Electrical automobile fireplace reviews are sometimes exaggerated, however the battery can ignite. And whereas gasoline vehicles are worse than an EV, information 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. For those who’re planning to purchase an EV, you’ve doubtless seen the headlines. So, are EVs actually burning down in all places, and are they at a better threat of catching fireplace? It’s sophisticated, however the reply isn’t any.

At this level, most individuals are nicely conscious of the fireplace 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 should 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, beneath we’ll speak about why it’s occurring, the frequency, how common vehicles are worse, and some different particulars for these excited by an EV.

Why Are Electrical Vehicles Catching on Hearth?

Electrical autos get energy from Lithium-ion batteries. The identical kind of expertise powers all kinds of gadgets, out of your iPhone, smartwatch, scooter, and laptop computer, or the newest Tesla. We’ve seen iPhones and Samsung Galaxy gadgets catch on fireplace because of these battery packs, and we’re all aware of reviews of hoverboard fires, so it’s not simply EVs.

Nevertheless, electrical vehicles have considerably greater battery packs, high-tech cooling methods to maintain them at superb temperatures when you drive, and far more, making them far completely different from the little 5,000 mAh battery in your cellphone.

Battery packs retailer tons of power in a small house, and EVs drain the battery quickly. Consequently, EV battery packs can get fairly sizzling. Nevertheless, cooling methods preserve every little thing in examine. That stated, most EV battery fires are resulting from defective designs, thermal runaways, a brief circuit, penetration from an accident, or another type of failure.

The Chinese language EV maker Nio stated its fires had been resulting from 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 throughout the battery module.

With out entering into too many particulars, it sounds just like the Chevy Bolt EV lithium-ion battery drawback finally 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 automotive to EVs is troublesome, however EV fires aren’t as widespread as you in all probability suppose.

And whereas we are able to’t examine the 2 simply, an insurance coverage firm Auto Insurance coverage EZ and a slew of researchers gathered all kinds of fireside information 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 bought with the variety of EVs bought, and the outcomes are fairly fascinating.

In response to their analysis, gasoline-powered (ICE) autos catch on fireplace much more usually than electrical autos. The truth is, for each 100,000 vehicles bought, roughly 1,529 caught fireplace.

Compared, for each 100k electrical autos on the highway, solely round 25 catch on fireplace, no matter how. I don’t know what I anticipated, however that quantity is way completely different than I imagined it might be.

Nevertheless, it’s necessary 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.

Fuel Vehicles Are Really Worse

There are hundreds of thousands and hundreds of thousands of gasoline-powered autos on the highway, and people catch on fireplace on a regular basis. The truth is, in 2021 alone, solely on highways, round 174,000 freeway automobile fires had been reported in america, in response to Statista.

Going by the report talked about above, it seems like common vehicles are much more prone to catch on fireplace than electrical autos, and by a substantial margin. There’s a a lot better probability that an ICE automobile will burst into flames than an electrical automotive, even throughout an accident. Remember the fact that collisions, whether or not gasoline or electrical trigger most automotive fires, however it’s nonetheless fascinating to see how huge the distinction is.

Hybrid Autos Prime the Record

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 suppose 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. Apparently sufficient, the analysis above means that hybrid autos catch on fireplace quite a bit, excess of you in all probability anticipated.

If the graphic above is correct, for each 100,000 hybrid autos bought, round 3,474 caught fireplace. That’s greater than double ICE autos and considerably greater than all-electric autos. Mainly, hybrid vehicles ignite essentially the most, and electrical vehicles are the most secure, whereas combustion engine autos are within the center.

And whereas that actually sounds scary, it is sensible. Hybrid autos have all of the elements of an electrical automotive 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 house.

In a collision with a hybrid, the automobile is liable to damaging the gasoline tank or the battery system. Plus, there are doubtless extra electronics, transferring components, and threats of brief circuits and issues of that nature.


Any automotive can catch on fireplace given the appropriate circumstances or throughout a nasty accident. However when electrical autos catch on fireplace sitting in a driveway, that’s when folks get involved. It’s price mentioning that these conditions are few and much between, however it does occur.

An even bigger drawback is that when EVs do catch fireplace, these fires are harder to extinguish. We’ve even seen reviews of electrical automobile fires being put out, towed, then re-igniting later, however that’s a narrative for one more 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 expertise, EVs will evolve, enhance, and advance over time.
