The traditional new energy fire-fighting technology means is to spray fire extinguishing agent for fire extinguishing through the alarm detection system and the related electric control equipment linkage fire extinguishing system after the battery cell thermal runaway, but it does not have the cooling capacity for the thermal runaway object.

[0043] Specifically, in an optional embodiment provided by the present disclosure, the energy storage battery security system OO includes a containing space D, which is not particularly a container of a certain type, but generally includes a closed shell of an energy storage module E, a fully open or partially open shell, an area of an electric core, electrolyte, module, production or process (stirring, coating, cold pressing and pre-cutting, tab die cutting and striping, winding, baking and liquid injection, electric core activation, formation and separation, etc.) of the energy storage module E, a workshop, a loading and unloading platform, a test needle bed, a warehouse, a storage location, a shelf, a shed, a test line, etc. The energy storage module E includes a battery, which can be a battery production area or a battery use area.

[0049] Please refer to Figures 7 to 10For a large-scale energy storage station including tens, hundreds or thousands of accommodation spaces D, the field area of the energy storage station is large, and the storage module A includes a storage tank A1, which can be arranged at multiple points. For example, a 20-ton storage tank A1 is divided into two 10-ton storage tanks A1 for two-point arrangement, or four 5-ton storage tanks A1 for four-point arrangement, or two 5-ton storage tanks A1 and one 10-ton storage tank A1 for three-point arrangement. Specific examples are not listed one by one, and the volume and arrangement of the storage tank A1 can be designed according to the actual site arrangement of the accommodation space D to meet the fire-fighting requirements.

[0050] Please continue to refer to Figures 1 to 10 In an optional embodiment provided in the present disclosure, the energy storage battery security system OO includes a fire extinguishing, cooling and inerting module C. When the battery management module F monitors that the dangerous parameter value in the accommodation space D is between the preset first threshold R1 and the second threshold R2, the battery management module F controls the control valve H of the fire extinguishing, cooling and inerting module C, the storage module A and the conveying module B to open, the fire extinguishing agent in the storage module A flows to the fire extinguishing, cooling and inerting module C inside the accommodation space D through the conveying module B, and the thermal runaway object inside the energy storage module E in the accommodation space D is accurately cooled and cooled. The fire extinguishing agent can be circulated to the storage module A through the recovery part and the recovery pipeline to realize the integrated circulation of fire extinguishing agent cooling and recovery. The conveying module B can also be a non-circulating pipeline, that is, the fire extinguishing agent conveyed to the accommodation space D is not circulated to the storage module A through the recovery part and the recovery pipeline, but is discharged to the atmosphere through the exhaust and pressure relief module G. The dangerous parameter value is the index monitoring value mentioned above.

[0051] It should be noted that in some embodiments, the energy storage battery security system OO can also include a mobile assembly. The mobile assembly is movably arranged in the accommodation space D. The fire extinguishing, cooling and inerting module C is connected with the mobile assembly. Thus, the fire extinguishing, cooling and inerting module C can move with the mobile assembly, so as to be moved to a specified location according to the needs of the fire-fighting system, which is beneficial to improve the accuracy of fire extinguishing.

[0052] For example, the mobile assembly can include a guide rail, a moving part and a driving motor. The moving part is slidably connected with the guide rail. The driving motor drives the moving part to slide on the guide rail, and the fire extinguishing, cooling and inerting module C can be connected with the moving part. Thus, the moving part can drive the fire extinguishing, cooling and inerting module C to move when the moving part moves.

[0053] When the battery management module F monitors that the dangerous parameter value in the containing space D exceeds the second threshold R2, the battery management module F controls the control valve H of the storage module A and the conveying module B to open, the fire extinguishing agent in the storage module A is conveyed to the fire extinguishing cooling and inerting module C through the conveying pipeline B, and then is discharged into the containing space D by the fire extinguishing cooling and inerting module C. The heat-absorbing and gasified fire extinguishing agent dilutes and inertizes the combustible gas in the containing space D, thereby playing a role in suppressing the explosion of the combustible gas.

