Description

Technical Field

[0001] This utility model belongs to the field of batteries, specifically relating to an energy storage container and energy storage equipment. Background Technology

[0002] In the field of energy storage containers, the safety protection of battery packs is a core design consideration, and the reliability of the fire protection system directly affects the effectiveness of preventing thermal runaway of the battery packs. In existing technologies, the fire sprinkler systems of energy storage containers generally adopt a top-centralized sprinkler design, where the outlets of the fire-fighting pipelines are mainly concentrated at the top of the container, and the battery packs inside the container are extinguished and cooled by a top-down water flow.

[0003] However, this top-spraying method has significant limitations: when multiple battery packs are arranged along the height of the enclosure, the battery packs located in the lower middle section are easily blocked by the upper battery packs or supporting structures, creating a blind spot for the spray. Once these lower middle battery packs experience thermal runaway, the spray water cannot effectively reach them, failing to extinguish and cool the fire source in time, which can easily lead to the spread of the fire. Summary of the Invention

[0004] The purpose of this utility model is to provide an energy storage container and energy storage equipment, overcoming the defects of the existing energy storage container fire protection system, which uses a top sprinkler method, resulting in insufficient spray coverage of the middle and lower battery packs arranged along the height direction and the easy formation of spray blind spots.

[0005] The first aspect of this utility model provides an energy storage container, including a container body, a support frame located inside the container body, and a fire sprinkler system;

[0006] The aforementioned support frame is provided with at least m battery pack mounting positions arranged along the height direction of the enclosure; where m is an integer greater than 2; the battery pack mounting position near the top of the enclosure is defined as the first battery pack mounting position, and the battery pack mounting position near the bottom of the enclosure is defined as the mth battery pack mounting position.

[0007] The aforementioned fire sprinkler system includes a fire hose assembly, which includes an inlet end and multiple outlet ends; the inlet end is used to connect to the fire-fighting medium device interface, and at least one outlet end corresponds to the i-th battery pack installation position, where i is greater than 1 and less than or equal to m.

[0008] At least one outlet end of the fire-fighting pipe assembly of this utility model is specifically designed for the i-th battery pack installation position (i is greater than 1 and less than or equal to m), which can directly deliver the fire-fighting medium to the middle and lower battery packs arranged along the height of the container. This design effectively breaks the limitation of the traditional top sprinkler system, where the middle and lower battery packs are easily blocked, forming a sprinkler blind zone. It ensures that when thermal runaway occurs in these battery packs, the fire-fighting medium can act on the fire source in a timely and accurate manner, greatly reducing the risk of fire spread and significantly improving the fire safety of the energy storage container.

[0009] Furthermore, the location of at least one outlet end of the aforementioned fire-fighting pipe assembly corresponds to the first battery pack mounting position.

[0010] A new outlet end corresponding to the first battery pack installation position is added, which works in conjunction with the original middle and lower outlet end to achieve precise full-height coverage of the battery pack, eliminate fire blind spots, and ensure rapid fire control in the event of thermal runaway.

[0011] Furthermore, the aforementioned fire protection pipe assembly includes a main fire protection pipe and multiple fire protection branch pipes connected to the main fire protection pipe;

[0012] The inlet end of the aforementioned main fire pipe is used to connect to the interface of the fire-fighting medium device; the aforementioned multiple outlet ends are set on each of the aforementioned branch fire pipes.

[0013] The main fire pipe serves as the primary channel to ensure a stable supply of fire-fighting media. Multiple fire branch pipes can be independently designed in terms of route and length according to the distribution of different battery pack installation locations, which can accurately adapt to battery packs of different heights and positions.

[0014] Furthermore, a portion of the aforementioned support frame is a hollow structure, serving as the fire-fighting branch pipe. Integrating the fire-fighting branch pipe with the support frame eliminates the need for separate fire-fighting branch pipes outside the support frame, avoiding spatial conflicts between pipelines and the support frame. This is particularly suitable for energy storage containers with densely packed battery packs, achieving a dual integration of support and fire-fighting functions within a limited space, thus improving overall space utilization. In addition, it saves on the material costs and installation procedures for separately fabricating fire-fighting branch pipes, reduces the number of parts, simplifies the assembly process, and shortens the construction cycle.

