[0002] With the development of technology, energy storage has become a key means of energy transformation and the construction of new power systems. Currently, battery-based energy storage is widely used in various fields. Compared with other conventional energy storage technologies, battery-based energy storage has advantages such as high energy density, fast response time, and flexible deployment. However, due to its inherent structural characteristics, battery-based energy storage currently poses significant safety risks. When a battery-based energy storage system catches fire, the fire spreads rapidly and is difficult to extinguish, posing a huge challenge to fire rescue efforts. Therefore, it is necessary to improve the fire protection design for energy storage power stations to address their unique fire risks and ensure their safe operation. However, current fire protection solutions for energy storage power stations suffer from low fire protection efficiency and poor fire suppression effectiveness.

[0046] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0047] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0048] Existing energy storage fire suppression systems primarily use heptafluoropropane and water as extinguishing agents. For battery system fire detection, there are only two modes: manual and automatic. In automatic mode, the system monitors relevant parameters of the battery system through sensors, such as temperature and smoke. When these parameters reach specific thresholds, the fire suppression mechanism is automatically triggered, releasing heptafluoropropane or spraying water to extinguish the fire. In manual mode, personnel rely on observing abnormal situations, such as seeing smoke or detecting an abnormal rise in temperature, to manually activate the fire suppression equipment.

[0049] The inventors of this application have discovered that existing fire suppression systems lack effective countermeasures before a fire occurs. Because there is no mechanism to isolate potentially problematic areas during the early warning phase, once a battery cabinet exhibits abnormalities such as increased temperature or smoke generation, it cannot be isolated from other parts in a timely manner. This allows the problem to spread rapidly to surrounding areas, leading to a rapid escalation of the fire or dangerous situation. Furthermore, current energy storage fire suppression systems rely entirely on sensors detecting a certain level of danger before initiating fire suppression, which may miss the optimal firefighting window, resulting in a more severe situation when the fire is finally extinguished, thus reducing firefighting efficiency and effectiveness.

[0050] Therefore, current fire protection solutions for energy storage power stations suffer from low fire protection efficiency and poor fire protection effectiveness.

[0051] In view of the above, this application provides a fire protection system, as follows:

[0052] Figure 1 A structural schematic diagram of a fire protection system provided in this application embodiment is shown below. Figure 1 As shown, the fire protection system includes: sensors, fire control devices, and fire-fighting equipment.

[0053] The sensor is used to detect the fire alarm monitoring indicators of the target energy storage cabinet and send an alarm signal to the fire control device when the fire alarm monitoring indicators are abnormal. The sensor can be located on the energy storage cabinet, for example, it can be pre-deployed inside the energy storage cabinet to monitor the environment inside the energy storage cabinet, thereby obtaining the fire alarm monitoring indicators corresponding to the environment inside the energy storage cabinet.

[0054] In one possible implementation, the sensor may include at least two of the following: a temperature sensor, a smoke sensor, a combustible gas sensor, and a volatile organic compound (VOC) sensor.

[0055] When the sensor includes a temperature sensor, it can be used to detect temperature indicators inside the target energy storage cabinet; when the sensor includes a smoke sensor, it can be used to detect smoke indicators (e.g., smoke content) inside the target energy storage cabinet; when the sensor includes a combustible gas sensor, it can be used to detect combustible gas indicators (e.g., combustible gas content) inside the target energy storage cabinet; when the sensor includes a VOC sensor, it can be used to detect VOC indicators (e.g., VOC content) inside the target energy storage cabinet. In other words, the fire alarm monitoring indicators for the target energy storage cabinet can include at least two of the following: temperature, smoke, combustible gas, and VOC.

[0056] Alternatively, multiple fire alarm monitoring indicators of the target energy storage cabinet can be detected using composite sensors.

[0057] Firefighting equipment is used to perform firefighting operations. This equipment may include, for example, one or more devices for fire alarm activation and devices for fire extinguishing. The fire alarm activation device may be, for example, an audible alarm or an optical alarm. The fire extinguishing device may include, for example, a device for discharging extinguishing media. In one possible implementation, when the firefighting equipment is for fire extinguishing, it may include a target gas device or a compressed air foam device.

