[0002] With the rapid development of energy storage technology, energy storage systems have been widely used in many industries. However, since the energy storage devices in the energy storage system will generate heat after long-term use, and multiple energy storage devices are stacked densely, the heat cannot be fully dissipated, and there is a risk of fire caused by heat accumulation.

[0003] Existing energy storage fire fighting systems are all independently configured, that is, each energy storage unit is equipped with a fire fighting system. Once an abnormality of the energy storage unit is detected, the corresponding fire fighting system is immediately activated to extinguish the fire. However, each energy storage unit is equipped with a fire fighting system, which has the problem of high cost. Summary of the invention

[0004] In view of the above problems, the present application provides a fire protection system and its energy storage power station, fire protection control method and electronic equipment, which can solve the high cost problem caused by each energy storage unit of the current energy storage system being equipped with a fire protection system separately.

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

[0006] In the technical solution of the embodiment of the present application, the solution designs a fire-fighting pipe network, connects a main pipe and an energy storage unit through each branch pipe of the fire-fighting pipe network, and arranges a fire-fighting agent container for storing fire-fighting agent on the branch pipe, so that after the acquisition control unit determines that there is a target energy storage unit that needs to be extinguished according to the environmental characteristic information of the energy storage unit, the fire-fighting agent in the fire-fighting agent container in the fire-fighting pipe network is controlled to spray out, and the target energy storage unit that needs to be extinguished is extinguished, thereby realizing fire-fighting management and control of multiple energy storage units through a simple fire-fighting pipe network, thereby solving the high cost problem caused by designing a fire-fighting system separately for each energy storage unit in the existing energy storage system, and reducing the fire-fighting cost of the energy storage system.

[0007] In some embodiments, the acquisition control unit is specifically used to control the fire-fighting agent in the fire-fighting agent container of the branch pipeline corresponding to the target energy storage unit to spray into the target energy storage unit to extinguish the target energy storage unit. In this embodiment, the acquisition control unit controls the fire-fighting agent in the fire-fighting agent container of the branch pipeline corresponding to the target energy storage unit to extinguish the fire, thereby quickly responding to firefighting needs.

[0008] In some embodiments, a first valve is provided between the fire-fighting agent container of each branch pipeline and the corresponding energy storage unit, and the acquisition control unit communicates with each first valve; the acquisition control unit is specifically used to control the first valve of the branch pipeline corresponding to the target energy storage unit to open, so as to control the fire-fighting agent in the fire-fighting agent container of the branch pipeline corresponding to the target energy storage unit to be sprayed into the target energy storage unit. This embodiment realizes the fire-fighting of the target energy storage unit through the simplified opening and closing control of the first valve, simplifies the fire-fighting control process, and thus realizes a rapid fire-fighting response.

[0009] In some embodiments, the acquisition control unit is specifically used 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 extinguish the target energy storage unit. In addition to controlling the fire-fighting agent in the fire-fighting agent container corresponding to the target energy storage unit, this embodiment can also call the fire-fighting agent in the fire-fighting agent container corresponding to other energy storage units, so that the fire-fighting system designed by this scheme has the fire-fighting ability to deal with fires that cannot be extinguished by a single fire-fighting pipeline, thereby improving the reliability and processing capability of the fire-fighting system.

[0010] In some embodiments, the acquisition control unit is specifically used to: control the fire-fighting agent in the fire-fighting agent container of the branch pipeline corresponding to the target energy storage unit to be sprayed into the target energy storage unit, and start the 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 that the fire-fighting agent in the fire-fighting agent container corresponding to the target energy storage unit can continue to spray; if it is determined that the real-time environmental characteristic information of the target energy storage unit does not meet the fire-fighting cut-off condition when the fire-fighting time is reached in the first timing, then control the fire-fighting agent in the fire-fighting agent container of the branch pipeline corresponding to other energy storage units other than the target energy storage unit to be sprayed into the target energy storage unit. This embodiment determines whether the fire-fighting agent in the fire-fighting agent container corresponding to the target energy storage unit is about to be exhausted by timing, and thus calls the fire-fighting agent in the fire-fighting agent container of other energy storage units according to the exhaustion situation, thereby avoiding the problem of fire growth caused by the delay of the fire-fighting agent and improving the timeliness of fire fighting.

