[0002] Energy storage cabinets, as devices capable of storing electrical energy, are widely used in industrial and commercial sectors to store energy when power supply is sufficient and release it during peak demand periods or when power is insufficient. However, when the energy storage batteries in an energy storage cabinet experience thermal runaway, timely fire suppression is often impossible, leading to major fires. Although existing energy storage cabinets are equipped with fire suppression systems, these systems are ineffective at extinguishing fires and cannot effectively contain their spread or extinguish them promptly.

[0003] The main objective of this application is to provide an energy storage cabinet to solve the problem that the fire extinguishing effect of the fire protection system of the energy storage cabinet in the prior art is poor.

[0007] When the fire monitoring component detects that the smoke concentration inside the cabinet is not less than a first threshold, it activates the exhaust component to discharge the airflow inside the cabinet to the outside of the cabinet. When the smoke concentration inside the cabinet is not less than the first threshold and the temperature inside the cabinet is not less than a second threshold, it activates the fire extinguishing device and shuts down the exhaust component.
[0008] Furthermore, the fire extinguishing device includes a signal input terminal and a first feedback terminal, and the fire monitoring component includes:
[0009] The monitoring device is electrically connected to the exhaust assembly and the first feedback terminal;
[0010] An environmental monitoring component, which is installed inside the cabinet and electrically connected to the monitoring device and the signal input terminal, wherein the environmental monitoring component will input a start signal to the signal input terminal when it detects that the smoke concentration is not less than the first threshold and the temperature is not less than the second threshold; and / or;

[0014] Furthermore, the cabinet is provided with a battery compartment, and the battery pack is installed in the battery compartment. Along the height direction of the cabinet, the environmental monitoring component is installed in the battery compartment and located on the top wall of the battery compartment.
[0015] Furthermore, the cabinet is provided with a battery compartment and a vent, the battery pack is installed in the battery compartment, and the vent is provided through the side wall of the battery compartment. The exhaust assembly includes:
[0016] An exhaust fan is installed at the vent.
[0017] An exhaust valve is electrically connected between the exhaust fan and the monitoring device.
[0018] Furthermore, the cabinet is provided with a battery compartment, and the battery packs include multiple battery packs, which are stacked and installed in the battery compartment along the height direction of the cabinet. The fire protection system also includes:

[0020] Furthermore, along the height direction of the cabinet, the fire extinguishing device is installed inside the battery compartment and located on the top wall of the battery compartment; and / or,
[0021] The extinguishing agent spraying component includes:
[0022] The spraying element includes multiple spraying elements, which are disposed one-to-one on multiple battery packs. Each spraying element includes a nozzle, which communicates with the receiving cavity.
[0023] The fire extinguishing device is connected to the nozzles of the plurality of spray elements via the connecting pipe.
[0024] Furthermore, the fire protection system also includes:

[0033] In this application, the fire protection system of the energy storage cabinet includes a fire monitoring component, an exhaust component, and a fire extinguishing device. When the fire monitoring component detects that the smoke concentration inside the energy storage cabinet is not less than a first threshold, it activates the exhaust component, thereby discharging the airflow inside the cabinet to the outside. Smoke and toxic gases are then discharged with the airflow, effectively curbing the spread and development of the fire in its early stages. Furthermore, the fire monitoring component can also activate the fire extinguishing device and shut down the exhaust component when the smoke concentration inside the cabinet is not less than the first threshold and the temperature inside the cabinet is not less than a second threshold. Simultaneously, the exhaust component is closed when the fire extinguishing device is activated; therefore, no high-velocity airflow is generated inside the cabinet, preventing the fire from spreading due to airflow after ignition, and facilitating the timely and rapid extinguishing of the fire by the fire extinguishing device, thus improving the fire extinguishing effect.

[0043] Existing fire suppression systems for energy storage cabinets (such as lithium battery energy storage cabinets) rely heavily on single sensors (such as smoke or heat detectors) to trigger fire suppression. Such systems are less effective at extinguishing fires and are prone to delayed response and false activation. Furthermore, they lack the ability to handle toxic gases (such as hydrogen), making it difficult to accurately distinguish the stages of a fire and potentially leading to wasted extinguishing agents or secondary injuries.
