Description

Technical Field

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

[0002] In related technologies, energy storage systems include duct components that direct cold air from the air conditioning system to the battery modules on the rack. Current duct components are installed in various ways: some are directly on top of the rack; some are installed on the back of the rack; and others are installed on the insulation panel or top beam inside the storage compartment. This not only makes maintenance and component replacement inconvenient, but also leads to unreliable connections that risk displacement of the duct components, causing significant problems for heat dissipation and the connection between the duct components and the air conditioning vents. Summary of the Invention

[0003] This invention provides an energy storage system.

[0004] An energy storage system according to an embodiment of the present invention includes:

[0005] The accommodating compartment has an accommodating space inside, and the top of the accommodating space is provided with an installation plate;

[0006] A battery module, wherein the battery module is disposed within the accommodating space;

[0007] A cooling duct assembly, located within the accommodating space, is used to dissipate heat from the battery module.

[0008] An adapter assembly connects the air duct assembly and the mounting plate; wherein the adapter assembly is fixedly connected to the mounting plate and detachably connected to the air duct assembly.

[0009] The aforementioned energy storage system uses an adapter to mount the air duct assembly onto a top mounting plate. The adapter has a large connection area with the mounting plate, which reduces the deformation of the mounting plate and thus minimizes the displacement of the air duct assembly caused by the deformation. This reduces the adverse effects on air duct heat dissipation and the impact on the connection between the air duct assembly and the air conditioner outlet, maximizing the utilization rate of the cooled air blown out by the air conditioner and improving the heat dissipation effect. At the same time, the detachable connection of the adapter to the air duct assembly also facilitates the maintenance and replacement of components in the energy storage system.

[0010] In some implementations, the connection between the adapter assembly and the mounting plate is continuous.

[0011] This further reduces the deformation of the mounting plate.

[0012] In some embodiments, the adapter assembly is connected to the mounting plate by welding.

[0013] This ensures a secure connection between the adapter assembly and the mounting plate.

[0014] In some embodiments, the air duct assembly includes: an air inlet section, a middle section, and an air outlet section arranged in sequence; cold air enters through the air inlet section and flows through the middle section, and flows out from the air outlet section and toward the battery module to dissipate heat.

[0015] Along the flow direction of the cold air, the duct assembly includes a first mounting side plate disposed in the middle section and a second mounting side plate disposed in the air outlet section. The first mounting side plate is gradually inclined in a direction away from the central axis of the duct assembly, and the second mounting side plate is parallel to the central axis of the duct assembly.

[0016] This increases the air outlet area of ​​the air duct components and improves the heat dissipation uniformity of the battery module.

[0017] In some embodiments, the adapter component includes:

[0018] First disassembly / reassembly plate;

[0019] The second detachable plate is detachably connected to the first mounting side plate and the second detachable plate, and the second detachable plate is fixedly connected to the mounting plate.

[0020] The third detachable plate is detachably connected to the second mounting side plate and is fixedly connected to the mounting plate.

[0021] In this way, the air duct assembly can be mounted more stably on the mounting plate.

[0022] In some embodiments, the first mounting side plate has a first connecting portion, the first detachable plate has a second connecting portion, and the first detachable plate and the first mounting side plate are detachably connected by a first fastener passing through the first connecting portion and the second connecting portion.

[0023] This makes it convenient to assemble and disassemble the air duct components.

[0024] In some embodiments, the first mounting plate is provided with a first mounting hole, and the second mounting plate is provided with a second mounting hole. The first mounting plate and the second mounting plate are detachably connected by a second fastener passing through the first mounting hole and the second mounting hole.

[0025] This improves the assembly efficiency of the first and second disassembly plates.

[0026] In some embodiments, the first detachable plate includes a first sub-plate and a second sub-plate that are vertically connected, and the first sub-plate is detachably connected to the first mounting side plate;

[0027] The second detachable plate includes a base plate perpendicular to each other and two support plates. The two support plates are connected to the two sides of the base plate in the width direction. The base plate is detachably connected to the second sub-plate, and the two support plates are fixedly connected to the mounting plate.

[0028] This ensures that the air duct components are installed in the correct positions.

[0029] In some embodiments, the second mounting side plate has a third connecting portion, and the third detachable plate has a fourth connecting portion. The third detachable plate and the second mounting side plate are detachably connected by a third fastener passing through the third connecting portion and the fourth connecting portion.

