Description

Technical Field

[0001] This disclosure relates to the field of energy storage technology, and in particular to an energy storage system with intelligent fire-fighting function based on supramolecular halogenated hydrocarbon fire extinguishing media. Background Technology

[0002] Energy storage containers mainly consist of two parts: an equipment compartment and a battery compartment. Each part contains various components, such as a containerized equipment room, battery packs, a battery management system, energy storage converters, and a thermal management system. The equipment compartment primarily houses the power distribution cabinets and inverters for better circuit control, while the battery compartment mainly stores the battery packs. Whether on the user side, the power supply side, or the grid side, safety is always the primary requirement for energy storage. Currently, most fire suppression solutions for energy storage containers rely on gaseous fire suppression systems. However, this method suffers from low extinguishing efficiency due to the gaseous extinguishing medium, a high risk of reignition, and the need for extensive spraying of the entire container, resulting in large quantities of equipment required.

[0010] In an embodiment of the first aspect, the control unit is further configured to determine the fire situation based on the environmental information monitored by the monitoring unit in order to select whether to continue or stop the fire suppression action, including: in response to a continuously abnormal battery pack not being located at the top of its group of battery packs, when performing the fire suppression action, obtaining the abnormal distribution of the group of battery packs based on the real-time environmental information, and determining whether the fire is spreading upwards; if it is spreading, continuing the fire suppression action until all abnormal battery packs are suppressed.

[0011] In an embodiment of the first aspect, the control unit is further configured to obtain the upward spread rate of the fire based on the real-time environmental information, and control the first control component to adjust the injection flow rate of the coolant based on the spread rate, so that the filling rate in the battery compartment is higher than the spread rate.

[0012] In an embodiment of the first aspect, the control unit is further configured to control the first control component to maintain the spraying fire extinguishing action of the spray nozzle on the abnormal battery pack that has not been submerged when the fire extinguishing action is executed; wherein the first control component and the second control component are controlled to coordinate the flow rates between the first tube and the second tube to achieve a submersion rate higher than the spread rate.

[0013] In an embodiment of the first aspect, the control unit is further configured to control the first control component to maintain the spraying fire extinguishing action of the spray nozzle on the abnormal battery pack that has not been submerged when the fire extinguishing action is executed.

[0014] In an embodiment of the first aspect, the monitoring unit includes a plurality of smoke and temperature composite sensors disposed in the battery compartment and corresponding to each of the battery packs; the primary fire alarm signal is an alarm signal issued by one of the plurality of composite sensors.

[0015] In an embodiment of the first aspect, the secondary fire alarm signal is that the smoke and temperature composite sensor that issued the alarm signal continues to issue an alarm signal after a specified condition is met.

[0016] In an embodiment of the first aspect, the battery pack whose specified condition is abnormal is cooled by coolant sprayed from the nozzle within a specified time.

In response to receiving a Level 1 fire alarm signal indicating a battery pack malfunction from the environmental information, the control unit at least activates the spray nozzle corresponding to the malfunctioning battery pack to perform a spray extinguishing action on the malfunctioning battery pack. If the spray extinguishing action on the malfunctioning battery pack has already been performed, the control unit, in response to receiving a Level 2 fire alarm signal indicating a persistent malfunction from the environmental information, activates the filling port to perform a flooding extinguishing action, filling the battery compartment with coolant until it submerges the persistently malfunctioning battery pack. This disclosure, through the first and second pipes, enables the battery pack to be sequentially sprayed for Level 1 fire alarm signals and flooded for Level 2 fire alarm signals for extinguishing and cooling. This not only improves firefighting efficiency and ensures the safety of the battery compartment but also reduces coolant consumption and firefighting costs through tiered extinguishing and cooling of the battery pack.