[0044] To address the aforementioned issues, this application provides an energy storage cabinet, please refer to [link / reference]. Figures 1 to 3 The energy storage cabinet includes a main body 10 and a fire protection system 20. The main body 10 includes a cabinet 11 and a battery pack 12, which is installed inside the cabinet 11. The battery pack 12 includes a housing and battery cell modules. The housing has a receiving cavity, and the battery cell modules are disposed within the receiving cavity. The battery cell module may include one or more battery cells, which is not the only limitation of this application.
[0045] The fire protection system 20 includes a fire monitoring component 21, an exhaust component 22, and a fire extinguishing device 23. The fire monitoring component 21 is installed in the cabinet 11. The exhaust component 22 is installed in the cabinet 11 and electrically connected to the fire monitoring component 21, enabling the fire monitoring component 21 to activate or deactivate the exhaust component 22. The fire extinguishing device 23 is installed inside the cabinet 11 and electrically connected to the fire monitoring component 21, enabling the fire monitoring component 21 to activate or deactivate the fire extinguishing device 23.
[0046] Specifically, when the fire monitoring component 21 detects that the smoke concentration inside the cabinet 11 is not less than a first threshold, it activates the exhaust component 22 to discharge the airflow inside the cabinet 11 to the outside, thereby timely removing smoke and toxic gases from the cabinet 11 in the early stages of a fire. For example, the first threshold may include 0.15 dB / m (dB / m is a unit used to measure smoke concentration), meaning that when the smoke concentration is not less than 0.15 dB / m, the exhaust component 22 can be activated, thus achieving accurate judgment of the early stage of a fire and effectively curbing its spread. Furthermore, the fire monitoring component 21 can activate the fire extinguishing device 23 and shut down the exhaust component 22 when the smoke concentration inside the cabinet 11 is not less than the first threshold and the temperature inside the cabinet 11 is not less than a second threshold. In other words, it can simultaneously trigger the fire extinguishing device 23 to extinguish the fire based on both the smoke concentration and temperature indicators, achieving accurate judgment of the fire stage and extinguishing the fire. Meanwhile, since the exhaust assembly 22 is closed during the operation of the fire extinguishing device 23, and the fire extinguishing device 23 is connected to the accommodating cavity of the battery pack 12, it can prevent the fire from spreading under the influence of airflow, while ensuring that the extinguishing agent can quickly reach the extinguishing concentration and directly act on the battery cell module, thereby achieving efficient fire extinguishing. Therefore, after the fire extinguishing device 23 is activated, it can avoid the waste of extinguishing agent, allowing the sprayed extinguishing agent to directly act on the fire location, and can avoid affecting other devices that have not yet caught fire, resulting in a better fire extinguishing effect.
[0047] In some embodiments of this application, such as when the first threshold includes 0.15 dB / m and the second threshold includes 80°C, the fire extinguishing device 23 can be activated and the exhaust assembly 22 can be shut off when the smoke concentration is not less than 0.15 dB / m and the temperature is not less than 80°C.
[0048] As can be seen, in this application, the fire protection system 20 of the energy storage cabinet includes a fire monitoring component 21, an exhaust component 22, and a fire extinguishing device 23. When the fire monitoring component 21 detects that the smoke concentration inside the cabinet 11 of the energy storage cabinet is not less than a first threshold, it activates the exhaust component 22, thereby discharging the airflow inside the cabinet 11 to the outside of the cabinet 11. Smoke and toxic gases can then be discharged outside the cabinet 11 with the airflow, effectively curbing the spread and development of the fire in its early stages. Furthermore, the fire monitoring component 21 can also activate the fire extinguishing device 23 and close the exhaust component 22 when the smoke concentration inside the cabinet 11 is not less than the first threshold and the temperature inside the cabinet 11 is not less than a second threshold. Simultaneously, the exhaust component 22 is closed while the fire extinguishing device 23 is activated. Therefore, no high-velocity airflow is generated inside the cabinet 11, thus preventing the fire from spreading under the influence of airflow after ignition, and making it easier for the fire extinguishing device 23 to extinguish the fire quickly and effectively, improving the fire extinguishing effect.