[0030] This makes it convenient to assemble and disassemble the air duct components.

[0031] In some embodiments, the first mounting side plate and the second mounting side plate are provided with a fixed mounting part and an adjustable mounting part arranged in a vertical direction, the adjustable mounting part being located below the fixed mounting part, the first connecting part being either the fixed mounting part or the adjustable mounting part, and the third connecting part being either the fixed mounting part or the adjustable mounting part.

[0032] This facilitates the maintenance or replacement of the cluster rack.

[0033] In some embodiments, when both the first connecting portion and the third connecting portion are fixed mounting portions, the air duct assembly is located in a first position; when both the first connecting portion and the third connecting portion are adjustable mounting portions, the air duct assembly is located in a second position; wherein the height of the first position is lower than the height of the second position.

[0034] In this way, the height of the air duct assembly can be adjusted.

[0035] In some embodiments, a substrate is provided at the bottom of the accommodating space;

[0036] The energy storage system also includes:

[0037] A cluster frame is mounted on the substrate and located below the air duct assembly, and the edge of the substrate is provided with a baffle.

[0038] The energy storage system meets the following conditions:

[0039] H2+H3>H1;

[0040] Wherein, H1 represents the height of the baffle relative to the substrate, H2 represents the vertical distance between the air duct assembly and the cluster frame when the air duct assembly is in the first position, and H3 represents the vertical distance between the fixed mounting part and the adjustable mounting part.

[0041] This further improves the ease of maintenance or replacement of the cluster rack.

[0042] In some embodiments, the side panel of the accommodating compartment is provided with a door frame, and the energy storage system satisfies the following conditions:

[0043] W1>W2, where W1 represents the width of the door frame and W2 represents the width of the air duct assembly.

[0044] This allows the air duct components to be easily moved outside the containment chamber.

[0045] In some embodiments, the energy storage system includes:

[0046] Air conditioning unit, wherein the air conditioning unit is provided with an air outlet;

[0047] A duct adapter connects the air inlet section and the air outlet, and the connection between the duct adapter and the duct assembly is detachable.

[0048] In this way, the positions of the air conditioning components and air duct components can be adapted.

[0049] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0070] Please refer to Figures 1 to 4 An energy storage system 100 provided by an embodiment of the present invention includes a housing 12, a battery module 13, a cooling duct assembly 14, and a connecting assembly 18. The housing 12 has a housing space 20, and a mounting plate 22 is provided on the top of the housing space 20. The battery module 13 is disposed within the housing space 20. The cooling duct assembly 14 is located in the housing space 20 and is used to dissipate heat from the battery module 13. The connecting assembly 18 connects the cooling duct assembly 14 and the mounting plate 22. Specifically, the connecting assembly 18 is fixedly connected to the mounting plate 22, and detachably connected to the cooling duct assembly 14.

[0071] The aforementioned energy storage system 100 uses an adapter component 18 to mount the air duct component 14 onto the top mounting plate 22. The adapter component 18 has a large connection area with the mounting plate 22, which can reduce the deformation of the mounting plate 22. This reduces the displacement of the air duct component 14 caused by the deformation of the mounting plate 22, thereby reducing the adverse effects on air duct heat dissipation and the impact on the connection between the air duct component and the air conditioner outlet. This maximizes the utilization rate of the cool air blown out by the air conditioner and improves the heat dissipation effect. At the same time, the detachable connection of the adapter component 18 to the air duct component 14 also facilitates the maintenance and component replacement of the energy storage system 100.

[0072] Specifically, the present invention does not impose specific limitations on the material of the storage compartment 12. In one embodiment, the storage compartment 12 may be made of stainless steel or iron, and the storage compartment 12 may be manufactured in the form of a container. The present invention also does not impose specific limitations on the shape of the storage compartment 12. Figure 1 In this embodiment, the accommodating compartment 12 is rectangular in shape.

