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 specific embodiments. Detailed Implementation

[0043] 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.

[0044] With the rapid development of electrochemical energy storage technology, energy storage systems have become core equipment on the generation, grid, and user sides. Among these, energy storage battery devices are widely used in energy storage power stations and other similar scenarios. However, energy storage battery devices are prone to fire, posing a serious threat to the safety of personnel and property. Therefore, the fire safety of energy storage battery devices is crucial for the overall operational safety of energy storage power stations and for preventing the spread of fire.

[0045] Currently, the fire protection systems for existing energy storage battery devices are primarily designed and installed by a single supplier, who also provides the overall solution. Many of the components used in these systems also come from a single supplier. Therefore, the reliance on a single supplier in the fire protection systems of existing energy storage battery devices leads to poor system compatibility and low response efficiency.

[0046] Considering the aforementioned problems with existing fire suppression systems for energy storage battery devices, this application proposes a fire suppression system that does not rely on a single supplier. Through this method, and via modular design, the compatibility and response efficiency of the fire suppression system for energy storage battery devices are improved.

[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These 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.

[0048] Figure 1 This is a schematic diagram of the fire protection system architecture for an energy storage battery device provided in this application. Figure 1 As shown, the fire protection system includes a detection module, a control module, a fire extinguishing module, and a communication module. The control module is connected to the detection module, the communication module, and the fire extinguishing module, respectively. The communication module is also connected to the target system.

[0049] The detection module can be used to collect fire characteristic data and transmit the fire characteristic data to the control module.

[0050] For example, fire characteristic data can be temperature-related characteristic data, gas-related characteristic data, and smoke-related characteristic data. For instance, fire characteristic data could be the surface temperature data of individual battery cells in an energy storage battery device, the concentration of characteristic gases released (carbon monoxide, hydrogen, etc.), or smoke concentration data.

[0051] For example, the detection module can be a detection unit employing a distributed sensor array. For instance, the distributed sensor array can be an array integrating temperature sensors, smoke sensors, and combustible gas sensors.

[0052] Optionally, the detection module of this fire protection system can, for example, directly contact the energy storage battery being detected and collect fire characteristic data such as temperature features through an integrated distributed sensor array. The detection module can also collect fire characteristic data by monitoring changes in the local environment of the detected object. The detection module can, for example, transmit the collected fire characteristic data to the control module via a communication protocol. This communication protocol could be, for example, a Transmission Control Protocol / Internet Protocol (TCP / IP).

[0053] The control module can be used to generate fire extinguishing control commands when a fire is determined to exist based on the fire characteristic data, and transmit the fire extinguishing control commands to the fire extinguishing module and the communication module.

[0054] In some embodiments, the control module includes: a first interface for connecting to the detection modules from different manufacturers; the detection modules from different manufacturers meet the requirements of external communication interface standardization and mounting hole consistency.

[0055] For example, the first interface may be a standardized interface used to connect the physical port of the aforementioned detection module and its associated communication protocol stack. For instance, the first interface may be a standard bus interface or a standard network interface, and it may also support automatic identification or manual configuration of the communication protocol used to access the detection module.

[0056] For example, detection modules from different manufacturers may involve detection modules with standardized external communication interfaces and consistent mounting hole positions.

[0057] Optionally, the control module of the fire protection system can, for example, be based on a standardized first interface and can be connected to detection modules from different manufacturers that meet the standardization of external communication interfaces and the consistency of installation hole design through standard installation specifications and communication protocol standards.

[0058] Using the above method, the control module of the fire protection system includes a detection module that can be connected to devices from different manufacturers, thus improving the compatibility of devices from different manufacturers.

[0059] In some embodiments, the control module of the fire protection system is also connected to a target power source, which powers the control module; the control module also powers the aforementioned detection module.

[0060] For example, the target power source can be one or more power supply devices or systems that provide power to the control module. For instance, the target power source can be a power supply from the energy storage battery device itself, or it can be a built-in battery pack that serves as a backup power source.

