[0002] With the rapid development of energy storage technology, energy storage systems are widely used in many industry fields. However, the energy storage devices in the energy storage system will generate heat during long-term use, and the stacking of multiple energy storage devices is relatively dense, so that the heat cannot be fully dissipated, and there is a risk of fire caused by heat accumulation.

[0003] The existing energy storage fire extinguishing system is independently set, that is, each energy storage unit is equipped with a set of fire extinguishing system. Once an abnormality of the energy storage unit is detected, the corresponding fire extinguishing system is started to extinguish the fire. However, this way of configuring a set of fire extinguishing system for each energy storage unit has the problem of high cost. SUMMARY

[0004] In view of the above problems, the present application provides a fire extinguishing system, an energy storage power station thereof, a fire extinguishing control method and an electronic device, which can solve the problem of high cost caused by the current energy storage system in which each energy storage unit is equipped with a set of fire extinguishing system.

[0005] In a first aspect, the present application provides a fire extinguishing system, which is used for fire extinguishing of an energy storage system; the energy storage system includes N energy storage units; the fire extinguishing system includes a collection control unit and a fire extinguishing pipe network; the fire extinguishing pipe network includes a main pipe and N branch pipes; two ends of each branch pipe are connected to the main pipe and one energy storage unit, respectively; the N branch pipes are respectively provided with fire extinguishing agent containers for storing fire extinguishing agents; wherein N is an integer greater than or equal to 2; the collection control unit is used for collecting environmental characteristic information of each energy storage unit, and after determining that there is a target energy storage unit that needs fire extinguishing according to the environmental characteristic information of each energy storage unit, controlling the fire extinguishing agents in the fire extinguishing agent containers in the fire extinguishing pipe network to be sprayed out to extinguish the target energy storage unit.

[0006] In the technical scheme of the present application, the present application connects the main pipe and one energy storage unit through each branch pipe of the fire extinguishing pipe network, and sets the fire extinguishing agent containers for storing fire extinguishing agents on the branch pipes, so that after the collection control unit determines that there is a target energy storage unit that needs fire extinguishing according to the environmental characteristic information of the energy storage unit, the fire extinguishing agents in the fire extinguishing agent containers in the fire extinguishing pipe network are controlled to be sprayed out to extinguish the target energy storage unit that needs fire extinguishing. Thus, the fire extinguishing management and control of multiple energy storage units are realized through the simple fire extinguishing pipe network, and the problem of high cost caused by the design of one fire extinguishing system for each energy storage unit in the existing energy storage system is solved, and the fire extinguishing cost of the energy storage system is reduced.

[0007] In some embodiments, the collection control unit is specifically configured to control the fire-fighting agent in the fire-fighting agent container of the branch pipe corresponding to the target energy storage unit to be sprayed into the target energy storage unit to perform fire fighting on the target energy storage unit. In this embodiment, the collection control unit controls the fire-fighting agent in the fire-fighting agent container of the branch pipe corresponding to the target energy storage unit to perform fire fighting, so as to quickly respond to the fire fighting demand.

[0008] In some embodiments, the fire-fighting agent container of each branch pipe is provided with a first valve between the corresponding energy storage unit, and the collection control unit communicates with each first valve. The collection control unit is specifically configured to control the first valve of the branch pipe corresponding to the target energy storage unit to be opened to control the fire-fighting agent in the fire-fighting agent container of the branch pipe corresponding to the target energy storage unit to be sprayed into the target energy storage unit. In this embodiment, the first valve is controlled to be opened and closed to achieve fire fighting of the target energy storage unit, so as to simplify the fire fighting control process and achieve quick fire fighting response.

[0009] In some embodiments, the collection control unit is specifically configured to control the fire-fighting agent in the fire-fighting agent container of the branch pipe corresponding to the target energy storage unit and the branch pipe corresponding to other energy storage units to be sprayed into the target energy storage unit to perform fire fighting on the target energy storage unit. In this embodiment, in addition to the fire-fighting agent in the fire-fighting agent container corresponding to the target energy storage unit, the fire-fighting agent in the fire-fighting agent container corresponding to other energy storage units can also be called to achieve the fire fighting ability of the fire fighting system designed in this solution for the fire situation that cannot be extinguished by a single fire-fighting pipe, and improve the reliability and processing capacity of the fire fighting system.

