Description

Electric Vehicle Fire Disaster Prevention Structure

The present invention relates to an electric vehicle fire disaster prevention structure, and more particularly, to an electric vehicle fire disaster prevention structure capable of preventing damage to the surroundings due to an explosion when a fire occurs in an electric vehicle and enabling rapid fire extinguishing work.

In general, with the number of registered electric vehicles reaching about 140,000 in Korea, fires are frequent and fatal accidents occur, so it is pointed out that safety measures are urgently needed.

As the automobile industry declared this year as the first year of popularization of electric vehicles, concerns about safety are growing. This is because there is no clear way to solve the immediate problems such as fire accidents of unknown causes and difficulties in suppression and rescue.

Electrical factors were the most common cause of ignition (58.0%). It is presumed to be caused by batteries and related parts or electric shock. 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, a driving storage battery that stores a very high capacity energy is placed on the bottom of the vehicle. Fire suppression is difficult due to the re-ignition phenomenon caused by continuous heat transfer.

Therefore, effective fire suppression of electric vehicles depends on the temperature drop of the entire drive storage battery, so fires are extinguished by spraying a huge amount of water or putting the vehicle into a tank. However, this method takes a lot of time or is difficult to respond to in the field.
