Description

Technical Field

[0001] The present application relates to the field of fire protection technology of new energy, and in particular to an energy storage container fire protection system and an energy storage container. Background Art

[0002] Energy storage containers typically contain numerous battery cells. During the charging and discharging process, these cells can experience thermal runaway due to overcharging, over-discharging, short circuits, and other factors, potentially leading to fires. Therefore, fire safety in energy storage containers is crucial, and they require effective firefighting systems to prevent and respond to potential fires.

[0003] Currently, the fire protection system of energy storage containers has problems with complex design and high costs. These problems are mainly manifested in that each battery pack needs to reserve a fire communication interface, install a control valve, and connect the lines to the fire alarm controller, which not only increases the complexity of the system, but also significantly increases the cost of installation and maintenance. In addition, since each battery pack requires an independent fire control unit, this design may increase the difficulty of maintenance in actual operation. In the event of a fire, the fire extinguishing efficiency of the entire system may be affected by the failure of the control unit. Therefore, how to simplify the structural design of the fire protection system, reduce costs, and at the same time maintain or improve fire extinguishing efficiency and reliability is a key technical problem that needs to be solved in this field.

Another purpose of this application is to provide an energy storage container.

[0005] To achieve the above-mentioned objectives, the present application provides an energy storage container fire protection system, comprising a fire extinguishing device, a first detection device and a fire alarm controller provided in the energy storage container, wherein the first detection device is used to be directly connected to the battery management system in the energy storage container via a dry contact method, and the fire alarm controller is used to communicate with the battery management system. The fire alarm controller is used to control the fire extinguishing device to achieve fire extinguishing based on a combination of one or more of the monitoring information of the first detection device and the monitoring information of the battery management system.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] Please refer to Figure 1 , Figure 1 Schematic diagram of the energy storage container fire protection system provided in an embodiment of the present application.

[0032] In a first specific embodiment, the energy storage container fire protection system 100 provided in the embodiment of the present application mainly includes a fire extinguishing device 1, a first detection device 2 and a fire alarm controller 3 arranged in the energy storage container. The first detection device 2 is used to be directly connected to the battery management system 4 in the energy storage container through a dry contact method. The fire alarm controller 3 is used to communicate with the battery management system 4. The fire alarm controller 3 is used to control the fire extinguishing device 1 to achieve fire extinguishing according to the combination of one or more of the monitoring information of the first detection device 2 and the monitoring information of the battery management system 4.

[0033] It should be noted that dry contact direct connection is a signal transmission method commonly used in electrical control systems. It transmits signals by closing or opening two contacts, and does not directly involve the transmission of power current. This method is characterized by simplicity, low current, and can be applied to a variety of voltage systems. In the energy storage container fire protection system, dry contact direct connection is used to connect the first detection device 2 and the battery management system 4, so that the first detection device 2 can send a signal directly to the battery management system 4. For example, when smoke or abnormal temperature rise is detected, the contact closes, thereby transmitting an alarm signal. This connection method reduces the system's wiring requirements, simplifies the installation and maintenance process, and improves the system's reliability and response speed, which helps to achieve rapid fire detection and response. Through dry contact direct connection, the energy storage container fire protection system can more efficiently prevent and control fires and ensure the safe operation of the energy storage container.

[0034] In the field of fire safety for energy storage containers, the main challenges in the prior art are the complex design, high cost, and difficult maintenance of fire protection systems. These issues can affect the firefighting efficiency and reliability of the system in the event of a fire. To address these issues, this application proposes a new fire protection system 100 for energy storage containers.

[0035] The core of this system lies in simplifying the structural design of the fire protection system. By directly connecting the first detection device 2 to the battery management system 4 via dry contacts, the need for additional communication interfaces and wiring is reduced. This design directly transmits the detection device signals to the battery management system 4, thereby reducing system complexity. Simultaneously, the fire alarm controller 3 communicates with the battery management system 4 and receives monitoring information from it, such as battery temperature and status. This information is crucial for fire prevention, risk assessment, and firefighting strategy development.