[0010] In some embodiments, the collection control unit is specifically configured to control the fire-fighting agent in the fire-fighting agent container of the branch pipe corresponding to the target energy storage unit to be sprayed into the target energy storage unit, and start a first timing; obtain the fire-fighting time of the fire-fighting agent container corresponding to the target energy storage unit; wherein the fire-fighting time represents the time during which the fire-fighting agent in the fire-fighting agent container corresponding to the target energy storage unit can be continuously sprayed; if it is determined that the real-time environmental feature information of the target energy storage unit does not meet the fire-fighting stop condition when the first timing reaches the fire-fighting time, the fire-fighting agent in the fire-fighting agent container of the branch pipe corresponding to other energy storage units except the target energy storage unit is controlled to be sprayed into the target energy storage unit. In this embodiment, the time is used to determine whether the fire-fighting agent in the fire-fighting agent container corresponding to the target energy storage unit is about to be exhausted, so as to call the fire-fighting agent in the fire-fighting agent container of other energy storage units according to the exhaustion condition, and avoid the problem of fire growth caused by the delay of the fire-fighting agent, and improve the timeliness of fire fighting.

[0011] In some embodiments, the other energy storage units except the target energy storage unit include energy storage units adjacent to the target energy storage unit.

[0012] In some embodiments, the collection control unit is further configured to: start a second timing after the fire-fighting agent container corresponding to the nearest neighbor energy storage unit of the target energy storage unit performs fire-fighting on the target energy storage unit; if the real-time environmental characteristic information of the target energy storage unit meets the fire-fighting termination condition before the second timing reaches the fire-fighting time, stop the fire-fighting; and if the real-time environmental characteristic information of the target energy storage unit does not meet the fire-fighting termination condition when the second timing reaches the fire-fighting time, control the fire-fighting agent container corresponding to the next nearest neighbor energy storage unit of the target energy storage unit to spray the fire-fighting agent into the target energy storage unit. This embodiment reduces the calling time of the fire-fighting agent by calling the fire-fighting agent of the fire-fighting agent container corresponding to the nearest neighbor and the next nearest neighbor energy storage unit of the target energy storage unit, thereby improving the response speed of the fire-fighting.

[0013] In some embodiments, a first valve is arranged between each branch pipe fire-fighting agent container and the corresponding energy storage unit, and a second valve is arranged between each branch pipe fire-fighting agent container and the main pipe.

This embodiment simplifies the structure of the fire-fighting system and saves the cost of the fire-fighting system by arranging the first valve and the second valve on each branch pipe, thereby realizing the spraying of the fire-fighting agent of the target energy storage unit and the calling of the fire-fighting agent of other energy storage units through the simple opening and closing of the valves.

DETAILED DESCRIPTION

[0047] The embodiments of the technical scheme of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and therefore only serve as examples, but cannot limit the protection scope of the present application.

[0048] With the rapid development of energy storage technology, energy storage systems are widely used in many industry fields. However, the energy storage devices in the energy storage system will generate heat during long-term use, and the stacking of multiple energy storage devices is relatively dense, so the heat cannot be fully dissipated, and there is a risk of fire caused by heat accumulation. Therefore, the current energy storage system is usually configured with a fire fighting system to reduce the risk of fire.

[0049] The existing energy storage fire fighting system is independently set, that is, each energy storage unit is equipped with a set of fire fighting system. Once the energy storage unit is detected to be abnormal, the corresponding fire fighting system is started to extinguish the fire. However, this way of configuring a set of fire fighting system for each energy storage unit has the problem of high cost.

[0050] The present application designs a fire fighting system, an energy storage power station, a fire fighting control method and an electronic device. The fire fighting agents of each energy storage unit are connected through the fire fighting pipe network. In this way, when there is a fire risk in any one or more energy storage units, the fire fighting agent can be delivered to the energy storage unit with fire risk through the fire fighting pipe network, thereby simplifying the fire fighting system of the energy storage system and achieving a more ideal fire extinguishing effect. In addition, in the case that the fire fighting agent of a certain fire fighting agent container is insufficient, the fire fighting agent of the fire fighting agent container corresponding to other energy storage units can be called to participate in fire fighting, thereby improving the fire fighting capability.

[0051] According to some embodiments of the present application, a fire-fighting system 1 for fire-fighting of an energy storage system 2 is provided, as shown in Figure 1 The energy storage system 2 includes N energy storage units A, and the fire-fighting system 1 includes a collection control unit 10 and a fire-fighting pipe network 20, which includes a main pipe 210 and N branch pipes 220, two ends of each branch pipe 220 are connected to the main pipe 210 and one energy storage unit A respectively, and fire-fighting agent containers 230 for storing fire-fighting agent are arranged on the N branch pipes 220, wherein each fire-fighting agent container 230 stores a fixed amount of fire-fighting agent, and N is an integer greater than or equal to 2.

