[0028] Next, the fire control method for the energy storage system provided by the embodiments of the present application is introduced.

[0029] In the embodiments of the fire control method for the energy storage system, the fire control system for the energy storage system is used as an execution subject. In order to simplify and facilitate the description, the execution subject will be omitted in the subsequent method embodiments. The method comprises the following steps: obtaining abnormal detection data of the energy storage system; determining the fire alarm level and the fire alarm source of the energy storage system based on the abnormal detection data; determining the target fire control strategy for the energy storage system based on the fire alarm level and the fire alarm source; and controlling and processing the energy storage system by fire using the target fire control strategy.

[0030] The fire control method for the energy storage system provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings. Although the method operations provided in the embodiments or shown in the drawings are described below, more or fewer operations can be included in the method based on conventional or non-creative labor. The execution order of the steps is not limited to the execution order provided in the embodiments of the present application in steps that do not have necessary causal relationships in logic. The method can be executed in sequence or in parallel (for example, in a parallel processor or a multi-threaded processing environment) when the object processing process in the actual method or the device is executed.

[0031] Please refer to FIG. 2, which is a flowchart of one embodiment of the fire control method for the energy storage system provided by the embodiments of the present application. The fire control method for the energy storage system comprises steps 201-203:

[0032] 201, obtaining abnormal detection data of the energy storage system.

[0033] The abnormality detection data can include abnormality detection data collected by the battery management system and / or the fire detection module.

[0034] In this embodiment, the battery management system can detect the voltage and temperature of each battery cell of the energy storage system, and estimate the battery state information such as SOC (State of Charge) and SOH (State of Health) in real time. If the battery state information is abnormal, corresponding abnormality detection data is generated.

[0035] In this embodiment, the fire detection module can include package-level detection devices, cluster-level detection devices, and system-level detection devices.

[0036] The system-level detection devices can include system-level temperature detectors, system-level smoke detectors, and system-level combustible gas detectors.

[0037] Optionally, the number of system-level detectors can be adapted according to the size of the system space, and each type of detector can be arranged in 1-3.

[0038] It should be noted that the system-level detectors are also in working state when the energy storage system is in normal operation, and the detection frequency can be set according to actual needs.

[0039] The cluster-level detection devices can include cluster-level temperature detectors, cluster-level smoke detectors, and cluster-level combustible gas detectors, and one set is arranged for each cluster of batteries. The protection area covers the range of the battery cluster where the detection device is located. The cluster-level detectors are in standby state when the energy storage system is in normal operation, and are in working state when the corresponding fire alarm signal is triggered.

[0040] The package-level detection devices can include package-level temperature detectors, package-level smoke detectors, and package-level combustible gas detectors.

[0041] Optionally, the number of package-level detectors can be adapted to the number of battery packages included in the energy storage system, for example, one set of package-level detectors (at least one of the package-level temperature detectors, the package-level smoke detectors, and the package-level combustible gas detectors) is adapted for each battery package.

[0042] It should be noted that the package-level detectors are in standby state when the energy storage system is in normal operation, and are in working state when the corresponding fire alarm signal is triggered.

[0043] It should be noted that the abnormality detection data in step 201 is obtained by the system-level detection device in the fire detection module, because among the package-level detection device, the cluster-level detection device and the system-level detection device in the fire detection module, only the system-level detection device is in working state when the energy storage system is normally running, and the package-level and cluster-level detection devices are activated only when the corresponding fire abnormality of the energy storage system occurs, so that the comprehensive monitoring of the battery management system and the system-level detection device can be ensured, and energy can be saved.

[0044] 202. Based on the abnormality detection data, determine the fire alarm level and the fire alarm source of the energy storage system.

[0045] In this embodiment, the fire alarm source can include the battery management system and the system-level detection device. Specifically, the abnormality detection data can be identified, that is, it is identified that the abnormality detection data is from the battery management system and / or the system-level detection device.

[0046] In some embodiments, based on the abnormality detection data, the step of determining the fire alarm level of the energy storage system can include: obtaining the type quantity of different parameters in the abnormality detection data; obtaining the abnormality degree of the abnormality detection data; based on the type quantity and the abnormality degree, determining the fire alarm level of the energy storage system.

