Description

Technical Field

[0001] This utility model belongs to the field of energy storage technology, specifically relating to an energy storage container and an energy storage system having the same. Background Technology

[0002] Electric energy storage containers are used to store battery packs and related components. Distributed energy storage containers in related technologies concentrate battery packs, energy storage converters, water-cooled units and related spare parts in one container. However, due to the unreasonable layout of the container's compartments and air vents, the heat dissipation effect is poor, the space utilization rate is low when multiple containers are installed and arranged, and the water-cooled units have a significant impact on the noise interference of people in the surrounding area during operation. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose an energy storage container with a reasonable layout, convenient installation space arrangement, and reduced noise interference.

[0005] An embodiment of this utility model proposes an energy storage system.

[0006] The energy storage container of this utility model embodiment includes:

[0007] The box has a first compartment, a second compartment, and a third compartment. The first compartment is located above the second compartment. The box has a first side and a second side in the left-right direction. The third compartment is correspondingly arranged with the first compartment and the second compartment in the left-right direction and is adjacent to the first side of the box. The first side of the box has a first air inlet that communicates with the third compartment. The top of the box has a first air outlet that communicates with the third compartment. The second side of the box has a second air outlet that communicates with the second compartment.

[0048] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0049] See Figures 1 to 6 The energy storage container 100 of this utility model embodiment includes a container body 1 and a cooling unit 2.

[0050] The interior of the energy storage container 100 in this embodiment can be used to house the battery pack 81 and the energy storage converter 82. The cooling unit 2 can then be used to cool the battery pack 81 and the energy storage converter 82, ensuring their normal and stable operation.

[0051] The housing 1 in this embodiment has a first compartment 11, a second compartment 12, and a third compartment 13. Adjacent compartments can be separated by partitions, thereby allowing different types of equipment to be arranged in the first compartment 11, the second compartment 12, and the third compartment 13 respectively, avoiding interference between the equipment, giving the equipment in different compartments relatively independent spaces, making the space arrangement more reasonable, and improving space utilization.

[0052] The first compartment 11 is located above the second compartment 12. The box 1 has a first side and a second side in the left-right direction. The first side of the box 1 can be the general right side of the box 1 shown in the figure, and the second side of the box 1 can be the general left side of the box 1 shown in the figure. The third compartment 13 is arranged corresponding to the first compartment 11 and the second compartment 12 in the left-right direction, and the third compartment 13 is adjacent to the first side of the box 1 (i.e., the right side of the box 1 shown in the figure).

[0053] The first compartment 11 and the second compartment 12 can be separated by a horizontally arranged partition. A vertically arranged partition can be installed on the left side of the third compartment 13 to separate the third compartment 13 from the first compartment 11 and the second compartment 12.

[0054] The first compartment 11 has a relatively large internal volume and can be used to house the battery pack 81. The second compartment 12 has a relatively small internal volume and can be used to house the energy storage converter 82. Thus, the size of the first compartment 11 and the second compartment 12 can be reasonably allocated according to the space required by the battery pack 81 and the energy storage converter 82.

[0055] The first side of the housing 1 is provided with a first air inlet 14 that communicates with the third compartment 13. The gas entering the third compartment 13 flows in from the right side of the housing 1. The top of the housing 1 is provided with a first air outlet 15 that communicates with the third compartment 13. The second side of the housing 1 is provided with a second air outlet 16 that communicates with the second compartment 12. The cooling unit 2 is located in the third compartment 13. The cooling unit 2 is used to cool the equipment in the first compartment 11 and / or the second compartment 12. The air outlet end of the cooling unit 2 corresponds to the first air outlet 15. One end of the second compartment 12 adjacent to the first side of the housing 1 is connected to the third compartment 13. Part of the gas flowing into the third compartment 13 from the first air inlet 14 can be discharged through the first air outlet 15. Another part of the gas flowing into the third compartment 13 from the first air inlet 14 can flow out through the second compartment 12 and then through the second air outlet 16.