[0015] Furthermore, the aforementioned support frame includes n brackets spaced apart along the length of the box; where n is an integer greater than 1.

[0016] A battery cluster mounting position is formed between adjacent brackets; each battery cluster mounting position includes m battery pack mounting positions arranged along the height direction of the enclosure.

[0017] Furthermore, the aforementioned support structure includes multiple first support beams and multiple second support beams;

[0018] Each first support beam extends along the height direction of the box body, and multiple first support beams are arranged along the width direction of the box body;

[0019] Each second support beam extends along the width of the box body, and multiple second support beams are arranged along the height of the box body and fixed to the first support beam;

[0020] The battery pack mounting position is formed between two second support beams located on the same horizontal plane;

[0021] The first support beam of each bracket is a hollow structure, serving as a fire-fighting branch pipe.

[0022] Compared to using the second support beam as a fire branch pipe, the first support beam extends along the height of the enclosure and can traverse multiple battery pack installation positions arranged along the height of the enclosure (i.e., multiple battery packs in the same vertical plane). Multiple outlet ends can be set on a single first support beam to cover installation positions at different heights. In contrast, the second support beam extends along the width of the enclosure and only corresponds to a single or part of the battery pack installation positions at the same height. Multiple second support beams are required to cover multiple layers, making the integrated coverage capability of the first support beam superior.

[0023] Furthermore, each bracket has at least one first support beam with j outlet ends, and adjacent two battery packs in each battery cluster share one outlet end, where j is an integer greater than 1.

[0024] While ensuring basic fire protection coverage, this approach reduces the number of outlets compared to setting up a separate outlet for each battery pack on each floor, thus lowering pipe processing and installation costs. It also reduces structural weaknesses caused by too many outlets, improving the structural stability of the first support beam as a load-bearing component. For scenarios with low risk of thermal runaway or where adjacent battery packs are close together, the spray angle and coverage of the outlets can be rationally designed to ensure fire extinguishing effectiveness while controlling costs.

[0025] The second aspect of this utility model provides an energy storage device, including the above-mentioned energy storage container and multiple battery packs; the battery packs are installed one-to-one in the battery pack mounting positions.

[0026] Furthermore, the aforementioned energy storage device also includes an explosion venting manifold and a flue gas treatment device. The inlet end of the explosion venting manifold is connected to the explosion vent of each battery in the battery pack, and the outlet end of the explosion venting manifold is connected to the flue gas treatment device, which is used to treat the flue gas from battery thermal runaway. The design of the explosion venting manifold ensures that the explosion fumes from each battery are discharged through a unified path, avoiding the problem of excessively high local concentrations caused by disorderly diffusion of fumes within the enclosure, and reducing the risk of secondary disasters caused by fumes igniting other batteries or components.

[0027] Furthermore, the aforementioned flue gas treatment equipment includes at least one of a liquid treatment device, a solid treatment device, a flue gas cooling device, and an ignition device;

[0028] The liquid handling unit is mainly used to treat the electrolyte and gas in thermal runaway flue gas;

[0029] Flue gas cooling devices are mainly used for cooling thermal runaway flue gas;

[0030] The solids processing unit is mainly used for adsorption treatment of gases in thermal runaway flue gas;

[0031] The ignition device is used to ignite the thermal runaway flue gas.

[0032] The flue gas treatment device of this utility model treats the thermal runaway flue gas generated by the energy storage device in a variety of ways to avoid the safety hazards caused by the discharge of thermal runaway flue gas.

[0033] The beneficial effects of this utility model are:

[0034] At least one outlet end of the fire-fighting pipe assembly of this utility model is specifically designed for the i-th battery pack installation position (i is greater than 1 and less than or equal to m), which can directly deliver the fire-fighting medium to the middle and lower battery packs arranged along the height of the container. This effectively overcomes the problem of the middle and lower battery packs being easily blocked and forming a spray blind zone in the traditional top sprinkler system, ensuring that when thermal runaway occurs in these battery packs, the fire-fighting medium can act on the fire source in a timely and accurate manner, greatly reducing the risk of fire spread and significantly improving the fire safety of the energy storage container.

