How To Put Out An Electric Car Fire: Electric car fires, although relatively rare, require unique procedures and precautions for safe handling and extinguishing. Electric vehicles (EVs) use lithium-ion batteries, and fires involving these batteries can be challenging to control due to their high energy density. Knowing how to put out an electric car fire is essential for first responders, EV owners, and anyone who may encounter such a situation. In this guide, we will explore the steps and safety measures involved in handling an electric car fire, emphasizing the importance of safety and proper procedures to minimize risks.
Keep a safe distance from the vehicle, as there is a risk of thermal runaway or explosion in lithium-ion batteries when they overheat or catch fire. Even if the fire appears to be out, continue to monitor the vehicle for any signs of re-ignition. Properly dispose of the damaged electric vehicle once the fire is under control. Electric car manufacturers or dealerships may have procedures in place for this.
Remember that electric car fires are rare, and the risk can be further reduced by following safety guidelines, properly maintaining your electric vehicle, and promptly addressing any issues or damage that may arise.
What do you use on an electric car fire?
Several approaches have been tested all over the world, from dumping the car into container of water to covering the car with foam or a large fire blanket. The most common solution (at present) is to use copious amounts of water to cool down the battery material.
Class D Fire Extinguisher: If available, a Class D fire extinguisher specifically designed for metal fires, including lithium fires, can be used to attempt to control the fire from a safe distance. These extinguishers typically use dry powder agents, such as powdered graphite or sodium chloride, to smother the fire.
Do Not Use:
Water: Water should never be used on an electric car fire. Water is a conductor of electricity, and spraying water on a high-voltage lithium-ion battery can create additional hazards, such as electrical shock and the potential for thermal runaway. Water can react with the battery materials, causing further complications.
Foam or Carbon Dioxide (CO2) Extinguishers: While these extinguishers are effective for some types of fires, they are not suitable for lithium-ion battery fires in electric vehicles.
Dry Chemical (ABC) Extinguishers: Standard dry chemical extinguishers, often labeled as “ABC” extinguishers, are not recommended for electric car fires because they may not effectively control the type of fire produced by a lithium-ion battery.
Approaching Too Closely: Always maintain a safe distance from the electric car fire. Lithium-ion batteries can pose a risk of thermal runaway or explosion when overheated or on fire.
How do you prevent an EV battery fire?

What is the main reason for electric vehicles burning?
One of the main reasons for an EV fire is an overheated battery back. To prevent this, try the following: Charge the battery up to the 80% mark only. When the battery is charged too much, it gets very heated.
Battery Damage: Damage to the lithium-ion battery pack, which is the heart of an electric vehicle, is a significant factor. This damage can result from accidents, collisions, or punctures to the battery cells. A compromised battery can overheat and lead to a fire.
Overcharging or Incorrect Charging: Overcharging an EV’s battery or using an incompatible or damaged charging cable can cause the battery to overheat, potentially leading to a fire. Follow the manufacturer’s charging guidelines and use certified equipment.
Defective Battery Cells: In some cases, manufacturing defects or flaws in individual battery cells can lead to thermal runaway—a chain reaction of overheating and fires within the battery pack.
High-Speed Impact: High-speed accidents or collisions can result in severe damage to an EV, including the battery pack. This damage can create conditions for a fire to occur.
Excessive Heat: Extreme environmental temperatures, such as extremely hot weather, can lead to overheating of the battery. This can happen if the battery’s cooling system is inadequate or if the vehicle is exposed to prolonged high temperatures.
What causes EV battery explosion?
There are several reasons that can cause a fire in an EV, but the majority of cases are due to a fault or defect in the battery design, abuse of one or more battery cells (by overheating, crushing, penetration, or overcharging), or as a result of a collision.
Overheating: The most common trigger for thermal runaway is excessive heat. High temperatures can be caused by external factors like hot weather or internal factors like rapid charging, overcharging, or aggressive driving that puts excessive demand on the battery.
Physical Damage: Physical damage to the battery cells, such as a puncture or significant impact, can expose the internal components of the battery to air and moisture, which can lead to overheating and thermal runaway.
Manufacturing Defects: Rarely, manufacturing defects or flaws in individual battery cells can initiate thermal runaway. These defects may include impurities in the materials or faulty assembly.
Overcharging: Charging an EV beyond its recommended state of charge can stress the battery and lead to overheating. Overcharging can occur if charging equipment is malfunctioning or if the charging process is not properly managed.
External Fires: In the event of a separate external fire, such as a collision or fire involving another vehicle, the heat from the external fire can potentially reach the EV’s battery and trigger thermal runaway.
Are electric car batteries safe?
The Lithium-ion battery is combustible and can catch fires, it has power cells that can cause short-circuiting if it is damaged. However, lithium-ion batteries have a much lower risk of fire explosions than gasoline in conventional vehicles.
