TECHNICAL FIELD
[0001] The utility model relates to the technical field of fire prevention system, especially an electric vehicle parking space fire prevention system, which can automatically prevent the fire from spreading when the electric vehicle battery catches fire and automatically extinguish the electric vehicle.
BACKGROUND
[0002] Nowadays, the development of the automobile industry has shifted to the field of electric vehicle technology, and various electric vehicles have been introduced by car manufacturers for consumers to choose and use. The power of electric vehicles comes from electricity, which drives the motor to generate power. In order to maintain the endurance and high power of electric vehicles, existing technology must use lithium batteries to store electricity, and can be charged through a charging pile when the electricity is exhausted.
[0003] However, the existing lithium batteries for automobiles are composed of hundreds of battery cells connected in series and parallel. As long as one battery cell has a problem, there is a risk of fire and spontaneous combustion, such as overcharging, external short circuit, internal short circuit, or excessive temperature, which may cause lithium battery to spontaneously combust. Once the lithium battery of the electric vehicle catches fire, a thermal runaway will occur inside the metal vehicle shell, with a continuously increasing temperature, and as long as there is oxygen around, the fire will continue to burn. The existing fire extinguishers are difficult to spray fire extinguishing agents into the lithium battery protected by the vehicle shell, and must wait until all the thermal runaway reactions are completed before the fire is completely extinguished. However, allowing the burning electric vehicle to continue to burn may spread to other vehicles or cause a fire in the parking lot.
[0004] Therefore, how to automatically detect the fire and control the fire of the electric vehicle even automatically extinguish the fire to prevent the fire from spreading to other vehicles or buildings nearby when the electric vehicle is parked in the parking space and the battery spontaneously combusts is a problem that the utility model wants to overcome.
