Description

[Technical Field]

[0001] This disclosure claims priority to a Chinese patent application filed with the China Patent Office on October 11, 2022, bearing application number 202211241728.4 and entitled "Self-detecting fire intake and exhaust control system and control method," the entire contents of which are incorporated herein by reference.

[0002] The present disclosure relates to the field of firefighting intake and exhaust control, for example, to a self-sensing firefighting intake and exhaust control system and method. [Background technology]

[0003] With the rapid development of energy storage, core safety has received increasing attention. Thermal runaway is the most serious risk to core safety, but overcharging and over-discharging are also the most common causes of core failure. With current technology, these issues cannot be completely avoided. While core temperature detection is widespread in existing energy storage systems, cooling is a passive measure that cannot prevent the generation of flammable gases, nor can cooling prevent explosions that occur when the concentration of flammable gases is too high.

[0004] Electrochemical energy storage uses chemical elements as energy storage media, and stores energy through chemical reactions or valence changes of the energy storage media. Electrochemical energy storage on the market mainly uses batteries as the energy carrier, and lithium batteries, represented by lithium iron phosphate, are one of the main choices in the energy storage industry, with very broad application prospects.

[0005] Under overcharge or thermal runaway conditions, lithium-ion batteries reach temperatures too high, causing the decomposition of the negative electrode SEI film, the decomposition of the positive electrode active material, and the oxidative decomposition of the electrolyte, resulting in the generation of large amounts of gas. Research has shown that CO2, CO, H2, C2H4, CH4, C2H6, and C3H6 are the seven most common gases in lithium-ion battery thermal runaway. The proportion of two gases, H2 (hydrogen) and CO (carbon monoxide), reaches over 70%.

[0006] Energy storage systems are constructed by assembling and stacking electrical cores (most commonly in the form of battery cabinets or containers) to achieve a certain energy storage capacity. The larger the battery capacity, the greater the number of electrical cores required, which increases the risk of thermal runaway. According to NFPA 855, the standard for installing stationary energy storage systems, the concentration of flammable gases should be less than 25% of the limit of the flammable gas concentration allowed in the space, so a fire exhaust system must be installed. When the concentration of flammable gases inside the container reaches a certain range, the fire exhaust system will be activated to expel the flammable gases from the container in a timely manner.

[0007] The mainstream solution on the market today is to install a combustible gas detector and a fire-fighting intake and exhaust system inside the energy storage container, and then link the two together. When the combustible gas detector detects that the concentration of combustible gas is too high, it will issue a warning signal, and after receiving (or indirectly receiving) the signal, the intake and exhaust system will start operating until the concentration of combustible gas reaches the standard value.

[0008] Currently, most technologies have the following issues: System open loop. Mainstream fire intake and exhaust systems on the market are mainly composed of automatic louvers, fans, and control panels (they all have the same intake and exhaust configuration). The control system can control the operation and shutdown of the system, but cannot monitor the operating status of the system. When the system is operating, if the fan stalls, the automatic louvers cannot open, or other control issues occur, the system cannot take relevant protective action. This can lead to equipment failure and, ultimately, more serious potential safety risks.

[0009] The inability to record on-site environmental information in real time. In an on-site application environment, if the fire intake and exhaust system operates, it may indicate a potential safety risk within the energy storage container, and the relevant operation and maintenance personnel will go to the site to troubleshoot. However, by the time the operation and maintenance personnel arrive, the intake and exhaust equipment may have already stopped and the fault may have been temporarily resolved. In this case, they will need to troubleshoot again to find the fault.

[0010] Low robustness. Fire intake and exhaust systems are not equipment that operates stably for a long period of time after installation, and in many cases, such equipment may not be used throughout the entire life cycle of the energy storage system. Whether the system can operate stably after being left unused for a long period of time is an uncontrollable risk point.

[0011] Single detection type. Most existing intake and exhaust devices can only detect flammable gases, but not the humidity level inside the container. Under most conditions, the inside of an energy storage container cannot be completely waterproof, and excessive humidity inside can pose a potential safety risk.

[0012] Low versatility: Most of the intake and exhaust systems applied to containers on the market are for one type of container, and different sizes and functions of the systems need to be customized for different containers, which not only makes installation and maintenance inconvenient but also increases the cost of use. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0030] Hereinafter, embodiments of the present disclosure will be described through specific examples, but those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed herein. The present disclosure can also be implemented or applied through other different specific embodiments, and various modifications or changes can be made to each detail in the present specification based on different perspectives and applications without departing from the spirit of the present disclosure. Furthermore, unless inconsistent, the following examples and features in the examples can be combined with each other.