[0049] When the fire extinguishing device 23 is connected to the accommodating cavity, it can directly apply the extinguishing agent to the battery cell modules within the accommodating cavity. This directly controls the thermal runaway of the energy storage cabinet within the battery pack 12, allowing the extinguishing agent to quickly reach the extinguishing concentration, thus suppressing the combustion reaction more rapidly. This reduces waste and ineffective utilization of the extinguishing agent, avoids unnecessary impact on non-faulty components and / or other battery packs 12 within the energy storage cabinet, and improves the fire extinguishing effect while reducing economic losses.
[0050] The fire extinguishing device 23 includes a signal input terminal and a first feedback terminal 233. The fire monitoring component 21 provided in this application includes a monitoring device 211 and an environmental monitoring component 212. The monitoring device 211 is electrically connected to the exhaust assembly 22 and the first feedback terminal 233 of the fire extinguishing device 23, so that the monitoring device 211 can determine whether to activate or deactivate the exhaust assembly 22 based on the feedback signal transmitted from the first feedback terminal 233. The monitoring device 211, i.e., an industrial control computer or monitoring system, integrates control, data acquisition / management, and monitoring functions, and can cooperate with the fire protection system 20 to perform emergency energy control and ensure fire safety in the event of a fire or other economic emergency.
[0051] The environmental monitoring component 212 is installed inside the cabinet 11 and is electrically connected to the signal input terminals of the monitoring device 211 and the fire extinguishing device 23. When the environmental monitoring component 212 detects that the smoke concentration is not less than the first threshold and the temperature is not less than the second threshold, it will input an activation signal to the signal input terminal so that the fire extinguishing device 23 can activate in response to the activation signal and simultaneously send the activated feedback signal back to the monitoring device 211 via the first feedback terminal 233. The monitoring device 211 can then respond to the received feedback signal and close the opened exhaust assembly 22.
[0052] As can be seen, this application can directly activate the fire extinguishing device 23 by inputting a start signal to the signal input terminal of the fire extinguishing device 23 when the detected smoke concentration and temperature reach the trigger conditions (i.e., the first threshold and the second threshold), thus enabling more timely and precise control of the fire extinguishing operation. Furthermore, after the fire extinguishing device 23 feeds back its activation feedback signal to the monitoring device 211, the monitoring device 211 can promptly shut off the exhaust assembly 22, ensuring precise and timely control and reducing the control design complexity of the fire monitoring component 21. Simultaneously, the first and second thresholds detected by the environmental monitoring component 212 can also be transmitted to the monitoring device 211 for real-time monitoring.
[0053] In some embodiments, the environmental monitoring component 212 may include a first sensor for detecting temperature and a second sensor for detecting smoke concentration, both of which are electrically connected to the monitoring device 211. The monitoring device 211 can determine whether to activate the fire extinguishing device 23 and the exhaust assembly 22 based on the data detected by the first and second sensors. When the environmental monitoring component 212 includes the first and second sensors, it may also include a controller. In this case, the first and second sensors can be electrically connected to the controller, and the controller can be electrically connected to the fire extinguishing device 23. Once the data monitored by the first and second sensors reach the corresponding thresholds, the controller can activate the fire extinguishing device 23.
[0054] like Figure 2 and Figure 3As shown, the environmental monitoring component 212 in this application includes a smoke and heat detector 120, which includes a communication terminal 201 and a signal output terminal. The communication terminal 201 is communicatively connected to the monitoring device 211, enabling the monitoring device 211 to receive smoke concentration data and temperature data detected by the smoke and heat detector 120 in real time. The signal output terminal is electrically connected to the signal input terminal of the fire extinguishing device 23, so that when the detected smoke concentration data reaches a first threshold and the temperature data reaches a second threshold, the smoke and heat detector 120 sends an activation signal to the fire extinguishing device 23, achieving data transmission and activation of the fire extinguishing device 23 without the need for complex control logic. Furthermore, the smoke and heat detector 120 is easy to install and does not occupy much installation space in the cabinet 11.
[0055] like Figure 3 As shown, in some embodiments, the signal input terminals of the fire extinguishing device 23 include a positive input terminal 231 and a negative input terminal 232. The signal output terminals of the smoke and heat detector 120 include a positive output terminal 202 and a negative output terminal 203. When electrically connecting the smoke and heat detector 120 and the fire extinguishing device 23, the positive output terminal 202 and the positive input terminal 231 are connected, and the negative output terminal 203 and the negative input terminal 232 are connected. The smoke and heat detector 120 is electrically connected to the positive and negative terminals of the power supply device via its own power supply positive and negative terminals, enabling the power supply device to output 24V voltage to the smoke and heat detector 120. The fire extinguishing device 23 also includes a second feedback terminal 234, which is connected to the positive terminal of the power supply device, ensuring that the fire extinguishing device 23, the power supply device, and the smoke and heat detector 120 form a complete circuit, ensuring the normal operation of the fire extinguishing process.