[0054] Please continue to refer to Figures 1 to 10 In an optional embodiment provided by the present disclosure, the energy storage battery security system OO includes an exhaust pressure relief module G located above the side wall of a face of each containing space D. The exhaust pressure relief module G includes at least one exhaust pressure relief device that is mechanically opened or closed when the ambient pressure reaches a pressure threshold, thereby playing a role in reducing the pressure in the containing space D and inerting the combustible gas concentration in the energy storage module E at the moment of fire extinguishing agent discharge.

[0055] Thus, by providing an energy storage battery security system OO including a containing space D, a battery management module F, a storage module A, a fire extinguishing cooling and inerting module C, and an exhaust pressure relief module G, the battery management module F can be used to monitor the battery pack failure conditions, such as abnormal voltage and current, temperature increase, and other functions to determine the signs of thermal runaway. The battery management module F is used as a control module to control the opening and closing of various modules. Precise cooling of the thermal runaway object is performed at the initial stage of thermal runaway. The containing space D is promptly cooled and inerted by fire extinguishing to prevent battery reignition and suppress fire spread. This solution can provide early plans to suppress combustible gas explosions and gain sufficient time for the arrival of professional firefighters. This solution omits the detection devices such as smoke sensors, temperature sensors, harmful gas sensors, and combustible gas sensors in new energy fire protection, thereby greatly reducing the fire protection cost while solving the safety problem of lithium ion batteries.

[0056] Please continue to refer to Figures 1 to 10 In an optional embodiment provided by the present disclosure, the containing space D includes a plurality of energy storage modules E, and the fire extinguishing cooling and inerting module C includes a first fire extinguishing cooling and inerting module C1 and / or a second fire extinguishing cooling and inerting module C2. The first fire extinguishing cooling and inerting module C1 is located in each energy storage module E, and the second fire extinguishing cooling and inerting module C2 is located in the containing space D and outside the energy storage module E.

[0057] In an optional embodiment provided in the present disclosure, the accommodation space D includes a plurality of energy storage modules E, the fire extinguishing, cooling and inerting module C only includes the first fire extinguishing, cooling and inerting module C1, and the first fire extinguishing, cooling and inerting module C1 is located in each energy storage module E; in another optional embodiment provided in the present disclosure, the accommodation space D includes a plurality of energy storage modules E, the fire extinguishing, cooling and inerting module C includes the first fire extinguishing, cooling and inerting module C1 and the second fire extinguishing, cooling and inerting module C2, the first fire extinguishing, cooling and inerting module C1 is located in each energy storage module E, the second fire extinguishing, cooling and inerting module C2 is located in the accommodation space D and outside the energy storage module E; in still another optional embodiment provided in the present disclosure, the accommodation space D includes a plurality of energy storage modules E, the fire extinguishing, cooling and inerting module C only includes the second fire extinguishing, cooling and inerting module C2, and the second fire extinguishing, cooling and inerting module C2 is located in the accommodation space D and outside the energy storage module E.

[0058] Specifically, there are a plurality of energy storage modules E arranged in an array inside the accommodation space D, the fire extinguishing, cooling and inerting module C in the energy storage battery security system 00 includes the first fire extinguishing, cooling and inerting module C1, the first fire extinguishing, cooling and inerting module C1 is located inside each independent energy storage module E, for cooling and cooling the battery in the energy storage module E at the initial stage of thermal runaway through the fire extinguishing, cooling and inerting module C, and for extinguishing fire in the thermal runaway fire, and for extinguishing, cooling and inerting the energy storage module E through the heat absorption and gasification of the sprayed fire extinguishing agent; the fire extinguishing, cooling and inerting module C includes the second fire extinguishing, cooling and inerting module C2, the second fire extinguishing, cooling and inerting module C2 is located inside the accommodation space D and outside the energy storage module E, for extinguishing, cooling and inerting the whole accommodation space D through the heat absorption and gasification of the sprayed fire extinguishing agent to suppress the spread of fire at the occurrence stage of the thermal runaway fire; in this way, through the linkage of the first fire extinguishing, cooling and inerting module C1 and the second fire extinguishing, cooling and inerting module C2, the cooling and cooling intervention at the initial stage of thermal runaway and the fire extinguishing, cooling and inerting in the whole process of thermal runaway fire can be realized; by setting different fire extinguishing, cooling and inerting modules C, the energy storage module E and the non-energy storage module E space can be distinguished, and the thermal runaway part can be precisely cooled in a targeted manner.