[0073] The accommodating space 20 can house various components of the energy storage system 100, including but not limited to battery clusters 24, high-voltage cabinets 26, and fire-fighting equipment 28. In one embodiment, a mounting plate 22 is provided at the top of the accommodating space 20. The mounting plate 22 can be an insulation board, which can be made of steel plate. The adapter component 18 connects the air duct assembly 14 and the mounting plate 22. On the one hand, it allows the air duct assembly 14 to be installed in the accommodating space 20. On the other hand, the connection area between the adapter component 18 and the mounting plate 22 is large, which can distribute the force exerted by the air duct assembly 14 on the mounting plate 22 (mainly the weight of the air duct assembly 14) to more positions on the mounting plate 22, reducing the deformation of the mounting plate 22. This reduces the displacement of the air duct assembly 14 due to the deformation of the mounting plate 22, thereby reducing the adverse effects on air duct heat dissipation and the impact on the connection between the air duct assembly 14 and the air conditioning outlet.

[0074] The adapter component 18 can be detachably connected to the air duct component 14 via a snap-fit ​​method, screw connection method, etc. This detachable connection of the adapter component 18 to the air duct component 14 also facilitates the maintenance and component replacement of the energy storage system 100.

[0075] The air duct assembly 14 is equipped with an air duct, which can guide the cooling air to the battery cluster 24, so that the battery module 13 of the battery cluster 24 can operate within a suitable temperature range.

[0076] exist Figure 2 In the illustrated embodiment, the accommodating space 20 contains a plurality of battery clusters 24 arranged in an array. Each battery cluster 24 has a top air duct assembly 14 and includes a cluster frame 84 (see...). Figure 4 The battery clusters 24 and multiple battery modules 13 mounted on the cluster rack 84 can be electrically connected in series, parallel, or series-parallel configurations.

[0077] The energy storage system 100 may include multiple door frames 30, which are respectively located on the front and rear side panels of the housing 12. Each door frame 30 corresponds to the position of a battery cluster 24. A door body 32 is installed on the door frame 30, and an air conditioning component 34 can be installed on the outer side of the door body 32.

[0078] It is understood that in other embodiments, a battery cluster 24 may also be provided in the accommodating space 20, and the number of battery clusters 24 placed in the accommodating space 20 is not specifically limited here.

[0079] In some implementations, the connection formed by the adapter 18 and the mounting plate 22 is continuous.

[0080] This further reduces the deformation of the mounting plate 22.

[0081] Specifically, the connection between the adapter component 18 and the mounting plate 22 is continuous, so that the force exerted by the air duct component 14 on the mounting plate 22 can be continuously distributed along the connection.

[0082] In addition, the connection between the adapter component 18 and the mounting plate 22 can be a surface connection, which further increases the connection area between the adapter component 18 and the mounting plate 22, and the force exerted by the air duct component 14 on the mounting plate 22 can be distributed more widely.

[0083] In summary, this can further reduce the deformation of the mounting plate 22.

[0084] In some embodiments, the adapter assembly 18 is connected to the mounting plate 22 by welding.

[0085] In this way, the connection between the adapter assembly 18 and the mounting plate 22 can be made secure.

[0086] Specifically, the connection formed by welding the adapter component 18 to the mounting plate 22 is continuous, which makes the connection between the adapter component 18 and the mounting plate 22 firm and reduces the deformation of the mounting plate 22.

[0087] In some implementations, please refer to Figure 4 and Figures 5 to 9 The air duct assembly 14 includes an air inlet section 36, a middle section 37 and an air outlet section 38 connected in sequence. Cold air enters through the air inlet section 36 and flows through the middle section 37, and flows out from the air outlet section 38 and toward the battery module 13 to dissipate heat.

[0088] Along the direction of cold air flow, the air duct assembly 14 includes a first mounting side plate 42 disposed in the middle section 37 and a second mounting side plate 44 disposed in the air outlet section 38. The first mounting side plate 42 is gradually inclined in a direction away from the central axis L of the air duct assembly 14, and the second mounting side plate 44 is parallel to the central axis L of the air duct assembly 14.

[0089] This increases the air outlet area of ​​the air duct assembly 14 and improves the heat dissipation uniformity of the battery module 13.

[0090] Specifically, cold air enters the intermediate section 37 through the air inlet section 36. Because the first mounting side plate 42 gradually tilts away from the central axis L of the air duct assembly 14, the air duct area within the intermediate section 37 gradually increases outwards, thereby increasing the outlet area of ​​the cold air. The cold air can then be blown out through the air outlet section 38 and directed towards the battery modules 13, allowing more battery modules 13 to be cooled. This improves the uniformity of heat dissipation in the battery modules 13 and reduces the temperature difference between different parts of each battery module 13.

