As a flexible and efficient energy storage solution, energy storage containers are usually used to store and manage electricity to improve the stability and efficiency of the power grid.

[0003] In the prior art, a threshold-based monitoring method is usually adopted to judge the safety state of the energy storage system. By setting the threshold of the monitored parameter, an alarm is triggered when the monitored data exceeds the threshold.

[0044] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Invention

[0045] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals 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. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0046] As an efficient energy storage solution, energy storage containers are widely used in fields such as power grid regulation, renewable energy grid connection, and emergency power supplies. However, the centralized use of a large number of batteries in energy storage containers also brings potential safety hazards, especially the problem of battery thermal runaway. Thermal runaway refers to a dangerous phenomenon in which the temperature of a battery rises sharply when affected by external or internal factors, leading to battery fire or even explosion. This not only poses a threat to the energy storage system itself but may also cause serious impacts on the surrounding environment and personnel safety.

[0047] In order to effectively prevent and respond to the fire risk in energy storage containers, reasonable fire-fighting equipment and facilities need to be configured. Traditional fire-fighting systems usually rely on equipment such as combustible gas detectors, smoke detectors, temperature sensors, or other gas detectors that meet the standards for monitoring, and then judge whether the detected value reaches a pre-set threshold to trigger a fire alarm. However, these detection devices can often only provide an alarm when a fire has occurred or is about to occur, and cannot effectively identify and warn of early abnormal situations, so that they cannot respond in time to changes in the fire source, resulting in the inability to effectively control the fire situation in the initial stage of the fire and missing the best intervention opportunity. In addition, the individual real-time detection values may not accurately reflect the actual state of the battery system, and only through threshold judgment, false alarms or missed alarms may also occur.

[0048] To solve the above technical problems, a fire warning control method provided by an embodiment of the present application, based on real-time monitoring of thermal runaway information related to the fire protection of energy storage containers, when any abnormal data is identified, misjudgment determination is performed through the change parameters of the abnormal data. When it is determined that there is no misjudgment, the warning positioning information and warning level are further determined, and then the fire protection equipment is controlled through the warning positioning information and warning level. On the one hand, the embodiment of the present application performs misjudgment through the change parameters of abnormal data, eliminating the risk of false alarms; on the other hand, the embodiment of the present application also locates the fire source. According to the fire source, not only can the fire be accurately controlled, improving the fire protection accuracy and effect, avoiding greater dangers, but also the safety of the energy storage system can be improved. At the same time, effective measures can be taken before the fire occurs to reduce losses, ensure the safety of personnel and equipment, and overall improve the fire safety level of the energy storage container.

[0049] The following uses specific embodiments to elaborate in detail on the technical solution of the present application and how the technical solution of the present application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the present application in conjunction with the accompanying drawings.

[0050] It should be noted that the fire warning control method provided by an embodiment of the present application is applied to the fire protection host in the fire protection unit of the energy storage container. The energy storage container also includes a battery compartment, and the battery compartment includes multiple battery clusters, and each battery cluster is provided with multiple battery packs.

[0051] It can be understood that the fire protection unit is a system in the energy storage container dedicated to monitoring and handling fire risks. The fire protection host is the core component of this system, responsible for receiving and processing data from various sensors, and making decisions based on these data. The battery compartment is an area inside the energy storage container for storing batteries. Inside the battery compartment, the batteries are usually organized in clusters, each battery cluster consists of multiple battery packs, and each battery pack contains several single cells. Such a hierarchical structure helps to improve the battery management efficiency and the overall reliability of the system. In this complex structure, the fire protection host executes the fire warning control method provided by an embodiment of the present application, by real-time monitoring various parameters related to the fire protection of the energy storage container inside the battery compartment, and judging whether there is a risk of thermal runaway by analyzing its numerical value, parameter change value, and duration, and then controlling the corresponding fire protection equipment to perform targeted responses to prevent the occurrence or spread of fire.

[0052] Exemplarily, Figure 1 is a flowchart of a fire warning control method provided by an embodiment of the present application. As Figure 1 shown, the fire warning control method provided by an embodiment of the present application may include:

[0053] S101. Obtain real-time monitoring data related to the fire protection of energy storage containers.

