The new, unusual solution to EV fires: High-speed battery ejection
New technology has been demonstrated in China that sees an electric vehicle's battery rapidly ejected to keep occupants safe from an imminent fire.
...My first thought was, surely this is a joke. But if it is a joke, someone has gone to a lot of trouble to make it look real.
At an event earlier this month, new technology was demonstrated on Chery's iCar 03 that can see a vehicle's high-voltage battery ejected 3-6 metres away within a second of thermal runaway being detected.
It's ejected from the vehicle using a gas generator, much in the same way as an airbag works, with the idea to get the battery away from vehicle occupants before it catches fire.
In the demonstration video, shared across Chinese media including cnBeta, the battery is ejected with a bang into a nearby pit and then quickly shrouded.
However, there are naturally concerns over the high-speed ejection of a battery weighing potentially several hundred kilograms.
MGUY has responded in his usual measured way to this latest EV safety innovation.
A burning EV battery is essentially a thermite bomb. Adding a gas catapult to the thermite bomb turns the vehicle battery into a short range thermite bomb launcher.
Would this EV innovation be legal in countries which restrict gun ownership? Imagine if Europe's violent street gangs got their hands on such weapons.
To be fair the explosive battery ejector system likely does improve safety for the vehicle occupants. Probably not so much for any unlucky pedestrians walking past when the ejection system is triggered.
I'm kind of lost for words on this latest EV innovation. I mean I once thought of publishing this idea on WUWT as an April fools joke, but I decided not to, because I thought the idea was too stupid to trick anyone.

That is called "potential energy" sort of "out of control" are something that could cause a real disaster of epic proportions - cause really - you can't use water on those fires - water only feeds the energy!
And if you swap it for entitlement. The things I see almost daily, make a lot more sense.
Because at the end of the day, if you can afford this car. Your entitled to be safe. At others expense.
that thing should never got off the drawing somebody should have straight through the common sense card down but here we are
I mean - do you remember the fires that have happened in parking lots when EV's get going - that is not an easy fire to put out.....speaks to engineering flaws - and flipping the flaw out is ridiculous being God knows to whom the flaw causes harm - if it was the forest then the whole damn town could burn down - not to mention all the electronics on those vehicles and the "switches" they like are equipped with...tis a fools game and who needs all the damn complexity with batteries only made by moving tons of earth literally and vehicles "too smart" for their own good.
Not to mention damn batteries wear down over time - have to be replaced every 8 years or so - and that don't come cheap.
I don't think their practical if you enjoy long trips on a whim.
And who doesn't?
And not practical for me in my career and daily lifestyle.
➣bulletproof backpacks for scholars, since the shootings are so f*cking normal.
➣Building houses with plastic bottles fulfilled with garbage... instead of stopping garbage (specially plastic) production.
➣Flesh grown in a lab with cancer genes to stop livestock breeding, since its farts are damaging the planet.
➣Vaginal protheses with teeth, to injury violators. No joke, this happened in Africa.
➣Drinking straws in nightclubs, that colorize the beverage if a dangerous additive has been put, to protect women from predators.

So, instead of producing batteries that don't spontaneously burn or allowing hydrogen or even water engines:
"Look, we developed an ejection system for burning batteries".
We live in a f madhouse.
now your talking
Madhouse is correct answer. With a few choice expletives added.
from Ohio. Around 40 years ago

I got an idea about "battery banks" but it calls for better battery ideas!
Oh, yeah, and they don't burn, explode or melt down.
Prototypes are already fine tuned and CATL predicts mass production by years end.
Lately I'm sort of invested in "silver" and lately the price of silver has been on the rise being it is the most reflective I reckon - from the ai: Maybe tis time to invest in better battery ideas.
Oh and I should add silver is also most conductive - or is it?
Well one thing it is being all the damn silver came out of Cerro Rico or some such out of Bolivia - silver is abundant nowadays - ain't it?
I mean run the mercantile numbers - Spain and the conquistadors came to what is called Bolivia now and they found the mountain of silver and forced slave labor to mine the metal most reflective and conductive I reckon - but in hindsight how the hell did that work out for Spain mercantile-wise?
Regardless, the silver was removed from Cerro Rico upon the broken backs of the workers and Spain was rich mercantile-wise till the price of silver collapsed - you know - supply and demand economics 101 - and now here we are with bitcoin - a mathematical construct - and narratives of lies aplomb as the Charlie Kirk's of the world get assassinated one after another.
Sad world we live in ain't it?
Eff em all - I'm an anarchist - Kropotkin style.
I've read that silver is the most sought after precious metal in India.
Paul Stramer, Lincoln County Watch, is always touting it's value and has organised sales with a mint. 60oz minimum order. Currently $US44 an oz. Is that good? Not available to me as I'm in Australia. Given our rubbish exchange rate, that'd be near double.

You got "electrical conductivity and thermal conductivity" and according to this article silver is TOP.
[Link]
And the ai seems to state silver is also the most electrically conductive - tis speculated it is due to that one "free roaming" electron.....so there must be something to electrons and protons - as for neutrons - I think they are glorified "fudge factors". From the "ai": As for purchasing silver - maybe you could find somebody in Australia who has some for sale?
Peace!

The Aussie dollar keeps on hovering around that 65 cent mark, it got to just over 66 cents briefly a few weeks ago. Briefly is the operative word. Hasn't come back up since.
I remember when we were 76 cents, that was bad compared to the 80+ we'd had for a long time. Who'd have thought that they'd think that was bad back then, when it's so good compared to the last several years?
And it bugs me that one Australian site charges more than a 10% premium upon spot.....but lately both gold and silver have been trending up.....and I put forth they were "held in detention" by paper products - so remember this if you are going to spend funds - "physical" is best!
Peace!

ps - currency exchanges in my humble view are also "rigged" - and this is why some like Buffet speculate that the "derivative instruments" are equivalent to "nuclear weapons" - cause if they get tripped - get ready for some turbulence and that is the "gentle" word for it.....it will be when the knives come out - cause lots of folks love their mammon more than humanity.......that is why sometimes "in the hand" is the best sort of insurance if you know what I mean!
Happy hunting and remember "fiat" is just paper - it burns...but precious metals have always been considered of value.

my only fear. And it's very real. Especially looking around at the state of things. From wiki:
"Yes, the U.S. government holds broad emergency powers, and Congress can, under a declared national emergency or war, authorize the president to regulate gold and silver, which could include seizing private holdings, though this is now seen as highly unlikely given the dollar is a fiat currency and the economic rationale for confiscation is gone. While the 1933 Executive Order 6102, which mandated gold confiscation, was repealed in 1974, the legal framework for such actions remains a theoretical possibility during extreme circumstances."
Only part of this I know for a fact wiki is lying about. Is the highly unlikely sentence. Change that to highly likely and ya got ya a truthful wiki. 😉
What about everyone else outside the car? It's the automotive industry version of DIE, in a sense. Save the few at the cost of the many.
Or just build a better safer power source.
Those not getting the idea deserve their Darwin Award.
Its just getting better and better with the whole EV sideshow. Thinking of getting a new EV-TBL? Contact MIC, or your nearest Mental Ward.
Now how to eject ~ 1 ton of burning thermite, 15 feet away, and not kill the innocent while the stupids... are safe in their new....powerless, stooge car. Hmmm?
They should have asked me before coming up with such stellar idiocy.

At least the linked picture is funny, and reminds me of James Bond movies ...
Quite soon noone will want to be anywhere near these vehicles, which were created with a flaw due to a flawed ideology which is deadly not just for its occupants but for whole economies.
