Description

Technical Field

[0001] The present invention relates to the technical field of energy storage ventilation devices, and particularly to a control method and system for an energy storage ventilation device. Background Art

[0002] An energy storage ventilation device is a supporting ventilation equipment to ensure the safe and stable operation of an energy storage system. It is suitable for various energy storage power stations such as lithium battery energy storage and flow battery energy storage, as well as application scenarios such as energy storage containers and energy storage cabinets. It can quickly adjust the temperature and humidity in the cabin, avoid faults such as thermal runaway and short circuit of the battery due to high temperature and high humidity, and can timely discharge harmful gases such as hydrogen and carbon monoxide generated during the charge and discharge process of the battery, preventing safety hazards such as explosion and combustion caused by gas accumulation, and providing a reliable environmental guarantee for the long-term and safe operation of the energy storage system.

[0003] At present, the control modules supporting conventional energy storage ventilation devices on the market are not only relatively large in size, making it difficult to adapt to compact installation scenarios such as energy storage containers and energy storage cabinets, but also require an additional external independent control cabinet to achieve operation regulation. This not only increases the overall installation space occupancy, wiring complexity and equipment input cost of the system, but also increases the workload of later maintenance; and most of the control methods can only achieve the basic functions of starting and stopping the fan. When the ventilation device has operation faults such as fan jamming and air duct blockage, or when there is a communication disconnection between the control module and the main controller of the energy storage system, the reporting of fault signals and the feedback of disconnection status often have obvious delays, and it is extremely easy to cause problems such as out-of-control of the temperature in the cabin and accumulation of harmful gases due to untimely handling of abnormal states, presenting an out-of-control risk. Summary of the Invention

[0007] In some embodiments, the status transmission data corresponding to the gas detector includes a hazard alarm signal and a hazard resolution signal. After detecting a hazard, the gas detector sends a hazard alarm signal to the ventilation control module. After detecting that the hazard has ended, the gas detector sends a hazard resolution signal to the ventilation control module.

[0008] In some embodiments, the status transmission data corresponding to the exhaust device and the air intake device includes a normal operation signal and a fault status signal.

[0009] In some embodiments, the status transmission data corresponding to the manual button includes a ventilation shutdown signal, which is sent when the manual button is pressed.

[0010] In some embodiments, the control node signals output by the ventilation control module include power signals, on signals, off signals, fault signals, and battery signals. The ventilation control module outputs power signals, on signals, and / or fault signals when it detects that the exhaust device and the air intake device are on, and outputs power signals, off signals, and / or fault signals when it detects that the exhaust device and the air intake device are off.

[0011] In some embodiments, the exhaust and intake devices are turned on when the gas detector detects that the concentration of combustible gas has reached an alarm threshold, and the exhaust and intake devices are turned off when the gas detector detects that the concentration of combustible gas has not reached the alarm threshold, a manual button sends a signal to turn off the ventilation, or the battery management system sends a signal to turn off the ventilation.

[0012] In a second aspect, the present invention also provides a control system for an energy storage ventilation device, for operating the energy storage ventilation device control method as described in the first aspect, the control system comprising: The ventilation control module is used to acquire status transmission data corresponding to gas detectors, exhaust devices, air intake devices, and manual buttons, and output control node signals. The exhaust system is used to receive signals from the control node to control the exhaust process, to discharge combustible gas when an emergency occurs, and to shut off the exhaust after the emergency ends. The air intake device is used to receive signals from the control node to control the air intake process, draw in fresh air when an emergency occurs, and shut off the air intake after the emergency ends. Gas detectors are used to detect the concentration of combustible gases, send an alarm signal after a hazard occurs, and send a hazard clearance signal after the hazard ends. The manual button is used to send a signal to shut off ventilation when pressed. The controller module is used to receive signals from the control node.

[0013] In some embodiments, the ventilation control module is integrated inside the exhaust device. The ventilation control module is electrically connected to the exhaust device, the air intake device, the gas detector, the manual button, and the controller module. The ventilation control module is provided with a power transmission interface, a control node interface, and a communication signal interface.

