Description

Technical Field

[0001] This application relates to the technical field of energy storage devices, specifically to a partition board for an energy storage container and an energy storage container. Background Art

[0002] An energy storage container is an enclosed container integrating energy storage batteries, a battery management system (BMS ， Battery Management System), an energy conversion system and other devices; it is an efficient, flexible and reliable energy storage device with broad application prospects in multiple fields such as power construction, emergency power supply, and grid connection of renewable energy. With the continuous progress of technology and the continuous expansion of the market, the development prospect of energy storage containers will be even broader.

[0003] In related technologies, multiple side-by-side partition boards are usually used inside an energy storage container to divide the energy storage container into multiple energy storage units. Multiple batteries are stored in each energy storage unit. The partition boards are usually made of heat-insulating and high-temperature-resistant materials to insulate heat and fire between each energy storage unit, so as to improve the independent safety of each energy storage unit, and can avoid a fire caused by high temperature in a certain energy storage unit inside the energy storage container, thereby igniting other energy storage units and causing more economic losses.

[0004] However, the existing partition boards are usually made of a single material. Although their theoretical heat-insulating performance meets the requirements, in actual application, when a fire occurs in the battery, a high-temperature environment is usually generated, which will cause the partition boards to deform and collapse, and thus they cannot insulate heat and fire. Summary of the Utility Model

[0005] In view of this, this application provides a partition board for an energy storage container and an energy storage container to solve or improve the problems of deformation and collapse of the partition board for an energy storage container.

[0006] On the one hand, this application provides a partition board for an energy storage container, including a partition board body. The partition board body includes a frame, a partition board base layer and a skin layer; the partition board base layer is a heat-insulating and fire-resistant layer, and the partition board base layer is filled and arranged inside the frame; the skin layer covers the outer surface of the frame, and the skin layer is a heat-resistant layer.

[0007] By filling the partition board base layer inside the frame and covering the outer surface of the frame with the skin layer, since the partition board base layer is a heat-insulating and fire-resistant layer and the skin layer is a heat-resistant layer, the partition board base layer can be fixed under the support of the frame and the wrapping of the skin layer, so that the partition board body has a high anti-deformation ability, thereby preventing the partition board for an energy storage container from deforming and collapsing.

[0008] In an alternative embodiment, the skin layer is a heat-resistant metal plate layer; and / or, the frame is a heat-resistant metal frame body.

[0009] In an alternative embodiment, the skin layer includes a first covering sheet and a second covering sheet. The outer surface of the frame includes a first outer surface, a circumferential surface, and a second outer surface. The first outer surface and the second outer surface are oppositely arranged along the thickness direction of the frame. The two ends of the circumferential surface are respectively connected to the edge of the first outer surface and the edge of the second outer surface. The first covering sheet covers the first outer surface, the circumferential surface, and the edge part of the second outer surface. The second covering sheet covers the second outer surface.

[0010] In an alternative embodiment, a reinforcing beam is provided in the middle of the frame, and a process hole is provided at the position of the skin layer corresponding to the reinforcing beam. The skin layer is riveted or welded to the reinforcing beam through the process hole; and / or, the thickness of the partition body is 15 mm to 300 mm.

[0011] In an alternative embodiment, the partition base layer at least includes any one of a rock wool layer, an aerogel felt layer, a high silica glass fiber layer, a ceramic fiber layer, a melamine heat-insulating cotton layer, an acrylic heat-insulating cotton layer, a glass fiber layer, a glass wool layer, an asbestos layer, a slag wool layer, a hard calcium silicate type calcium silicate heat-insulating board layer, a lightweight clay brick layer, a lightweight silica brick layer, a aluminum silicate fiber layer, a lightweight high-aluminum brick layer, a polycrystalline alumina fiber layer, an alumina hollow sphere layer, a lightweight corundum brick layer, a zirconia fiber layer, a zirconia hollow sphere layer, and a multi-winner heat plate layer along the thickness direction of the frame.

[0012] On the other hand, the present application also provides an energy storage container, including a prefabricated cabin body, a battery rack, and an energy storage container partition board in any one of the above embodiments; the battery rack is arranged in the prefabricated cabin body; a plurality of energy storage container partition boards are provided, and the plurality of energy storage container partition boards are arranged on the battery rack at intervals along the length direction of the prefabricated cabin body. A battery pack is placed between any two adjacent energy storage container partition boards.

[0013] Since the energy storage container includes the energy storage container partition board and has the same effect as the energy storage container partition board, it will not be elaborated here; in addition, a plurality of energy storage container partition boards are arranged at intervals along the length direction of the prefabricated cabin body, dividing the prefabricated cabin body into multiple spaces. When thermal runaway occurs, or even when a fire breaks out, the flame will not directly burn the batteries in the adjacent spaces, playing the role of a firewall and blocking the flame.

