This feels like some alt-right anti EV car propaganda

[–] Timecircleline@sh.itjust.works 57 points 1 year ago (1 children)

To me it looks like a training excercise. Electric car fires are different from ICE fires

[–] rcmaehl@lemmy.world 27 points 1 year ago (1 children)

Yep. This was from a manufacturers video. Just the idea of a fire blanket was a bit funny for me as it's just not something you'd think of.

[–] Pyr_Pressure@lemmy.ca 3 points 1 year ago (1 children)

You'd need a big blanket for a Tesla semi

Or, reality. Wait till things really start getting hot globally and the battery manufacturing is sold to the lowest bidder for more ceo profit. I personally have no issues with Evs, but knowing how batteries fail..Esh..it's a very spicy pillow

Wait until you find out how a tank of gasoline fails

[–] CADmonkey@lemmy.world 8 points 1 year ago (2 children)

Fire departments across the US have the tools and chemicals on hand to deal with a gasoline fires.

Electric cars are fairly new (that Baker from 1910 doesn't count, because it had lead-acid batteries and nobody drives one) and aren't as common as ICE cars, so fire departments haven't all caught up. Outside of huge cities I imagine a fire department doesn't have the equipment to deal with a battery fire.

Just spray it with water!

[–] pipe01@lemmy.pipe01.net 2 points 1 year ago

Yeah fair enough, hopefully with time this will be less of an issue

[–] Fiivemacs@lemmy.ca 2 points 1 year ago (2 children)

The tank doesn't just explode when it fails..still needs ignition but ok

Wait until you see a gas tank spontaneously combust (you won't). The same way you won't see a gas tank explode when overfilling it or puncturing it.

Have you never heard of the Ford Pinto

All but the highest end EVs will likely switch to a LiFePO4 battery chemistry, this chemistry is much more stable under destructive conditions and are less prone to combustion and thermal runaway.

[–] nxdefiant@startrek.website 7 points 1 year ago

And the only penalty is about a 10% energy density loss. The chemistry also charges / discharges on a very flat curve, which means it's not sufficient to monitor voltage levels and temperature to know the current charge state, you have to also monitor power-in / out and time and make a best guess, which requires semi regular calibration.

The upside is that you can always charge to 100% and it has almost triple (I think) duty cycles compared to traditional liOn

I have issues with EVs. People are acting like this is the cure for climate change when they're almost as bad for the environment as conventional cars when you include the environmental cost of manufacturing and the energy mix of the grid that powers them.

Why can't we be sensible and invest in trains, trams, subways and bicycle infrastructure rather than engaging in techno-fetishism?

[–] Zetta@mander.xyz 9 points 1 year ago (2 children)

Um they are not almost as bad as ICE vehicles. Even including emissions during manufacturing it still only takes a handful of years for most EVs to be more environmentally friendly than an ICE vehicle.

[–] JohnDClay@sh.itjust.works 3 points 1 year ago (1 children)

Exactly. It depends on your local energy mix, but I think it's better after like 4 years worst case scenario. Here's a video we with more info. https://youtu.be/6RhtiPefVzM?si=tNZr23eRFk41jQ7a

Cars will still have more emissions than busses or trains, especially electric, so we should invest in those.

It takes at least decade for the carbon from manufacturing to be offset by the lack of emissions from the ev’s daily operation.

Assuming zero carbon electricity generation used in the ev. Local electricity mix will adjust that number up.

If you really want to have a bad time: we don’t have enough lithium to replace even half the cars currently on the road, not counting all the other uses for it aside from ev batteries.

The only two ways out of this are fewer cars or fewer people. When someone suggests the latter path, be sure to ask them who and why.

This is already happening in Florida after the hurricane flooded some Teslas. Apparently lithium ion batteries don't like salt water.

An aside: I support EVs and a renewable future. It's important that we acknowledge and address these issues in this early stage of adoption. Also, call your senator and have them support the Motorcycle Parity Act so I can afford a Livewire S2.

[–] Cruxifux@lemmy.world 19 points 1 year ago (13 children)

Unlike gas cars, which never start on fire.

[–] jetsetdorito@lemm.ee 7 points 1 year ago

EVs are a lot harder to put out

[–] CADmonkey@lemmy.world 5 points 1 year ago

Unlike gas cars, which every single fire department in the US has been dealing with for over 100 years, electric cars need different equipment to put them out. Not all fire departments have the stuff on hand for battery fires. In 20 years this will probably change.

[–] ShittyRedditWasBetter@lemmy.world 1 points 1 year ago* (last edited 1 year ago) (1 children)

Please try to ignore the facts and pretend like it's not significantly harder to contain a fucking gas fire and significantly less dangerous. Disingenuous bullshit.

[–] Cruxifux@lemmy.world 2 points 1 year ago (4 children)

Did you mean to say easier?

As someone who doesn't understand a thing about cars, and evs in particular- wat? Do they combust spontaneously?

[–] Beetschnapps@lemmy.world 12 points 1 year ago* (last edited 1 year ago) (1 children)

No. In fact they are typically quite safe but there are some edge cases that pop up given the size and power of the batteries. E.g. Recently it was reported in Florida that some EVs had similar battery issues as a result of hurricanes flooding them with salt water. Thats not a normal occurrence. It makes sense that salt water and batteries aren’t totally simpatico, but more importantly for this to happen you had to leave your car by the ocean in a hurricane, not a spontaneous thing.

Conversely I had a friend driving a brand new ford fiesta and one of the front wheels just came off at speed on the highway…

[–] malloc@lemmy.world 4 points 1 year ago (1 children)

I can see flooded EVs susceptible to electric shorting. But I haven’t read or seen any reports of combustion simply due to exposure from salt water. Maybe those vehicles were pierced by some object during hurricane?

Do you have a source?

Also modern ICE vehicles not immune to electrical shortages due to heavy water exposure. Most if not all have ECUs and other electronic equipment that is sensitive to water exposure.

[–] KaiReeve@lemmy.world 4 points 1 year ago* (last edited 1 year ago)

It's fairly common for ocean-front condos in Florida to have parking garages that are below sea level. If the surf rises enough to breach the seawall then it will flood the garage levels and not the condos where people are likely sheltering. This is most likely where those Teslas were parked, so it's unlikely that they were subjected to the hurricane force winds.

[–] Rivalarrival@lemmy.today 3 points 1 year ago

No, they do not spontaneously combust. They just burn differently. They electrolytically produce very large quantities of flammable vapors and oxidizers. Because they are not entirely reliant on atmospheric oxygen, it is extraordinarily difficult to extinguish them.

It takes 10+ times as much water to extinguish a battery fire as an equivalent petro-fuel fire.