[0059] In an optional embodiment provided in the present disclosure, the conveying module B comprises a first conveying module B1 and / or a second conveying module B2, and the fire extinguishing, cooling and inerting module C is connected to the storage module A through the conveying module B; in an optional embodiment provided in the present disclosure, the conveying module B only comprises the first conveying module B1, and the first fire extinguishing, cooling and inerting module C1 is connected to the storage module A through the first conveying module B1; in another optional embodiment provided in the present disclosure, the conveying module B comprises the first conveying module B1 and the second conveying module B2, the first fire extinguishing, cooling and inerting module C1 is connected to the storage module A through the first conveying module B1, and the second fire extinguishing, cooling and inerting module C2 is connected to the storage module A through the second conveying module B2; in still another optional embodiment provided in the present disclosure, the conveying module B only comprises the second conveying module B2, and the second fire extinguishing, cooling and inerting module C2 is connected to the storage module A through the second conveying module B2.

[0060] Specifically, the conveying pipeline B in the energy storage battery security and protection system OO can comprise the first conveying module B1, the first conveying module B1 is connected to the first fire extinguishing, cooling and inerting module C1 and the storage module A, that is, the first conveying module B1 is used for conveying the fire extinguishing agent into the energy storage module E in the containing space D; the conveying pipeline B can comprise the second conveying module B2, the second conveying module B2 is connected to the second fire extinguishing, cooling and inerting module C2 and the storage module A, that is, the second conveying module B2 is used for conveying the fire extinguishing agent into the containing space D, in this way, through two independently arranged conveying modules B, the heat runaway battery in the energy storage module E can be precisely cooled and cooled, and when the heat runaway fire occurs, the spraying amount of the fire extinguishing agent can be increased through the cooperation of the two conveying modules B, the double fire extinguishing, cooling and inerting of the inside and outside of the energy storage module E can be realized, and the fire extinguishing efficiency can be improved.

[0061] Please continue to refer to Figures 1 to 10 In an optional embodiment provided in the present disclosure, the first conveying module B1 is arranged as a circulating pipeline or a non-circulating pipeline, and the second conveying module B2 is a non-circulating pipeline.

[0062] Specifically, the first delivery module B1 is connected with the first fire extinguishing cooling and inerting module C1 and the storage module A. The first delivery module B1 is a closed or open circulation pipeline. The first delivery pipeline B1 is used to deliver the fire extinguishing agent in the storage module A to the first fire extinguishing cooling and inerting module C1 in the energy storage module E in the early stage of thermal runaway. The first fire extinguishing cooling and inerting module C1 cools the thermal runaway battery by heat conduction or the like. After the early warning of thermal runaway is removed, the fire extinguishing agent returns to the storage module A through the open or closed circulation loop of the first delivery module B1 to form a cycle. In an optional embodiment provided by the present disclosure, when the first delivery module B1 is a closed circulation pipeline, the fire extinguishing agent in the storage module A is delivered to the plurality of energy storage modules E in the containing space D through the first delivery module B1. At this time, the fire extinguishing agent only exists in the first delivery module B1. The fire extinguishing agent delivered to the plurality of energy storage modules E returns to the storage module A through the closed circulation pipeline of the first delivery module B1. In another optional embodiment provided by the present disclosure, when the first delivery module B1 is an open circulation pipeline, the fire extinguishing agent in the storage module A is delivered to the plurality of energy storage modules E in the containing space D through the first delivery module B1. The fire extinguishing agent is sprayed into each energy storage module E through the first fire extinguishing cooling and inerting module C1 in each energy storage module E. The fire extinguishing agent sprayed into each energy storage module E returns to the storage module A through the open circulation pipeline of the recovery member and the recovery pipeline.

