 20.
[0037] A first sub-air duct 51 is formed between the fifth part 35 and the first part 31 and the third part 33 of the adjacent blade 30. The two ends of the first sub-air duct 51 are connected to the second sub-air duct 52 and the outside of the cabinet 20, respectively. A second sub-air duct 52 is formed between the fifth part 35 and the first part 31 and the second part 32 of the adjacent blade 30. The first air duct 40 is connected to the first sub-air duct 51 through the second sub-air duct 52.
[0038] In practical applications, the air duct system of the energy storage cabinet is further optimized by adding a fifth part 35 to the blade 30 structure. The fifth part 35 divides the original second air duct 50 into a first sub-air duct 51 and a second sub-air duct 52, forming a more refined airflow channel. First, the third part 33, the fourth part 34, and the fifth part 35 together form the sidewalls of the first air duct 40 and the second sub-air duct 52 from different directions, significantly improving the rainwater isolation effect. In this way, splashed rainwater entering the first sub-air duct 51 can be effectively blocked by the sidewalls of the second sub-air duct 52, reducing the possibility of water droplets further entering the second sub-air duct 52, thereby reducing the amount of rainwater entering the first air duct 40 through the first sub-air duct 51.
[0039] Airflow sequentially enters the cabinet 20 through the first sub-air duct 51, the second sub-air duct 52, and the first air duct 40 for air cooling, ensuring excellent heat dissipation performance inside the energy storage cabinet. This not only effectively prevents rainwater and other liquids from entering the cabinet 20 but also ensures unobstructed airflow within the cabinet 20, providing a more stable and efficient heat dissipation effect. This allows the energy storage cabinet to better protect internal electrical equipment under harsh weather conditions, extend equipment lifespan, and improve overall reliability.
[0040] Further, see Figure 5 The second sub-air duct 52 is inclined relative to the first sub-air duct 51.
[0041] In practical applications, by tilting the second sub-duct 52 relative to the first sub-duct 51, the airflow resistance within the channel is increased, reducing the airflow velocity in both sub-ducts 51 and 52. Simultaneously, the distance the airflow travels through these ducts is extended, allowing more time for moisture and liquids carried in the airflow to adhere to the inner walls of the ducts. This design effectively reduces the likelihood of moisture and liquids entering the cabinet 20, thereby effectively preventing potential damage to the electrical equipment inside the cabinet 20.
[0042] In this embodiment, the angle between the first sub-air duct 51 and the second sub-air duct 52 is an acute angle, so that the first sub-air duct 51 and the second sub-air duct 52 form a V-shape, while the first air duct 40, the first sub-air duct 51 and the second sub-air duct 52 together form a Z-shaped channel.
[0043] In one embodiment, see Figure 4 and Figure 5The cabinet 20 includes a first base 22 and a first baffle 23. An air inlet 21 is opened in the first base 22. The first baffle 23 is disposed in the first base 22 and is located at one end of the air inlet 21 along the arrangement direction of the plurality of blades 30. The first baffle 23 is bent toward the interior of the first base 22. A fourth air duct 60 and a fifth air duct 70 are formed between the first baffle 23 and the adjacent blades 30. The two ends of the fourth air duct 60 are respectively connected to the fifth air duct 70 and the exterior of the first base 22. The fourth air duct 60 is spaced apart from the interior of the first base 22 through the fifth air duct 70. One end of the fifth air duct 70 is connected to the interior of the first base 22, and the other end is spaced apart from the exterior of the first base 22 through the fourth air duct 60.
[0044] In practical applications, a first baffle 23 is installed at one end of the air inlet 21 of the energy storage cabinet, and a fourth air duct 60 and a fifth air duct 70 are formed between the blades 30 and the first baffle 23. Low-temperature external airflow can sequentially enter the cabinet 20 through the fourth air duct 60 and the fifth air duct 70, effectively cooling the interior of the cabinet 20. Simultaneously, the first baffle 23 effectively blocks external rainwater and pollutants, preventing them from entering the cabinet 20. This design not only improves the air-cooling efficiency inside the cabinet 20 but also reduces the entry of moisture or pollutants, thereby increasing the service life and stability of the electrical equipment inside the cabinet 20.
[0045] Furthermore, referring to Figure 4 and Figure 5 The cabinet 20 includes a second baffle 24, which is disposed on the first base 22 and located at the end of the air inlet 21 away from the first baffle 23 along the arrangement direction of the plurality of blades 30. The second baffle 24 is bent away from the interior of the first base 22. A sixth air duct 80 and a seventh air duct 90 are formed between the second baffle 24 and the adjacent blades 30. The two ends of the sixth air duct 80 are respectively connected to the seventh air duct 90 and the exterior of the first base 22. The sixth air duct 80 is spaced apart from the interior of the first base 22 through the seventh air duct 90. One end of the seventh air duct 90 is connected to the interior of the first base 22, and the other end is spaced apart from the exterior of the first base 22 through the sixth air duct 80.
[0046] In practical applications, a second baffle 24 is installed at the end of the air inlet 21 of the energy storage cabinet away from the first baffle 23. A sixth air duct 80 and a seventh air duct 90 are formed between the blades 30 and the second baffle 24. Low-temperature external airflow can sequentially enter the cabinet 20 through the sixth and seventh air ducts 80 and 90, further enhancing the air-cooling effect inside the cabinet 20. Simultaneously, the second baffle 24 effectively blocks external rainwater and pollutants, preventing them from entering the cabinet 20. This design not only improves the heat dissipation efficiency of the cabinet 20 but also reduces the entry of moisture or pollutants, further enhancing the operational stability and service life of the electrical equipment.
