Description

Technical Field

[0001] The present application relates to the field of fire protection technology, and in particular to an energy storage device, a fire protection control method and a storage medium. Background Art

[0002] As new energy storage equipment is widely used, fire accidents in energy storage equipment have attracted close attention. When the batteries in the energy storage equipment are overheated, overcharged, over-discharged, impacted, squeezed, or short-circuited, chemical reactions occur between the various materials inside the battery, causing thermal runaway of the battery, and ultimately inducing safety accidents such as fire or explosion of the energy storage equipment.

[0003] In the related art, most fire control schemes for energy storage equipment only use a gas fire extinguishing system to suppress battery fires. The gas fire extinguishing suppression device of this type of scheme usually needs to be configured in a container. The storage capacity of the gas suppression device is limited by the container space, and the complete suppression capability is poor. The battery is prone to the risk of thermal runaway again, and the battery thermal runaway suppression effect is not ideal. Summary of the invention

[0074] In order to make the features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0075] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0076] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0077] In the related art, most fire control schemes for energy storage equipment only use a gas fire extinguishing system to suppress battery fires. The gas fire extinguishing suppression device of this type of scheme usually needs to be configured in a container. The storage capacity of the gas suppression device is limited by the container space, and the complete suppression capability is poor. The battery is prone to the risk of thermal runaway again, and the battery thermal runaway suppression effect is not ideal.

[0078] To solve the problems in the related art, the embodiments of the present application provide an energy storage device, a fire control method and a storage medium, which are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the priority order of the embodiments.

[0079] See also Figure 1 , Figure 1 1 is a schematic diagram of the first structure of the energy storage device provided in the embodiment of the present application. The energy storage device 10 may include an energy storage compartment 11, a first fire fighting system 12, a second fire fighting system 13, a processor 14, and a transmission pipeline 15. The first fire fighting system 12 and the second fire fighting system 13 are connected to the energy storage compartment 11 through the transmission pipeline 15, respectively.

[0080] The processor 14 is electrically connected to the first fire fighting system 12 and the second fire fighting system 13 respectively. The processor 14 can be used to: if a fire is detected in the target area of ​​the energy storage cabin 11, control the first fire fighting system 12 or the second fire fighting system 13 to transport the target inhibitor used for fire extinguishing to the target area through the delivery pipeline 15, so as to extinguish the fire in the target area through the target inhibitor, thereby transporting the target inhibitor in the first fire fighting system 12 or the second fire fighting system 13 to the target area of ​​the energy storage cabin 11 through the same delivery pipeline 15 for fire extinguishing. While improving the fire extinguishing effect, it can also achieve precise fire extinguishing in the target area of ​​the energy storage cabin 11, thereby protecting the area where no fire has occurred in the energy storage device 10.

[0081] For further details of the energy storage device 10, please refer to Figure 2 , Figure 21 is a second structural diagram of the energy storage device provided in the embodiment of the present application. The energy storage device 10 may be a large energy storage device, such as an energy storage power station.

[0082] The energy storage cabin 11 may include an energy storage unit, a thermal management system, an electrical system, a structure and a shell, a ventilation and air quality system, maintenance and repair facilities, environmental adaptability equipment, and a display and warning system, etc.

[0083] The first fire fighting system 12 and the second fire fighting system 13 can both deliver the target suppressant for extinguishing the fire into the target area through the delivery pipeline 15, so as to extinguish the fire in the target area through the target suppressant. The target suppressants delivered by the first fire fighting system 12 and the second fire fighting system 13 can be different target suppressants, and specifically, the target suppressants can include fire extinguishing agents and external water sources.

[0084] The first fire protection system 12 may include a fire extinguishing device 121, wherein the fire extinguishing device 121 stores a fire extinguishing agent, which may be a perfluorohexanone fire extinguishing agent. The perfluorohexanone fire extinguishing agent is a clean fire extinguishing agent because it does not leave any residual substances during the fire extinguishing process and does not cause corrosion and pollution to the equipment. The perfluorohexanone fire extinguishing agent has good electrical insulation properties and can be used without cutting off the power supply. It also has a high fire extinguishing efficiency and can effectively extinguish fires such as liquid fires, gas fires, and electrical fires. Of course, the fire extinguishing agent in the fire extinguishing device 121 may also be other types of fire extinguishing agents such as aerosols, inert gases, carbon dioxide, dry powder, heptafluoropropane, and the type of fire extinguishing agent is not specifically limited here.

[0085] The first end of the delivery pipeline 15 is connected to the fire extinguishing device 121, and the second end of the delivery pipeline 15 extends into the energy storage cabin 11. Therefore, the fire extinguishing agent in the fire extinguishing device 121 can be delivered to the energy storage cabin 11 through the delivery pipeline 15, so that when a fire occurs in the energy storage cabin 11, the fire extinguishing agent is used to extinguish the fire in the energy storage cabin 11. Specifically, if a fire occurs in the target area of ​​the energy storage cabin 11, the fire extinguishing agent is used to extinguish the fire in the target area of ​​the energy storage cabin 11, thereby achieving precise fire extinguishing of the target area, while other areas of the energy storage cabin 11 other than the target area where no fire occurs are not extinguished, so that other areas will not be affected by the fire extinguishing agent and protection of other areas is achieved.