[0058] Specifically, the target gas device includes target gas pipelines, target gas valves, and target gas nozzles. The target gas pipelines are connected to each energy storage cabinet and the target gas storage device. Each energy storage cabinet is equipped with a target gas valve and a target gas nozzle, used to control the opening of the target gas valve and release the target gas through the nozzle when the target gas device releases the target gas, thereby reducing the internal temperature of the energy storage cabinet or extinguishing a fire. Optionally, the target gas may be, for example, perfluorohexanone gas.

[0059] The compressed air foam device includes compressed air foam pipes, compressed air foam valves, and compressed air foam nozzles. The functions of each part of this compressed air foam device are similar to those of the parts of the target gas device, the only difference being that it sprays compressed air foam instead of the target gas, which will not be elaborated further here.

[0060] The fire control device is used to execute the fire control method provided in the embodiments of this application. The fire control device may be, for example, a fire control cabinet, a fire control host, a control chip, or other device with processing and control functions. Based on alarm signals received from sensors in the target energy storage cabinet, the fire control device controls the fire-fighting equipment to perform fire control on the target energy storage cabinet.

[0061] In one possible implementation, the fire protection system may further include an isolation indicator device for indicating which energy storage cabinets are in an isolated operating state. This isolation indicator device may be, for example, an isolation sign light, used to indicate which energy storage cabinet among multiple energy storage cabinets is currently in an isolated operating state. When the fire control device controls a target energy storage cabinet to enter an isolated operating state, the isolation indicator device indicates that the target energy storage cabinet is in an isolated operating state.

[0062] In one possible implementation, the fire protection system may further include a manual control device. This manual control device is used to respond to user operations and execute fire control corresponding to the user's operation. The manual control device is a device with manual control functionality, such as a manual control panel or control box. When the manual control device is a manual control panel, the manual control panel may include manual control buttons, or it may be a touchscreen panel with manual control components within its screen.

[0063] Staff can manually control the target energy storage cabinet to switch to isolated operation mode, and / or output fire alarm, and / or release target gas or compressed air foam, etc., by operating the manual control device.

[0064] For example, Figure 2 This is a structural schematic diagram of another fire protection system provided as an embodiment of this application. (See attached diagram.) Figure 2 As shown, the fire protection system is used for fire control of multiple energy storage cabinets. Each energy storage cabinet is a battery cabinet containing battery clusters composed of battery cells to achieve energy storage. In one embodiment, the battery cells in the battery cabinet may be, for example, manganese-based battery cells.

[0065] Each battery cabinet includes temperature sensors, smoke sensors, combustible gas sensors, VOC sensors, and composite sensors. The fire control device is a fire alarm control panel within the fire control cabinet, which includes the fire alarm control panel and a target gas storage device. The fire alarm control panel is used to output fire alarms. Taking perfluoroacetone (PFA) as an example, the target gas storage device can be a PFA cylinder.

[0066] The fire alarm control panel is connected to the compressed air foam system, which includes a water pump, a water tank, a foam generator, and a control panel. The compressed air foam system is used to control the water pump and foam generator to produce compressed air foam according to the control of the fire control device.

[0067] The multiple energy storage cabinets include a target gas device and a compressed air foam device. The cabinets are connected by target gas pipelines and compressed air foam pipelines. When the target gas needs to be released according to the fire control device, the target gas is delivered through the target gas pipeline, the corresponding target gas valve in the energy storage cabinet is opened, and the target gas is released through the corresponding target gas nozzle. When the compressed air foam needs to be released according to the fire control device, compressed air foam is delivered through the compressed air foam pipeline, the corresponding compressed air foam valve in the energy storage cabinet is opened, and the compressed air foam is released through the corresponding compressed air foam nozzle.

[0068] In addition, the fire protection system also includes a field control box (i.e., a manual control device), which allows staff to perform the corresponding fire control operations.

[0069] The fire protection system also includes isolation sign lights (i.e., isolation indicators) to indicate that the energy storage cabinet is in an isolated operating state.

[0070] The following is based on Figure 1 and Figure 2 Taking the fire protection system shown as an example, the method provided in this application will be described in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0071] The subject executing this method is the aforementioned Figure 1 The fire control device mentioned in the text.

[0072] Figure 3 A schematic diagram of a fire control process is provided as an embodiment of this application, such as... Figure 3 As shown, the method includes:

[0073] S301. When an alarm signal from at least one sensor of the target energy storage cabinet is obtained, the alarm level of the target energy storage cabinet is determined according to the type of alarm signal.