[0091] In some embodiments, the adapter assembly 18 includes a first mounting plate 46, a second mounting plate 48, and a third mounting plate 50. The first mounting plate 46 is detachably connected to the first mounting side plate 42 and the second mounting plate 48, and the second mounting plate 48 is fixedly connected to the mounting plate 22. The third mounting plate 50 is detachably connected to the second mounting side plate 44, and the third mounting plate 50 is fixedly connected to the mounting plate 22.

[0092] In this way, the air duct assembly 14 can be installed more stably on the mounting plate 22.

[0093] Specifically, the air inlet section 36 can be connected to the air outlet of the air conditioning component 34. The air inlet section 36 guides the cold air blown out of the air outlet of the air conditioning component 34 to the middle section 37. The air outlet section 38 has an air outlet 52 at the rear of its bottom surface, through which the cold air is blown towards the battery cluster 24.

[0094] The air duct assembly 14 is connected to the adapter assembly 18 on both sides by two mounting side plates so that the air duct assembly 14 can be better supported.

[0095] When installing the air duct assembly 14, with the air duct assembly 14 as the main body, the third disassembly plate 50 and the first disassembly plate 46 are detachably installed on the second mounting side plate 44 and the first mounting side plate 42 of the air duct assembly 14, respectively. During installation, the first disassembly plate 46 and the third disassembly plate 50 can maintain an installation gap of 2-3mm with the mounting side plates. This gap can be positioned by using a shim. After the third disassembly plate 50 and the second disassembly plate 48 are fixedly connected to the top mounting plate 22 inside the accommodating chamber 12, the shim can be removed. Then, the second disassembly plate 48 and the first disassembly plate 46 are detachably connected together. Thus, the air duct assembly 14, the first disassembly plate 46, the second disassembly plate 48, and the third disassembly plate 50 are connected together to form a whole. This whole is then installed and fixed on the mounting plate 22 inside the accommodating chamber 12 (e.g., Figure 4 (As shown). The reason for positioning the entire assembly within the housing 12 is that the space within the housing 12 is relatively large, and the air duct assembly, air conditioning component 34, and cluster rack 84 all have relative installation positions. This positioning can greatly reduce the installation error of the air duct assembly. The air duct assembly may include air duct component 14 and adapter component 18.

[0096] The third disassembly plate 50 and the second disassembly plate 48 can be welded together with the mounting plate 22 on the top of the accommodating compartment 12. Since the mounting plate 22 itself is relatively thin, it will deform when bearing a certain weight of the air duct assembly 14. When the third disassembly plate 50 and the second disassembly plate 48 are welded to the mounting plate 22, the connection with the mounting plate 22 is continuous, thereby increasing the rigidity of the mounting plate 22 and preventing the mounting plate 22 from collapsing due to the weight, which would cause the position of the air duct assembly 14 to change.

[0097] When through holes are required for installation, because the mounting plates 22 inside the accommodating compartment 12 are assembled piece by piece, if through holes are pre-drilled on the mounting plates 22 and nuts are installed, when the through holes are distributed on two mounting plates 22, the assembly of the mounting plates 22 will produce assembly errors, causing the overall hole positions to be unable to align with the mounting through holes on the air duct assembly 14, making installation impossible. If multiple mounting plates 22 have the same problem, the positional relationship between the air duct assembly 14, the air conditioning assembly 34, and the cluster frame 84 cannot be guaranteed. To solve this problem, the second disassembly plate 48 is welded onto the mounting plate 22 as an adapter plate (using the method described above to position and install the air duct assembly 14 as a whole). This ensures the accurate positioning of the air duct assembly 14, allows the holes of the first disassembly plate 46 and the second disassembly plate 48 to align, and increases the rigidity of the top mounting plate 22, increasing its load-bearing capacity, thereby allowing the air duct assembly 14 to be installed more stably on the mounting plate 22.

[0098] In some embodiments, the first mounting side plate 42 has a first connecting portion 54, and the first detachable plate 46 has a second connecting portion 55. The first detachable plate 46 and the first mounting side plate 42 are detachably connected by a first fastener 56 passing through the first connecting portion 54 and the second connecting portion 55.

[0099] This facilitates the assembly and disassembly of the air duct assembly 14.

