Description

Technical Field

[0001] The present invention relates to the field of fire protection technology, and in particular to a control method for an automatic fire extinguishing system in a charging and parking area of ​​a new energy vehicle. Background Art

[0002] The danger of fire in new energy vehicles (such as electric vehicles) mainly stems from the chemical properties of their core components, lithium batteries, and high-voltage electrical systems. They are characterized by highly concealed fires, fast burning speeds, difficulty in extinguishing fires, high risk of re-ignition, and many derivative hazards.

[0003] Currently, most new energy vehicles require charging at charging stations, and the firefighting equipment in parking spaces with charging stations still uses the same standards as for gasoline vehicles. If a new energy vehicle in a single parking space experiences a thermal runaway fire, the ignition point for new energy vehicles is the lithium battery within the vehicle, which is highly susceptible to explosive combustion within a short period of time. Current firefighting equipment, typically using sprinkler-type fire extinguishing technology, primarily uses water mist or streams to extinguish fires. This is ineffective against fires in new energy vehicles, and the fire can easily ignite surrounding vehicles through heat radiation, creating a "chain reaction" and causing significant property damage to vehicle owners and public facilities. Therefore, existing parking spaces for new energy vehicles struggle to effectively extinguish fires at all stages of a new energy vehicle fire. Summary of the Invention

[0056] See also Figure 1 , Figure 1 The present invention provides a flow chart of a method for controlling an automatic fire extinguishing system for a new energy vehicle charging and parking area according to an embodiment of the present invention.

[0057] A control method for an automatic fire extinguishing system for a new energy vehicle charging and parking area according to an embodiment of the present invention is applied to an automatic fire extinguishing system for parking spaces of new energy vehicles. The automatic fire extinguishing system for parking spaces of new energy vehicles is configured with an under-vehicle fire detector 30 and a fire extinguishing module 20 in each parking space 50. The control method comprises the following steps:

[0058] S100 , acquiring detection signals collected by the under-vehicle fire detectors 30 of each parking space 50 in real time.

[0059] There are typically multiple parking spaces 50 for new energy vehicles. In this embodiment, each parking space 50 is equipped with an under-vehicle fire detector 30 and a fire extinguishing module 20. The under-vehicle fire detector 20 can read environmental parameters in real time, independently detecting fire conditions in each parking space 50. It can also be used to formulate more efficient and appropriate firefighting measures based on different environmental parameters.

[0060] In a specific embodiment, the under-vehicle fire detector 20 includes a composite fire detection sensor that can detect ambient temperature, smoke concentration, combustible gas (such as H2, CH4, etc.) concentration, etc., and output temperature signals, smoke concentration signals, combustible gas concentration signals, etc. to achieve accurate fire monitoring.

[0061] S200: When it is determined that the detection signal is a fire detection signal, the parking space 50 where the current fire is located, the alarm level, and the fire extinguishing strategy are determined according to the fire detection signal.

[0062] Please combine Figure 2 In this embodiment, the automatic fire extinguishing system for parking spaces of new energy vehicles of this embodiment forms a fire monitoring mechanism with one master and multiple controls.

[0063] Specifically, multiple parking spaces 50 are divided into different fire monitoring areas. When a new energy vehicle in a parking space 50 burns, the surrounding temperature and some gas concentrations will change. The undercar fire detector 30 on the parking space 50 will capture the changes in the surrounding environment in the first time, output a fire detection signal, and then determine the parking space 50 where the fire is currently located, the alarm level and the fire extinguishing strategy based on the fire detection signal.

[0064] In a specific embodiment, when the detection signal is determined to be a fire detection signal, step S200 determines the parking space 50 where the fire is currently located, the alarm level, and the fire extinguishing strategy based on the fire detection signal, including the following steps:

[0065] S201, when it is determined that the detection signal is a fire detection signal, determining the parking space 50 where the current fire is located based on the location information of the fire detection signal;

[0066] S202, obtaining historical fire data;

[0067] S203, determining the development stage of the current fire according to the fire detection signal and the historical fire data;

[0068] S204: Determine the alarm level and fire extinguishing strategy for the parking space 50 where the current fire is located according to the development stage of the current fire.