[0015] The present invention has the following beneficial effects: 1. In this invention, the ventilation control module continuously acquires the status transmission data corresponding to the gas detector, exhaust device, air intake device, and manual button based on the configured transmission address data. After the gas detector detects a hazard, it sends a hazard alarm signal to the ventilation control module. The ventilation control module outputs a control node signal to control the exhaust device and air intake device to open for ventilation. When the gas detector detects that the hazard has ended, it sends a hazard clearance signal. When the manual button is pressed or the battery management system sends a shutdown signal, the ventilation control module sends a ventilation shutdown signal. The ventilation control module outputs a control node signal to control the exhaust device and air intake device to close for ventilation. 2. The ventilation control module of this invention is small in size and can be directly installed in conventional energy storage ventilation devices.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This application provides a control method and system for an energy storage ventilation device, solving the problem that conventional control modules for energy storage ventilation devices in the prior art are not only bulky and difficult to adapt to compact installation scenarios such as energy storage containers and cabinets, but also require an additional external independent control cabinet for operation and control. This increases the overall installation space occupation, wiring complexity, and equipment investment cost of the system, as well as the workload of later maintenance. The reporting of fault signals and feedback of disconnection status often have significant delays, which can easily lead to problems such as uncontrolled temperature inside the compartment and accumulation of harmful gases due to untimely handling of abnormal states. In contrast, the ventilation control module of this application is small in size and can be directly installed in conventional energy storage exhaust devices. It can also be linked with the battery management system of the fire extinguishing system, supports high-speed interface communication, and can remotely start the ventilation device via serial communication and monitor the operating status of the ventilation device online in real time, effectively improving the reliability of the energy storage fire protection system.

[0020] Please refer to the following examples for details: Reference Figures 1-5 An embodiment of the energy storage ventilation device control method provided by the present invention includes the following specific structure: S100, configured with the transmission address corresponding to the operating status data of gas detector 2, exhaust device 3, air intake device 4 and manual button 5; S200, the ventilation control module 1 continuously acquires the status transmission data corresponding to the gas detector 2, exhaust device 3, air intake device 4 and manual button 5 based on the configured transmission address data, and outputs control node signals; S300, the exhaust device 3 and the air intake device 4 receive the corresponding output control node signals to instruct the corresponding exhaust device 3 and air intake device 4 to respond to the control node signals.

[0021] For example, the operating status data transmission addresses of the gas detector 2, exhaust device 3, air intake device 4 and manual button 5 are pre-configured. This address serves as the unique identifier for data interaction between each device and the ventilation control module 1, ensuring that the status information of various devices and control commands are accurately matched during transmission, thus avoiding signal confusion or false triggering of commands. Based on the configured transmission address data, the ventilation control module 1 continuously acquires the operating status transmission data fed back by the gas detector 2, exhaust device 3, air intake device 4 and manual button 5 through a preset communication link, and performs real-time analysis, verification and logical judgment on these data, and generates and outputs the corresponding control node signal according to the judgment result. The exhaust device 3 and the air intake device 4 receive the control node signals output by the ventilation control module 1 in real time, and use them to start, stop and switch operating modes. They instruct the corresponding exhaust device 3 and air intake device 4 to respond quickly to the control node signals and complete a series of actions such as starting, stopping and speed adjustment, thereby realizing gas replacement and environmental regulation in the energy storage compartment.

[0022] Please continue reading. Figure 2 In this embodiment, step S100 includes: S110, configured with the transmission addresses corresponding to multiple sets of gas detectors 2, exhaust devices 3, air intake devices 4, and manual buttons 5; S120 sends the operating status data corresponding to each group of gas detectors 2, exhaust devices 3, air intake devices 4, and manual buttons 5 to the ventilation control module 1 via the serial bus.

[0023] For example, to meet the actual monitoring and control needs of the energy storage system, multiple sets of gas detectors 2, exhaust devices 3, air intake devices 4, and manual buttons 5 are configured with corresponding transmission addresses. The transmission address of each set of devices is unique, which can adapt to the environmental monitoring and ventilation control needs of multiple areas and multiple points in the energy storage compartment, effectively improving the system's compatibility and scalability.

