Description

Movable fire extinguishing parking lot for electric vehicles {MOVABLE FIRE EXTINGUISHING PARKING STATION FOR ELECTRIC VEHICLE}

The present invention relates to a mobile fire extinguishing parking lot for an electric vehicle, and more particularly, when a fire occurs in an electric vehicle due to battery failure, battery shock, and overcharging, the electric vehicle is isolated and extinguished at the same time to prevent the fire from spreading. It relates to a mobile fire extinguishing parking lot for electric vehicles that can be immersed in water to quickly extinguish a fire.

In general, in a situation where the number of electric vehicles registered in Korea reaches about 140,000, it is pointed out that safety measures are urgently needed due to frequent fires and even fatal accidents.

With the automobile industry declaring this year as the first year for the popularization of electric vehicles, concerns about safety are growing. This is because there is no sharp way to solve the immediate problems such as successive fire accidents of unknown cause and difficulties in suppression and rescue.

As for the ignition factor, the electrical factor was the most common at 58.0%. It is presumed to be caused by batteries and related parts, electric shock and overcharging. The cause was unknown in 14.5% of cases. In addition, there were mechanical factors (14.5%), traffic accidents (7.0%), and carelessness (3.0%).

In electric vehicles, drive storage batteries that store energy with a very high capacity are placed on the bottom of the vehicle. Due to this, it is difficult to extinguish the fire due to the re-ignition phenomenon caused by the continuous heat transfer.

Therefore, since effective fire suppression of an electric vehicle lies in the temperature drop of the entire driving battery, fire suppression is carried out in the form of spraying a huge amount of water or putting the vehicle in a water tank. However, this method takes a lot of time or is difficult to respond to in the field.