[0039] Energy storage containers mainly consist of two parts: an equipment compartment and a battery compartment. Each part contains various components, such as a containerized equipment room, battery packs, a battery management system, energy storage converters, and a thermal management system. The equipment compartment primarily houses the power distribution cabinets and inverters for better circuit control, while the battery compartment mainly stores the battery packs. Whether on the user side, the power supply side, or the grid side, safety is always the primary requirement for energy storage. Currently, most fire suppression solutions for energy storage containers rely on gaseous fire suppression systems. However, this method suffers from low extinguishing efficiency due to the gaseous extinguishing medium, a high risk of reignition, and the need for extensive spraying of the entire container, resulting in large quantities of equipment required.

[0040] Based on the above problems, this disclosure, through the first and second pipes, can sequentially perform spray fire extinguishing and cooling corresponding to the first-level fire alarm signal and flood fire extinguishing and cooling corresponding to the second-level fire alarm signal on the battery pack. This not only ensures the safety of the battery compartment, but also reduces the amount of coolant used and lowers fire protection costs by tiered fire extinguishing and cooling of the battery pack.

[0041] Figure 1 The diagram shown is an overall structural schematic of an energy storage system with intelligent fire-fighting function based on supramolecular halogenated hydrocarbon fire extinguishing media, according to an embodiment of this disclosure. Figure 2 The diagram shown is a cross-sectional view of the battery compartment in one embodiment of this disclosure. Figure 3 The diagram shown is a schematic representation of the circuit connection structure in one embodiment of this disclosure. Figure 1 , Figure 2 and Figure 3In the example, the energy storage system 100 with intelligent fire-fighting function based on supramolecular halogenated hydrocarbon fire extinguishing medium includes a housing 110, at least one battery pack 120, fire-fighting components 130, a monitoring unit 140, and a control unit 150.

[0042] For example, the housing 110 includes a battery compartment 111 and an equipment compartment 112 formed by separation. In this embodiment, for instance, the battery compartment 111 and the equipment compartment 112 are formed by a left-right, sealed separation within the space of the housing 110, facilitating the assembly of the energy storage system 100 with intelligent fire-fighting functionality based on supramolecular halogenated hydrocarbon extinguishing media by construction personnel. It should be noted that the holes between the equipment compartment 112 and the battery compartment 111 for wire harness passage need to be sealed. In other embodiments, the battery compartment 111 and the equipment compartment 112 can also be implemented as vertically separated by a vertical separation within the space of the housing 110 (with the equipment compartment 112 above the battery compartment 111). This way, even if subsequent injection of extinguishing agents or other liquids into the battery compartment 111 will not affect the equipment compartment 112 above it.

[0043] For example, at least one group of the battery packs 120 are spaced apart in the battery compartment 111 along the vertical direction. The number of columns in which the at least one group of battery packs 120 are distributed vertically varies with the number of battery packs 120, and can be one column or multiple columns. This embodiment is described using two columns.

[0044] It should be noted that the battery pack 120 can be implemented as a lead-acid battery, a lithium-ion battery (such as a lithium iron phosphate battery, a ternary lithium battery, etc.), a flow battery, and a sodium-ion battery, and can be a brand new battery pack 120 or a used battery pack 120 after disassembly.

[0045] Exemplarily, the fire suppression assembly 130 includes at least one first pipe 131 and a second pipe 132 communicating with an external device storing coolant. Figure 2 In the example, the first tube 131 is implemented as a single unit, with one end connected to an external device and the other end forming a filling port 13101 connecting to the battery compartment 111. A first control component 1311 is provided within the filling port 13101. Exemplarily, the first control component 1311 may be at least one of a solenoid valve and a mass flow controller.