[0069] In this embodiment, the fire control unit 40 of the automatic fire extinguishing system for new energy vehicles stores the location information and historical fire data of the undercar fire detectors 30 for each parking space 50. When a detection signal is determined to be a fire detection signal, the unit retrieves the location information and historical fire data of the undercar fire detector 30 that received the fire detection signal. Based on the location information of the fire detection signal, the fire's current parking space 50 is determined. The fire's current development stage, such as the pre-thermal runaway stage, initial stage of thermal runaway, full combustion stage, re-ignition stage, or extinguishment stage, is then determined based on the fire detection signal and historical fire data. The alarm level and fire extinguishing strategy for the parking space 50 currently inhabited by the fire are then determined, enabling precise, zoned fire extinguishing.

[0070] In a specific embodiment, step S204 determines the alarm level and fire extinguishing strategy for the parking space 50 where the current fire is located according to the development stage of the current fire, including the following steps:

[0071] S2041: If it is determined that the current fire development stage is the pre-thermal runaway stage, determine the alarm level of parking space 50 where the current fire is located to be a warning level;

[0072] S2042: If the current fire development stage is determined to be in the early stage of thermal runaway, the alarm level of the parking space 50 where the current fire is located is determined to be level 1, and the fire extinguishing strategy for the parking space 50 where the current fire is located is determined to be local fire extinguishing for the parking space 50 where the current fire is located;

[0073] S2043: If the current fire development stage is determined to be the full combustion stage, the alarm level of parking space 50 where the current fire is located is determined to be level 2, and the fire extinguishing strategy for parking space 50 where the current fire is located is determined to be cross-zone coordinated fire extinguishing for parking space 50 where the current fire is located;

[0074] S2044: If the current fire development stage is determined to be the re-ignition stage, the alarm level of the parking space 50 where the current fire is located is determined to be a level 3 alarm level, and the fire extinguishing strategy for the parking space 50 where the current fire is located is determined to be intermittent cooling extinguishing for the parking space 50 where the current fire is located;

[0075] S2045: If it is determined that the current fire development stage is the extinguishing stage, the alarm level of the parking space 50 where the current fire is located is determined to be the fourth alarm level, and the fire extinguishing strategy of the parking space 50 where the current fire is located is determined to be stopping fire extinguishing.

[0076] In this example, the development of new energy vehicle fires is divided into five stages: pre-thermal runaway, initial thermal runaway, full combustion, re-ignition, and extinguishment. Different alarm levels and firefighting strategies are developed for each fire development stage to improve firefighting effectiveness and efficiency.

[0077] In the pre-thermal runaway stage of new energy vehicles, the lithium battery temperature slowly rises (usually <60°C), the voltage fluctuates abnormally, and there is a trace amount of electrolyte leakage or gas production (such as CO, H2, and other flammable gases). If the undercar fire detector 30 detects one or more of the following: an abnormal increase in the local temperature under the vehicle (such as a rapid increase from room temperature to 120°C) or an increase in the concentration of flammable gases (such as H2, CH4, etc.), the current fire development stage is determined to be the pre-thermal runaway stage, and the alarm level of parking space 50 where the fire is currently located is determined to be the early warning level. An early warning is required and the charging power supply is cut off to prevent further development of the fire.

[0078] In the early stages of thermal runaway in new energy vehicles, a violent chain reaction (such as cathode decomposition and electrolyte combustion) occurs within the lithium battery, generating large amounts of heat, gases (such as CO, H2, CH4), and molten materials (such as electrolyte and electrode materials). The lithium battery casing expands, deforms, and ruptures, spewing out high-temperature flames and "fire rain" (burning electrolyte droplets), and an open flame begins to appear. If the undercar fire detector 30 detects one or more of the following: the local temperature under the vehicle reaches the first-level alarm threshold (such as a temperature greater than 200°C and a heating rate greater than 50°C / min) or a sudden increase in smoke concentration (such as a light obstruction rate greater than 10% / m), the current fire development stage is determined to be in the early stages of thermal runaway, and the alarm level for parking space 50 where the fire is currently located is determined to be the first-level alarm level. The fire extinguishing strategy for parking space 50 where the fire is currently located is to locally extinguish the new energy vehicle fire in parking space 50 to suppress the spread of the fire.