[0100] Specifically, in Figure 9 In this embodiment, the first connecting part 54 is a nut, the first fastener 56 is a bolt, and the second connecting part 55 includes a through hole. The first connecting part 54 can be welded and fixed to the first mounting side plate 42 firstly, and then the first fastener 56 passes through the second connecting part 55 and is threadedly connected to the first connecting part 54, thereby allowing for the detachable connection of the first disassembly plate 46 and the air duct assembly 14. During disassembly, the first fastener 56 is removed, allowing the air duct assembly 14 to be separated from the first disassembly plate 46. Preferably, there are multiple first connecting parts 54, first fasteners 56, and second connecting parts 55, which correspond one-to-one and are arranged along a straight line.

[0101] In other embodiments, the first connecting portion 54 may have a threaded hole in the first mounting side plate 42, and the first fastener 56 may be a bolt, which engages with the thread of the first connecting portion 54 without requiring a nut. Alternatively, the first connecting portion 54 may be a through hole, and the first fastener 56 may include a bolt and a nut that engage through the through hole for a detachable connection.

[0102] It is understood that in other embodiments, the first connecting part 54 is not limited to a nut, but may also include a fixing hole opened on the first mounting side plate 42, or a snap fastener. The first fastener 56 is not limited to a bolt, but may also be a pin, a mounting post, or a fastening member that is detachably connected to the snap fastener, and is not specifically limited here.

[0103] In some embodiments, the first mounting plate 46 is provided with a first mounting hole 68, and the second mounting plate 48 is provided with a second mounting hole 70. The first mounting plate 46 and the second mounting plate 48 are detachably connected by a second fastener 73 passing through the first mounting hole 68 and the second mounting hole 70.

[0104] This improves the assembly efficiency of the first disassembly plate 46 and the second disassembly plate 48.

[0105] Specifically, both the first disassembly plate 46 and the second disassembly plate 48 are provided with mounting holes. The second fastener 73 may include bolts and nuts. The mounting holes are provided mainly to allow for a slightly larger mounting hole when the bolts and nuts pass through the mounting hole for connection, so as to reserve assembly allowance. This eliminates the need for extremely high operating precision by assembly personnel, making the operation relatively simple and improving assembly efficiency.

[0106] In some implementations, please refer to Figures 10 to 15 The first detachable plate 46 includes a first sub-plate 60 and a second sub-plate 62 that are vertically connected. The first sub-plate 60 is detachably connected to the first mounting side plate 42. The second detachable plate 48 includes a base plate 64 that is perpendicular to each other and two support plates 66. The two support plates 66 are connected to the two sides of the base plate 64 in the width direction. The base plate 64 is detachably connected to the second sub-plate 62. The two support plates 66 are fixedly connected to the mounting plate 22.

[0107] This ensures that the air duct assembly 14 is installed in the correct position.

[0108] Specifically, in one embodiment, the first sub-plate 60 has a second connecting portion 54, the second sub-plate 62 has a first mounting hole 68, the first mounting side plate 42 has a first connecting portion 54 (such as a nut), and the base plate 64 has a second mounting hole 70. A nut of a second fastener 73 is welded to the second mounting hole 70. The first fastener 56 can be used to pass through the second connecting portion 55 and connect to the first connecting portion 54 to connect the first detachable plate 46 to the air duct assembly 14. At this time, the first sub-plate 60 and the first mounting side plate 42 can be clearance-fitted, i.e., the first fastener 56 is not tightened. Then, the bolt of the second fastener 73 is used to pass through the first mounting hole 68 and the second mounting hole 70 and connect to the nut of the third fastener 73 on the base plate 64, thereby making the first detachable plate 46 and the second detachable plate 48 detachably connected. Figure 10 and Figure 11In the illustrated embodiment, both the through hole of the second connecting portion 55 and the first mounting hole 68 are slot-shaped holes. This facilitates adjusting the alignment of the second connecting portion 55 with the first connecting portion 54 on the air duct assembly 14, and also facilitates adjusting the alignment of the first mounting hole 68 with the nut of the third fastener 73. Preferably, there are multiple second fasteners 73, first mounting holes 68, and second mounting holes 70, which correspond one-to-one and are arranged along a straight line.