[0036] The fire alarm controller 3 comprehensively determines the likelihood and severity of a fire based on the monitoring information from the first detection device 2 and the battery management system 4. Once a fire risk is detected, the controller immediately activates the fire extinguishing device 1, achieving rapid response and effective fire extinguishing. This intelligent control strategy based on real-time data not only improves fire extinguishing efficiency but also enhances system reliability.

[0037] Combined with the above structure and process description, it can be seen that the energy storage container fire protection system 100 has at least the following beneficial effects: the energy storage container fire protection system 100 simplifies the structural design of the fire protection system, reduces costs, and improves the fire extinguishing efficiency and system reliability by directly connecting the first detection device 2 and the battery management system 4 with dry contacts, and the fire alarm controller 3 comprehensively monitors the information to control the fire extinguishing device 1.

[0038] It should be noted that the energy storage container fire protection system 100 provided in this application is applicable to energy storage containers, and in particular, the energy storage container fire protection system 100 and the battery management system 4 in the energy storage container form a battery container fire extinguishing system solution. This embodiment does not limit the number of battery PACKs in the energy storage container. Generally, there can be one or more battery PACKs in an energy storage container. In this embodiment, the first detection device 2 in the energy storage container fire protection system 100 is directly connected to the battery management system 4 in the battery PACK via a dry contact method. At this time, the fire alarm controller 3 controls the fire extinguishing device 1 to achieve a PACK-level fire extinguishing situation. In particular, the first detection device 2 is provided in the battery PACK.

[0039] In addition, the relevant configurations of the fire extinguishing device 1 and the fire alarm controller 3 may refer to the prior art and are not limited in this embodiment.

[0040] Please refer to Figure 2 and Figure 3 , Figure 2 A top view of the energy storage container fire protection system and energy storage container provided in an embodiment of the present application, Figure 3 A top view of the energy storage container fire protection system and energy storage container provided in an embodiment of the present application.

[0041] In some embodiments, the first detection device 2 includes a first detector 21, which is used to monitor combustible gas information. The first detector 21 is directly connected to the battery management system 4 through a dry contact method.

[0042] In this embodiment, the design of the first detection device 2 focuses on monitoring flammable gas information within the energy storage container, which is a key factor in fire prevention and timely response. The first detector 21 is the core component that realizes this function. It is specifically designed to sense and identify flammable gases that may cause fires, such as carbon monoxide or other flammable gases. By directly connecting the first detector 21 to the battery management system 4 via dry contacts, the system can ensure that when flammable gas is detected, the signal is quickly transmitted to the battery management system 4, triggering further alarms or fire-fighting measures.

[0043] It's important to emphasize that the use of dry contact connections means the output signal from the first detector 21 is passive, transmitting status information only through a simple closing or opening. This approach not only simplifies circuit design but also reduces the risk of electrical failure. Furthermore, this connection method improves system response speed, as signal transmission does not rely on any external power source, ensuring immediate response to potential fire threats. In this way, the energy storage container fire protection system 100 effectively improves the safety of the energy storage container's internal environment and reduces the risk of fire.

[0044] Specifically, the energy storage container contains several battery packs, each of which contains several battery cells, which can be lithium iron phosphate cells. The battery management system 4, abbreviated as BMS, consists of three management modules: the BMU (slave control module), the BCMU (master control module), and the BAMS (display and control module). The BMU collects and transmits voltage and temperature data within the battery pack; the BCMU aggregates temperature and voltage data collected by the BMU across the entire battery cluster and performs fault analysis and calculations; and the BAMS provides unified management, control, and display for the battery cluster within the entire battery container.