[0046] In some embodiments, the coolant is implemented as a supramolecular halogenated hydrocarbon fire extinguishing agent. The core component of the supramolecular halogenated hydrocarbon fire extinguishing agent is a hydrocarbon containing fluorine, chlorine, and bromine, such as heptafluoropropane (C3HF7) or hexafluoropropane (C3H2F6). The bromide ions in its molecules can interrupt the hydroxyl radicals generated during combustion when heated, thereby quickly extinguishing the flame. The supramolecular halogenated hydrocarbon fire extinguishing agent has high specific heat characteristics, enabling it to quickly absorb the heat released by the battery cell at high temperatures, reducing the surface temperature of the battery cell. The flame retardant in the fire extinguishing agent rapidly captures free radicals in the combustion reaction, blocking the combustion chain and slowing down or even terminating the combustion reaction. The fire extinguishing agent can form a covering layer on the surface of the battery cell, isolating oxygen and absorbing combustible gases. It can quickly become compatible with flammable electrolytes, reducing the concentration of combustibles and preventing the spread of combustion.

[0047] Exemplarily, the second pipe body 132 includes a main pipe 1321 and a plurality of branch pipes 1322. The main pipe 1321 is configured to connect to an external device. One end of each branch pipe 1322 is connected to the main pipe 1321, and the other end forms a plurality of spray nozzles 13201 corresponding to each of the battery packs 120. The plurality of spray nozzles 13201 are positioned above their respective battery packs 120 to spray coolant onto the surface of the battery packs 120 when the circuit is open. Exemplarily, the spray nozzles 13201 are implemented as shower heads to increase the spray area of ​​the coolant. Exemplarily, each branch pipe 1322 is provided with a second control component 1323. Exemplarily, the second control component 1323 may be at least one of a solenoid valve and a mass flow controller.

[0048] For example, the external device is implemented as a water tank, and the volume of the water tank is not less than the volume of the battery compartment 111. In this way, it can be avoided that the coolant in the water tank cannot completely submerge the multiple battery packs 120 after being fully injected into the battery compartment 111.

[0049] For example, the monitoring unit 140 is located in the battery compartment 111 and is used to detect environmental information. The control unit 150 is electrically connected to the first control component 1311 on the first tube 131, a plurality of second control components 1323 on the second tube 132, and the monitoring unit 140. Specifically, in response to obtaining a Level 1 fire alarm signal indicating an abnormality in the battery pack 120 from the environmental information, the control unit 150 at least activates the spray nozzle 13201 corresponding to the abnormal battery pack 120 to perform a spray fire extinguishing action on the abnormal battery pack 120; if the spray fire extinguishing action on the abnormal battery pack 120 has already been performed, in response to obtaining a Level 2 fire alarm signal indicating a continued abnormality in the battery pack 120 from the environmental information, the control unit 150 activates the filling port 13101 to perform a filling fire extinguishing action, filling the battery compartment 111 with coolant until the continuously abnormal battery pack 120 is submerged.

[0050] It is understood that the control unit 150 can respectively connect the filling port 13101 and the spray port 13201 by controlling the opening of the first control component 1311 and the second control component 1323. Correspondingly, the first tube 131 and the second tube 132 are respectively provided with a first infusion pump (not shown in the figure) and a second infusion pump (not shown in the figure) electrically connected to the control unit 150, so as to draw the coolant in the external device into the battery compartment 111 and spray the coolant onto the abnormal battery pack 120 under the control of the control unit 150.

[0051] In this embodiment, the monitoring unit 140 is implemented as a fire detection system. Exemplarily, the monitoring unit 140 includes a plurality of smoke and temperature composite sensors 141 disposed in the battery compartment 111 and corresponding to each of the battery packs 120. The smoke and temperature composite sensors 141 are disposed close to their respective corresponding battery packs 120, for example, above their respective battery packs 120 (due to the upward tendency of smoke and heat).

[0052] For example, the first-level fire alarm signal is an alarm signal issued by one of the multiple smoke and temperature composite sensors 141. The alarm signal may be issued by the smoke and temperature composite sensor 141 when it detects an abnormality in at least one of the smoke or temperature, such as the corresponding abnormal situation of smoke or temperature rise in the battery pack 120.

