More on battery hazards

mapj1

As we have recently been discussing the new PAS for solar/battery type systems, and a lack of know how with DC, elsewhere on this forum

I thought that folk who have the patience, and can tolerate the ads for the tall buildings conference, may find this talk, on the safety or otherwise of battery systems, informative, Some more up to date facts and figures and some spectacular videos of things going wrong.

Certainly sobering stuff.

  • There are various kinds of Lithium chemistry batteries ... with different risk profiles.

    Not all are as vulnerable to impact, puncture, or external temperatures .. but issues can still happen.

    With some lithium battery chemistries, electrical- and temperature- related risks of the battery itself being a source of fire or explosion can be addressed by an appropriate, fail-safe, battery management system.

    All batteries of any chemistry store energy, and if for any reason that energy is released quickly, say for example the battery is a victim of fire, rather than the cause, the results can be very nasty. It's also highly probable that smoke and fumes from a battery that is a victim of fire, are going to be hazardous, regardless of whether the particular chemistry might evolve explosive or harmful gases or vapours during faults or normal operation.
