    Exclamation TX-Self driving Tesla with no one in driver's seat, crashes, incinerates both passengers

    Tesla Car With No One In The Front Seats Crashes And Bursts Into Flames, Kill Both Passengers While Self Driving

    https://vidmax.com/video/203801-tesl...e-self-driving

    Two men died after a Tesla (TSLA.O) vehicle, which was believed to be operating without anyone in the driver's seat, crashed into a tree on Saturday night north of Houston, authorities said.

    “There was no one in the driver’s seat," Sgt. Cinthya Umanzor of the Harris County Constable Precinct 4 said.

    The 2019 Tesla Model S was traveling at a high rate of speed, when it failed to negotiate a curve and went off the roadway, crashing to a tree and bursting into flames, local television station KHOU-TV said.

    After the fire was extinguished, authorities located 2 occupants in the vehicle, with one in the front passenger seat while the other was in the back seat of the Tesla, the report said, citing Harris County Precinct 4 Constable Mark Herman.

    Tesla and the National Highway Traffic Safety Administration did not immediately respond to a request for comment.

    Here's an updated flier for first responders dealing with an EV fire/crash from DOT dated 2014

    http://www.nhtsa.gov/staticfiles/nvs...ireDept-v2.pdf

    While they note that damaged or burning battery packs may contain residual high voltages and leads and cables are to be avoided, the best and only solution seems to be "surround and drown".

    A "B" class extinguisher could be used to knock down visible flames long enough to extract or rescue occupants, but without massive amounts of water to cool and stop a thermal runaway, your only other choice is to retreat, isolate and let it burn.

    Apparently these batteries are not too different from lead acid batteries, in that they have plates, screens and spacers all wrapped around one another and submerged in an electrolyte solution. Rupture and short circuiting of these plates during charging or in crash, causes electrolyte boiling, offgassing then explosion and fire.

    Here's a quick read on it:

    Water will just make steam till the batteries are depleted.
    Pete, here's the problem with the damn things.

    It's not the arc or an external short causing the fire, it's an internal runaway reaction that cannot be stopped without massive amounts of cooling water.

    The plates contain energy, the electrolyte allows energy to drain or charge the battery by allowing ionic flow through it from plate to plate.

    If that plate separation is compromised, and they make contact in a short circuit, or the electrolyte is lost and they heat up and melt together, a fire is inevitable as all the energy contained in the plates is now rapidly released at the short circuit, and expands as the area gets hotter, the components melt together and the electrolyte gasses off.

    Which leaves the only way it can be put out is to drown it with water to cool the components below explosion, BLEVE or LEL limits.

    In my reading and personal experience with these things (had a 20 foot TEU container with a bunch of them in it catch fire about 15 years ago, had a deuce of a time with it) the analogy is very similar to a runaway nuclear reaction.

    And again you are correct. Been a long time since military fire training and was posting quick. Perhaps Tesla should send a memo to departments. Or we could invent a water, powder, foam spray. We kill the trinity outright instead of breaking just a leg.

    ETA: After reading AF's post's I've changed my mind. You may well be incorrect on this.

    Well, there is the billion dollar winner, AF and Pete. The fire triangle consist of ignition source, fuel and oxygen. Cut any leg and the stool falls.

    So, get your two heads together. Come out with a non-combustible foam that will choke out oxygen from a burning battery and I will huck it in late night television

    I'd be looking at a Halon 1211 (yeah yeah yeah I know...or a suitable "green" equivalent) foam system combined with a liquefied refrigerant.

    Cooling is essential and absolutely key to knocking one of these battery fires down. That's why they keep re-igniting. You think you got it knocked down, overhauled and out, meanwhile the shorted plates are still there, still discharging rapidly and creating fresh heat.

    Maybe a portable fire tent as well.

    Cover the vehicle with the tarp or tent, secure it as best as possible and flood the now enclosed space with 1211 Halon foam and liquid R426 or something similar.

    Hopefully it was some rare malfunction that can be quickly fixed.