[0079] During the full combustion stage of new energy vehicles, the lithium battery unit is out of control on a large scale, and the fire spreads to the battery pack, the vehicle body structure and surrounding combustibles. The flame is in a jet-like or explosive state, releasing a large amount of heat radiation (heat flux> 25kW / m 2 ), the ambient temperature can reach 800°C to 1200°C. If the undercar fire detector 30 detects that the undercar temperature reaches the secondary alarm threshold (e.g., temperature > 600°C), the smoke concentration reaches the secondary alarm threshold, or the gas concentration reaches the secondary alarm threshold, the current fire development stage is determined to be the full combustion stage, and the alarm level of the parking space 50 where the fire is currently located is determined to be the secondary alarm level. The fire extinguishing strategy for the parking space 50 where the fire is currently located is to conduct cross-zone coordinated fire extinguishing for the parking space 50 where the fire is currently located, that is, to link the fire extinguishing modules 20 of adjacent parking spaces 50 to extinguish the fire.

[0080] During the re-burning stage of a new energy vehicle, the surface open flame appears to be extinguished, but there is still "residual fire" inside the lithium battery (such as incompletely reacted active substances and heat-accumulated battery cells). The ambient temperature drops to 200°C to 300°C, but it may be re-ignited due to contact with air, moisture or mechanical disturbances, and continue to release toxic gases such as CO. If the undercar fire detector 30 detects that the undercarriage temperature reaches the third-level alarm threshold (such as a temperature greater than 150°C and lasts for more than 30 minutes) or the gas concentration reaches the third-level alarm threshold (such as a CO concentration that is continuously higher than the safety value of 300ppm), the current fire development stage is determined to be the re-burning stage, and the alarm level of the parking space 50 where the current fire is located is determined to be the third-level alarm level. The fire extinguishing strategy for the parking space 50 where the current fire is located is to perform intermittent cooling and fire extinguishing for the parking space 50 where the current fire is located, such as periodically spraying fire extinguishing agents to suppress internal chemical reactions.

[0081] During the extinguishing phase of a new energy vehicle, the internal reaction of the lithium battery is completely terminated, with no open flame or heat release, and the temperature drops to ±10°C below the ambient temperature. If the undercar fire detector 30 detects that both the undercar temperature and gas concentration have fallen below the safety threshold, the current fire development stage is determined to be the extinguishing phase, and the alarm level for parking space 50 where the fire is currently located is set to level 4. The fire extinguishing strategy for parking space 50 is to stop extinguishing the fire.

[0082] It is understandable that the specific judgment conditions for each stage can be determined based on fire protection standards and actual local environmental factors, and no specific restrictions are made here.

[0083] In a specific embodiment, the control method further includes:

[0084] The detection signal collected by the under-vehicle fire detector of the parking space 50 where the current fire is located is obtained in real time, and the fire extinguishing strategy is adjusted dynamically.

[0085] In this embodiment, the fire extinguishing effect and efficiency are improved by dynamically adjusting the fire extinguishing strategy.

[0086] S300: According to the alarm level and the fire extinguishing strategy, trigger an alarm linkage and convert the fire detection signal into a corresponding fire extinguishing control signal.

[0087] After determining the alarm level and the fire extinguishing strategy, the alarm is linked and the fire fighting action is executed, and the fire detection signal is converted into a corresponding fire extinguishing control signal and sent to the fire extinguishing module 20 of the parking space 50 where the fire is currently located.

[0088] S400 , according to the fire extinguishing control signal, controlling the fire extinguishing module 20 of the parking space 50 where the current fire is located to automatically extinguish the fire in different areas.

[0089] See also Figure 2-Figure 6 In a specific embodiment, the new energy vehicle parking space automatic fire extinguishing system includes a fire extinguishing agent tank 10, a fire extinguishing module 20 and a fire host control device 40. The fire extinguishing module 20 includes a plurality of horizontal fire extinguishing integrated devices 21 and a plurality of full-coverage fire extinguishing devices 22 connected to the fire extinguishing agent tank 10. The plurality of horizontal fire extinguishing integrated devices 21 are respectively arranged at each parking space 50, and the plurality of full-coverage fire extinguishing devices 22 are respectively arranged above each parking space 50. The under-vehicle fire detector 30 is arranged on the horizontal fire extinguishing integrated device 21. The fire host control device 40 is electrically connected to the under-vehicle fire detector 30, the horizontal fire extinguishing integrated device 21 and the full-coverage fire extinguishing device 22 of each parking space 50.