[0052] As a possible implementation, the fire-fighting agent containers 230 for storing fire-fighting agent arranged on the N branch pipes 220 can be one fire-fighting agent container 230 arranged on each of the N branch pipes 220, as shown in Figure 1 As another possible implementation, the fire-fighting agent containers 230 for storing fire-fighting agent arranged on the N branch pipes 220 can also be fire-fighting agent containers 230 arranged on part of the N branch pipes 220, as shown in Figure 2

[0053] ​The fire-fighting system 1 designed above, the collection control unit 10 can collect the environmental characteristic information of each energy storage unit A in the energy storage system 2, wherein the environmental characteristic information can include one or more of the temperature information, smoke information and combustible gas information of the energy storage unit environment, and then the collection control unit 10 can determine whether there is a target energy storage unit that needs to be fire-fought in the plurality of energy storage units according to the environmental characteristic information of each energy storage unit. If it is determined that there is a target energy storage unit that needs to be fire-fought, the collection control unit 10 controls the fire-fighting agent in the fire-fighting agent container 230 of the fire-fighting pipe network 20 to be sprayed out to fire-fight the target energy storage unit. Wherein, the present scheme can set a safety threshold value in advance, such as a temperature safety threshold value, a smoke / combustible gas concentration safety threshold value, etc., and the collection control unit can compare the obtained environmental characteristic information of each energy storage unit with the corresponding safety threshold value. If the environmental characteristic information exceeds the safety threshold value, the energy storage unit with the environmental characteristic information exceeding the safety threshold value is determined to be the target energy storage unit that needs to be fire-fought. For example, the present scheme can compare the environmental temperature of each energy storage unit with the corresponding temperature safety threshold value. If the environmental temperature exceeds the corresponding temperature safety threshold value, the energy storage unit with the environmental temperature exceeding the temperature safety threshold value is determined to be the target energy storage unit that needs to be fire-fought. Specifically, the present scheme can set a unique identifier for each energy storage unit in advance. For example, N energy storage units can be A1, A2, A3, …, AN-1 and AN respectively. The collection control unit can also correspondingly obtain the unique identifier of the energy storage unit corresponding to the environmental characteristic information under the condition of the environmental characteristic information, and bind the unique identifier with the corresponding environmental characteristic information, so as to obtain the unique identifier of the environmental characteristic information exceeding the safety threshold value, and further determine that there is a target energy storage unit that needs to be fire-fought.

[0054] Wherein, in the case that one fire-fighting agent container 230 is arranged on each branch pipe 220 in the N branch pipes 220, as one possible implementation manner, the collection control unit 10 can control the fire-fighting agent in the fire-fighting agent container 230 on the branch pipe 220 corresponding to the target energy storage unit to be sprayed out; as another possible implementation manner, in addition to controlling the fire-fighting agent in the fire-fighting agent container 230 on the branch pipe 220 corresponding to the target energy storage unit to be sprayed out, the collection control unit 10 can also control the fire-fighting agent containers 230 corresponding to other energy storage units as fire-fighting agent supplements.

[0055] The fire-fighting system 1 has the advantages that: the fire-fighting system 1 is designed, the fire-fighting agent container for storing the fire-fighting agent is arranged on each branch pipe of the fire-fighting pipe network, and the fire-fighting agent in the fire-fighting agent container is sprayed out under the control of the acquisition control unit according to the environmental characteristic information of the energy storage unit, so that the target energy storage unit is fire-fought, the fire-fighting management and control of the multiple energy storage units are realized through the simple fire-fighting pipe network, the problem of high cost caused by the fact that each energy storage unit is designed with a fire-fighting system in the prior art energy storage system is solved, and the fire-fighting cost of the energy storage system is reduced.

[0056] In an optional implementation of the embodiment, the acquisition control unit 10 can control the fire-fighting agent in the fire-fighting agent container 230 on the branch pipe 220 corresponding to the target energy storage unit to be sprayed out, as a possible implementation, the fire-fighting agent in the fire-fighting agent container 230 can be sprayed out through valve control, specifically, as shown in Figure 2 the fire-fighting agent container 230 of each branch pipe 220 in the fire-fighting system is provided with a first valve 240 corresponding to the energy storage unit A, the acquisition control unit 10 communicates with each first valve 240, on this basis, the acquisition control unit 10 can control the first valve 240 of the branch pipe 220 corresponding to the target energy storage unit to be opened, so that the fire-fighting agent container 230 of the branch pipe 220 corresponding to the target energy storage unit is connected to the pipe of the target energy storage unit, so that the fire-fighting agent is sprayed into the target energy storage unit, and the fire-fighting of the target energy storage unit is realized.

