Technical Field

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

[0002] Energy storage power stations are equipment systems centered on electrochemical batteries or electromagnetic energy storage media. They possess the functions of cyclic energy storage, dynamic regulation, and efficient release, and are a core supporting technology for smart grids, microgrids, and renewable energy grid integration. With the low-carbon transformation of the energy structure, the strategic value of energy storage power stations in promoting the large-scale application of new energy sources, building new power systems, and ensuring the safe operation of the power grid is becoming increasingly prominent. As a result, the capacity of energy storage power stations is gradually expanding. Therefore, how to improve the reliability of energy storage power stations has become a major concern in the industry. Utility Model Content

[0003] This application provides an energy storage component and energy storage device, which aims to solve the problem of poor reliability of existing energy storage power stations.

[0004] To address the aforementioned issues, this application provides an energy storage component, comprising: an energy storage rack and a battery pack; the energy storage rack includes: a multi-layer tray and a frame surrounding the tray; at least one battery pack is disposed on the tray, and the frame has a first frame and a second frame located on opposite sides of the tray; the battery pack has an energy transmission end disposed toward the first frame and an information transmission end disposed toward the second frame; the energy transmission end is connected to a first wiring harness on the first frame, and the information transmission end is connected to a second wiring harness on the second frame.

[0005] In the above scheme, the energy transmission end and information transmission end of the battery pack are respectively positioned facing the first frame and the second frame, and connected to the first wiring harness and the second wiring harness on the first frame and the second frame, respectively. The first frame and the second frame are located on opposite sides of the support plate carrying the battery pack, allowing the first and second wiring harnesses to be laid out on opposite sides of the battery pack, each with more ample space for wiring. This not only improves the flexibility, convenience, and safety of the wiring of the first and second wiring harnesses, but also reduces the probability of mutual interference between the first and second wiring harnesses, thereby improving the operational reliability of the energy storage component.

[0006] In one embodiment, the first frame has a first wire groove for accommodating a first wire harness, and the second frame has a second wire groove for accommodating a second wire harness.

[0007] Therefore, by setting up a first wire trough to accommodate the first wire harness and a second wire trough to accommodate the second wire harness, it helps to improve the wiring convenience and neatness of the first and second wire harnesses.

[0008] In one embodiment, the energy transmission terminal includes a positive electrode assembly and a negative electrode assembly; the first wiring harness includes a positive electrode trace connected to the positive electrode assembly and a negative electrode trace connected to the negative electrode assembly.

[0009] Therefore, by setting the energy transmission end of the battery pack to have a positive electrode assembly and a negative electrode assembly, and the first wiring harness having a positive electrode line connecting the positive electrode assembly and a negative electrode line connecting the negative electrode assembly, the battery pack can be connected to an external high-voltage device for charging and discharging through the first wiring harness, thereby realizing energy transmission between the battery pack and the high-voltage device.

[0010] In one embodiment, the first cable tray includes: two first main cable trays and multiple first branch cable trays; the two first main cable trays are spaced apart, and the multiple first branch cable trays are all connected to the two first main cable trays; the number of first branch cable trays is the same as the number of layers of the tray, and each branch cable tray corresponds to a multi-layer tray; the positive electrode cable and the negative electrode cable are respectively located in the two first main cable trays, and only one of the positive electrode cable and the negative electrode cable is located in the same first main cable tray; one end of the positive electrode cable and the negative electrode cable are both located in the first branch cable tray and are respectively connected to the positive electrode assembly and the negative electrode assembly.

[0011] Therefore, by setting the positive and negative wires in two spaced-apart first main wire slots, with only one of the positive and negative wires in the same first main wire slot, and one end of each positive and negative wire being located in a first branch wire slot and connected to the positive and negative assemblies respectively, the positive and negative wires can be routed alternately after being connected to the positive and negative assemblies. This helps to improve the routing convenience and neatness of the first wire harness.

[0012] In one embodiment, the information transmission end includes: at least one information transmission interface; the second wiring harness includes: an information transmission line connected to the information transmission interface.

[0013] Therefore, by setting the information transmission end of the battery pack to have at least one information transmission interface, and the second wiring harness to have an information transmission line connected to the information transmission interface, the battery pack can be connected to an external low-voltage device through the second wiring harness to transmit information, thereby realizing data interaction between the battery pack and the low-voltage device.

[0014] In one embodiment, the second cable tray includes: a second main cable tray and multiple second branch cable trays; the multiple second branch cable trays are all connected to the second main cable tray, the number of second branch cable trays is the same as the number of layers of the tray, and are respectively set to correspond one-to-one with the multi-layer tray; the information transmission line is located in the second main cable tray, and one end is located in the second branch cable tray and connected to the information transmission interface.

[0015] Therefore, by setting the information transmission line in the second main cable tray and one end in the second branch cable tray and connecting it to the information transmission interface, the information transmission line can be uniformly laid in the second main cable tray after being connected to the information transmission interface. This helps to improve the wiring convenience and neatness of the second cable harness.

[0016] In one embodiment, the energy transmission terminals of multiple battery packs are connected in parallel, and the information transmission terminals of multiple battery packs are connected in parallel.

[0017] Therefore, by setting the energy transmission ends of multiple battery packs in parallel and the information transmission ends of multiple battery packs in parallel, multiple battery packs can independently transmit power and exchange data. This not only improves the maintenance convenience of the battery packs, but also facilitates the expansion of capacity by increasing the number of battery packs in the future.

[0018] In one embodiment, at least one of the first and second cable trays is provided with an electromagnetic shielding layer; and / or, the first cable tray is provided with a fireproof layer.

[0019] Therefore, by providing an electromagnetic shielding layer on at least one of the first and second wire troughs, the electromagnetic radiation generated by the first wire harness can be blocked by the electromagnetic shielding layer, thereby reducing the interference of the electromagnetic radiation of the first wire harness on the information transmission of the second wire harness. At the same time, by providing a fireproof layer in the first wire trough, the first wire harness can be isolated by the fireproof layer in the event of a fire, thereby reducing the risk of fire spreading.

[0020] In one embodiment, the second frame is further provided with a plurality of liquid cooling interfaces, the same number as the plurality of battery packs; the battery pack has a liquid cooling end facing the second frame and connected to the liquid cooling interface, and the plurality of liquid cooling interfaces are provided in a one-to-one correspondence with the liquid cooling ends of the plurality of battery packs.

[0021] Therefore, by setting a liquid cooling interface on the second frame and connecting it to the liquid cooling end of the battery pack, the battery pack can be connected to an external heat dissipation device through the liquid cooling interface to achieve heat exchange between the battery pack and the heat dissipation device. At the same time, the liquid cooling interface on the second frame can also be set away from the first wiring harness to improve the isolation between the liquid cooling interface and the first wiring harness.

[0022] In one embodiment, the second frame is provided with infusion tubes connected to multiple liquid cooling interfaces and has a pipeline groove for accommodating the infusion tubes, and the infusion tubes and the second wiring harness are spaced apart.

[0023] Therefore, by setting an infusion tube and a liquid cooling interface on the second frame, the liquid cooling interface can be connected to external heat dissipation equipment through the infusion tube. At the same time, by setting a pipe groove in the second frame to accommodate the infusion tube, and by setting the infusion tube at a distance from the second wiring harness, the infusion tube can also be isolated from the second wiring harness, thereby improving the isolation between the infusion tube and the second wiring harness.

[0024] In one embodiment, the infusion tube is also provided with a plurality of valves, the same number as the plurality of liquid cooling interfaces; the plurality of valves are configured one-to-one with the plurality of liquid cooling interfaces, and the valves are used to open or close the liquid cooling interfaces.

[0025] Therefore, by installing valves on the infusion tubing, which can be used to open or close the liquid cooling interface, the liquid cooling of multiple battery packs can be kept independent, so as to facilitate the maintenance of individual battery packs.

[0026] In one embodiment, the frame is further provided with a plurality of spray heads; the plurality of spray heads are located between the first frame and the second frame, and at least one spray head is provided above each layer of tray.

[0027] Therefore, by placing the sprinkler head between the first frame and the second frame, the sprinkler head can avoid the first and second wiring harnesses. At the same time, by placing the sprinkler head above the support plate, the sprinkler head can have a larger spray range, which facilitates fire extinguishing.

