Description

Automatic safety monitoring system for electric vehicle charging stations and operating method thereof The present invention relates to an automatic safety system for an electric vehicle charging station and a method of operation thereof, and more specifically, to an automatic safety system for an electric vehicle charging station and a method of operation thereof that automatically responds to accidents that may occur indoors or outdoors where an electric vehicle charger is installed. As the adoption of electric vehicles (EVs) expands, electric charging infrastructure is also growing rapidly. In particular, as the installation of charging stations in enclosed spaces, such as indoor and underground parking lots, increases, the risk of safety accidents associated with this is also on the rise. Typical safety accidents occurring during EV charging include electric shock and fire; notably, fires caused by battery ignition require special caution, as they are difficult to extinguish and can result in significant damage, unlike typical vehicle fires. According to statistics from the Korea Transportation Safety Authority, fire accidents involving electric vehicles are showing an increasing trend every year, with a particularly high proportion of accidents occurring during charging. This is due to the existence of various risk factors during the charging process, such as overcurrent, overheating, and short circuits. Furthermore, charging in enclosed spaces makes rapid evacuation and firefighting difficult in the event of a fire. Safety equipment in conventional electric vehicle (EV) charging stations primarily relies on flame and smoke detection sensors. However, these sensors have limitations, such as the fact that they can only detect a fire or dangerous situation after a certain amount of time has elapsed since its occurrence, and that they fail to prevent additional casualties in dangerous situations because they cannot recognize people or human movement. Furthermore, conventional sprinkler systems that activate upon the occurrence of a fire in EV charging stations suffer from the problem that they are ineffective in preventing the spread of fire due to the specific characteristics of EV battery fires.