[0042] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] In the description of this utility model, it should be noted that the terms "top," "bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] This utility model discloses an energy storage container that, compared to existing energy storage containers, can deliver fire-fighting media to the battery packs in the lower middle section, overcoming the limitation of traditional top-sprinkler systems where the lower middle battery packs are easily obstructed, creating blind spots in the sprinkler system. When thermal runaway occurs in the battery packs in this area, it ensures that the fire-fighting media acts on the fire source promptly and accurately, significantly reducing the risk of fire spread and substantially improving the fire safety of the energy storage container.

[0046] Specifically, the energy storage container of this utility model mainly consists of a container body, a supporting frame located inside the container body, and a fire sprinkler system.

[0047] A rectangular box is typically used. For ease of description, the length direction of the box can be defined as the x-direction, the height direction as the z-direction, and the width direction as the y-direction.

[0048] The support frame is constructed from multiple sets of brackets to form multiple battery pack mounting positions. For ease of description, the battery pack mounting position near the top of the box (i.e., the topmost battery pack mounting position) is defined as the first battery pack mounting position, and the battery pack mounting position near the bottom of the box (i.e., the bottommost battery pack mounting position) is defined as the mth battery pack mounting position, where m is an integer greater than 2.

[0049] The fire sprinkler system includes a fire hose assembly, the inlet of which is connected to the fire-fighting medium interface device; the fire hose assembly is equipped with multiple outlets, at least one of which corresponds to the i-th battery pack mounting position (i is greater than 1 and less than or equal to m). That is, at least one outlet corresponds to the battery pack mounting position located in the lower middle part or the lower middle layer.

[0050] It should be noted that the term "correspondence" here can be understood as:

[0051] In terms of spatial location, the outlet end is positioned relative to the i-th battery pack installation position (lower middle part), meaning that the spray direction or coverage of the outlet end directly points to the area where the installation position is located, ensuring that the fire-fighting medium sprayed from the outlet end can directly act on the battery pack installed at that installation position.

[0052] This invention provides precise fire protection for battery packs at different heights within an energy storage container, with a particular emphasis on protecting the lower and middle battery packs, effectively solving the coverage blind spot problem of traditional top sprinkler systems.

[0053] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0054] Example 1

[0055] like Figure 1 As shown, the energy storage container in this embodiment adopts a rectangular box body, which is formed by a box body 1 with at least one open end and a first door panel (not shown in the figure), wherein the first door panel is used to open or close the open end of the box body 1.

[0056] A second door panel 14 is also provided inside the housing 1. The second door panel 14 divides the inner cavity of the housing 1 into two independent and isolated compartments in the x direction, which are defined as battery compartment 11 and equipment compartment 12, respectively.

[0057] Battery compartment 11, as the core functional area of ​​the entire energy storage container, is primarily used to house the battery pack 7. Equipment compartment 12 is typically used to house temperature control equipment and fire safety systems. The temperature control system can monitor temperature changes within battery compartment 11 in real time. Once the temperature exceeds the preset suitable range, the temperature control system will quickly activate the cooling or heating devices to ensure that the battery pack 7 always operates in an optimal temperature environment, effectively extending the service life of the battery pack 7 and improving the overall performance of the energy storage equipment. If the fire safety system detects a fire hazard within battery compartment 11, it can respond and initiate fire suppression procedures.

[0058] When space is limited in equipment compartment 12, some fire safety systems can be integrated into battery compartment 11. For example... Figure 1 As shown, in this embodiment, an independent subspace 13 is divided within the battery compartment 11 for arranging part of the fire safety system. The setting of this subspace 13 does not affect the normal installation and operation of the battery pack 7, which ensures both the flexibility of the equipment layout and the core function of the battery compartment 11 is not interfered with.

[0059] In this embodiment, the support frame 2 is installed inside the battery compartment 11, from... Figure 1 It can be seen that it is mainly composed of six parallel supports 21. Figure 1 (The leftmost bracket 21 is not shown in the figure). As can be seen from the figure, in this embodiment, six parallel brackets 21 are arranged at intervals along the x-direction, dividing the battery compartment 11 into five battery cluster mounting positions 23.

[0060] In other embodiments, the number and arrangement of the brackets 21 can be flexibly adjusted according to actual needs. The required number and arrangement of battery cluster mounting positions 23 can be formed by increasing or decreasing the number of brackets 21 or adjusting the arrangement of the brackets 21 (the number of battery cluster mounting positions 23 is one less than the number of brackets 21).