[0056] Part of the gas in the third compartment 13 can enter the cooling unit 2 for heat exchange, and then be discharged from the air outlet of the cooling unit 2 and discharged from the box 1 through the first air outlet 15. Another part of the gas in the third compartment 13 can enter the second compartment 12, cool down the equipment in the second compartment 12, and then be discharged from the left side of the box 1.

[0057] In this embodiment, the first air inlet 14 is located on the right side of the housing 1, and the gas discharged from the housing 1 is discharged from the top and left side of the housing 1. This can better control the direction of noise diffusion during the operation of the cooling unit 2, reduce the impact of noise on surrounding staff, and especially reduce the impact of noise on staff in front of the housing 1.

[0058] Meanwhile, this embodiment does not require an exhaust vent at the rear of the container 1. When the energy storage container 100 is arranged, the rear of the energy storage container 100 can be closer to the building or another energy storage container 100, thereby improving the space utilization of the arrangement site without affecting heat dissipation.

[0059] The cooling unit 2 can be a water-cooled unit, which can be connected to the liquid cooling plate in the first compartment 11 and / or the second compartment 12, thereby cooling the equipment in the first compartment 11 and / or the second compartment 12.

[0060] Furthermore, the length direction of the box 1 is roughly the left-right direction as shown in the figure, the height direction of the box 1 is roughly the up-down direction as shown in the figure, the width direction of the box 1 is roughly the front-back direction as shown in the figure, the door 17 is usually located at the front of the box 1, and the front-back direction of the box 1 is also the depth direction of each compartment.

[0061] The energy storage container 100 of this embodiment of the invention achieves a reasonable distribution of the battery pack 81, energy storage converter 82, and cooling unit 2 by rationally dividing the space of the container 1, resulting in high space utilization of the container 1. In this embodiment, the first air inlet 14 is located on the first side of the container 1, and the first air outlet 15 is located on the top of the container 1. This allows noise to diffuse towards the top of the container 1, reducing noise on the front side of the container 1, minimizing noise interference to surrounding people, and improving the user experience. When multiple containers are arranged side by side, the distance between the rear wall panels of adjacent containers 1 can be brought closer, resulting in higher space utilization of the arrangement site without affecting overall heat dissipation. In this embodiment, some of the gas in the third compartment 13 can flow into the second compartment 12 to dissipate heat from the equipment in the second compartment 12, resulting in higher heat dissipation efficiency.

[0062] In some embodiments, a first fan 51 is provided at the second air outlet 16. The first fan 51 is used to draw out the gas in the second chamber 12 so that the gas in the third chamber 13 can flow into the second chamber 12. The first fan 51 is used to draw out the gas in the second chamber 12, thereby increasing the gas flow rate in the second chamber 12 so as to control the temperature in the second chamber 12 within a stable range.

[0063] In application, the speed of the first fan 51 can be adjusted according to the temperature inside the second compartment 12. When the temperature inside the second compartment 12 is high, the speed of the first fan 51 is increased, and when the temperature inside the second compartment 12 is low, the speed of the first fan 51 is decreased, thereby achieving energy saving and consumption reduction.

[0064] Furthermore, in this embodiment, there can be multiple second air outlets 16, which are arranged at intervals along the front-to-back direction. Alternatively, the second air outlets 16 can be elongated, with their length extending along the front-to-back direction. This allows for more uniform and consistent gas flow within the second chamber 12, enabling better removal of heat emitted by the equipment within the second chamber 12 and improving the temperature uniformity of different areas within the second chamber 12.

[0065] The connecting holes between the second compartment 12 and the third compartment 13 can also be multiple or elongated connecting holes arranged at intervals along the front-back direction, which can improve the uniformity of airflow entering the second compartment 12.