[0024] The operating status data corresponding to each group of gas detectors 2, exhaust devices 3, air intake devices 4, and manual buttons 5 are accurately and in real time sent to the ventilation control module 1 via a serial bus. The serial bus communication method can ensure low latency and high reliability of data transmission, meeting the timeliness requirements of the ventilation system for data interaction.

[0025] In some embodiments, the status transmission data corresponding to the gas detector 2 includes a hazard alarm signal and a hazard elimination signal; wherein, when the gas detector 2 detects that the concentration of combustible gas has exceeded a preset safety threshold, it determines that a hazard has occurred and immediately sends a hazard alarm signal to the ventilation control module 1; when the gas detector 2 detects that the concentration of combustible gas has fallen back to within the safety threshold range, it determines that the hazard has ended and promptly sends a hazard elimination signal.

[0026] In some embodiments, the status transmission data corresponding to the exhaust device 3 and the air intake device 4 includes normal operation signals and fault status signals. When the fan speed, duct pressure, equipment operating temperature and other parameters of the exhaust device 3 and the air intake device 4 are all within the preset normal range, they will continuously send normal operation signals to the ventilation control module 1. When the exhaust device 3 and the air intake device 4 experience abnormal conditions such as fan jamming, duct blockage, or motor overload, they will immediately send fault status signals so that the control module can promptly grasp the equipment operating status.

[0027] In some embodiments, the status transmission data corresponding to the manual button 5 includes a ventilation shutdown signal. The manual button 5 serves as an emergency control component of the ventilation system. When on-site personnel discover an abnormal situation or need to manually intervene in the system operation, pressing the manual button 5 will send a ventilation shutdown signal to the ventilation control module 1 in real time, thereby enabling the forced shutdown of the exhaust device 3 and the air intake device 4.

[0028] In some embodiments, the control node signals output by the ventilation control module 1 include a power signal, an on signal, an off signal, a fault signal, and a battery signal. When the ventilation control module 1 detects that the exhaust device 3 and the air intake device 4 are on, it outputs a power signal, an on signal, a fault signal, and / or a battery signal. When the ventilation control module 1 detects that the exhaust device 3 and the air intake device 4 are off, it outputs a power signal, an off signal, and / or a fault signal.

[0029] In some embodiments, the conditions for opening the exhaust device 3 and the air intake device 4 are as follows: when the gas detector 2 detects that the concentration of combustible gas in the energy storage compartment has reached the preset alarm threshold, the ventilation control module 1 will immediately output an opening signal to drive the exhaust device 3 and the air intake device 4 to start synchronously, so as to quickly realize the gas replacement between the inside and outside of the compartment and reduce the concentration of combustible gas in the compartment.

[0030] In some embodiments, the exhaust device 3 and the air intake device 4 are shut off under the following conditions: when the gas detector 2 detects that the concentration of combustible gas in the cabin has dropped to a safe range that does not reach the alarm threshold, the ventilation control module 1 automatically outputs a shutdown signal; or, when the manual button 5 is triggered or when the battery management system sends a battery shutdown signal, the ventilation control module 1 is triggered to send a ventilation shutdown signal, and the ventilation control module 1 responds to the manual command by outputting a shutdown signal; and the manual signal and the battery shutdown signal have higher priority than the automatic control signal to ensure the effectiveness of emergency operations.