[0086] It should be noted that since the fire extinguishing device 121 is arranged in the first fire protection system 12, and the first fire protection system 12 is arranged in the energy storage device 10, in order to ensure the rationality of the assembly of various components in the energy storage device 10, the space occupied by the fire extinguishing device 121 will not be too large. Therefore, the volume of the fire extinguishing agent stored in the fire extinguishing device 121 is limited. Under normal circumstances, the volume of the fire extinguishing agent stored in the fire extinguishing device 121 can support one to two fire extinguishing treatments on the energy storage cabin 11.

[0087] In order to ensure that the energy storage device 10 can suppress multiple fires, in addition to realizing fire protection of the energy storage cabin 11 through the first fire protection system 12, this embodiment also provides a second fire protection system 13, which includes a driving device 131, a first end of which is connected to the first end of the delivery pipeline 15, and a second end of which is connected to an external water source. The driving device 131 can be a device driven by a motor or other power source, such as a water pump.

[0088] Specifically, when a fire occurs in the target area of ​​the energy storage cabin 11, the driving valve of the driving device 131 is opened to introduce the external water source into the target area of ​​the energy storage cabin 11 through the delivery pipeline 15, so that the target area of ​​the energy storage cabin 11 can be extinguished by the external water source. Optionally, the external water source can be fire water, for example, the second end of the driving device 131 is connected to a fire water tank through a pipeline, and when a fire occurs in the target area of ​​the energy storage cabin 11, the driving device 131 introduces the external water source into the target area for fire extinguishing.

[0089] Among them, after a fire occurs in the target area of ​​the energy storage cabin 11, the energy storage cabin 11 can be extinguished by a fire extinguishing agent or an external water source. In some embodiments, after a fire occurs in the target area of ​​the energy storage cabin 11, a fire extinguishing agent can be used to extinguish the fire first, and then an external water source can be used to extinguish the fire after the fire extinguishing agent is exhausted. The specific fire extinguishing strategy is not specifically limited here and can be set accordingly according to actual conditions. Among them, the fire extinguishing agent or the external water source are both transported to the target area through a delivery pipeline.

[0090] In some embodiments, the second end of the delivery pipeline 15 extends into the energy storage cabin 11. Specifically, a plurality of nozzles are provided on the top of the energy storage cabin 11, and the plurality of nozzles can be respectively provided at the four corner areas of the top of the energy storage cabin 11. The plurality of nozzles are respectively connected to the second end of the delivery pipeline 15, so that the fire extinguishing agent in the fire extinguishing device 121 and the external water source introduced by the driving device 131 enter the energy storage cabin 11 and extinguish the fire in the energy storage cabin 11 by spraying. The number of nozzles can be set accordingly according to the volume of the energy storage cabin 11, and is not specifically limited here.

[0091] The energy storage device 10 may further include a processor 14, which is electrically connected to the energy storage cabin 11, the first fire-fighting system 12 and the second fire-fighting system 13, respectively. The processor 14 may be used to execute: if a fire is detected in the target area of ​​the energy storage cabin 11, the fire-fighting device 121 of the first fire-fighting system 12 is controlled to transport the fire-extinguishing agent to the target area of ​​the energy storage cabin 11 via the delivery pipeline 15, so as to extinguish the fire in the target area of ​​the energy storage cabin 11 with the fire-extinguishing agent; or if a fire is detected in the target area of ​​the energy storage cabin 11, the driving device 131 of the second fire-fighting system 13 is controlled to transport the external water source to the target area of ​​the energy storage cabin 11 via the delivery pipeline 15, so as to extinguish the fire in the target area of ​​the energy storage cabin 11 with the external water source.

[0092] It should be noted that the target area of ​​the energy storage cabin 11 can be any area in the energy storage cabin, and the second end of the delivery pipeline 15 extends into the energy storage cabin 11. Specifically, the delivery pipeline 15 can be connected to any area in the energy storage cabin 11, and the delivery pipeline 15 is provided with a partition control valve in each area of ​​the energy storage cabin 11. In some embodiments, when a fire occurs in the target area of ​​the energy storage cabin 11, the delivery pipeline 15 controls the target partition control valve connected to the target area to open, while other partition control valves remain closed, so that the fire extinguishing agent or external water source is delivered to the target area through the delivery pipeline 15 for fire extinguishing treatment, and other areas where no fire occurs will not have fire extinguishing agent or external water source entering because the partition control valves remain closed, and other areas are kept working normally, thereby achieving precise fire extinguishing of the target area, and protecting the area where no fire occurs, thereby improving the fire extinguishing effect.

[0093] In some embodiments, if there is still fire in the target area after the fire extinguishing agent is used to extinguish the fire in the target area, the fire is extinguished in the target area through an external water source; or if there is still fire in the target area after the fire is extinguished by an external water source, the fire is extinguished in the target area through a fire extinguishing agent.