[0028] In one embodiment, the tray is provided with a plurality of battery packs arranged in sequence, and the arrangement direction of the plurality of battery packs is perpendicular to the direction in which the first frame approaches or moves away from the second frame.

[0029] Therefore, by arranging the multiple battery packs on the tray in a direction perpendicular to the direction of the first frame towards or away from the second frame, the energy transmission ends of the multiple battery packs on the tray can all face the first frame, while the information transmission ends can all face the second frame, so that the multiple battery packs on the tray can be connected to the first wiring harness and the second wiring harness respectively.

[0030] This application also provides an energy storage device, which includes: a housing assembly, a high-voltage device, a low-voltage device, and the aforementioned energy storage component; the housing assembly has an accommodating space, and the high-voltage device, the low-voltage device, and the energy storage component are all disposed within the accommodating space; the high-voltage device is connected to a first wiring harness, and the low-voltage device is connected to a second wiring harness.

[0031] In the above scheme, by setting a first wiring harness to connect the energy transmission end and the high-voltage equipment, and a second wiring harness to connect the information transmission end and the low-voltage equipment, the battery pack can transmit energy to the high-voltage equipment through the first wiring harness and transmit information to the low-voltage equipment through the second wiring harness. Simultaneously, since the first and second wiring harnesses are located on the first and second frames respectively, and the first and second frames are located on opposite sides of the support plate carrying the battery pack, the first and second wiring harnesses can be arranged far apart on the frame. This helps reduce the probability of mutual interference between the first and second wiring harnesses, thereby improving the operational reliability of the energy storage components.

[0032] In one embodiment, the frame has a first side and a second side disposed opposite to each other in a first direction, and a third side and a fourth side disposed opposite to each other in a second direction, wherein the first direction and the second direction are perpendicular to each other; the first side is the side of the first frame body away from the second frame body, and the second side is the side of the second frame body away from the first frame body; the high-voltage equipment is located on the first side, and the low-voltage equipment is located on the second side; or, the high-voltage equipment is located on one of the third side and the fourth side, and the low-voltage equipment is located on the other of the third side and the fourth side; or, both the high-voltage equipment and the low-voltage equipment are located on the third side or the fourth side.

[0033] Therefore, by arranging the high-voltage equipment on the first side and the low-voltage equipment on the second side, or by placing the high-voltage and low-voltage equipment on the first and second sides respectively, or by placing both the high-voltage and low-voltage equipment on the third or fourth side, the high-voltage and low-voltage equipment can be flexibly deployed according to space requirements. Furthermore, when the high-voltage equipment is located on the first side and the low-voltage equipment on the second side, it improves the ease of connection between the high-voltage equipment and the first wiring harness, as well as the ease of connection between the low-voltage equipment and the second wiring harness.

[0034] In one embodiment, the housing assembly includes: a base, a canopy, and a middle shell; the base and the canopy are disposed opposite to each other, and the middle shell connects the base and the canopy, and together with the base and the canopy, forms an accommodating space.

[0035] Therefore, by setting up a middle shell that connects to the base and the roof respectively, and together with the base and the roof to form an enclosure space, the shell assembly can accommodate high-voltage equipment, low-voltage equipment and energy storage components, so as to protect the high-voltage equipment, low-voltage equipment and energy storage components.

[0036] In one embodiment, the middle shell includes: an outer frame and a baffle; the outer frame is detachably connected to the base and the roof, and the baffle is detachably disposed on the outer frame and together with the base and the roof, forms an accommodating space.

[0037] Therefore, by setting an outer frame connecting the base and the roof, and detachably mounting the baffle on the outer frame, which together with the base and roof encloses the accommodating space, the middle shell can be assembled with appropriate baffles and the outer frame according to environmental requirements, thereby improving the applicability of the shell assembly in different environments. Simultaneously, by setting the outer frame to be detachably connected to the base and roof, the outer frame can be decoupled from the base and roof, facilitating transportation and replacement of the outer frame, thus meeting the future expansion needs of the energy storage modules.

[0038] In one embodiment, the canopy has a flow guide surface facing away from the accommodating space, and the flow guide surface is a slope or arc surface, used to guide the fluid to flow toward the direction of the base.

[0039] Therefore, by setting the roof to have a guide surface that is away from the accommodating space, and the guide surface is a slope or arc surface, the guide surface can guide the rainwater and other fluids on the roof to flow down towards the base, thereby reducing the probability of water accumulation on the roof in rainy weather.

[0040] In one embodiment, the energy storage device further includes: a fan assembly; the fan assembly is disposed on a roof, and the roof has an air duct connecting the fan assembly and the accommodating space; the fan assembly is used to supply air into the accommodating space to create a slightly positive pressure environment in the accommodating space.

[0041] Therefore, by installing a fan assembly on the ceiling, and the ceiling having an air duct connecting the fan assembly and the housing space, the fan assembly can deliver air into the housing space through the air duct to create a slightly positive pressure environment in the housing space, which helps to reduce dust accumulation in the housing space.

[0042] In one embodiment, the air duct has multiple air outlets that connect to the accommodating space; the multiple air outlets are distributed at intervals on the ceiling and all face the frame.

[0043] Therefore, by setting the air duct to have multiple air outlets that connect the accommodating space, and all of the air outlets are set to face the frame, the airflow from the multiple air outlets can all flow to the frame. This can not only help the battery pack dissipate heat, but also reduce the accumulation of dust on the battery pack. Attached Figure Description

[0062] Energy storage containers house battery clusters for energy storage. Since these clusters typically consist of multiple battery packs, the wiring connecting them is often extensive and chaotic. For example, energy transmission lines and information transmission lines connecting the battery packs may be adjacent, overlapping, or crossing each other during wiring. This not only increases the probability of energy transmission lines interfering with information transmission lines but also increases the risk of short circuits caused by contact between the energy and information transmission lines, ultimately affecting the operational reliability of the energy storage container.

[0063] To address the aforementioned technical problems, this application discloses an energy storage component. The energy transmission end and information transmission end of the battery pack are respectively positioned facing a first frame and a second frame, and are respectively connected to a first wiring harness and a second wiring harness on the first and second frames. The first and second frames are located on opposite sides of a support plate carrying the battery pack, allowing the first and second wiring harnesses to be arranged far apart on the frame, reducing the probability of mutual interference and thus improving the operational reliability of the energy storage component.

[0064] Please see Figures 1 to 3 , Figure 1 This is a side view of the energy storage component disclosed in the embodiments of this application. Figure 2 yes Figure 1 Another opposite side view of the energy storage module. Figure 3 yes Figure 1 A schematic diagram of the central energy storage rack.

[0065] The energy storage component 100 disclosed in this application embodiment is used in energy storage facilities such as energy storage containers, and can be used to realize the energy storage function of the energy storage facility. Figures 1 to 3 As shown, the energy storage assembly 100 includes an energy storage rack 110 and a battery pack 120. The energy storage rack 110 includes a multi-layer tray 111 and a frame 112 surrounding the tray 111. At least one battery pack 120 is mounted on the tray 111. The frame 112 has a first frame 1121 and a second frame 1122 located on opposite sides of the tray 111. The battery pack 120 has an energy transmission end 121 facing the first frame 1121 and an information transmission end 122 facing the second frame 1122. The energy transmission end 121 is connected to a first wiring harness 130 on the first frame 1121, and the information transmission end 122 is connected to a second wiring harness 140 on the second frame 1122.

[0066] The energy storage rack 110 can be used not only to place the battery pack 120, but also to arrange the wiring required to connect the battery pack 120. The energy storage rack 110 can include a multi-layer tray 111 and a frame 112. The multi-layer trays 111 can be stacked sequentially along the height direction Z of the energy storage rack 110, and adjacent trays 111 can be spaced apart. At least one battery pack 120 can be placed on the side of the tray 111 that faces the same direction as the height direction Z. The frame 112 is connected to the multi-layer trays 111 parallel to the periphery along the height direction Z, and can be arranged around the periphery of the multi-layer trays 111. The frame 112 not only supports the trays 111, but also arranges the wiring connecting the battery pack 120.

[0067] The frame 112 has a first frame 1121 and a second frame 1122 located on opposite sides of the tray 111. Both the first frame 1121 and the second frame 1122 can be used for wiring. The first frame 1121 can be provided with a first wire harness 130, and the second frame 1122 can be provided with a second wire harness 140. This allows the first wire harness 130 and the second wire harness 140 to maintain a large distance and be arranged far apart on the frame 112, which helps to reduce the probability of the first wire harness 130 and the second wire harness 140 interfering with each other.