[0057] In the embodiment, the unique identifier of each first valve can be established in advance, and then the unique identifier of each energy storage unit is bound to the unique identifier of the first valve on the branch pipe corresponding to the energy storage unit, for example, the target first valve corresponding to the first energy storage unit A1 can be 240A1, and the A1 is bound to the 240A1, so that the corresponding target first valve 240A1 can be controlled in the case that the first energy storage unit A1 is determined as the target energy storage unit.

[0058] In the above embodiment, the acquisition control unit 10 controls the first valve on the branch pipe corresponding to the target energy storage unit, so that the fire-fighting agent container 230 of the branch pipe 220 corresponding to the target energy storage unit is connected to the pipe of the target energy storage unit, so that the fire-fighting control of the target energy storage unit is realized simply.

[0059] In an optional implementation of the embodiment, when the fire of the target energy storage unit is large, the fire extinguishing agent stored in the fire extinguishing agent container 230 on the branch pipe corresponding to the target energy storage unit cannot meet the fire demand. In this case, the following scheme is designed: the collection control unit 10 can also control the fire extinguishing agent in the fire extinguishing agent containers of the branch pipes corresponding to the target energy storage unit and other energy storage units to be sprayed into the target energy storage unit to extinguish the fire of the target energy storage unit.

[0060] As a specific implementation, the collection control unit 10 can first control the fire extinguishing agent in the fire extinguishing agent container 230 of the branch pipe 220 corresponding to the target energy storage unit to be sprayed into the target energy storage unit to extinguish the fire, and then the collection control unit 10 starts the first timing. If it is determined that the real-time environmental feature information of the target energy storage unit does not meet the fire extinguishing stop condition when the first timing reaches the fire extinguishing time, it means that the fire extinguishing agent stored in the fire extinguishing agent container 230 on the branch pipe 220 corresponding to the target energy storage unit has almost been sprayed out, but the fire of the target energy storage unit has not been controlled. On this basis, the collection control unit controls the fire extinguishing agent in the fire extinguishing agent containers of the branch pipes corresponding to other energy storage units except the target energy storage unit to be sprayed into the target energy storage unit, so as to further extinguish the fire.

[0061] Among them, the fire extinguishing time described in the foregoing represents the time during which the fire extinguishing agent in the fire extinguishing agent container corresponding to the target energy storage unit can be continuously sprayed. Specifically, the fire extinguishing time can be obtained by calculating the difference between the first time and the preset delay time. The first time is obtained by calculating the quotient of the fire extinguishing agent capacity of the target energy storage unit and the fire extinguishing agent spraying speed. The preset delay time is set according to the experience value, and specifically can be determined according to the time for the fire extinguishing agent in the fire extinguishing agent container farthest from the target energy storage unit to reach the position of the target energy storage unit.

[0062] In the above implementation, after the collection control unit controls the fire extinguishing agent in the fire extinguishing agent container 230 of the branch pipe 220 corresponding to the target energy storage unit to be sprayed into the target energy storage unit to extinguish the fire, the first timing is started. When the first timing reaches the fire extinguishing time, if the real-time environmental feature information of the target energy storage unit does not meet the fire extinguishing stop condition, that is, the fire has not been controlled, the collection control unit controls the fire extinguishing agent in the fire extinguishing agent containers of the branch pipes corresponding to other energy storage units except the target energy storage unit to be sprayed into the target energy storage unit, so as to further extinguish the fire, thereby improving the reliability of the energy storage system fire extinguishing.

[0063] In an optional implementation of the embodiment, the foregoing describes that the energy storage system includes N energy storage units, and the fire extinguishing agent containers of the energy storage units other than the target energy storage unit can be selected by the following method. Specifically, the acquisition control unit can first control the fire extinguishing agent containers corresponding to the energy storage units nearest to the target energy storage unit to perform fire extinguishing on the target energy storage unit, and then starts a second timer. If the real-time environmental characteristic information of the target energy storage unit meets the fire extinguishing stop condition before the second timer reaches the fire extinguishing time, it indicates that the fire of the target energy storage unit has been controlled, and the acquisition control unit 10 then controls the fire extinguishing to stop.

[0064] If the acquisition control unit 10 determines that the real-time environmental characteristic information of the target energy storage unit does not meet the fire extinguishing stop condition when the second timer reaches the fire extinguishing time, the acquisition control unit 10 controls the fire extinguishing agent in the fire extinguishing agent containers of the branch pipes corresponding to the energy storage units next to the target energy storage unit to be sprayed into the target energy storage unit, thereby achieving further fire extinguishing.

[0065] It should be noted that the acquisition control unit 10 calls the fire extinguishing agent in the fire extinguishing agent containers of the energy storage units other than the target energy storage unit from near to far by the above method, until the real-time environmental characteristic information of the target energy storage unit meets the fire extinguishing stop condition.