[0090] The step S400 controls the fire extinguishing module 20 of the parking space 50 where the fire is currently located to automatically extinguish the fire in different areas according to the fire extinguishing control signal, and includes the following steps:

[0091] S401 : According to the fire extinguishing control signal, the horizontal fire extinguishing integrated device 21 and / or the full-coverage fire extinguishing device 22 of the parking space 50 where the current fire is located is controlled to automatically extinguish the fire in different areas.

[0092] In this embodiment, the fire extinguishing agent tank 10 is used to store fire extinguishing agent. The fire extinguishing agent tank 10 may include a pressure storage container, and the fire extinguishing agent includes a lithium battery-specific fire extinguishing agent. Compressed nitrogen is provided in the pressure storage container as a propulsion source, and a spray device controls the discharge of the lithium battery-specific fire extinguishing agent from the pressure storage container. Using a lithium battery-specific fire extinguishing agent can more quickly and effectively control fires than using water, resulting in higher fire extinguishing efficiency.

[0093] The fire extinguishing module 20 includes a plurality of horizontal fire extinguishing integrated devices 21 and a plurality of full-coverage fire extinguishing devices 22 connected to the fire extinguishing agent tank 10. The plurality of horizontal fire extinguishing integrated devices 21 are respectively arranged at each parking space 50. When a new energy vehicle is parked, the horizontal fire extinguishing integrated device 21 is located below the new energy vehicle, and the plurality of full-coverage fire extinguishing devices 22 are respectively arranged above each parking space 50, such as at the position of an awning or at the top of a garage. When a new energy vehicle catches fire, the horizontal fire extinguishing integrated device 30 is close to the fire source and can automatically extinguish the fire below the new energy vehicle in time to control the fire. The full-coverage fire extinguishing device 22 has a large spraying area and can automatically extinguish the fire from above the new energy vehicle to prevent the fire from spreading. The fire extinguishing device of this embodiment is reasonably deployed.

[0094] The fire host control device 40 is electrically connected to the undercar fire detectors 30, the horizontal fire extinguishing integrated device 21 and the full-coverage fire extinguishing device 22 of each parking space 50, forming a one-master-multiple-control fire monitoring mechanism.

[0095] Specifically, multiple parking spaces 50 are divided into different fire monitoring areas. When a new energy vehicle in a parking space 50 burns, it will cause changes in the surrounding temperature and some gas concentrations. The undercar fire detector 30 on the parking space 50 will immediately capture the changes in the surrounding environment and transmit the detection signal to the fire host control device 40. The detection signal includes a fire detection signal and a non-fire detection signal. When the fire host control device 40 determines that the detection signal is a fire detection signal, it determines the parking space 50 where the current fire is located, the alarm level and the fire extinguishing strategy based on the fire detection signal. Then, based on the alarm level and the fire extinguishing strategy, it links the alarm and converts the fire detection signal into a corresponding fire extinguishing control signal. Finally, based on the fire extinguishing control signal, it controls the horizontal fire extinguishing integrated device 21 and / or the full-coverage fire extinguishing device 22 of the parking space 50 to automatically extinguish the fire in different areas. At the same time, the fire host control device 40 can also link the alarm device to issue an alarm, and link the original garage fire extinguishing system to extinguish the fire, making fire prevention and control more effective.

[0096] See also Figure 2In a specific embodiment, the fire extinguishing agent tank 10 and the fire host control device 40 are arranged on one side of all parking spaces 50, and multiple horizontal fire extinguishing integrated devices 21 and multiple full-coverage fire extinguishing devices 22 are longitudinally arranged in the corresponding parking space 50 area.

[0097] In this embodiment, the fire extinguisher tank 10 and the fire control unit 40 are located on one side of each parking space 50, facilitating the delivery of fire extinguisher and the management of the fire extinguishing modules 20 without hindering vehicle access. Multiple horizontal fire extinguishing integrated devices 21 and multiple full-coverage fire extinguishing devices 22 are positioned longitudinally (in the direction of new energy vehicle access) within the corresponding parking spaces 50, facilitating precise fire extinguishing of vehicles in those spaces.