[0068] The battery pack 120 can be placed on the side of the tray 111 that faces the same direction as the height Z, and energy transmission end 121 and information transmission end 122 can be respectively provided on opposite sides of the battery pack 120. The energy transmission end 121 can be positioned facing the first frame 1121 and can be connected to the first wiring harness 130 for energy transmission and storage. The information transmission end 122 can be positioned facing the second frame 1122 and can be connected to the second wiring harness 140 for data exchange by transmitting electrical signals.

[0069] Since the energy transmission end 121 is mainly used for transmitting electrical energy, and the information transmission end 122 is mainly used for transmitting electrical signals, the first wiring harness 130 connecting the energy transmission end 121 can be classified as a high-voltage wiring harness, while the second wiring harness 140 connecting the information transmission end 122 can be classified as a low-voltage wiring harness. Because the first wiring harness 130 and the second wiring harness 140 are positioned far apart on the frame 112, the electromagnetic radiation generated by the first wiring harness 130 has minimal interference with the electrical signals transmitted by the second wiring harness 140.

[0070] Meanwhile, the first wiring harness 130 and the second wiring harness 140, which are laid far apart, do not have adjacent, overlapping, or crossing wiring situations. This can isolate the short circuit risk that exists when the first wiring harness 130 and the second wiring harness 140 are laid close together, thereby reducing the probability of phenomena such as electric arcs and flames caused by contact failures of the first wiring harness 130 and the second wiring harness 140. Ultimately, this effectively improves the reliability, safety, and stability of the energy storage module 100.

[0071] In the above scheme, by setting the energy transmission end 121 and information transmission end 122 of the battery pack 120 to face the first frame 1121 and the second frame 1122 respectively, and connecting them to the first wiring harness 130 and the second wiring harness 140 on the first frame 1121 and the second frame 1122 respectively, and the first frame 1121 and the second frame 1122 being located on opposite sides of the support plate 111 carrying the battery pack 120, the first wiring harness 130 and the second wiring harness 140 can be laid on opposite sides of the battery pack 120 respectively, and both can have more and more space for wiring. In this way, not only is it helpful to improve the flexibility, convenience and safety of wiring the first wiring harness 130 and the second wiring harness 140, but it can also reduce the probability of mutual interference between the first wiring harness 130 and the second wiring harness 140, thereby improving the operational reliability of the energy storage component 100.

[0072] like Figures 1 to 2 As shown, in order to better perform wiring on the frame 112, the first frame 1121 has a first wire groove 113 for accommodating the first wire harness 130, and the second frame 1122 has a second wire groove 114 for accommodating the second wire harness 140.

[0073] To facilitate wiring on the first frame 1121, a first wire groove 113 can be recessed on the side of the first frame 1121 opposite to the second frame 1122. The first wire groove 113 can be used for wiring to form the aforementioned first wire harness 130. Similarly, a second wire groove 114 can be recessed on the side of the second frame 1122 opposite to the first frame 1121. The second wire groove 114 can also be used for wiring to form the aforementioned second wire harness 140.

[0074] In some embodiments, the location of the first wire groove 113 can be adjusted as needed, and is not limited to being formed on the side of the first frame 1121 opposite to the second frame 1122. For example, the first wire groove 113 can also be formed on other sides of the first frame 1121, as long as the first wire groove 113 can accommodate the first wire harness 130. Similarly, the location of the second wire groove 114 can also be adjusted as needed, and is not limited to being formed on the side of the second frame 1122 opposite to the first frame 1121. For example, the second wire groove 114 can also be formed on other sides of the second frame 1122, as long as the second wire groove 114 can accommodate the second wire harness 140.

[0075] In the above scheme, by setting the first wire trough 113 to accommodate the first wire harness 130 and the second wire trough 114 to accommodate the second wire harness 140, it helps to improve the wiring convenience and neatness of the first wire harness 130 and the second wire harness 140.

[0076] In some embodiments, in addition to arranging the first wire harness 130 and the second wire harness 140 through the first wire groove 113 and the second wire groove 114, the first wire harness 130 and the second wire harness 140 can also be fixed to the first frame 1121 and the second frame 1122 respectively by structures such as cable ties. That is, the design of the first wire groove 113 and the second wire groove 114 can also be omitted.

[0077] In some embodiments, at least one of the first wire trough 113 and the second wire trough 114 is provided with an electromagnetic shielding layer. And / or, the first wire trough 113 is further provided with a fireproof layer. The electromagnetic shielding layer may be made of a metallic material and may be disposed on the wall of at least one of the first wire trough 113 and the second wire trough 114. It can be used to shield electromagnetic radiation propagating from the first wire harness 130 toward the second wire harness 140, thereby further reducing electromagnetic interference from the first wire harness 130 to the second wire harness 140.

[0078] The fireproof layer can be made of fire-resistant material and can be installed on the wall of the first wire trough 113. It can be used to retard flames in the event of a high temperature caused by a fault in the first wiring harness 130, thereby reducing the risk of fire spreading from the energy storage component 100. It is understood that when both an electromagnetic shielding layer and a fireproof layer are provided within the first wire trough 113, the fireproof layer can cover the electromagnetic shielding layer. Alternatively, the electromagnetic shielding layer can cover the fireproof layer.

[0079] In the above solution, by providing an electromagnetic shielding layer on at least one of the first wire trough 113 and the second wire trough 114, the electromagnetic radiation generated by the first wire harness 130 can be blocked by the electromagnetic shielding layer, thereby reducing the interference of the electromagnetic radiation of the first wire harness 130 on the information transmission of the second wire harness 140. Simultaneously, by providing a fireproof layer within the first wire trough 113, the first wire harness 130 can be isolated by the fireproof layer in the event of a fire, thereby reducing the risk of fire spread.

[0080] like Figures 1 to 2 As shown, to improve the independence of the multiple battery packs 120, the energy transmission terminals 121 of the multiple battery packs 120 can be connected in parallel, and the information transmission terminals 122 of the multiple battery packs 120 can also be connected in parallel. Each battery pack 120's energy transmission terminal 121 has a corresponding wiring, and the wiring of the multiple battery packs 120's energy transmission terminals 121 can collectively form the aforementioned first wiring harness 130. Similarly, each battery pack 120's information transmission terminal 122 has a corresponding wiring, and the wiring of the multiple battery packs 120's information transmission terminals 122 can collectively form the aforementioned second wiring harness 140. Furthermore, the multiple battery packs 120 can also be modularly designed, meaning that the design standards of the multiple battery packs 120 can be consistent, facilitating parallel connection of the multiple battery packs 120 and connection to other external interfaces.

[0081] In the above scheme, by setting the energy transmission terminals 121 of multiple battery packs 120 to be connected in parallel and the information transmission terminals 122 of multiple battery packs 120 to be connected in parallel, multiple battery packs 120 can independently transmit power and interact with data. This not only improves the maintenance convenience of battery packs 120, but also facilitates the expansion of capacity by increasing the number of battery packs 120 in the future.

[0082] The battery pack 120 referred to in this embodiment may include multiple battery cells connected in parallel or series, and each battery cell may be a rechargeable battery. A rechargeable battery refers to a battery cell that can be recharged after discharge to activate its active materials and continue to be used. Furthermore, the battery cells may include, but are not limited to, lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, etc.

[0083] like Figure 1 As shown, in order to realize the energy transmission function of the battery pack 120, the energy transmission end 121 includes a positive electrode assembly 1211 and a negative electrode assembly 1212. Among them, the first wiring harness 130 includes a positive electrode trace 131 connected to the positive electrode assembly 1211 and a negative electrode trace 132 connected to the negative electrode assembly 1212.

[0084] The positive electrode assembly 1211 and the negative electrode assembly 1212 can be arranged alternately on the side of the battery pack 120 facing away from the information transmission terminal 122. The positive electrode assembly 1211 can be connected to the positive electrode line 131, and the negative electrode assembly 1212 can be connected to the negative electrode line 132, so that the battery pack 120 and the first wiring harness 130 can form a current loop to realize the charging and discharging function of the battery pack 120. When there are multiple battery packs 120, the first wiring harness 130 can also include multiple positive electrode lines 131 and negative electrode lines 132 matching the number of battery packs 120, to be connected to the positive electrode assemblies 1211 and negative electrode assemblies 1212 of multiple battery packs 120 respectively, thereby realizing the charging and discharging function of multiple battery packs 120.

