Almost everyone knows that electric vehicles are very different from gasoline vehicles, but there are still many misunderstandings about these battery-powered vehicles. Many people believe that the fire rate of electric vehicles is higher Gasoline cars and electric car battery packs are no different slow-explosive bomb.
Lithium-ion battery fires require extremely large amount of water to cool down. The US National Fire Protection Association said an electric vehicle fire in Texas required more than 113,000 liters of water after an accident. Firefighting forces do not always have tank trucks and equipment available to handle this situation.
In addition, firefighting and rescue forces must follow a different procedure than a gasoline vehicle fire, requiring separate training for electric vehicle fires.
The US National Traffic Safety Committee found that many automakers have specific guidelines. Emergency troubleshooting instructions are incomplete and inaccurate for electric vehicles, but things will gradually change.
As electric vehicles become more popular, manufacturers, lawmakers and Product safety experts may be able to develop a separate set of safety standards for electric vehicles and find measures to deal with vehicle fire incidents.
Electric vehicles have In what cases can a fire occur?
Statistics show that there are two most common types of electric vehicle fires. In some cases, the battery caught fire after a vehicle collision or after the battery was punctured or dented for some reason.
In recent years, car manufacturers have increased the Protect the outside of the battery pack to reduce the risk of impact when a collision occurs with the vehicle.
Other fires that occur while the vehicle is plugged in are situations that have been reported recently. and lead to vehicle recalls that cost manufacturers billions of dollars. Investigation results show that the batteries of the recalled vehicles have defects that increase the risk of fire when charging.
The US government last year spent 118 million USD to the Fire Prevention Research Fund of this country to find the best way to handle electric vehicle fires, but it will not be until September next year that this research will be completed.
Until researchers find the best way to fight electric vehicle fires, what car owners need to do to protect themselves and the community is to follow the principles of using and charging electric vehicles. as well as other devices that use lithium-ion batteries.
The general rule is to use only the appropriate power source and voltage; Do not plug in the charger continuously for more than 8 hours and there must be supervision throughout the vehicle charging process; Do not plug in the charger while starting the engine; Do not arbitrarily change the structure, especially the battery/battery system and charging system.
In buildings, it is necessary to arrange an area specifically for charging electric vehicle batteries in a dry place. Dry and ventilated, away from fire sources, heat sources and flammable objects, tangled networks of electrical wires or many other electronic devices; At the same time, do not arrange the charging sockets too thickly…