[0063] In some embodiments, when the first delivery module B1 is an open circulation pipeline, the first delivery module B1 can include an internal delivery pipeline and a recovery pipeline. One end of the internal delivery pipeline is in communication with the storage module A. One end of the recovery pipeline is also in communication with the storage module A. Thus, the fire extinguishing agent in the storage module A can enter the internal delivery pipeline. The fire extinguishing agent in the recovery pipeline can flow back to the storage module A.

[0064] The delivery module B can further include a recovery device. The recovery device can drive the fire extinguishing agent to flow back to the storage module A. Thus, it is beneficial to improve the ability of the system to recover the fire extinguishing agent.

[0065] In some embodiments, the first fire extinguishing cooling and inerting module C1 can include an internal spraying member and a recovery member. The internal spraying member and the recovery member are both arranged in the containing space D and both located in the interior of the energy storage module E. The internal spraying member is connected with the other end of the internal delivery channel, so that the fire extinguishing agent stored in the storage module A can flow to the internal spraying member through the internal delivery channel, so that the fire extinguishing agent can be sprayed into the energy storage module E through the internal spraying member, for fire extinguishing of the interior of the energy storage module E.

[0066] The recovery member is connected with the other end of the recovery pipeline. Specifically, since the energy storage module E is a closed space, after the extinguishing agent is cooled or extinguished, the extinguishing agent can change from solid, liquid or gaseous state to gaseous or liquid-gaseous state. After heat absorption, the extinguishing agent can flow back into the storage module A through the recovery pipeline under the driving of the recovery device through the recovery member, so that the extinguishing agent can be recovered, which is conducive to reducing the waste of the extinguishing agent and thus reducing the cost.

[0067] In some embodiments, the first fire extinguishing cooling and inerting module C1 can be located at the outer periphery of the energy storage module E. In this way, the recovery member can directly recover the extinguishing agent discharged from the energy storage module E, and can avoid entering the inside of the energy storage module E, which is conducive to improving the applicability of the system.

[0068] The outer periphery and the inside of the energy storage module E can be provided with the first fire extinguishing cooling and inerting module C1 and the recovery member. In this way, the fire-fighting capability of the energy storage battery safety protection system OO can be improved to realize effective recycling of the extinguishing agent.

[0069] It should be noted that the circulation pipeline means that a plurality of energy storage modules E in a single containing space D are connected in series through the first conveying module B1. Assuming that the containing space D includes only two energy storage modules E, the extinguishing agent in the storage module A is conveyed to the first energy storage module E through the first conveying module B1, and then conveyed from the first energy storage module E to the second energy storage module E through the first conveying module B1. The extinguishing agent in the second energy storage module E is circulated to the storage module A through the first conveying module B1 in a closed manner to realize effective circulation of the extinguishing agent. Alternatively, the extinguishing agent in the storage module A is conveyed to the first energy storage module E through the first conveying module B1, a part of the extinguishing agent is discharged into the first energy storage module E through the first fire extinguishing cooling and inerting module C1 in the first energy storage module E, and the other part of the extinguishing agent is conveyed from the first energy storage module E to the second energy storage module E through the first conveying module B1 and discharged into the second energy storage module E through the first fire extinguishing cooling and inerting module C1 in the second energy storage module E. The extinguishing agent discharged into the energy storage module E can be recycled to the next containing space D through the recovery member and the recovery pipeline, and then recycled to the storage module A, realizing integrated circulation of extinguishing agent cooling and recycling.