[0056] The smoke and heat detector 120 can communicate with the monitoring device 211 via a communication terminal 201 based on a CAN bus (Controller Area Network, a serial communication protocol bus for real-time applications). The monitoring device 211 connects to the positive and negative terminals of the power supply through its own wiring terminals to ensure that the monitoring device 211 can work normally.
[0057] The energy storage cabinet 11 is equipped with a battery compartment 101, and the battery pack 12 is installed inside the battery compartment 101. Along the height of the cabinet 11, the environmental monitoring component 212 is installed inside the battery compartment 101 and located on the top wall of the battery compartment 101. This not only improves the accuracy of the environmental monitoring component 212 in monitoring smoke concentration, but also improves the space utilization of the battery compartment 101 without occupying the installation space of the battery pack 12.
[0058] In this application, the cabinet 11 is also provided with a control compartment 102, which is located below the battery compartment 101 along the height direction of the cabinet 11. The control compartment 102 can house the control box 30 of the energy storage cabinet, water immersion sensors, circuit breakers, liquid cooling units, and other devices.
[0059] The cabinet 11 is equipped with a battery compartment 101 and a vent 103, and the battery pack 12 is installed inside the battery compartment 101. The vent 103 extends through the side wall of the battery compartment 101. The exhaust assembly 22 includes an exhaust fan 221 and an exhaust valve 222. The exhaust fan 221 is installed at the vent 103 so that when the exhaust fan 221 is activated, smoke, toxic gases, etc., can be discharged to the outside of the cabinet 11 through the vent 103. The exhaust valve 222 is electrically connected between the exhaust fan 221 and the monitoring device 211 so that the monitoring device 211 can control the opening and closing of the exhaust valve 222 to start or stop the exhaust fan 221 after receiving a feedback signal from the fire extinguishing device 23.
[0060] like Figure 1 As shown, the cabinet 11 may include a first door panel 111, a second door panel 112, and a main frame 113. Along the height direction of the cabinet 11, the main frame 113 forms a first mounting groove and a second mounting groove. The first door panel 111 is connected to the main frame 113 and is positioned opposite to the first mounting groove. The first door panel 111 has a first position where it rotates to cover the first mounting groove to form a battery compartment 101, and a second position where the first mounting groove is open. The second door panel 112 is connected to the main frame 113 and is positioned opposite to the second mounting groove. The second door panel 112 has a third position where it rotates to cover the second mounting groove to form a control compartment 102, and a fourth position where the second mounting groove is open. Along the height direction of the cabinet 11, a vent 103 may be located on the upper side of the first door panel 111 away from the control compartment 102, and a monitoring device 211 may also be located on the first door panel 111 and below the vent 103. Therefore, while making full use of the installation space of the first door panel 111, it is convenient to open the first door panel 111 to install and maintain the exhaust assembly 22 and the monitoring device 211.
[0061] When the cabinet 11 is equipped with a battery compartment 101, multiple battery packs 12 are included, and these battery packs 12 are stacked and installed within the battery compartment 101 along the height direction of the cabinet 11. The fire protection system 20 also includes a fire extinguishing agent spraying component 24, which connects the fire extinguishing device 23 and the housing cavities of the multiple battery packs 12. The fire extinguishing agent spraying component 24 can simultaneously and efficiently spray the fire extinguishing agent of the fire extinguishing device 23 into the housing cavities of the multiple battery packs 12, thereby achieving rapid extinguishing of the fire.
[0062] The fire extinguishing device 23 in this embodiment may include either a perfluoroethyl ketone (PFK) fire extinguishing device 23 or an aerosol fire extinguishing device 23. The PFM fire extinguishing device 23 sprays PFM as the extinguishing agent. The PFM fire extinguishing device 23 has high extinguishing efficiency and fast extinguishing speed, quickly suppressing flames and high temperatures in the battery pack 12. It is highly targeted at fires caused by battery cell modules and leaves no residue after extinguishing, resulting in good cleanliness. The aerosol fire extinguishing device 23 sprays aerosol as the extinguishing agent. This type of fire extinguishing device 23 has lower cost and is suitable for installation in compact energy storage cabinets. After the aerosol is released, it can quickly fill the containment cavity of the battery pack 12, effectively suppressing the spread of fire.