[0045] In this embodiment, a first detection device 2 is configured within the battery pack. Its communication signal is converted to dry contact and directly connected to the battery pack's BMU module. The signal is then transmitted to the BAMS through the BMU, and the BAMS then communicates with the fire alarm controller 3. Because the first detection device 2 transmits signals to the BMU via dry contact, shared communication with the BMU reduces wiring requirements.

[0046] In some embodiments, the fire alarm controller 3 is used to control the fire extinguishing device 1 to extinguish fire according to the combustible gas information monitored by the first detector 21 and the battery core temperature information monitored by the battery management system 4.

[0047] In this embodiment, the fire alarm controller 3 is responsible for integrating information from various sources to make fire-extinguishing decisions. Specifically, the fire alarm controller 3 receives and analyzes the combustible gas information detected by the first detector 21 and the battery cell temperature information monitored by the battery management system 4. For example, if the first detector 21 detects an abnormal combustible gas concentration and the battery management system 4 reports that the battery cell temperature exceeds a safe threshold, the fire alarm controller 3 will use this information as a basis for determining the fire risk.

[0048] The fire alarm controller 3 determines whether to activate the fire extinguishing device 1 based on preset logic and parameters, such as when the combustible gas concentration exceeds a preset value or when the battery cell temperature continuously rises to a specific level. Once the fire alarm controller 3 confirms the existence of a fire risk, it immediately sends a control signal to the fire extinguishing device 1, triggering the fire extinguishing process.

[0049] In some embodiments, the fire alarm controller 3 is used to control the fire extinguishing device 1 to extinguish a fire when the combustible gas information exceeds a preset value and the temperature of at least two battery cells in the battery cell temperature information exceeds a preset value.

[0050] In this embodiment, the fire alarm controller 3 is configured to trigger the fire extinguishing device 1 only when two key conditions are simultaneously met. First, the first detector 21 monitors the combustible gas inside the energy storage container. If the detected combustible gas concentration exceeds a preset safety value, this indicates a potential fire risk. Second, the battery management system 4 continuously monitors the temperature of the battery cells. If the temperature of at least two battery cells exceeds a preset threshold, this may indicate battery overheating and the risk of thermal runaway.

[0051] Only when both conditions are met will the fire alarm controller 3 issue a command to activate the fire extinguishing device 1 for firefighting. This design provides a more cautious and safe fire response mechanism, ensuring that the fire extinguishing process is initiated only when a high fire risk exists, thus preventing fires from occurring in advance. This logical judgment effectively avoids false alarms and unnecessary firefighting operations, while ensuring a swift and effective response when a real fire risk arises.

[0052] PACK-level fire extinguishing and compartment-level fire extinguishing are two fire extinguishing strategies for fires of different scales inside energy storage containers.

[0053] Please refer to Figure 4 , Figure 4 This is a flow chart of PACK-level fire extinguishing provided in an embodiment of the present application.

[0054] In some embodiments, the fire alarm controller 3 is configured to control the fire extinguishing device 1 to implement PACK-level fire extinguishing based on a combination of one or more of the monitoring information from the first detection device 2 and the monitoring information from the battery management system 4. Specifically, when the combustible gas information exceeds a preset value and the temperature of at least two battery cells in the battery cell temperature information exceeds a preset value, the fire alarm controller 3 controls the fire extinguishing device 1 to implement PACK-level fire extinguishing.

[0055] Pack-level fire suppression means that when the fire alarm controller detects a fire risk in a specific battery pack area, the system will initiate fire suppression operations in that specific area. This localized fire suppression method aims to quickly locate and extinguish the initial fire, prevent the fire from spreading to other areas, and minimize the impact on the entire energy storage container.

[0056] Please refer to Figure 5 , Figure 5 A flowchart of cabin-level fire extinguishing provided in an embodiment of the present application.

[0057] In some embodiments, the energy storage container fire protection system 100 further includes a second detection device 5 , which is communicatively connected to the fire alarm controller 3 ; the fire alarm controller 3 is configured to control the fire extinguishing device 1 to achieve cabin-level fire extinguishing according to the monitoring information of the second detection device 5 .