[0094] It is understandable that when a fire first occurs in the target area of ​​the energy storage cabin 11, a fire extinguishing agent or an external water source can be used to extinguish the fire in the energy storage cabin 11. However, since the fire extinguishing agent of perfluorohexanone has a better fire extinguishing effect than water, a fire extinguishing agent can be used to extinguish the fire in the target area of ​​the energy storage cabin 11. Optionally, since the volume of the fire extinguishing agent in the fire extinguishing device 121 is limited, after the fire extinguishing agent is exhausted or after the fire extinguishing agent is sprayed for a preset number of times / preset duration, the present embodiment can introduce an external water source to extinguish the fire in the energy storage cabin 11 through the driving device 131. Correspondingly, when a fire first occurs in the target area of ​​the energy storage cabin 11, an external water source can also be used to extinguish the fire in the energy storage cabin 11. Optionally, after spraying the external water source for a preset duration / preset number of times, the present embodiment can introduce a fire extinguishing agent to extinguish the fire in the energy storage cabin 11. From the above, it can be seen that the present embodiment can accurately suppress the fire in the target area through a variety of methods such as fire extinguishing agents and external water sources, rather than using a flooding fire extinguishing method for the entire energy storage compartment 11 after the fire extinguishing agent is exhausted, thereby improving the fire extinguishing effect on the target area, wherein the preset number of times or preset duration is not specifically limited here.

[0095] It should be noted that, since the end of the driving device 131 away from the external water source is connected to the first end of the delivery pipeline 15, the fire extinguishing agent and the external water source are delivered to the energy storage cabin 11 using the same delivery pipeline 15, which is equivalent to the driving device 131 not needing to re-establish the pipeline connection with the target area of ​​the energy storage cabin 11 on the side away from the external water source, thereby reducing the internal occupied space of the energy storage device 10 and improving the maintenance efficiency and fire fighting effect. In addition, since the external water source is delivered to the target area of ​​the energy storage cabin 11 through the delivery pipeline 15, after the external water source enters the target area of ​​the energy storage cabin 11, it can be extinguished by spraying with a nozzle in the same manner as the fire extinguishing agent. Compared with the related art, the purpose of introducing an external water source is to use a flooding fire extinguishing method for the energy storage device 10. In this embodiment, the driving device 131 is used to introduce an external water source and spray the target area of ​​the energy storage cabin 11 to achieve precise fire extinguishing in a local area, without using an external water source to fully cover the energy storage cabin 11, thereby improving the fire extinguishing effect.

[0096] In some embodiments, see Figure 3 , Figure 3It is a third structural diagram of the energy storage device provided in the embodiment of the present application. The energy storage device 10 may also include a fire water interface 16, which can be used to introduce fire water into the energy storage cabin 11. The processor 14 can be electrically connected to the fire water interface. The processor 14 can also be used to execute: if the target area of ​​the energy storage cabin 11 is extinguished by the fire extinguishing agent and / or the external water source, and there is still a fire in the target area of ​​the energy storage cabin 11, then the fire water interface 16 is controlled to introduce fire water to flood the energy storage cabin 11 for fire extinguishing, wherein the fire water is equivalent to the external water source and is drawn from the fire water tank through a pipeline. In other words, when the fire in the target area of ​​the energy storage cabin 11 is large and the spraying method can no longer meet the fire extinguishing needs, the firefighting personnel can access the fire water interface 16 to introduce fire water into the energy storage cabin 11, thereby achieving full coverage of the energy storage cabin 11 and ensuring the fire safety of the energy storage device 10.

[0097] As can be seen from the above, the energy storage device 10 in this embodiment includes the first fire protection system 12 and the second fire protection system 13, so that the fire protection of the energy storage device 10 is achieved through the combined fire suppression method of the first fire protection system 12 and the second fire protection system 13, and the fire safety of the energy storage device 10 is guaranteed. In addition, this embodiment also includes a fire water interface 16 that can introduce fire water to achieve flooding treatment of the energy storage cabin 11. In the case where the first fire protection system 12 and the second fire protection system 13 cannot be used to extinguish the fire, the energy storage device 10 can still be protected by flooding fire extinguishing treatment.

[0098] In addition, by using the same delivery pipeline 15 for the fire extinguishing agent of the fire extinguishing device 121 and the external water source introduced by the driving device 131, it is possible to achieve a spraying fire extinguishing method of two fire extinguishing media in the target area of ​​the energy storage cabin 11, and it is possible to reduce the connecting pipeline between the driving device 131 and the energy storage cabin 11 after the external water source is introduced, and reduce the complexity of the internal pipelines and the occupied space of the energy storage device 10. In addition, in addition to using the fire extinguishing agent for fire extinguishing, the energy storage cabin 11 is not directly flooded with fire water, but the external water source is introduced through the driving device 131 to continue to extinguish the fire in the energy storage cabin 11 by spraying, which can maintain the local area fire extinguishing of the target area of ​​the energy storage cabin 11 under the premise of ensuring the long-term fire suppression of the energy storage cabin 11, improve the fire extinguishing accuracy and effect, and can protect the area in the energy storage cabin 11 where no fire occurs.

[0099] The above embodiment realizes cabin-level fire protection for the energy storage cabin 11 through the combined fire suppression of the first fire protection system and the second fire protection system. The above embodiment is further described in detail below.

[0100] In some embodiments, the energy storage compartment 11 may include a battery compartment, and the battery compartment may include a first detection component and a first alarm. The processor 14 may be electrically connected to the first detection component and the first alarm, respectively, and the processor 14 may also be used to execute: if a trigger signal from the first detection component is received, the first alarm is controlled to send a fire alarm signal.

