[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 As shown, Figure 1 is an overall schematic diagram of an energy storage device provided by an embodiment of the present invention, Figure 2 is a front view of an energy storage cabinet provided by an embodiment of the present invention, Figure 3 is a partial structural diagram of an energy storage cabinet provided in an embodiment of the present invention, Figure 4 The embodiment of the present invention provides Figure 3 The schematic diagram of the cross-sectional structure at AA in the middle and the partial enlarged schematic diagram of the B area, Figure 5 It is a schematic diagram of the local structure of the unassembled filter unit 103 and a schematic diagram of the local enlargement of the D area provided by the embodiment of the present invention.

[0030] The embodiment of the present invention provides an energy storage system, including a battery pack 110 and an energy storage cabinet, wherein the battery pack 110 is installed inside the energy storage cabinet.

[0031] Specifically, the energy storage cabinet includes: a cabinet 20 and a plurality of blades 30, the cabinet 20 is provided with an air inlet 21, and the air inlet 21 is connected to the inside of the cabinet 20. The plurality of blades 30 cover the air inlet 21, and the plurality of blades 30 are arranged at intervals in the cabinet 20, and a first air duct 40 and a second air duct 50 are formed between adjacent blades 30. In the depth direction of the cabinet 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 inside of the cabinet 20, and the other end is connected to the second air duct 50, and the end of the second air duct 50 away from the first air duct 40 is connected to the outside of the cabinet 20, the first air duct 40 is arranged at intervals from the outside of the cabinet 20, and the second air duct 50 is arranged at intervals from the inside of the cabinet 20.

[0032] In practical applications, by setting a plurality of blades 30 and the corresponding first air duct 40 and second air duct 50, this design effectively blocks raindrops and external dirt from entering the interior of the cabinet 20. First, the blades 30 can directly block most raindrops and prevent them from directly entering the interior of the cabinet 20; even if a small amount of rainwater enters the second air duct 50 due to the sputtering effect of the blades 30, due to the interval between the second air duct 50 and the interior of the cabinet 20, the rainwater in the second air duct 50 cannot flow further into the interior of the cabinet 20, thereby reducing the potential damage of external liquids such as rainwater to the battery pack 110 and electrical equipment inside the cabinet 20. At the same time, the second air duct 50 is connected to the first air duct 40 to form an effective ventilation path, and the external low-temperature air can flow into the interior of the cabinet 20 through the second air duct 50 and the first air duct 40 in turn for air cooling and heat dissipation, 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 the waterproof and dustproof functions, 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 portion 31, a second portion 32, a third portion 33 and a fourth portion 34. The first portion 31 is connected to the cabinet 20. The opposite ends of the first portion 31 are respectively connected to the second portion 32 and the third portion 33. The second portion 32 and the third portion 33 extend in a direction away from the interior of the cabinet 20. One end of the third portion 33 away from the first portion 31 is connected to the fourth portion 34. The fourth portion 34 extends in a direction away from the second portion 32.

[0034] A first air duct 40 is formed between the second portion 32 and the third portion 33 and the fourth portion 34 of the adjacent blade 30, and the first air duct 40 is spaced apart from the fourth portion 34 and the outside of the cabinet 20. A second air duct 50 is formed between the first portion 31, the second portion 32, the third portion 33 and the fourth portion 34 of the adjacent blade 30, and the second air duct 50 is spaced apart from the first portion 31 and the inside of the cabinet 20. The second air duct 50 is downwardly arranged away from the opening inside the cabinet 20 to reduce rainwater directly entering the second air duct 50 from the opening of the second air duct 50.

[0035] In actual application, the blade 30 includes a first portion 31, a second portion 32, a third portion 33 and a fourth portion 34, and the third portion 33 and the fourth portion 34 are arranged outside the second air duct 50, thereby directly blocking rainwater and external dirt from entering the second air duct 50. The rainwater is first intercepted by the third portion 33 and the fourth portion 34 and cannot enter the second air duct 50, thereby protecting the equipment in the cabinet 20 from moisture and pollution. Even if a small amount of rainwater splashes into the second air duct 50, it will be blocked by the first portion 31, the second portion 32 and the third portion 33 and the fourth portion 34 of the adjacent blade 30, and cannot further enter the interior of the cabinet 20 through the first air duct 40. At the same time, the connection between the second air duct 50 and the first air duct 40 ensures that the external low-temperature gas can smoothly enter the interior of the cabinet 20 through the second air duct 50 and the first air duct 40, thereby providing effective air cooling and heat dissipation, 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 and stable operation of the equipment.