[0066] Since the space volume of the second compartment 12 is relatively small, mainly reflected in the relatively small size of the second compartment 12 in the vertical direction, after the energy storage converter 82 and other equipment are arranged in the second compartment 12, a certain space can be reserved above the equipment and between the top wall of the second compartment 12 to facilitate gas flow, and at the same time facilitate the cold air to come into contact with more equipment, improve the heat dissipation effect of the equipment in the second compartment 12, and ensure the stable operation of the equipment.

[0067] Furthermore, the first air inlet 14 is an open structure; for example, no wall panel is provided on the first side of the housing 1, thereby facilitating the entry of cold air into the first flow channel 31 and the interior of the cooling unit 2. To prevent foreign objects from entering the third compartment 13, a protective plate with air vents, such as a grid plate or a perforated plate, can be provided at the first air inlet 14, thereby providing protection without affecting air intake.

[0068] The first air outlet 15 is an open structure. For example, the wall panel on the top of the housing 1 only covers the top of the first compartment 11, and the top of the housing 1 corresponding to the third compartment 13 is not equipped with a wall panel. This facilitates the discharge of hot gas flowing through the second flow channel 32 and the hot gas flowing through the interior of the cooling unit 2. To prevent foreign objects from entering the third compartment 13, a protective plate with air passage holes, such as a grid plate or a perforated plate, can be provided at the first air outlet 15. This provides protection without affecting the air outlet.

[0069] like Figure 3 and Figure 4 As shown, in some embodiments, a first flow channel 31 is constructed between the lower part of the cooling unit 2 and the inner wall of the third chamber 13. The first flow channel 31 corresponds to and is connected to the communication port between the second chamber 12 and the third chamber 13. Part of the gas entering the third chamber 13 can flow into the second chamber 12 after passing through the first flow channel 31.

[0070] Figure 3 The diagram shows the airflow direction of cold air as it flows from the first air inlet 13 through the third chamber 13 and the second chamber 12, and is then discharged from the second air outlet 16.

[0071] Since the second compartment 12 is located near the bottom of the housing 1, in order to facilitate the timely flow of cold air into the second compartment 12 after entering the third compartment 13, this embodiment constructs a first flow channel 31 between the bottom of the cooling unit 2 and the bottom wall of the third compartment 13. Specifically, the cooling unit 2 and the bottom wall of the third compartment 13 are spaced apart, thereby constructing the first flow channel 31. The cold air flows more smoothly between the first air inlet 14, the first National VI channel, the second compartment 12 and the second air outlet 16, reducing air resistance and preventing the cold air flowing through the first flow channel 31 from being heated by the heat of the cooling unit 2 itself, thus reducing the temperature change of the cold air when flowing through the third compartment 13.

[0072] The cooling unit 2 can be directly fixed to the side wall of the third compartment 13, or it can be fixed to the bottom wall of the third compartment 13 by means of a support. When the support is installed, the support can avoid the connecting hole between the third compartment 13 and the second compartment 12 as much as possible, so as to avoid the connection seat from obstructing the airflow to the second compartment 12.

[0073] like Figure 4 As shown, in some embodiments, a second flow channel 32 is constructed between the front side of the cooling unit 2 and the inner wall of the third chamber 13. The second flow channel 32 is connected to the first air outlet 15, and part of the gas entering the third chamber 13 can be discharged through the second flow channel 32 and then through the first air outlet 15.

[0074] A second flow channel 32 is constructed by spacing between the front side of the cooling unit 2 and the inner wall of the third compartment 13 (which can be the inner wall of the door 17 of the third compartment 13). The cold air flowing into the bottom of the third compartment 13 enters the second compartment 12 in part, and the other part flows through the second flow channel 32 to the top of the third compartment 13 and is discharged from the first air outlet 15. The cold air in the second flow channel 32 can exchange heat with the outer wall of the cooling unit 2 to achieve cooling and temperature reduction of the cooling unit 2 itself and improve the working stability of the cooling unit 2.