[0047] As described above, the system-level detection device can include a plurality of different types of detectors, such as a system-level temperature detector, a system-level smoke detector, a system-level flammable gas detector, etc. Therefore, the abnormality detection data can include the type quantity of at least one detection parameter. For example, when the system-level temperature detector, the system-level smoke detector and the system-level flammable gas detector are provided, the abnormality detection data can include the type quantity of one abnormal temperature parameter obtained by the system-level temperature detector, or the type quantity of any two parameters obtained by any two of the three system-level detection devices, or the type quantity of three parameters obtained by all the three system-level detection devices.

[0048] In some embodiments, the abnormality degree can include a pre-warning degree and an alarm degree.

[0049] In this embodiment, the abnormality degree is divided into two different degrees, one is a pre-warning degree and the other is an alarm degree. Obviously, the pre-warning degree is relatively light, which can be understood as not having a substantial fire, and the alarm degree is relatively heavy, which can be understood as having a substantial fire.

[0050] The step of obtaining the abnormality degree of the abnormality detection data comprises: comparing the abnormality detection value of the abnormality detection data with the preset warning threshold and the preset alarm threshold respectively; if the abnormality detection value is greater than or equal to the warning threshold and less than the alarm threshold, determining that the abnormality degree of the abnormality detection data is a warning degree; and if the abnormality detection value is greater than or equal to the alarm threshold, determining that the abnormality degree of the abnormality detection data is an alarm degree.

[0051] In some embodiments, the fire alarm levels can include a first fire alarm, a second fire alarm, and a third fire alarm, wherein the first to third fire alarms correspond to low to high emergency levels, respectively.

[0052] The step of determining the fire alarm level of the energy storage system based on the type quantity and the abnormality degree comprises: if the type quantity is one and the abnormality degree is a warning degree, determining that the fire alarm level of the energy storage system is a first fire alarm; if the type quantity is one and the abnormality degree is an alarm degree, or the type quantity is at least two and the abnormality degree is a warning degree, determining that the fire alarm level of the energy storage system is a second fire alarm; and if the type quantity is at least two and the abnormality degree is an alarm degree, determining that the fire alarm level of the energy storage system is a third fire alarm.

[0053] 203、Based on the fire alarm level and the fire alarm source, a target fire control strategy for the energy storage system is determined, and the energy storage system is controlled and processed by using the target fire control strategy.

[0054] In some embodiments, the target fire control strategy includes a first fire control strategy, a second fire control strategy, and a third fire control strategy, wherein the first fire control strategy corresponds to the first fire alarm, the second fire control strategy corresponds to the second fire alarm, and the third fire control strategy corresponds to the third fire alarm.

[0055] It should be noted that the level of the fire alarm is not constant, and the level of the fire alarm can change according to the actual fire control process. For example, with the intervention of fire control, the fire situation can be relieved and improved, or the fire situation can become more serious without improvement.

[0056] On the other hand, the level of the fire alarm at the beginning is not fixed but random, and can be a first fire alarm, a second fire alarm, or a third fire alarm.

[0057] The target fire-fighting strategy for the energy storage system is determined based on the fire alarm level and the fire alarm source, and the step of performing fire-fighting control processing on the energy storage system by using the target fire-fighting strategy includes: if the fire alarm source is the battery management system and / or the system-level detection device and the fire alarm level is a first-level fire alarm, a first fire-fighting strategy is selected as the target fire-fighting strategy, and the energy storage system is controlled and processed by using the first fire-fighting strategy; if the fire alarm source is the battery management system and / or the system-level detection device and the fire alarm level is a second-level fire alarm, a second fire-fighting strategy is selected as the target fire-fighting strategy, and the energy storage system is controlled and processed by using the second fire-fighting strategy; if the fire alarm source is the battery management system and / or the system-level detection device and the fire alarm level is a third-level fire alarm, a third fire-fighting strategy is selected as the target fire-fighting strategy, and the energy storage system is controlled and processed by using the third fire-fighting strategy.

[0058] In some embodiments, the step of performing fire-fighting control processing on the energy storage system by using the first fire-fighting strategy includes: executing the first fire-fighting strategy to control and process the energy storage system.

[0059] The method further includes: activating the pack-level detection device during execution of the first fire-fighting strategy; and if the pack-level detection device detects pack-level abnormal detection data of a pre-alarm degree within a preset time period, upgrading the first fire-fighting strategy to the second fire-fighting strategy.