[0036] Further, see Figure 5 The blade 30 includes a fifth portion 35, the fifth portion 35 is connected to an end of the fourth portion 34 away from the third portion 33, the fifth portion 35 is inserted into the second air duct 50, and separates the second air duct 50 to form a first sub-air duct 51 and a second sub-air duct 52, and the second air duct 50 is spaced apart by the first portion 31 and the inside of the cabinet 20;

[0037] A first sub-duct 51 is formed between the fifth portion 35 and the first portion 31 and the third portion 33 of the adjacent blade 30, and both ends of the first sub-duct 51 are respectively connected to the second sub-duct 52 and the outside of the cabinet 20. A second sub-duct 52 is formed between the fifth portion 35 and the first portion 31 and the second portion 32 of the adjacent blade 30, and the first duct 40 is connected to the first sub-duct 51 through the second sub-duct 52.

[0038] In actual application, the air duct system of the energy storage cabinet is further optimized by adding the fifth part 35 to the blade 30 structure. The fifth part 35 divides the original second air duct 50 into the first sub-air duct 51 and the second sub-air duct 52, and forms a more refined air flow channel. First, the third part 33, the fourth part 34 and the fifth part 35 together constitute the side walls of the first air duct 40 and the second sub-air duct 52 from different directions, which significantly improves the isolation effect of rainwater. In this way, after the splashed rainwater enters the first sub-air duct 51, it can be effectively blocked by the side wall 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] The airflow passes through the first sub-air duct 51, the second sub-air duct 52 and the first air duct 40 in sequence and enters the cabinet 20 for air cooling and heat dissipation, ensuring good heat dissipation performance inside the energy storage cabinet, not only effectively preventing rainwater and other liquids from entering the cabinet 20, but also ensuring that the air flow inside the cabinet 20 is not hindered, providing a more stable and efficient heat dissipation effect. When the energy storage cabinet is in severe weather conditions, it can better protect the internal electrical equipment, extend the service life of the equipment, and improve the overall reliability of use.

[0040] Further, see Figure 5 The second sub-air duct 52 is arranged obliquely 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 resistance of the airflow in the channel is increased, and the flow rate of the airflow in the first sub-duct 51 and the second sub-duct 52 is reduced. At the same time, the distance that the airflow flows through these ducts is extended, so that the water vapor and liquid carried in the airflow have more time to adhere to the inner wall of the duct. This design effectively reduces the possibility of water vapor and liquid entering the cabinet 20, thereby effectively preventing the potential impact of water vapor on the electrical equipment inside the cabinet 20.

[0042] In this embodiment, the angle between the first sub-duct 51 and the second sub-duct 52 is an acute angle, so that the first sub-duct 51 and the second sub-duct 52 form a V-shape, and the first duct 40, the first sub-duct 51 and the second sub-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. The air inlet 21 is opened in the first base 22. The first baffle 23 is arranged on 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 direction close to the inside 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 outside of the first base 22. The fourth air duct 60 is spaced apart from the inside of the first base 22 through the fifth air duct 70. One end of the fifth air duct 70 is connected to the inside of the first base 22, and the other end is spaced apart from the outside of the first base 22 through the fourth air duct 60.

[0044] In practical applications, by setting a first baffle 23 at one end of the air inlet 21 of the energy storage cabinet, and forming a fourth air duct 60 and a fifth air duct 70 between the blade 30 and the first baffle 23, the external low-temperature airflow can enter the cabinet 20 through the fourth air duct 60 and the fifth air duct 70 in sequence, and effectively cool the cabinet 20. At the same time, the first baffle 23 effectively blocks external rainwater and pollutants, preventing them from entering the cabinet 20. Such a design not only improves the air-cooling and heat dissipation efficiency inside the cabinet 20, but also reduces the entry of water vapor or pollutants, thereby improving the service life and stability of the electrical equipment inside the cabinet 20.

[0045] Further, refer to Figure 4 and Figure 5 The cabinet 20 includes a second baffle 24, which is arranged on the first base 22 and is located at one 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 in a direction 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 outside of the first base 22. The sixth air duct 80 is spaced apart from the inside of the first base 22 through the seventh air duct 90. One end of the seventh air duct 90 is connected to the inside of the first base 22, and the other end is spaced apart from the outside of the first base 22 through the sixth air duct 80.