[0085] The battery packs 120 placed on each tray 111 can be arranged opposite each other in the height direction Z, that is, the orthographic projections of the battery packs 120 on each tray 111 in the height direction Z can overlap. Furthermore, the lines connecting the positive electrode assemblies 1211 and the negative electrode assemblies 1212 of the battery packs 120 on each tray 111 can all be straight lines parallel to the height direction Z. This helps improve the neatness of the battery packs 120 placement on the multi-layer trays 111, so that the first wiring harness 130 can be connected to the positive electrode assembly 1211 and the negative electrode assembly 1212 respectively. It is understood that the positive electrode assembly 1211 referred to in this embodiment may include a positive terminal connected to the positive electrode line 131, and the negative electrode assembly 1212 may also include a negative terminal connected to the negative electrode line 132.

[0086] In some embodiments, the arrangement of the battery pack 120 on the tray 111 may not be limited to the scheme shown in the above embodiments. It is only necessary that the energy transmission end 121 of the battery pack 120 is arranged facing the first frame 1121 and the information transmission end 122 is arranged facing the second frame 1122. This embodiment will not be listed and described one by one.

[0087] In the above scheme, by setting the energy transmission end 121 of the battery pack 120 to have a positive electrode assembly 1211 and a negative electrode assembly 1212, and the first wiring harness 130 having a positive electrode line 131 connecting the positive electrode assembly 1211 and a negative electrode line 132 connecting the negative electrode assembly 1212, the battery pack 120 can be connected to an external high-voltage device through the first wiring harness 130 for charging and discharging, so as to realize the energy transmission between the battery pack 120 and the high-voltage device.

[0088] like Figure 1 As shown, to improve the wiring neatness of the first wire harness 130, the first wire trough 113 includes two first main wire troughs 1131 and multiple first branch wire troughs 1132. The two first main wire troughs 1131 are spaced apart, and the multiple first branch wire troughs 1132 are all connected to the two first main wire troughs 1131. The number of first branch wire troughs 1132 is the same as the number of layers of the tray 111, and they are arranged one-to-one with the multi-layer tray 111. The positive electrode wire 131 and the negative electrode wire 132 are respectively located in the two first main wire troughs 1131, and only one of the positive electrode wire 131 and the negative electrode wire 132 is located in the same first main wire trough 1131. One end of each of the positive electrode wire 131 and the negative electrode wire 132 is located in the first branch wire trough 1132 and is connected to the positive electrode assembly 1211 and the negative electrode assembly 1212, respectively.

[0089] To form the first wire groove 113 for laying the first wire harness 130, the first frame 1121 may include two first vertical beams 11211 and multiple first horizontal beams 11212. The two first vertical beams 11211 may be spaced apart, and their extension directions are parallel to the height direction Z. The opposite ends of the first horizontal beams 11212 are respectively connected to the two first vertical beams 11211, and the extension direction of the first horizontal beams 11212 is perpendicular to the height direction Z. Simultaneously, the first horizontal beams 11212 may be connected to the side of the pallet 111 parallel to the height direction Z, and multiple first horizontal beams 11212 may be arranged sequentially at intervals along the height direction Z. Furthermore, the number of first horizontal beams 11212 may be greater than or equal to the number of pallet layers 111, and each pallet layer 111 has one first horizontal beam 11212 on the side parallel to the height direction Z.

[0090] Two first main cable trays 1131 are respectively formed on two first vertical beams 11211, allowing the two first main cable trays 1131 to be arranged alternately. Multiple first branch cable trays 1132 can be respectively formed on multiple first horizontal beams 11212 corresponding to the multi-layer support plate 111, that is, each first horizontal beam 11212 corresponding to the support plate 111 is provided with a first branch cable tray 1132. One end of the positive electrode cable 131 connected to the positive electrode assembly 1211 can be introduced into the first branch cable tray 1132 and extend along the first branch cable tray 1132 towards a first main cable tray 1131, and then laid within that first main cable tray 1131. Similarly, one end of the negative electrode cable 132 connected to the negative electrode assembly 1212 is also directly introduced into the first branch cable tray 1132 and extends along the first branch cable tray 1132 towards another first main cable tray 1131, and then laid within that first main cable tray 1131. In addition, multiple positive wires 131 connecting multiple battery packs 120 can be laid in a first main wire groove 1131, while multiple negative wires 132 can be laid in another first main wire groove 1131.

[0091] In the above scheme, by setting the positive terminal line 131 and the negative terminal line 132 respectively in two spaced-apart first main cable trays 1131, and only one of the positive terminal line 131 and the negative terminal line 132 is in the same first main cable tray 1131, and one end of the positive terminal line 131 and the negative terminal line 132 are both located in the first branch cable tray 1132 and connected to the positive terminal assembly 1211 and the negative terminal assembly 1212 respectively, the positive and negative terminal lines can be wired at intervals after being connected to the positive and negative assemblies. This helps to improve the wiring convenience and regularity of the first wire harness 130.

[0092] In some embodiments, in addition to the wiring scheme shown in the above embodiments, the wiring methods of the positive terminal line 131 and the negative terminal line 132 can also be adjusted according to design requirements. For example, the positive terminal line 131 and the negative terminal line 132 can be simultaneously arranged in the same first main cable tray 1131. That is, there can be a variety of wiring methods for the first wire harness 130 in the first cable tray 113, which will not be listed and described in this embodiment.

[0093] like Figure 2 As shown, in order to realize the information transmission function of the battery pack 120, the information transmission end 122 includes at least one information transmission interface 1221, and the second wiring harness 140 includes an information transmission line 141 connected to the information transmission interface 1221.

[0094] The electrical signals required to be transmitted by the battery pack 120 can be transmitted through the information transmission interface 1221 and the information transmission line 141. The number of information transmission interfaces 1221 and information transmission lines 141 can be set according to the types of electrical signals required to be transmitted by the battery pack 120. For example, there can be three information transmission interfaces 1221, which can be used to transmit electrical signals from the battery monitoring module, the communication module, and the corresponding sensor module, respectively. Similarly, there can be three information transmission lines 141, which can be connected to the three information transmission interfaces 1221 respectively to receive and transmit electrical signals from the three information transmission interfaces 1221.

[0095] In the above scheme, by setting the information transmission end 122 of the battery pack 120 to have at least one information transmission interface 1221, and the second wiring harness 140 to have an information transmission line 141 connected to the information transmission interface 1221, the battery pack 120 can be connected to an external low-voltage device through the second wiring harness 140 to transmit information, so as to realize data interaction between the battery pack 120 and the low-voltage device.

[0096] like Figure 2 As shown, to improve the wiring neatness of the second wire harness 140, the second wire trough 114 includes a second main wire trough 1141 and multiple second branch wire troughs 1142. Each of the multiple second branch wire troughs 1142 is connected to the second main wire trough 1141. The number of second branch wire troughs 1142 is the same as the number of layers of the tray 111, and they are respectively arranged in a one-to-one correspondence with the multi-layer tray 111. The information transmission line 141 is located within the second main wire trough 1141, with one end located within a second branch wire trough 1142, and connected to the information transmission interface 1221.

[0097] To form the second wire trough 114 for laying the second wire harness 140, the second frame 1122 may include two second vertical beams 11221 and multiple second horizontal beams 11222. The two second vertical beams 11221 may be spaced apart, and their extension directions are parallel to the height direction Z. The two ends of the second horizontal beams 11222 are respectively connected to the two second vertical beams 11221, and their extension directions are perpendicular to the height direction Z. Simultaneously, the second horizontal beams 11222 may be connected to the opposite side of the support plate 111 parallel to the height direction Z, and multiple second horizontal beams 11222 may be arranged sequentially at intervals along the height direction Z. Furthermore, the number of second horizontal beams 11222 may be greater than or equal to the number of layers of support plates 111, and each layer of support plate 111 has one second horizontal beam 11222 on the opposite side parallel to the height direction Z. In this embodiment, the second frame 1122 and the first frame 1121 can be symmetrically arranged on opposite sides of the tray 111.