[0031] Reference Figures 1-5 The present invention also provides an embodiment of an energy storage ventilation device control system, which is executed via the energy storage ventilation device control method as described in the above embodiment. The control system includes a ventilation control module 1, an exhaust device 3, an air intake device 4, a gas detector 2, a manual button 5, and a controller module 6. The ventilation control module 1 is integrated inside the exhaust device 3. The ventilation control module 1 is electrically connected to the exhaust device 3, the air intake device 4, the gas detector 2, the manual button 5 and the controller module 6. It can continuously acquire the operating status transmission data fed back by the gas detector 2, the exhaust device 3, the air intake device 4 and the manual button 5 through a specified communication link based on a preset transmission address, and perform real-time analysis and verification of various data, and output the corresponding control node signals. Furthermore, the exhaust device 3 can receive control node signals output by the ventilation control module 1 in real time and precisely control its own exhaust process according to the signal instructions; when a dangerous situation such as a flammable gas leak occurs in the energy storage compartment, the exhaust device 3 can start quickly and run continuously to promptly discharge the flammable and harmful gases accumulated in the compartment, reducing the risk of explosion and combustion; when the danger is eliminated, it can respond to the shutdown command to stop the exhaust, avoiding ineffective energy consumption; Furthermore, the air intake device 4 also uses the control node signal output by the ventilation control module 1 as the action command to achieve precise control of the air intake process; when an emergency occurs, the air intake device 4 starts simultaneously, continuously drawing in fresh outside air into the energy storage compartment, forming air convection between the inside and outside of the compartment with the exhaust device 3, greatly improving the replacement efficiency of dangerous gases in the compartment; when the emergency ends, the air intake device 4 responds to the shutdown command to stop air intake, ensuring the stability of the environment inside the energy storage compartment; Furthermore, the gas detector 2 can detect the concentration of combustible gas in the cabin in real time and accurately. When the gas concentration is detected to reach or exceed the preset safety alarm threshold, it determines that a hazard has occurred and will immediately send a hazard alarm signal to the ventilation control module 1. When the gas concentration is detected to drop back to the safety threshold range, it determines that the hazard has ended and will promptly send a hazard elimination signal. Furthermore, the manual button 5 has the highest priority control authority. When on-site staff discover an abnormal situation or need to manually intervene in the system operation, pressing the manual button 5 will send a real-time signal to the ventilation control module 1 to shut down the ventilation, forcing the exhaust device 3 and the air intake device 4 to stop operating, thus meeting the operational needs of emergency response. Furthermore, the controller module 6 can receive control node signals output by the ventilation control module 1 in real time, record and store the operating status of the system in real time, and realize command interaction with other subsystems of the energy storage system (such as the battery management system). In the event of an emergency, it can link and control the disconnection of power supply and other related equipment components.

[0032] In some embodiments, the ventilation control module 1 is provided with a power transmission interface, a control node interface, and a communication signal interface: The power input interface includes L_IN, N_IN and E_IN interfaces, and supports two AC220V / 50Hz and AC115V / 60Hz mains power input specifications, which can be adapted to the power grid standards of different regions. The power output interface includes an L_OUT interface and an N_OUT interface, which serve as dedicated power supply interfaces for the fan 31, providing stable power to the fan 31 of the exhaust device 3; The DC power input interface includes a 24V- interface and a 24V+ interface, supporting DC24V DC power input to meet the low power supply requirements of the module itself and peripherals. The DC power supply output interface includes M1, M2 and M3 interfaces, with an output specification of DC24V, specifically designed to power the linear actuator motor; The dry contact signal input interface includes a BMS interface and a GAS interface. The BMS interface is used to receive the linkage signal from the battery management system. When the BMS signal is closed, the ventilation equipment that is already in the open state will immediately shut down. When the BMS signal is open, the equipment can start operation in response to the explosion-proof control signal (i.e., gas alarm signal) input from the GAS interface. The GAS interface is used to receive the alarm signal from gas detector 2. When the GAS signal is closed, it triggers the ventilation equipment to open. When the GAS signal is open, it controls the ventilation equipment to close. The dry contact signal output interface includes a Power interface, a Fault interface, a Status interface, an RE1 interface, and a RE2 interface. The Power interface signal remains closed when the control module is powered on and open when powered off, providing direct feedback on the module's power supply status. The Fault interface signal is open when devices such as the exhaust device 3 and the intake device 4 are normally open or closed. It closes when any ventilation device experiences a short circuit, open circuit, or other fault and cannot operate normally, providing real-time warning of fault conditions. The Status interface signal remains closed when all ventilation devices are on and opens when all devices are off, providing real-time feedback on the device's operating status. The RE1 and RE2 interfaces are reserved output interfaces, allowing users to customize functions according to their actual needs, improving the system's scalability. The communication signal interface is an RS485 interface, which can establish a stable communication connection with the host computer. It allows maintenance personnel to remotely query key information such as the on / off status and fault type of the ventilation equipment through the host computer. It also supports remote control of the ventilation equipment to turn it on and off via commands, thereby realizing remote monitoring and maintenance.