[0031] It should be noted that the drawings provided in the following examples only roughly illustrate the basic concept of the present disclosure, and therefore only show units relevant to the present disclosure, and are not created according to the number, shape, and dimensions of the units when actually implemented. The type, number, and proportion of each unit when actually implemented can be freely changed, and the layout type of the units may also become more complex.

[0032] 1 to 3, the self-detecting fire intake and exhaust control system is applied to the detection of flammable gas in an energy storage container, and includes a gas detection module 11 mounted in the energy storage container 40, electrically connected to the control module 10, and for detecting the concentration of flammable gas in the energy storage container 40; an intake and exhaust module 12 mounted on the housing of the energy storage container 40, electrically connected to the control module 10, and for controlling the flow of gas in the energy storage container 40; and a control module 10 for controlling the operation of the gas detection module 11 and the intake and exhaust module 12, and for controlling the intake and exhaust module 12 to exhaust the flammable gas when the concentration of the flammable gas exceeds a predetermined concentration threshold.

[0033] The fire intake and exhaust control system further includes an operation detection module 121, which is disposed between the control module 10 and the intake and exhaust module 12 and is configured to monitor the working status of the intake and exhaust module 12 in real time. The control module 10, the gas detection module 11, the intake and exhaust module 12 and the operation detection module 121 constitute a closed-loop fire intake and exhaust control system, which realizes self-detection of system failures, thereby improving the reliability of the fire intake and exhaust control system.

[0034] An alarm module 16 is further provided on the housing of the energy storage container 40, and the control module 10 is further used to control the alarm module 16 to issue an alarm when an abnormal operation occurs in the intake and exhaust module 12. Under normal circumstances, the system does not operate, but when the gas detection module 11 detects that the concentration of flammable gas reaches a preset concentration threshold, the system is turned on and controls the intake and exhaust module 12 to start up. When the intake and exhaust module 12 operates, the current time, the concentration value of flammable gas, the control command signal of the control module 10, and the operating status of the intake and exhaust module 12 are all recorded and uploaded, thereby ensuring that on-site maintenance personnel can understand the system status data information in real time.

[0035] In one specific embodiment, the intake and exhaust module 12 is installed inside the energy storage container 40 and includes a louver device 1201 and a fan device (not shown), where the louver device 1201 and the fan device cooperate with each other to circulate air. Furthermore, the operation detection module 121 includes a louver detection sub-module (not shown) and a fan detection sub-module (not shown), where the louver detection sub-module determines the operating state of the intake and exhaust module 12 by detecting the louver state of the louver device 1201, and the fan detection sub-module determines the operating state of the intake and exhaust module 12 by detecting current information and rotation speed information of the fan device.

[0036] The louver detection submodule detects the movement distance of the louver link of the louver device 1201 using a position sensor to determine the open / closed state of the louver. Specifically, in application, the position sensors are provided above and below the louver link, and when the louver moves, they identify the distance between the louver link and the position sensor. If the distance between the louver link and the position sensor is smaller than a preset distance threshold, the position sensor identifies the louver as being in a closed state; if the distance between the louver link and the position sensor is greater than the preset distance threshold, the sensor identifies the louver as being in an open state. In actual use, the number, quantity, and locations of the position sensors are not limited to those mentioned in this embodiment. The number of position sensors may be one or more depending on the actual usage environment.

[0037] The fan detection submodule monitors changes in the current value and rotation speed of the fan device by installing a current sensor in the fan power cable and a rotation speed feedback conductor between the fan controller and the fan to determine whether the fan device is operating normally. Specifically, in application, when the system is running, the fan can feed back a rotation speed signal to the fan detection submodule via the rotation speed feedback conductor, and the current sensor feeds back a current signal to the fan detection submodule when the fan is running. The fan detection submodule determines whether the fan is operating normally based on the fan rotation speed and the fan current. When the fan is operating normally, if the resistance of the blades is high, the fan rotation speed is low and the fan current is high. On the other hand, if the fan stalls, the current will be at its maximum. The fan detection submodule determines whether the fan is operating normally based on preset rotation speed and current thresholds. If a single detection value is too high or too low, or if the current and rotation speed do not match, the fan detection submodule determines that the fan is faulty.