[0061] Optionally, the control module of the fire protection system can be connected to a target power source to obtain power. At the same time, the control module can also provide power to the detection module by connecting to the aforementioned detection module.

[0062] For example, the control module may be the core decision-making module of the fire protection system. For instance, the control module may include a fire alarm controller, an intelligent algorithm processing unit, and a compatible interface supporting access to detection modules from multiple manufacturers. For instance, the control module may be a computing unit module comprising hardware and software, responsible for receiving, processing, and analyzing all data streams from the detection modules, executing preset fire judgment logic algorithms, and, upon confirming a fire, issuing a sequence of fire extinguishing control commands to the fire extinguishing module and the communication module.

[0063] For example, the fire extinguishing control command may be a sequence of commands generated by the control module to trigger the fire extinguishing module to perform a specific action. For example, the fire extinguishing control command may include command type and execution parameters, such as a fire extinguishing control command like "start the directional spray device, spray duration 10 seconds".

[0064] Optionally, the control module of the fire protection system can receive fire characteristic data transmitted from the detection module and analyze whether a fire exists using an intelligent algorithm within the control module. When the fire protection system confirms the existence of a fire, it generates a fire extinguishing control command to trigger the fire extinguishing module to perform specific actions. Simultaneously, the control module can also send the fire extinguishing control command to the fire extinguishing module and the communication module via a serial bus.

[0065] The fire suppression module can be used to perform fire suppression operations on the energy storage battery device in response to the fire suppression control command.

[0066] For example, a fire extinguishing module can be a core functional unit responsible for performing fire extinguishing actions, including multiple independent fire extinguishing sub-modules.

[0067] For example, a fire suppression control instruction may include the fire level. Alternatively, the fire suppression instruction may include the fire location. Or, the fire suppression instruction may include both the fire level and the fire location.

[0068] For example, the fire rating can be the severity of the fire as determined by fire control instructions. For instance, the fire rating can be minor, moderate, or severe.

[0069] For example, the fire location can be the specific area where the fire occurred, as determined by the aforementioned detection module. For instance, the fire location could be a battery compartment section or a battery rack number.

[0070] Optionally, the fire suppression module of the fire protection system can receive a fire suppression control command from the control module and perform fire suppression operations on the energy storage battery device based on the fire level in the fire suppression control command. The fire suppression module can also perform fire suppression operations on the energy storage battery device based on the fire location in the fire suppression control command. Alternatively, the fire suppression module can perform fire suppression operations on the energy storage battery device based on both the fire level and the fire location in the fire suppression control command.

[0071] The communication module can be used to interact with the target system in response to the fire extinguishing control command.

[0072] For example, the communication module can be a unit that, upon receiving a fire extinguishing control command, interacts with the target system regarding the status of the fire protection system, alarm information, and the fire extinguishing control command itself.

[0073] For example, the target system can be a battery management system (BMS) or an energy management system (EMS). The target system can also be both a battery management system (BMS) and an energy management system (EMS).

[0074] In some embodiments, the communication module is further configured to: obtain a first identifier of the detection module and a second identifier of the control module from the control module; then, determine a target communication protocol with the target system based on the first identifier and the second identifier; and then, specifically, the communication module is configured to interact with the target system via the target communication protocol in response to the fire extinguishing control command.

[0075] For example, the first identifier could be used to distinguish different types, manufacturers, or versions of detection modules.

[0076] For example, the second identifier may be used to identify the model, hardware version, or firmware version of the control module itself.

[0077] For example, the target communication protocol could be the specific data format and exchange rules ultimately selected when the communication module successfully establishes a connection with the target system and exchanges data.

[0078] Optionally, the communication module of the fire protection system can obtain the first identifier of the detection module and the second identifier of the control module through active polling and reporting. For example, the communication module sends a "request system identifier" command to the control module. The control module, acting as an information hub, polls all the detection modules connected to it via the internal bus. Upon receiving the request, each detection module returns its first identifier (such as a data packet containing the manufacturer ID, device type, and firmware version) to the control module. The control module aggregates all the first identifiers, packages them together with its own second identifier, and sends them to the communication module.