[0058] Compartment-level fire suppression is a fire suppression measure implemented when a fire spreads to the entire energy storage container or multiple PACK areas. At this point, the fire alarm controller initiates a compartment-wide fire suppression program, releasing extinguishing media throughout the compartment to control and extinguish the larger fire. Compartment-level fire suppression is equivalent to a comprehensive response, aiming to take swift action to protect the safety of the entire energy storage container before the fire gets out of control.

[0059] In some embodiments, the second detection device 5 includes a second detector 51, which is used to monitor smoke information.

[0060] In some embodiments, the second detection device 5 includes a third detector 52, which is used to monitor combustible gas information.

[0061] In some embodiments, the second detection device 5 includes a fourth detector 53, which is used to monitor temperature information.

[0062] In the energy storage container fire protection system, the second detection device 5 enhances the fire monitoring capability by integrating multiple detectors. The second detector 51 is specifically used to monitor smoke and can issue an alarm in time by detecting the presence of smoke at the early stage of a fire. The third detector 52 is responsible for monitoring the concentration of combustible gases, which helps to identify fire risks that may be caused by leaks or abnormal chemical reactions. The fourth detector 53 is used to monitor temperature changes and can sense abnormal increases in ambient or equipment temperature, which is a common sign before a fire occurs. These detectors work together to provide the fire alarm controller 3 with comprehensive environmental monitoring data, enabling it to accurately judge the fire situation and take appropriate fire extinguishing measures. Through this diversified monitoring method, the system can more effectively identify and respond to fire hazards in energy storage containers, thereby improving overall fire safety.

[0063] In some embodiments, the fire extinguishing device 1 includes a fire extinguishing pipeline 11 and a gas tank 12 that are connected to each other, and the gas tank 12 is filled with perfluorohexanone gas.

[0064] In this embodiment, the fire extinguishing device 1 comprises a fire extinguishing line 11 and a gas tank 12, which is filled with perfluorohexanone gas. This fire extinguishing agent is quickly delivered to the fire source through the fire extinguishing line 11, effectively extinguishing the fire. Due to its clean and low-toxic properties, it is suitable for use in enclosed spaces, minimizing damage to equipment.

[0065] In some cases, the fire extinguishing pipeline 11 includes a gas fire extinguishing main pipe 111, a gas fire extinguishing compartment-level pipe 112, a water fire fighting pipe 113, and a fire extinguishing branch pipe 114. The gas fire extinguishing main pipe 111 is the main pipeline, responsible for transporting the fire extinguishing agent from the gas tank 12 to other branch pipes. The gas fire extinguishing compartment-level pipe 112 is a fire extinguishing pipeline specifically used for the entire energy storage container compartment, ensuring that the fire extinguishing agent can cover the entire compartment space. The water fire fighting pipe 113 is used to transport water-based fire extinguishing agents, which are suitable for different types of fires. The fire extinguishing branch pipe 114 may be used to distribute the fire extinguishing agent to specific areas or equipment to achieve more refined fire extinguishing control. This subdivision of the pipeline design enables the fire extinguishing system to flexibly select and adjust the fire extinguishing strategy according to different fire conditions and locations, thereby improving fire extinguishing efficiency and safety.

[0066] In addition, the arrangement of fire sprinklers and control valves such as cluster control valves and compartment control valves can refer to the existing technology.

[0067] The present application also provides an energy storage container, including a container body 6 , wherein the container body 6 is provided with the above-mentioned energy storage container fire protection system 100 .

[0068] The energy storage container should have all the beneficial technical effects of the above-mentioned energy storage container fire protection system 100, which will not be described in detail here.

[0069] In some cases, the second detection device 5 is set on the top of the box 6, and the two groups of second detection devices 5 are distributed front to back, and the second detector 51, the third detector 52, and the fourth detector 53 in each group of second detection devices 5 are distributed left to right. In addition, the top of the box 6 is also provided with an explosion vent 601.

