Description

[0001] A FIRE EXTINGUISHING SYSTEM IN CHARGING STATIONS

[0002] Technical Field

[0003] The present invention relates to a fire extinguishing (suppression) system for injecting a fire extinguishing material directly onto a battery by detecting a fire that occurs while charging and / or holding an electric vehicle being located in a charging station.

[0004] Background of the Invention

[0005] Fire occurrence on an electric vehicle while charging the electric vehicle is one of the most frequent problems today. Due to the fact that no one is present at the location where the electric vehicle is located during the charging process, the occurrence of fire cannot be detected instantaneously. Therefore, a fire occurring on an electric vehicle cannot be responded instantly and this causes material and non-material damages. Today, it is ensured to detect the emerging fires by means of thermal cameras placed at the location of the charging station. It is provided by means of a fire extinguishing device, which consists of a storage tank and nozzles placed in the charging station, to spray the water stored on a detected fire. However, even if a fire occurrence is detected in the said systems, the fire cannot be taken under control in a short time due to the inability to directly respond to the fire on the battery.

[0006] Therefore, it is understood that there is a need for a system for detecting a fire by means of sensors placed on a charging station and injecting a fire extinguishing material directly onto the battery of an electric vehicle by means of a fire response element placed on the floor in such a way that it will correspond to the bottom of the electric vehicles in the charging station in the state of the art. The Chinese patent document no. CN215876040, an application included in the state of the art, discloses a fire extinguishing system for an electric vehicle charging station. The invention subject to the said patent Chinese document relates to a fire extinguishing system for an electric vehicle charging station. The fire extinguishing system comprises a fire monitoring device, a fire extinguishing device, a vehicle isolation device and a control unit; the fire monitoring device adopts thermal imaging cameras and it is installed on a keel of a charging station awning through a camera support, each parking space is correspondingly provided with one thermal imaging camera, and a lens of each thermal imaging camera is aligned with a parking area of the corresponding parking space. The fire extinguishing device comprises a water storage tank and fire-fighting nozzles, a group of fire-fighting nozzles are arranged above each parking space, the fire-fighting nozzles are mounted at the top in the awning through nozzle brackets, and the water spraying direction points to the parking area of the corresponding parking space; the firefighting sprayers are connected with the water storage tank through water conveying pipes; the vehicle isolation device adopts electric reels, a group of electric reels are arranged above a boundary of every two adjacent parking spaces, and the electric reels are suspended and mounted at the top of the awning to be lowered; fireproof cloth is wound on the electric reel; the control unit is installed in a charging station distribution box.