[0079] Optionally, the communication module of the fire protection system can also load a first identifier of the detection module and a second identifier of the control module through a configuration file. For example, the communication module can obtain the first identifier of the detection module and the second identifier of the control module by reading a system configuration file pre-generated based on a configuration tool.

[0080] Optionally, the communication module can pre-set a mapping table based on the first identifier, the second identifier, and the communication protocol. By querying the mapping table, the target communication protocol between the module and the target system can be determined.

[0081] Optionally, the communication module can also determine its own capabilities based on the first identifier of the detection module and the second identifier of the control module. Then, the communication module can send its own capabilities to the target system and receive a list of supported protocols returned by the target system, select a common protocol from the list, and thus determine the target communication protocol with the target system.

[0082] Optionally, upon receiving the fire suppression control command, the communication module simultaneously interacts with the battery management system and the energy management system via a defined target communication protocol. For example, based on the target communication protocol, the communication module can send an "emergency stop" command to the battery management system through an independent communication channel, causing the battery management system to disconnect all controllers. Simultaneously, the communication module can send a "fire suppression system trip" signal to the energy management system, causing the energy management system to disconnect from the power grid and stop the inverter from charging and discharging.

[0083] Using the above method, the communication module of the fire protection system can determine the target communication protocol with the target system based on the first identifier of the control module and the second identifier of the detection module. Through this target communication protocol, data interaction can be achieved with the target system, improving the reliability and response speed of the fire protection system.

[0084] In this embodiment, the detection module of the fire protection system can collect fire characteristic data and transmit it to the control module, laying the foundation for subsequent processing operations based on the fire characteristic data. Based on the fire characteristic data, the control module of the fire protection system can determine whether a fire exists, and upon confirmation of a fire, a fire extinguishing control command can be obtained. Based on the fire extinguishing control command, the fire extinguishing module of the fire protection system can perform fire extinguishing operations on the energy storage battery device, achieving precise fire suppression. Based on the fire extinguishing control command, the communication module of the fire protection system can achieve data interaction with the target system. By modularly designing the fire protection system and defining standardized interfaces, the compatibility and response efficiency of the fire protection system are improved.

[0085] The following section details how the control module of the fire protection system determines whether a fire exists based on the fire characteristic data and the preset fire prediction threshold.

[0086] In some embodiments, the control module can be used to determine whether a fire exists based on the fire characteristic data and the preset fire prediction threshold. The control module is also used to collect environmental data of the environment in which the energy storage battery device is located via the aforementioned detection module. Then, based on the environmental data, the preset fire prediction threshold is updated.

[0087] For example, a fire prediction threshold can be one or more reference values ​​used to determine whether a fire exists, and can be dynamically adjusted based on environmental data. For instance, a fire prediction threshold could be a temperature threshold, a gas concentration threshold, or a delay concentration threshold, etc.

[0088] For example, environmental data can be condition data of the environment in which the energy storage battery device is located. For example, environmental data can be ambient temperature and humidity, ambient air pressure, or the operating status of the fire protection system.

[0089] Optionally, the control module of the fire protection system can, for example, analyze the fire characteristic data. When any type of characteristic data in the fire characteristic data exceeds a single preset fire prediction threshold, it can be determined that a fire actually exists. For example, if the temperature characteristic data in the fire characteristic data is 60 degrees Celsius, and the preset fire prediction threshold is 55 degrees Celsius, since the temperature characteristic data in the fire characteristic data exceeds the preset fire prediction threshold, the control module can determine that a fire exists.

[0090] Optionally, the control module of the fire protection system can assign different weights to different types of feature data in the fire feature data, and calculate a comprehensive probability score by fusing the different types of feature data. A fire is confirmed when the comprehensive probability score exceeds a preset fire prediction threshold. For example, the control module can set the weight of temperature feature data to 0.5, the weight of gas feature data to 0.3, and the weight of smoke feature data to 0.2. A fire is confirmed when the comprehensive probability score of the different types of feature data in the fire feature data exceeds the preset fire prediction threshold of 0.8.