[0074] The sensor can determine whether to issue an alarm signal based on a preset threshold. For example, taking the aforementioned temperature sensor as an example, a preset temperature threshold can be set. When the temperature sensor detects that the temperature in the target energy storage cabinet is greater than or equal to the preset temperature threshold, it indicates that the temperature in the target energy storage cabinet is abnormal and there may be a fire risk. Therefore, an alarm signal can be sent to the fire control device.

[0075] The type of alarm signal can be determined based on either its type identifier or its source. For example, an alarm signal may include a type identifier, which determines its type. Specifically, a type identifier of 1 indicates a temperature alarm, while 2 indicates a smoke alarm. Alternatively, the type of alarm signal can be determined based on the sensor from which it originates. For instance, if the alarm signal originates from a temperature sensor, its type is a temperature alarm.

[0076] The alarm level of the target energy storage cabinet can be determined based on a single alarm signal type or a combination of multiple alarm signal types. For example, when the alarm level is determined based on a single alarm signal type, different alarm signal types may correspond to different alarm levels. Similarly, when the alarm level is determined based on a combination of multiple alarm signal types, different combinations of alarm signal types may correspond to different alarm levels. For instance, the alarm levels will differ depending on whether the alarm signals include signals from temperature and smoke sensors or signals from temperature, smoke, hazardous gas, and VOC sensors.

[0077] It should be understood that the alarm level can be set according to actual needs. For example, it can be set to three alarm levels to distinguish different fire risks of the target energy storage cabinet. This application does not limit the specific number of fire levels.

[0078] S302. Based on the alarm level, implement fire control for the target energy storage cabinet corresponding to the alarm level.

[0079] Different fire control settings can be configured for different alarm levels. Based on the determined alarm level, fire control corresponding to the alarm level is implemented on the target energy storage cabinet to perform fire-fighting operations, thereby improving the fire-fighting effectiveness of the energy storage cabinet.

[0080] One possible approach is to directly control the fire-fighting equipment to perform fire-fighting operations on the target energy storage cabinet according to the alarm level.

[0081] Another possible implementation is to send an alarm signal to the control device of the target energy storage cabinet according to the alarm level, so that the control device can perform fire control on the target energy storage cabinet corresponding to the alarm level. In this case, the control device can control the fire-fighting equipment corresponding to the target energy storage cabinet.

[0082] The fire control method provided in this application determines the alarm level of the target energy storage cabinet based on the type of alarm signal when an alarm signal from at least one sensor of the target energy storage cabinet is received. Based on the alarm level of the target energy storage cabinet, fire control corresponding to the alarm level is performed. This allows for multi-level fire control operations corresponding to multiple alarm levels based on one or more alarm signals from the target energy storage cabinet, enabling more precise and accurate fire control operations according to different situations of the target energy storage cabinet, thereby improving the fire-fighting efficiency and effectiveness of the energy storage power station.

[0083] In one possible implementation, the type of alarm signal can characterize the degree of harm to the target energy storage cabinet. Based on this degree of harm, the alarm level of the target energy storage cabinet is determined.

[0084] When only a single alarm signal exists, different alarm signal types indicate different levels of harm to the target energy storage cabinet. For example, when the alarm signal is from a temperature sensor, it only indicates that the temperature inside the target energy storage cabinet is high, posing a minor fire risk and a relatively low level of harm. However, when the alarm signal is from a hazardous gas sensor, it indicates that the concentration of hazardous gases inside the target energy storage cabinet is high, posing a significant fire risk and a relatively high level of harm.

[0085] When multiple alarm signals are present, different combinations of alarm signal types indicate different levels of hazard to the target energy storage cabinet. For example, when the alarm signals are from both temperature and smoke sensors, the alarm signal types are temperature alarm and smoke alarm, indicating that the target energy storage cabinet has a high temperature and high smoke content, posing a moderate fire risk and a moderate level of hazard. When the alarm signals include those from temperature, smoke, hazardous gas, and VOC sensors, it indicates that the target energy storage cabinet has a high temperature, and the levels of smoke, hazardous gases, and SOC are all high, posing a significant fire risk and a significant level of hazard.