[0075] like Figure 4 As shown, in some embodiments, the energy storage container 100 also includes a fire extinguishing device 4, which is located in the third compartment 13 and below the cooling unit 2. The fire extinguishing device 4 has multiple spray nozzles distributed in the first compartment 11 and / or the second compartment 12. During the operation of the energy storage container 100, if thermal runaway occurs, the fire extinguishing device 4 can directionally spray extinguishing material to extinguish the fire source according to the detected ignition point, effectively covering the thermal runaway point. This allows for millisecond-level linkage from detection to spraying in the early stages of thermal runaway, resulting in better fire extinguishing capabilities.

[0076] The fire extinguishing device 4 is placed in the third compartment 13, which can improve the space utilization of the third compartment 13. Under the premise of ensuring the effective flow area of ​​the first flow channel 31, the space below the cooling unit 2 is fully utilized to improve the integration and compactness of the equipment and increase the power density of the energy storage container 100.

[0077] The fire extinguishing device 4 can be a perfluorohexanone fire extinguishing device 4.

[0078] like Figure 1 and Figure 2As shown, in some embodiments, the front wall panel of the housing 1 is constructed as a plurality of compartment doors 17, each of the first compartment 11, the second compartment 12, and the third compartment 13 corresponding to at least a portion of the compartment doors 17. This facilitates the inspection, maintenance, installation, and disassembly of the equipment, and during operation, only the corresponding compartment door 17 can be opened, making it practical and convenient to operate.

[0079] In some embodiments, the energy storage container 100 further includes a vent indicator light 61, an audible and visual alarm 62, an emergency stop button 63, a manual alarm button 64, and a manual start button 65. These are located on the door 17 at the front of the third compartment 13. This facilitates centralized control and allows for the placement of the control panel within the third compartment 13, resulting in better stability. In this embodiment, the vent indicator light 61, audible and visual alarm 62, emergency stop button 63, manual alarm button 64, and manual start button 65 are positioned away from the front of the first compartment 11 and the second compartment 12, preventing the corresponding operation buttons from malfunctioning directly in the event of thermal runaway in either the first compartment 11 or the second compartment 12, thus improving stability.

[0080] The energy storage container 100 also includes a water fire hydrant 66 and a pressure relief window 67. The water fire hydrant 66 and the pressure relief window 67 are located on the wall panel on the second side of the container 1. This allows the pressure relief window 67 to facilitate pressure relief inside the container 1, regulate the pressure inside the container during normal operation, and ensure relatively stable pressure. The water fire hydrant 66 is used to connect to fire water pipes. The water fire hydrant 66 is located on the second side of the container 1 (the left side of the container 1 shown in the figure) for easy connection and to avoid being blocked by other equipment, thus improving its practicality.

[0081] In some embodiments, the energy storage container 100 further includes a mounting frame 7 disposed within the first compartment 11 and / or the second compartment 12 to create multiple mounting positions within the first compartment 11 and / or the second compartment 12. By setting up the mounting frame 7, multiple mounting positions can be formed, thereby allowing for aligned installation of the battery pack 81 or the energy storage converter 82. This also allows for a more rational determination of the spacing between adjacent battery packs 81 or adjacent energy storage converters 82, facilitating aligned placement and orderly stacking. Furthermore, it facilitates wiring, enabling the equipment to be arranged in an array, resulting in a more organized and efficient system that helps improve the power density of the energy storage container 100.