[0098] The first main cable tray 1131 can be formed on a second vertical beam 11221 near the information transmission interface 1221, while multiple second branch cable trays 1142 can be formed on multiple second horizontal beams 11222 corresponding to the multi-layer tray 111. That is, each second horizontal beam 11222 corresponding to the tray 111 is provided with a second branch cable tray 1142. One end of the information transmission line 141 connected to the information transmission interface 1221 can be introduced into the second branch cable tray 1142 and extend along the second branch cable tray 1142 towards the second main cable tray 1141, and then laid within the second main cable tray 1141. Furthermore, multiple information transmission lines 141 connecting multiple battery packs 120 can also be laid within the second main cable tray 1141 after extending along their respective second branch cable trays 1142.

[0099] In the above scheme, by setting the information transmission line 141 in the second main cable tray 1141 and one end in the second branch cable tray 1142 and connected to the information transmission interface 1221, the information transmission line 141 can be uniformly laid in the second main cable tray 1141 after being connected to the information transmission interface 1221. This helps to improve the wiring convenience and neatness of the second wire harness 140.

[0100] like Figures 2 to 3 As shown, in order to facilitate heat dissipation in conjunction with the cooling module of the battery pack 120, the second frame 1122 is also provided with a plurality of liquid cooling interfaces 150, the same number as the plurality of battery packs 120. Simultaneously, the battery pack 120 has a liquid cooling end 123 facing the second frame 1122 and connected to the liquid cooling interfaces 150, with each of the plurality of liquid cooling interfaces 150 corresponding to a liquid cooling end 123 of the plurality of battery packs 120.

[0101] The battery pack 120 includes a cooling module such as a cold plate for heat dissipation. A liquid cooling interface 150 connects to the cooling module via a liquid cooling end 123. The liquid cooling interface 150 not only supplies coolant or other cooling media to the cooling module but also receives coolant discharged from the cooling module, thus facilitating circulating heat dissipation. The number of liquid cooling interfaces 150 matches the number of battery packs 120, and the liquid cooling interfaces 150 can be positioned on a second crossbeam 11222 corresponding to the support plate 111 on which the battery packs 120 are placed, facilitating connection between the liquid cooling interface 150 and the liquid cooling end 123 of the battery pack 120.

[0102] To facilitate circulating heat dissipation with the cooling module, the liquid cooling interface 150 may include a liquid supply interface 151 and a liquid drain interface 152. The liquid cooling end 123 may also have an inlet end 1231 and an outlet end 1232 connected to the cooling module, and the liquid supply interface 151 and the liquid drain interface 152 can be connected to the inlet end 1231 and the outlet end 1232, respectively. The connection between the liquid supply interface 151 and the inlet end 1231, and the connection between the drain interface 152 and the outlet end 1232, can both be made via threads, which improves the ease of connection between the liquid cooling interface 150 and the liquid cooling end 123.

[0103] In the above solution, by setting a liquid cooling interface 150 on the second frame 1122 and connecting it to the liquid cooling end 123 of the battery pack 120, the battery pack 120 can be connected to an external heat dissipation device through the liquid cooling interface 150 to achieve heat exchange between the battery pack 120 and the heat dissipation device. At the same time, the liquid cooling interface 150 on the second frame 1122 can also be set away from the first wiring harness 130 to improve the isolation between the liquid cooling interface 150 and the first wiring harness 130.

[0104] In some embodiments, the liquid cooling interface 150 can be located not only on the second crossbeam 11222, but also on the second vertical beam 11221, or at other locations on the frame 112 other than the first frame 1121 and the second frame 1122. That is, the location of the liquid cooling interface 150 can be adjusted according to the design standards of the battery pack 120, and will not be listed in detail in this embodiment.

[0105] like Figures 2 to 3 As shown, in order to cooperate with the cooling module of the battery pack 120 for circulating heat dissipation, the second frame 1122 is provided with a liquid inlet pipe 160 connected to multiple liquid cooling interfaces 150, and has a pipe groove 115 for accommodating the liquid inlet pipe 160, and the liquid inlet pipe 160 and the second wire harness 140 are spaced apart.

[0106] The infusion pipe 160 can consist of multiple pipes, with each pair of pipes forming a group, connected to the supply port 151 and the drain port 152 respectively. Simultaneously, the two pipes in the same group can also be connected to external heat dissipation equipment, allowing the heat dissipation equipment to supply and recover coolant through two separate pipes. The infusion pipe 160 can be installed on the portion of the second frame 1122 where the second wiring harness 140 is not located, thus spacing the infusion pipe 160 from the second wiring harness 140.

[0107] To improve the ease and regularity of laying out the infusion tubing 160, a pipe channel 115 may be provided on the second frame 1122, and the pipe channel 115 may include a main channel 1151 and multiple branch channel channels 1152. The main channel 1151 may be formed on a second vertical beam 11221 without a second main channel 1141, while the multiple branch channel channels 1152 may be formed on multiple second horizontal beams 11222 with second branch channel channels 1142, and the branch channel channels 1152 and the second branch channel channels 1142 may be connected or independent. In this embodiment, the two pipes connecting the supply port 151 and the drain port 152 can be led out into the branch channel channels 1152 and can extend along the branch channel channels 1152 to be further laid out within the main channel channel 1151.

[0108] In some embodiments, the infusion tubing 160 may also consist of two main pipes and multiple branch pipes. The two main pipes may be an inlet pipe and an outlet pipe, and both the inlet and outlet pipes may be connected to multiple branch pipes. The two branch pipes connecting the inlet and outlet pipes may be a group, respectively connected to the supply port 151 and the drain port 152. In this embodiment, the two main pipes may be arranged within the main channel 1151, while the aforementioned group of branch pipes may be arranged within a branch channel 1152, connecting the supply port 151 and the drain port 152 corresponding to that branch channel 1152.

[0109] In the above solution, by connecting the infusion tube 160 to the liquid cooling interface 150 on the second frame 1122, the liquid cooling interface 150 can be connected to external heat dissipation equipment through the infusion tube 160. Simultaneously, by providing a pipe groove 115 in the second frame 1122 to accommodate the infusion tube 160, and by spacing the infusion tube 160 from the second wiring harness 140, the infusion tube 160 can also maintain isolation from the second wiring harness 140, thereby improving the isolation between the infusion tube 160 and the second wiring harness 140.

[0110] like Figures 2 to 3 As shown, in order to improve the independence of the multiple battery packs 120, the infusion tube 160 is also provided with multiple valves 170, the same number as the multiple liquid cooling interfaces 150. Among them, the multiple valves 170 are arranged one-to-one with the multiple liquid cooling interfaces 150, and the valves 170 are used to open or close the liquid cooling interfaces 150.

[0111] Valve 170 can be connected to the pipeline from infusion pipe 160 to supply coolant to supply port 151, and can be used to control the on / off state of this pipeline to open or close supply port 151, so that the coolant supply to each battery pack 120 can be independently controlled. When a battery pack 120 needs to be replaced or maintained, the operator can close supply port 151 through the corresponding valve 170 to stop the supply of coolant to the battery pack 120, and then remove the battery pack 120. This process will not affect the heat dissipation of other battery packs 120.

[0112] In the above scheme, by setting a valve 170 on the infusion tube 160, and the valve 170 can be used to open or close the liquid cooling interface 150, the liquid cooling heat dissipation of multiple battery packs 120 can be kept independent, so as to facilitate the maintenance or replacement of individual battery packs 120.

[0113] like Figure 3 As shown, in order to improve the safety of the energy storage component 100, a plurality of spray heads 180 are also provided on the frame 112. The plurality of spray heads 180 are located between the first frame 1121 and the second frame 1122, and at least one spray head 180 is provided above each layer of tray 111.

[0114] For mounting the sprinkler head 180, the frame 112 may further include multiple third crossbeams 1123 and multiple fourth crossbeams 1124. The third crossbeams 1123 are connected between a symmetrical set of first vertical beams 11211 and second vertical beams 11221, and the extension direction of the third crossbeams 1123 is perpendicular to the height direction Z. Simultaneously, the third crossbeams 1123 may also be connected to the side of the support plate 111 parallel to the height direction Z, and the multiple third crossbeams 1123 may be arranged sequentially at intervals along the height direction Z. Furthermore, the number of third crossbeams 1123 may be greater than or equal to the number of layers of support plates 111, and each layer of support plate 111 has one third crossbeam 1123 on the side parallel to the height direction Z.