[0086] The following example, using alarm signals from temperature sensors, smoke sensors, hazardous gas sensors, and VOC sensors, and alarm levels including the first alarm level, the second alarm level, and the third alarm level, will be used to introduce how to carry out fire control in a specific way.

[0087] First alarm level:

[0088] Figure 4 This is another schematic diagram of a fire control process provided in an embodiment of this application, such as... Figure 4 As shown, the method specifically includes:

[0089] S401. If the alarm signal is a temperature alarm signal from a temperature sensor or a smoke alarm signal from a smoke sensor, then the alarm level is determined to be the first alarm level.

[0090] Since the alarm signal is a temperature alarm signal from a temperature sensor or a smoke alarm signal from a smoke sensor, the anomaly in the target energy storage cabinet can only be characterized by an abnormal temperature or an abnormal smoke content.

[0091] When only temperature anomalies exist, these anomalies may be just beginning to appear. For example, in an energy storage cabinet, heat dissipation in a localized area might be slightly impeded, or a battery module might experience a small temperature rise due to a brief imbalance in charging and discharging. These initial temperature changes are often limited to a localized area and do not affect the core components of the entire energy storage cabinet or trigger a large-scale chain reaction.

[0092] If only abnormal smoke levels are detected, the source of the smoke may not be a serious problem in a critical part of the energy storage system. For example, it could be that the insulation material of some auxiliary lines has produced trace amounts of volatiles after long-term operation, or that a small amount of smoke has been produced by slight heating of the surface of a non-critical component. These situations usually do not directly affect the core functions of the energy storage cabinet, such as the charging and discharging performance of the batteries.

[0093] Therefore, when there is only an abnormal temperature or an abnormal smoke content inside the target energy storage cabinet, the degree of harm to the target energy storage cabinet is low, so the alarm level can be determined as the first alarm level corresponding to the low degree of harm.

[0094] S402. Based on the first alarm level, perform the first fire control corresponding to the first alarm level on the target energy storage cabinet, so as to output the first alarm signal, stop the operation of the target energy storage cabinet, and shut down at least one of the temperature regulation systems of the target energy storage cabinet.

[0095] The first alarm signal can be, for example, an audible alarm signal, a visual alarm signal, or another alarm signal, to indicate that the target energy storage cabinet is at the first alarm level. Alternatively, the content of the first alarm signal may differ from that of the other alarm signals. For example, the content of the first alarm signal may be "Energy storage cabinet 1 has reached the first alarm level, please handle it promptly." Similarly, the content of other alarm signals may be "Energy storage cabinet 1 has reached alarm level X, please handle it promptly," etc., to distinguish them.

[0096] When an anomaly occurs in the target energy storage cabinet and is identified as a first-level alarm (low-risk but anomaly already exists, such as abnormal temperature or abnormal smoke content only), shutting down the cabinet is to prevent the anomaly from escalating and triggering a chain reaction. For example, if the anomaly is due to a slight increase in the temperature of a battery module, continued operation may cause heat to be transferred to other battery modules, affecting more batteries and gradually escalating the problem from a localized minor anomaly into a serious issue for the entire energy storage cabinet.

[0097] If the alarm is a first-level alarm triggered by a temperature anomaly, shutting down the temperature control system helps troubleshoot whether the anomaly is due to a malfunction in the system itself or other causes. For example, a fan malfunction in the temperature control system might cause a localized temperature increase; shutting it down allows for individual inspection of the fan and related temperature control components to determine if the temperature anomaly is caused by a problem with those components. The temperature control system could be, for example, an air conditioning system.

[0098] Furthermore, continued operation of a faulty temperature control system may consume additional energy and pose potential hazards due to its abnormal operating conditions. For example, a malfunctioning electrical component in the temperature control system may generate electrical sparks, which increases the risk of fire in the presence of smoke or abnormal temperatures in the energy storage cabinet; shutting it down can eliminate this risk.

[0099] For example, a first alarm level can be sent to the Battery Container Parallel Controller (BCPC), which in turn sends a first alarm level to the Battery Cluster Management Unit (BECU). The BECU then shuts down the air conditioning of the target energy storage unit based on the first alarm level.

[0100] Second alarm level:

[0101] Figure 5 This is another schematic diagram of a fire control process provided in an embodiment of this application, such as... Figure 5 As shown, the method specifically includes:

[0102] S501. If the alarm signal includes a temperature alarm signal from a temperature sensor and a smoke alarm signal from a smoke sensor, then the alarm level is determined to be the second alarm level.