[0053] For example, the secondary fire alarm signal is that the smoke and temperature composite sensor 141, which issued the alarm signal, continues to issue an alarm signal after a specified condition is met. In this embodiment, the specified condition is that the abnormal battery pack 120 is cooled by the coolant sprayed from the spray nozzle 13201 within a specified time. That is to say, the abnormal battery pack 120 still shows abnormality after being subjected to fire-fighting measures corresponding to the primary fire alarm signal for a certain period of time.

[0054] Those skilled in the art will understand that when one of the battery packs 120 malfunctions, the corresponding smoke and temperature composite sensor 141 issues a Level 1 fire alarm signal. Based on this Level 1 fire alarm signal, the control unit 150 controls the second control component 1323 of the branch pipe 1322 corresponding to the malfunctioning battery pack 120 to open, thereby allowing coolant to be sprayed onto the malfunctioning battery pack 120 through the spray nozzle 13201 for fire extinguishing and cooling. After the coolant has been sprayed for a certain period of time, the smoke and temperature composite sensor 141 corresponding to the malfunctioning battery pack 120 continues to issue an alarm signal. At this time, the control unit 150 determines that the alarm signal is a Level 2 fire alarm signal and activates the first control component 1311 inside the first pipe 131, thereby allowing coolant to be poured into the battery compartment 111 through the filling port 13101 and submerge the malfunctioning battery pack 120.

[0055] This disclosure, through the first pipe body 131 and the second pipe body 132, enables the battery pack 120 to be sequentially sprayed for fire extinguishing and cooling corresponding to a first-level fire alarm signal and flooded for fire extinguishing and cooling corresponding to a second-level fire alarm signal. The spray nozzle 13201 corresponding to the first-level fire alarm signal sprays coolant in a targeted manner, which can improve fire-fighting efficiency, ensure the safety of the battery compartment 111, and also reduce the amount of coolant used and fire-fighting costs by extinguishing and cooling the battery pack 120 in stages.

[0056] exist Figure 2 In this example, the monitoring unit 140 further includes a plurality of liquid level sensors 142 electrically connected to the control unit 150. The plurality of liquid level sensors 142 are vertically spaced and correspond to a plurality of vertically spaced battery packs 120. It is understood that the liquid level sensor 142 corresponding to the battery pack 120 under a level two fire alarm signal transmits the sensed water level signal to the control unit 150. The computer within the control unit 150 compares the measured water level signal with a set signal (the set signal being the height of the battery pack under a level two fire alarm signal), calculates the deviation, and then, based on the nature of the deviation, issues open and close commands to the first control component 1311 to ensure that the battery compartment 111 reaches the set water level sufficient to submerge the battery pack 120 under a level two fire alarm signal.

[0057] For example, the installation height of the liquid level sensor 142 is higher than the installation height of the corresponding battery pack 120, so that the coolant entering the battery compartment 111 can submerge the battery pack 120 under the secondary fire alarm signal, thereby improving the cooling or fire extinguishing effect on the battery pack 120.

[0058] In other embodiments, the monitoring unit 140 may also be implemented as a battery management system (BMS). It is understood that the battery management system can collect the temperature of each battery pack 120 in real time. Thus, the first-level fire alarm signal is triggered when the temperature of one of the battery packs 120 becomes abnormal, while the second-level fire alarm signal is triggered when the temperature of the battery pack 120 that experienced the abnormality remains abnormal even after being sprayed with coolant for a certain period.

[0059] For example, the control unit 150 is also configured to determine the fire situation based on the environmental information monitored by the monitoring unit in order to select whether to continue or stop the fire suppression action.

[0060] As further exemplarily, in response to a persistently abnormal battery pack 120 not being located at the top of its group of battery packs 120, when performing the fire suppression action, the abnormal distribution of the group of battery packs 120 is obtained based on the real-time environmental information, and it is determined whether the fire is spreading upwards; if it is spreading, the fire suppression action continues until all abnormal battery packs 120 are suppressed.

