Intelligent fire extinguishing system for battery box

Abstract

The battery box intelligent fire extinguishing system comprises an information obtaining module, a control module and a driving module, the information obtaining module is electrically connected with the control module, and the control module is electrically connected with the driving module; wherein the information acquisition module is a composite detector, the composite detector comprises a first detector and a second detector, and the first detector and the second detector are both electrically connected with the fire alarm controller; the first detector is used for acquiring a smoke concentration signal and uploading the real-time smoke concentration signal to the control module, and the smoke concentration signal is acquired by detecting the concentration value of CO in the air through the first detector; the problems that in the prior art, a fire extinguishing system of a battery box cannot accurately judge fire disasters, and report and missing report phenomena are caused are solved; meanwhile, the fire extinguishing system is high in maintenance cost and not suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing devices, in particular to an intelligent fire extinguishing system for a battery box. Background technique [0002] When the lithium battery in the battery box is subjected to external heating, overcharge, overdischarge, high current charging, puncture, extrusion and external short circuit, it will cause internal short circuit and electrolyte leakage, thereby causing internal electrode-electrolyte reaction, decomposition reaction and external short circuit. The electrochemical reaction causes the heat generated inside the battery to be greater than the heat released, resulting in a sharp rise in the internal pressure and temperature of the battery, and the battery pressure relief valve pops open, releasing combustible gas, smoke, and combustion and explosion. Existing circuit breakers, fuses, battery management systems, etc. cannot prevent the reaction of lithium ions inside the battery...

AI Technical Summary

Problems solved by technology

[0003] Based on the above situation, it is necessary to provide an intelligent fire extinguishing system for the battery box. The fire extinguishing system of the battery box in the prior art cannot accurately determine the fire, resulting in the phenomenon of reporting and missing reports; at the same time, the maintenance cost of the fire extinguishing system is high, and it is not suitable for large-scale promotion.