[0101] Optionally, the first detection component may include a combination of one or more of a temperature detector, a smoke detector, a combustible gas detector, and a carbon monoxide detector. The processor 14 is electrically connected to the battery compartment. Specifically, the processor 14 is electrically connected to the temperature detector, the smoke detector, the combustible gas detector, the carbon monoxide detector, and the first alarm, respectively. The processor 14 may also be used to execute:

[0102] If a first trigger signal from a temperature detector, a smoke detector, a combustible gas detector or a carbon monoxide detector is received, the first alarm is controlled to send out a fire alarm signal;

[0103] If a second trigger signal is received from the temperature detector and the smoke detector, or a third trigger signal is received from the temperature detector and the combustible gas detector, the first alarm is controlled to send out a fire alarm signal and determine that a fire occurs in the battery compartment.

[0104] In some embodiments, if a fire is determined in the battery compartment through detection by the first detection component and the first alarm, the fire extinguishing device is controlled to transport the fire extinguishing agent into the battery compartment through the delivery pipeline, so as to extinguish the fire in the battery compartment with the fire extinguishing agent; or the driving device is controlled to transport the external water source into the battery compartment through the delivery pipeline, so as to extinguish the fire in the battery compartment with the external water source.

[0105] It should be noted that if the temperature detector detects that the temperature in the battery compartment is higher than the preset temperature threshold, it will send a first trigger signal; if the smoke detector detects that the smoke concentration in the battery compartment is higher than the preset concentration threshold, it will send a first trigger signal; if the combustible gas detector detects that the combustible gas concentration is too high, it will send a first trigger signal; if the carbon monoxide detector detects that the carbon monoxide content is too high, it will send a first trigger signal. If any of the temperature detector, smoke detector, combustible gas detector and carbon monoxide detector triggers the first trigger signal, it means that there is no fire in the battery compartment. The processor 14 controls the first alarm to send a fire alarm signal based on the first trigger signal to remind the user that the battery compartment has a fire risk, so that the user can make corresponding fire warning protection based on the fire warning. Among them, the first alarm can be an audible and visual alarm. In addition, if any of the temperature detector, smoke detector, combustible gas detector and carbon monoxide detector triggers the first trigger signal, it cannot be determined that there is a fire in the battery compartment. It may be that any of the detectors fails and sends a false alarm signal. Therefore, the fire alarm signal sent by the first alarm can enable the user to confirm whether there is a fire in the battery compartment and take corresponding countermeasures.

[0106] In some embodiments, if the combustible gas detector detects that the concentration of combustible gas is too high, the processor 14 can control the first alarm to send a fire alarm signal while controlling the fan of the energy storage device 10 to turn on, turn off the air conditioner, and unlock the access control system of the energy storage device 10, thereby discharging the combustible gas from the battery compartment and reducing the risk of fire.

[0107] In some embodiments, if the temperature detector and the smoke detector in the battery compartment are triggered and responded at the same time, a second trigger signal is issued; or if the temperature detector and the combustible gas detector in the battery compartment are triggered and responded at the same time, a third trigger signal is issued. When the processor 14 receives the second trigger signal or the third trigger signal, it means that the temperature in the battery compartment is too high, and the smoke concentration is too high or the combustible gas concentration is too high, then it is determined that a fire has occurred in the battery compartment, and while controlling the first alarm to send a fire alarm signal, the fan is turned off, and the battery compartment is extinguished by a fire extinguishing agent or an external water source. It should be noted that since at least two of the temperature detector, the smoke detector, the combustible gas detector and the carbon monoxide detector are triggered and responded at the same time, such as the temperature detector and the smoke detector are triggered and responded at the same time or the temperature detector and the combustible gas detector are triggered and responded at the same time, since the probability of false alarms of at least two detectors at the same time is low, it means that a fire has occurred in the battery compartment at this time.

[0108] Specifically, if the battery compartment is extinguished by a fire extinguishing agent, the drive device and the drive device valve need to be controlled to count down to open during the process of spraying the fire extinguishing agent. The drive device valve is opened after 9 minutes of countdown, and the drive device is opened after 10 minutes of countdown, so as to spray the battery compartment with an external water source to extinguish the fire. It should be noted that in the process of spraying the fire extinguishing agent with the fire extinguishing agent, due to the limited volume of the fire extinguishing agent, it is necessary to count down the opening of the drive device and the drive device valve in advance, and extinguish the fire through an external water source after 10 minutes of countdown to ensure the fire safety of the battery compartment. It should be noted that the opening mode of the fire extinguishing device is delayed start, and the factory default delay is 30 seconds, which can also be adjusted accordingly within 0-30 seconds. During the fire extinguishing process, the venting do not enter indicator light can also be turned on to avoid the danger of inhaling toxic gases.

[0109] In some embodiments, the energy storage compartment 11 may also include an electrical compartment, which may include a second detection component and a second alarm. The processor 14 is electrically connected to the second detection component and the second alarm, respectively. The processor 14 may also be used to execute: if a trigger signal from the second detection component is received, the second alarm is controlled to send a fire alarm signal.

[0110] Optionally, the second detection component may include a temperature detector and / or a smoke detector, and the processor 14 is electrically connected to the electrical compartment. Specifically, the processor 14 is electrically connected to the temperature detector, the smoke detector and the second alarm respectively. The processor 14 can also be used to execute: if a fourth trigger signal from the temperature detector or the smoke detector is received, the second alarm is controlled to send a fire alarm signal, so that the fire safety of the electrical compartment can be monitored in real time. And through the detected indicators, the corresponding fire measurement is judged to achieve early detection, early warning, and early intervention functions, thereby further improving the fire protection of energy storage equipment.

