With more people driving electric vehicles in South Korea, the number electric vehicle fires are also on the up.
To counter the problem, the fire department and Korea Expressway Corporation have come up with ways to effectively extinguish such fires.
Jeong Eun-joo has the details.
Firefighters cover a car that's caught fire with a special blanket.
Once the flames disappear, they sprinkle water over the blanket to cool it down.
As it's an electric car, emergency services would have to use copious amounts of water to distinguish the fire and so have had found an alternative method.
“Usually, water has to be sprayed for up to 72 hours. So we started researching ways to extinguish a fire by using as little water as possible.”
A bigger problem with electric vehicle fires is that they often re-ignite due to overheated batteries.
“There were cases of EVs re-igniting a week later at the scrapyard. An effective way to prevent that would be to immerse the cars in a water tank.”
As there have been cases of EVs catching fire while charging, the Korea Expressway Corporation has built fire extinguishing facilities at highway rest stops.
In the event of a fire, a tube installed on the floor rises 60 centimeters to trap water around the vehicle like a water tank.
This helps prevent secondary fires.
“There are many cases of electric vehicles catching fire while charging. So I thought highway rest areas should also have fire extinguishing facilities and installed them.”
There have already been 44 cases of electric vehicle fires just this year.
But with various extinguishing methods, damage from electric vehicle fires is expected to decrease.

0:58 "Electric vehicle fires often reignite due to overheated batteries", the issue is that the batteries still haved stored energy that is released in an uncontrolled fashion due to thermal runaway. Either have to cool them , 260 degrees (copious amounts of water) or figure out how to drain all residual stored energy (highly dangerous & potentially explosive if not done correctly).
I heard that it can take up to 30 days completely submerged before the fire is out. 😱😱😱😱😱😱😱😱😱😱😱
They said sometimes they reignite after like a week of sitting. Cooling them down isn’t the issue it’s stored energy.
It's also the issue that electric vehicle fires can burn at over 5000 degrees vs an ice car that's usually 1000-2000 degrees, you have a lot more heat to deal with.
Isn’t safety suppose to be first? Imagine the fires inside tunnels and parking garage. Yikes!
Gas cars can catch on fire in a parking garage and tunnel too?
@@user-zd5lz7su9t Yes of course, however they can be extinguished efficiently where as EV’s cannot.
@@slagletoby isn’t that what these ev fire extinguisher are for?
@@brooklyn560 there's not enough and they're not that effective, it takes a while for them to get out out with one
@@brooklyn560 I seen one burn down on the side of the freeway, nothing but the chassis was left
Sensible reporting. Thank you.
So environmentally friendly. That you need 40,000 gallons of water to put it out. :)
The more you look into it, the more it appears these things are absolute trash for the environment....almost like the gas guzzlers need tuning and improvements...naaaa thats insanity haha...40k gallons...isnt that like an Olympic pool?
@@pluralizor2957 I never understood why people believed these things are good for the environment look at the process of mining the lithium alone
If people really wanted to be environmentally friendly they should be buying like old 90s. Toyotas, it's better because mining and production are often more wasteful than just keeping an old car already in the system. Also 90s toyotas are honestly pretty indestructible. I'm 25 and my dad had this Corola from before I was born, the radiator finally cracked 25 years later and the repair cost like 80 dollars. Because it's so small everything is easy to fix yourself and parts are everywhere and can be reused saving materials that otherwise end up in a land fill. AC still works like an ice room.
@@konata736You’re pretty naive… But you’re only 25. It’s okay to be naive at that age! You aren’t old enough to remember the anti-asian car movement. If it wasn’t made in America, people called it “Jap Crap” and now people everywhere drive cars that are made in different Asian countries. Especially Hyundai! People hated Hyundai and now they’re competing with Germans. You also weren’t around when people said that cell phones would give you cancer and you would die five years after keeping one in your pocket. Now, everyone has a cell phone and they are not getting cancer because it’s in their pocket... When you were 2 years old, you missed the hysteria about the world coming to an end because of Y2K.
There are so many things that you missed out on. You will eventually learn that overtime that innovation is inevitable. These problems about electrical vehicle fires will eventually be solved. Someone will figure out a way to put out electrical vehicle fires effectively and efficiently
That’s just the way things are :-)
If you want to buy an older Toyota that you can work on yourself, I say go for it. Just understand that you will probably end up spending more money to maintain that car then you would spend buying a brand new smaller car with a good warranty such as a small Kia or a small Hyundai with a 100,000 mile warranty and gets over 35mpg. Good luck to you!
Well all in all if we're talking pollution then no shit regular cars are going to be worse.. thats common sense. A few fires needing alot of water is comparably better and is at least a first step
If only we could capture that explosive energy and contain it inside some kind of cylinder block...
