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).

Isn’t safety suppose to be first? Imagine the fires inside tunnels and parking garage. Yikes!

In other words, don't park an EV indoors? 🤷🏽‍♂️

Just curious. Do we take out the batteries once an electric car catches on fire now?

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?

New Methods To Extinguish Electric Vehicle Fires...are needed fast!

If only we could capture that explosive energy and contain it inside some kind of cylinder block...

that’s a smart idea, but y don’t ppl use dry powder &/or CO2 instead if water?

Wait but lithium is an alkaly metal. Isn't water supposed to be a really bad idea?

Surely the issue is the lithium reacting with water?
So why they using water?

So environmentally friendly. That you need 40, 000 gallons of water to put it out. :)

Switch to Sodium-ion batteries to save lives!

🤣🤣🤣🤣🤣🤣Why I park my EV at my neighbors house.

Use lithium iron phosphate battery. Problem is mostly solved... but you trade power density for reliability and safety.

0:38 I don't think they need the water to tell them that's a fire....