[0091] Optionally, the control module of the fire protection system can collect environmental data of the environment where the energy storage battery device is located through the aforementioned detection module, and update the preset fire prediction threshold based on the environmental data. For example, the control module can pre-set a mapping table between environmental data and fire prediction thresholds based on historical data. When the environmental data changes, the preset fire prediction thresholds are updated by querying the mapping table.

[0092] Optionally, the control module of the fire protection system can also construct prompt words based on environmental data of the environment where the energy storage battery device is located and the operating status of the fire protection system, and input the prompt words into the predictive learning model to update the preset fire prediction threshold. The prompt words can be used to indicate the optimal fire prediction threshold based on the environmental data of the environment where the energy storage battery device is located and the operating status of the fire protection system. It should be understood that the implementation method of the predictive learning model outputting the optimal fire prediction threshold based on the environmental data of the environment where the energy storage battery device is located can, for example, refer to the training method of any existing deep learning model, which will not be elaborated here.

[0093] Using the above method, based on the fire characteristic data and the preset fire prediction threshold, the existence of a fire can be determined. The detection module can collect environmental data about the environment where the energy storage battery device is located. Based on this environmental data, the preset fire prediction threshold is updated, improving the adaptability of the fire protection system.

[0094] The following section provides a detailed explanation of how the fire suppression module of the fire protection system, in response to the fire suppression control command, performs fire suppression operations on the energy storage battery device.

[0095] In some embodiments, the fire suppression module includes: a plurality of independent fire suppression sub-modules; each fire suppression sub-module includes: an extinguishing agent storage unit and an extinguishing agent dispensing unit. The fire suppression control command includes: fire level, or the fire suppression control command includes: fire location. Alternatively, the fire suppression control command includes: fire level and fire location.

[0096] For example, the fire extinguishing submodule may be an independently controlled fire extinguishing submodule. For instance, a fire extinguishing submodule may have a separate fire extinguishing agent storage unit and a fire extinguishing agent dispensing unit, and the activation of each fire extinguishing submodule does not affect the status of other fire extinguishing submodules.

[0097] For example, the extinguishing agent storage unit can be a component designed to store extinguishing agents according to the type of extinguishing agent. The type of extinguishing agent can be, for example, dry powder, fluorinated ketone, or nitrogen.

[0098] For example, a fire extinguishing agent dispensing unit can be a component that delivers fire extinguishing agent to a designated area based on a valve. For instance, a fire extinguishing agent dispensing unit can be a stainless steel nozzle with a valve, or it can be an atomizing nozzle with a valve, etc.

[0099] As one possible implementation, the fire suppression module can be used to: in response to the fire suppression control command, determine a target fire suppression submodule from among the plurality of fire suppression submodules based on the fire level. Then, the fire suppression module controls the extinguishing agent storage unit and the extinguishing agent dispensing unit of the target fire suppression submodule to perform fire suppression operations on the energy storage battery device.

[0100] Optionally, the fire suppression module of the fire protection system can pre-set a mapping table between fire levels and fire suppression sub-module actions. This mapping table establishes a relationship between fire levels and the fire suppression sub-modules that should be activated. For example, when the fire suppression module receives the fire suppression control command, it queries the fire level-to-fire suppression sub-module mapping table based on the fire level to determine the target fire suppression sub-module.

[0101] Optionally, the fire protection module of the fire protection system can also perform fire extinguishing operations on the energy storage battery device by coordinating the fire extinguishing agent storage unit and the fire extinguishing agent injection unit of the target fire extinguishing submodule. For example, based on the control command of the fire extinguishing module of the fire protection system, the target fire extinguishing submodule opens the storage outlet valve of the fire extinguishing agent storage unit of the target fire extinguishing submodule and simultaneously opens the directional nozzle valve of the fire extinguishing agent injection unit of the target fire extinguishing submodule to perform fire extinguishing operations on the energy storage battery device.