[0054] Exemplarily, real-time monitoring data is the basis of the entire fire warning system, which provides current status information about each battery component in the energy storage container. Optionally, the real-time monitoring data related to the fire protection of energy storage containers may include at least one of combustible gas concentration, battery temperature, smoke concentration, volatile organic compound (VOC) concentration, etc. These real-time monitoring data can be obtained through a composite detector or corresponding detectors. For example, combustible gas concentrations such as CO concentration, H2 concentration, etc., can be obtained through combustible gas detectors; battery temperature can be detected through temperature sensors; smoke concentration can be monitored through smoke detectors; VOC concentration can be monitored through composite gas detectors, etc.

[0055] In practical applications, various detectors can be installed in the battery compartment, battery cluster, and battery pack respectively according to actual needs to achieve compartment-level detection, cluster-level detection, and pack-level detection, so as to better carry out fire risk early warning and control.

[0056] S102. If it is determined that there is abnormal data in the real-time monitoring data, obtain the change parameters of the abnormal data; wherein, the change parameters include the parameter change value of the abnormal data within the target time period and / or the duration of the abnormal data.

[0057] Exemplarily, after the fire protection host obtains the real-time monitoring data, it will analyze these real-time monitoring data to determine whether there is abnormal data in the real-time monitoring data. Abnormal data may include a sudden increase in temperature, an increase in smoke concentration, or voltage fluctuations. When an abnormality is detected, the change parameters of these abnormal data are further obtained. Among them, the change parameters include the parameter change value of the abnormal data within the target time period and / or the duration of the abnormal data. The parameter change value refers to the magnitude of the parameter change amount of the abnormal data within the target time period, and the duration refers to the length of time that the abnormal situation has lasted. The change parameters are used to evaluate the change stability of the abnormal parameters, and then evaluate the authenticity and reliability of the data according to the change stability to avoid false triggering.

[0058] Optionally, in a possible embodiment, determining that there is abnormal data in the real-time monitoring data may include: if it is determined that the real-time monitoring data is not within the numerical range allowed for normal operation, it is determined that there is abnormal data in the real-time monitoring data.

[0059] Exemplarily, for each monitoring parameter (such as combustible gas concentration, battery temperature, smoke concentration, VOC concentration, etc.) monitored by each detector in the energy storage container, a numerical range allowed for normal operation can be predefined. These ranges are usually set based on the device's design specifications, the manufacturer's recommendations, and historical operation data. In some cases, these ranges may be dynamically adjusted according to environmental conditions, usage, or other factors to ensure their accuracy and effectiveness. During the execution of the fire warning control method, after the fire host obtains the real-time monitoring data, it compares the obtained real-time monitoring data with the corresponding preset normal operation range. If all the real-time monitoring data are within the normal operation range, it is considered that the operation is normal and no further measures need to be taken. If any one of the real-time monitoring data exceeds the normal operation range, it is considered that there is an abnormal situation, which means that a certain parameter has reached an unsafe level and may indicate potential risks. Once a certain data point is determined to be abnormal, it is marked and determined as abnormal data.

[0060] After marking the abnormal data, the change parameter of the abnormal parameter can be further obtained. Among them, the change parameter of the abnormal data can be determined by combining a sliding window or time series analysis. Specifically, the parameter change values of multiple time windows can be calculated, such as Δ1 (T0 - T1), Δ2 (T1 - T2), Δ3 (T2 - T3), etc. as the change parameters, and the change trend of the abnormal data can be described by multiple parameter change values. Based on this, it can be determined whether the abnormal data continues to increase or decrease, or whether there is a violent fluctuation, etc. In addition, the average value of the parameter change values of each time window within the target time period (such as average value = (Δ1 + Δ2 + Δ3 +.. + Δn) / n, where Δ1 is the difference between t0 and t1, Δ2 is the difference between t1 and t2, Δ3 is the difference between t2 and t3, Δn is the difference between tn-1 and tn, etc.), standard deviation, or cumulative value of the change rate, etc. can also be used as the parameter change value to judge whether it belongs to abnormal fluctuation. In addition, spike filtering can be adopted. When the single sampling value exceeds 3 times the average value of the adjacent 5 points, the Kalman filter is started to re-estimate the true value, and then the parameter change value used to evaluate the change trend of the abnormal data is calculated. Regarding the duration of the abnormal data, the timing can start at the initial moment when the abnormal data is detected or when it is about to reach the abnormal data range to obtain the duration of the abnormal data.

[0061] By first determining whether there is abnormal data in the real-time monitoring data, and when it is determined that there is abnormal data, then obtaining the change parameter of the abnormal parameter to be used to evaluate the authenticity and reliability of the abnormal data, it can not only effectively prevent false triggering and reduce the probability of false triggering, but also quickly identify and respond to abnormal situations in the energy storage container, especially those that may cause safety hazards, thereby improving the overall safety and reliability.