[0103] Since the alarm signals are temperature alarm signals from the temperature sensor and smoke alarm signals from the smoke sensor, the anomalies in the target energy storage cabinet include not only temperature anomalies but also smoke content anomalies.

[0104] When both temperature anomalies and smoke concentration anomalies exist simultaneously, these two anomalies can interact and accelerate the deterioration of the problem. For example, increased temperature may lead to more evaporation of substances, thereby increasing smoke production; conversely, the presence of smoke may affect heat dissipation efficiency, further contributing to temperature increases. This mutually reinforcing relationship makes the problem no longer as simple as either temperature anomaly or smoke anomaly alone, but rather more complex and difficult to control.

[0105] Therefore, when there are abnormal temperatures and abnormal smoke levels inside the target energy storage cabinet, the degree of harm to the target energy storage cabinet is moderate, so the alarm level can be determined as the second alarm level corresponding to the moderate degree of harm.

[0106] S502. Based on the second alarm level, implement the second fire control corresponding to the second alarm level on the target energy storage cabinet to switch the target energy storage cabinet to the isolated operation state and cause the target gas to be released inside the target energy storage cabinet.

[0107] When a target energy storage unit reaches the second alarm level, abnormal temperature and smoke levels are detected inside. In this situation, switching it to isolation operation mode is to prevent the abnormality from spreading to other energy storage units or surrounding equipment. Energy storage systems typically consist of multiple energy storage units that are electrically and physically interconnected. An abnormal temperature and smoke level in one energy storage unit can affect adjacent units through heat conduction, airflow, or electrical wiring. For example, high temperatures may raise the ambient air temperature, affecting the heat dissipation environment of nearby energy storage units; smoke may contain corrosive substances that, if spread, can damage other equipment. Isolation operation cuts off this potential transmission path, confining the hazard to the interior of the target energy storage unit.

[0108] For details regarding the specifics of the isolated operation status, please refer to the description in the subsequent embodiments; they will not be elaborated upon here.

[0109] In cases where the target energy storage cabinet exhibits abnormal temperature and smoke levels, releasing a target gas can help suppress the further development of the abnormal situation. The target gas can have multiple functions, including fire extinguishing, cooling, and inhibiting chemical reactions. For example, the target gas could be perfluoroacetone, which can directly extinguish a fire or lower the temperature inside the energy storage cabinet. Alternatively, a target gas that can inhibit potential chemical reactions caused by smoke can prevent further smoke accumulation or prevent the smoke from triggering more severe chemical changes.

[0110] Optionally, step S502 may also include implementing at least one of the following according to the second fire control: outputting a second alarm signal, stopping the operation of the target energy storage cabinet, shutting down the temperature regulation system of the target energy storage cabinet, and shutting down the air exchange system of the target energy storage cabinet.

[0111] The second alarm signal is a different alarm signal from the first alarm signal. For example, when the first alarm signal is one of the following: an audible alarm signal, a visual alarm signal, etc., the second alarm signal can be both an audible alarm signal and a visual alarm signal to indicate that the target energy storage cabinet is at the second alarm level and to distinguish it from the first alarm signal. Alternatively, the content of the second alarm signal may differ from that of the first alarm signal, for example, the content of the second alarm signal may be "Energy storage cabinet 1 has reached the second alarm level, please handle it promptly," to distinguish it from the first alarm signal, etc.

[0112] Shutting down the air exchange system of the target energy storage cabinet can prevent abnormal temperatures and smoke levels in the target energy storage cabinet from affecting the air exchange system, thus avoiding impacts on the temperature and smoke levels of other energy storage cabinets, or preventing abnormal temperatures and smoke levels in the space where the target energy storage cabinet is stored, thereby reducing the fire risk caused by the abnormalities.

[0113] Regarding stopping the operation of the target energy storage cabinet and shutting down its temperature control system, as mentioned above... Figure 4 The corresponding content is the same, so it will not be repeated here.

[0114] For example, a second alarm level can be sent to the BCPC, which in turn sends a second alarm level to the BECU, which then shuts down the air conditioning and ventilation system (i.e., air exchange system) of the target energy storage cabinet based on the second alarm level.

