First, electric cars spread fast! At the moment, the power-based lithium-ion battery of the mainstream electric vehicle uses a lithium ion battery, while lithium is the most active metal element, because it has a small size, energy density, and has a cool love of the majority of electric vehicle enterprises. However, it is precisely because of this, lithium elements are also one of the most difficult metal elements after combustion. Once exposed to air, it will be oxidized with oxygen in the air, and there is a violent combustion or even explosion.
And the burning speed is extremely fast, and all the processes can be completed in just a few seconds. In contrast, the self-ignitability of the fuel car is much higher: First, its combustion speed is slow, and after combustion, it is possible to reach the fuel tank and reach the most, when the fire is in the front stage, if the fire is small, use The fire extinguisher can be easily extinguished; secondly, the fuel car self-ignition explosion is not high, it is necessary to reach the flash point and have enough air (ie vaporization, mixed air, reaching the limit of explosion), then encounter a fire to reach the burning point, and accompany it When a certain strong oxidant will explode, the safety of saving the fuel car spontaneous combustion is much higher. Therefore, for the electric car, the most correct solution is:.
If you have already fired, you should immediately stay away from the vehicle. After you find a safe place, please call 119 fireworks. Second, the combustion temperature is too high in addition to the combustion speed, the heat of the lithium-ion battery occurs in combustion, and is also the fuel vehicle.
my country's fire department has done a detection together, igniting a lithium-ion battery electric bicycle, analog battery's fire process. After the detection, the thermal car after burning is up to 604 ¡ã C outdoor. And the fire department is judged, if the indoor burning, its temperature may even reach a giant value of 1200 ¡ã C.
Under the protection of safety facilities, the average person can not be close, otherwise the high temperature is sufficient to make people fatal. Third, the combustion will have a poisonous gas gas does not have any big fire, and the people who really burned to death are not much, and the greater part of the person is carbon dioxide, carbon monoxide and other poisonous gases. The combustion of electric vehicles is no exception: after the lithium-ion battery is burned, there will be strong and pungent toxic toxic to smoke, and the hydrogenide and hydrogen cyanide.
Firefighten analysis, an electric vehicle appeared within a certain range, enough to kill hundreds. Therefore, even if the firefighters go to the fire, we must wear professional gas masks, let alone our hands unarmed civilians? Fourth, it is difficult to extinguish after the fire, there is still a significant feature after the lithium-ion battery burns, it is difficult to be extinguished. It takes 24 hours uninterrupted water (a lot of water) to completely extinguish, and after extinguishing, there will be a certain chance to reset the phenomenon.
It is not necessary to monitor the battery and no longer smoke, and the time is more than an hour. Perhaps many people will feel that the circuit can't use water, but the power lithium-ion battery is an exception, and the power lithium-ion battery does not only want water, but also a lot of water: if the fire is small, there is no spread to the battery pack, can be carbon dioxide Or ABC dry powder fire extinguisher. Once the fire is large, there is more water because the power lithium-ion battery will be bent, deformed, damaged in the fire, if there is too little water, the toxic gas will exude a lot.
For example, in the near future, in order to extinguish the fire, the local fire department has to drop a lot of water, almost looked off the next layer B3 parking lo.