[0062] S103. If it is determined that the change parameter is not within the preset change limit range, the warning positioning information and warning level are determined according to the real-time monitoring data; the warning positioning information is used to indicate the position of the battery pack where thermal runaway occurs, and the warning level is used to indicate the urgency of the fire warning.

[0063] Exemplarily, in the embodiment of the present application, the change parameter of the abnormal data is obtained to further determine the reliability of the real-time monitoring data according to the change parameter of the abnormal data, so as to avoid false triggering. It can be understood that if there is a violent fluctuation in the value within a short period of time, it may be noise rather than a real event. Therefore, the real reliability of the abnormal data can be judged by determining whether the change parameter of the abnormal data is within the preset change limit range. If it is determined that the change parameter of the abnormal data is not within the preset change limit range, that is, it exceeds the safe change range, it indicates that the abnormal data is true, is a real abnormality, may have thermal runaway, and there is a greater fire risk, rather than false triggering. In this case, the fire host will determine the warning positioning information and warning level according to the obtained real-time monitoring data, so as to control the corresponding target fire-fighting equipment and control the thermal runaway phenomenon subsequently.

[0064] Optionally, in a possible embodiment, determining the warning positioning information and warning level according to the real-time monitoring data may include:

[0065] S1. Determine the warning positioning information according to the position of the detector of the abnormal data in the collected real-time monitoring data;

[0066] S2. Determine the parameter change value and duration of the real-time monitoring data, and determine the warning level according to the real-time monitoring data, the parameter change value of the real-time monitoring data, and the level interval corresponding to the duration.

[0067] Exemplarily, multiple sensors or detectors are usually arranged inside the energy storage container, and these devices are used to monitor the states of different areas. Each detector has its specific installation position and unique identifier. When abnormal data is detected and it is determined that it is not a false trigger, by identifying the position of the detector where the abnormal data comes from, the warning positioning information can be generated, and this warning positioning information accurately indicates the position of the battery pack or battery cluster where the abnormality occurs, which is crucial for rapid response and taking targeted measures.

[0068] Furthermore, all real-time monitoring data can be analyzed, the parameter change values and the duration of each real-time monitoring data can be determined, and the corresponding level intervals can be determined, so as to determine the warning level. Among them, in the embodiments of the present application, different level intervals are predefined, and these intervals are based on one or more combinations of the instantaneous values, parameter change values, and duration of the real-time monitoring data, corresponding to different warning levels respectively. Optionally, the warning level can be divided into three levels: low, medium, and high, or can be divided into multiple levels such as 1, 2, 3, 4... The embodiments of the present application do not make restrictions. Different parameter level intervals correspond to different warning levels and different fire protection measures are taken.

[0069] For example, the triggering conditions for a first-level warning can be any one of the following:

[0070] 1) The CO concentration ≥ 100×10 -5 and the concentration is less than 190×10 -6 ;

[0071] 2) The battery temperature ≥ 60°C and less than 70°C;

[0072] 3) The VOC concentration ≥ 0.6V;

[0073] 4) The smoke concentration ≥ 2mg / m 3 and the concentration is less than 5mg / m 3 .

[0074] The triggering conditions for a second-level warning can be any one of the following:

[0075] 1) The CO concentration satisfies the low alarm value of 190×10 -6 and the duration reaches 12s;

[0076] 2) The battery temperature satisfies the isothermal level 2 alarm value of 70°C and the duration reaches 12s;

[0077] 3) The VOC concentration satisfies the level 2 alarm value of 1.5 V and the duration reaches 12s;

[0078] 4) The VOC concentration satisfies a specific upward trend (for example, the parameter change value of the VOC concentration is greater than the preset value of 1V).

[0079] The triggering conditions for a third-level warning can be any one of the following:

[0080] 1) The CO concentration satisfies the high alarm value of 500×10 -6 and the duration reaches 6s;

[0081] 2) The battery temperature satisfies the isothermal level 3 alarm value of 80°C and the duration reaches 6s;

[0082] 3) The VOC concentration meets the 3rd - level alarm value of 2.0 V and the duration reaches 6 s;

[0083] 4) The smoke concentration meets the smoke alarm action value of 5 mg / m 3 .