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

[0012] In some embodiments, the acquisition control unit is further specifically used to: after controlling the fire-fighting agent container corresponding to the nearest energy storage unit of the target energy storage unit to extinguish the target energy storage unit, start the second timing; if the real-time environmental characteristic information of the target energy storage unit meets the fire-fighting cut-off condition before the second timing reaches the fire-fighting time, then stop the fire-fighting; if the real-time environmental characteristic information of the target energy storage unit does not meet the fire-fighting cut-off condition after the second timing reaches the fire-fighting time, then control the fire-fighting agent in the fire-fighting agent container corresponding to the branch pipeline of the energy storage unit of the second nearest neighbor of the target energy storage unit to spray 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 and second nearest neighbor of the target energy storage unit, thereby improving the response speed of fire-fighting.

DETAILED DESCRIPTION

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

[0048] With the rapid development of energy storage technology, energy storage systems have been widely used in many industries. However, since the energy storage devices in the energy storage system will generate heat after long-term use, and multiple energy storage devices are stacked densely, the heat cannot be fully dissipated, and there is a risk of fire caused by heat accumulation. Therefore, energy storage systems are often equipped with fire protection systems to reduce fire risks.

[0049] Existing energy storage fire fighting systems are all independently configured, that is, each energy storage unit is equipped with a fire fighting system. Once an abnormality of the energy storage unit is detected, the corresponding fire fighting system is immediately activated to extinguish the fire. However, each energy storage unit is equipped with a fire fighting system, which has the problem of high cost.

[0050] The present application designs a fire fighting system and its energy storage power station, fire fighting control method and electronic equipment, which connect the fire fighting agents of various energy storage units through a fire fighting pipe network, so that when any one or more energy storage units have a fire risk, the fire fighting agent can be transported to the energy storage unit with a fire risk by using the fire fighting pipe network, thereby simplifying the fire fighting system of the energy storage system and achieving a more ideal fire fighting effect. In addition, when the fire fighting agent in a certain fire fighting agent container is insufficient, the fire fighting agent in the fire fighting agent container corresponding to other energy storage units can be called to participate in the fire fighting, thereby improving the fire fighting capability.

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

[0052] As a possible implementation, the fire-fighting agent container 230 for storing the fire-fighting agent provided on the N branch pipes 220 may be as follows: Figure 1 Each of the N branch pipes 220 shown in the figure is provided with a fire-fighting agent container 230. As another possible embodiment, the fire-fighting agent container 230 for storing fire-fighting agent provided on the N branch pipes 220 may also be a human Figure 2 Fire-fighting agent containers 230 are provided on some of the N branch pipes 220 shown.

[0053] In the fire protection system 1 designed as above, the acquisition control unit 10 can collect environmental characteristic information of each energy storage unit A in the energy storage system 2, wherein the environmental characteristic information may include one or more of the temperature information, smoke information and combustible gas information of the energy storage unit environment, and then the acquisition control unit 10 can determine whether there is a target energy storage unit that needs to be extinguished among the multiple 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 extinguished, the acquisition control unit 10 controls the extinguishing agent in the extinguishing agent container 230 of the fire protection pipe network 20 to spray out the extinguishing agent to extinguish the target energy storage unit. Among them, the present scheme can set safety thresholds in advance, such as temperature safety thresholds, smoke / combustible gas concentration safety thresholds, etc. The acquisition control unit can compare the environmental characteristic information of each energy storage unit obtained with the corresponding safety threshold. If the environmental characteristic information exceeds the safety threshold, the energy storage unit whose environmental characteristic information exceeds the safety threshold is determined to be the target energy storage unit that needs to be extinguished. For example, this solution can compare the ambient temperature of each energy storage unit with the corresponding temperature safety threshold. If the ambient temperature exceeds the corresponding temperature safety threshold, the energy storage unit whose ambient temperature exceeds the temperature safety threshold is determined to be a target energy storage unit that needs fire fighting. Specifically, this solution can set a unique identifier for each energy storage unit in advance. For example, the N energy storage units can be A1, A2, A3...AN-1 and AN respectively. When collecting environmental characteristic information, the control unit can also obtain the unique identifier of the energy storage unit corresponding to 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, and then determine that there is a target energy storage unit that needs fire fighting.