[0102] As another possible implementation, the fire suppression module can also be used to: in response to the fire suppression control command, determine the target fire suppression submodule from the plurality of fire suppression submodules based on the fire location.

[0103] Optionally, the fire suppression module of the fire protection system can predefine an address mapping table. Based on this predefined address mapping table, the fire suppression submodule corresponding to the fire location can be determined, thereby identifying the target fire suppression submodule. For example, when the fire suppression module of the fire protection system receives the fire suppression control command, based on the fire location being zone B, it determines the fire suppression submodule in zone B as the target fire suppression submodule by querying the predefined address mapping table.

[0104] As another possible implementation, the fire suppression module can also be used to: in response to the fire suppression control command, determine the target fire suppression submodule from the plurality of fire suppression submodules based on the fire level and the fire location.

[0105] Optionally, the fire suppression module of the fire protection system can predefine a strategy mapping table, which may include: different fire levels, different fire locations, and the mapping relationship between the corresponding fire suppression sub-modules. When the control module of the fire protection system receives a fire suppression control command containing the fire level and fire location, it uses it as a joint query condition to retrieve the preset set of fire suppression sub-modules from the mapping table as the target fire suppression sub-module and execute the fire suppression operation.

[0106] Optionally, the fire suppression module of the fire protection system can also determine the target fire suppression sub-module based on different fire levels and fire locations through a dynamic evaluation model. For example, the fire suppression module of the fire protection system inputs the fire level and fire location into the dynamic evaluation model. The dynamic evaluation model can determine the basic risk level based on the fire level, and then, combined with the fire location, dynamically determine the target fire suppression sub-module that needs to be activated.

[0107] Using the above method, the fire suppression module of the fire protection system, responding to the fire suppression control command, can determine the target fire suppression submodule from among multiple fire suppression submodules based on the fire level. The fire suppression module of the fire protection system, responding to the fire suppression control command, can determine the target fire suppression submodule from among multiple fire suppression submodules based on the fire location. The fire suppression module of the fire protection system, responding to the fire suppression control command, can determine the target fire suppression submodule from among multiple fire suppression submodules based on both the fire level and the fire location. Then, the control module of the fire protection system can perform fire suppression operations on the energy storage battery device through the fire extinguishing agent storage unit and the fire extinguishing agent dispensing unit of the target fire suppression submodule, thereby improving the response efficiency of the fire protection system.

[0108] The following provides a detailed explanation of how the fire extinguishing module of the fire protection system controls the fire extinguishing agent storage unit and the fire extinguishing agent spraying unit of the target fire extinguishing submodule to perform fire extinguishing operations on the energy storage battery device.

[0109] In some embodiments, for any of the above-described fire extinguishing submodules, the fire extinguishing agent injection unit may include a valve. Specifically, the fire extinguishing module is used to control the opening degree of the valve of the fire extinguishing agent injection unit of the target fire extinguishing submodule to a target opening degree, thereby performing a fire extinguishing operation on the energy storage battery device.

[0110] Optionally, the fire suppression module of the fire protection system can predefine a mapping table between fire levels and target valve opening degrees. This mapping table can include the mapping relationship between different fire levels and different valve opening degrees. For example, when the fire level is early warning, the control module of the fire protection system can query the fire level and target valve opening degree mapping table to find that the valve opening degree of the fire extinguishing agent injection unit of the target fire suppression submodule is 30%. Then, the target opening degree of the valve of the fire extinguishing agent injection unit of the target fire suppression submodule is set to 30%, and the fire suppression operation is performed on the energy storage battery device.

[0111] Using the above method, the fire extinguishing module can control the opening degree of the valve of the fire extinguishing agent injection unit of the target fire extinguishing submodule to the target opening degree, and can perform fire extinguishing operation on the energy storage battery device, thereby improving the efficiency and accuracy of fire extinguishing agent use.

[0112] As one possible implementation, the fire extinguishing module also includes an energy recovery submodule for recovering the extinguishing agent after it has been sprayed.

