[0069] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended for the purpose of interpretation of the present application and are not limiting of the present application. In addition, only parts related to the present application are shown in the accompanying drawings for the purpose of description.

[0070] Embodiment One

[0071] Fig. 1 is a flow chart of a method for extinguishing fire in a power storage station according to an embodiment. Referring to Fig. 1, the method for extinguishing fire in a power storage station comprises:

[0072] S101. Obtain battery pack internal abnormality detection information of each battery pack, and battery pack coding information of each battery pack.

[0073] In the present solution, the battery pack is arranged in the power storage station. The battery pack can be arranged in groups in the form of a battery cluster. Multiple battery clusters can be arranged in the power storage station.

[0074] In the present solution, the power storage station can be used in scenarios such as power generation side energy storage, power grid side energy storage, user side energy storage, and vehicle battery swap station.

[0075] In scenarios such as power generation side energy storage and power grid side energy storage, the power storage station can store excess power during low power consumption periods and release the power during power consumption peaks, thereby balancing the load of the power grid and relieving the power supply pressure during peak periods.

[0076] In scenarios such as battery swap stations, energy storage power stations can store excess power during low-usage periods and release the stored power during peak usage periods to meet the power demand of the battery swap station, reduce the power supply pressure of the power grid, and avoid power grid instability or failure caused by excessive power load.

[0077] When the power supply capacity of the power grid in the area where the battery swap station is located is insufficient to meet the peak power demand of the battery swap service, the energy storage power station can act as a backup power source to provide power in a timely manner to ensure the normal operation of the battery swap service and avoid affecting the normal use of new energy vehicles due to power shortages.

[0078] The energy storage power station has the ability to quickly charge and discharge, can charge a large number of batteries in a short time, shorten the charging time of the batteries, improve the efficiency and frequency of battery swapping, and can also adjust and optimize the output power to provide stable voltage and current for the batteries, prolong the service life of the batteries, and reduce the maintenance cost of the batteries.

[0079] In this scheme, the type of the battery pack is not limited, and the battery pack can be a lithium ion battery, a lead-acid battery, a nickel-hydrogen battery, etc.

[0080] In this scheme, the battery pack code information can be a data code (such as American Standard Code for Information Interchange (ASCII) code, Unicode code, etc.), and one battery pack code information is configured for one battery pack, and the battery pack code information corresponding to different battery packs is different.

[0081] In this scheme, the battery pack internal abnormality detection information is set to contain a specified type of physical measurement quantity, wherein the physical measurement quantity represents a physical quantity (such as temperature, particulate matter concentration, etc.) that can be directly measured by a sensor.

[0082] In this scheme, the type of physical measurement quantity contained in the battery pack internal abnormality detection information is not limited, and the selected physical measurement quantity is used to determine whether the battery pack has an abnormality (thermal runaway), and the specific type can be set according to design requirements.

[0083] For example, in this scheme, according to the physical measurement quantity corresponding to the battery pack internal abnormality detection information, one or a group of sensors can be designed for one battery pack, and the physical quantity of the corresponding battery pack is measured and obtained through the sensors configured for each battery pack, and then the battery pack internal abnormality detection information of the battery pack is formed.

[0084] Each sensor corresponding to each battery pack can be configured with a unique identification code, which can be a data code, and the identification code is configured to distinguish the sensors corresponding to different battery packs.

[0085] Exemplarily, in the present solution, the battery pack can be configured with a battery management system (BMS), and the battery pack code information can be pre-stored in the BMS of the battery pack. Accordingly, when the battery pack code information is needed, the battery pack code information can be read from the BMS of the battery pack.

[0086] Exemplarily, in the present solution, the battery pack code information can also be set as the identification code of the sensor corresponding to each battery pack, and the sensor outputs the measurement information while outputting the identification code of the sensor itself, that is, the output of the battery pack code information is realized.

[0087] S102. Determine whether the battery pack internal abnormality detection information matches the battery pack thermal runaway suppression trigger condition; when the battery pack internal abnormality detection information matches the battery pack thermal runaway suppression trigger condition, it is determined that there is at least one abnormal battery pack, and a first valve control instruction is generated.

[0088] In the present solution, the abnormal battery pack is defined as the battery pack when the battery pack internal abnormality detection information matches the battery pack thermal runaway suppression trigger condition.

[0089] Exemplarily, in the present solution, when the physical measurement quantity contained in the battery pack internal abnormality detection information is in a specified numerical interval, it is considered that the battery pack internal abnormality detection information matches the battery pack thermal runaway suppression trigger condition, and when the physical measurement quantity contained in the battery pack internal abnormality detection information is not in the specified numerical interval, it can be considered that the battery pack internal abnormality detection information does not match the battery pack thermal runaway suppression trigger condition.