[0084] The triggering conditions corresponding to the fourth - level early warning can be any one of the following:

[0085] 1) The battery temperature meets the fixed - temperature 4th - level alarm value of 90 °C and the duration reaches 5 s;

[0086] 2) The steady - state battery temperature is above 60 °C, and meets the temperature differential alarm value of 1 °C / s, and the duration is 10 s;

[0087] 3) The battery temperature meets the fixed - temperature 3rd - level alarm value of 80 °C, and the VOC concentration meets the 3rd - level alarm value of 2.0 V, and the duration is 10 s;

[0088] 4) The battery temperature meets the fixed - temperature 3rd - level alarm value of 80 °C, and the CO concentration meets the 3rd - level alarm value, and the duration reaches 10 s;

[0089] 5) The battery temperature meets the fixed - temperature 3rd - level alarm value of 80 °C, and the smoke concentration meets the smoke alarm action value of 5 mg / m 3 , and the duration reaches 10 s.

[0090] It should be noted that the above - mentioned division of early - warning levels and the triggering conditions corresponding to each early - warning level are only examples. In actual applications, reasonable level intervals can be set according to the installation positions, performances, etc. of each detector. The embodiments of the present application do not limit this.

[0091] By combining the detailed analysis of the detector position and real - time monitoring data, accurate early - warning positioning information and reasonable early - warning levels can be generated. This method not only improves the accuracy of anomaly detection but also ensures the effectiveness and timeliness of response measures, so as to facilitate subsequent adoption of different response strategies according to the early - warning positioning information and early - warning levels, such as activating specific fire - fighting equipment, notifying operators, or making system adjustments, etc., to minimize risks and losses.

[0092] S104. Control the target fire - fighting equipment according to the early - warning positioning information and early - warning level; wherein, the target fire - fighting equipment is the fire - fighting equipment associated with the battery pack that has a thermal runaway.

[0093] Exemplarily, once the early - warning positioning information and early - warning level are determined, the fire - fighting host can control the corresponding fire - fighting equipment to respond and achieve fire - fighting early - warning control.

[0094] Optionally, the target fire-fighting equipment is the fire-fighting equipment associated with the battery pack that has experienced thermal runaway. For example, according to different warning levels, the target fire-fighting equipment may include one or more of a fire-fighting medium spraying device, an explosion-proof fan, a fire water system, an alarm system, a communication device with a superior monitoring device, etc.

[0095] Exemplarily, the fire-fighting medium spraying device is usually used to quickly spray a fire-extinguishing medium (such as perfluoromethylhexane, etc.) to extinguish the fire source or reduce the temperature when a fire or overheating situation is detected. The explosion-proof fan is usually used to exhaust smoke, heat, harmful gases, etc. inside the energy storage container to reduce the internal pressure and prevent the risk of explosion. When the smoke concentration increases or harmful gases are detected, etc., the explosion-proof fan can be started to ensure the air quality and safety inside the container. The fire water system cools the equipment and suppresses the fire by spraying water. The water system usually includes sprinkler heads and water pumps and is usually used when large-area cooling or fire suppression is required. The fire water system can provide continuous water flow to reduce the temperature and prevent the spread of fire. The alarm system is usually used to emit audible and visual alarm signals when an abnormal situation is detected to alert the on-site personnel. When any abnormal situation is detected, the alarm system can immediately notify the on-site personnel so that they can take appropriate countermeasures. The communication device with the superior monitoring device is used to timely transmit information to the superior monitoring system when an abnormality occurs, facilitating remote monitoring and allowing managers to make decisions and take actions.

[0096] In the embodiment of the present application, one or more of a fire-fighting medium spraying device, an explosion-proof fan, a fire water system, an alarm system, a communication device with a superior monitoring device, etc. can be controlled for fire warning according to the warning positioning information and the warning level. For example, when the warning level is a first-level warning, background warning can be performed without performing other actions; when the warning level is a second-level warning, the energy storage container can be controlled to shut down, and background warning, telephone notification warning, on-site audible and visual alarm can be performed, and the ventilation and explosion-proof can also be controlled to start; when the warning level is a third-level warning, the energy storage container can be controlled to shut down, and background warning, telephone notification warning, on-site audible and visual alarm can be performed, and the ventilation and explosion-proof can also be controlled to close, and the fire-fighting medium spraying device can be controlled to spray; when the warning level is a fourth-level warning, on the basis of the control measures of the third-level warning, the fire water system is further used for water fire spraying, and the fire brigade is also reported.

