Electric vehicles are everywhere these days, especially here in California. From carpool lanes to freeway lanes along I-5, I-10, I-405, and SR-91, thousands of electric vehicles can be found driving across California every day. There are countless benefits to owning an electric vehicle. However, fires and explosions can occur if someone is in a collision or a defect or failure in the battery causes it to malfunction, causing electric vehicle battery fires and explosion injuries.
Why Electric Vehicle Battery Fires Are Different
As more people switch to driving electric, California residents should know about EV battery fires and explosions. Not only can it help motorists keep themselves safe, but it could also allow car accident victims to make informed decisions if they are involved in a collision. When most people think of vehicle fires, they think of gasoline-powered cars. Electric vehicles don’t use gasoline to power their engine, which means they use lithium- ion batteries to store power.
Electric vehicles contain large amounts of stored energy in a small space, which can lead to various problems if someone is in an accident. Damage to an electric vehicle can cause what is called a thermal runaway.
Thermal runaway is when damage, overheating, or a defect causes battery cells to heat up and produce more heat. Once a certain temperature is met, the battery can catch fire, emit flammable gases, and even explode. If someone is fortunate enough to put out an EV battery fire, it can reignite hours or even days later. This makes electric vehicle fires hard to manage for first responders and recovery teams.
Lithium-ion batteries burn differently than a traditional vehicle fire. Fires may require more water and different techniques to extinguish. Since 2011, there have been approximately 198,000 lithium-ion battery fires in 5,718 fires involving electric vehicles and plug-in hybrids. Fires from plug-in electric vehicles are increasing at a rate of roughly 45% annually.
Common Causes of Electric Vehicle Battery Fires
Electric vehicle issues do not always result in fire or explosion. However, there are times when certain factors can increase the risk. An electric vehicle catching fire is most frequently due to damage to its battery cells, leading to a blaze. Severe impacts can cause damage to the vehicle and battery protection systems that prevent the battery from overheating.
Sometimes serious crashes can leave the outside of the vehicle intact while the battery suffers severe damage. Other causes can include:
- Battery defect
- Charging system malfunction
- Electrical system defect
- Faulty repair
- Extreme heat exposure
- Flood water damage
In some explosion cases, vehicles have caught fire without being in an accident. During these investigations, professionals look into whether a defect in the battery design, manufacturing process, or malfunctioning equipment caused the fire.
Steps to Take After Your Vehicle Battery Catches Fire
You’re never truly prepared when your car ignites, especially if you suffered serious injuries in the crash. Seeking medical treatment should be your first concern. Some injuries can take days or weeks to show symptoms. If you were injured in a crash that caused your EV battery to catch fire, be sure to:
- Document the scene
- Save pictures
- Get witness information
- Save all medical bills and information related to the crash
- Do not try to clean your vehicle
Like with any vehicle, electric vehicles are constantly changing and improving. As technology advances, there may be safety concerns, electric vehicle problems, and legal issues that we haven’t even thought of. While electric vehicles are great for our economy and the environment, drivers should always be aware of the danger that batteries pose.
Hire a Car Accident Lawyer
If your electric vehicle catches fire, you may want to hire a car accident lawyer. Fires involving electric vehicles can be complicated and require knowledge of batteries and electricity. Cars these days are very technical and require investigation to determine if there was a defect in the battery design, manufacturing process, or if a part was recalled that may have caused the fire.
There can be multiple parties that could be held liable in these types of accidents, from other drivers to car manufacturers, repair shops, and parts suppliers. A California car accident attorney can help you understand the many legal claims you may have after your electric vehicle catches fire.
FAQs
Are Electric Vehicles More Likely to Catch Fire in an Accident?
According to research done so far, EVs are not more prone to catching fire than conventional cars with gasoline engines. Fires in EV batteries present different challenges because lithium-ion batteries burn at higher temperatures and can reignite. Fires can occur depending on the damage to the battery and surrounding systems after a crash.
What Are Most Car Accidents Caused By?
Many studies reveal that driver error causes most motor vehicle accidents. Some examples of driver-related accidents include distracted driving, speeding, driving under the influence of drugs or alcohol, driving while sleepy, tailgating, and failing to yield right-of-way. Roadway conditions and vehicle defects may contribute to some accidents but are not typically considered to be the primary cause.
What Happens to Electric Car Batteries in an Accident?
Electric vehicle batteries are normally encased in reinforced materials with additional safety precautions to help avoid damage. In severe crashes, battery cells can be damaged, leading to electrical shorts, melted batteries, or thermal events. Some damage may not be visible to the naked eye. For that reason, electric vehicles require extra inspection after a collision if the battery may have sustained damage.
What Is the Most Common Cause of Vehicle Fires, Electrical Failure, Collisions, and Mechanical Failure?
Mechanical breakdown and malfunction are thought to be responsible for the majority of vehicle fires. Engine fires, fuel system problems, overheated parts, and maintenance failures can lead to thousands of vehicle fires annually. Short circuits and failed components also commonly start fires. Electrical problems cause thousands of fires each year.