[0111] In this embodiment, by using the same delivery pipeline 15 for the fire extinguishing agent and the external water source, the spraying fire extinguishing method of two fire extinguishing media can be realized in the battery compartment, and the connecting pipeline between the driving device 131 and the battery compartment after the external water source is introduced can be reduced, reducing the complexity of the internal pipelines and the occupied space of the energy storage device 10. In addition, in addition to using the fire extinguishing agent for fire extinguishing, the battery compartment is not directly flooded with fire water, but the external water source is introduced through the driving device 131 to continue to extinguish the fire in the battery compartment by spraying, which can maintain the fire extinguishing of the local area of ​​the battery compartment under the premise of ensuring the long-term fire suppression of the battery compartment, realize the cabin-level fire protection of the energy storage device 10, and improve the accuracy and effect of fire extinguishing.

[0112] Furthermore, on the basis of cabin-level fire protection for energy storage equipment, cluster-level fire protection can also be performed for energy storage equipment. Specifically, the battery cabin can include a battery pack assembly and a high-voltage pack assembly.

[0113] In some embodiments, the battery pack assembly includes multiple battery pack fire protection zones, the high-voltage pack assembly includes multiple high-voltage pack fire protection zones, and each battery pack fire protection zone and each high-voltage pack fire protection zone are provided with an aspirating composite detector. The battery pack assembly may include 10 battery clusters, with each two battery clusters as one battery pack fire protection zone, that is, the battery pack assembly may include 5 battery pack fire protection zones. An aspirating composite detector is provided on the top of each two battery clusters, that is, each battery pack fire protection zone, to detect thermal runaway fire signals in each battery pack fire protection zone.

[0114] Specifically, the processor is further used to execute: if the target air-inhaling composite detector sends out a secondary alarm signal or a tertiary alarm signal, control the first alarm to send out a fire alarm signal, wherein the target air-inhaling composite detector is any air-inhaling composite detector in the battery compartment;

[0115] If the target air-breathing composite detector sends out a level 4 alarm signal, the control alarm sends out a fire alarm signal and determines that a fire has occurred in the target battery pack fire protection zone or the target high-voltage pack fire protection zone corresponding to the target air-breathing composite detector.

[0116] In some embodiments, if a fire is detected in the target battery pack fire protection zone or the target high-voltage pack fire protection zone, the fire extinguishing device is controlled to transport the fire extinguishing agent through the delivery pipeline to the target battery pack fire protection zone or the target high-voltage pack fire protection zone, so as to perform fire extinguishing treatment with the fire extinguishing agent; or the driving device is controlled to transport the external water source through the delivery pipeline to the target battery pack fire protection zone or the target high-voltage pack fire protection zone, so as to perform fire extinguishing treatment with the external water source.

[0117] It should be noted that the detection principle of the air-breathing composite detector can be: the air-breathing composite detector monitors the temperature, carbon monoxide concentration, electrolyte concentration and smoke concentration of the battery pack fire protection zone and the high-voltage pack fire protection zone.

[0118] Optionally, if the temperature is lower than a first temperature threshold such as 55°, the carbon monoxide concentration is lower than a first concentration threshold such as 800, and the electrolyte concentration is lower than a second concentration threshold such as 3900, the suction pump of the absorption type composite detector is turned on, and the air intake valve is controlled to be energized. At this time, the suction type composite detector sends out a first-level alarm signal, wherein the first-level alarm signal is a normal detection signal. During the cyclic detection process of the suction type composite detector, if the suction type composite detector always sends out a first-level alarm signal, it means that there is no fire and the fire protection system linkage will not be triggered.

[0119] Optionally, if the temperature is greater than or equal to the first temperature threshold, such as 55°, the carbon monoxide concentration is greater than or equal to the first concentration threshold, such as 800, and the electrolyte concentration is greater than or equal to the second concentration threshold, such as 3900, a second-level alarm signal is issued; if the temperature is greater than or equal to the second temperature threshold, such as 65°, the carbon monoxide concentration is greater than or equal to the third concentration threshold, such as 3500, and the smoke concentration is greater than or equal to the fourth concentration threshold, such as 6000, a third-level alarm signal is issued. It should be noted that when the aspirating composite detector issues a second-level alarm signal or a third-level alarm signal, it indicates that there is a fire risk in the area corresponding to the aspirating composite detector, so the first alarm is controlled to issue a fire alarm signal. Among them, the second-level alarm signal and the third-level alarm signal are early warning signals. If the aspirating composite detector sends out a second-level alarm signal or a third-level alarm signal, it means that there is a risk of fire in the area corresponding to the aspirating composite detector, and the fire risk is high. At this time, it is necessary to use the fire alarm signal to remind the user to take corresponding fire prevention measures to avoid fire in the area corresponding to the aspirating composite detector. At this time, the fire linkage equipment can be activated, such as shutting down the ventilation system, starting the smoke exhaust fan, etc.