[0061] like Figure 2 and Figure 3 The diagram shown is a partially enlarged structural schematic of the bracket 21 in this embodiment. As can be seen from the diagram, the bracket 21 in this embodiment includes multiple first support beams 211 and second support beams 212; each first support beam 211 extends along the z-direction, and the multiple first support beams 211 are arranged at equal intervals along the y-direction; each second support beam 212 extends along the y-direction, and the multiple second support beams 212 are arranged at equal intervals along the z-direction and fixed to the first support beams 211. (Combined with...) Figure 1 Within each battery cluster mounting position, two brackets 21 are located between two second support beams 212 on the same xy plane to form a battery pack mounting position. Figure 1As can be seen from the diagram, in this embodiment, the four battery cluster mounting positions 23 near the left side each include 10 battery pack mounting positions arranged along the y direction, and the battery cluster mounting position 23 near the right side (i.e. near the equipment compartment 12) includes 7 battery pack mounting positions arranged along the y direction. The space above the battery cluster mounting position 23 is a subspace 13, which serves as part of the fire protection system installation space.

[0062] In other embodiments, the structure of the bracket 21 and the arrangement and number of battery pack mounting positions can be flexibly adjusted according to the size and energy storage capacity of the battery pack 7.

[0063] from Figure 2 and Figure 3 As can be seen from the diagram, in this embodiment, the first support beam 211 is made of square steel and has a hollow structure, while the second support beam 212 is made of angle steel. The vertical plate of the angle steel is fixed to the first support beam 211, and the horizontal plate is used to support the battery pack 7. The vertical plate of the angle steel can be fixed to the square steel by welding. In addition, to improve the bonding strength between the two, in this embodiment, a support stiffener can also be fixed between the horizontal plate of the angle steel and the first support beam 211.

[0064] In some other embodiments, the first support beam 211 may be a hollow profile such as a rectangular tube or a round tube, and the second support beam 212 may be a channel steel, flat steel or H-beam.

[0065] Combination Figure 1 and Figure 4 In this embodiment, the fire sprinkler system includes a fire pipe assembly, which includes a main fire pipe 3 and multiple fire branch pipes 33 connected to the main fire pipe 3.

[0066] The inlet end 31 of the main fire pipe is used to connect to the fire-fighting medium device interface; wherein the fire-fighting medium device interface usually refers to the interface for connecting to an external fire-fighting medium supply device; the fire-fighting medium is usually water, and the corresponding fire-fighting medium device can be a water supply device such as a fire water system; this utility model does not exclude the use of other fire-fighting media (such as gas extinguishing media, etc.), in which case the fire-fighting medium device can be a special storage tank or supply equipment for storing such media.

[0067] As shown in the figure, in this embodiment, the main fire pipe 3 is located on the bottom plate of the enclosure 1, extends along the x-direction, and passes through each battery cluster mounting position 23. In some other embodiments, the main fire pipe 3 can be placed at the top or middle of the enclosure 1 depending on the specific spatial layout. However, compared to this embodiment, when the main pipe is located at the top or middle, it is more likely to cause interference with other structures (such as the support frame 2, battery cluster wiring device, etc.). In this embodiment, placing the main pipe on the bottom plate of the enclosure 1 can reduce such interference and reduce the complexity of the pipeline routing design.

[0068] In this embodiment, the first supporting beam 211 of the hollow structure is used as the fire-fighting branch pipe 33, from... Figure 1 and Figure 4 As can be seen, each bracket 21 has at least one first support beam 211 serving as a fire branch pipe 33, which is connected to the main fire pipe 3 via a connecting pipe 32. Simultaneously, the first support beam 211 is equipped with multiple outlet ends 22 (such as...). Figure 2 As shown in the figure, each outlet end 22 corresponds to the battery pack installation position in the battery cluster installation position 23, realizing the integrated design of support function and fire protection function, effectively saving space and simplifying pipeline layout.

[0069] The number of outlets 22 can be flexibly configured according to actual spraying needs or the risk level of thermal runaway of battery pack 7: if it is necessary to enhance the precise protection of each layer of battery pack 7, outlets 22 can be set on the first support beam 211 layer by layer to ensure that each layer of battery pack 7 corresponds to one outlet 22; if it is necessary to balance structural strength and system simplification, the number of outlets 22 can be reduced, and a design of sharing one outlet 22 for every two or three layers of battery pack 7 can be adopted. This not only reduces the cost of pipeline processing, but also reduces the structural weakening of the first support beam 211 due to too many openings, and improves its stability as a load-bearing component. At the same time, the fire-fighting effect is ensured by optimizing the spray angle and coverage.