[0109] Next, the second disassembly plate 48 is fixed to the mounting plate 22 by two support plates 66. For example, the two support plates 66 can be fixed to the mounting plate 22 by welding. Then, the first fastener 56 on the first sub-plate 60 is tightened to secure the first disassembly plate 46 to the air duct assembly 14. In the above installation process, the first sub-plate 60 and the first mounting side plate 42 are first connected with a gap, and then the first disassembly plate 46 and the second disassembly plate 48 are fixedly connected. This allows the first disassembly plate 46 and the second disassembly plate 48 to be pre-installed on the air duct assembly 14 to form a whole. This whole is connected to the mounting plate 22 by the fixed connection between the second disassembly plate 48 and the mounting plate 22, realizing the pre-positioning of the air duct assembly 14. Then, the first sub-plate 60 and the first mounting side plate 42 are tightened to achieve the final positioning of the air duct assembly 14, which can ensure the accurate installation position of the air duct assembly 14.

[0110] Please refer to Figure 16 In other embodiments, the two support plates 66 are vertically and horizontally extended flanges, and the flanges are surface-connected to the mounting plate 22 to enhance the connection strength and reliability.

[0111] In some embodiments, the second mounting side plate 44 is provided with a third connecting portion 74, and the third detachable plate 50 is provided with a fourth connecting portion 78. The third detachable plate 50 and the second mounting side plate 44 are detachably connected by a third fastener 76 passing through the third connecting portion 74 and the fourth connecting portion 78.

[0112] This facilitates the assembly and disassembly of the air duct assembly 14.

[0113] Specifically, in Figure 9 In this embodiment, the third connecting part 74 is a nut, the third fastener 76 is a bolt, and the fourth connecting part 78 includes a through hole (see...). Figure 9 and Figures 17 to 19The third connecting part 74 can be welded and fixed to the second mounting side plate 44 first. Then, the fourth connecting part 78 is threaded through the third fastener 76 and connected to the third connecting part 74, thereby allowing for the detachable connection of the third disassembly plate 50 and the air duct assembly 14. For disassembly, the third fastener 76 is removed, allowing the air duct assembly 14 to be separated from the third disassembly plate 50. Preferably, there are multiple third connecting parts 74, third fasteners 76, and fourth connecting parts 78, which correspond one-to-one and are arranged along a straight line.

[0114] In other embodiments, the third connecting portion 74 may be formed in a threaded hole on the second mounting side plate 44, and the third fastener 76 may be a bolt, which engages with the thread of the third connecting portion 74 without requiring a nut. Alternatively, the third connecting portion 74 may be a through hole, and the third fastener 76 may include a bolt and nut that engage through the through hole for a detachable connection.

[0115] It is understood that in other embodiments, the third connecting part 74 is not limited to a nut, but may also include a fixing hole opened on the second mounting side plate 44, or a snap fastener. The third fastener 76 is not limited to a bolt, but may also be a pin, a mounting post, or a fastening member that is detachably connected to the snap fastener, and is not specifically limited here.

[0116] exist Figures 17 to 19 In the embodiment shown, the third disassembly plate 50 has a similar structure to the first disassembly plate 46, and the height of the top edge of the third disassembly plate 50 is basically the same as the height of the top edge of the second disassembly plate 48.

[0117] exist Figure 17 In the embodiment shown, the through hole of the fourth connecting part 78 is a slot-shaped hole, which facilitates the adjustment of the alignment position of the fourth connecting part 78 and the third connecting part 74 on the air duct assembly.

[0118] In some embodiments, the first mounting side plate 42 and the second mounting side plate 44 are provided with a fixed mounting part 80 and an adjustable mounting part 82 arranged in a vertical direction. The adjustable mounting part 82 is located below the fixed mounting part 80. The first connecting part 54 is either the fixed mounting part 80 or the adjustable mounting part 82, and the third connecting part 74 is either the fixed mounting part 80 or the adjustable mounting part 82.

[0119] This facilitates the maintenance or replacement of the cluster frame 84.

[0120] Specifically, a cluster rack 84 is provided within the accommodating space 20, and the air duct assembly 14 is located above the cluster rack 84. When the cluster rack 84 needs maintenance or replacement, it needs to be lifted upwards and removed from the accommodating compartment 12. Therefore, the height of the air duct assembly 14 is increased by adjusting the mounting portion 82. Specifically, during normal use, the first connecting portion 54 and the third connecting portion 74 are fixed mounting portions 80, and the air duct assembly 14 is positioned low, close to the cluster rack 84. When the cluster rack 84 needs maintenance or replacement, the first connecting portion 54 and the third connecting portion 74 are adjusted mounting portions 82, and the air duct assembly 14 is positioned higher, increasing the vertical movement space of the cluster rack 84 and facilitating its maintenance or replacement.

