Description

System and Method of Electromagnetic Vehicle Fire Suppression in Mechanical Parking Station Embodiments of the present invention relate to a fire extinguishing system and method for an electric vehicle in a mechanical parking lot, and more specifically, to a fire extinguishing system and method for an electric vehicle in a mechanical parking lot that immediately extinguishes a fire that has occurred in the electric vehicle in the mechanical parking lot. Recently, the adoption of electric vehicles has been steadily expanding. Due to the characteristics of electric vehicles, the spread of a fire in a vehicle is very rapid, taking only 5 to 10 minutes, which makes it difficult for fire trucks to respond immediately to the scene. The main cause of electric vehicle fires is the battery located in the vehicle's undercarriage. When a fire occurs, it spreads to the surrounding area within a short period of time, and the flames, reaching temperatures of nearly 1400 degrees, cause significant damage to underground parking structures such as floors, beams, and pillars, raising concerns about building collapse. If an electric vehicle catches fire, a rapid response is required for initial fire suppression; however, since there are limitations to extinguishing the fire once it has already progressed, it is necessary to quickly identify abnormal signs before it develops into a fire. In particular, mechanical parking garages are conventional elevator-type parking systems equipped with independent dedicated parking spaces in building and tower configurations, allowing multiple vehicles to be parked in a limited space; as a result, they are continuously being installed, primarily in areas with high parking demand. In this case, the parking tower facilitates the entry and exit of vehicles by using a method where, once a vehicle stops at a single entrance, it is transported to a parking space via a separate device. However, when a fire breaks out in a vehicle inside a parking tower, it cannot be extinguished and easily spreads to surrounding vehicles, causing significant damage. In particular, electric vehicles, which have been increasing recently, have a problem in that they cannot extinguish fires in electric vehicles with fire extinguishing equipment installed in narrow parking towers, as fires cannot be suppressed by simply spraying fire extinguishing liquid when the fire spreads to the battery and they must be moved to an open area for separate firefighting operations.