[0033] In some embodiments, the performance parameters of the ventilation control module 1 are: The operating and storage environment temperature range is -40℃ to 70℃, which can adapt to harsh climatic environments such as high cold and high temperature, and meet the application needs of different regions. The circuit board has a rated operating voltage of DC24V, a standby power as low as 0.4W, and a rated operating current of 0.03A±20%, combining the advantages of low power consumption and stability. The supported fan 31 voltage specifications are AC220V / 50Hz and AC115V / 60Hz, and the corresponding maximum output power of the fan 31 is 300W. The supported actuator motor voltage specification is DC24V, and the corresponding maximum output power of the actuator is 50W, which can be adapted to peripherals with different power specifications. The circuit board has a flame retardant rating of UL94V-0 and is UL certified, possessing excellent fire safety performance. In some embodiments, the ventilation control module 1 integrates power reverse connection protection and current overload protection functions. When the positive and negative terminals of the power supply are reversed, the protection mechanism can be activated immediately to prevent the circuit board from being burned due to reverse connection. When the operating current of the equipment exceeds the set maximum threshold, the power supply circuit can be automatically cut off to prevent the equipment from being damaged due to overload and effectively extend the service life of the equipment.

[0034] In some embodiments, the ventilation device 3 includes a fan 31 and a first push rod 32. The first push rod 32 is connected to the first louver 33, and the first louver 33 can be opened and closed by the extension and retraction of the push rod, so as to achieve efficient ventilation or sealing protection in conjunction with the fan 31. Correspondingly, the air intake device 4 includes a second push rod 41, which is connected to the second louver 43. The extension and retraction of the push rod drives the opening and closing of the second louver 43 to achieve efficient air intake.

[0035] In some embodiments, a power module 7 is also included. The power module 7 is integrated inside the exhaust device 3 and is electrically connected to the ventilation control module 1, providing a stable and continuous power supply to the ventilation control module 1 and its peripheral components.

[0036] Working principle: Based on the pre-configured transmission address data of each device, the ventilation control module 1 continuously acquires the operating status transmission data fed back by the gas detector 2, exhaust device 3, air intake device 4 and manual button 5 through a designated communication link, and performs real-time analysis and logical judgment. When the gas detector 2 detects that the concentration of combustible gas in the energy storage compartment has reached the alarm threshold, determines that a dangerous situation has occurred and sends a dangerous situation alarm signal, the ventilation control module 1 will immediately output the corresponding control node signal, instruct the exhaust device 3 and the air intake device 4 to open synchronously, start the emergency ventilation and exhaust program, and quickly replace the dangerous gas in the compartment. When the gas detector 2 detects that the concentration of combustible gas has dropped to the safety threshold and sends a hazard elimination signal, or when the on-site staff presses the manual button 5 to send a ventilation shutdown signal, the ventilation control module 1 will output a shutdown command to control the exhaust device 3 and the air intake device 4 to stop operating and terminate the ventilation procedure.

[0037] Through the above technical solution, the ventilation control module 1 of this application adopts a miniaturized integrated design, with a compact size. It does not require an external control cabinet and can be directly installed inside the conventional energy storage exhaust device 3, effectively saving installation space and reducing wiring complexity and equipment investment costs. It can achieve seamless linkage with the fire extinguishing system and battery management system (BMS). When an emergency occurs, each system can coordinate to activate the protection program, effectively improving the overall safety protection level of the energy storage system. It is equipped with an RS485 high-speed communication interface, supporting real-time communication with the host computer. It also supports remotely turning the ventilation equipment on or off via commands. Maintenance personnel can view the operating status and fault information of the ventilation device online, realizing timely early warning and rapid handling of faults, effectively reducing the risk of equipment loss of control, and comprehensively improving the operational reliability of the energy storage fire protection system.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