[0061] As further exemplarily, the control unit 150 is also configured to control the first control component 1311 to maintain the spraying fire extinguishing action of the branch pipe 1322 on the abnormal battery pack 120 that has not been submerged when the fire extinguishing action is executed; wherein, the first control component 1311 and the second control component 1323 are controlled to coordinate the flow between the first pipe body 131 and the second pipe body 132 to achieve the submersion speed higher than the spread speed.

[0062] As further exemplarily, the control unit 150 is also configured to control the first control component 1311 to maintain the spraying fire extinguishing action of the spray nozzle 13201 on the abnormal battery pack 120 that has not been submerged when the fire extinguishing action is executed.

[0063] For example, when one of the battery packs A malfunctions and the monitoring unit 140 issues a corresponding Level 1 fire alarm signal, the control unit 150 controls and activates the branch pipe 1322 corresponding to battery pack A to perform a liquid spraying fire extinguishing action on the malfunctioning battery pack A. At this time, if battery pack B in the remaining battery packs 120 also malfunctions and is detected by the monitoring unit 140, issuing a corresponding Level 1 fire alarm signal, the control unit 150 then controls and activates the branch pipe 1322 corresponding to battery pack B to perform a liquid spraying fire extinguishing action on the malfunctioning battery pack B.

[0064] Similarly, it is understandable that when the monitoring unit 140 issues a corresponding level-two fire alarm signal for the abnormal battery pack A1, the control unit 150 controls and connects the filling port 13101 to inject coolant into the battery compartment 111 and submerge the continuously abnormal battery pack A1. At this time, if the battery pack B1 located below the battery pack A1 becomes abnormal (regardless of whether it is a level-one or level-two fire alarm signal), the control unit 150 will not respond because the battery pack B1 is about to be or has already been submerged by the coolant, so no fire-fighting measures are required.

[0065] However, if battery pack B2 located above battery pack A1 malfunctions and issues a Level 1 fire alarm signal (i.e., the fire is spreading upwards), the control unit 150 controls and activates the branch pipe 1322 corresponding to battery pack B2 to perform a liquid spraying fire extinguishing action on the malfunctioning battery pack B2. If battery pack B2 continues to malfunction and issues a Level 2 fire alarm signal, the control unit 150 controls and increases the flow rate of the filling port 13101 (or increases the power of the second infusion pump, or simultaneously opens multiple branch pipes 1322 on the second pipe body 132) to accelerate the injection of coolant and shorten the time required to submerge the malfunctioning battery pack B2 above, thereby improving fire-fighting efficiency.

[0066] It should be noted that when the battery pack 120, which corresponds to a Level 1 fire alarm signal, is located at the top, the control unit 150 controls and activates the spray nozzle 13201 corresponding to the abnormal battery pack 120 to perform a spray fire extinguishing action on the abnormal battery pack 120. When the battery pack 120 remains abnormal, the control unit 150 controls and activates the filling port 13101 to perform a flooding fire extinguishing action, filling the battery compartment 111 with coolant until it submerges the abnormal battery pack 120.

[0067] It should be noted that the suffixes A, B, A1, B1, B2, etc. of the battery pack in the above content are added only for the purpose of clearly expressing the content, and are not actual reference numerals in the attached drawings of the battery pack 120.

[0068] Figure 4The diagram shown is a structural schematic of a first tube body implemented as multiple units in one embodiment of this disclosure. Figure 4 In this example, multiple first tubes 131 are implemented. The two ends of the multiple first tubes 131 are respectively connected to the water storage tank and the battery compartment 111.

[0069] Exemplarily, a plurality of the first tubes 131 are conditionally switched on. The condition can be implemented as the number or height of the battery packs 120 that issue a secondary fire alarm signal. For example, when the monitoring unit 140 detects that at least two or three of the plurality of battery packs 120 are malfunctioning and issuing a secondary fire alarm signal, the control unit 150 switches on the filling ports 13101 of the plurality of first tubes 131 to accelerate the filling speed of coolant into the battery compartment 111, thereby rapidly submerging the battery packs 120 that have issued the secondary fire alarm signal.