[0120] Optionally, if the temperature is greater than or equal to a third temperature threshold value such as 75°, the carbon monoxide concentration is greater than or equal to a third concentration threshold value such as 3500, the electrolyte concentration is greater than or equal to a second concentration threshold value such as 3900, and the smoke concentration is greater than or equal to a fourth concentration threshold value such as 6000, a level 4 alarm signal is issued. Among them, the level 4 alarm signal is a fire confirmation signal. If the air-breathing composite detector issues a level 4 alarm signal, it means that a fire has occurred in the area corresponding to the air-breathing composite detector. At this time, while controlling the first alarm to issue a fire alarm signal, it is necessary to extinguish the target battery pack fire protection zone or the target high-voltage pack fire protection zone corresponding to the target air-breathing composite detector through the first fire protection system or the second fire protection system, that is, to achieve pack-level fire extinguishing of the fire area through a combined fire suppression method of a fire extinguishing agent and / or an external water source, so as to achieve pack-level fire protection of the battery pack assembly or the high-voltage pack assembly in the battery compartment, thereby achieving precise fire extinguishing of the pack-level area. Among them, there may be more than one area where a fire occurs in the battery pack fire protection zone or the high-voltage pack fire protection zone. The zone control valve corresponding to the area can be controlled to open, so that the fire extinguishing agent and the external water source can be accurately sprayed on the area during the spraying process. Compared with the method of flooding with fire water or full coverage spraying of the entire cabin area, the fire extinguishing accuracy can be improved.

[0121] In some embodiments, the process of extinguishing a fire on a target battery pack assembly or a target high-voltage pack assembly is as follows: when the target air-breathing composite detector detects a level-four alarm signal for the first time, the fire extinguishing device is controlled to spray the fire extinguishing agent for 40 seconds, and a second detection is performed after standing for 5 minutes; the target battery pack assembly or the target high-voltage pack assembly is detected for the second time to see if it is a level-four alarm signal; if so, the fire extinguishing agent is continued to be sprayed for 40 seconds, and a third detection is performed after standing for 5 minutes; if not, spraying is not continued; during the third detection, see if it is a level-four alarm signal; if so, the water pump valve and the water pump are turned on, and the water pump is turned on for 20 minutes to spray water for fire extinguishing; if not, spraying is not continued.

[0122] Optionally, the electrical compartment may include a junction cabinet, and an aspirating composite detector may be provided in the area corresponding to the junction cabinet for fire detection. Specifically, the process of extinguishing a fire in the junction cabinet is as follows: when the target aspirating composite detector detects a level 4 alarm signal for the first time, the fire extinguishing device is controlled to spray the fire extinguishing agent for 40 seconds, and a second detection is performed after standing for 5 minutes; the second detection of the junction cabinet is detected to see whether it is a level 4 alarm signal; if so, the fire extinguishing agent is continuously sprayed for 40 seconds and the spraying is completed; if not, the spraying is not continued.

[0123] In the above embodiment, the fire control of the energy storage device 10 is in automatic mode, that is, automatic fire extinguishing is performed based on the detection data of the detector, and the energy storage device also includes an emergency start switch, and the processor is electrically connected to the emergency start switch. The processor can also be used to execute: if the emergency start switch is detected to be triggered, it is determined that a fire has occurred in the energy storage compartment. It is understandable that if the user finds that a fire has occurred in the energy storage device, the manual mode fire extinguishing can be achieved by closing the emergency start switch. Specifically, when the emergency start switch is closed, a manual mode start signal is sent to the processor; after receiving the start signal, the processor will turn off the fan, start the alarm in linkage, forcibly cut off the electrical equipment in the energy storage compartment, and use fire extinguishing agents or external water sources to extinguish the fire in the energy storage compartment.

[0124] To further introduce the energy storage device, the present application embodiment also provides a fire control method, which is applied to the energy storage device. Figure 4 , Figure 4 : is a flow chart of the fire control method provided in the embodiment of the present application. The specific flow of the fire control method can be as follows:

[0125] 101. If a fire is detected in the target area of ​​the energy storage cabin, the first fire fighting system or the second fire fighting system is controlled to transport the target suppressant for extinguishing the fire into the target area through the transport pipeline, so as to extinguish the fire in the target area through the target suppressant.

[0126] In this embodiment, the energy storage device 10 may include an energy storage compartment 11 , a first fire fighting system 12 , a second fire fighting system 13 and a transmission pipeline 15 .

[0127] The first fire fighting system 12 and the second fire fighting system 13 can both deliver the target suppressant for extinguishing the fire into the target area through the delivery pipeline 15, so as to extinguish the fire in the target area through the target suppressant. The target suppressants delivered by the first fire fighting system 12 and the second fire fighting system 13 can be different target suppressants, and specifically, the target suppressants can include fire extinguishing agents and external water sources.

[0128] The first fire fighting system 12 may include a fire extinguishing device 121, wherein a fire extinguishing agent is stored in the fire extinguishing device 121, and the fire extinguishing agent may be a perfluorohexanone fire extinguishing agent. Of course, the fire extinguishing agent in the fire extinguishing device 121 may also be other types of fire extinguishing agents such as aerosol, inert gas, carbon dioxide, dry powder, heptafluoropropane, etc., and the type of the fire extinguishing agent is not specifically limited here.

[0129] In some embodiments, the first fire fighting system includes a fire extinguishing device, in which a fire extinguishing agent is stored, a first end of a delivery pipeline is connected to the fire extinguishing device, and a second end of the delivery pipeline extends into the energy storage compartment; the second fire fighting system includes a driving device, a first end of the driving device is connected to a first end of the delivery pipeline, and a second end of the driving device is connected to an external water source. Optionally, if a fire is detected in the target area, the fire extinguishing device is controlled to deliver the fire extinguishing agent to the target area through the delivery pipeline, or the driving device is controlled to deliver the external water source to the target area through the delivery pipeline, so as to extinguish the fire in the target area with the fire extinguishing agent or the external water source.