[0115] The fourth crossbeam 1124 is connected between another set of symmetrical first vertical beams 11211 and second vertical beams 11221, and the extension direction of the fourth crossbeam 1124 is also perpendicular to the height direction Z. Simultaneously, the fourth crossbeam 1124 can also be connected to the opposite side of the pallet 111 parallel to the height direction Z, and multiple fourth crossbeams 1124 can be arranged sequentially at intervals in the height direction Z. Furthermore, the number of fourth crossbeams 1124 can be greater than or equal to the number of pallet layers 111, and each pallet layer 111 has one fourth crossbeam 1124 on the opposite side parallel to the height direction Z. In this embodiment, the number of first crossbeams 11212, second crossbeams 11222, third crossbeams 1123, and fourth crossbeams 1124 is the same, and the first crossbeams 11212 and second crossbeams 11222 are symmetrically arranged, as are the third crossbeams 1123 and fourth crossbeams 1124.

[0116] The sprinkler head 180 can be connected to external fire extinguishing equipment and can be used to spray gaseous or solid extinguishing media to extinguish fires in the battery pack 120. At least one sprinkler head 180 can be installed on each of the multiple third crossbeams 1123 and / or multiple fourth crossbeams 1124, and the sprinkler head 180 can also be located above the tray 111. For example, the battery pack 120 on the lower first tray 111 can be extinguished by the sprinkler head 180 on the corresponding third crossbeam 1123 and / or fourth crossbeam 1124 of the second tray 111, allowing the sprinkler head 180 to have a larger spray range and improve its fire extinguishing effect. Furthermore, the number of spray heads 180 provided on the third crossbeam 1123 and / or the fourth crossbeam 1124 can be adjusted according to the number of battery packs 120, such as one, two, three, four, five or more. It is only necessary to ensure that each battery pack 120 on each tray 111 has one or more corresponding spray heads 180. This embodiment will not list them one by one.

[0117] In the above scheme, by setting the sprinkler head 180 between the first frame 1121 and the second frame 1122, the sprinkler head 180 can avoid the first wiring harness 130 and the second wiring harness 140. At the same time, by setting the sprinkler head 180 above the support plate 111, the sprinkler head 180 can have a larger spray range, so that the sprinkler head 180 can extinguish the fire.

[0118] like Figure 3As shown, to improve the ease of expansion of the energy storage module 100, the tray 111 can be detachably connected to the frame 112, so that more trays 111 can be added to the frame 112 in the future, thereby expanding the capacity of the energy storage module 100. Meanwhile, the frame 112 can also be a modular structure, and the various components of the frame 112 can be detachably connected, allowing the structure of the frame 112 to be adjusted according to the number of trays 111. That is, the aforementioned first vertical beam 11211, first horizontal beam 11212, second vertical beam 11221, second horizontal beam 11222, third horizontal beam 1123, and fourth horizontal beam 1124 can be detachably connected by screws or other means.

[0119] In the above scheme, the energy storage module 100 can be expanded in capacity according to actual energy storage needs, both in the design and implementation stages. For example, if the capacity of the original design standard is insufficient, a support plate 111 can be added in the height direction Z, that is, the number of layers of the support plate 111 can be increased to support more battery packs 120. At the same time, the frame 112 can be lengthened by adding crossbeams and connecting new vertical beams to the existing vertical beams to connect and support the added support plates 111. In addition, when the energy storage module 100 is in the design stage, a larger support plate 111 can be designed to accommodate more battery packs 120 to expand the capacity based on the original design standard, and the structure of the frame 112 can be adjusted accordingly.

[0120] Please see Figures 4 to 5 , Figure 4 This is a front view of the energy storage component disclosed in the embodiments of this application. Figure 5 yes Figure 4 A top view of the energy storage components.

[0121] like Figures 4 to 5 As shown, when multiple battery packs 120 are placed on the tray 111, the multiple battery packs 120 can be arranged sequentially on the tray 111, and the arrangement direction of the multiple battery packs 120 on the tray 111 is perpendicular to the direction in which the first frame 1121 approaches or moves away from the second frame 1122. That is, the multiple battery packs 120 on the tray 111 can be arranged sequentially in the direction in which the third crossbeam 1123 approaches or moves away from the fourth crossbeam 1124, so that the energy transmission ends 121 of the multiple battery packs 120 on the tray 111 are facing the first frame 1121 without obstructing each other, and the information transmission ends 122 are facing the second frame 1122 without obstructing each other.

[0122] In the above scheme, by setting the arrangement direction of the multiple battery packs 120 on the tray 111 to be perpendicular to the direction of the first frame 1121 towards or away from the second frame 1122, the energy transmission ends 121 of the multiple battery packs 120 on the tray 111 can all be set towards the first frame 1121, and the information transmission ends 122 can all be set towards the second frame 1122, so that the multiple battery packs 120 on the tray 111 can be connected to the first wiring harness 130 and the second wiring harness 140 respectively.

[0123] In some embodiments, the arrangement of the multiple battery packs 120 on the tray 111 can also be adjusted according to design requirements. It is only necessary that the energy transmission end 121 and information transmission end 122 of the multiple battery packs 120 are respectively set towards the first frame 1121 and the second frame 1122. This embodiment will not be listed and described one by one here.

[0124] Please see Figures 6 to 8 , Figure 6 This is a schematic diagram of the energy storage device disclosed in the embodiments of this application. Figure 7 This is another structural schematic diagram of the energy storage device disclosed in the embodiments of this application.

[0125] like Figures 6 to 7 As shown in the embodiments of this application, the energy storage device 10 can be an energy storage container or other energy storage facility, and the energy storage device 10 includes: a housing assembly 200, a high-voltage device 300, a low-voltage device 400, and the aforementioned energy storage component 100. The housing assembly 200 has a receiving space 201, within which the high-voltage device 300, the low-voltage device 400, and the energy storage component 100 are all disposed. The high-voltage device 300 is connected to a first wiring harness 130, and the low-voltage device 400 is connected to a second wiring harness 140.

[0126] The housing assembly 200 can enclose and form the aforementioned accommodating space 201 for installing various functional components required for the energy storage device 10. A high-voltage device 300 is disposed within the accommodating space 201, and a first wiring harness 130 can connect the high-voltage device 300 and the energy transmission terminal 121, enabling power transmission between the high-voltage device 300 and the battery pack 120 to achieve charging and discharging of the battery pack 120. A low-voltage device 400 is disposed within the accommodating space 201, and a second wiring harness 140 can connect the low-voltage device 400 and the information transmission terminal 122, enabling information transmission between the low-voltage device 400 and the battery pack 120 to achieve data interaction between the battery pack 120 and the low-voltage device 400.

[0127] To enable power transmission and data exchange with the battery pack 120, the high-voltage device 300 may include high-voltage components such as a DC bus and a converter, while the low-voltage device 400 may include low-voltage components such as a battery control unit, a battery monitoring unit, and a battery communication unit. Of course, the high-voltage device 300 and the low-voltage device 400 can also be adjusted according to design requirements. It is sufficient that the high-voltage device 300 can be used for power transmission with the battery pack 120, and the low-voltage device 400 can be used for data exchange with the battery pack 120. This embodiment will not list them all here.

[0128] In the above scheme, by setting the first wiring harness 130 to connect the energy transmission end 121 and the high-voltage device 300, and the second wiring harness 140 to connect the information transmission end 122 and the low-voltage device 400, the battery pack 120 can transmit energy to the high-voltage device 300 through the first wiring harness 130, and transmit information to the low-voltage device 400 through the second wiring harness 140. Meanwhile, since the first wiring harness 130 and the second wiring harness 140 are respectively located on the first frame 1121 and the second frame 1122, and the first frame 1121 and the second frame 1122 are located on opposite sides of the support plate 111 that carries the battery pack 120, the first wiring harness 130 and the second wiring harness 140 can be arranged far apart on the frame 112. This helps reduce the probability of mutual interference between the first wiring harness 130 and the second wiring harness 140, thereby improving the operational reliability of the energy storage component 100.

[0129] like Figures 6 to 7 As shown, in order to install the functional components required for the energy storage device 10, the housing assembly 200 includes: a base 210, a roof 220, and a middle shell 230. The base 210 and the roof 220 are arranged opposite to each other, and the middle shell 230 connects the base 210 and the roof 220, and together with the base 210 and the roof 220, they enclose an accommodating space 201.