[0090] Wherein, the numerical interval corresponding to each physical measurement quantity can be determined according to test data or simulation data, and the numerical interval should meet the condition that when the battery pack internal abnormality detection information matches the battery pack thermal runaway suppression trigger condition, the battery pack has or is about to have a thermal runaway failure.

[0091] Exemplarily, in the present solution, the thermal runaway failure is a phenomenon that when the temperature of the battery in the battery pack is high to a certain extent, a series of chemical reactions occur, resulting in rapid rise of the battery temperature and uncontrollable phenomenon.

[0092] S103. According to the battery pack code information corresponding to the abnormal battery pack, a second valve control instruction is generated.

[0093] S104. The first valve is controlled to act multiple times by the first valve control instruction to spray the thermal runaway suppression agent to the area to which the abnormal battery pack belongs multiple times.

[0094] In the present solution, the number of actions of the first valve can be determined according to simulation test, and the number of actions of the first valve can be a fixed value. The purpose of multiple actions of the first valve is to ensure the durability of the fire extinguishing effect and to avoid waste of the thermal runaway suppression agent.

[0095] The number of actions of the first valve can also be a dynamic value. Based on the abnormal detection information in the battery pack, the stage or level of thermal runaway of the abnormal battery pack can be determined, and the number of actions of the first valve can be adjusted according to different stages of thermal runaway to dynamically adjust the amount and timing of the thermal runaway inhibitor.

[0096] For example, in the early stage of thermal runaway, a small amount of thermal runaway inhibitor can be injected; in the middle and late stages of thermal runaway, the number of actions of the first valve can be increased, the interval time of the first valve action can be reduced, and the amount of the thermal runaway inhibitor can be increased.

[0097] S105. The second valve is controlled to act by the second valve control instruction, so that the thermal runaway inhibitor enters the abnormal battery pack.

[0098] In combination with steps S102 and S105, in the present scheme, the thermal runaway inhibitor can be determined according to the type of the battery pack, for example, the thermal runaway inhibitor can be aerosol, perfluorohexone, etc.

[0099] In the present scheme, the first valve and the second valve are set as electrically controlled valves, wherein one or more first valves can be arranged in the cabin of the energy storage power station, and each battery pack is configured with a second valve.

[0100] For example, in the present scheme, the first valve is connected to the thermal runaway inhibitor storage device through the first pipeline, and the thermal runaway inhibitor storage device is used to store and externally deliver the thermal runaway inhibitor at a certain pressure.

[0101] For example, in the present scheme, the second valve is arranged on the battery pack and has no connection relationship with the thermal runaway inhibitor storage device.

[0102] Figure 2 is a structural block diagram of the fire extinguishing control system of the energy storage power station in the embodiment. Referring to Figure 2, in an implementable scheme, the energy storage power station can be configured with a fire extinguishing control system, and the fire extinguishing control system comprises:

[0103] The battery pack thermal runaway controller 1, the thermal runaway inhibitor storage device 2, the first valve 3, a plurality of sensors (sensors 1-1 to 1-n), and a plurality of second valves (second valves 1-1 to 1-n).

[0104] The battery pack thermal runaway controller 1 is in communication connection with the first valve 3, the sensors, and the second valves, and the thermal runaway inhibitor storage device 2 is connected to the first valve 3.

[0105] The first valve 3 and the second valves are electrically controlled valves, and the first valve 3, the second valves, and the sensors are further configured with a direct current power supply (not shown in the figure).

[0106] Exemplarily, in the scheme, the battery pack thermal runaway controller 1 is configured to execute any one of the energy storage power station fire extinguishing control methods described in the embodiments of the application.

[0107] Exemplarily, in the scheme, the thermal runaway inhibitor storage device 2 can store the thermal runaway inhibitor and a driving gas with a certain pressure, and the driving gas is used to push the thermal runaway inhibitor out of the thermal runaway inhibitor storage device 2 when the thermal runaway inhibitor needs to be sprayed; wherein the driving gas can be carbon dioxide, nitrogen, compressed air, etc.

[0108] Exemplarily, in the scheme, the sensor can be configured in the battery pack, and the sensor can be a composite detector, and one composite detector can be used to measure multiple physical quantities.

[0109] Exemplarily, in the scheme, the second valve can be configured on or in the battery pack, for example, the second valve can be an electric explosion valve.