[0130] The first end of the delivery pipeline 15 is connected to the fire extinguishing device 121, and the second end of the delivery pipeline 15 extends into the energy storage cabin 11. Therefore, the fire extinguishing agent in the fire extinguishing device 121 can be delivered to the energy storage cabin 11 through the delivery pipeline 15, so that when a fire occurs in the energy storage cabin 11, the fire extinguishing agent is used to extinguish the fire in the energy storage cabin 11. Specifically, if a fire occurs in the target area of ​​the energy storage cabin 11, the fire extinguishing agent is used to extinguish the fire in the target area of ​​the energy storage cabin 11, thereby achieving precise fire extinguishing of the target area, while other areas of the energy storage cabin 11 other than the target area where no fire occurs are not extinguished, so that other areas will not be affected by the fire extinguishing agent and protection of other areas is achieved.

[0131] It should be noted that since the fire extinguishing device 121 is arranged in the first fire protection system 12, and the first fire protection system 12 is arranged in the energy storage device 10, in order to ensure the rationality of the assembly of various components in the energy storage device 10, the space occupied by the fire extinguishing device 121 will not be too large. Therefore, the volume of the fire extinguishing agent stored in the fire extinguishing device 121 is limited. Under normal circumstances, the volume of the fire extinguishing agent stored in the fire extinguishing device 121 can support one to two fire extinguishing treatments on the energy storage cabin 11.

[0132] In order to ensure that the energy storage device 10 can suppress multiple fires, in addition to realizing fire protection of the energy storage cabin 11 through the first fire protection system 12, this embodiment also provides a second fire protection system 13, which includes a driving device 131, a first end of which is connected to the first end of the delivery pipeline 15, and a second end of which is connected to an external water source. The driving device 131 can be a device driven by a motor or other power source, such as a water pump.

[0133] Specifically, when a fire occurs in the target area of ​​the energy storage cabin 11, the driving valve of the driving device 131 is opened to introduce the external water source into the target area of ​​the energy storage cabin 11 through the delivery pipeline 15, so that the target area of ​​the energy storage cabin 11 can be extinguished by the external water source. Optionally, the external water source can be fire water, for example, the second end of the driving device 131 is connected to a fire water tank through a pipeline, and when a fire occurs in the target area of ​​the energy storage cabin 11, the driving device 131 introduces the external water source into the target area for fire extinguishing.

[0134] Among them, after a fire occurs in the target area of ​​the energy storage cabin 11, the energy storage cabin 11 can be extinguished by a fire extinguishing agent or an external water source. In some embodiments, after a fire occurs in the target area of ​​the energy storage cabin 11, a fire extinguishing agent can be used to extinguish the fire first, and then an external water source can be used to extinguish the fire after the fire extinguishing agent is exhausted. The specific fire extinguishing strategy is not specifically limited here and can be set accordingly according to actual conditions. Among them, the fire extinguishing agent or the external water source are both transported to the target area through a delivery pipeline.

[0135] In some embodiments, if there is still fire in the target area after the fire extinguishing agent is used to extinguish the fire in the target area, the fire is extinguished in the target area through an external water source; or if there is still fire in the target area after the fire is extinguished by an external water source, the fire is extinguished in the target area through a fire extinguishing agent.

[0136] It is understandable that when a fire first occurs in the target area of ​​the energy storage cabin 11, a fire extinguishing agent or an external water source can be used to extinguish the fire in the energy storage cabin 11. However, since the fire extinguishing agent of perfluorohexanone has a better fire extinguishing effect than water, a fire extinguishing agent can be used to extinguish the fire in the target area of ​​the energy storage cabin 11. Optionally, since the volume of the fire extinguishing agent in the fire extinguishing device 121 is limited, after the fire extinguishing agent is exhausted or after the fire extinguishing agent is sprayed for a preset number of times / preset duration, the present embodiment can introduce an external water source to extinguish the fire in the energy storage cabin 11 through the driving device 131. Correspondingly, when a fire first occurs in the target area of ​​the energy storage cabin 11, an external water source can also be used to extinguish the fire in the energy storage cabin 11. Optionally, after spraying the external water source for a preset duration / preset number of times, the present embodiment can introduce a fire extinguishing agent to extinguish the fire in the energy storage cabin 11. From the above, it can be seen that the present embodiment can accurately suppress the fire in the target area through a variety of methods such as fire extinguishing agents and external water sources, rather than using a flooding fire extinguishing method for the entire energy storage compartment 11 after the fire extinguishing agent is exhausted, thereby improving the fire extinguishing effect on the target area, wherein the preset number of times or preset duration is not specifically limited here.

[0137] It should be noted that, since the end of the driving device 131 away from the external water source is connected to the first end of the delivery pipeline 15, the fire extinguishing agent and the external water source are delivered to the energy storage cabin 11 using the same delivery pipeline 15, which is equivalent to the driving device 131 not needing to re-establish the pipeline connection with the target area of ​​the energy storage cabin 11 on the side away from the external water source, thereby reducing the internal occupied space of the energy storage device 10 and improving the maintenance efficiency and fire fighting effect. In addition, since the external water source is delivered to the target area of ​​the energy storage cabin 11 through the delivery pipeline 15, after the external water source enters the target area of ​​the energy storage cabin 11, it can be extinguished by spraying with a nozzle in the same manner as the fire extinguishing agent. Compared with the related art, the purpose of introducing an external water source is to use a flooding fire extinguishing method for the energy storage device 10. In this embodiment, the driving device 131 is used to introduce an external water source and spray the target area of ​​the energy storage cabin 11 to achieve precise fire extinguishing in a local area, without using an external water source to fully cover the energy storage cabin 11, thereby improving the fire extinguishing effect.

