What parameters do we need to predict & detect imminent danger caused by a charging battery?

HKPhysicist

Dear Engineers,

Every month or year, charging batteries cost human lives and total household destruction.

I have successfully developed a Flame Detector which sends alert to internet broker over a wifi router once it detects "flame" near a charging battery.

Then, I want to improve it and add some more parameters to predict & detect imminent danger caused by a charging battery.

What suggestions could you make to improve my flame detector design?  Thanks for your comments.  Upside down

    assuming indirect observation, using sensors.
    The camera based flame detection is one of the oldest sensor technologies in existence. Though most of the technologies are proprietary.
    by the time a battery is on fire, the problem is too severe.  if you have a confined space, where you could monitor gases present, you could develop a baseline, and monitor changes, which should tell you if a hazard is emerging, before an actual emergency emerges.

    If only there was a way to detect issues with a battery before changing ... oh wait, there is, and they are integrated into many items.

    I don't mean to dissuade you, it is indeed a problem that needs more advancements.
    what if you could evacuate all the air from the storage container upon issue detection?
    If you store a battery between 2 insulated metal plates, and monitor the system capacitance, perhaps you could figure out safe charging, discharging, and unsafe changing conditions, by captive load curves.

    Pumping out all the air or replacing with some inert gas is completely pointless, lithium battery fires do not need any oxygen to burn, they generate it themselves.