[0121] In some embodiments, when both the first connecting part 54 and the third connecting part 74 are fixed mounting parts 80, the air duct assembly 14 is located in the first position; when both the first connecting part 54 and the third connecting part 74 are adjustable mounting parts 82, the air duct assembly is located in the second position; wherein, the height of the first position is lower than the height of the second position.

[0122] In this way, the height of the air duct assembly 14 can be adjusted.

[0123] Specifically, the adapter 18 detachably connects the first connecting part 54 and the third connecting part 74. When both the first connecting part 54 and the third connecting part 74 are adjusted, the position of the air duct assembly 14 corresponding to the mounting part 82 is the second position. When both the first connecting part 54 and the third connecting part 74 are fixed, the position of the air duct assembly 14 corresponding to the mounting part 80 is the first position. The height of the first position is lower than the height of the second position, so that in the second position, the distance between the air duct assembly 14 and the cluster frame 84 is greater than the distance between the air duct assembly 14 and the cluster frame 84 in the first position. Therefore, when the air duct assembly 14 is in the second position, the vertical movement space of the cluster frame 84 is increased, which facilitates the maintenance or replacement of the cluster frame 84.

[0124] In some embodiments, the bottom of the accommodating space 20 is provided with a substrate 83, and the energy storage system 100 also includes a cluster frame 84, which is disposed on the substrate 83 and located below the air duct assembly 14. The edge of the substrate 83 of the accommodating space 20 is provided with a baffle 86.

[0125] Please refer to Figure 4 The energy storage system 100 meets the following conditions:

[0126] H2+H3>H1, where H1 represents the height of the baffle 86 protruding relative to the substrate 83, H2 represents the vertical distance between the air duct assembly 14 and the cluster frame 84 when the air duct assembly 14 is in the first position, and H3 represents the vertical distance between the fixed mounting part 80 and the adjustable mounting part 82.

[0127] This further enhances the ease of maintenance or replacement of the cluster frame 84.

[0128] Specifically, under normal operating conditions, both the first connecting part 54 and the third connecting part 74 are fixed mounting parts 80, connected to the adapter assembly 18. Figure 9 In this embodiment, the third detachable plate 50 is detachably connected to the air duct assembly 14 via the connection of the third fastener 76 and the fixed mounting portion 80, and the first detachable plate 46 is detachably connected to the air duct assembly 14 via the connection of the first fastener 56 and the fixed mounting portion 80. Both the first connecting portion 54 and the third connecting portion 74 may include nuts, and both the first fastener 56 and the third fastener 76 may include bolts.

[0129] In the maintenance or replacement state, both the first connecting part 54 and the third connecting part 74 are adjustable mounting parts 82, connected to the adapter assembly 18. The third mounting plate 50 is detachably connected to the air duct assembly 14 via the connection of the third fastener 76 and the adjustable mounting part 82, and the first mounting plate 46 is detachably connected to the air duct assembly 14 via the connection of the first fastener 56 and the adjustable mounting part 82.

[0130] The baffle 86 is a protrusion formed by the lower crossbeam of the door frame 30. When the cluster frame 84 needs to be lifted out of the housing 12 for maintenance or replacement, first disassemble the connection between the first connecting part 54 and the first fastener 56, and the connection between the third connecting part 74 and the third fastener 76, for example, remove the fixing bolts of the originally connected air duct assembly 14. Move the air duct assembly 14 vertically upwards to a certain height, raise the air duct assembly 14 to the point where the adjusting mounting part 82 on the first mounting side plate 42 overlaps with the second connecting part 55, and the adjusting mounting part 82 on the second mounting side plate 44 overlaps with the fourth connecting part 78. Lock the adapter assembly 18 at the two adjusting mounting parts 82 to raise the height of the air duct assembly 14, making room for the cluster frame 84 to be raised first. Figure 4 The height H1 shown is level with or slightly above the threshold, and then raised outwards. Since the vertical upward height H4 of the air duct assembly 14 is equal to the vertical distance H3 between the fixed mounting part 80 and the adjusting mounting part 82, and the distance between the top of the cluster frame 84 and the air duct assembly 14 is H2, and H2+H3>H1, the cluster frame 84 can be raised out smoothly. In this embodiment, when the cluster frame 84 is maintained or replaced, it is not necessary to raise the entire air duct assembly 14; simply moving the air duct assembly 14 upwards is sufficient.