[0098] See also Figure 2-Figure 6 In a specific embodiment, each of the horizontal fire extinguishing integrated devices 21 includes a housing 211, a plurality of first nozzles 212, a first solenoid valve 213, and a first pipeline 214. The housing 211 is arranged at each parking space 50, and the under-vehicle fire detector 30, the plurality of first nozzles 212, and the first solenoid valve 213 are arranged on the housing 211. The plurality of first nozzles 212 are connected to the fire extinguishing agent tank 10 via the first pipeline 214, and the first solenoid valve 213 is electrically connected to the fire host control device 40. Each of the full-coverage fire extinguishing devices 22 includes a plurality of second nozzles 221, a second solenoid valve 222, and a second pipeline 223. The second pipeline 223 is arranged above each parking space 50. The plurality of second nozzles 221 and the second solenoid valve 222 are arranged on the second pipeline 223. The plurality of second nozzles 221 are connected to the fire extinguishing agent tank 10 via the second pipeline 223, and the second solenoid valve 222 is electrically connected to the fire host control device 40.

[0099] The step S401 controls the horizontal fire extinguishing integrated device 21 and / or the full coverage fire extinguishing device 22 of the parking space 50 where the current fire is located to automatically extinguish the fire in different areas according to the fire extinguishing control signal, and includes the following steps:

[0100] S4011 . According to the fire extinguishing control signal, control the first solenoid valve 213 and / or the second solenoid valve 222 of the parking space 50 where the fire is currently located to open.

[0101] In this embodiment, the housing 211 of the horizontal fire extinguishing integrated device 21 is installed in each parking space 50. Housing 211 is equipped with an under-vehicle fire detector 30, a first nozzle 212, and a first solenoid valve 213. The under-vehicle fire detector 30 can detect fires in each parking space 50 in real time. Upon detecting a fire, it transmits a fire detection signal to the fire control unit 40. The fire control unit 40 receives the fire detection signal for that parking space 50 and controls the opening of the first solenoid valve 213 in that parking space 50, allowing the fire extinguishing agent in the first pipeline 214 to be sprayed from the first nozzle 212, achieving automatic zoned fire extinguishing. When the second solenoid valve 222 in the corresponding parking space 50 is controlled to open, the fire extinguishing agent in the fire extinguishing agent tank 10 is transported through the second pipeline 223 and then sprayed from the second nozzle 221. This, in conjunction with the horizontal fire extinguishing integrated device 21, provides precise fire extinguishing control. When the current fire is not serious, only the first solenoid valve 213 or the second solenoid valve 222 may be controlled to open. When the current fire is serious, both the first solenoid valve 213 and the second solenoid valve 222 may be controlled to open.

[0102] An automatic fire extinguishing system for charging and parking areas of new energy vehicles in an embodiment of the present invention is provided with an under-vehicle fire detector 30, a horizontal fire extinguishing integrated device 21 and a full-coverage fire extinguishing device 22 in each parking space 50. The fire host control device 40 receives the fire detection signal collected by the under-vehicle fire detector 30 of each parking space 50, and converts the fire detection signal into a corresponding fire extinguishing control signal to control the horizontal fire extinguishing integrated device 21 and the full-coverage fire extinguishing device 22 of the corresponding parking space 50 to automatically extinguish the fire in a zone. Through the under-vehicle fire detector 30 and the dual fire extinguishing device in each parking space 50, accurate fire monitoring and zoned fire extinguishing are achieved, thereby improving fire extinguishing efficiency.

[0103] In addition, the horizontal fire extinguishing integrated device 21 of this embodiment is small in size and is suitable for both newly installed new energy vehicle parking spaces and for replacing and renovating existing new energy vehicle parking spaces. The housing 211 can be made of metal material, which is economical and efficient.

[0104] In a specific embodiment, there are multiple first nozzles 212, and the shell 211 includes a top surface 2111, a bottom surface and a ring side surface 2112. The top surface 2111 and the ring side surface 2112 are both provided with multiple fire extinguishing holes, and the multiple first nozzles 212 extend from the corresponding fire extinguishing holes respectively.

[0105] In this embodiment, multi-angle fire extinguishing through holes are opened on the shell 211, and multiple first nozzles 212 extend from the corresponding fire extinguishing through holes respectively, so as to realize full-angle spraying of fire extinguishing agent and improve fire extinguishing efficiency.

[0106] In a specific embodiment, the first pipeline 214 includes a first transport pipeline 2141 and multiple first branch pipelines 2142, the first transport pipeline 2141 is respectively connected to the fire extinguishing agent tank 10 and communicates with multiple first branch pipelines 2142, the first solenoid valve 213 is arranged at the connection between the first transport pipeline 2141 and the multiple first branch pipelines 2142, and the multiple first branch pipelines 2142 are arranged inside the shell 211 and connected to the corresponding first nozzles 212.