[0066] As a specific implementation, as shown in Figure 3 The fire extinguishing system 1 can further include a second valve 250 arranged between the fire extinguishing agent container 230 of each branch pipe 220 and the main pipe 210. On this basis, the acquisition control unit can control the second valve 250 corresponding to the target energy storage unit to be opened, and control the second valve 250 corresponding to the energy storage unit adjacent to the target energy storage unit to be opened, so as to control the fire extinguishing agent container 230 corresponding to the energy storage unit adjacent to the target energy storage unit to enter the branch pipe 220 corresponding to the target energy storage unit, thereby performing fire extinguishing on the target energy storage unit.

[0067] In this case, the present solution can establish a unique identifier for each first valve and second valve in advance, and then bind the unique identifier of each energy storage unit with the unique identifiers of the first valve and second valve on the branch pipe corresponding to the energy storage unit. For example, the target first valve corresponding to the first energy storage unit A1 can be 240A1, and the target second valve can be 250A1. The present solution binds A1 with 240A1 and 250A1, so that when the first energy storage unit A1 is determined as the target energy storage unit, the corresponding target first valve 240A1 and target second valve 250A1 can be controlled.

[0068] For example, as shown in Figure 4As shown, the target energy storage unit is the first energy storage unit A1, and the second energy storage unit A2 is the energy storage unit adjacent to the first energy storage unit A1. On this basis, the acquisition control unit 10 first controls the target first valve 240A1 of the first energy storage unit A1 to open, sprays the fire-fighting agent in the fire-fighting agent container 230 corresponding to the first energy storage unit A1 into the first energy storage unit A1 for fire fighting, and starts the first timing. During the first timing, the acquisition control unit 10 acquires the real-time environmental characteristic information of the first energy storage unit A1, and judges whether the real-time environmental characteristic information meets the fire-fighting stop condition. If the real-time environmental characteristic information does not meet the fire-fighting stop condition when the first timing reaches the fire-fighting time, the acquisition control unit 10 controls the target second valve 250A1 corresponding to the first energy storage unit A1 to open, and controls the adjacent second valve 250A2 corresponding to the second energy storage unit A2 to open, so as to control the fire-fighting agent in the fire-fighting agent container 230 corresponding to the second energy storage unit A2 to pass through the branch pipe corresponding to the second energy storage unit A2, the main pipe 210 and the branch pipe corresponding to the first energy storage unit A1, and then be sprayed into the first energy storage unit A1 for fire fighting. In this case, the acquisition control unit 10 starts the second timing. During the second timing, the acquisition control unit 10 acquires the real-time environmental characteristic information of the first energy storage unit A1, and judges whether the real-time environmental characteristic information meets the fire-fighting stop condition. If the real-time environmental characteristic information meets the fire-fighting stop condition when the second timing does not reach the fire-fighting time, all the valves are controlled to be closed, and then the fire fighting is controlled to be stopped. If the real-time environmental characteristic information still does not meet the fire-fighting stop condition when the second timing reaches the fire-fighting time, the adjacent second valve 250A2 corresponding to the second energy storage unit A2 is controlled to be closed, and the calling second valve 250A3 corresponding to the third energy storage unit A3 is controlled to be opened, so as to control the fire-fighting agent in the fire-fighting agent container 230 corresponding to the third energy storage unit A3 to pass through the branch pipe corresponding to the third energy storage unit A3, the main pipe 210 and the branch pipe corresponding to the first energy storage unit A1, and then be sprayed into the first energy storage unit A1 for fire fighting.

[0069] It should be noted that, since each branch pipe 220 in the fire-fighting system is provided with a second valve 250, the acquisition control unit 10 can open the second valve 250 on the branch pipe of the target energy storage unit and the called energy storage unit to call the fire-fighting agent corresponding to other energy storage units.

[0070] In the above embodiment, the fire-fighting agent in the fire-fighting agent container corresponding to the target energy storage unit can be used, and the fire-fighting agent in the fire-fighting agent container corresponding to other energy storage units can also be called, so that the fire-fighting of the larger fire can be safely performed, and the reliability of the fire fighting is improved.

[0071] In an optional embodiment of the present embodiment, as shown in FIG. 6, the fire-fighting system further comprises a third energy storage unit A3, and the third energy storage unit A3 is provided with a calling second valve 250A3. Figure 5As shown, the fire-fighting system designed by the scheme can further be provided with a booster pump 30 and a pressure sensor 40 on the main pipeline 210, and the acquisition control unit 10 is configured to communicate with the booster pump 30 and the pressure sensor 40 respectively. On this basis, the acquisition control unit 10 can obtain the pressure value of the main pipeline 210 collected by the pressure sensor 40, and control the booster pump 30 to start in the case that the pressure value of the main pipeline 210 is lower than the preset pressure value.