[0131] In one implementation, please refer to Figures 5 to 9 The air duct assembly also includes an air duct adapter 92. The air duct assembly 14 is detachably connected to the air duct adapter 92. When moving the air duct assembly 14 upward, the air duct adapter 92 needs to be removed.

[0132] In some embodiments, the side panel of the accommodating compartment 12 is provided with a door frame 30, and the energy storage system 100 satisfies the following conditions:

[0133] W1>W2, where W1 represents the width of the door frame 30 and W2 represents the width of the air duct assembly 14.

[0134] In this way, the air duct assembly 14 can be easily moved out of the housing 12.

[0135] Specifically, since the energy storage system 100 satisfies the condition W1>W2, when it is necessary to move the air duct assembly 14 outside the housing 12 for maintenance, the bolts on the air duct assembly 14 are removed, and it is lowered a certain height so that the upper end of the air duct assembly 14 is slightly lower than the upper crossbeam of the door frame 30, allowing it to be lifted out directly. Figure 3 As shown, there is no obstruction in the width direction. When removing the air duct assembly 14, it is not necessary to erect the air duct assembly 14 to remove it from the housing 12, thus making it convenient to remove the air duct assembly 14 from the housing 12.

[0136] In some embodiments, the energy storage system 100 includes an air conditioning component 34 and an air duct adapter 92. The air conditioning component 34 is provided with an air outlet. The air duct adapter 92 connects the air inlet section 36 and the air outlet, and the connection between the air duct adapter 92 and the air duct component 14 is detachable.

[0137] In this way, the positions of the air conditioning component 34 and the air duct component 14 can be adapted.

[0138] Specifically, in Figure 4 In the embodiment shown, the air outlet of the air conditioning component 34 is located on the upper half of the inner side of the air conditioning component 34. The air duct component 14 is installed on the mounting plate 22 at the top of the accommodating space 20. The air duct component 14 is at a higher position, and the air outlet is at a lower position. One end of the air duct adapter 92 is lower, and the other end is higher. The lower end is connected to the air outlet, and the higher end is connected to the air inlet section 36. Therefore, the air inlet section 36 and the air outlet of different heights can be connected through the air duct adapter 92, so that the cold air of the air conditioning component 34 can smoothly enter the air duct component 14.

[0139] The connection between the air duct adapter 92 and the air inlet section 36 is detachable. When the air duct assembly 14 needs to be moved out of the housing 12 as a whole, the air inlet section 36 and the air duct adapter 92 can be detached to avoid moving too many parts.

[0140] exist Figure 1 and Figure 2In the illustrated embodiment, multiple rows of battery clusters 24 are arranged in the accommodating space 20 along the left-right direction. The energy storage system 100 includes multiple door frames 30, each door frame 30 corresponding to the position of one battery cluster 24. A door body 32 is installed on the door frame 30, and an air conditioning component 34 can be installed on the outer side of the door body 32. When maintenance of the energy storage system 100 is required, the door body 32 can be opened. If it is necessary to move the cluster rack 84 out of the accommodating compartment 12, firstly, the fixed mounting part 80 of the air duct assembly 14 is removed from the adapter assembly 18, then moved upward to a certain height, and then the adjusting mounting part 82 of the air duct assembly 14 is connected to the adapter assembly 18, and then the cluster rack 84 is lifted outward.

[0141] When it is necessary to move the air duct assembly 14 out of the housing 12, after removing the bolts on the air duct assembly 14, lower it to a certain height so that the upper end of the air duct assembly 14 is slightly lower than the upper crossbeam of the door frame 30, and then the air duct assembly 14 can be lifted out directly.

[0142] In summary, in the energy storage system 100 of the present invention, the air duct assembly 14 is easy to disassemble, maintain and replace, the air duct assembly 14 is accurately positioned, the deformation of the top mounting plate 22 of the air duct assembly 14 is reduced, and the cluster frame 84 can be lifted out of the housing 12 from the side door for maintenance or replacement.