[0014] In an alternative embodiment, a plurality of the partition bodies are spaced apart from the inner top surface of the prefabricated cabin to form an avoidance passage above the partition; a plurality of the partition bodies are spaced apart from the inner bottom surface of the prefabricated cabin to form an avoidance passage below the partition.

[0015] By arranging a plurality of partition bodies to be spaced apart from the inner top surface of the prefabricated cabin, an avoidance passage above the partition is formed at the inner top of the prefabricated cabin, which can be used to arrange integral fire-fighting components, such as water fire pipes, fire communication lines, and fire agent spraying pipelines; by arranging a plurality of partition bodies to be spaced apart from the inner bottom surface of the prefabricated cabin, an avoidance passage below the partition can be formed at the inner bottom of the prefabricated cabin to arrange components such as cable trough racks and liquid cooling pipes, and the high and low voltage wires of the prefabricated cabin are arranged in the cable trough rack, which makes full use of the space at the inner bottom of the prefabricated cabin without occupying the space for battery pack arrangement.

[0016] In an alternative embodiment, an exhaust window is provided at the top of the side surface of the prefabricated cabin; a ventilation window is provided at the bottom of the prefabricated cabin and / or at the bottom of the side surface of the prefabricated cabin.

[0017] By providing an exhaust window at the top of the side surface of the prefabricated cabin and a ventilation window at the bottom of the prefabricated cabin and / or at the bottom of the side surface of the prefabricated cabin, when the energy storage container is operating normally, the natural wind from the outside enters the prefabricated cabin through the ventilation window from the bottom or the side bottom of the prefabricated cabin and enters the storage spaces of each battery pack respectively to perform ventilation regularly, and the collected combustible gas is discharged from the ventilation window on the prefabricated cabin, avoiding the accumulation of combustible gas in the prefabricated cabin, thereby improving the safety of the prefabricated cabin.

[0018] In an alternative embodiment, a pressure relief window is provided at the top of the prefabricated cabin; and / or, a pressure relief window is provided at the top of the side surface of the prefabricated cabin; and / or, a cabin door is provided on one side surface of the prefabricated cabin along its width direction.

[0019] With the setting of the pressure relief window, when a thermal runaway occurs in the battery pack in the prefabricated cabin, the fire agent conducts fire-fighting on the battery pack through the water fire pipe and the fire agent spraying pipeline located in the avoidance passage above the partition, and at the same time, a large amount of combustible gas generated by the battery pack quickly discharges from the top of the prefabricated cabin and / or the pressure relief window on the side of the prefabricated cabin through the avoidance passage above the partition at the inner top of the prefabricated cabin, avoiding accumulation, preventing the occurrence of explosion and deflagration problems in the energy storage prefabricated cabin, and improving the safety of the energy storage prefabricated cabin.

[0020] The hatch is arranged on one side of the prefabricated cabin along its width direction. All battery packs inside the prefabricated cabin are assembled and disassembled through this hatch, avoiding the problem that multiple doors in the battery compartment of the prefabricated cabin occupy a large amount of space, so as to arrange more battery packs in the prefabricated cabin and improve the volume energy density of the energy storage container.

[0021] In an alternative embodiment, the battery rack includes a top beam, a bottom beam and vertical beams. There are multiple vertical beams, and the multiple vertical beams are arranged in a rectangular array and extend along the height direction of the prefabricated cabin. The tops of the multiple vertical beams are fixedly connected to the top beam, and the bottoms of the multiple vertical beams are all connected to the bottom beam. An energy storage container partition board is arranged between any two adjacent vertical beams along the width direction of the prefabricated cabin. Multiple slide rail groups are arranged on any two adjacent rows of vertical beams along the length direction of the prefabricated cabin. The multiple slide rail groups are spaced along the height direction of the prefabricated cabin, and the slide rail groups are used to hold the battery packs.

[0022] By arranging the energy storage container partition board between two adjacent vertical beams along the width direction of the prefabricated cabin, so that the energy storage container partition board and the vertical beam overlap along the width direction of the prefabricated cabin, the occupied space of the energy storage container partition board can be reduced, and the volume energy density of the energy storage container can be further improved.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0046] In the related art, inside the energy storage container 200, multiple side-by-side partition plates are usually used to divide the energy storage container 200 into multiple energy storage units. Multiple batteries are stored in each energy storage unit. The partition plates are usually made of heat-insulating and high-temperature-resistant materials to insulate heat and fire between the energy storage units, so as to improve the independent safety of each energy storage unit and avoid the fire caused by high temperature in a certain energy storage unit inside the energy storage container 200 from igniting other energy storage units and causing more economic losses. However, the existing partition plates are usually made of a single material. Although their theoretical heat-insulating performance meets the requirements, in actual application, when a battery catches fire, a high-temperature environment is usually generated, which will cause the partition plates to deform and collapse, and thus they cannot insulate heat and fire.

[0047] To solve the above problems, this application provides an energy storage container partition plate 100 and an energy storage container 200, which can solve the problems of deformation and collapse of the energy storage container partition plate 100.