[0072] In the above embodiment, the scheme monitors the pressure value of the main pipeline 210 through the pressure sensor 40, and controls the booster pump 30 to start in the case that the pressure value of the main pipeline 210 is lower than the preset pressure value, so as to pressurize the main pipeline 210 through the booster pump 30, thereby ensuring the ejection speed of the fire-fighting agent and providing necessary guiding force for the ejection of the fire-fighting agent, so that as much fire-fighting agent as possible in the fire-fighting agent container 230 enters the fire-fighting pipe network, and the problems of insufficient fire-fighting agent ejection force or excessive residual caused by excessively low pressure are avoided.

[0073] In an optional embodiment of the present embodiment, as shown in Figure 6 The fire-fighting system designed by the scheme includes a storage device 50, two ends of the storage device 50 are connected with the main pipeline 210 through a first storage branch pipeline 510 and a second storage branch pipeline 520 respectively, the first storage branch pipeline 510 is provided with a first booster pump 60 and a first pressure sensor 70, the second storage branch pipeline 520 is provided with a second booster pump 80 and a second pressure sensor 90, and the acquisition control unit 10 is electrically connected with the first booster pump 60, the second booster pump 80, the first pressure sensor 70 and the second pressure sensor 90 respectively.

[0074] The acquisition control unit 10 is further used for controlling the first booster pump 60 and the second booster pump 80 to start in the case that the target energy storage unit corresponding second valve 250 and the energy storage unit adjacent to the target energy storage unit corresponding second valve 250 are opened, so as to timely send the fire-fighting agent in the fire-fighting agent container 230 corresponding to the energy storage unit adjacent to the target energy storage unit into the target energy storage unit, and improve the timeliness and reliability of fire-fighting.

[0075] In an optional embodiment of the present embodiment, as shown in Figure 7 The acquisition control unit 10 can include an acquisition unit 100 and a control unit 101, and the acquisition unit 100 and the control unit 101 are electrically connected. The acquisition unit 100 can include a plurality of temperature sensors and / or smoke sensors and / or combustible gas sensors, and one acquisition unit 100 is arranged in each energy storage unit A. The acquisition unit 100 is used for collecting the environmental characteristic information of the energy storage unit A and transmitting the environmental characteristic information to the control unit 101, and the control unit 101 executes the fire-fighting control process.

[0076] In an optional implementation of the embodiment, the acquisition control unit 10 acquires real-time environmental characteristic information of the target energy storage unit during the fire extinguishing process of the target energy storage unit, determines whether the real-time environmental characteristic information of the target energy storage unit meets the fire extinguishing stop condition, and stops the fire extinguishing if it is determined that the real-time environmental characteristic information of the target energy storage unit meets the fire extinguishing stop condition. The fire extinguishing stop condition can include that each environmental characteristic of the target energy storage unit is reduced to a safety value, for example, the fire extinguishing stop condition can be that the environmental temperature of the target energy storage unit is reduced to below a preset safety temperature, or the environmental smoke / gas concentration of the target energy storage unit is reduced to below a preset concentration value, and the like.

[0077] The application also provides an energy storage power station, as shown in the figure, which comprises an energy storage system 2 and the fire extinguishing system 1 of any of the optional implementations described above. Figure 8

[0078] The energy storage power station designed as above, the present application connects the main pipe and one energy storage unit through each branch pipe of the fire extinguishing pipe network, and sets a fire extinguishing agent container storing fire extinguishing agent on the branch pipe, so that after the acquisition control unit determines the target energy storage unit that needs to be extinguished according to the environmental characteristic information of the energy storage unit, the fire extinguishing agent in the fire extinguishing agent container in the fire extinguishing pipe network is controlled to be sprayed out to extinguish the target energy storage unit that needs to be extinguished, thereby realizing the fire extinguishing management and control of multiple energy storage units through the simple fire extinguishing pipe network, and further solving the problem of high cost caused by the design of one fire extinguishing system for each energy storage unit in the existing energy storage system, thereby reducing the fire extinguishing cost of the energy storage system.

[0079] The application also provides a fire extinguishing control method, which is executed by the acquisition control unit in the fire extinguishing system described above, as shown in the figure, the fire extinguishing control method can be realized by the following method, which comprises: Figure 9

[0080] Step S900: acquiring the environmental characteristic information of each energy storage unit of the energy storage system.

[0081] Step S910: determining whether there is a target energy storage unit that needs to be extinguished in the multiple energy storage units according to the environmental characteristic information of each energy storage unit.

[0082] Step S920: in the case where it is determined that there is a target energy storage unit that needs to be extinguished, controlling the fire extinguishing agent in the fire extinguishing agent container of the fire extinguishing pipe network to be sprayed out to extinguish the target energy storage unit.