[0110] Exemplarily, in the scheme, the sensor, the first valve 3, and the second valve can be connected to the battery pack thermal runaway controller 1 based on a communication bus;

[0111] Wherein, the communication bus can be a CAN bus, a PROFIBUS bus, a DeviceNet bus, etc.

[0112] Exemplarily, in the scheme, the battery pack thermal runaway controller 1 obtains battery pack internal abnormality detection information of each battery pack through the sensor, and obtains battery pack code information through the sensor or the BMS of the battery pack.

[0113] The battery pack thermal runaway controller 1 determines whether the battery pack is an abnormal battery pack according to the battery pack internal abnormality detection information, and generates a first valve control instruction and a second valve control instruction corresponding to the abnormal battery pack when there is an abnormal battery pack.

[0114] In the scheme, the first valve control instruction is used to control the action of the first valve, and the second valve control instruction is used to control the action of the specified second valve.

[0115] For example, when the battery pack 1-1 and the battery pack 1-n are abnormal battery packs, the first valve control instruction controls the first valve to open or close multiple times, so that the thermal runaway inhibitor can be sprayed into the cabin of the energy storage power station at intervals multiple times, and the second valve control instruction controls the second valve 1-1 and the second valve 1-n to act, so that the thermal runaway inhibitor can enter the inside of the battery pack 1-1 and the battery pack 1-n.

[0116] The embodiment provides a fire extinguishing control method for an energy storage power station, which comprises the following steps: determining whether a battery pack is in thermal runaway abnormality according to battery pack internal abnormality detection information; when the battery pack is in thermal runaway abnormality, the specific position of the abnormal battery pack can be determined according to battery pack coding information; when the abnormal battery pack exists, a first valve control instruction can be generated, the first valve is controlled to act multiple times through the first valve control instruction, and the abnormal battery pack can be effectively prevented from re-igniting through multiple injection of thermal runaway inhibitor. In addition, a second valve control instruction specially for the abnormal battery pack is generated, the second valve corresponding to the abnormal battery pack is controlled to act through the second valve control instruction, and the second valve of the remaining battery packs does not act, so that the thermal runaway of the abnormal battery pack is inhibited, and the utilization rate and the thermal runaway inhibition effect of the thermal runaway inhibitor are improved.

[0117] FIG. 3 is a flowchart of another fire extinguishing control method for an energy storage power station in the embodiment. Referring to FIG. 3, the fire extinguishing control method for the energy storage power station comprises the following steps in a kind of implementable scheme based on the scheme shown in FIG. 1:

[0118] S101. Obtain battery pack internal abnormality detection information of each battery pack and battery pack coding information of each battery pack.

[0119] S102. Determine whether the battery pack internal abnormality detection information matches a battery pack thermal runaway inhibition trigger condition; when the battery pack internal abnormality detection information matches the battery pack thermal runaway inhibition trigger condition, it is determined that at least one abnormal battery pack exists, and a first valve control instruction is generated.

[0120] S103. According to the battery pack coding information corresponding to the abnormal battery pack, a second valve control instruction is generated.

[0121] S104. The first valve is controlled to act multiple times through the first valve control instruction to spray the thermal runaway inhibitor to the area where the abnormal battery pack belongs multiple times.

[0122] S105. The second valve is controlled to act through the second valve control instruction to make the thermal runaway inhibitor enter the abnormal battery pack.

[0123] S106. Obtain battery cabin internal abnormality detection information of the battery cabin.

[0124] In the scheme, the battery cabin is set as the cabin body of the energy storage power station, and the battery cabin internal abnormality detection information contains a specified kind of physical measurement quantity, which can be the same as or different from the kind of physical measurement quantity contained in the battery pack internal abnormality detection information.

[0125] In the scheme, the selected physical measurement quantity for the battery cabin internal abnormality detection information is used to determine whether a fire occurs or is about to occur in the battery cabin.

[0126] Exemplarily, in the scheme, according to the physical measurement corresponding to the battery cabin abnormality detection information, one or more sensors can be arranged in the battery cabin, the corresponding physical quantity in the battery cabin is measured by the sensor in the battery cabin, and then the battery cabin abnormality detection information is formed.

[0127] S107. When the battery cabin abnormality detection information of the battery cabin matches the battery cabin thermal runaway suppression trigger condition, a third valve control instruction is generated.

[0128] In the scheme, when the physical measurement contained in the battery cabin abnormality detection information is in the specified numerical interval, it is considered that the battery cabin abnormality detection information matches the battery cabin thermal runaway suppression trigger condition, and when the physical measurement contained in the battery cabin abnormality detection information is not in the specified numerical interval, it can be considered that the battery cabin abnormality detection information does not match the battery cabin thermal runaway suppression trigger condition.