[0130] The base 210 and the roof 220 can be arranged opposite each other and spaced apart in the height direction Z, while the middle shell 230 can be located between the base 210 and the roof 220, and connected to the base 210 and the roof 220 respectively, so as to jointly enclose the accommodating space 201. The middle shell 230 can be detachably connected to the base 210 and the roof 220, which helps to improve the transportation convenience of the housing assembly 200. At the same time, when the energy storage assembly 100 needs to be expanded, that is, when a battery pack 120 is added, the base 210, the roof 220, and the middle shell 230 can also be disassembled to provide clearance space for the expansion of the energy storage assembly 100.

[0131] In the above scheme, by setting the middle shell 230 to connect the base 210 and the roof 220 respectively, and together with the base 210 and the roof 220 to form an accommodating space 201, the shell assembly 200 can accommodate the high-voltage equipment 300, the low-voltage equipment 400 and the energy storage component 100, so as to protect the high-voltage equipment 300, the low-voltage equipment 400 and the energy storage component 100, thereby improving the service life and reliability of the energy storage device 10.

[0132] In some embodiments, the base 210 may also be provided with drainage holes and a shock-absorbing device to ensure that the working environment of the energy storage component 100 is dry and stable.

[0133] like Figures 6 to 7 As shown, in order to facilitate the future expansion of the energy storage device 10, the middle shell 230 includes an outer frame 231 and a baffle 232. The outer frame 231 is detachably connected to the base 210 and the roof 220, and the baffle 232 is detachably mounted on the outer frame 231, and together with the base 210 and the roof 220, they enclose an accommodating space 201.

[0134] The outer frame 231 may include multiple support beams 2311 whose extension direction is parallel to the height direction Z. The lines connecting the multiple support beams 2311 can form a rectangle, and the opposite ends of the support beams 2311 can be detachably connected to the base 210 and the roof 220, respectively. Multiple baffles 232 can be detachably connected to the support beams 2311 and can cover the spaces between the multiple support beams 2311, thus forming the aforementioned accommodating space 201 together with the base 210 and the roof 220.

[0135] In some embodiments, in addition to the support beam 2311, the outer frame 231 may also include a reinforcing beam whose extension direction is perpendicular to the height direction Z, and the reinforcing beam may be connected to the support beam 2311 to improve the structural strength of the outer frame 231.

[0136] When the energy storage device 10 is in the landing stage and needs to be expanded, that is, when the energy storage module 100 needs to be expanded during the landing stage, since the energy storage module 100 needs to add a support plate 111 in the height direction Z and adjust the height of the frame 112, the support beam 2311 can also be adjusted simultaneously to replace it with a longer support beam 2311, or to connect a new support beam 2311 to the original support beam 2311 to increase the length, so as to expand the capacity of the energy storage module 100 without significantly changing the original design of the shell component 200.

[0137] To improve the adaptability of the housing assembly 200 in different environments, the structural design of the baffle 232 can be adjusted according to the actual scenario. For example, in hot and dry areas, the baffle 232 can be set as a mesh metal plate, utilizing the mesh aperture and density design to balance heat dissipation needs and animal intrusion prevention. In humid and rainy areas, the baffle 232 can be set as a metal plate or acrylic plate, and the moisture-proof performance can be enhanced by setting sealing strips between multiple baffles 232, and between the baffle 232 and the base 210 and the canopy 220. For example, in desert areas, the baffle 232 can also have a sand filter, and in coastal areas, the baffle 232 can also have an anti-corrosion coating.

[0138] In the above scheme, by setting an outer frame 231 to connect the base 210 and the roof 220, and detachably mounting a baffle 232 on the outer frame 231, which together with the base 210 and the roof 220 forms an accommodating space 201, the middle shell 230 can be assembled with a suitable baffle 232 and the outer frame 231 according to environmental requirements, thereby improving the applicability of the shell assembly 200 in different environments. At the same time, by setting the outer frame 231 to be detachably connected to the base 210 and the roof 220, the outer frame 231 can be decoupled from the base 210 and the roof 220, so as to facilitate the transportation and replacement of the outer frame 231, thereby meeting the future expansion needs of the energy storage assembly 100.

[0139] like Figures 6 to 7 As shown, in order to reduce the probability of water accumulation in the energy storage device 10, the canopy 220 has a flow guide surface 221 facing away from the accommodating space 201, and the flow guide surface 221 is a slope or arc surface, and is used to guide the fluid to flow in the direction close to the base 210.

[0140] The canopy 220 can adopt a roof-like structure, and the surface of the canopy 220 away from the accommodating space 201 can be provided with a drainage slope. For example, the canopy 220 can be arched in the direction away from the base 210, that is, in the height direction Z, so that the surface of the canopy 220 away from the accommodating space 201 can have a slope to form a guide surface 221 with an inclined or curved surface. In this way, the guide surface 221 can be used to quickly guide the fluid such as rainwater to flow down towards the base 210, which helps to improve the reliability of the energy storage device 10 in heavy rain environment.

[0141] The surface of the canopy 220 facing away from the accommodating space 201 may include two guide surfaces 221 and a transition surface 222 located between the two guide surfaces 221. The transition surface 222 is perpendicular to the height direction Z and is connected to both guide surfaces 221. Simultaneously, the transition surface 222 is higher than the two guide surfaces 221 in the height direction Z, and the two guide surfaces 221 can be symmetrically arranged about the transition surface 222, allowing the canopy 220 to arch in the height direction Z. In this embodiment, the slope or curvature of the guide surfaces 221 can be adjusted according to the actual layout of the energy storage device 10 to ensure that the energy storage device 10 has sufficient drainage capacity under extreme weather conditions.

[0142] In the above scheme, by setting the canopy 220 to have a guide surface 221 that is away from the accommodating space 201, and the guide surface 221 is a slope or arc surface, the guide surface 221 can guide the rainwater and other fluids on the canopy 220 to flow down toward the base 210, thereby reducing the probability of water accumulation on the canopy 220 in rainy weather.

[0143] like Figures 6 to 7 As shown, to reduce the impact of dust accumulation in the containment space 201 on the heat dissipation of the energy storage component 100, the energy storage device 10 further includes a fan assembly 500. The fan assembly 500 is mounted on the ceiling 220, and the ceiling 220 has an air duct 223 connecting the fan assembly 500 and the containment space 201. The fan assembly 500 is used to supply air into the containment space 201 to create a slightly positive pressure environment in the containment space 201.

[0144] A mounting platform 224 is formed on the transition surface 222 of the ceiling 220, and the fan assembly 500 is disposed within the mounting platform 224. An air inlet 2241 connecting the fan assembly 500 is formed on the side of the mounting platform 224. At the same time, the air duct 223 connects to the fan assembly 500 within the mounting platform 224, and an air outlet 2231 is formed on the side of the ceiling 220 located in the accommodating space 201. In addition, a baffle 225 is provided on the side of the mounting platform 224 facing away from the transition surface 222, and the baffle 225 protrudes from the periphery of the mounting platform 224 to reduce the probability of foreign objects entering the air inlet 2241.

[0145] When the fan assembly 500 is operating, it draws in air from the air inlet 2241 and then delivers the air into the accommodating space 201 through the air duct 223, creating a slightly positive pressure environment in the accommodating space 201 and reducing the probability of dust accumulation. A barometer can be installed in the accommodating space 201 to monitor the air pressure value and adjust the speed of the fan assembly 500 in real time based on the air pressure value, maintaining a slightly positive pressure environment in the accommodating space 201 to further reduce the probability of dust entering the accommodating space 201 and thus reduce dust accumulation.

[0146] In the above scheme, by installing a fan assembly 500 on the ceiling 220, and the ceiling 220 having an air duct 223 connecting the fan assembly 500 and the accommodating space 201, the fan assembly 500 can deliver air into the accommodating space 201 through the air duct 223 to form a slightly positive pressure environment in the accommodating space 201, which helps to reduce dust accumulation in the accommodating space 201.

[0147] like Figures 6 to 7 As shown, in order to further reduce dust accumulation on the battery pack 120, the air duct 223 has multiple air outlets 2231 that connect to the accommodating space 201. The multiple air outlets 2231 are arranged at intervals on the ceiling 220 and all face the frame 112.

