Description

Fire suppression devices for electric vehicles

[0001] The present invention relates to a fire suppression device for an electric vehicle, and more particularly, to a fire suppression device for an electric vehicle that can quickly extinguish a fire in the electric vehicle itself in a short period of time and prevent the fire from spreading when a fire breaks out in the electric vehicle, and can also easily install the fire suppression device with a simpler structure, thereby significantly reducing installation costs and time, and can solve the problem of taking up a lot of installation space by being able to be installed in an existing parking area.

[0002] Electric vehicles (EVs) are vehicles that use electric motors instead of internal combustion engines to generate power. Most use lithium-ion batteries to store energy. These EVs use charging equipment (chargers) located at charging stations or parking lots to recharge their batteries. However, the charging process can cause fires due to battery overheating, electrical shock, overcharging, internal short circuits, and poor contact.

[0003] Currently, many electric vehicle parking lots or charging stations do not have dedicated fire extinguishing devices installed to extinguish fires in electric vehicles. Therefore, there is no direct countermeasure against electric vehicle fires. In addition to the charging vehicle being completely burned, the fire can spread to surrounding vehicles, parking lots, and charging facilities, causing damage to life and property. Therefore, it is urgent to establish safety measures to address this. Therefore, various technologies are being developed to extinguish electric vehicle fires.

[0004] For example, Korean Patent Publication No. 10-2022-0130440 (Electric Vehicle Fire Suppression Device) (published on September 27, 2022) and Korean Patent Publication No. 10-2023-0123542 (Fire Suppression Tank for Electric Vehicle Charging Station) (published on August 24, 2023) disclose a technology for stabilizing the battery and extinguishing the fire by filling water in a tank provided around an electric vehicle in the event of a fire in the electric vehicle, and Korean Patent Registration No. 10-2491008 (Electric Vehicle Fire Suppression Device) (announced on January 27, 2023) disclose a technology for extinguishing the fire by blocking oxygen using a fire extinguishing cloth covering an electric vehicle in the event of a fire in the electric vehicle.

[0005] However, conventional fire suppression devices for electric vehicles have the problem that they require a lot of installation cost and lack installation space, and in addition, it is difficult to quickly extinguish the fire in the early stages of an electric vehicle fire and prevent the fire from spreading to the surrounding area.

[0006] In other words, the existing fire suppression devices using water tanks or fire extinguishing foams require additional construction of existing parking lots because water tanks or fire extinguishing foams must be installed around the vehicles, which not only increases installation costs but also takes up more installation space than the original parking area. In addition, the existing fire suppression devices using water tanks or fire extinguishing foams have the problem that when an electric vehicle fire is caused by a problem such as a battery, thermal runaway occurs rapidly, but it is difficult to extinguish the fire early because a partition wall and water tank must be installed and then the interior must be filled with water again, and this causes the fire to spread to surrounding vehicles, parking lots, and charging facilities.

[0007] Therefore, in the event of a fire in an electric vehicle, a fire suppression device for an electric vehicle is required that can not only quickly extinguish the fire in the electric vehicle itself and prevent the fire from spreading, but also easily install the fire suppression device with a simpler structure, thereby significantly reducing installation costs and time, and can be installed in existing parking areas, thereby solving the problem of taking up a lot of installation space.

[0008] The present invention has been invented to improve the above-mentioned problems, and the problem to be solved by the present invention is to provide a fire suppression device for an electric vehicle, which comprises a plurality of fire suppression nozzles that spray extinguishing fluid in a direction toward an electric vehicle when a fire breaks out while the electric vehicle is being charged, and a plurality of water wall forming nozzles that spray a blocking fluid to form a water wall surrounding the front, rear, and left and right sides of the electric vehicle, and is configured to move or simply install the entire fire suppression device to a parking area, so that when a fire breaks out in the electric vehicle, the fire in the electric vehicle itself can be quickly extinguished in a short period of time, and the phenomenon of the fire spreading to the surrounding parking area such as surrounding vehicles, a parking lot, and an electric vehicle charging facility can be prevented, and in addition, it can be installed as is in an existing narrow parking area without taking up additional space due to a simpler structure, and can be easily installed without additional construction work on the existing parking area, thereby significantly reducing the installation cost and time of the fire suppression device.