[0038] In one specific embodiment, the self-detecting fire intake and exhaust control system further includes a temperature detection module 13, which is installed in the energy storage container 40 and electrically connected to the control module 10 for monitoring the environmental temperature of the energy storage container 40 in real time. If the environmental temperature monitored by the temperature detection module 13 does not exceed a preset temperature threshold and the concentration of flammable gas monitored by the gas detection module 11 exceeds a preset concentration threshold, the control module 10 controls the intake and exhaust module 12 to start operating and exhaust the flammable gas. A fire extinguishing module 15 is further provided, which is installed in the energy storage container 40 and connected to the control module 10. If the temperature detection module 13 detects an abnormality, the control module 10 controls the fire extinguishing module 15 to start operating and reduce the temperature or extinguish the fire. When the environmental temperature monitored by the temperature detection module 13 exceeds a preset temperature threshold and the concentration of flammable gas monitored by the gas detection module 11 exceeds a preset concentration threshold, the control module 10 controls the fire extinguishing module 15 to start operating, reducing the temperature or extinguishing the fire.

[0039] The humidity detection module 14 is installed in the energy storage container 40 and electrically connected to the control module 10, and is used to monitor the environmental humidity of the energy storage container 40 in real time; when the environmental humidity monitored by the humidity detection module 14 exceeds a preset humidity threshold, the control module 10 controls the intake / exhaust module 12 to start operation and perform ventilation.

[0040] In one specific embodiment, the self-detecting fire ventilation control system further includes a communication module 20 connected to the control module 10. The control module 10 receives control commands from the EMS system 30 through the communication module 20 and transmits status information of the energy storage container to the EMS system 30 and the cloud. The control module 10 is further configured to control the alarm module 16 to issue an alarm when a communication abnormality occurs in the communication module 20. The control commands include an operation command for controlling the ventilation module 12 and an operation command for controlling the gas detection module 11, the motion detection module 121, the temperature detection module 13, and / or the humidity detection module 14. The status information includes the concentration of the flammable gas, the temperature in the energy storage container 40, the humidity in the energy storage container 40, and the operating status of the ventilation module 12. Furthermore, the EMS system 30 can control the ventilation module 12. If the concentration of the flammable gas monitored by the gas detection module 11 does not exceed a predetermined concentration value, the EMS system 30 can control the opening and closing of the ventilation module 12.

[0041] If the intake and exhaust module 12 is unable to operate normally, the control module 10 issues an alarm through the alarm module 16 and also reports the status information to the EMS system 30 in a timely manner. The alarm module 16 issues different alarm methods according to different types of failure, so that on-site maintenance personnel can easily determine the type of failure according to the alarm method of the alarm module 16 without having to look at the failure status information reported by the EMS system 30.

[0042] In one embodiment, the communication module 20 transmits data using the TCPIP protocol. Specifically, in application, the higher-level management system actively communicates with the fire ventilation control system to detect whether an abnormality exists in the system's operation in the form of a heartbeat. If the system fails to respond normally to the heartbeat information after a certain period of time, it is determined that the system communication is abnormal. The fire ventilation control system then transmits the fault information to the higher-level management system.

[0043] In one specific embodiment, the fire intake and exhaust control system is further provided with an operation indicator (not shown), which displays normally when the system is operating normally, and indicates when there is a problem with the system such as a crash.

[0044] In one specific embodiment, the control module 10 is provided with a timing detection function. The control module 10 opens and closes the intake and exhaust module 12 within a certain time period. When the louver device 1201 and the fan device are operating, the control module 10 monitors the status information of each through the operation detection module 121. If an abnormality is detected (for example, the automatic shutter does not open, the intake and exhaust equipment is stalled, or an abnormal input / output signal is detected), the control module 10 records the status of the intake and exhaust control system at that time, transmits the data information to the EMS system 30, and issues an alarm through the alarm module 16. This avoids the problem that the louver device 1201, the fan device, and the system information transmission may malfunction if not used for a long period of time, and increases safety and reliability.

[0045] In one specific embodiment, the louver device 1201 includes an intake louver 12011 and an exhaust louver 12012, and the intake louver 12011 is provided on the side of the housing of the energy storage container 40, close to the bottom, and the exhaust louver 12012 is provided on the top or side of the housing of the energy storage container 40, relatively close to the top.

