Electrical automobile fireplace stories are sometimes exaggerated, however the battery can ignite. And whereas gasoline vehicles are worse than an EV, knowledge suggests hybrid autos are essentially the most in danger.Each few months we see a narrative about an electrical automobile catching on fireplace or that they’re harmful and will spontaneously combust. In case you’re planning to purchase an EV, you’ve seemingly seen the headlines. So, are EVs actually burning down in all places, and are they at a higher threat of catching fireplace? It’s difficult, however the reply is not any.
At this level, most individuals are effectively conscious of the hearth troubles Chevrolet confronted with its Bolt EV line, which it will definitely recalled for over a yr. Plus, that’s simply considered one of many examples in case you do a fast Google search.
Electrical autos are thrilling, new, and vastly completely different than common inside combustion engine (ICE) vehicles. Nevertheless, battery fireplace fears have accompanied the rise of EVs as a complete. So, under we’ll discuss why it’s occurring, the frequency, how common vehicles are worse, and some different particulars for these considering an EV.
Why Are Electrical Automobiles Catching on Hearth?
Electrical autos get energy from Lithium-ion batteries. The identical sort of know-how powers all kinds of units, out of your iPhone, smartwatch, scooter, and laptop computer, or the most recent Tesla. We’ve seen iPhones and Samsung Galaxy units catch on fireplace because of these battery packs, and we’re all aware of stories of hoverboard fires, so it’s not simply EVs.
Nevertheless, electrical vehicles have considerably greater battery packs, high-tech cooling programs to maintain them at excellent temperatures when you drive, and rather more, making them far completely different from the little 5,000 mAh battery in your cellphone.
Battery packs retailer tons of vitality in a small area, and EVs drain the battery quickly. Because of this, EV battery packs can get fairly scorching. Nevertheless, cooling programs maintain all the things in examine. That stated, most EV battery fires are because of defective designs, thermal runaways, a brief circuit, penetration from an accident, or another form of failure.
The Chinese language EV maker Nio stated its fires had been because of a brief circuit. As for the Chevy Bolt EV, GM defined that “GM and LG have recognized the presence of two uncommon simultaneous defects, present in the identical battery cell, made throughout the module manufacturing course of.” Stating the issue is a torn anode tab and folded separator inside the battery module.
With out stepping into too many particulars, it sounds just like the Chevy Bolt EV lithium-ion battery drawback ultimately led to 2 cells touching one another, a brief circuit, main to fireside dangers.
Car Fires by the Numbers
Present estimations recommend that solely round one % of the over 260 million autos on the roads in America are electrical. Clearly, many extra gasoline-powered autos are catching on fireplace than EVs. Evaluating an ICE automobile to EVs is tough, however EV fires aren’t as frequent as you most likely assume.
And whereas we will’t examine the 2 simply, an insurance coverage firm Auto Insurance coverage EZ and a slew of researchers gathered all kinds of fireplace knowledge from the Bureau of Transportation and the Nationwide Transportation Security Board (NTSB) to color a greater image.
The corporate in contrast the variety of fires per 100,000 gas-powered autos offered with the variety of EVs offered, and the outcomes are fairly fascinating.

In keeping with their analysis, gasoline-powered (ICE) autos catch on fireplace way more usually than electrical autos. In actual fact, for each 100,000 vehicles offered, roughly 1,529 caught fireplace.
As compared, for each 100k electrical autos on the street, solely round 25 catch on fireplace, no matter how. I don’t know what I anticipated, however that quantity is far completely different than I imagined it will be.
Nevertheless, it’s essential to notice that the larger drawback is hybrid vehicles. If this analysis is correct, these catch on fireplace greater than twice as usually as common autos. That’s scary.
Gasoline Automobiles Are Really Worse
There are hundreds of thousands and hundreds of thousands of gasoline-powered autos on the street, and people catch on fireplace on a regular basis. In actual fact, in 2021 alone, solely on highways, round 174,000 freeway automobile fires had been reported in america, in line with Statista.
Going by the report talked about above, it seems like common vehicles are way more prone to catch on fireplace than electrical autos, and by a substantial margin. There’s a a lot higher probability that an ICE automobile will burst into flames than an electrical automobile, even throughout an accident. Remember that collisions, whether or not gasoline or electrical trigger most automobile fires, however it’s nonetheless fascinating to see how large the distinction is.
Hybrid Automobiles Prime the Listing

Electrical autos are the massive new factor, which is why they’re all the time within the information, particularly when one catches on fireplace. It’s straightforward to see one other story and assume the worst. That stated, we’re all used to listening to or seeing common vehicles on fireplace, which doesn’t garner the identical headlines.
Nevertheless, that doesn’t imply there isn’t extra to the story. Curiously sufficient, the analysis above means that hybrid autos catch on fireplace quite a bit, excess of you most likely anticipated.
If the graphic above is correct, for each 100,000 hybrid autos offered, round 3,474 caught fireplace. That’s greater than double ICE autos and considerably greater than all-electric autos. Principally, hybrid vehicles ignite essentially the most, and electrical vehicles are the most secure, whereas combustion engine autos are within the center.
And whereas that definitely sounds scary, it is sensible. Hybrid autos have all of the parts of an electrical automobile and an everyday gasoline-powered engine. They’re at double the danger, to not point out all these components are jam-packed into a good area.
In a collision with a hybrid, the automobile is prone to damaging the gasoline tank or the battery system. Plus, there are seemingly extra electronics, shifting components, and threats of brief circuits and issues of that nature.
Any automobile can catch on fireplace given the proper circumstances or throughout a foul accident. However when electrical autos catch on fireplace sitting in a driveway, that’s when folks get involved. It’s value mentioning that these conditions are few and much between, however it does occur.
A much bigger drawback is that when EVs do catch fireplace, these fires are harder to extinguish. We’ve even seen stories of electrical automobile fires being put out, towed, then re-igniting later, however that’s a narrative for an additional day. So, why are EVs all the time catching on fireplace? Nicely, they’re not.
In closing, all autos can burst into flames, however electrical vehicles aren’t inherently extra harmful. Like with any new know-how, EVs will evolve, enhance, and advance over time.