[0129] Wherein, the numerical interval corresponding to each physical measurement can be determined according to test data or simulation data, and the numerical interval should meet: when the battery cabin abnormality detection information matches the battery cabin thermal runaway suppression trigger condition, the battery cabin has or is about to have a fire.

[0130] S108. The third valve is controlled to act by the third valve control instruction, so that the thermal runaway suppression agent enters the battery cabin.

[0131] Exemplarily, in the scheme, if the battery pack has a thermal runaway failure, the first valve and the second valve are controlled to act, if the battery cabin has a fire, the third valve is controlled to act, and if the battery pack has a thermal runaway and the battery cabin has a fire, the first valve, the second valve and the third valve are controlled to act.

[0132] Exemplarily, in the scheme, the first valve and the third valve can share one thermal runaway suppression agent storage device; the first valve and the third valve can also be connected with different thermal runaway suppression agent storage devices, and when multiple thermal runaway suppression agent storage devices are used, different thermal runaway suppression agent storage devices can store different types of thermal runaway suppression agents; for example, the thermal runaway suppression agent storage device connected with the first valve can store perfluoroacetone, and the thermal runaway suppression agent storage device connected with the third valve can store aerosol.

[0133] In the scheme, whether the battery cabin has a fire is determined by the battery cabin abnormality detection information, when the fire occurs, the third valve control instruction is generated, and then the fire control for the battery cabin is effectively realized. The energy storage power station fire extinguishing control method proposed in the scheme can realize the thermal runaway monitoring and control of the battery cabin level and the battery pack level, the fire extinguishing effect is obvious, and the rekindling rate is low.

[0134] On the basis of any of the preceding schemes, in an implementable scheme, the method further comprises determining the battery cluster to which the abnormal battery pack belongs according to the battery pack coding information; and generating the first valve control instruction according to the battery cluster to which the abnormal battery pack belongs.

[0135] In this scheme, the first valve control instruction is used to control the at least one first valve to act multiple times to spray the thermal runaway inhibitor to the battery cluster to which the abnormal battery pack belongs multiple times.

[0136] In this scheme, a plurality of battery packs are arranged to form a battery cluster, and the battery pack coding information corresponding to each battery pack comprises a battery cluster identification code, and the battery cluster identification codes corresponding to the battery packs in the same battery cluster are set to be the same; for example, the battery pack coding information can be a ten-bit binary code, the first two binary code data bits correspond to the battery cluster identification code, and the last eight binary code data bits correspond to the battery pack identification code.

Referring to FIGS. 2 and 4, in an implementable scheme, the energy storage power station comprises a plurality of battery clusters (battery clusters 1-n), and the fire extinguishing control system comprises a plurality of first valves (first valves 1-n).

[0138] In this scheme, a battery cluster comprises a plurality of battery packs, and each battery pack is configured with at least one sensor and one second valve.

[0139] In this scheme, a battery cluster is configured with at least one first valve, and the thermal runaway inhibitor storage device 2 is connected to each first valve through a pipeline.

[0140] Referring to FIG. 4, optionally, the fire extinguishing control system can further comprise a repeater 4, and the battery pack thermal runaway controller 1 is connected to the first valve, the second valve, and the sensor configured in the battery pack through the repeater 4.

[0141] Illustratively, the repeater is a connection device applied to the network physical layer, which is mainly used to connect a plurality of network segments, thereby increasing the number of connectable nodes in the network to some extent, so that more devices can access the network.

[0142] In this scheme, the repeater 4 is configured to communicate with the sensor configured in the battery pack, receive the measurement of the sensor, and receive the working state of the sensor; the repeater 4 is configured to provide a direct-current working power supply for the sensor; the battery pack thermal runaway controller is configured to perform address coding for the sensor through the repeater 4 to form battery pack coding information, receive the measurement, alarm information, fault information, and start information of the sensor through the repeater 4; and the battery pack thermal runaway controller is configured to issue the first valve control instruction and the second valve control instruction through the repeater 4 to drive the opening and closing of the first valve and the second valve, thereby realizing the thermal runaway suppression at the battery cluster level and the battery pack level.

[0143] Exemplarily, in the scheme, the repeater 4 can be connected with the sensors configured in the battery pack through the coding line, and the repeater 4 can be connected with the first valve and the second valve through the communication bus (for example, CAN bus).

[0144] In the scheme, the coding line is used to transmit the data collected by the sensor to the repeater 4 for processing. According to the type of the sensor, the coding line matching the type of the sensor is selected, and the data transmission is realized based on the corresponding data transmission format and protocol.