[0070] In some cases, the side of the box 6 is provided with an air inlet 602, an explosion-proof fan 603, a deflation indicator light 604, an audible and visual alarm 605, an alarm bell 606, an emergency start and stop button 607, a manual alarm button 608, a fan switch 609, a combustible gas concentration display 610, and a water fire-fighting interface 611.

[0071] The side air inlet 602 allows air to circulate, helping to maintain a stable environment within the box. The explosion-proof fan 603 is used to provide ventilation when combustible gas or smoke is detected to reduce the risk of explosion or quickly remove harmful gases.

[0072] The deflation indicator light 604 and the audible and visual alarm 605 provide visual and audible warnings when a fire or other emergency is detected, while the alarm bell 606 sounds a loud bell to alert personnel. The emergency start and stop button 607 and the manual alarm button 608 allow operators to respond quickly in an emergency, respectively stopping all operations or triggering the alarm.

[0073] The fan switch 609 is used to manually control the explosion-proof fan 603, while the combustible gas concentration display 610 displays the concentration of combustible gas in the box in real time to help monitor environmental safety. The water firefighting interface 611 facilitates the connection of a water-based firefighting system so that water can be used for firefighting when necessary.

[0074] exist Figure 4 In the PACK-level fire extinguishing process, the first detector 21 (the CO / VOC detector in the figure) monitors the combustible gas information inside the energy storage container. The first detector 21 transmits information to the battery management system 4 (the BMS battery management system in the figure) through dry contacts. The battery management system 4 monitors the temperature of the battery cells in the battery PACK. The battery management system 4 transmits information to the fire alarm controller 3 through CAN / 485. The fire alarm controller 3 analyzes this information and determines whether there is a fire risk.

[0075] If the fire alarm controller 3 determines a level 1 fire risk, it activates the alarm. If it determines a level 2 fire risk, it also activates the alarm and sounds the alarm. This process can also be triggered manually. If it determines a level 3 fire risk, the fire alarm controller 3 activates the alarm and sounds the alarm. It also issues linkage signals, such as shutting down the smoke exhaust fan, air conditioning, tripping the PCS, and tripping the battery cluster circuit breaker. It also performs fire extinguishing operations, such as delaying 20 seconds (adjustable), opening the corresponding cluster control valve, activating the fire cylinder, and spraying the fire (≥2 times).

[0076] It can also be manual control, such as emergency / manual start, which causes the fire alarm controller 3 to execute the process of level 3 fire risk, such as emergency / manual stop, which stops the operation being executed.

[0077] exist Figure 5 In the cabin-level fire extinguishing process, the second detector 51, the third detector 52, and the fourth detector 53 (smoke, combustible gas, and temperature in the figure) monitor the smoke, combustible gas, and temperature information in the energy storage container. The fire alarm controller 3 receives the monitoring information from the second detector 51, the third detector 52, and the fourth detector 53, and analyzes the information to determine whether there is a fire risk.

[0078] The fire alarm controller 3 can be set to trigger with a single signal. When a fire risk is detected, the alarm is activated, along with an audible and visual alarm. This process can also be triggered manually. The fire alarm controller 3 can also be set to trigger with a combination of temperature and any other signal. When a fire risk is detected, the alarm is activated, along with an audible and visual alarm. It also issues linkage signals, such as shutting down the smoke exhaust fan, air conditioning, stopping the PCS, or tripping the battery cluster circuit breaker. It also initiates fire extinguishing operations, such as delaying for 20 seconds (adjustable), opening the cabin control valve, activating the gas cylinder, and spraying the fire.

[0079] It can also be manual control, such as emergency / manual start, which causes the fire alarm controller 3 to execute the fire risk process, such as emergency / manual stop, which stops the operation being executed.
