Do you have to be nervous about your EV going up in smoke?

Electrical automobile fireplace studies are sometimes exaggerated, however the battery can ignite. And whereas fuel 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 fire 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 danger of catching fireplace? It’s sophisticated, however the reply is not any.
At this level, most individuals are properly conscious of the fireplace troubles Chevrolet confronted with its Bolt EV line, which it will definitely recalled for over a year. Plus, that’s simply certainly one of many examples when you do a fast Google search.
Electrical autos are thrilling, new, and vastly totally 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 discuss why it’s taking place, the frequency, how common vehicles are worse, and some different particulars for these involved in an EV.
Why Are Electrical Vehicles Catching on Hearth?

Electrical autos get energy from Lithium-ion batteries. The identical sort of expertise powers all kinds of units, out of your iPhone, smartwatch, scooter, and laptop computer, or the newest Tesla. We’ve seen iPhones and Samsung Galaxy devices catch on fire due to these battery packs, and we’re all accustomed to studies of hoverboard fires, so it’s not simply EVs.
Nevertheless, electrical vehicles have considerably larger battery packs, high-tech cooling programs to maintain them at splendid temperatures whilst you drive, and far more, making them far totally different from the little 5,000 mAh battery in your telephone.
Battery packs retailer tons of power in a small house, and EVs drain the battery quickly. Consequently, EV battery packs can get fairly scorching. Nevertheless, cooling programs hold every little thing in examine. That stated, most EV battery fires are as a result of 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 as a result 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 throughout the battery module.
With out entering into too many particulars, it sounds just like the Chevy Bolt EV lithium-ion battery downside finally led to 2 cells touching one another, a brief circuit, main to fireplace dangers.
Car Fires by the Numbers

Present estimations counsel 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 troublesome, however EV fires aren’t as frequent as you most likely 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 sorts of fire data 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 accordance with 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 street, solely round 25 catch on fireplace, no matter how. I don’t know what I anticipated, however that quantity is far totally different than I imagined it might be.
Nevertheless, it’s necessary to notice that the larger downside is hybrid vehicles. If this analysis is correct, these catch on fireplace greater than twice as usually as common autos. That’s scary.
Gasoline Vehicles Are Truly Worse

There are tens of millions and tens of millions of gasoline-powered autos on the street, 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 the US, according to Statista.
Going by the report talked about above, it appears like common vehicles are much more more likely to catch on fireplace than electrical autos, and by a substantial margin. There’s a a lot better likelihood that an ICE automobile will burst into flames than an electrical automobile, even throughout an accident. Remember the fact that collisions, whether or not fuel or electrical trigger most automobile fires, however it’s nonetheless fascinating to see how huge the distinction is.
Hybrid Autos High the Checklist
![graphic showing EVs on fire.](https://www.reviewgeek.com/p/uploads/2023/01/0a15605b.jpg)
Electrical autos are the massive new factor, which is why they’re at all times 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. Curiously sufficient, the analysis above means that hybrid autos catch on fireplace loads, excess of you most likely 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 automobile and an everyday gasoline-powered engine. They’re at double the chance, to not point out all these components are jam-packed into a decent house.
In a collision with a hybrid, the automobile is susceptible to damaging the fuel tank or the battery system. Plus, there are doubtless extra electronics, shifting components, and threats of brief circuits and issues of that nature.
Any automobile can catch on fireplace given the suitable 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.
An even bigger downside is that when EVs do catch fireplace, these fires are tougher to extinguish. We’ve even seen studies 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 at all times catching on fireplace? Effectively, 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.