[0113] Optionally, the energy recovery submodule may be, for example, a recovery system capable of recovering the extinguishing agent after it has been sprayed. For example, the energy recovery submodule may be a recovery system with selective adsorption and desorption.

[0114] This energy recovery submodule, after the fire extinguishing module of the fire protection system controls the fire extinguishing agent storage unit and the fire extinguishing agent injection unit to perform fire extinguishing operations on the energy storage battery device, utilizes adsorption materials to selectively adsorb fire extinguishing agent molecules. When the adsorption is saturated, the energy recovery submodule can desorb the extinguishing agent by heating or depressurization, and then liquefy and recover it through a condensation device.

[0115] Alternatively, the method by which the energy recovery submodule recovers the sprayed extinguishing agent may be related to the type of extinguishing agent. This application does not limit how the energy recovery submodule recovers the sprayed extinguishing agent.

[0116] Using the above method, the extinguishing agent after spraying can be recovered based on the energy recovery submodule, thereby realizing the energy recovery of the fire protection system and improving the reliability of the fire protection system.

[0117] For example, Figure 2A schematic diagram of the fire protection system architecture for another energy storage battery device provided in this application. (See diagram for example.) Figure 2 As shown, optionally, the fire protection system can be divided into four main modules: detection module, control module, fire extinguishing module, and communication module.

[0118] Each module is independently divided and designed, with standard, universal interfaces for equipment within each module to ensure compatibility across different manufacturers. Simultaneously, battery module-level and battery compartment-level detection modules require data fusion to implement fire protection system control strategies, while battery compartment-level detection modules and the Battery Management System (BMS) require data fusion to implement early warning and alarm strategies. A standard, universal communication protocol is designed, enabling one-time development without the need for multiple developments for different brands and communication protocols, thus achieving data fusion, transmission, and multi-device collaborative operation.

[0119] (1) Detection module: It adopts a distributed sensor array design and integrates multiple detection units such as temperature, smoke, and combustible gas. Through the standardized design of external communication interface and the consistent design of installation hole position, the modular structure realizes plug-and-play, and realizes early and accurate early warning of battery thermal runaway at the battery module level.

[0120] (2) Control Module: As the core decision-making unit of the system, it is equipped with the same access interface and communication protocol to receive data transmitted by detection modules from different manufacturers. It analyzes the fire level and range through intelligent algorithms and sends instructions to the fire extinguishing module and communication module. The fire alarm controller supports control logic programming from multiple manufacturers to meet the needs of different application scenarios.

[0121] (3) Fire extinguishing module: Designed as an independent fire extinguishing agent storage and spraying unit. Each fire extinguishing module is equipped with standardized interfaces and valve control devices, and fire extinguishing products from different manufacturers can be selected according to the actual needs of the energy storage system.

[0122] (4) System Communication: The system adopts a standardized communication protocol and an adaptive communication interface design. It can automatically identify the communication protocol of the connected devices and achieve seamless communication between devices from different manufacturers through protocol conversion. For example, when the detection equipment from manufacturer A and the control equipment from manufacturer B are connected to the system, the communication module can quickly complete the protocol conversion to ensure accurate data transmission.

This fire control method can be applied to fire protection systems as described in any of the foregoing embodiments. Figure 3 As shown, the fire control method for this energy storage battery device may include the following steps:

[0124] S301. The detection module collects fire characteristic data and transmits the fire characteristic data to the control module.

[0125] S302. When a fire is determined to exist based on the fire characteristic data, the control module generates a fire extinguishing control command and transmits the fire extinguishing control command to the fire extinguishing module and the communication module.

[0126] S303. Through the fire extinguishing module, in response to the fire extinguishing control command, a fire extinguishing operation is performed on the energy storage battery device.

[0127] S304. Through this communication module, in response to the fire extinguishing control command, data is exchanged with the target system.

Based on the fire extinguishing control command, the communication module of the fire protection system can achieve data interaction with the target system. By modularly designing the fire protection system and defining standardized interfaces, the compatibility and response efficiency of the fire protection system are improved.