[0054] Among them, when a fire-fighting agent container 230 is provided on each of the N branch pipes 220, as a possible implementation manner, the acquisition control unit 10 controls the spraying of the fire-fighting agent in the fire-fighting agent container 230 of the fire-fighting pipe network 20 by controlling the spraying of the fire-fighting agent in the fire-fighting agent container 230 on the branch pipe 220 corresponding to the target energy storage unit; as another possible implementation manner, the acquisition control unit 10 can control the fire-fighting agent container 230 corresponding to other energy storage units as a fire-fighting agent supplement in addition to controlling the spraying of the fire-fighting agent in the fire-fighting agent container 230 on the branch pipe 220 corresponding to the target energy storage unit.

[0055] The fire protection system 1 designed above, this scheme designs a fire protection pipe network, connects the main pipe and an energy storage unit through each branch pipe of the fire protection pipe network, and arranges a fire protection agent container for storing fire protection agent on the branch pipe, so that after the acquisition control unit determines that there is a target energy storage unit that needs to be extinguished according to the environmental characteristic information of the energy storage unit, the fire protection agent in the fire protection agent container in the fire protection pipe network is controlled to spray out, and the target energy storage unit that needs to be extinguished is extinguished, thereby realizing the fire protection management and control of multiple energy storage units through a simple fire protection pipe network, thereby solving the high cost problem caused by designing a fire protection system for each energy storage unit in the existing energy storage system, and reducing the fire protection cost of the energy storage system.

[0056] In an optional implementation of this embodiment, it is described above that the acquisition control unit 10 can control the fire-fighting agent in the fire-fighting agent container 230 on the branch pipeline 220 corresponding to the target energy storage unit to spray out. As a possible implementation, the fire-fighting agent spraying in the fire-fighting agent container 230 can be controlled by a valve. Specifically, Figure 2 As shown, a first valve 240 is provided between the fire-fighting agent container 230 of each branch pipe 220 in the fire-fighting system and the corresponding energy storage unit A, and 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 open, thereby controlling the fire-fighting agent container 230 of the branch pipe 220 corresponding to the target energy storage unit to be connected with the pipe of the target energy storage unit, so that the fire-fighting agent is sprayed into the target energy storage unit, thereby realizing the fire-fighting of the target energy storage unit.

[0057] Among them, this scheme can establish a unique identifier for each first valve in advance, and then bind the unique identifier of each energy storage unit with the unique identifier of the first valve on the branch pipeline corresponding to the energy storage unit. For example, the target first valve corresponding to the first energy storage unit A1 may be 240A1. This scheme binds A1 to 240A1, so that when the first energy storage unit A1 is determined to be the target energy storage unit, the corresponding target first valve 240A1 can be controlled.

[0058] In the above implementation mode, the present scheme controls the first valve on the branch pipeline corresponding to the target energy storage unit through the acquisition control unit 10, so that the fire-fighting agent container 230 of the branch pipeline 220 corresponding to the target energy storage unit is connected to the pipeline of the target energy storage unit, thereby simplifying the fire control of the target energy storage unit.

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

[0060] As a specific implementation, the acquisition control unit 10 may first control the fire-fighting agent in the fire-fighting agent container 230 of the branch pipe 220 corresponding to the target energy storage unit to be sprayed into the target energy storage unit for fire-fighting, and then the acquisition control unit 10 starts the first timing. If it is determined that the real-time environmental characteristic information of the target energy storage unit does not meet the fire-fighting cut-off condition when the first timing reaches the fire-fighting time, it means that the fire-fighting agent stored in the fire-fighting agent container 230 on the branch pipe 220 corresponding to the target energy storage unit is almost finished, but the fire in the target energy storage unit has not been controlled. On this basis, the acquisition control unit controls the fire-fighting agent in the fire-fighting agent containers of the branch pipes corresponding to other energy storage units other than 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 fighting time described above 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. Specifically, the fire fighting 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 fighting agent capacity of the target energy storage unit and the fire fighting agent spraying speed. The preset delay time is set according to an empirical value, and can be specifically determined according to the time when the fire fighting agent in the fire fighting agent container farthest from the target energy storage unit reaches the position of the target energy storage unit.