[0115] Third alarm level:

[0116] Figure 6 This is a schematic diagram of another fire control process provided in an embodiment of this application, such as... Figure 6 As shown, the method specifically includes:

[0117] S601. If the alarm signal includes a temperature alarm signal from a temperature sensor, a smoke alarm signal from a smoke sensor, a combustible gas alarm signal from a combustible gas sensor, and a VOC alarm signal from a VOC sensor, then the alarm level is determined to be the third alarm level.

[0118] Since the alarm signals include temperature alarm signals from temperature sensors, smoke alarm signals from smoke sensors, combustible gas alarm signals from combustible gas sensors, and VOC alarm signals from VOC sensors, the anomalies in the target energy storage cabinet can be characterized not only by abnormal temperature and smoke content, but also by abnormal combustible gas content and VOC content.

[0119] When abnormal temperatures, smoke levels, combustible gas levels, and VOC levels are observed, it indicates that the problem within the energy storage cabinet involves multiple aspects. It is no longer merely a localized, single-type anomaly, but rather a potentially comprehensive failure or hazardous condition across the entire system. For example, the presence of combustible gases and VOCs may signify damage to the battery's internal sealing structure, with electrolyte or other chemicals leaking and reacting—a serious anomaly.

[0120] Therefore, when there are abnormalities in temperature, smoke content, combustible gas content, and VOC content in the target energy storage cabinet, the degree of harm to the target energy storage cabinet is relatively high. Thus, the alarm level can be determined as the third alarm level corresponding to the relatively high degree of harm.

[0121] S602. Based on the third alarm level, implement the third fire control corresponding to the third alarm level on the target energy storage cabinet so that compressed air foam is sprayed inside the target energy storage cabinet.

[0122] Compressed air foam is a unique fire extinguishing medium that can effectively extinguish manganese-based lithium-ion battery fires, provide excellent thermal insulation, prevent heat spread, and prevent reignition. It boasts higher fire extinguishing efficiency, thus enhancing overall fire suppression effectiveness. Furthermore, compressed air foam is highly biodegradable, improving the environmental friendliness of firefighting efforts.

[0123] When a third-level alarm occurs, it usually corresponds to a more serious fire risk. Therefore, it is necessary to spray compressed air foam inside the target energy storage cabinet to shorten the fire extinguishing time through its high fire extinguishing efficiency, reduce the losses inside the energy storage cabinet caused by the fire risk, and improve fire extinguishing efficiency.

[0124] Optionally, step S602 may also include implementing at least one of the following according to the third fire control: outputting a third alarm signal, stopping the operation of the target energy storage cabinet, shutting down the temperature control system of the target energy storage cabinet, and shutting down the air exchange system of the target energy storage cabinet.

[0125] The third alarm signal differs from both the first and second alarm signals, but its implementation is similar to that of the first and second alarm signals, and will not be elaborated further here. For stopping the operation of the target energy storage cabinet, shutting down its temperature control system, and shutting down its air exchange system, please refer to the descriptions of these three items in the preceding embodiments, and will not be repeated here.

[0126] For example, a third alarm level can be sent to the BCPC, which in turn sends a third alarm level to the BECU, which then shuts down the air conditioning and ventilation system (i.e., air exchange system) of the target energy storage cabinet based on the third alarm level.

[0127] It should be understood that the above is only an example of a three-level alarm level. This application is not limited to a three-level alarm level. The number of alarm levels and the fire control content corresponding to each alarm level can be flexibly combined according to actual needs.

[0128] The method provided in this application, upon receiving an alarm signal from at least one sensor of a target energy storage cabinet, determines the alarm level corresponding to the type of alarm signal from a three-level alarm system. Based on the alarm level, fire control is applied to the target energy storage cabinet according to that alarm level. This allows for three-level fire-fighting operations corresponding to the three alarm levels, based on one or more alarm signals from the target energy storage cabinet. This more precise fire-fighting operations are performed according to different situations of the target energy storage cabinet, thereby improving the fire-fighting efficiency and effectiveness of the energy storage power station.

[0129] The following section provides a detailed explanation of the isolated operation state, specifically the step S502 mentioned above, which involves switching the target energy storage cabinet to isolated operation. When the target energy storage cabinet is in isolated operation, isolated fire control can be implemented through the following steps.