Perhaps in liquid form, converted into vapour. Then we could add air to aid combustion.
I feel a business idea coming on friend.
@@vincentwood7036 🤣
🤣🤣
battery-powered combustion engines are the future
Hmm
In other words, don't park an EV indoors? 🤷🏽♂️
Don't park an EV anywhere near anything
Where does that toxic water go after?
Water treatment plant bigger people you fucks flush paper clogged the pipe
Probably the same place the toxic water goes after the 1000s of ice car fires. You think?
@@ptech88 True, but there is more not like about EV's. For EV charging you need a cell phone, a bank account, and a app. ICE i can use cash. EV's are cell phones on wheels. You loose all your rights like how we can't open our phones and remove the battery without damaging your phone. Or how your battery has to stay cool otherwise it damages the battery. All day your car fan will cut on until you go to drive home or etc. If the fan fails, the heat damages the battery. Batteries are expensive and will not be mass produced. Those are key things i dislike about EV.....oh and they are more harm to the planet and people digging for Cobalt with there bare hands.
@@nameuser4406 wow you really have no idea how evs work do you? You either work for ice vehicles or listen to complete morons. Either way you’re wrong
So much for reducing a carbon footprint
Just a few thoughts on this:
So are fire department's going to charge you for putting out the fire on your EV? It's costing them new equipment and materials. So your insurance rates will go up to cover the cost of an accident with your EV.
If you get in a minor fender bender with your EV, are you going to go home and park it in your home garage or shared parking? What if there's a short due to the accident and it not only causes the EV to catch on fire but burns down your house and possibly others?
Your local tax dollars fund your local fire department. Just like at airports, expensive equipment and different chemicals are needed for potential aircraft accidents and fires, so if you’re an airline passenger and unfortunately find your plane on fire due to a malfunction, you don’t have to pay the department to put the fire out. Make sense?
Do you normally get charged for any of the other equipment that the fire departments have?
Nevermind if everybody has an ev, and one fire spreads to more fire
I got a kia ev9 ad right before this video lol
Wait but lithium is an alkaly metal. Isn't water supposed to be a really bad idea?
Yep, but if you put enough water all metal will react with it and you will essentially neutralize flame from lithium.
It's not pure, metallic lithium and does not react to water the same way you think about how it went in your high school chem class.
@@zefarmer It got metallic lithium and lithium ions in it, so it very flammable when it touch the water.
@@zefarmerit doesn't need to be elemental, water causes lithium ion batteries to catch fire. The issue is there is no better solution and the water will cool the fire somewhat and a tarp with smother it.
Lithium batteries generate their own oxygen when they burn.
Surely the issue is the lithium reacting with water?
So why they using water?
To cool it down
@@AdrianFahrenheitTepes lithium reacts violently with water so surely it would heat up more
@@gabbajon5654 At this point it’s desperation because the main fire gets incredibly hot at over 2000 C or around 5,000F Usual gasoline fires only reach around 1,500 F. The frame melts into a puddle of hot lava
Switch to Sodium-ion batteries to save lives!
WOULD IT NOT BE A BETTER IDEA TO RE-DESIGN THE BATTERIES SO THEY DON'T CATCH FIRE, RATHER THAN FINDING WAYS TO EXTINGUISH EV BATTERY FIRES?????????? 🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄
no because that would mean companies make less money. and who in their right mind would want big daddy to make less money for the benefit of the planet and its people
By definition you can't. A high density battery will always be a fire and explosion risk because it's essentially a bomb. The only way to lower the risk is to lower the energy density which means the car has substantially lower range.
Lithium is an extremely reactive metal. This reactivity is what makes it attractive to battery designers and it also makes lithium very dangerous. But as usual our “leaders” turn a blind eye to the dangers.
that’s a smart idea, but y don’t ppl use dry powder &/or CO2 instead if water?
New Methods To Extinguish Electric Vehicle Fires...are needed fast!
The fires aren’t actually extinguished. All
They can hope to do is cool it enough such that some of the remaining cells that are still intact don’t go thermal and hopefully protect nearby cars and structures.
Easiest way is avoidance. Don’t buy EVs in the first place… then don’t park beside them, don’t park in a public enclosed garage.
Let it burn itself out. You can’t save them.
They can ignite other flammable stuff around them.
Don't build them, problem solved.
@@petebusch9069EVs are less likely to catch fire
An EV with a lithium ion battery pack is not a car, it's a mobile crematorium...
Oh shut up. Gas powered cars are more likely to catch on fire yet no one mentions that.
the best way to deal with the EV fire issue - do not build them
Yep
🤣🤣🤣🤣🤣🤣Why I park my EV at my neighbors house.
ECO?
What the hell are we do all of this for…
We have saved the planet🤣🤣🤣🤣🤣🤣🤣
Control of the masses...
