Abstract

The invention discloses a fire early warning and fire extinguishing control device and a method applied to a battery box or a supercapacitor box. The device comprises a control module and a detecting module; the detecting module includes at least one sensor for acquiring environmental data in the battery box or the supercapacitor box; the output of the sensor is connected to the input of the control module; the control module detects faults of the detecting module; when the faults are detected, the corresponding sensor is closed and / or an alarm instruction is output; and the control module processes the received data to output the alarm instruction and / or start a fire extinguishing signal according to disaster information. The device can prevent the protection failure of the battery box or the supercapacitor box caused by the faults of the sensor.

Description

technical field [0001] The invention relates to a fire early warning device, in particular to a fire early warning and fire extinguishing control device and method applied to a battery box or a supercapacitor box. Background technique [0002] New energy vehicles are one of the seven strategic emerging industries in my country, and their power sources are lithium-ion batteries or supercapacitors. Among them, the safety and reliability of lithium-ion batteries and supercapacitors are particularly critical. When a short circuit, thermal runaway, high temperature, external force extrusion, puncture, etc. occur inside a lithium-ion battery or supercapacitor, it is easy to cause thermal expansion of the battery or capacitor, resulting in explosion and combustion. For this reason, many devices for battery box alarm and fire extinguishing have appeared in the prior art, including a number of sensors and control modules used to detect the internal environment data of the battery box...