[0148] The air duct 223 can be divided into a main duct connected to the ventilation fan assembly 500, and multiple branch ducts connecting the main duct and the accommodating space 201. Multiple branch ducts can form multiple air outlets 2231 on the surface of the ceiling 220 located within the accommodating space 201. These multiple air outlets 2231 can be spaced apart on the ceiling 220 and all can face the frame 112. For example, the ceiling 220 can be parallel to the guide surface 221, and multiple air outlets 2231 can be formed on the surface of the accommodating space 201, allowing the multiple air outlets 2231 to be tilted and facing the frame 112. In this way, the battery pack 120 can be located in the flow path of the airflow from the air outlets 2231. This not only assists in heat dissipation for the battery pack 120 but also allows the airflow to blow away accumulated dust from the battery pack 120.

[0149] In the above scheme, by setting the air duct 223 to have multiple air outlets 2231 that connect the accommodating space, and all the multiple air outlets 2231 are set towards the frame 112, the airflow from the multiple air outlets 2231 can flow towards the frame 112. This can not only help the battery pack 120 to dissipate heat, but also reduce the dust accumulation on the battery pack 120.

[0150] In some embodiments, the arrangement of multiple air outlets 2231 on the ceiling 220 can also be adjusted according to design requirements, as long as the accommodating space 201 can form a slightly positive pressure environment. This embodiment will not list them one by one.

[0151] Please see Figures 8 to 10 , Figure 8 This is a partial structural schematic diagram of the energy storage device disclosed in the embodiments of this application. Figure 9 This is another structural schematic diagram of the energy storage device disclosed in the embodiments of this application. Figure 10 This is another structural schematic diagram of the energy storage device disclosed in the embodiments of this application.

[0152] like Figures 8 to 10 As shown, to improve the connection convenience between the first wiring harness 130 and the high-voltage equipment 300, and between the second wiring harness 140 and the low-voltage equipment 400, the frame 112 has a first side 112a and a second side 112b arranged opposite to each other in the first direction X, and a third side 112c and a fourth side 112d arranged opposite to each other in the second direction Y, with the first direction X and the second direction Y being perpendicular to each other. The first side 112a is the side of the first frame 1121 facing away from the second frame 1122, and the second side 112b is the side of the second frame 1122 facing away from the first frame 1121. The high-voltage equipment 300 is located on the first side 112a, and the low-voltage equipment 400 is located on the second side 112b. Alternatively, the high-voltage equipment 300 is located on one of the third side 112c and the fourth side 112d, and the low-voltage equipment 400 is located on the other of the third side 112c and the fourth side 112d. Alternatively, both the high-voltage equipment 300 and the low-voltage equipment 400 are located on the third side 112c or the fourth side 112d.

[0153] Since the first wiring harness 130 is disposed on the first frame 1121 and the second wiring harness 140 is disposed on the second frame 1122, the high-voltage device 300 can be disposed on the first side 112a and the low-voltage device 400 can be disposed on the second side 112b, so that the high-voltage device 300 can be connected to the first wiring harness 130 and the low-voltage device 400 can be connected to the second wiring harness 140. At the same time, the high-voltage device 300 and the low-voltage device 400 can also be separated by the frame 112 to reduce the probability of mutual interference between them. In this embodiment, both the first direction X and the second direction Y are perpendicular to the height direction Z.

[0154] Depending on the design requirements of the energy storage device 10, the high-voltage equipment 300 can be located on the third side 112c, while the low-voltage equipment 400 can be located on the fourth side 112d. In this case, the first wiring harness 130 can be led out from the third side 112c and connected to the high-voltage equipment 300, while the second wiring harness 140 can be led out from the fourth side 112d and connected to the low-voltage equipment 400. Similarly, when the high-voltage equipment 300 is located on the fourth side 112d and the low-voltage equipment 400 is located on the third side 112c, the first wiring harness 130 can be led out from the fourth side 112d and connected to the high-voltage equipment 300, and the second wiring harness 140 can be led out from the third side 112c and connected to the low-voltage equipment 400. Of course, in addition to the above-mentioned layout scheme, the high-voltage equipment 300 and the low-voltage equipment 400 can be located on the same side, such as the third side 112c or the fourth side 112d, and the first wire harness 130 and the second wire harness 140 can be led out from the third side 112c or the fourth side 112d to be connected to the high-voltage equipment 300 and the low-voltage equipment 400 respectively.

[0155] In the above scheme, the high-voltage equipment 300 can be located on the first side 112a, while the low-voltage equipment 400 can be located on the second side 112b; or the high-voltage equipment 300 and the low-voltage equipment 400 can be located on the first side 112a and the second side 112b respectively; or both the high-voltage equipment 300 and the low-voltage equipment 400 can be located on the third side 112c or the fourth side 112d. This allows the high-voltage equipment 300 and the low-voltage equipment 400 to be flexibly arranged according to space requirements. Furthermore, when the high-voltage equipment 300 is located on the first side 112a and the low-voltage equipment 400 is located on the second side 112b, it helps improve the connection convenience between the high-voltage equipment 300 and the first wiring harness 130, as well as the connection convenience between the low-voltage equipment 400 and the second wiring harness 140.

[0156] Finally, in some specific application scenarios, to address the poor reliability of existing energy storage power stations, the energy storage component 100 disclosed in this application embodiment may include: a multi-layer tray 111 and a frame 112 surrounding the tray 111. At least one battery pack 120 is mounted on the tray 111. The frame 112 has a first frame 1121 and a second frame 1122 located on opposite sides of the tray 111. The battery pack 120 has an energy transmission end 121 facing the first frame 1121 and an information transmission end 122 facing the second frame 1122. The energy transmission end 121 is connected to a first wiring harness 130 on the first frame 1121, and the information transmission end 122 is connected to a second wiring harness 140 on the second frame 1122.

[0157] The first frame 1121 has a first wire groove 113 for accommodating the first wire harness 130, and the second frame 1122 has a second wire groove 114 for accommodating the second wire harness 140. At least one of the first wire groove 113 and the second wire groove 114 is provided with an electromagnetic shielding layer. And / or, the first wire groove 113 is also provided with a fire-resistant layer. The energy transmission terminals 121 of the multiple battery packs 120 can be connected in parallel, and the information transmission terminals 122 of the multiple battery packs 120 can also be connected in parallel.

[0158] The energy transmission terminal 121 includes a positive electrode assembly 1211 and a negative electrode assembly 1212. The first wiring harness 130 includes a positive electrode trace 131 connected to the positive electrode assembly 1211 and a negative electrode trace 132 connected to the negative electrode assembly 1212. The information transmission terminal 122 includes at least one information transmission interface 1221, and the second wiring harness 140 includes an information transmission line 141 connected to the information transmission interface 1221.

[0159] The second frame 1122 is also provided with a plurality of liquid cooling interfaces 150, the same number as the plurality of battery packs 120. Meanwhile, each battery pack 120 has a liquid cooling end 123 facing the second frame 1122 and connected to the liquid cooling interface 150, with each of the plurality of liquid cooling interfaces 150 corresponding to a liquid cooling end 123 of each of the plurality of battery packs 120. The second frame 1122 is provided with infusion tubes 160 connected to the plurality of liquid cooling interfaces 150, and has a pipe groove 115 for accommodating the infusion tubes 160, with the infusion tubes 160 and the second wiring harness 140 spaced apart.

[0160] The infusion tube 160 is also equipped with a plurality of valves 170, the same number as the plurality of liquid cooling interfaces 150. Each valve 170 corresponds one-to-one with a liquid cooling interface 150, and the valves 170 are used to open or close the liquid cooling interfaces 150. The frame 112 is also equipped with a plurality of spray heads 180. These spray heads 180 are located between the first frame 1121 and the second frame 1122, and at least one spray head 180 is correspondingly located above each layer of support plate 111.

[0161] The energy storage component 100 disclosed in this application embodiment has its energy transmission end 121 and information transmission end 122 of the battery pack 120 respectively facing the first frame 1121 and the second frame 1122, and respectively connected to the first wiring harness 130 and the second wiring harness 140 on the first frame 1121 and the second frame 1122. The first frame 1121 and the second frame 1122 are located on opposite sides of the support plate 111 that carries the battery pack 120, so that the first wiring harness 130 and the second wiring harness 140 can also be arranged on opposite sides of the battery pack 120, and both can have more and more space for wiring. In this way, not only can the flexibility, convenience and safety of the first wiring harness 130 and the second wiring harness 140 be improved, but the probability of the first wiring harness 130 and the second wiring harness 140 interfering with each other can also be reduced, thereby improving the operational reliability of the energy storage component 100.

[0162] The above are merely embodiments of this application and do not limit the scope of this patent application.
