dac ::Uf imao je sreće ovaj lik. Posebno što je taj automobil MPV, takoreći porodični. Pa je dobro što je bio sam. Bio je još jedan snimak skoro sa Xiaomi automobilom. Taj čovek nije imao sreće.

Ovde je neobično da se tako odjednom (naizgled) zapalio.

Na par projekata zgrada sam sa protivpožacima komentarisao problem električnih automobila u podzemnim garažama kada se zapale, ne može da se vatra ugasi dok sve iz baterije ne izgori i onda vatrogasci maltene dežuraju i kontrolišu da se ne proširi dalje. Tako da sa pojavom sve više električnih vozila sledi ozbiljno pretumbavanje protivpožarnih propisa.

Moze se ugasiti, postoje PP aparati za pozar metala vec ihahaj godna. Problem je sto oni jednostavni i (relativno) jeftini nisu preterano efikasni u slucaju bas velikih pozara. A veliki su skupi. Mogu se napraviti jeftinijim, ali u tom slucaju se moraju koristiti veoma agresivne hemikalije, sto ih cini i opasnim za koriscenje (jer moze neko da nastrada i od gasenja).
Ukratko, problem ima resenje, ali nije bas jednostavno i kljucno trazi ogromno ulaganje para u nove tehnike gasenja pozara, jer se pozari koji su pre toga bili egzotika (alkalni metali) sada odjednom pojavljuju svuda.
Ekvivalent je kada je pocelo crpljenje i prerada nafte, pa se ustanovilo da se ne moze gasiti vodom, vec da mora da se smislja novo resenje.

Jbt pa ovo je katastrofa ako se ovo cudo ovako lako zapali! Za 10 sec buktinja. Ovaj lik je ima NEVEROVATNU srecu.

Odkrilo se da oni prave samo module, baterije pravi Nordic Nano u svojoj novoj fabrici u Finskoj.

Što se tice požara ovde je komentar vatrogasca na jedan tekst od pre par godina:

Citat: T.L.D.R version: Firefighters can easily deal with EVs



I’m a 35 year veteran firefighter, 13 years as a Battalion Chief, so I know what I’m talking about. EV fires are a concern, but not a huge problem. True, firefighters need to be informed about handling EV fires, but they are a kin to other types of situations we handle, I won’t say on a regular basis, but often enough that we have procedures to reference to deal with them.

Myth #1 about EV fires is that we need “lots and lots of water” to extinguish an EV fire. That of course depends on your definition of “lots” but I’ve seen reports that it “took 40,000 gallons of water” to extinguish an EV fire. I can assure you, that’s ridiculous. Now, I’m not going to assert that firefighters haven’t used too much water on an EV fire, just that if they did, it was out of ignorance about how to handle them. I train my crews to treat a burning battery the same way we’d treat a burning propane or natural gas leak that can’t be plugged (this isn’t an unheard of situation) Firefighters know that we shouldn’t extinguish a burning gas leak if we can’t stop the leak. The fire burns off the hazard instead of allowing a cloud of unburnt flammable gas to build up in an area that may have another ignition source in the area (sometimes blocks away!!!) THAT is a disaster waiting to happen. So, what we do to protect exposures (adjacent property and structures) is use enough water to extinguish the ordinary combustibles close to the gas leak fire, then a fog pattern fire stream to keep those surrounding combustibles from being reignited by the gas flame that remains burning until the gas is cut off. The same for EV batteries.
When we first arrive we’ll use high volume fire streams to extinguish the burning plastics, rubber, etc that have been ignited by the battery fire. It is wise to consider the car as totally destroyed and not attempt to try and save any of what’s left of it. Let the car parts burn themselves away while we keep the fire from catching unburned things on fire. Now the object is to cool the case of the battery to attempt to slow/halt the thermal runaway from heating other cells in the pack. This does NOT take a lot of water. Enough to keep a thin film of liquid water on the surface of the pack is all you need. If all the water is boiling away in steam, that’s not enough, but the kind of stream you can get from your garden hose would be adequate.
I’ve seen firefighters hook up a tow chain to a burning EV to get it away from unburned fuels (pulling it out of a garage) so that the fire emanating from the EV packs fire vents isn’t impinging on salvageable items. Moving fuel away from the fire, or moving the fire away from the fuel is a tactic we use all the time. If a car is a burnt hulk of melted metal out on a lonely road by the time we arrive, we might opt to let the entire thing burn without using any water. 


Myth #2 is that the car needs to “lifted into giant tanks of water”. Uh... no. I don’t know of any EV manufacturer who suggests that. An EV with a compromised battery pack should be stored in an open area away from other combustibles until it’s sure no additional heating is occuring.

Much of the rest of this article reads like anti-EV whiners nit-picking every little criticism they have with EVs or Elon Musk. Complaining that there’s no emergency guide to the Model Y, if it was true when the article was published (Tesla has an online copy today [Link mogu videti samo ulogovani korisnici] ), doesn’t matter because there was one for the Model 3, an identical car as far as emergency responders are concerned. “...implied there was magnesium in a part of the car that did not, in fact, contain magnesium” is insignificant and meaningless, as manufacturers change materials all the time. Warning firefighters that there might be water reactive combustible metals is worth mentioning, if they’re not there in some versions doesn’t need to be warned about. It’s kind of like “may contain peanuts”. That there are no peanuts in this package isn’t a hazard to be noted.

Delimicno tacno, jer pricas o pogresnim baterijama

Ovo vazi za baterije u kojima se nalazi litijum, tipa dugmastih,jednokratnih AA...

EV uglavnom koriste Li-ion baterije, ne litijum-metal, pozar je od zapaljivih gasova (etilen, metan..) koje se koji se pri pregrevanju oslobadjaju, ne reaguje litijum.

Uprosceno, pozar je slican benzinu uz dodat sopstevni izvor kiseonika i grejac.

Kanadjani hoce kineze
Citat:Carney: To make Canada a leader in electric vehicle manufacturing, we’re working to attract significant new joint-venture Chinese investments.
And as our domestic sector builds up, we’ll allow a limited number of EVs from China into the Canadian market — less than 50,000 next year — providing more affordable, energy-efficient options for Canadians.

sa teslom modelom Y u EU ima dosta problema.

Tesla Model Y named worst car for reliability in Germany’s major TÜV report
[Link mogu videti samo ulogovani korisnici]

a kod danaca:

The Tesla scandal continues: Almost every other Model Y fails inspection ", FDM presents the results of the Danish Transport Agency's four-year inspection in Denmark. The Danish Transport Agency is the equivalent of the Norwegian Public Roads Administration in Norway.

New passenger cars must undergo technical inspection after four years, and in 2025 it was therefore the 2021 models of Model Y - and other makes and models - that were inspected.

The result is downright disappointing for Tesla. 2,394 Model Ys were inspected in Denmark in 2025. A full 1,069 of these passed, writes FDM. This corresponds to 45 percent.


The faults that are common on the Tesla Model Y are found in the steering, axles, wheels, tires, brakes and lights, FDM states. The most common fault is looseness in the suspension, which was found on 22 percent of Tesla Model Ys.