[0145] In the scheme, the fire extinguishing control system can be configured with a third valve 5, and the battery pack thermal runaway controller 1 is connected with the third valve 5.

[0146] In the scheme, the first valve control instruction is generated according to the battery pack abnormality detection information and the battery pack coding information, and the second valve control instruction is generated according to the battery pack abnormality detection information and the battery pack coding information. For example, when the battery pack 2-1 is an abnormal battery pack, the battery pack 2-1 belongs to the battery cluster 2, the first valve control instruction controls one or more first valves configured in the battery cluster 2 to open or close multiple times, so that the thermal runaway inhibitor can be sprayed into the space region where the battery cluster 2 is located at intervals; the second valve control instruction controls the second valve 2-1 to act, so that the thermal runaway inhibitor can enter the inside of the battery pack 2-1.

[0147] On the basis of any of the foregoing schemes, in an implementable scheme, the battery pack abnormality detection information includes one or more of carbon monoxide detection data, first smoke detection data, first temperature detection data, and organic compound particle detection data.

[0148] Exemplarily, in the scheme, the sensor configured in the battery pack can be a composite detector. For example, the sensor configured in the battery pack can be a four-in-one composite detector (simultaneously measuring carbon monoxide, smoke, temperature, and organic compounds).

[0149] Exemplarily, in the scheme, the four-in-one composite detector can be arranged in the battery pack, and one battery pack is configured with one four-in-one composite detector. The four-in-one composite detector is used to measure the carbon monoxide, smoke, temperature, and organic compounds in the battery pack.

[0150] Exemplarily, in the scheme, for each measurement, a corresponding detection threshold value can be configured, and whether the battery pack is an abnormal battery pack is determined based on the comparison result of the measurement and the detection threshold value. In this scheme, when one or more measurements are greater than the corresponding detection threshold value, the battery pack is determined to be an abnormal battery pack.

[0151] In the foregoing scheme of battery pack internal abnormality detection information including carbon monoxide detection data, first smoke detection data, first temperature detection data, and organic compound particle detection data, in an implementable scheme, if the carbon monoxide detection data is greater than a carbon monoxide threshold value, the first smoke detection data is greater than a smoke threshold value, the first temperature detection data is greater than a temperature threshold value, or the organic compound particle detection data is greater than an organic compound particle threshold value, it is determined that the battery pack internal abnormality detection information matches a battery pack thermal runaway suppression trigger condition.

[0152] In the foregoing scheme, the carbon monoxide threshold value, the smoke threshold value, the temperature threshold value, and the organic compound particle threshold value can be determined by experience or simulation test; and the numerical range of the carbon monoxide threshold value, the smoke threshold value, the temperature threshold value, and the organic compound particle threshold value can be 100-1000 ppm (parts per million).

[0153] In the foregoing scheme, when the numerical value of one or more measured quantities is greater than the corresponding threshold value, it can be determined that the battery pack internal abnormality detection information matches the battery pack thermal runaway suppression trigger condition.

[0154] In the foregoing scheme, according to the battery pack internal abnormality detection information, the level of thermal runaway of the battery pack can be classified, and different thermal runaway control strategies can be executed according to different levels.

[0155] In the foregoing scheme, the carbon monoxide threshold value includes a first carbon monoxide threshold value, a second carbon monoxide threshold value, and a third carbon monoxide threshold value, the smoke threshold value includes a first smoke threshold value, a second smoke threshold value, and a third smoke threshold value, the temperature threshold value includes a first temperature threshold value, a second temperature threshold value, and a third temperature threshold value, and the organic compound particle threshold value includes a first organic compound particle threshold value, a second organic compound particle threshold value, and a third organic compound particle threshold value; when the battery pack internal abnormality detection information includes carbon monoxide detection data, first smoke detection data, first temperature detection data, and organic compound particle detection data, if the carbon monoxide detection data is greater than the first carbon monoxide threshold value, the first smoke detection data is greater than the first smoke threshold value, the first temperature detection data is greater than the first temperature threshold value, or the organic compound particle detection data is greater than the first organic compound particle threshold value, a first-level warning instruction is generated.

[0156] If the carbon monoxide detection data is greater than the second carbon monoxide threshold value, the first smoke detection data is greater than the second smoke threshold value, the first temperature detection data is greater than the second temperature threshold value, or the organic compound particle detection data is greater than the second organic compound particle threshold value, a second-level warning instruction is generated.