[0097] When slight overheating is detected in the initial stage, it may only be necessary to start the explosion-proof fan and the alarm system. When a serious thermal runaway risk is detected, it may be necessary to activate the fire-fighting medium spraying device, the fire water system, and the communication device simultaneously to ensure a quick and effective response. By flexibly combining and controlling these fire-fighting equipment, comprehensive fire warning and response capabilities can be provided, maximizing the safety of the energy storage container and its surrounding environment.

[0098] Optionally, in a possible embodiment, controlling the target fire-fighting equipment according to the warning positioning information and the warning level may include:

[0099] S10. Determine the battery pack with thermal runaway according to the warning positioning information;

[0100] S20. If it is determined that the warning level does not reach the target level, determine the direct fire-fighting equipment of the battery pack with thermal runaway as the target fire-fighting equipment; the direct fire-fighting equipment is used to indicate the fire-fighting equipment set for directly controlling the battery pack with thermal runaway;

[0101] S30. If it is determined that the warning level reaches the target level, determine the adjacent battery packs of the battery pack with thermal runaway according to the warning positioning information, and determine that both the direct fire-fighting equipment of the battery pack with thermal runaway and the direct fire-fighting equipment of the adjacent battery packs are the target fire-fighting equipment;

[0102] S40. Control the target fire-fighting equipment.

[0103] Exemplarily, through real-time monitoring data, the specific location of the abnormal situation has been determined, that is, which battery pack has thermal runaway. That is to say, using the warning positioning information, the battery pack with thermal runaway can be accurately identified. Then, the current warning level is evaluated. If the warning level does not reach a preset target level (for example, it has not reached the severity level that requires large-scale intervention, such as less than or equal to the third-level warning), then relatively local response measures are taken. In this case, only the fire-fighting equipment used to directly control and handle the abnormal situation of this battery pack is determined as the target fire-fighting equipment. For example, if it is necessary to open the cluster-level sub-control valve of the fire-fighting medium spraying equipment, only the sub-control valve of the battery pack with thermal runaway is opened.

[0104] If the warning level reaches the target level (such as the fourth-level warning), it indicates that the abnormal situation may pose a threat to a larger area. At this time, the battery packs adjacent to the battery pack with thermal runaway can be identified first, and then, the direct fire-fighting equipment of the battery pack with thermal runaway and the direct fire-fighting equipment of the adjacent battery packs are activated simultaneously. For example, not only the sub-control valve of the battery pack with thermal runaway is opened, but also the sub-control valve of the adjacent battery packs is opened. This extended response helps prevent the thermal runaway from spreading to adjacent areas and avoid the spread of fire and greater damage.

[0105] Through this hierarchical response strategy, the fire-fighting equipment can be flexibly selected and controlled according to the severity and specific location of the abnormal situation. This method not only improves the accuracy and effectiveness of the response, but also minimizes the interference to the normal operation of the energy storage container. Through timely and appropriate intervention, the occurrence or spread of fire can be effectively prevented, and the safety of equipment and personnel can be protected.

[0106] The fire warning control method provided by the embodiments of this application can not only achieve early detection and warning by real-time monitoring and analyzing abnormal data in the energy storage container and conduct effective intervention when problems first appear, but also rule out the risk of false alarms and avoid false triggers by using the change parameters of the abnormal data. In addition, by accurately locating the position of the battery pack with thermal runaway and combining with a hierarchical response mechanism, it is possible not only to quickly take targeted measures to avoid unnecessary intervention and waste of resources, but also to flexibly adjust the response strategy according to the urgency of the abnormality to ensure reasonable allocation of resources, achieve a rapid and effective response, minimize potential damage, significantly improve the safety and operational reliability of the energy storage container, protect the safety of equipment, the surrounding environment and personnel, and at the same time reduce possible economic losses and downtime.

[0107] Figure 2 It is a schematic flow chart of another fire warning control method provided by the embodiments of this application. As Figure 2 shown, the fire warning control method provided by the embodiments of this application may include:

[0108] S201. Obtain real-time monitoring data related to the fire protection of the energy storage container.

[0109] S202. Determine whether there is abnormal data in the real-time monitoring data.

[0110] If so, execute step S203; if not, execute step S201.

[0111] S203. Obtain the change parameters of the abnormal data.

[0112] Among them, the change parameters include the parameter change value of the abnormal data within the target time period and / or the duration of the abnormal data.

[0113] S204. Determine whether the change parameters are within the preset change limit range.

[0114] If so, execute steps S205 - S206; if not, execute step S207.

[0115] S205. Determine the detector that collects the abnormal data and output a fault alarm message; among them, the fault alarm message is used to instruct the user to determine whether the detector that collects the abnormal data is a device fault.