[0062] In the above implementation mode, after controlling the fire-fighting agent in the fire-fighting agent container 230 of the branch pipe 220 corresponding to the target energy storage unit to be sprayed into the target energy storage unit for fire-fighting, the first timing starts. When the first timing reaches the fire-fighting time, the real-time environmental characteristic information of the target energy storage unit does not meet the fire-fighting cut-off condition, that is, the fire has not been controlled, the acquisition control unit controls the fire-fighting agent in the fire-fighting agent containers of the branch pipes corresponding to other energy storage units other than the target energy storage unit to be sprayed into the target energy storage unit, thereby further extinguishing the fire and improving the reliability of fire-fighting of the energy storage system.

[0063] In an optional implementation of this embodiment, it is described above that the energy storage system includes N energy storage units. In this regard, this solution can select the fire-fighting agent containers of other energy storage units other than the target energy storage unit in the following manner. Specifically, the acquisition control unit can first control the fire-fighting agent container corresponding to the energy storage unit closest to the target energy storage unit to extinguish the target energy storage unit, and then start the second timing. If the real-time environmental feature information of the target energy storage unit meets the fire-fighting cut-off condition before the second timing reaches the fire-fighting time, it means that the fire in the target energy storage unit has been controlled. On this basis, the acquisition control unit 10 controls the fire-fighting to stop.

[0064] If the collection control unit 10 determines that the real-time environmental characteristic information of the target energy storage unit does not meet the fire cut-off condition when the second timing reaches the fire-fighting time, the collection control unit 10 controls the fire-fighting agent in the fire-fighting agent container of the branch pipeline corresponding to the energy storage unit of the next nearest neighbor of the target energy storage unit to be sprayed into the target energy storage unit, thereby achieving further fire-fighting.

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

[0066] As a specific implementation method, Figure 3 As shown, the fire-fighting agent container 230 of each branch pipeline 220 and the corresponding energy storage unit A in the fire-fighting system 1 are not only provided with a first valve 240, but also a second valve 250 is provided between the fire-fighting agent container 230 of each branch pipeline 220 and the main pipeline 210. On this basis, the acquisition control unit can control the second valve 250 corresponding to the target energy storage unit to open, and control the second valve 250 corresponding to the energy storage unit adjacent to the target energy storage unit to open, so as to control the fire-fighting agent container 230 corresponding to the energy storage unit adjacent to the target energy storage unit to enter the branch pipeline 220 corresponding to the target energy storage unit, so as to extinguish the target energy storage unit.

[0067] Among them, this 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 identifier of the first valve and second valve on the branch pipeline 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 corresponding target second valve can be 250A1. This solution binds A1 with 240A1 and 250A1, so that when the first energy storage unit A1 is determined to be the target energy storage unit, the corresponding target first valve 240A1 and the target second valve 250A1 can be controlled.

[0068] For example, 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, and 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. The acquisition control unit 10 also starts the first timing. During the first timing, the acquisition control unit 10 obtains the real-time environmental characteristic information of the first energy storage unit A1, and determines whether the real-time environmental characteristic information meets the fire-fighting cut-off condition. If the real-time environmental characteristic information does not meet the fire-fighting cut-off 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, thereby controlling 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 and the main pipe 2 corresponding to the second energy storage unit A2. 10 and the branch pipeline corresponding to the first energy storage unit A1, and then spray 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 obtains the real-time environmental feature information of the first energy storage unit A1, and determines whether the real-time environmental feature information meets the fire fighting cut-off condition. If the real-time environmental feature information meets the fire fighting cut-off condition before the second timing reaches the fire fighting time, all valves are controlled to be closed, and then the fire fighting is stopped; if the real-time environmental feature information still does not meet the fire fighting cut-off 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 pipeline corresponding to the third energy storage unit A3, the main pipeline 210 and the branch pipeline corresponding to the first energy storage unit A1, and then spray into the first energy storage unit A1 for fire fighting.

[0069] It should be noted here that since each branch pipe 220 in the fire protection system is provided with a second valve 250, when the collection control unit 10 calls the fire protection agent corresponding to other energy storage units, it only needs to open the second valve 250 on the branch pipe of the target energy storage unit and the called energy storage unit.

[0070] In the above implementation mode, in addition to using the fire-fighting agent in the fire-fighting agent container corresponding to the target energy storage unit itself, this scheme can also call on the fire-fighting agent in the fire-fighting agent container corresponding to other energy storage units, so as to safely extinguish a larger fire and improve the reliability of firefighting.

[0071] In an optional implementation of this embodiment, if Figure 5As shown, a booster pump 30 and a pressure sensor 40 may also be provided on the main pipeline 210 of the fire protection system designed in this scheme, 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 when the pressure value of the main pipeline 210 is lower than the preset pressure value.