[0070] Combination Figures 1 to 4 In this embodiment, five outlet ends 22 are opened on the first support beam 211 corresponding to the four battery cluster mounting positions 23 far away from the equipment compartment, and three outlet ends 22 are opened on the first support beam 211 corresponding to one battery cluster mounting position 23 close to the equipment compartment. A spray head 4 is installed on each outlet end 22. Figure 3 As shown), every two battery packs 7 within each battery cluster share a single outlet end 22.

[0071] In some other embodiments, depending on the actual sprinkler requirements or space constraints, the first support beam 211 in part of the bracket 21 can be used as a fire branch pipe 33 to meet the basic fire protection coverage requirements.

[0072] In addition, in some other embodiments, fire branch pipes 33 can be installed separately. However, compared with this embodiment, installing them separately will increase the space occupied by the pipes and require additional fixing structures, which may cause spatial conflicts with the support frame 2, and also increase material and installation costs. The integrated first support beam 211 design in this embodiment has advantages in terms of space utilization, structural stability and economy.

[0073] Example 2

[0074] This embodiment is an energy storage device, such as... Figure 5As shown, it includes the energy storage container described in Embodiment 1 and multiple battery packs 7, with each battery pack 7 installed in a corresponding battery pack mounting position.

[0075] The energy storage device in this embodiment also includes an explosion venting manifold 5 and a flue gas treatment device 6; the inlet end of the explosion venting manifold 5 is connected to the explosion venting section of each battery pack 7, and the outlet end 22 is connected to the flue gas treatment device 6; the flue gas generated by the thermal runaway of the battery pack 7 is concentratedly discharged through the explosion venting manifold 5 and transported to the flue gas treatment device 6 for treatment.

[0076] It should be noted that the explosion vent of the battery pack 7 can specifically refer to the explosion vent structure of each battery module or large-capacity battery within the battery pack 7, which is usually a pressure relief port or explosion vent provided on the casing of the battery module or large-capacity battery.

[0077] from Figure 5 As can be seen from the figure, in this embodiment, some components of the flue gas treatment device 6 are fixed in an independent subspace 13 divided within the battery compartment 11.

[0078] The flue gas treatment equipment 6 may include at least one of a liquid treatment device, a flue gas cooling device, a solid treatment device, and an ignition device 61 (the ignition device 61 is located outside the housing 1). When multiple devices are used, the combination of the devices is not limited to series connection, and any combination can be adopted according to the actual flue gas treatment requirements. For example, only the liquid treatment device and the ignition device 61 may be set up. The liquid treatment device first treats the electrolyte and gas in the thermal runaway flue gas, and then the ignition device 61 ignites the thermal runaway flue gas. Alternatively, a combination of a flue gas cooling device and a solid treatment device may be used to cool down the flue gas first and then adsorb impurities.

[0079] In this embodiment, the flue gas treatment equipment 6 can be defined as a primary fire protection unit, and the fire sprinkler system can be defined as a secondary fire protection unit. It should be noted that this embodiment does not exclude the possibility of adding other fire protection units.

[0080] When thermal runaway occurs in battery pack 7, the thermal runaway fumes from the battery can be led out to the primary fire unit for treatment through the explosion relief manifold 5 to prevent heat spread and avoid the thermal runaway of individual battery pack 7 causing other battery pack 7 or even the entire energy storage device to explode due to heat spread. At the same time, it can prevent the accumulation of high-temperature and high-pressure gas in a confined space and the resulting danger.

[0081] When thermal runaway smoke is present in the energy storage device's enclosure 1, the battery pack 7 temperature exceeds the set threshold, or combustion or explosion occurs, the secondary fire-fighting unit is activated to spray fire extinguishing materials onto the thermal runaway smoke and the burning or exploding battery in the enclosure 1, thereby enhancing fire extinguishing capabilities and further preventing the continued occurrence of thermal runaway.

[0082] It should be noted that when the secondary fire protection unit is activated, the ignition device 61 in the primary fire protection unit will not work.