[0157] If the carbon monoxide detection data is greater than a third carbon monoxide threshold value, the first smoke detection data is greater than a third smoke threshold value, the first temperature detection data is greater than a third temperature threshold value, or the organic compound particle detection data is greater than a third organic compound particle threshold value, a third level warning instruction is generated.

[0158] For example, in this scheme, the fire extinguishing control system can also be configured with a warning indication device, which can output sound, light and other alarm signals.

[0159] For example, in this scheme, the first, second and third level warning instructions are used to control the warning indication device to output different warning signals; for example, the warning indication device can be an indicator, and the first, second and third level warning instructions can be used to control the indicator to emit green, yellow and red warning light signals, respectively.

[0160] For example, in this scheme, the heat runaway levels corresponding to the first, second and third level warnings increase in turn. For example, the first carbon monoxide threshold value can range from 100 to 200 ppm, the second carbon monoxide threshold value can range from 300 to 500 ppm, and the third carbon monoxide threshold value can range from 600 to 800 ppm.

[0161] For example, in this scheme, the software method used to determine the warning level is not limited, for example, the warning level determination method described in 202311282879.9 can be used to determine the warning level in this scheme.

[0162] In this scheme, it is provided that when the third level warning instruction is generated, it is determined that the abnormal detection information in the battery pack matches the battery pack heat runaway suppression trigger condition.

[0163] On the basis of any of the preceding schemes, in an implementable scheme, the energy storage power station fire extinguishing control method further comprises obtaining heat runaway suppressant storage device pressure detection information; generating a heat runaway suppression execution prompt instruction according to the heat runaway suppressant storage device pressure detection information.

[0164] In this scheme, it is provided that the heat runaway suppression execution prompt instruction is used to control the alarm indication device to output an alarm prompt signal.

[0165] In this scheme, the heat runaway suppressant storage device can be provided with a pressure sensor connected to the battery pack heat runaway controller, which is used to measure the (internal) pressure of the heat runaway suppressant storage device, which can be used to determine whether the heat runaway suppressant storage device is ejecting heat runaway suppressant.

[0166] In an example, the heat run-away suppression execution prompting instruction is generated when the heat run-away suppression agent storage device is determined to be ejecting the heat run-away suppression agent outwards based on the heat run-away suppression agent storage device pressure detection information.

[0167] In an example, the heat run-away suppression agent storage device is determined to be ejecting the heat run-away suppression agent outwards when the pressure of the heat run-away suppression agent storage device is determined to be decreasing based on the heat run-away suppression agent storage device pressure detection information.

[0168] In an example, the alarm prompting signal outputted by the alarm indicating device when the alarm indicating device is actuated based on the heat run-away suppression execution prompting instruction is used to indicate that the heat run-away suppression agent storage device is ejecting the heat run-away suppression agent outwards.

[0169] In the foregoing energy storage power station with battery cluster arrangement, in an example implementation, the first valve control instruction includes a bottle head valve control instruction and a battery cluster valve control instruction, the bottle head valve control instruction is used to control the actuation of the bottle head valve of the heat run-away suppression agent storage device, and the battery cluster valve control instruction is used to control the actuation of the battery cluster valve corresponding to the battery cluster containing the abnormal battery pack.

[0170] In an example, the first valve includes a bottle head valve and a battery cluster valve, the bottle head valve is arranged at the ejection outlet position of the heat run-away suppression agent storage device, and one battery cluster is configured with one or more battery cluster valves.

[0171] In an example, the heat run-away suppression agent storage device is connected to the bottle head valve, and the bottle head valve is connected to the battery cluster valve through a pipeline.

[0172] In an example, the battery pack 2-1 belongs to the battery cluster 2, when the battery pack 2-1 is an abnormal battery pack, the battery pack heat run-away controller controls the opening of the bottle head valve (using the bottle head valve control instruction) and controls the opening and closing of the one or more battery cluster valves of the battery cluster 2 (using the battery cluster valve control instruction) multiple times, so that the heat run-away suppression agent can be ejected into the space region where the battery cluster 2 is located multiple times at intervals.

[0173] In the foregoing fire extinguishing control system including a third valve, in an example implementation, the third valve control instruction includes a bottle head valve control instruction and a battery cabin valve control instruction, the bottle head valve control instruction is used to control the actuation of the bottle head valve of the heat run-away suppression agent storage device, and the battery cabin valve control instruction is used to control the actuation of the battery cabin valve corresponding to the battery cabin.

[0174] Exemplarily, in the solution, the third valve is configured to include a bottle head valve and a battery cabin valve, wherein the bottle head valve is arranged at an injection (of the thermal runaway suppressant) outlet of the thermal runaway suppressant storage device, and the battery cabin (of the energy storage power station) can be configured with one or more battery cabin valves.