[0063] Along the height of the cabinet 11, the fire extinguishing device 23 is installed inside the battery compartment 101 and located on the top wall of the battery compartment 101, so as to make full use of the installation space between the battery pack 12 located at the highest position in the battery compartment 101 and the top wall, thereby improving the space utilization rate of the battery compartment 101. When the environmental monitoring component 212 is also located on the top wall of the battery compartment 101, the environmental monitoring component 212 and the fire extinguishing device 23 can be arranged alternately or adjacently, which is convenient for assembly.
[0064] The fire extinguishing agent spraying component 24 includes spraying elements 241 and connecting pipes 242. Multiple spraying elements 241 are correspondingly mounted on multiple battery packs 12. Each spraying element 241 includes a nozzle that communicates with a receiving cavity, allowing the fire extinguishing agent to be sprayed into the receiving cavity for rapid fire extinguishing. The fire extinguishing device 23 is connected to the nozzles of the multiple spraying elements 241 via the connecting pipes 242. Thus, the fire extinguishing device 23 can transmit the fire extinguishing agent through the connecting pipes 242 to the nozzles of each spraying element 241, enabling each spraying element 241 to spray the fire extinguishing agent into the battery pack 12, facilitating assembly. Specifically, the connecting pipes 242 can be vertically installed along the height of the cabinet 11 to improve the neatness of the fire extinguishing agent spraying component 24, save on the length of the connecting pipes 242, and avoid occupying too much space in the battery compartment 101.
[0065] The fire protection system 20 also includes an activation button 25, which is installed on the cabinet 11 and electrically connected to the fire extinguishing device 23. This allows the user to activate the fire extinguishing device 23 by pressing the activation button 25 as needed. The activation button 25 can also be installed on the first door panel 111 of the cabinet 11 for easy user operation.
[0066] The fire protection system 20 also includes an alarm 26, which is installed in the cabinet 11 and electrically connected to the monitoring device 211. The monitoring device 211 can control the alarm 26 to sound an alarm when the smoke concentration detected by the environmental monitoring component 212 reaches a first threshold and the temperature reaches a second threshold. The alarm 26 may include an audible and visual alarm to enhance the alert intensity. The alarm 26 may be installed on the top of the cabinet 11.
[0067] like Figure 2 As shown, the energy storage cabinet in this application also includes a control box 30, a grid connection switch 40, and a temperature sensor 50. The control box 30 is installed inside the cabinet 11 and electrically connected to the battery pack 12. The grid connection switch 40 is electrically connected to the control box 30 and the fire monitoring component 21. The grid connection switch 40 is used to connect the energy storage cabinet to the external power grid to realize the transmission and storage of electrical energy. Specifically, the grid connection switch 40 is electrically connected to the monitoring device 211 of the fire monitoring component 21 so that the monitoring device 211 can control the opening or closing of the grid connection switch 40.
[0068] Temperature sensor 50 is disposed within the housing cavity of battery pack 12 and electrically connected to fire monitoring component 21. Temperature sensor 50 can detect the temperature of the battery cell module. Furthermore, when fire monitoring component 21 detects that the smoke concentration is not less than a first threshold and the temperature detected by temperature sensor 50 (i.e., the temperature of the battery cell module) is greater than a third threshold, it controls grid connection switch 40 to shut down, thereby preventing damage from the fire from affecting the external power grid.
[0069] As can be seen, the energy storage cabinet provided in this application can monitor the fire situation in real time through its fire protection system 20 and control the exhaust assembly 22 and fire extinguishing device 23 to take corresponding actions in a timely manner. The fire protection system 20 effectively curbs the spread of the fire in the early stage, and extinguishes the fire in a timely manner through the fire extinguishing device 23 during the fire stage, reducing fire losses, improving fire extinguishing effect, and providing higher fire safety reliability. It is suitable for various types of industrial and commercial places, such as data centers, communication base stations, and industrial plants.
[0070] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0071] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
[0072] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