[0116] S206. In response to the detector that collects the abnormal data not being a device fault, update the false alarm frequency of the detector that collects the abnormal data.

[0117] Exemplarily, if the change parameter of the abnormal parameter is within the preset change limit range, it means that the abnormal data may not be caused by actual thermal runaway or other dangerous situations, but may be a false trigger caused by a problem with the detector itself. In this case, the specific detector that collected the abnormal data can be identified, a fault alarm message can be generated and output to notify the user or maintenance personnel to remind the user to check the detector to determine whether the abnormal data is caused by a device failure of the detector. If it is not a device failure but a false alarm situation that exists in the device itself, the user can input information indicating that the detector that collected the abnormal data is not a device failure, and the fire host can, in response to this information, update the false alarm frequency record of the detector to better evaluate the reliability and accuracy of the detector in the future.

[0118] By distinguishing real anomalies from detector failures, the reliability of overall monitoring can be improved, the interference of false alarms on normal operations can be reduced, helping maintenance personnel to conduct equipment inspections and maintenance more effectively, and it can also effectively detect and respond to abnormal situations in the energy storage container, thereby improving the safety and efficiency of the overall system.

[0119] S207. Determine the warning location information and warning level according to the real-time monitoring data.

[0120] S208. Obtain the false alarm frequency of the detector that collected the abnormal data.

[0121] Among them, the false alarm frequency is used to indicate the frequency when it is determined that there is abnormal data in the real-time monitoring data, but the change parameter of the abnormal data is within the preset change limit range.

[0122] Exemplarily, the fire host will record and calculate the false alarm frequency of each detector for evaluating the reliability and accuracy of the detector. Therefore, the fire host can retrieve the data to obtain the false alarm frequency of the detector that collected the abnormal data.

[0123] S209. Judge whether the false alarm frequency is greater than the preset threshold.

[0124] If it is, execute step S210; if not, execute step S212.

[0125] Exemplarily, if the false alarm frequency is greater than the preset threshold, it indicates that the detector may have a high false alarm tendency; if the false alarm frequency is less than or equal to the preset threshold, it indicates that the detector basically has no false alarm tendency.

[0126] S210. Continue to obtain the real-time monitoring data for the target duration, and verify the warning location information and warning level according to the real-time monitoring data for the target duration.

[0127] Exemplarily, when the false alarm frequency is relatively high and greater than a preset threshold, the fire control host can continue to obtain real-time monitoring data within a target duration to further verify whether the previously determined early warning positioning information and early warning level are correct. Specifically, the real-time monitoring data within the target duration can be analyzed, and the same positioning determination method and level division method can be used to determine new early warning positioning information and early warning level, and it is judged whether they are the same as the previously determined early warning positioning information and early warning level. If they are the same, it indicates that the verification is passed; if they are different, it indicates that the previous early warning information may be a false alarm, and the fire control host can adjust the early warning positioning information and early warning level to avoid unnecessary response measures.

[0128] By considering the false alarm frequency, it is possible to more accurately judge abnormal situations and reduce the misguidance caused by false alarms; in addition, the verification step also ensures the accuracy of the early warning information, avoiding resource waste and unnecessary intervention caused by false alarms. Through the above method, not only can abnormal situations in the energy storage container be effectively detected and responded to, but also the overall fire safety and efficiency can be improved through the analysis of the false alarm frequency and the verification step.

[0129] If the verification is passed, directly execute S212; if the verification fails, first execute S211.

[0130] S211. Adjust the early warning positioning information and early warning level.

[0131] S212. Determine the battery pack with thermal runaway according to the early warning positioning information.

[0132] S213. Judge whether the early warning level reaches the target level.

[0133] If so, execute step S214; if not, execute step S215.

[0134] S214. Determine the direct fire-fighting equipment of the battery pack with thermal runaway as the target fire-fighting equipment.

[0135] S215. Determine the adjacent battery packs of the battery pack with thermal runaway according to the early warning positioning information, and determine that both the direct fire-fighting equipment of the battery pack with thermal runaway and the direct fire-fighting equipment of the adjacent battery packs are the target fire-fighting equipment.

[0136] S216. Control the target fire-fighting equipment.

[0137] It should be noted that the specific implementation of the above other steps can refer to the description of other embodiments and will not be elaborated here. In practical applications, when the fire control host executes the fire warning control method, it may include some or all of the above steps, and the embodiments of the present application do not make restrictions.