[0107] In this embodiment, when the first solenoid valve 213 of a certain parking space 50 is controlled to open, the fire extinguishing agent in the fire extinguishing agent tank 10 is transported to the multiple first branch pipelines 2142 through the first transport pipeline 2141, and then sprayed from the multiple first nozzles 212, and the fire extinguishing control is precise.

[0108] In a specific embodiment, the ring side surfaces 2112 are all sloped surfaces, and the top surface 2111 and the ring side surfaces 2112 are both provided with a plurality of air holes 215 .

[0109] In this embodiment, the side surfaces 2112 of each housing 211 are sloped. This slope enhances collision resistance and significantly reduces rebound forces, whether for pedestrians stepping on or vehicles running over the horizontal fire extinguishing integrated device 21. Furthermore, the housing 211 is thick and features ventilation holes 215, which protect the internal components while ensuring air circulation inside and outside, ensuring the proper functioning of the undercar fire detector 30.

[0110] In a specific embodiment, each second pipeline 223 is provided with a plurality of second nozzles 221 along the longitudinal direction of the parking space 50 .

[0111] In this embodiment, a plurality of second nozzles 221 are arranged on the second pipeline 223 at intervals along the longitudinal direction of the parking space 50, so as to realize the spraying of fire extinguishing agent at multiple positions and improve the fire extinguishing efficiency.

[0112] In a specific embodiment, the control method further includes the following steps:

[0113] Real-time acquisition of detection signals collected by the undercar fire detector 30 in the parking space 50 adjacent to the current fire;

[0114] Determining whether the current fire is spreading;

[0115] If so, the fire extinguishing module 20 controls the parking space 50 where the fire spreads to automatically extinguish the fire in different areas.

[0116] This embodiment determines whether the current fire is spreading by acquiring in real time the detection signal collected by the undercar fire detector 30 in the parking space 50 adjacent to the current fire, that is, whether a fire has occurred in a new energy vehicle in the parking space 50 adjacent to the current fire. If so, the fire extinguishing module 20 in the parking space 50 where the fire is spreading is controlled to perform automatic zoned fire extinguishing to extinguish the fire in the parking space 50 where the fire is spreading, thereby ensuring the safety of adjacent new energy vehicles and reducing fire losses.

[0117] In a specific embodiment, the control method further includes the following steps:

[0118] S500: When it is determined that the detection signal is a fire detection signal, a charging power cut-off signal is sent, where the charging power cut-off signal is used to cut off the charging power of the new energy vehicle parking space charging pile.

[0119] When performing automatic zoned fire extinguishing, this embodiment jointly cuts off the charging power supply of the charging pile in the parking space of the new energy vehicle, prevents the new energy vehicle from overcharging and causing thermal runaway, suppresses the spread of the initial fire, and prevents damage to the charging pile and the vehicle.

[0120] In summary, an embodiment of the present invention provides a control method for an automatic fire extinguishing system for a new energy vehicle charging and parking area, which is applied to an automatic fire extinguishing system for parking spaces of new energy vehicles. The automatic fire extinguishing system for parking spaces of new energy vehicles is equipped with an under-vehicle fire detector 30 and a fire extinguishing module 20 in each parking space. The control method is to obtain the detection signal collected by the under-vehicle fire detector 30 in each parking space in real time. When the detection signal is determined to be a fire detection signal, the parking space where the current fire is located, the alarm level, and the fire extinguishing strategy are determined based on the fire detection signal. Then, based on the alarm level and the fire extinguishing strategy, an alarm is linked and the fire detection signal is converted into a corresponding fire extinguishing control signal. Finally, based on the fire extinguishing control signal, the fire extinguishing module 20 in the parking space where the current fire is located is controlled to automatically extinguish the fire in a zoned manner. By deploying an under-vehicle fire detector 30 and a fire extinguishing module 20 in each parking space and a one-master-multiple-control fire monitoring mechanism, accurate fire monitoring and zoned fire extinguishing are achieved in parking spaces of new energy vehicles, improving fire extinguishing efficiency and effectiveness, and ensuring the property safety of vehicle owners and public equipment.