[0175] Exemplarily, in the solution, the thermal runaway suppressant storage device is connected to the bottle head valve, and the bottle head valve is connected to the battery cabin valve through a pipeline.

[0176] Exemplarily, in the solution, when it is determined that a fire occurs in the battery cabin based on the battery cabin abnormality detection information, the battery pack thermal runaway controller controls the bottle head valve to open by using a bottle head valve control instruction, and controls the battery cabin valve to open by using a battery cabin valve control instruction, so that the thermal runaway suppressant enters the battery cabin.

[0177] Based on any of the foregoing solutions, in an implementable solution, the battery cabin abnormality detection information includes second smoke detection data and / or second temperature detection data.

[0178] Exemplarily, in the solution, a smoke sensor and a temperature sensor can be arranged in the battery cabin, the smoke sensor arranged in the battery cabin is used to measure the smoke in the battery cabin, and the second smoke detection data is formed accordingly, and the temperature sensor arranged in the battery cabin is used to measure the temperature in the battery cabin, and the second temperature detection data is formed accordingly.

[0179] Exemplarily, in the solution, corresponding smoke detection threshold and temperature detection threshold can be configured for the smoke measurement and the temperature measurement, and it is determined that a fire occurs in the battery cabin when the smoke amount is greater than the smoke detection threshold and the temperature measurement is greater than the temperature detection threshold (i.e., when the battery cabin abnormality detection information matches the battery cabin thermal runaway suppression trigger condition).

[0180] Based on the solution in which the battery cabin abnormality detection information includes the second smoke detection data and the second temperature detection data, in an implementable solution, if the second smoke detection data is greater than a fourth smoke threshold and the second temperature detection data is greater than a fourth temperature threshold, it is determined that the battery cabin abnormality detection information matches the battery cabin thermal runaway suppression trigger condition.

[0181] Exemplarily, in the solution, the fourth smoke threshold and the fourth temperature threshold can be determined by experience or simulation test, and the numerical range of the fourth smoke threshold and the fourth temperature threshold can be 500-800 ppm.

[0182] Based on any of the foregoing solutions, in an implementable solution, the energy storage power station fire extinguishing control method further includes obtaining combustible gas detection data.

[0183] When the combustible gas detection data is greater than the combustible gas threshold value, and the battery cabin internal abnormality detection information does not match the battery cabin thermal runaway suppression trigger condition, an exhaust control instruction is generated.

[0184] For example, in this scheme, the combustible gas can be hydrogen, carbon monoxide, methane, etc.

[0185] For example, in this scheme, when the combustible gas includes multiple types, the combustible gas threshold value corresponds to multiple types. When one or more combustible gas detection data is greater than the combustible gas threshold value, and the battery cabin internal abnormality detection information does not match the battery cabin thermal runaway suppression trigger condition, an exhaust control instruction is generated.

[0186] In this scheme, the exhaust control instruction is configured to control the exhaust of the combustible gas in the battery cabin.

[0187] For example, in this scheme, the energy storage power station can include an exhaust system, which can include an exhaust fan. The battery pack thermal runaway controller controls the exhaust system to act according to the exhaust control instruction to exhaust the combustible gas from the battery cabin.

[0188] For example, in this scheme, the battery cabin is a closed environment. The purpose of controlling the exhaust system to exhaust the combustible gas in the battery cabin is to avoid the problem that the concentration of combustible gas increases continuously when the battery is running for a long time, resulting in an explosion risk.

[0189] Based on the foregoing scheme of generating an exhaust control instruction, in an implementable scheme, when the exhaust control instruction is executed, if the battery cabin internal abnormality detection information matches the battery cabin thermal runaway suppression trigger condition, an exhaust stop control instruction is generated.

[0190] After the exhaust stop control instruction is executed, a third valve control instruction is executed after a preset time delay.

[0191] In this scheme, the exhaust stop control instruction is configured to control the stop of the exhaust of the combustible gas in the battery cabin. The battery pack thermal runaway controller controls the exhaust system to stop acting according to the exhaust stop control instruction.

[0192] In this scheme, when the exhaust system is acting, if it is determined based on the battery cabin internal abnormality detection information that a fire occurs in the battery cabin, an exhaust stop control instruction and a third valve control instruction are generated. The exhaust system is controlled to stop acting according to the exhaust stop control instruction. After a preset time delay, the third valve is controlled to act according to the third valve control instruction, so that the thermal runaway suppression agent enters the battery cabin to extinguish the fire in the battery cabin.

