[0001] A SYSTEM FOR EXTINGUISHING FIRE IN ELECTRIC VEHICLES

[0002] Technical Field

[0003] The present invention relates to a system for automatically ejecting a hose from inside an electric vehicle, which establishes a physical connection between the battery environment and the external environment and makes the ejected hose ready for use by automatically inflating it during a fire in order to enable direct intervention to a fire occurring in the battery of the electric vehicle.

[0004] Background of the Invention

[0005] Fire may occur in the batteries of electric vehicles during charging and / or as a result of an accident. In the event of a fire in the cells of the lithium batteries used in the said electric vehicle, a chemical reaction that produces oxygen (02) takes place. The oxygen formed by the chemical reaction on the battery cannot be extinguished with carbon dioxide (C02) based extinguishers. In various personal electric vehicles that are distinguished by body type, for example, hatchback, sedan, and SUV, it is very difficult for fire brigades to reach the battery in case of a possible fire since the batteries are placed at underneath the vehicle. In addition, the fact that the battery is produced in a way that is resistant to outdoor conditions makes it impossible for fire brigades to intervene with the battery in case of a possible fire due to its design. In the event of a possible fire on the electric vehicle, it takes a very long time for fire brigades to bring the fire under control due to the placement of the battery underneath, the fact that the battery is designed in a way that will not be affected by external conditions and the chemical reactions that take place on the battery. The reaction and trapped gas formed on the battery due to the fire that cannot be brought under control in a short time causes an explosion on the vehicle. An explosion causes the fire on the vehicle and shrapnel fragments from the vehicle to spread around, causing loss of life and property. For the explained reasons, it is very important to bring a fire on an electric vehicle under control in a short time.

[0006] For this reason, there is a need for a fire hose which establishes a direct physical connection between the battery and the external environment in order to enable the fire brigades to intervene in a fire on the electric vehicle from a safe distance, and a system which enables the fire brigades to intervene in the fire by transferring the fire extinguishing liquid directly from the external environment to the battery by establishing the physical connection unidirectionally.

The control unit (10) operates the compressed air tank (8) by triggering the valve (9) located at the free end of the hose (7) that is ejected by the rotation of the reel (5) around itself and enables the hose (7) to be inflated automatically.

[0034] Industrial Application of the Invention

[0035] The electric vehicle (2) included in the inventive system (1) is any vehicle that is operated by using the energy stored on the battery (3). With the help of a sensor (3) located on the electric vehicle (2), accidents and fire situations occurring on the electric vehicle (2) are detected and the relevant data are transmitted to the control unit (10). The reel (5) has a structure that can rotate around itself in the position where it is mounted on the electric vehicle (2) and holds the hose (7) wrapped thereon. The reel (5) has a spring structure which is previously compressed and fixed with the help of a relay (5.1). The mounting of the reel (5) with the electric vehicle (2) is carried out with a swivel joint adapter and the swivel joint adapter is connected to the transmission pipe (6) at the other end. The transmission pipe (6) enables the fire extinguishing liquid transmitted from the external environment through the hose (7) to be directly transferred to the battery (3) by being located between the battery (3) and the reel (5). The hose (7) is held wrapped around the reel (5) by being connected at one end so as to be fixed on the reel (5). At the free end of the hose (7), where there is no connection, there is a compressed air tank (8). The compressed air tank (8) is triggered during an accident and / or fire and makes the hose (7) ready for use by inflating it. There is a valve (9) located between compressed air tank (8) and hose (7) and it enables the compressed air tank (8) to be triggered. The control unit (10) triggers the relay (5.1) located on the reel (5) by detecting the accident and / or fire in line with the data received from the sensor (3) and enables the reel (5), which was previously held in a fixed position by compressing the relay (5.1) releases, to rotate around itself. The reel (5) ejects the hose (7) wrapped thereon by rotating around itself. The control unit (10) triggers the valve (9) located at the end of the hose (7) ejected outwards and enables the hose (7) to be inflated by operating the compressed air tank (8). The fire extinguishing liquid is enabled to be sent directly on the battery (3) from the external environment by using the physical connection formed through the hose (7) and the transmission pipe (6) by dismantling the valve (9) located at the end of the hose (7) inflated by being ejected into the external environment and the compressed air tank (8) by the fire brigade teams.