[0046] Specifically, in application, the most basic function of the fire ventilation control system is to exhaust flammable gases inside the energy storage container 40. The flammable gases present inside the energy storage container 40 mainly include CO2, CO, H2, C2H4, CH4, C2H6, and C3H6, with H2 and CO being the gases that are primarily generated. Because the proportion of these two gases reaches 70% or more and their densities are lower than that of air, when these two gases are generated, they accumulate in the upper layer of the energy storage container 40. Therefore, the exhaust louver 12012 is installed on the top of the energy storage container 40, and the intake louver 12011 is installed on the bottom of the energy storage container 40. A corresponding gas detection module 11 is also installed in the upper part of the container.

[0047] Since it is possible for the energy storage container 40 to have a separate battery compartment 41 to prevent water from entering the location where the battery pack is installed, the exhaust louver 12012 may be attached to the side of the battery compartment 41 at a position corresponding to the housing of the energy storage container 40.

[0048] In one specific embodiment, the number of input / output ports and fan devices of the louver device 1201 can be customized as needed, and the more input / output ports there are, the larger the volume of the control module 10 will be, so that it can be installed independently inside or outside the energy storage container 40; and the fewer input / output ports there are, the smaller the volume of the control module 10 will be, so that it can be installed inside the louver device 1201 or the fan device.

[0049] Referring to FIG. 4, the present disclosure further provides a control method for a self-detecting fire intake and exhaust control system, the control method comprising: Step S10: obtaining real-time data of the concentration of combustible gas collected by the gas detection module; Step S20: If the concentration of the combustible gas is higher than the preset concentration threshold, the control module sends a control command to the intake and exhaust module to control the intake and exhaust module to exhaust the combustible gas; Step S30: Obtaining real-time data of the working state of the intake and exhaust module collected by the operation detection module; Step S40 includes issuing an alarm through an alarm module when an abnormal situation occurs in the working state.

[0050] In one specific embodiment, the control method further includes steps S21 to S22. In step S21, the real-time data of the ambient temperature collected by the temperature detection module is obtained. If the ambient temperature is lower than the preset temperature threshold and the concentration of the flammable gas is higher than the preset concentration threshold, the control module sends a control command to the intake and exhaust module to control the intake and exhaust module to discharge the flammable gas. If the ambient temperature is higher than the preset temperature value, the control module sends a control command to the fire extinguishing module to control the fire extinguishing module to lower the temperature or extinguish the fire, and issues an alarm through the alarm module. In step S22, the real-time data of the environmental humidity collected by the humidity detection module is obtained, and if the environmental humidity is higher than the preset humidity threshold, the control module sends a control command to the intake and exhaust module to control the intake and exhaust module to circulate air.

[0051] As described above, the technical effects of the present disclosure are as follows: That is, the fire intake and exhaust control system is a closed-loop system composed of a control module, a detection module, an intake and exhaust module, and an operation detection module, and has higher reliability than currently available intake and exhaust systems. The system records environmental factors of the energy storage container in real time, and records environmental conditions such as the temperature, gas concentration, and humidity of the energy storage container regardless of whether the system is operating. When the intake and exhaust module is operating, maintenance personnel can search for the status of the corresponding intake and exhaust module according to the operating time, which makes it easy to determine a fault condition in advance. Even if the fault information is not available in a timely manner during various emergency situations, it does not affect the subsequent fault diagnosis. The system performs self-checks at fixed time intervals, greatly increasing the reliability of the system. Currently available intake and exhaust systems lack this function, and if the device is left unused for a long period of time, the system will not be operated for a long period of time, and problems will not be detected in a timely manner. If the equipment fails to operate when the system needs to operate, it may pose a greater risk to the energy storage container. Compared with existing air intake and exhaust systems, the disclosed system adds a communication module that uploads environmental information of the energy storage container and operating information of the air intake and exhaust module to the cloud, allowing maintenance personnel to monitor the internal connection status of the energy storage container at any time, providing more reliable protection for the safety of the energy storage container, and also includes a fire extinguishing module that can timely cool the energy storage container or extinguish a fire to prevent greater losses. In addition, the system is applicable to various types of containers and has higher compatibility.

[0052] The present disclosure further provides a control method for a self-detecting fire intake and exhaust control system, which enables control of the intake and exhaust module and real-time monitoring of the operating status of the intake and exhaust module, thereby making the system operate more stably and reliably.

[0053] The fire intake and exhaust control system of the present disclosure is safer, more reliable, more versatile, and more cost-effective than existing intake and exhaust equipment currently on the market.
