Frank, here is a statement from the National Highway Traffic Safety Board

"In August 2012, the National Highway Traffic Safety Administration
(NHTSA) decided to begin a US$8.75 million study of whether
lithium-ion batteries in plug-electric vehicles pose a potential fire
hazard. The research looked at whether the high-voltage batteries can
cause fires when they are being charged and when the vehicles are
involved in an accident.[23] The research from 2013 was initiated to
evaluate the fire risk 400-volt lithium ion batteries pose. General
Motors assisted the NHTSA researchers, and the study was issued in
October 2017. The report concluded, "...ignition of flammable
electrolytic solvents used in Li-ion battery systems are anticipated
to be somewhat comparable to or perhaps slightly less than those for
gasoline or diesel vehicular fuels. The overall consequences for
Li-ion batteries are expected to be less because of the much smaller
amounts of flammable solvent released and burning in a catastrophic failure situation."

This entire subject started when I attempted to warn you that EV's
are unsafe to an extent that you're not aware of. But you violently
denied that with all of the BS you could muster.

Right there it says that EV fires are about as often as gasoline
fires on ICE vehicles. That means RARE but ICE cars do not have
gasoline explosions and are almost always caused by wrecks whereas EV
explosions occur for little to no reason and are so violent that you
cannot exit to safety in most cases.

I realize that you believe that buying an EV proves your God-like
judgement but if I were you I would put very many very loud fire
detectors around your home. And keep their batteries up to date.

"Australia?s Department of Defence funded EV FireSafe to look into the
question. It found there was a 0.0012% chance of a passenger electric
vehicle battery catching fire, compared with a 0.1% chance for internal
combustion engine cars. (The Home Office said it was unable to provide
data for the UK.)

Elon Musk?s Tesla is the world?s biggest maker of electric cars. It says
the number of fires on US roads involving Teslas from 2012 to 2021 was
11 times lower per mile than the figure for all cars, the vast majority
of which have petrol or diesel engines."

Frank claims there to be 12 million EV's on the road and using the
Australian numbers that would put the number of EV fires at 14,000.
Frank claims that there were only 12 fires.

Who could disagree with that? But if your ICE car is sitting in your
garage it is safe. If an EV is in the garage just sitting there it is
NOT. Elon has made them about a safe as possible for Lithium ion battery
but other companies do not have his experience and are only copying Tesla
without knowing why. This means that they make errors. Ford has hundreds
of engineers that can be assigned each and every stage of safety, it is
rare for EV manufacturers to have even a dozen. Should we be surprised if
they are simply not reliable?

 Tesla as with others buy batteries or licensed from others in Tesla case
Panasonic since 2009. Nothing special about their batteries, indeed they
chose 18650 types as they are ubiquitous than having to be special packs as
some other makers had used.
 As far as I’m aware batteries with one exception (Nissan Leaf) have
massively outlasted doom laden expectations and have improved by some
margin over the last decade or more.
 The idea of using old car batteries for X products has rather fell short
due to lack of supply ie the batteries are still largely in the cars.
 Yes absolutely software can help with battery management and usage, and
ignore damaged cells. But if not all cars I’d assume use protected
batteries ie have a circuit to prevent damage and potentially fires. Ie
it’s a physical component than relying on software.
 As ever battery fires are overwhelming stuff that is cheap and poorly made,
some of the early led bike lights the battery packs where very iffy and
advice was to charge in your garage not your home and so on, as these where
not consumer ready/quality, probably turn of the century I’d guess?