[0083] ​​In the above embodiments, the energy storage system and the fire extinguishing system can adopt the energy storage system and the fire extinguishing system as described above, which will not be repeated here. In addition, the energy storage system and the fire extinguishing system can also adopt other energy storage systems and fire extinguishing systems with corresponding functional characteristics in the art. The environmental characteristic information is related information of the environment where the energy storage unit is located, for example, the temperature of the environment where the energy storage unit is located, the smoke concentration of the environment where the energy storage unit is located, and the flammable gas concentration of the environment where the energy storage unit is located, etc. The environmental characteristics referred to above include any one or any combination of the examples. The environmental characteristic information of each energy storage unit can be obtained by collecting relevant sensors arranged in the energy storage unit, for example, by arranging a temperature sensor in the energy storage unit to collect the temperature of the environment where the energy storage unit is located; by arranging a smoke sensor in the energy storage unit to collect the smoke concentration of the environment where the energy storage unit is located; by arranging a flammable gas sensor in the energy storage unit to collect the flammable gas concentration of the environment where the energy storage unit is located.

[0084] In the case of obtaining the environmental characteristic information of each energy storage unit by the above-mentioned method, the collection control unit can determine whether there is a target energy storage unit that needs to be extinguished among the plurality of energy storage units according to the environmental characteristic information of each energy storage unit. Specifically, the present scheme can set safety thresholds in advance, such as temperature safety thresholds, smoke / flammable gas concentration safety thresholds, etc. The collection control unit can compare the obtained environmental characteristic information of each energy storage unit with the corresponding safety threshold. If the environmental characteristic information exceeds the safety threshold, the energy storage unit with the environmental characteristic information exceeding the safety threshold is determined as the target energy storage unit that needs to be extinguished. For example, the present scheme can compare the environmental temperature of each energy storage unit with the corresponding temperature safety threshold. If the environmental temperature exceeds the corresponding temperature safety threshold, the energy storage unit with the environmental temperature exceeding the temperature safety threshold is determined as the target energy storage unit that needs to be extinguished.

[0085] In the case of determining that there is a target energy storage unit that needs to be extinguished, the present scheme can control the fire extinguishing agent in the fire extinguishing agent container of the fire extinguishing pipe network to be sprayed, thereby extinguishing the target energy storage unit.

[0086] The fire extinguishing control method designed above, the present scheme connects the main pipe and an energy storage unit through each branch pipe of the fire extinguishing pipe network, and sets a fire extinguishing agent container storing fire extinguishing agent on the branch pipe, so as to control the fire extinguishing agent in the fire extinguishing agent container of the fire extinguishing pipe network to be sprayed after determining that there is a target energy storage unit that needs to be extinguished according to the environmental characteristic information of the energy storage unit, thereby extinguishing the target energy storage unit that needs to be extinguished. Thus, the fire extinguishing management and control of multiple energy storage units are realized through the simple fire extinguishing pipe network, thereby solving the problem of high cost caused by the design of a fire extinguishing system for each energy storage unit in the existing energy storage system, and reducing the fire extinguishing cost of the energy storage system.

[0087] As a possible implementation, for step S920, the scheme can specifically control the fire extinguishing agent in the fire extinguishing agent container of the branch pipeline corresponding to the target energy storage unit to be sprayed into the target energy storage unit to extinguish the fire of the target energy storage unit. The specific implementation manner is consistent with the foregoing implementation manner one, which will not be described here again. Figure 3 The specific implementation manner is consistent with the foregoing implementation manner one, which will not be described here again.

[0088] As another possible implementation, for step S920, in the case that the fire of the target energy storage unit is large, the fire extinguishing agent in the fire extinguishing agent container of the branch pipeline corresponding to the target energy storage unit cannot control the fire, for this, the scheme can also control the fire extinguishing agent in the fire extinguishing agent container of the branch pipeline corresponding to the target energy storage unit and the fire extinguishing agent container of other energy storage units except the target energy storage unit to be sprayed into the target energy storage unit to extinguish the fire of the target energy storage unit, so that in the case that the fire of the target energy storage unit is large, the timely supplement of the fire extinguishing agent in multiple places can be realized through the fire extinguishing pipe network, and the fire extinguishing reliability is improved.

[0089] Further, the scheme can first control the fire extinguishing agent in the fire extinguishing agent container of the branch pipeline corresponding to the target energy storage unit to be sprayed into the target energy storage unit, and then start the first timing. In the timing process, the control unit acquires the real-time environmental characteristic information of the target energy storage unit, and judges whether the real-time environmental characteristic information meets the fire extinguishing stop condition. If the real-time environmental characteristic information of the target energy storage unit meets the fire extinguishing stop condition in the case that the first timing does not reach the fire extinguishing time, it is indicated that the fire of the target energy storage unit has been controlled, and then the fire extinguishing is stopped.