[0047] In one embodiment, reference is made to Figure 1 and Figure 3 The energy storage cabinet includes a filter assembly 100, which includes a filter section 103. The filter section 103 is located inside the cabinet 20 and covers the air inlet 21.
[0048] In practical applications, by installing a filter assembly 100 inside the energy storage cabinet, with the filter section 103 covering the air inlet 21, dust, debris, and other particulate matter in the air entering the cabinet 20 through the air inlet 21 can be effectively filtered, thus preventing these pollutants from entering the cabinet 20. This design not only helps maintain clean air inside the cabinet 20 and reduces the impact of pollutants on electrical equipment, but also improves the operating efficiency and stability of the equipment inside the cabinet 20 and extends the service life of the equipment.
[0049] In this embodiment, the filtration unit 103 can be a mesh filter, a foam filter, or an activated carbon filter.
[0050] Furthermore, referring to Figure 3 and Figure 4 The filter assembly 100 includes a first fixing member 101 and a second fixing member 102. The first fixing member 101 and the second fixing member 102 are respectively disposed on the cabinet 20 and located at opposite ends of the air inlet 21. A receiving cavity 25 is formed between the first fixing member 101 and the second fixing member 102. The filter part 103 is disposed inside the receiving cavity 25. The first fixing member 101 and the second fixing member 102 are used to restrict the filter part 103.
[0051] In practical applications, by setting a first fixing member 101 and a second fixing member 102 at both ends of the air inlet 21 of the energy storage cabinet, forming a receiving cavity 25 between them, the filter section 103 can be stably accommodated. The filter section 103 is confined within the receiving cavity 25, ensuring its stable position within the cabinet 20, thereby effectively filtering the airflow entering the cabinet 20. The design of the first fixing member 101 and the second fixing member 102 makes the filter section 103 less prone to displacement or detachment, enhancing the structural stability and sealing of the filter assembly 100. This design not only improves the filtration effect but also ensures smooth airflow within the energy storage cabinet, while reducing the entry of external debris or dust, further improving the cleanliness of the internal environment of the cabinet 20 and protecting the long-term stable operation of the energy storage equipment.
[0052] Optionally, refer to Figure 4 In the direction perpendicular to the plane where the air inlet 21 is located, the thickness of the receiving cavity 25 is greater than the thickness of the filter section 103.
[0053] In practical applications, by setting the thickness of the receiving cavity 25 to be greater than the thickness of the filter section 103, the space between the filter section 103 and the cabinet 20 can be effectively increased, providing more room for the installation of the filter section 103. Especially when the filter section 103 uses foam or sponge material, the larger space provides more room for expansion, ensuring that the filter section 103 can fully expand and maintain good filtration performance. This design not only makes the filter section 103 installation more stable but also provides sufficient space for subsequent maintenance and replacement, thereby improving the ease of use of the energy storage cabinet. Furthermore, the larger space can prevent the filter section 103 from being damaged due to excessive expansion, extending its service life and ensuring air circulation and heat dissipation efficiency inside the energy storage cabinet.
[0054] Optionally, refer to Figure 6 The first fixing member 101 and / or the second fixing member 102 are provided with adjustment holes 105. The extension direction of the adjustment holes 105 is the connection direction of the first fixing member 101 and the second fixing member 102. The filter assembly 100 includes a locking member 104, which passes through the adjustment holes 105 to connect the cabinet 20. The first fixing member 101 or the second fixing member 102 can move along the extension direction of the adjustment holes 105 to adjust the distance between the first fixing member 101 and the second fixing member 102.
[0055] In practical applications, by providing adjustment holes 105 on the first fixing member 101 and / or the second fixing member 102, and connecting the fixing members to the cabinet 20 via locking members 104, the installation position of the filter assembly 100 can be flexibly adjusted. The extension direction of the adjustment hole 105 is consistent with the connection direction of the fixing member, allowing the first fixing member 101 or the second fixing member 102 to move along the extension direction of the adjustment hole 105, thereby adjusting the spacing between the fixing members. This design provides greater installation and maintenance flexibility, enabling the filter unit 103 to be precisely positioned and adjusted as needed. By adjusting the spacing, the first fixing member 101 and the second fixing member 102 can more accurately clamp the filter unit 103, thereby ensuring a more stable installation between the filter unit 103 and the cabinet 20, while preventing displacement of the filter unit 103 during operation and ensuring its long-term stable operation.
[0056] Optionally, refer to Figure 5 The first fixing member 101 and / or the second fixing member 102 are inclined toward the interior of the cabinet 20 relative to the plane where the air inlet 21 is located.
[0057] In practical applications, by tilting the first fixing member 101 and / or the second fixing member 102 towards the inside of the cabinet 20, the filter unit 103 can be effectively placed into the receiving cavity 25. The tilted design makes it easier for the filter unit 103 to be inserted and secured inside the receiving cavity 25, thus simplifying the installation process. Simultaneously, the tilt angle provides more space for the filter unit 103, allowing it to be smoothly inserted and avoiding interference with the cabinet 20 or other components. This design not only improves the ease of installation but also facilitates subsequent maintenance and replacement operations.

If the specific posture changes, the directional indicator will also change accordingly.