[0130] Figure 7 This is a schematic diagram of another fire control process provided in an embodiment of this application, such as... Figure 7 As shown, the method may further include:

[0131] S701. Obtain the fire early warning monitoring indicators of the target energy storage cabinet.

[0132] Among them, fire early warning monitoring indicators may include at least one of temperature, battery state of charge (SOC), smoke content, and VOC content.

[0133] The temperature, smoke content, and VOC content can be obtained, for example, through the aforementioned sensors or through other devices capable of acquiring the corresponding fire warning monitoring indicators; this application does not impose any restrictions on this. SOC can be obtained, for example, through a battery management system (BMS) connected to the target energy storage cabinet.

[0134] By monitoring the fire alarm indicators of the target energy storage cabinet in real time, we can obtain the real-time fire alarm indicators of the target energy storage cabinet.

[0135] S702. Determine the isolation level of the target energy storage cabinet based on fire early warning monitoring indicators.

[0136] Based on the real-time fire warning monitoring indicators of the target energy storage cabinet, it can be determined whether there are fire warning monitoring indicators that exceed the preset limits. If there are fire warning monitoring indicators that exceed the preset limits, the isolation level of the target energy storage cabinet can be determined based on the fire warning monitoring indicators that exceed the preset limits.

[0137] When the fire alarm monitoring indicators include only one indicator, the isolation level of the target energy storage cabinet can be determined based on whether that indicator exceeds a preset limit. For example, if the fire alarm monitoring indicators only include temperature, and the temperature is greater than or equal to a first temperature threshold, the isolation level corresponding to the target energy storage cabinet can be determined.

[0138] When the fire early warning monitoring indicators include multiple indicators, the isolation level of the target energy storage cabinet can be determined by comparing the values ​​of the multiple indicators with the preset limits.

[0139] For example, suppose the fire alarm monitoring indicators include temperature and SOC. If the temperature is greater than or equal to a first temperature threshold and the SOC is greater than or equal to a preset SOC threshold, then the isolation level of the target energy storage cabinet is determined to be the first isolation level. The first temperature threshold and SOC threshold can be set according to actual needs; for example, the first temperature threshold could be 65℃, and the SOC threshold could be 25%, etc.

[0140] Assume that the fire alarm monitoring indicators include temperature, smoke concentration, and VOC content. If the temperature is greater than or equal to a second temperature threshold, the smoke concentration is greater than or equal to a preset smoke threshold, and the VOC content is greater than or equal to a preset VOC threshold, then the isolation level of the target energy storage cabinet is determined to be the second isolation level. The first and second temperature thresholds can be the same or different. These second temperature thresholds, preset smoke thresholds, and preset VOC thresholds can be set according to actual needs; for example, the second temperature threshold could be 80℃, the preset smoke threshold could be 0.3 dB / m³, and the preset VOC threshold could be 200 ppm, etc.

[0141] S703. Based on the isolation level, implement the isolation fire control corresponding to the isolation level.

[0142] Different isolation levels can be configured with different fire control systems. For example, for lower isolation levels, simpler or more energy-efficient fire control systems can be implemented to achieve isolation while conserving fire-fighting resources. For higher isolation levels, more efficient and effective fire control systems can be implemented to improve the isolation effect of the target energy storage cabinet.

[0143] Among them, the isolation fire control may include one or more of the following: controlling the release of target gas in the target energy storage cabinet, monitoring the fire early warning monitoring indicators of the target energy storage cabinet, monitoring the fire early warning monitoring indicators of adjacent energy storage cabinets of the target energy storage cabinet, and controlling the release of target gas in the target energy storage cabinet and / or adjacent energy storage cabinets of the target energy storage cabinet.

[0144] Specifically, the number of isolation levels can be set according to actual needs; for example, it can be set to two isolation levels, including a first isolation level and a second isolation level. This application does not limit the number of isolation levels or the specific content of the isolation fire control for each isolation level.

[0145] For example, continuing with the example in step S701 above, assume that the fire alarm monitoring indicators include temperature and SOC. If the temperature is greater than or equal to a first temperature threshold and the SOC is greater than or equal to a preset SOC threshold, then the isolation level of the target energy storage cabinet is determined to be the first isolation level. Based on the first isolation level, the target gas is controlled to be released into the target energy storage cabinet, and the fire alarm monitoring indicators of the adjacent energy storage cabinets are monitored.