Just curious. Do we take out the batteries once an electric car catches on fire now?
Take out like? If that was possible you might as well be able to buy a new set to switch in case of low electricity,. No they are not easily removable.
@@6teeth318 that's a shame, and sounds like they should've made it a bit more convenient.
0:38 I don't think they need the water to tell them that's a fire....
Use lithium iron phosphate battery. Problem is mostly solved... but you trade power density for reliability and safety.
Power density is what's causing the fires to be so difficult to put out in the first place. A lithium ion battery is basically a bomb. The only possible solution is moving to something with lower energy density or that's simply unreactive on its own (which then wouldn't function like a battery anymore)
That’s why there are so many BYD fires in China.
The fact that electric cars are this dangerous and allowed in the general public just goes to show you what a joke this country is.
The fact that ICE vehicles are more likely to catch fire, less environmentally friendly, less efficient, less quiet, and a whole bunch of things show why ICE vehicles are worse than EVs.
More Ev weirdness
And meanwhile the mining companies laugh all the way to the bank. Any your insurance goes up because of these EVs.
And they say ev is future. I think our future will be on fire and more emmision from such fire.
why does everyone sound so tired?
s.korea one of the hardest working nations. stephen king's long walk IRL
There is no solution.
Watertanks, rofl. For real? Lol. Not gonna happen. There will be about 1 trillion electric cars, the waterconsumption will ruin groundwater for humsns.
life without so many cars would be so much better
Ok, start by getting rid of yours first
@@user-zd5lz7su9t why do you assume that I have one.
Go back to Reddit nerd
have a point. you change, not me huh@@benlow5537
Since Roman times people have had individual transport (horses and carts). Transportation and motion are life and wealth. If you want to become immobile live in a sealed in cave.
Up the video speed to x1.5 for it to sound like normal people reporting news.
Normal to who?
the anchor looks unhappy lol
footage of lithium mining on the news every night.
you expect to decrease the damage form evs? Oh, good to know. Lol
I like gasoline
New???
so environmental friendly?
These pos are too dangerous for highway use.
Funny thing is the water can also corrode the battery cells, which creates more ignition even underwater. They probably need another material other than water to stop the fire.
sodium ion batteries are coming, problem solved.
Have a water tank under where the car sits and charges. When it goes on fire open the trap door and dunk it like a clown talking trash to you sitting on carnival booth.
kkkkk voce tem um veiculo eletrico leve um kit incendio uma capa e dois bombeiros juntos kkkkkkkkkkkkkkkk
Toxic smoke worse than fuel cars
Veículo elétrico "projeto morto"
The manufacturing of EV 60% more carbon emission than any petrol or diesel, charging takes forever, cant drive very far, lithium ion harmful toxic, extreme fire hazard. When it does catch fire, very difficult to extinguish.
The emission cost of an EV throughout its entire lifespan (from manufacturing to disposal) is minuscule compared to ICE. Of course you wouldn’t give the whole store because of your agenda.
@@SnoozeButton37 EV is as green as it's energy source. Assuming power station using clean energy. The mining of lithium ion to make the huge battery 🔋for 1 EV. Tens of thousands of times bigger than a smartphone. EV fire that can burn for days producing toxic smoke. Gallons of 💦 water wasted. Firemen drown them in river.
What’s the resale value of an EV? I think no one will buy it because of the aged batteries car? How is that environmentally friendly if it’s a one-time use thing?
And people are just hyped by these electrified cars because there are so many electrical components that can install to be flashy than your regular ICE car.
It’s 60% more carbon in manufacturing but over life time use its minuscule compared to gas vehicles. Lithium ion is toxic but it’s confined to the vehicle and only becomes toxic in the event of fires and so on.
Petrol is wide spread and is transported a lot due to the consistent use by petrol cars so the consistent transport of petrol by trucks increases the risk of a crash by the trucks which increases the risk of petrol leakage.
@@BigJMC Well, since in most big countries electricity is still being produced by a burning freaking coal...
It isn't that much better in carbon emission.
There’s a better way to shut the fire off and quickly, it’s simple by using mixed muds and sand water :)
maybe spend the effort to make better electric vehicles? Be proactive rather than reactive??
Maybe politicians and WEF should stop pushing for EVs until the battery technology is safer.
Got any new designs?
Is this the Environmentally "Friendly" vehicle?😂😂😂
It seems only good for frying the peop1e inside 🤦♀️
How does the ability to burn make it not eco friendly? Like EVs are less likely to catch fire, so...
All the engineering that went into making electric vehicles just for them to catch fire and all the engineering on how to battle these electric vehicle fires and we are willing to go through all of that, versus modernizing steam engines with propane burners AND NOT HAVING THIS PROBLEM!
omg, stop talking sense! that kind of talk can only hinder mankind's progress toward colonising mars!
