2차 발화 잦은 전기차 화재 소화포•충전소 수조로 진화
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.