[0146] By controlling the release of target gas within the target energy storage cabinet, the cabinet is cooled and insulated, reducing its impact on other energy storage cabinets. Since the target energy storage cabinet operates in isolation, it indicates a fire hazard, which may trigger a fire hazard in adjacent cabinets. Therefore, fire warning indicators of adjacent energy storage cabinets can be monitored to detect and warn of potential fire cascading effects.

[0147] Optionally, if there are abnormal fire warning monitoring indicators when monitoring the fire warning monitoring indicators of adjacent energy storage cabinets of the target energy storage cabinet, the isolation level of the adjacent energy storage cabinets can be determined based on the fire warning monitoring indicators of the adjacent energy storage cabinets, so as to switch the adjacent energy storage cabinets to the isolated operation state.

[0148] For example, continuing with the example in step S701 above, assume that the fire alarm monitoring indicators include temperature, smoke content, and VOC content. If the temperature is greater than or equal to a second temperature threshold, the smoke content is greater than or equal to a preset smoke threshold, and the VOC content is greater than or equal to a preset VOC threshold, then the isolation level of the target energy storage cabinet is determined to be the second isolation level. Based on the second isolation level, the target gas is controlled to be released into the target energy storage cabinet and / or into adjacent energy storage cabinets, and the fire alarm monitoring indicators of the target energy storage cabinet and / or the execution status of the isolation fire control are output.

[0149] By controlling the release of target gas into the target energy storage cabinet and / or adjacent energy storage cabinets, the target energy storage cabinet and / or adjacent energy storage cabinets are cooled and insulated, thereby reducing the impact of the target energy storage cabinet on other energy storage cabinets.

[0150] The fire alarm monitoring indicators and / or the execution status of isolation fire control of the target energy storage cabinet can be output to systems such as the back-end management system and enterprise management system, or to the electronic devices of staff, to record the fire alarm monitoring indicators and / or the execution status of isolation fire control of the target energy storage cabinet, facilitating the recording and retrospective analysis of any fire incidents that occur. For example, the output can be sent to an Energy Management System (EMS).

[0151] Optionally, after switching the target energy storage cabinet to isolated operation mode, an isolation indicator device can be used to indicate that the target energy storage cabinet is in isolated operation mode. Optionally, the isolation level of the target energy storage cabinet can also be indicated by the isolation indicator device.

[0152] The method provided in this application embodiment obtains the fire warning monitoring indicators of the target energy storage cabinet, determines the isolation level of the target energy storage cabinet based on the fire warning monitoring indicators, and executes the isolation fire control corresponding to the isolation level to switch the target energy storage cabinet with fire risk to an isolated operation state, thereby reducing the impact of the target energy storage cabinet on other energy storage cabinets. This reduces the problem of increased fire risk in other energy storage cabinets due to the impact of the target energy storage cabinet with fire risk, and further improves fire efficiency and safety.

[0153] In one possible implementation, fire control can also be performed in response to manual operation by staff. Specifically, it can respond to user operation and execute fire control corresponding to the user's operation. Staff can manually control and execute one or more preset fire controls by operating a manual control device. This manual control device can be, for example, the aforementioned... Figure 1 The manual control panel, control box, etc. mentioned in the text.

[0154] In this implementation, the user's operation of the corresponding fire control may include at least one of the following: controlling the release of extinguishing media inside the target energy storage cabinet, or switching the target energy storage cabinet to an isolated operation state. The extinguishing media may include at least one of the following: target gas (e.g., perfluoroacetone gas), extinguishing dry powder, compressed air foam, etc.

[0155] Specifically, staff can manually control the release of extinguishing agents from the target energy storage cabinet and switch the cabinet to an isolated operating state. When the target energy storage cabinet is switched to an isolated operating state in response to a user's operation, this isolated operating state is similar to the aforementioned... Figure 7 The isolated operation status mentioned above is the same, so it will not be repeated here.

[0156] The method provided in this application embodiment, in addition to enabling fire control of the energy storage cabinet through the aforementioned automatic fire control method, can also trigger fire control through manual operation as described in this embodiment. When a user's manual operation is received, the method responds to the user's operation and executes the corresponding fire control, providing the user with a more flexible fire control method and thus improving the flexibility of fire control.