[0070] In an optional embodiment provided by the present disclosure, the plurality of accommodation spaces D are connected in parallel, and the plurality of energy storage modules E in a single accommodation space D are connected in parallel through the first conveying module B1. Assuming that there are only two energy storage modules E in the accommodation space D, the fire extinguishing agent in the storage module A is simultaneously conveyed to the plurality of accommodation spaces D through the first conveying module B1, and the fire extinguishing agent conveyed to the plurality of accommodation spaces D is simultaneously conveyed to the two energy storage modules E in each accommodation space D through the first conveying module B1, and the fire extinguishing agent in each accommodation space D is simultaneously recovered to the storage module A through the closed circulation pipeline formed by the first conveying module B1. Alternatively, the fire extinguishing agent in the storage module A is simultaneously conveyed to the plurality of accommodation spaces D through the first conveying module B1, the fire extinguishing agent conveyed to the plurality of accommodation spaces D is simultaneously conveyed to the energy storage modules E in each accommodation space D through the first conveying module B1, the fire extinguishing agent is simultaneously sprayed into each energy storage module E through the first fire extinguishing cooling and inerting module C1 in each energy storage module E, and the fire extinguishing agent sprayed into each energy storage module E can be simultaneously recovered to the storage module A through the recovery member and the recovery pipeline in an open circulation manner, so as to realize the integrated circulation of fire extinguishing agent cooling and recovery.

[0071] In an optional embodiment provided by the present disclosure, the plurality of accommodation spaces D are connected in parallel, and the plurality of energy storage modules E in a single accommodation space D are connected in parallel through the first conveying module B1. Assuming that there are only two energy storage modules E in the accommodation space D, the fire extinguishing agent in the storage module A is simultaneously conveyed to the plurality of accommodation spaces D through the first conveying module B1, and the fire extinguishing agent conveyed to the plurality of accommodation spaces D is simultaneously conveyed to the two energy storage modules E in each accommodation space D through the first conveying module B1, and the fire extinguishing agent in each accommodation space D is simultaneously recovered to the storage module A through the closed circulation pipeline formed by the first conveying module B1. Alternatively, the fire extinguishing agent in the storage module A is simultaneously conveyed to the plurality of accommodation spaces D through the first conveying module B1, the fire extinguishing agent conveyed to the plurality of accommodation spaces D is simultaneously conveyed to the energy storage modules E in each accommodation space D through the first conveying module B1, the fire extinguishing agent is simultaneously sprayed into each energy storage module E through the first fire extinguishing cooling and inerting module C1 in each energy storage module E, and the fire extinguishing agent sprayed into each energy storage module E can be simultaneously recovered to the storage module A through the recovery member and the recovery pipeline in an open circulation manner, so as to realize the integrated circulation of fire extinguishing agent cooling and recovery.

[0072] It can be understood that the above is only an example and does not represent the actual number of energy storage modules E in the storage space D. For example, the number of energy storage modules E in a single storage space D can be 3, 4, 5, and so on. Here, they are not listed one by one, and the specific actual number is subject to the actual situation. As long as the first conveying module B1 between each energy storage module E is connected in one or several ways of series, parallel, series-parallel, it is acceptable.

[0073] The first conveying module B1 is also used to convey the fire extinguishing agent in the storage module A to the first fire extinguishing cooling and inerting module C1 in the energy storage module E during the thermal runaway fire occurrence period. When the thermal runaway fire occurs, the first fire extinguishing cooling and inerting module C1 sprays the fire extinguishing agent, the fire extinguishing agent absorbs heat and vaporizes, and diffuses to the inside of the energy storage module E to achieve fire extinguishing, cooling and inerting of the energy storage module E.

[0074] The second conveying module B2 is connected with the second fire extinguishing cooling and inerting module C2 and the storage module A. The second conveying module B2 is a non-circulating pipeline. The second conveying module B2 is used to convey the fire extinguishing agent in the energy storage module to the second fire extinguishing cooling and inerting module C2 in the storage space D outside the energy storage module E during the thermal runaway fire occurrence period. The second fire extinguishing cooling and inerting module C2 sprays the fire extinguishing agent, the fire extinguishing agent absorbs heat and vaporizes, and diffuses to the inside of the storage space D to achieve fire extinguishing, cooling and inerting of the entire storage space D.

[0075] In this way, the fire extinguishing agent used for cooling the energy storage module E at the initial stage of thermal runaway can be recycled to the storage module A through the first conveying module B1, which is a circulating loop, to achieve recycling of the fire extinguishing agent and reduce the temperature control cost. Through the synergistic effect of the first conveying module B1 and the second conveying module B2, the energy storage module E is synergistically cooled, fire extinguished and inerted, the fire extinguishing efficiency is improved, and the concentration of flammable gas is reduced.