[0070] In other embodiments, the filling speed of coolant into the battery compartment 111 can also be accelerated by increasing the diameter of the first tube 131 or adjusting the power of the first infusion pump.

[0071] Figure 5 The diagram shown is a structural schematic of the second tube in another embodiment of this disclosure. Figure 5 In the example, the branch pipe 1322 located between adjacent battery packs 120 forms multiple liquid spray nozzles 13201 corresponding to each battery pack 120 at its upper and lower ends. Exemplarily, in response to the monitoring unit 140 issuing a Level 1 fire alarm signal indicating an abnormality in the battery pack 120, the control unit 150 activates the liquid spray nozzles 13201 on both the upper and lower sides of the abnormal battery pack 120. This allows for the spraying of coolant above and below the abnormal battery pack 120, thereby improving the fire extinguishing and cooling effect.

[0072] Understandable, Figure 5 Each of the spray nozzles 13201 in the example is provided with a second control component that is electrically connected to the control unit 150.

[0073] It should be noted that, Figure 4 The embodiments shown can be compared with Figure 5 The embodiments shown are implemented in combination.

[0074] Figure 6 The diagram shown is a structural schematic of the second tube in yet another embodiment of this disclosure. Figure 7 The middle is shown as Figure 6 A schematic diagram of the cooling component in the example. Figure 6 and Figure 7In the example, the fire-fighting assembly 130 also includes a plurality of cooling elements 133. The number of cooling elements 133 is adapted to the number of spray nozzles 13201. Each spray nozzle 13201 is connected to a cooling element 133, for example, the spray nozzle 13201 is connected to the bottom of the cooling element 133. The cooling element 133 includes an upward-facing cooling cavity 13301, and the battery pack 120 is disposed within the cooling cavity 13301 with a gap between it and the cavity wall of the cooling cavity 13301.

[0075] For example, the battery pack 120 is disposed submerged in the cooling cavity 13301. That is, the battery pack 120 is disposed in the cooling cavity 13301 with a gap between it and the top wall of the cooling element 133.

[0076] Those skilled in the art will understand that when the control unit 150 responds to the monitoring unit 140 issuing a first-level fire alarm signal indicating an abnormality in the battery pack 120, it activates the liquid injection port 13201 of the corresponding abnormal battery pack 120, so that coolant is injected into the cooling chamber 13301 and submerges the battery pack 120, thereby achieving cooling and temperature reduction of the abnormal battery pack 120.

[0077] Preferably, the coolant continuously flows into the cooling element 133 where the malfunctioning battery pack 120 is located until the battery pack 120 within the cooling element 133 returns to normal. Those skilled in the art will understand that continuously maintaining low-temperature coolant in contact with the malfunctioning battery pack 120 prevents the coolant within the cooling element 133 from reducing its cooling effect on the malfunctioning battery pack 120 due to temperature increases.

[0078] For example, the shape of the cooling element 133 is adapted to the shape of the battery pack 120. For example, in this embodiment, the battery pack 120 is rectangular, and the cooling element 133 is also rectangular.

[0079] For example, the cooling element 133 is made of an insulating material, such as ceramic, glass, mica, quartz, epoxy resin, phenolic resin, etc.

[0080] It should be noted that, Figure 4 The embodiments shown in the document can also be used with Figure 6 and Figure 7 The embodiments shown are implemented in combination.