[0193] Exemplarily, in the present scheme, the preset time can be 0-30 seconds. The purpose of executing the third valve control instruction after the preset time is to avoid the possibility that the air duct of the exhaust system may form a ventilation channel when a fire occurs, causing the fire to spread rapidly along the air duct; and to avoid the possibility that the exhaust system continues to run, causing the fire extinguishing medium to be quickly discharged and making it difficult to form an effective fire extinguishing concentration in the fire area.

[0194] On the basis of any of the foregoing schemes, in an implementable scheme, the energy storage power station fire extinguishing control method further comprises generating a battery management system linkage control signal; the battery management system linkage control signal is used to instruct the battery management system to disconnect the system power supply of the energy storage power station.

[0195] Exemplarily, in the present scheme, the battery management system is a BMS configured for the energy storage power station, wherein the functions of the BMS can include: monitoring of the voltage, current, temperature, and insulation resistance of the battery pack; estimation of the state of charge (SOC) of the battery pack, evaluation of the state of health (SOH), and evaluation of the power state; overcharge protection, overdischarge protection, overcurrent protection, temperature protection, and short-circuit protection of the battery pack; equalization management, energy control management, and power control.

[0196] Since there are inevitably some differences among the single batteries in the battery pack during the production and manufacturing process, and the aging degrees of different single batteries are also different during use, leading to inconsistent performance of different single batteries in the battery pack; the equalization management function of the BMS can balance the charging or discharging of the single batteries in the battery pack, so that the voltage, capacity, and other parameters of different single batteries are kept at a relatively consistent level, thereby improving the overall performance and service life of the battery pack.

[0197] According to the operating requirements of the energy storage power station and the state of the battery, the BMS can accurately control the charging and discharging process of the battery. For example, during the low-load period of the power grid, the battery is controlled to charge and store energy; during the peak load period of the power grid, the battery is controlled to discharge, releasing the stored energy into the power grid to achieve the function of peak shaving and valley filling; in addition, the BMS can adjust and control the charging and discharging power of the battery according to the demand of the power grid and the capacity of the battery, to ensure the stable connection and efficient operation of the energy storage system and the power grid.

[0198] In the present scheme, when there is an abnormal battery pack or the abnormal detection information in the battery cabin matches the battery cabin thermal runaway suppression trigger condition, a battery management system linkage control signal is generated, and the battery management system linkage control signal is used to cut off the charging and discharging circuit of the energy storage power station by the BMS; wherein the BMS can be configured to disconnect the charging and discharging circuit of the energy storage power station by disconnecting the relays in the charging and discharging circuit.

[0199] On the basis of the foregoing scheme in which the first valve control instruction includes the bottle head valve control instruction and the battery cluster valve control instruction, in an implementable scheme, the battery pack abnormality detection information, the battery cluster valve control instruction, and the second valve control instruction are transmitted based on a CAN communication protocol; and the battery compartment abnormality detection information is transmitted based on a serial bus protocol.

[0200] For example, in this scheme, the battery pack can be provided with a composite detector, the composite detector, the battery cluster valve, and the second valve can be connected to the battery pack thermal runaway controller through a CAN bus; the battery compartment detection sensor can be connected to a fire extinguishing controller, the fire extinguishing controller is connected to the battery pack thermal runaway controller through a serial bus, and the battery pack thermal runaway controller acquires the battery compartment abnormality detection signal through the fire extinguishing controller.

[0201] For example, in this scheme, the specific functions of the fire extinguishing controller are not limited, for example, the fire extinguishing controller can realize the functions of alarming when a fire occurs in the battery compartment, manually controlling the third valve, etc.

When the exhaust air control instruction is executed, if the abnormality detection information in the battery cabin matches the battery cabin thermal runaway suppression trigger condition, generate an exhaust air stop control instruction, a bottle head valve control instruction, a battery cabin valve control instruction, and a battery management system linkage control signal.

[0238] In this scheme, the battery cluster valve is set as the first valve, the electric explosion valve is set as the second valve, and the battery cabin valve is set as the third valve.

[0239] In this scheme, the fire extinguishing control system can realize automatic fire detection and extinguishing in the battery cabin, including:

[0240] When the combustible gas detector (not shown in the figure) detects that the combustible gas concentration in the battery cabin exceeds the combustible gas threshold, a combustible gas alarm information is generated;

[0241] The combustible gas alarm information is transmitted to the gas fire extinguishing controller 82, and the gas fire extinguishing controller 82 controls the exhaust fan 71 and the pressure reducing valve 72 to start working;
