Fire extinguishing methods for Tesla and GM electric vehicles

The fire extinguishing method of Tesla and General Electric cars: lithium batteries! Traditional fire fighting equipment and technology can prevent traditional car fires. Then the electric vehicle carrying a large number of high-voltage batteries is assumed to be exposed to fire or there is a danger of explosion, because the electrolyte in the battery unit is flammable and can burn flexibly under flame exposure. How can it be stored more safely? What to look for ? Look at the recommendations of Tesla and General Motors. The Tesla Emergency Rescue Manual’s guidelines for electric vehicle fire rescue are as follows: 1. If the flame does not spread to the high-voltage battery due to a small fire, carbon dioxide or ABC dry powder can be used to preserve the battery. When thoroughly inspecting the fire, do not touch any high-voltage components and always check with insulation. 3. The gas cylinder, gas column and other parts can reach the temperature of jubilant liquid expansion and steam explosion. Before inspecting the accident hot zone, it should be dismantled and provided with appropriate precision protection. 4. Assuming that the high-voltage battery is bent, deformed, damaged, or in short, becomes disgraceful in a fire, and it may be suspected of a problem with the battery. Therefore, water conservation should not be too little, and there must be a satisfactory amount of fire-fighting water. 5. It may take up to 24 hours for the battery to stop completely on fire. The use of a thermal imaging camera can ensure that the high-voltage battery is completely cooled before the end of the accident. Assuming there is no thermal imaging camera, the battery must be monitored for re-ignition. The smoke indicates that the battery is still hot, and the monitoring always continues until at least one hour after the battery stops smoking. 6. If law enforcement personnel or haulers do not know this method, there is also a risk of reigniting. The battery is in danger of being burnt to ashes from head to toe. In the past, ModelS electric cars were swallowed by water, caught fire, or after being hit, their high-voltage batteries were damaged and placed less than 50 feet away from exposed open-air areas. Warning 1: In case of fire, please do not touch any part of the vehicle, so as not to affect the power supply. Wear personal protective equipment, including self-contained air breathing apparatus. Warning 2: Always assume that all high-voltage components are energized! Cutting, crushing or touching high-voltage components can cause serious damage or death. The General Motors Volt emergency rescue manual guides how electric vehicles can escape from a fire: assuming that the battery reaches a satisfactory high temperature, the electrolyte leaks and releases, and the electrolyte must be flammable. This requires a lot of water to cool and revive the battery. Since the DC and communication systems are not grounded, firefighters can safely use water as an important resuscitator without the risk of electric shock. The ABC dry powder resuscitator will not suspend the battery flame. During the operation of resuscitating or releasing any high-voltage components, firefighters should prevent direct internal contact, otherwise electric shock may result. In short, after ensuring that firefighters and other rescuers know the technology and operation of electric vehicles, they must be brought back to life, which emphasizes the importance of safety training. Firefighters should also use appropriate personal protective equipment and self-contained breathing apparatus to protect themselves from the heat and prevent inhalation of toxic substances from burning car parts. According to the first to know about the power grid, the Society of Automotive Engineering of my country, together with the Fire Research Institute of the Ministry of Public Security, began to inquire at the early stage of the test. The practice of dry powder foam and other rescue agent bases cannot stop battery fires. When useful rescue agents are selected , It still takes time to test and verify. Study and promote the fire protection standards and the condition of fire protection facilities and equipment for buses and charging stations. The automatic recovery system of the battery pack is also under development, and it must be handled at any time, and there is actual relevant experience.