[0081] Back to Figure 2In the example, the fire-fighting component 130 further includes a third pipe 134 for connecting the battery compartment 111 and an external device storing coolant. The third pipe 134 includes a drain port 13401 located at the bottom of the battery compartment 111, and a third control component (not shown) electrically connected to the control unit is located within the drain port 13401. A third infusion pump (not shown) is mounted on the third pipe 134. Thus, when the battery pack 120 returns to normal operation or when a faulty battery pack 120 needs repair or replacement, the control unit first activates the third control component, then starts the third infusion pump to draw the coolant from the battery compartment 111 to the external device. The coolant flowing back to the external device can be reused to reduce fire-fighting costs.

[0082] Figure 8 The diagram shown is a structural schematic of a computer device according to an embodiment of this disclosure. Figure 8 In this example, the computer device 200 includes a bus 210, a processor 220, and a memory 230. The processor 220 and the memory 230 can communicate with each other via the bus 210. The memory 230 can store program instructions. The aforementioned control unit can be implemented by the computer device 200. The processor 220 implements the previous embodiments by running the program instructions in the memory 230. Figure 3 The steps of the control unit 150 in the above.

[0083] Bus 210 can be a Peripheral Component Interconnect (PCI) bus 210 or an Extended Industry Standard Architecture (EISA) bus 210, etc. Bus 210 can be divided into address bus, data bus, control bus, etc. For ease of representation, although... Figure 8 The bus 210 is represented by a single thick line, but this does not mean that there is only one bus 210 or only one type of bus 210.

[0084] In some embodiments, the processor 220 may be implemented as a central processing unit (CPU), a microprocessor unit (MCU), a system-on-chip (System-on-Chip), or a field-programmable array (FPGA). The memory 230 may include volatile memory for temporary data storage during program execution, such as random access memory (RAM).

[0085] The memory 230 may also include non-volatile memory for data storage, such as read-only memory (ROM), flash memory, hard disk drive (HDD), or solid-state disk (SSD).

[0086] In some embodiments, the computer device 200 may further include a communicator 240. The communicator 240 is used for communication with external devices. In specific examples, the communicator 240 may include one or more wired and / or wireless communication circuit modules. For example, the communicator 240 may include one or more of, for example, a wired network card, a USB module, a serial interface module, etc. The wireless communication protocols followed by the wireless communication module include, for example, Nearfield Communication (NFC) technology, Infrared (IR) technology, Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time-Division Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), Bluetooth (BT), Global Navigation Satellite System (GNSS), etc.

[0087] In summary, this disclosure provides an energy storage system with intelligent fire-fighting functionality based on supramolecular halogenated hydrocarbon extinguishing media, comprising a housing, at least one set of battery packs, fire-fighting components, a monitoring unit, and a controller. The housing includes a battery compartment. At least one set of battery packs is spaced apart in the battery compartment along a vertical direction. The fire-fighting components include at least one first pipe and a second pipe connected to an external device storing coolant; the at least one first pipe includes a filling port connecting to the battery compartment, and the second pipe includes multiple spray nozzles corresponding to each battery pack. The monitoring unit is located in the battery compartment and is used to monitor environmental information. The control unit is electrically connected to a first control component of the at least one first pipe, a second control component of the second pipe, and a monitoring unit. In response to receiving a Level 1 fire alarm signal indicating a battery pack malfunction from the environmental information, the control unit activates at least the spray nozzle corresponding to the malfunctioning battery pack to perform a spray fire extinguishing action on the malfunctioning battery pack. If the spray fire extinguishing action on the malfunctioning battery pack has already been performed, the control unit, in response to receiving a Level 2 fire alarm signal indicating a persistent malfunction from the environmental information, activates the filling port to perform a flooding fire extinguishing action, filling the battery compartment with coolant until it submerges the persistently malfunctioning battery pack. This disclosure, through the configuration of the first and second pipes, enables the battery pack to be sequentially sprayed for Level 1 fire alarm signals and flooded for Level 2 fire alarm signals for fire extinguishing and cooling. This not only ensures the safety of the battery compartment but also reduces coolant consumption and fire-fighting costs through tiered fire extinguishing and cooling of the battery pack.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