[0076] Please continue to refer to Figures 1 to 10 In an optional embodiment provided by the present disclosure, the control valve H includes a first control valve H1 and / or a second control valve H2. The first control valve H1 and the second control valve H2 are respectively electrically connected with the battery management module F. The first control valve H1 is located in the first conveying module B1 and is electrically connected with the battery management module F.

The second control valve H2 is located in the second delivery module B2, and the second control valve H2 is used to receive the second control signal F12 of the battery management module F, and control the opening and closing of the second delivery module B2. In an optional embodiment provided by the present disclosure, when the battery management module F determines that the accommodation space D is in the early stage of thermal runaway by monitoring various indicators such as the concentration of flammable gas, the environmental pressure and the temperature, current and voltage of the battery in the accommodation space D, the battery management module F sends the first control signal F11, the first control signal F11 is received by the first control valve H1 and the first control valve H1 is opened, the first delivery module B1 is opened, and the fire extinguishing agent in the storage module A is delivered to the first fire extinguishing cooling and inerting module C1 through the first delivery module B1 to accurately cool the thermal runaway part in the energy storage module E.

[0078] In another optional embodiment provided by the present disclosure, when the battery management module F determines that the various indicators such as the concentration of flammable gas, the environmental pressure and the temperature, current and voltage of the battery in the accommodation space D exceed the second threshold R2, the battery management module F sends the second control signal F12, the first control valve H1 and the second control valve H2 receive the second control signal F12 and are opened, the first delivery module B1 is opened, the second delivery module B2 is opened, the fire extinguishing agent in the storage module A is delivered to the first fire extinguishing cooling and inerting module C1 in the energy storage module E through the first delivery module B1, the fire extinguishing agent in the storage module A is delivered to the second fire extinguishing cooling and inerting module C2 in the accommodation space D through the second delivery module B2, and the first fire extinguishing cooling and inerting module C1 and the second fire extinguishing cooling and inerting module C2 spray the fire extinguishing agent at the same time, which is used for extinguishing, cooling and inerting the whole accommodation space D.

[0079] In this way, by setting different control valves H on different delivery modules B, the delivery module B can be flexibly and specifically opened according to the thermal runaway state of the accommodation space D, and the effective control of the thermal runaway process can be realized.

[0081] Specifically, the fire extinguishing agent in the energy storage module includes one or more of CO2, N2, Ar, H2O, which are substances existing in the environment, natural and environmentally friendly. Such fire extinguishing agent not only can play a role in cooling and preventing reignition, but also can inert flammable gas in thermal runaway fire; during the thermal runaway fire period, after the heat-absorbing gasification of the fire extinguishing agent, due to its non-toxic and harmless characteristics, the fire extinguishing agent can be directly released into the atmosphere or recycled after the inerting or extinguishing stage is completed by opening the containing space D. In this way, by setting the composition of the fire extinguishing agent to one or more of CO2, N2, Ar, H2O, the green and pollution-free fire extinguishing agent can be achieved, and the dilution and inerting of flammable gas can also be achieved to prevent explosion.

[0082] It should be noted that the fire extinguishing agent can be in one or more of liquid, solid, and gaseous states, and the present disclosure does not limit the form of the fire extinguishing agent, which can be set according to actual needs.

[0084] Specifically, the fire extinguishing, cooling, and inerting module C between the storage module A and the containing space D can be in any combination of series, parallel, or series-parallel; further, the fire extinguishing, cooling, and inerting module C between the storage module A and the energy storage module E in the containing space D can be in any combination of series, parallel, or series-parallel, please refer to Figure 8 The storage module A and the first fire extinguishing, cooling, and inerting module C1 in the containing space D are connected in series through the conveying module B, and the fire extinguishing agent can flow through the conveying module B in series to the first fire extinguishing, cooling, and inerting module C1 in each energy storage module E; when the early warning of thermal runaway is removed, the fire extinguishing agent is recycled to the storage module A through the conveying module B in series. Please refer to Figure 9 The storage module A and the first fire extinguishing, cooling, and inerting module C1 in the containing space D are connected through the parallel conveying module B, and the fire extinguishing agent is conveyed to the first fire extinguishing, cooling, and inerting module C1 in the specific energy storage module E through the parallel conveying module B; when the early warning of thermal runaway is removed, the fire extinguishing agent is recycled to the storage module A from the specific energy storage module E through the parallel conveying module B.