[0082] Furthermore, the mounting frame 7 includes a frame body 71 and guide rail grooves 72. Multiple frame bodies 71 are arranged side-by-side and spaced apart in the left-right direction, and multiple guide rail grooves 72 are spaced apart in the up-down direction on the frame bodies 71. The guide rail grooves 72 on adjacent frame bodies 71 correspond one-to-one, forming multiple mounting positions. The frame body 71 can be connected to the housing 1. The frame body 71 is plate-shaped, and multiple frame bodies 71 are arranged spaced apart in the left-right direction. Each frame body 71 has multiple guide rail grooves 72, and the guide rail grooves 72 on adjacent frame bodies 71 correspond one-to-one, forming multiple mounting positions. Guide rails can be provided on the battery pack 81, allowing the battery pack 81 to be supported on two oppositely arranged guide rail grooves 72 and to move along the guide rail grooves 72, facilitating assembly. In this embodiment, a battery cluster is formed between two adjacent frame bodies 71. Especially for the space of the first compartment 11, the space of the first compartment 11 can be divided into an array, facilitating battery arrangement and connection, improving practicality, and increasing space utilization.

[0083] In some embodiments, the top wall panel of the container 1 is provided with a plurality of explosion vents 68. The explosion vents 68 are weakly connected to the container 1. When an explosion occurs inside the container, the explosion vents 68 will be blown open first, thereby effectively preventing other parts of the container from being blown open and causing injury to outside personnel.

[0084] Furthermore, each of the boxes 1 above the space between two adjacent mounting brackets 7 is provided with a vent 68, which can more promptly and effectively relieve pressure when the battery pack 81 explodes.

[0085] See Figure 1 and Figure 2 In some embodiments, the first chamber 11 has a first end corner and a second end corner arranged along a diagonal line. The housing 1 is provided with a second air inlet 18 and a third air outlet 19, one of which is adjacent to the second end corner, and the other is also adjacent to the second end corner. In this embodiment, the diagonal line refers to the diagonal line passing through the middle of the first chamber 11. Gas flowing into the first chamber 11 from the second air inlet 18 can diffuse throughout the first chamber 11 and finally converge at the third air outlet 19 for discharge. This results in good gas flow, good gas diffusion within the first chamber 11, and high gas replacement efficiency. During internal inspection or maintenance, harmful gases within the housing 1 can be replaced first, reducing the health hazards to workers.

[0086] When a fire occurs inside the container, harmful gases inside need to be discharged in time. Fresh air can be blown into the first compartment 11 through the second air inlet 18, while toxic and harmful gases can be discharged from the container through the third air outlet 19. This method has high replacement efficiency and improves the efficiency of harmful gas discharge.

[0087] Furthermore, a second fan 52 is provided at the second air inlet 18, which is used to blow air into the first chamber 11, and a third fan 53 is provided at the third air outlet 19, which is used to exhaust gas from the first chamber 11. In this embodiment, the second fan 52 can force air into the first chamber 11, and the third fan 53 can force gas out of the first chamber 11, thereby increasing the gas flow rate in the first chamber 11 and improving the replacement rate of fresh air and harmful gases in the first chamber 11, resulting in better handling of emergency situations.

[0088] Preferably, in this embodiment, the second air inlet 18 is located on the front wall panel of the housing 1, adjacent to the second compartment 12 and the third compartment 13. As shown in the figure, the second air inlet 18 is located on the lower right side of the front wall panel of the first compartment 11. The third air outlet 19 is located on the second side wall panel of the housing 1, adjacent to the top wall panel and the rear wall panel of the housing 1. As shown in the figure, the third air outlet 19 is located on the upper rear side of the left side wall panel of the housing 1.

[0089] This not only prevents the fresh air entering the first chamber 11 from being affected by other exhaust vents, but also ensures that the harmful gases displaced by the first chamber 11 do not affect surrounding staff, thus reducing the impact on those around them. In this embodiment, the fresh air enters the lower right front part of the first chamber 11 and gradually diffuses, which helps the harmful gases in the first chamber 11 to gather and be discharged in an upward direction along the upper right rear side of the first chamber 11, resulting in a good replacement effect.

[0090] In some embodiments, the rear wall panel of the container 1 is a complete wall panel. This embodiment ensures that the rear wall panel of the container 1 is intact, without providing openings in the rear wall panel of the container 1. This allows the rear wall panel to be closer to buildings or other containers during installation, reducing the space requirements for the installation site.
