EV Fires part 2

2023-12-06

Electric vehicle fires: There have been a number of high-profile fires involving electric vehicles (EVs) in 2023. These fires have raised concerns about the safety of EVs. However, experts say that EVs are no more likely to catch fire than gasoline-powered vehicles. The National Fire Protection Association (NFPA) reports that there were 1,310 fires involving passenger vehicles in 2021, of which 190 involved EVs.

While electric vehicles (EVs) offer several environmental and safety benefits compared to traditional gasoline-powered vehicles, they also pose unique fire risks. Lithium-ion batteries, which power most EVs, are highly flammable and can release toxic fumes when they overheat or catch fire.

EV Fire Statistics

According to a 2023 study by the National Fire Protection Association (NFPA), EVs are involved in about 25 fires per 100,000 vehicles sold, compared to 1,530 fires for gasoline-powered vehicles. This means that EVs are about 61 times less likely to catch fire than gasoline-powered vehicles.

EV Fire Causes

The most common causes of EV fires include:

  • Battery issues: Faulty or damaged batteries can overheat and catch fire. This is the most common cause of EV fires.

  • Charging issues: Improper or faulty charging can also cause EV fires. This is because charging can generate heat, which can ignite a flammable vapor that builds up inside the battery.

  • Accidents: EV fires can also be caused by accidents, such as collisions or rollovers. These can damage the battery and cause it to overheat or catch fire.

EV Fire Safety

Despite their higher risk of fire, EVs are designed with several safety features to minimize the risk of fires. These features include:

  • Multiple battery cells: EVs have multiple battery cells, which are designed to prevent fires from spreading from one cell to another.

  • Temperature sensors: EVs have temperature sensors that monitor the battery temperature and can shut down charging or even the vehicle if the temperature gets too high.

  • Fire suppression systems: Some EVs have fire suppression systems that can automatically extinguish fires in the battery.

EV Fire Response

Firefighters are trained to respond to EV fires differently than gasoline-powered vehicle fires. They use special extinguishing agents that are designed to suppress battery fires without causing further damage to the battery or the environment.

EV Fire Prevention

Owners of EVs can take several steps to prevent fires:

  • Park in well-ventilated areas: Do not park EVs in enclosed garages or other areas with poor ventilation.

  • Avoid charging the battery in high heat or cold: Charging in extreme temperatures can put the battery at risk of overheating.

  • Use only the manufacturer's approved charging equipment: Using non-approved charging equipment can increase the risk of fire.

  • Be aware of battery warnings: If you see any warning lights or messages on the dashboard about the battery, take it to a qualified EV service center immediately.