[0072] In the above-mentioned implementation mode, this scheme monitors the pressure value of the main pipeline 210 through the pressure sensor 40. When the pressure value of the main pipeline 210 is lower than the preset pressure value, the booster pump 30 is controlled to start, so as to increase the pressure of the main pipeline 210 through the booster pump 30, thereby ensuring the spraying speed of the fire-fighting agent and providing the necessary guiding force for the spraying of the fire-fighting agent, so that the fire-fighting agent in the fire-fighting agent container 230 can enter the fire-fighting pipeline network as much as possible, avoiding the problem of insufficient spraying force or excessive residue of the fire-fighting agent caused by too low pressure.

[0073] In an optional implementation of this embodiment, if Figure 6 As shown, the fire protection system designed in this scheme includes a storage device 50, both ends of which are connected to the main pipeline 210 through a first storage branch pipeline 510 and a second storage branch pipeline 520 respectively, a first boosting pump 60 and a first pressure sensor 70 are arranged on the first storage branch pipeline 510, a second boosting pump 80 and a second pressure sensor 90 are arranged on the second storage branch pipeline 520, and the acquisition control unit 10 is electrically connected to the first boosting pump 60, the second boosting pump 80, the first pressure sensor 70 and the second pressure sensor 90 respectively.

[0074] The acquisition control unit 10 is also used to control the first booster pump 60 and the second booster pump 80 to start when the second valve 250 corresponding to the target energy storage unit and the second valve 250 corresponding to the energy storage unit adjacent to the target energy storage unit are opened, so as to timely deliver 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, thereby improving the timeliness and reliability of fire-fighting.

[0075] In an optional implementation of this embodiment, if Figure 7 As shown, the collection control unit 10 may include a collection unit 100 and a control unit 101, the collection unit 100 and the control unit 101 are electrically connected, the collection unit 100 may include multiple temperature sensors and / or smoke sensors and / or combustible gas sensors, each energy storage unit A is provided with a collection unit 100, the collection unit 100 is used to collect environmental characteristic information of the energy storage unit A and transmit it to the control unit 101, and the control unit 101 executes the fire control process.

[0076] In an optional implementation of this embodiment, during the fire fighting process of the target energy storage unit, the acquisition control unit 10 obtains the real-time environmental characteristic information of the target energy storage unit, determines whether the real-time environmental characteristic information of the target energy storage unit meets the fire fighting cut-off condition, and stops the fire fighting if it is determined that the real-time environmental characteristic information of the target energy storage unit meets the fire fighting cut-off condition. The fire fighting cut-off condition may include that various environmental characteristics of the target energy storage unit are reduced to a safe value, for example, the fire fighting cut-off condition may be that the ambient temperature of the target energy storage unit is reduced to below a preset safe temperature, or the ambient smoke / combustible gas concentration of the target energy storage unit is reduced to below a preset concentration value, etc.

[0077] The present application also provides an energy storage power station, such as Figure 8 As shown, the energy storage power station includes an energy storage system 2 and a fire fighting system 1 of any optional embodiment described above.

[0078] In the energy storage power station designed as above, this scheme designs a fire-fighting pipe network, connects the main pipe and an energy storage unit through each branch pipe of the fire-fighting pipe network, and arranges a fire-fighting agent container for storing the fire-fighting agent on the branch pipe. After the acquisition control unit determines that there is a target energy storage unit that needs to be extinguished according to the environmental characteristic information of the energy storage unit, the fire-fighting agent in the fire-fighting agent container in the fire-fighting pipe network is controlled to spray out, and the target energy storage unit that needs to be extinguished is extinguished, thereby realizing the fire-fighting management and control of multiple energy storage units through a simple fire-fighting pipe network, thereby solving the high cost problem caused by designing a fire-fighting system for each energy storage unit in the existing energy storage system, and reducing the fire-fighting cost of the energy storage system.

[0079] The present application also provides a fire control method, which is executed by the acquisition control unit in the fire system described above. Fig. 9 As shown, the fire control method can be implemented in the following ways, including:

[0080] Step S900: Collecting 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 fire protection among the multiple energy storage units according to the environmental characteristic information of each energy storage unit.