[0085] Figure 13 A linkage control method step diagram of an energy storage battery security system provided by an embodiment of the present disclosure, please refer to Figures 1 to 13In a second aspect, the disclosure provides a linkage control method of an energy storage battery security system. The method is applied to the energy storage battery security system 00 as described above, and comprises the following steps: the battery management module F monitors various indexes in the containing space D, judges the size relationship between the monitored index value and the preset first threshold R1 and second threshold R2, the first threshold R1 is less than the second threshold R2; when the index value is less than or equal to the first threshold R1, the storage module A, the fire extinguishing and cooling inerting module C and the control valve H are not opened.

[0086] When the index value is greater than the first threshold R1 and less than or equal to the second threshold R2, the battery management module F sends a first control signal F11, the storage module A, the first fire extinguishing and cooling inerting module C1 and the first control valve H1 are opened, the fire extinguishing agent in the storage module A enters the energy storage module E along the first conveying module B1, the energy storage module E is cooled, and the fire extinguishing agent in the energy storage module E is circulated to the storage module A along the first conveying module B1 or through the recovery piece and the recovery pipeline.

[0087] When the index value is greater than the second threshold R2, the battery module sends a second control signal F12, the storage module A, the first fire extinguishing and cooling inerting module C1 and the first control valve H1 are opened, the second fire extinguishing and cooling inerting module C2 and the second control valve H2 are opened, the fire extinguishing agent in the storage module A is discharged into the energy storage module E from the first conveying module B1, and the fire extinguishing agent in the storage module A is discharged into the containing space D from the second conveying module B2.

[0088] Specifically, in an optional embodiment provided by the disclosure, the battery management module F in the linkage control fire extinguishing system of the containing space D monitors the concentration of flammable gas, environmental pressure, temperature, voltage and current of the battery and other indexes in the containing space D, compares the detected index value with the preset first threshold R1 or second threshold R2, and judges whether the containing space D is in a thermal runaway state; the first threshold R1 is less than the second threshold R2, for example, the first threshold R1 is a green safety value, and the second threshold R2 is a red alarm value.

[0089] In an optional embodiment provided by the disclosure, when the battery management module F monitors that all index values are below the first threshold R1, it indicates that the battery in the containing space D is in good operating condition, the battery management module F does not send a control signal F1, and the storage module A, the fire extinguishing and cooling inerting module C and the control valve H are not actuated.

[0090] In an optional embodiment provided in the present disclosure, when the battery management module F monitors that at least one index value is between the first threshold R1 and the second threshold R2, and any index value is not greater than R2, the battery management module F determines that the battery in the accommodation space D is in the early stage of thermal runaway, and the battery management module F sends a first control signal F11, only the first control valve H1, the storage module A and the first fire extinguishing cooling and inerting module C1 are opened, and the fire extinguishing agent in the storage module A cools and cools the energy storage module E through the first conveying module B1. When all the index values monitored by the battery management module F decrease below the first threshold R1, the battery management module F stops sending the first control signal F11, and the fire extinguishing agent is circulated to the storage module A through the first conveying module B1 or the recovery member and the recovery pipeline. In this way, the battery thermal runaway in the energy storage module E can be early warned and contained in the early stage.

[0091] In an optional embodiment provided in the present disclosure, when the battery management module F monitors that at least any index value is between the first threshold R1 and the second threshold R2, and the index value monitored by the battery management module F gradually increases but is below the second threshold R2, the battery management module F controls to increase the supply of the fire extinguishing agent in the first fire extinguishing cooling and inerting module C1 to achieve the purpose of large-flow cooling.