[0048] The following combines Figures 1 to 10 to describe the embodiments of this application.

[0049] According to the embodiments of this application, on the one hand, an energy storage container partition plate 100 is provided. As shown in Figure 1 and Figure 2 , it includes a partition plate body 10. The partition plate body 10 includes a frame 101, a partition plate base layer 102, and a skin layer 103. The partition plate base layer 102 is a heat-insulating and fire-resistant layer. The partition plate base layer 102 is filled in the frame 101 to form a partition plate unit (that is, the partition plate unit includes the partition plate base layer 102 and the frame 101). The skin layer 103 covers the outer surface of the partition plate unit, and the skin layer 103 is a heat-resistant layer.

[0050] It should be noted that the frame 101 can be any form of frame, such as a mesh, a square box with a reinforcing beam 1011, etc., as long as it can strengthen the strength of the partition plate body 10.

[0051] It is worth noting that as shown in Figure 1 , in the thickness direction of the frame 101, it usually refers to the vertical direction of the largest surface on the frame 101. If the partition plate body 10 is a rectangular plate, the vertical direction of the largest surface on the rectangular plate is its thickness direction.

[0052] In addition, it should be noted that, as Figure 9 shown, the length direction, width direction and thickness direction of the prefabricated cabin body 20 are as Figure 9 shown.

[0053] In this embodiment, by filling the partition base layer 102 in the frame 101 and covering the outer surfaces of the frame 101 and the partition base layer 102 with the skin layer 103, since the partition base layer 102 is a heat-insulating and fire-resistant layer and the skin layer 103 is a heat-resistant layer, the partition base layer 102 can be fixed under the support of the frame 101 and the wrapping of the high-strength skin layer 103, so that the partition body 10 has a high anti-deformation ability, thereby preventing the deformation and collapse of the energy storage container partition board 100.

[0054] In a specific embodiment, the skin layer 103 is a high-temperature-resistant metal plate layer, specifically, any one of an aluminum plate layer, an iron plate layer, an aluminum alloy plate layer, etc. More specifically, steel material plates such as SPCC, Q235, SPA-H, etc. can be used, with a thickness of 0.8 mm to 4 mm, preferably any one of 0.8 mm, 1 mm, 2 mm, 3 mm, 4 mm; and / or, the frame 101 is a high-temperature-resistant metal plate frame body, specifically, aluminum plates, iron plates, aluminum alloys, etc. More specifically, steel material plates such as SPCC, Q235, SPA-H, etc. can be used, with a thickness of 0.8 mm to 1 mm, preferably any one of 0.8 mm, 0.9 mm, 1.0 mm; in this embodiment, the skin layer 103 is a high-temperature-resistant metal plate layer with high strength, which can effectively strengthen the strength of the partition body 10, and the material is cheap; the frame 101 is a high-temperature-resistant metal frame body with high strength, cheap price and convenient production.

As Figure 3As shown, the first cladding sheet 1031 clads the edge parts of the first outer surface 1012, the first surface, the circumferential surface 1013, and the second outer surface 1014, and the second cladding sheet 1032 clads the second outer surface 1014 and the second surface.

[0056] It should be noted that the circumferential surface 1013 is an annular surface. If the skin layer 103 is in the shape of a rectangular cavity, the circumferential surface 1013 is a rectangular ring. Of course, according to the shape of the skin layer 103, it can be in a polygonal shape or other states.

[0057] It should be noted that the first cladding sheet 1031 and the second cladding sheet 1032 are made of the same material, specifically steel material plates such as SPCC, Q235, and SPA-H.

[0058] In this embodiment, the first cladding sheet 1031 wraps the edge parts of the first outer surface 1012, the first surface, the circumferential surface 1013, and the second outer surface 1014 of the skeleton, so that the first cladding sheet 1031 forms a flanged flange on the second outer surface 1014, thereby further strengthening the strength of the partition body 10.

[0060] In this embodiment, the skin layer 103 is riveted or welded to the reinforcing beam 1011 through the process hole 1033, which can firmly connect the skin layer 103 to the reinforcing beam 1011 on the frame 101, and the process hole 1033 is filled and shielded by rivets or welding filler metal, presenting a state without the process hole 1033 in appearance.

[0061] In one embodiment, the heat conductivity of the partition base layer 102 does not exceed 0.1 W / (m·K); specifically, the partition base layer 102 includes at least one layer of rock wool layer, aerogel felt layer, high-silica glass fiber layer, ceramic fiber layer, melamine insulation cotton layer, acrylic insulation cotton layer, glass fiber layer, glass wool layer, asbestos layer, slag wool layer, hard calcium silicate type calcium silicate insulation board layer, light clay brick layer, light silica brick layer, aluminum silicate fiber layer, light high-aluminum brick layer, polycrystalline alumina fiber layer, alumina hollow sphere layer, light corundum brick layer, zirconia fiber layer, zirconia hollow sphere layer, and multi-winner heat plate layer along the thickness direction of the frame 101.
