The lithium ion battery has the advantages of high energy density, long cycle life and low self-discharge rate, and has been widely applied to the field of new energy vehicles, in particular to the fields of electric automobiles and novel energy storage. However, when the lithium battery is in an abusive condition such as overcharging, short-circuiting, etc., thermal runaway is very easy to occur, and then the lithium battery is developed into a large-scale fire explosion accident.
Most lithium-based electric vehicles are not provided with fire suppression systems temporarily under the constraint of cost, energy density and other conditions, and when a thermal runaway fire disaster occurs in a parking space or in a charging and discharging process, the traditional building fire protection system is difficult to efficiently suppress open fire, and jet fire is influenced by roof jet or ground bottom jet of a vehicle body to rapidly spread to a side vehicle; meanwhile, a large amount of NO x and other toxic smoke are discharged, which forms a great threat to public safety and life and property safety of people. Existing charging stations and parking spaces are generally provided with portable fire extinguishing devices, but the provided fire extinguishing devices are low in response speed, poor in pertinence and low in automation degree, are difficult to intervene in time and inhibit open fire efficiently when new energy vehicles are in a fire disaster, and cannot effectively reduce the fire hazard of the new energy vehicles in the process of stopping or charging and discharging.
According to the knowledge of the inventor, the research of the special fire alarm and suppression system for the new energy vehicle parking space is less at present, and the system for controlling the fire intervention of the lithium-based new energy vehicle is seriously lacking. The existing fire extinguishing and fire extinguishing system for the new energy parking spaces has the following defects:
(1) The fire-fighting spraying is matched with the hand-held fire extinguisher, so that the system has poor integrity, low automation degree and strong hysteresis, and the unmanned all-weather high-efficiency fire prevention and control can not be realized;
(2) The fire alarm mainly takes traditional smoke sense and temperature sense, so that the fire alarm requirement of the new energy vehicle is difficult to meet, and the false alarm rate is higher;
(3) The traditional mediums such as water, water base, dry powder and the like are mainly used, the inhibition effect on battery fire is limited, and high-efficiency inhibition is difficult to realize;
(4) The medium is released from top to bottom, and is easy to be consumed by smoke and fire plumes in the opposite direction to the flame development direction of the battery, so that point-to-point fire suppression on a fire source is difficult to realize, and the fire extinguishing efficiency is low.
Therefore, the existing fire alarm and suppression system for the new energy vehicle parking space has a plurality of defects, and the system cannot adapt to the rapid development of the new energy vehicle.

When the battery in the battery pack of the new energy automobile is out of control, a large amount of smoke and combustible gas are released, at the moment, the detection and early warning subsystem 1 starts to work, and when three conditions that the smoke concentration sensor 10 detects that the smoke concentration is higher than 1500ppm or the CO concentration is higher than 500ppm or the H 2 sensor 9 detects that the H 2 concentration is higher than 30ppm meet the two conditions, the first-level early warning is triggered, namely the detection and early warning subsystem 1 detects that the battery pack of the new energy automobile is out of control, and the single car fire of the new energy automobile is triggered. At the moment, the detection and early warning subsystem 1 transmits a control signal to the fire extinguishing subsystem 2, and simultaneously transmits fire abnormal information to the vehicle owner mobile terminal to realize online alarm; the fire extinguishing subsystem 2 is divided into a pressure storage type and a non-pressure storage type, and the pressure storage type fire extinguishing system and the non-pressure storage type fire extinguishing system are respectively analyzed in the following specific embodiments. For the pressure storage type fire extinguishing system, the detection and early warning subsystem 1 transmits a control signal to the first electromagnetic valve 23, after the first electromagnetic valve 23 is opened, the fire extinguishing medium 21 stored in the first liquid storage cavity 20 is released through the fire extinguishing spray head 16 under the pushing of the prefabricated nitrogen gas through the conveying pipeline 18, so that full-coverage point-to-point fire extinguishing is realized on the battery pack at the bottom of the new energy automobile, and the thermal runaway fire is restrained in the triggering and developing stage.
It should be noted that a plurality of first liquid storage chambers 20 are provided in the fire extinguishing subsystem housing 19, and different duty cycles, different doses and different simultaneous injections are achieved by the first solenoid valve 23. For a non-pressure storage fire extinguishing system, the detection and early warning subsystem 1 transmits a control signal to the control circuit 25, signals the generator 27 to start the propellant, the propellant 28 generates high pressure through a combustion reaction, and the piston 26 is pushed to release the fire extinguishing medium 21 through the fire extinguishing nozzle 16 through the conveying pipeline 18.
It should be noted that the non-pressure storage fire suppression system carries a plurality 27 of generators, different duty cycles, different doses and different timing of the injections can be achieved by the control circuit 25.
If the haloalkane fire extinguishing agent does not effectively inhibit the open fire of the battery of the new energy automobile or inhibit the re-ignition and the expansion of the fire of the battery in thermal runaway after the open fire, the subsequent secondary early warning and cooling fire-retarding subsystem 3 is started when the fire is rapidly transmitted to the side vehicle. At this time, when the smoke concentration sensor 10 detects smoke with a concentration higher than 2500ppm or the CO sensor 7 detects CO with a concentration higher than 1100ppm or the H2 sensor 9 detects H2 with a concentration higher than 60ppm or the temperature sensor 12 detects temperature higher than 80 ℃ to satisfy the condition that two conditions are satisfied and the flame sensor detects flame, the secondary early warning is triggered, that is, the new energy automobile has flame outside and has the risk of spreading to the side vehicles.
The structure of the cooling fire-retarding subsystem 3 is shown in fig. 4, the detection and early-warning subsystem 1 transmits a control signal to the second electromagnetic valve 33, the water-based fire-extinguishing medium 30 stored in the second liquid storage cavity 29 is released through the fire-extinguishing nozzle 16 under the action of the preset pressure through the conveying pipeline 18, a water curtain is rapidly formed at the side of the new energy automobile, and rapid propagation of the flame of the electric automobile to the side automobile is blocked.
If the fire extinguishing subsystem 2 and the cooling fire retarding subsystem 3 do not effectively inhibit open fire, after firefighters intervene, the fire extinguishing water can be connected into the fire-fighting interface 31, and the fire extinguishing water is more accurately released to a fire point through the conveying pipeline 18 and the fire extinguishing spray nozzle 16, so that point-to-point fire extinguishing is realized, and the efficiency and the success rate of fire rescue can be improved.
The embodiment can quickly respond when the new energy vehicle is out of control and has a fire disaster, and the haloalkane fire extinguishing medium is released in the development stage of the fire disaster to effectively inhibit the battery fire disaster, control the fire condition as early as possible and provide time for fire rescue and personnel escape. The water-based fire-retarding water curtain is released in the stage of spreading and spreading the fire, so that the spread and spread of the fire to the side automobiles are blocked, the fire loss is effectively reduced, and the expansion of the fire scale is prevented; after the fire rescue enters the fire scene, point-to-point inhibition of fire water is realized through the reserved fire interface and the special spray head, and the efficiency of the fire rescue is improved.