[0092] In an optional embodiment provided in the present disclosure, when the at least one indicator value monitored by the battery management module F continues to rise to be greater than the second threshold R2, the battery management module F determines that the battery in the accommodation space D is in a thermal runaway fire occurrence period, and the battery management module F sends out a second control signal F12, the storage module A, the first fire extinguishing and cooling inerting module C1, the first control valve H1 are opened, the second fire extinguishing and cooling inerting module C2, the second control valve H2 are opened, the fire extinguishing agent in the storage module A is transported into the first fire extinguishing and cooling inerting module C1 and the second fire extinguishing and cooling inerting module C2 through the first conveying module B1 and the second conveying module B2, and is sprayed into the energy storage module E in the accommodation space D at the same time, and the concentration of the gaseous fire extinguishing agent in the accommodation space D is increased to above the minimum fire extinguishing concentration standard within a specified time, filling all the space in the accommodation space D, and maintaining this concentration for several minutes, several tens of minutes or several hours, thereby playing a role of fire prevention, fire extinguishing, gas soft isolation, fire spread prevention and anti-reignition for the accommodation space D and the energy storage module E therein. At the same time, the supply of fire extinguishing agent to the first fire extinguishing and cooling inerting module C1 is increased, significantly reducing the abnormal values inside the thermal runaway object (energy storage module E), playing a role of fire prevention, fire extinguishing, cooling, isolation, fire spread prevention and anti-reignition protection for the energy storage module E, and delaying and preventing the fire of the energy storage module E from spreading in the accommodation space D and spreading to other accommodation spaces D around, providing comprehensive and extensive fire protection for the accommodation space D, gaining sufficient time for the arrival of fire fighting professionals, and creating good conditions for the final handling of the fire in the accommodation space D by the fire fighting professionals according to the established plan. After the staff determines that the fire is extinguished and there is no risk of reignition, the door is opened for ventilation to resume production due to the heat absorption characteristics of the fire extinguishing agent at room temperature.

[0094] Specifically, the exhaust pressure relief module G comprises at least one pressure relief device which can be mechanically opened to play a role of exhaust pressure relief for the accommodation space D, and can also be closed, or reciprocatingly opened and closed.

[0095] When the battery management module F monitors that the flammable gas concentration in the containing space D exceeds the second threshold R2, the fire extinguishing agent is sprayed into the containing space D through the above-mentioned working process of spraying the fire extinguishing agent, so as to dilute and replace the flammable gas existing in the containing space D, so that the flammable gas is reduced to a safe concentration. At this time, the fire extinguishing agent sprayed into the containing space D is gasified into a gaseous state due to heat absorption, and the internal pressure of the containing space D is increased. When the internal pressure value of the containing space D exceeds the pressure threshold, the exhaust pressure relief module G opens to release the overpressure gas. When the gas in the containing space D is exhausted to the internal pressure value equal to the pressure threshold, the exhaust pressure relief module G is closed. In this way, the exhaust pressure relief module G is opened and closed according to the internal pressure of the containing space D, so that the dynamic balance of the internal pressure of the containing space D can be realized, and the safety hazard caused by excessive internal pressure can be avoided.

[0096] In an optional embodiment provided in the present disclosure, the fire extinguishing agent in the first fire extinguishing cooling inerting module C1 is in one or more of solid, liquid or gaseous states only when the storage module A, the first fire extinguishing cooling inerting module C1 and the first control valve H1 are opened.

[0097] Specifically, when the battery management module F judges that the containing space D is in the initial stage of thermal runaway, the battery management module F sends a first control signal F11, only the storage module A, the first fire extinguishing cooling inerting module C1 and the first control valve H1 are opened, and the fire extinguishing agent in the storage module A is transported to the first fire extinguishing cooling inerting module C1 through the first conveying module B1 to cool and lower the temperature of the thermal runaway object in the energy storage module E. The first conveying module B1 is a circulating loop, and the fire extinguishing agent in the energy storage module E cools and lowers the temperature of the thermal runaway object through heat conduction.