[0138] In some embodiments, the energy storage device 10 may also include a fire water interface 16, which can be used to introduce fire water into the energy storage cabin 11. The processor 14 can be electrically connected to the fire water interface, and the processor 14 can also be used to execute: if the target area of ​​the energy storage cabin 11 is extinguished by fire extinguishing agents and / or external water sources, and there is still a fire in the target area of ​​the energy storage cabin 11, then the fire water interface 16 is controlled to introduce fire water to flood the energy storage cabin 11 for fire extinguishing, wherein the fire water is equivalent to the external water source and is drawn from the fire water tank through a pipeline. In other words, when the fire in the target area of ​​the energy storage cabin 11 is large and the spraying method can no longer meet the fire extinguishing needs, the firefighting personnel can access the fire water interface 16 to introduce fire water into the energy storage cabin 11, thereby achieving full coverage of the energy storage cabin 11 and ensuring the fire safety of the energy storage device 10.

[0139] In some embodiments, the energy storage compartment 11 may include a battery compartment, and the battery compartment may include a first detection component and a first alarm. Specifically, if a trigger signal from the first detection component is received, the first alarm is controlled to send a fire alarm signal. The first detection component may include a combination of one or more of a temperature detector, a smoke detector, a combustible gas detector, and a carbon monoxide detector.

[0140] Optionally, if a first trigger signal is received from a temperature detector, a smoke detector, a combustible gas detector or a carbon monoxide detector, the first alarm is controlled to send out a fire alarm signal.

[0141] Optionally, if a second trigger signal is received from the temperature detector and the smoke detector, or a third trigger signal is received from the temperature detector and the combustible gas detector, the first alarm is controlled to send out a fire alarm signal, and it is determined that a fire occurs in the battery compartment.

[0142] In some embodiments, if a fire is determined in the battery compartment through detection by the first detection component and the first alarm, the fire extinguishing device is controlled to transport the fire extinguishing agent into the battery compartment through the delivery pipeline, so as to extinguish the fire in the battery compartment with the fire extinguishing agent; or the driving device is controlled to transport the external water source into the battery compartment through the delivery pipeline, so as to extinguish the fire in the battery compartment with the external water source.

[0143] In some embodiments, the energy storage compartment 11 may also include an electrical compartment, which may include a second detection component and a second alarm. Specifically, if a trigger signal from the second detection component is received, the second alarm is controlled to send a fire alarm signal. The second detection component may include a temperature detector and / or a smoke detector.

[0144] Optionally, if a fourth trigger signal from a temperature detector or a smoke detector is received, the second alarm is controlled to send a fire alarm signal, so that the fire safety of the electrical compartment can be monitored in real time. And the corresponding firefighting measures are taken based on the detected indicators to achieve early detection, early warning, and early intervention functions, thereby further improving the fire protection of energy storage equipment.

[0145] In some embodiments, the battery pack assembly includes multiple battery pack fire protection zones, the high-voltage pack assembly includes multiple high-voltage pack fire protection zones, and each battery pack fire protection zone and each high-voltage pack fire protection zone are provided with an aspirating composite detector. The battery pack assembly may include 10 battery clusters, with each two battery clusters as one battery pack fire protection zone, that is, the battery pack assembly may include 5 battery pack fire protection zones. An aspirating composite detector is provided on the top of each two battery clusters, that is, each battery pack fire protection zone, to detect thermal runaway fire signals in each battery pack fire protection zone.

[0146] Optionally, if the target air-suctioning composite detector sends out a secondary alarm signal or a tertiary alarm signal, the first alarm is controlled to send out a fire alarm signal, wherein the target air-suctioning composite detector is any air-suctioning composite detector in the battery compartment.

[0147] Optionally, if the target air-breathing composite detector sends out a level 4 alarm signal, the alarm is controlled to send out a fire alarm signal, and determine that a fire occurs in the target battery pack fire protection zone or the target high-voltage pack fire protection zone corresponding to the target air-breathing composite detector.

[0148] In some embodiments, if a fire is detected in the target battery pack fire protection zone or the target high-voltage pack fire protection zone, the fire extinguishing device is controlled to transport the fire extinguishing agent through the delivery pipeline to the target battery pack fire protection zone or the target high-voltage pack fire protection zone, so as to perform fire extinguishing treatment with the fire extinguishing agent; or the driving device is controlled to transport the external water source through the delivery pipeline to the target battery pack fire protection zone or the target high-voltage pack fire protection zone, so as to perform fire extinguishing treatment with the external water source.

In addition, in addition to using the fire extinguishing agent for fire extinguishing, the energy storage cabin 11 is not directly flooded with fire water, but the external water source is introduced through the driving device 131 to continue to extinguish the fire in the energy storage cabin 11 by spraying, which can maintain the fire extinguishing of the local area of ​​the energy storage cabin 11 under the premise of ensuring the long-term fire suppression of the energy storage cabin 11, thereby improving the accuracy and effect of fire extinguishing.