[0082] Step S920: When it is determined that there is a target energy storage unit that needs fire fighting, the fire fighting agent in the fire fighting agent container of the fire fighting pipe network is controlled to spray out to fight the target energy storage unit.

[0083] In the above-mentioned embodiments, the energy storage system and the fire protection system can be consistent with the energy storage system and the fire protection system described above, which will not be described in detail here; in addition, the energy storage system and the fire protection system can also adopt other energy storage systems and fire protection systems with corresponding functional characteristics in the field. Among them, the environmental characteristic information is information related to the environment in which the energy storage unit is located, for example, the temperature of the environment in which the energy storage unit is located, the smoke concentration of the environment in which the energy storage unit is located, and the combustible gas concentration of the environment in which the energy storage unit is located, etc. The environmental characteristics referred to in the above text include any one or any multiple of the examples listed. Among them, the environmental characteristic information of each energy storage unit can be obtained by collecting relevant sensors set in the energy storage unit. For example, by setting a temperature sensor in the energy storage unit, the temperature of the environment in which the energy storage unit is located is collected; by setting a smoke sensor in the energy storage unit, the smoke concentration of the environment in which the energy storage unit is located is collected; by setting a combustible gas sensor in the energy storage unit, the combustible gas concentration of the environment in which the energy storage unit is located is collected.

[0084] When the environmental characteristic information of each energy storage unit is obtained in the above manner, the acquisition control unit can determine whether there is a target energy storage unit that needs fire protection among the multiple energy storage units based on the environmental characteristic information of each energy storage unit. Specifically, this solution can set safety thresholds in advance, such as temperature safety thresholds, smoke / combustible gas concentration safety thresholds, etc. The acquisition control unit can compare the environmental characteristic information of each energy storage unit obtained with the corresponding safety threshold. If the environmental characteristic information exceeds the safety threshold, the energy storage unit whose environmental characteristic information exceeds the safety threshold is determined to be a target energy storage unit that needs fire protection. For example, this solution can compare the ambient temperature of each energy storage unit with the corresponding temperature safety threshold. If the ambient temperature exceeds the corresponding temperature safety threshold, the energy storage unit whose ambient temperature exceeds the temperature safety threshold is determined to be a target energy storage unit that needs fire protection.

[0085] In the case where it is determined that there is a target energy storage unit that needs to be extinguished, this solution can control the fire-fighting agent in the fire-fighting agent container of the fire-fighting pipeline network to spray out, thereby extinguishing the target energy storage unit.

[0086] The fire control method designed above, this scheme designs a fire-fighting pipe network, connects the main pipe and an energy storage unit through each branch pipe of the fire-fighting pipe network, and arranges a fire-fighting agent container for storing fire-fighting agent on the branch pipe, so as to determine the existence of a target energy storage unit that needs to be extinguished according to the environmental characteristic information of the energy storage unit, and then controls the fire-fighting agent in the fire-fighting agent container in the fire-fighting pipe network to spray out, and extinguishes the target energy storage unit that needs to be extinguished, thereby realizing fire-fighting management and control of multiple energy storage units through a simple fire-fighting pipe network, thereby solving the high cost problem caused by designing a fire-fighting system separately for each energy storage unit in the existing energy storage system, and reducing the fire-fighting cost of the energy storage system.

[0087] As a possible implementation, for step S920, this solution can specifically control the fire-fighting agent in the fire-fighting agent container of the branch pipeline corresponding to the target energy storage unit to spray into the target energy storage unit to extinguish the target energy storage unit. Figure 3 The implementation method introduced is the same and will not be repeated here.

[0088] As another possible implementation, for step S920, when the fire in the target energy storage unit is large, the fire-fighting agent in the fire-fighting container corresponding to the target energy storage unit cannot control the fire. In this regard, the present solution can also control the fire-fighting agent container of the branch pipeline corresponding to the target energy storage unit and the fire-fighting agent containers of other energy storage units other than the target energy storage unit to spray into the target energy storage unit to extinguish the target energy storage unit. Thus, when the fire in the target storage unit is large, the fire-fighting agent can be replenished in multiple locations in time through the fire-fighting pipeline network, thereby improving the reliability of fire-fighting.