Then you have grenades in every car...
@@sunrisejackdaw1779
WTF are you talking about?
So this is an international issue..
Green energy my ass
Ah, it is really so economical profitable to change from gas cars to electric since they can travel so much further, their maintence is for free, we got unlimited lithium resources so new batteries can be bought every day and our entire infrastructure is properly set up to supply every need of a EV owner from charging stations every mile to parts at every shop and this video is obiously a misinformation since EV batteries can never catch fire and they so high tech they can even produce water to cool itself.
Unlimited lithium resources? We are just opening the second lithium mine in America and they are still battling court cases to stop it from opening. Two, that is all we have, does America expect the rest of the world to supply it with lithium?
@@cg5648 It was sarcasm how nazieurope and murica want to be "eco friendly" trying to force citizens into turning to EV and reduce carbon emisions while they already struggle with supply of lithium to car factories while owners of EV need to wait couple of years for new acumulators to be available after their own broke down.
The fact that nobody recycle broken acumulators because it isn`t profitable at all make it even bigger corpo scam.
You should probably declare your comment as sarcasm because some numbskull is actually going to believe it.
@@cg5648 Sarcasm...
lesson: don't buy a electric vehicle.
another lesson: don't get a car with a sealed transmission.
Maybe BAN the danerous cars
EVs are way, way, way less likely to catch fire so I don't get the point.
Ah the growing pains of in use technology, it’s just something that’s gotta be worked out. The people who were creating tools and items for horse drawn carriages were pretty obstinate about vehicles, certain gas powered vehicle owners are gonna be like that with electric cars for a while
Except the main difference is that EVs aren't as practical as standard cars, and it's being pretty much forced on the people to buy them.
@@numatruehome100 Were they forced on the public though? Also, what is the purpose of EVs compared to perfecting the combustion engine? I'm genuinely asking these questions by the way, I'm not trying to be snarky.
@@hhasslinger9601 which, was suppose to be an incredibly apparent mission statement as literally every free nation in the world signed something called the Paris accord in a near unanimous agreement to focus on improving green technology to help preserve the planet
@@hhasslinger9601 oil is a limited resource which will eventually run out. Maybe not in our generation but our kid’s kids generation. Best to change energy source early.
Aside from that, EVs use less energy (80% efficiency) than a n ICE vehicle (Internal Combustion Engine), which has 30% efficiency.
In other words if you were to use an ICE car full tank worth of petrol to generate electricity you can charge more than 2 EVs.
If you don’t care about the environment, another incentive is that it is way cheaper to run. No more routine oil change or engine maintenance required, just brakes and tyres.
Costs about $10 to fully charge at home or $40 from a public charging station. On the road it’s quicker than a regular car.
@@hhasslinger9601 and guns weren’t as efficient or effective as bows for a while, no one would ever say that’s the case now
Hahahaah what a Joke
EV fires are worse but less likely to happen than a gas car fire. A commonly found stat is per 100,000 cars there are 25 EV fires and 1,530 gas fires.
In 2021 for every 100,000 cars on the road there were 1,000 electric powered and 99,000 gas powered. So, your stat isn't as impactful as of now
@@snakefinn This tbh. Evs are gonna continue to grow in numbers. This is currently inevitable. We need the tech that can put out lithium fires reasonably efficient before mass adoption becomes a thing.
I dunno I am pretty sure we all seen 100k cars so far and none of them caught on fire...
This especially becomes a critical issue with EV vehicles if the batteries get damaged. As fancy they are EVs sadly suck for safety reasons
Stats mean nothing these days, for all I know you just made that up, if not the place you read it made it up.
did those 1530 gas fires burn for days?
dont work waste and contamination water
Fire departments need to upgrade to put out these types of fires.
Exactly how are they supposed to do that? Do you have any idea what the sheer scale of that would entail?
The only way to actually put the battery fire out, is to cool them down, and that requires a MASSIVE amount of water... To make matters worse, the batteries are often inaccessible because they have to be in a protected part of the vehicle, to protect them from collisions.
Which makes getting to them with water very difficult, under normal circumstances, you don't want water ingress into the battery compartment.. so adding a special port to connect to water supply is not an option.. it adds way too many variables, and there's no way that could be economically feasible, to where it would actually be safe and reliable.
The workers go mad too quickly to justify the training. Unlike the olden days when people were sane. Same with soldiers. Such things are not worth the additional costs. You profit and i have to suffer-costs for your profit.? Easier to deprecate hyundai and kia and whatever you south-korea have. Either you justify for the costs or you are worthless.
There are other ways to stop EV battery fires: Don't buy an EV !!!
no need electric car ev. useless.
Electric cars are stupid idea
Noice
Stop buying them
La mia speranza è che vadano tutte a fuoco
Simple, don’t buy an electric vehicle
