Fire extinguishing device, fire extinguishing method, controller and computer readable storage medium

Abstract

The invention relates to a fire extinguishing device, a fire extinguishing method, a controller and a computer readable storage medium, a smoke sensor and a temperature sensor are arranged in an electrical area of a prefabricated cabin energy storage system of a battery, the smoke sensor and the temperature sensor are both connected with the controller, and collected smoke sensor and temperature sensor signals are sent to the controller; the fire trace tube is used for extending into a battery area of a prefabricated cabin energy storage system of a battery; the controller is used for judging whether an electrical area of the prefabricated cabin energy storage system of the battery is on fire or not according to the received smoke sensing and temperature sensing signals, and if yes, heptafluoropropane is adopted for extinguishing fire; and judging whether the battery area of the prefabricated cabin energy storage system of the battery is on fire according to the pressure of the fire trace tube, and if so, breaking the fire trace tube and extinguishing fire. According to the invention, the fire detection tube extends into the battery cabinet, so that the front-end detection is high in interference resistance and cannot receive external electromagnetic interference; the fire extinguishing device can effectively and quickly extinguish open fire of the battery through a fire extinguishing agent.

Description

technical field [0001] The invention belongs to the technical field of battery fire extinguishing, and in particular relates to a fire extinguishing device, a fire extinguishing method, a controller and a computer-readable storage medium. Background technique [0002] Lithium-ion batteries have the advantages of large specific capacity, high working voltage, long cycle life, small size, light weight, etc., and they have been used more and more as high-energy power sources. However, the heat generated by the lithium battery can easily cause safety hazards, especially when the battery is charged and discharged with a high current, it can easily cause the battery to explode, thereby causing harm to personal safety and the environment. In addition, the internal heat of a battery module composed of multiple batteries is higher, and after a single battery fails, if it explodes or burns in an abnormal situation, how to quickly extinguish the flame, reduce the impact on other batter...

AI Technical Summary

Problems solved by technology

[0005] The existing fire extinguishing device does not distinguish the fire of the energy storage system in detail, which makes the fire extinguishing efficiency low, and the phenomenon of re-ignition may occur after the battery fire is extinguished