[0060] The execution of the first fire-fighting strategy includes: obtaining first abnormal record data of the energy storage system, the first abnormal record data including first abnormal position information and a first abnormal value corresponding to an abnormal battery cell; determining the abnormal battery cell according to the first abnormal position information; adjusting an operating parameter of the abnormal battery cell based on the first abnormal value and a preset self-recovery adjustment strategy; and repeatedly performing abnormal monitoring and self-recovery adjustment on the abnormal battery cell until the abnormal battery cell returns to normal.

[0061] In this embodiment, the first fire-fighting strategy is used to deal with a first-level fire alarm, the abnormal battery cell is adjusted for self-recovery, and the abnormal battery cell is repeatedly monitored and adjusted for self-recovery until the abnormal battery cell returns to normal, which can avoid directly performing fire-fighting on the entire energy storage system, thereby reducing the damage to other normal battery cells and battery cells that have not yet experienced a substantial fire in the energy storage system, and reducing costs.

[0062] In a specific embodiment, 1) the battery management system (detecting parameters including battery voltage, temperature, temperature difference, SOC, SOH, etc.) detects that a single parameter reaches the early warning threshold, the signal is transmitted to the fire control system, triggering a first level of fire alarm, outputting the location, time, abnormal value, etc. Information of abnormal points to the local monitoring system (connected with the fire control system) and the cloud management system and records, and implements the first fire fighting strategy: the battery management system identifies the abnormal parameters of the battery cell and performs intelligent self-healing action (adjusts the voltage, temperature, SOC, etc. Parameters of abnormal battery through battery management technology of battery management system), while activating all package level detection devices (package level detection devices are in standby state when the system is normally operating); 2) after the first fire fighting strategy is started, it is judged whether the package level detection device detects the early warning signal corresponding to the early warning threshold within the preset time T, if not, it is judged whether there are still abnormal parameters identified by the battery management system after the self-healing action of the battery management system, if not, the fire fighting system returns to normal state, otherwise, the self-healing action of the battery management system continues, and it is judged whether the package level detection device detects the early warning signal and whether there are still abnormal parameters identified by the battery management system, and the cycle is continued until the battery management system does not identify any abnormal parameters, and the fire fighting system returns to normal state; 3) if the package level detection device detects the existence of early warning signal within the preset time T after the first fire fighting strategy is started, the fire control system activates the second level of fire alarm, outputs the location, time, abnormal value, etc. Information of abnormal points to the scene and cloud and records, and implements the second level of fire alarm protection action: EMS makes strategy adjustment, reduces the power of energy storage battery system to reduce the heat, enhances the working power of thermal management system (connected with battery management system), increases the heat dissipation and cooling effort, and the battery management system control circuit (control module in battery management system) disconnects the bypass of abnormal battery; 4) after the second level of fire alarm protection action is started, it is continued to judge whether the package level detection device detects the existence of alarm signal corresponding to the alarm threshold within the preset time T, if not, it is continued to judge whether the package level detection device detects the early warning signal within the preset time T, if yes, the second level of fire alarm is continued to maintain and the cycle is continued, if there is no early warning signal, it is continued to judge whether there are still abnormal parameters identified by the battery management system after the self-healing action of the battery management system, if not, the fire fighting system returns to normal state, otherwise, the self-healing action of the battery management system continues, and it is continued to judge whether the package level detection device detects the early warning signal and whether there are still abnormal parameters identified by the battery management system, and the cycle is continued until the battery management system does not identify any abnormal parameters, and the fire fighting system returns to normal state;5) After the secondary fire protection action is started, if the package level detection device detects an alarm signal within the preset time T, the fire control system triggers the tertiary fire alarm level, outputs the location, time, abnormal value and other information of the abnormal point to the scene and cloud, records, and implements the tertiary fire protection action: the sound and light alarm is started, the package level fire extinguishing device is started, the fire extinguishing agent is sprayed in the battery package where the abnormal signal occurs, and the cluster level detection device is started. If the fire spreads outside the battery package, the cluster level or system level detection device detects the fire signal, the fire gas release indicator light is on, warning personnel to prohibit entering or approaching, and after a delay of 30s, the system level fire extinguishing device is started for fire extinguishing operation; after the tertiary fire protection action is started, if the fire is controlled, the fire control system returns to normal state, if the fire is still not controlled, the emergency protection action of the fire control system is activated: the water fire control action is started, the water spray or water flooding is used for fire extinguishing operation, and the explosion venting panel, explosion-proof fan and other explosion-proof devices are opened for pressure relief when the pressure in the system cabin is too high to prevent explosion.