[0089] Furthermore, the present solution may first control the fire-fighting agent in the fire-fighting 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. During the timing process, the acquisition control unit obtains the real-time environmental characteristic information of the target energy storage unit, and determines whether the real-time environmental characteristic information satisfies the fire-fighting cut-off condition. If the real-time environmental characteristic information of the target energy storage unit satisfies the fire-fighting cut-off condition before the fire-fighting time is reached in the first timing, it means that the fire in the target energy storage unit has been controlled, and the fire-fighting is stopped.

[0090] If the real-time environmental characteristic information of the target energy storage unit still does not meet the fire cut-off condition when the first timing reaches the fire-fighting time, the fire-fighting agent in the fire-fighting agent container of the corresponding branch pipeline of other energy storage units other than the target energy storage unit is controlled to be sprayed into the target energy storage unit, so as to carry out supplementary fire fighting.

[0091] Specifically, other energy storage units other than the target energy storage unit may include energy storage units adjacent to the target energy storage unit. For example, the energy storage unit that is the closest neighbor to the target energy storage unit and the energy storage unit that is the second closest neighbor to the target energy storage unit. The nearest neighbor energy storage unit refers to the energy storage unit that is closest to the target energy storage unit, and the second closest neighbor energy storage unit refers to the energy storage unit that is second only to the closest distance to the target energy storage unit.

[0092] On this basis, this solution controls the fire-fighting agent in the fire-fighting agent container of the branch pipeline corresponding to other energy storage units other than the target energy storage unit to be sprayed into the target energy storage unit. It can first control the fire-fighting agent container corresponding to the nearest energy storage unit of the target energy storage unit to extinguish the target energy storage unit, and then start the second timing. During the timing process, the acquisition control unit obtains the real-time environmental characteristic information of the target energy storage unit, and determines whether the real-time environmental characteristic information meets the fire-fighting cut-off condition. If the real-time environmental characteristic information of the target energy storage unit still does not meet the fire-fighting cut-off condition when the second timing reaches the fire-fighting time, the fire-fighting agent in the fire-fighting agent container of the branch pipeline corresponding to the next nearest energy storage unit is controlled to be sprayed into the target energy storage unit. Among them, the specific implementation method has been introduced in the fire-fighting system above, and will not be repeated here.

[0093] Among them, the fire cutoff condition described above may be that the various environmental characteristics of the target energy storage unit are reduced to safe values. For example, the fire cutoff condition may be that the ambient temperature of the target energy storage unit is reduced below a preset safety temperature, or the ambient smoke / combustible gas concentration of the target energy storage unit is reduced below a preset concentration value, etc.

[0094] In an optional implementation manner of this embodiment, in addition to controlling the firefighting of the energy storage system in the above-mentioned manner, this scheme can also first determine the target number of fire-fighting agent containers required corresponding 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 be sprayed into the target energy storage unit for firefighting; during the firefighting process, this scheme can continuously monitor the real-time environmental characteristic information of the target energy storage unit, and 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 does not meet the fire-fighting cut-off condition, the fire-fighting agent containers of other energy storage units are called in sequence for firefighting as described above until the real-time environmental characteristics meet the fire-fighting cut-off condition.

[0095] Among them, the fire situation of the target energy storage unit can be determined by the environmental characteristic information of the target energy storage unit. For example, this solution can determine the fire situation of the target energy storage unit according to the ambient temperature of the target energy storage unit, or it can determine the fire situation of the target energy storage unit according to the smoke concentration or combustible gas concentration of the target energy storage unit. Specifically, taking temperature as an example, if the ambient temperature of the target energy storage unit exceeds the temperature safety threshold by less than 20°C, it is a first-level fire, and the target number of fire-fighting agent containers corresponding to the first-level fire is 3; if it exceeds the temperature safety threshold by 20°C-50°C, it is a second-level fire, and the target number of fire-fighting agents for the second-level fire is 4; if it exceeds the safety threshold by 50°C-100°C, it is a third-level fire, and the target number of fire-fighting agents for the third-level fire is 5.

[0096] In addition, the fire intensity of the target energy storage may 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 energy storage unit will have a greater fire intensity when on fire, so a larger energy storage unit requires more fire-fighting agent containers than a smaller energy storage unit. For another example, if the electrolyte or electrode material used in the energy storage unit lasts longer when on fire, then more fire-fighting agent containers are configured for such energy storage units.

[0097] In addition, the method of determining the target number of fire-fighting agent containers in this solution may be: selecting fire-fighting agent containers corresponding to the target number of energy storage units in a manner from near to far from the target energy storage unit.