[0046] In practical applications, by setting a second baffle 24 at one end of the air inlet 21 of the energy storage cabinet away from the first baffle 23, and forming a sixth air duct 80 and a seventh air duct 90 between the blade 30 and the second baffle 24, the external low-temperature airflow can enter the cabinet 20 through the sixth air duct 80 and the seventh air duct 90 in sequence, further enhancing the air-cooling and heat dissipation effect inside the cabinet 20. At the same time, the second baffle 24 effectively blocks external rainwater and pollutants, preventing them from entering the cabinet 20. Such a design not only improves the heat dissipation efficiency of the cabinet 20, but also reduces the entry of water vapor or pollutants, further improving the operating stability and service life of the electrical equipment.

[0047] In one embodiment, referring to Figure 1 and Figure 3 The energy storage cabinet includes a filter assembly 100 , and the filter assembly 100 includes a filter portion 103 . The filter portion 103 is disposed inside the cabinet body 20 and covers the air inlet 21 .

[0048] In practical applications, by arranging the filter assembly 100 inside the energy storage cabinet, and the filter part 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, thereby preventing these pollutants from entering the cabinet 20. This design not only helps to keep the air inside the cabinet 20 clean and reduce 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 filter unit 103 may be a mesh filter, a foam filter, or an activated carbon filter.

[0050] Further, refer to Figure 3 and Figure 4 The filter assembly 100 includes a first fixing member 101 and a second fixing member 102, which are respectively arranged on the cabinet 20 and located at opposite ends of the air inlet 21. An accommodating cavity 25 is formed between the first fixing member 101 and the second fixing member 102, and the filter part 103 is arranged inside the accommodating cavity 25. The first fixing member 101 and the second fixing member 102 are used to limit the filter part 103.

[0051] In practical applications, by respectively providing a first fixing member 101 and a second fixing member 102 at both ends of the air inlet 21 of the energy storage cabinet, and forming a receiving chamber 25 therebetween, the filter unit 103 can be stably received. The filter unit 103 is confined within the receiving chamber 25 to ensure 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 it difficult for the filter unit 103 to shift or fall off, thereby enhancing the structural stability and sealing of the filter assembly 100. This design not only improves the filtering effect, but also ensures smooth airflow of 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 a direction perpendicular to the plane where the air inlet 21 is located, the thickness of the accommodating cavity 25 is greater than the thickness of the filter portion 103 .

[0053] In practical applications, by setting the thickness of the accommodating cavity 25 to be greater than the thickness of the filter unit 103, the accommodating space between the filter unit 103 and the cabinet 20 can be effectively increased, providing more room for the installation of the filter unit 103. In particular, when the filter unit 103 is made of foam or sponge material, the larger accommodating space can provide more room for expansion, ensuring that the filter unit 103 can be fully expanded and maintain a good filtering effect. This design not only makes the installation of the filter unit 103 more stable, but also provides sufficient space for subsequent maintenance and replacement, thereby improving the convenience of use of the energy storage cabinet. In addition, the larger accommodating space can prevent the filter unit 103 from being damaged due to excessive expansion, extend its service life, and ensure 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 is provided with an adjustment hole 105, the extension direction of the adjustment hole 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, the locking member 104 is passed through the adjustment hole 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 hole 105 to adjust the distance between the first fixing member 101 and the second fixing member 102.

[0055] In practical applications, by setting an adjustment hole 105 on the first fixing member 101 and / or the second fixing member 102, and connecting the fixing member and the cabinet 20 through a locking member 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, so that the filter unit 103 can be accurately positioned and adjusted as needed. By adjusting the spacing, the first fixing member 101 and the second fixing member 102 can clamp the filter unit 103 more accurately, thereby ensuring that the installation between the filter unit 103 and the cabinet 20 is more stable, while avoiding displacement of the filter unit 103 during operation, ensuring its long-term stable operation.

[0056] Optionally, refer to Figure 5 Relative to the plane where the air inlet 21 is located, the first fixing member 101 and / or the second fixing member 102 are arranged to be inclined toward the direction close to the interior of the cabinet 20.

[0057] In practical applications, by tilting the first fixing member 101 and / or the second fixing member 102 toward the inside of the cabinet 20, it is possible to effectively facilitate the placement of the filter unit 103 into the accommodating cavity 25. The tilted design allows the filter unit 103 to be more easily inserted and fixed inside the accommodating cavity 25, thereby simplifying the installation process of the filter unit 103. At the same time, the tilt angle can provide a larger space for the filter unit 103, allowing it to be smoothly placed and avoid interference with the cabinet 20 or other components. This design not only improves the convenience of installation, but also facilitates subsequent maintenance and replacement operations.
