The tab of member is corresponding with two output terminals conductive connected, is additionally provided on cover board body and injects electrolyte into battery case inner cavity
Liquid injection hole.
At this stage for the monitoring of the fire behavior of battery and battery system and fire-fighting technique, mostly as Authorization Notice No. is
Shown in the utility model patent of CN205964755U, the fire extinguishing system of use includes the monitoring to battery fire behavior state parameter, packet
It includes the temperature to battery, voltage, gas, salt fog, light etc. to detect, battery fire alarm is then established by relevant algorithm
Model theoretically monitors the fire behavior state of simultaneously early warning battery.But under actual conditions, the extinguishing device of battery system is very multiple
Miscellaneous, reliability, durability and service life are difficult to be consistent with battery system.The detector of battery key parameter uses the longevity
Life is well below battery.And there is the case where failing to report and reporting by mistake in battery system operational process.To temperature, electricity
The reliability of the detection mode of pressure, gas, salt fog, light etc. is unable to get solution, and it is accurate really to carry out to battery fire residence
Early warning.In the prior art, the mounting means of battery extinguishing device, fire-fighting mode will affect the sealing protection grade of Battery case,
Under extreme weather (storm water) and extreme operating condition, the safety of battery system is seriously affected.And existing battery fire extinguishing
Device is difficult in maintenance, and maintenance cost is high, and all uses high-pressure bottle substantially, and maintenance is dangerous.