[0090] If the real-time environmental characteristic information of the target energy storage unit still does not meet the fire extinguishing stop condition in the case that the first timing reaches the fire extinguishing time, the fire extinguishing agent in the fire extinguishing agent container of the branch pipeline corresponding to other energy storage units except the target energy storage unit is controlled to be sprayed into the target energy storage unit, so as to perform supplementary fire extinguishing.

[0091] Specifically, the other energy storage units except the target energy storage unit can include the energy storage units adjacent to the target energy storage unit. For example, the energy storage unit nearest to the target energy storage unit and the energy storage unit next nearest to the target energy storage unit. Wherein, the energy storage unit nearest to the target energy storage unit means the energy storage unit closest to the target energy storage unit, and the energy storage unit next nearest to the target energy storage unit means the energy storage unit second closest to the target energy storage unit.

[0092] On this basis, the scheme can first control the fire-fighting agent containers corresponding to the energy storage units adjacent to the target energy storage unit to spray the fire-fighting agent into the target energy storage unit, and then start a second timing. During the timing, the control unit acquires real-time environmental characteristic information of the target energy storage unit and determines whether the real-time environmental characteristic information meets the fire-fighting stop condition. If the real-time environmental characteristic information of the target energy storage unit still does not meet the fire-fighting stop condition when the second timing reaches the fire-fighting time, the fire-fighting agent containers corresponding to the energy storage units adjacent to the target energy storage unit are controlled to spray the fire-fighting agent into the target energy storage unit. The specific implementation mode has been described in the foregoing fire-fighting system, and will not be repeated here.

[0093] The fire-fighting stop condition described in the foregoing can be that each environmental characteristic of the target energy storage unit is reduced to a safety value. For example, the fire-fighting stop condition can be that the environmental temperature of the target energy storage unit is reduced to below a preset safety temperature, or the environmental smoke / gas concentration of the target energy storage unit is reduced to below a preset concentration value, and the like.

[0094] In an optional implementation mode of the embodiment, in addition to the above-mentioned mode of controlling the fire-fighting of the energy storage system, the scheme can first determine the target number of fire-fighting agent containers required according to the current fire situation of the target energy storage unit, and then control the fire-fighting agent in the target number of fire-fighting agent containers to spray into the target energy storage unit for fire-fighting. During the fire-fighting, the scheme can continuously monitor the real-time environmental characteristic information of the target energy storage unit. Before the fire-fighting agent in the target number of fire-fighting agent containers is sprayed, if the real-time environmental characteristic information of the target energy storage unit still does not meet the fire-fighting stop condition, the fire-fighting agent containers of other energy storage units are sequentially called for fire-fighting as described in the foregoing mode until the real-time environmental characteristic meets the fire-fighting stop condition.

[0095] The fire situation of the target energy storage unit can be determined according to the environmental characteristic information of the target energy storage unit. For example, the scheme can determine the fire situation of the target energy storage unit according to the environmental temperature of the target energy storage unit, or determine the fire situation of the target energy storage unit according to the smoke concentration or the gas concentration of the target energy storage unit. Specifically, taking the temperature as an example, if the environmental temperature of the target energy storage unit is within 20°C of the temperature safety threshold, the fire situation is a first-level fire, and the target number of fire-fighting agent containers corresponding to the first-level fire is 3. If the environmental temperature of the target energy storage unit is within 20°C-50°C of the temperature safety threshold, the fire situation is a second-level fire, and the target number of fire-fighting agent containers corresponding to the second-level fire is 4. If the environmental temperature of the target energy storage unit is within 50°C-100°C of the temperature safety threshold, the fire situation is a third-level fire, and the target number of fire-fighting agent containers corresponding to the third-level fire is 5.

[0096] In addition, the fire situation of the target energy storage unit can also be related to the volume of the target energy storage unit and the type of the target energy storage unit. For example, a larger volume energy storage unit has a larger fire in the event of a fire, so the number of fire extinguishing agent containers required for a larger volume energy storage unit is more than that required for a smaller volume energy storage unit. For another example, the electrolyte or electrode material used in the energy storage unit has a longer duration in the event of a fire, so the number of fire extinguishing agent containers corresponding to such energy storage units is configured to be more.

[0097] In addition, the way in which the present scheme determines the target number of fire extinguishing agent containers can be: selecting the fire extinguishing agent containers corresponding to the target number of energy storage units from near to far according to the distance from the target energy storage unit.