    In theory, there can be other nefarious possibilities that appear very improbable based on reporting in this case.

    On a side note, good Anti-Virus software should also be made available with such sophisticated devices at the start of mass production.

But one new car-hacking trick illustrates that while awareness helps, protection can be extremely complex.

    • Internal systems are down, making it impossible for staff to process orders
    • On the customer side, some users cannot connect to their car in the app
    • The US and Europe are experiencing issues with what appears to be the app
    • The outage follows Tesla's Battery Day that many investors deemed a failure

    The batteries used today did not exist 15 years ago..
    Not the same batteries.. and also NO PLATES.. These batteries are smaller than D cells..and similar configuration. and hold 3.6 volts each.



    Only problem with these ones is over heating when Over Charging.. and most Fires had been caused by that.. improper Charging.
    Tesla Batteries are in a liquid Water Jacket that both Warms or Cools batteries as necessary..

    Hi voltage Arcs are lighting other materials on fire,,, not the batteries themselves..

    Overcharging enough to cause a fire takes some pretty deliberate Stupidity.

    The first commercially viable Lithium ion batteries were introduced by Sony in 1991.

    I had a half a pallet of the damn things fall off another pallet inside a half size shipping container. They were adopted early by the oilfield industry for remote and emergency backups for all manner of system controls. This was back in 2006 or 2007, I'd have to look at my logs to know for sure, happened right around new year's day...so "give or take" 15 years. One of them fell onto a sharp pipework guard of other piece of cargo, pierced the case and started a thermal runaway fire that was contained ultimately by snagging the container sling and having the crane operator pick it off the deck and submerge it into the ocean until cooled.

    Not the same batteries. These batteries are smaller than D cells..and similar configuration. and hold 3.6 volts each.
    No, of course not, Tesla...all EVs in fact, have much larger batteries with thousands of cells.

    Here is a small cross section of a Tesla battery pack.



    and also NO PLATES..
    We're picking engineering nits here brother.

    Yes, they are not flat "plates" as in a lead acid battery, they are wrapped coils, sandwiches, of electrolyte and anode and cathode and insulator materials.

    But they still call transistor anodes "plates" from vacuum tube technology, same as battery cel "plates" in that they are chemical receivers and pitchers of electron flow across an electrolytic or semi conductor membrane.



    Only problem with these ones is over heating when Over Charging.. and most Fires had been caused by that.. improper Charging.
    You can't over charge them as far as I can tell.

    The charging process is completely automated and out of the operator's control.

    Tesla Batteries are in a liquid Water Jacket that both Warms or Cools batteries as necessary.
    Yes and that seems to be part of the problem with the ones that have spontaneously combusted while charging...they seemed to suffer some failure of the cooling system.

    Hi voltage Arcs are lighting other materials on fire,,, not the batteries themselves..

    Overcharging enough to cause a fire takes some pretty deliberate Stupidity.
    Failure of the cooling system and external shorting would not account for the repeated instances of re-ignition of the battery pack.

    That amount of heat is caused by one thing only: the runaway chemical/electrical reaction going in inside the battery and it's individual cells.

    And it will continue to go on, until the fuel is exhausted, the cells all discharged or the whole thing swamped with enough water to cool and stop the runaway reaction.

    Very true. We used to have a Kaiser plant in town which worked with potassium, and it had huge red letter signs all over the outside of the building warning the fire department not to use water.

    Quote Originally Posted by pcosmar View Post

    Different sizes, configuration and chemical, and probably different names for the components, but batteries work the way batteries work. There are parts of each cell that do exactly what the old school lead plates do.

    Breaking these packs down into a bunch of small cells instead of having one huge cell may slow down the disaster when they get damaged, but if they were truly protected from each other with real firewalls the car would be even more grossly overweight than it is. The separate cells certainly don't function like watertight compartments on a ship. And Tesla clearly hasn't thought of making parts of the battery pack easy to jettison, so the damaged and undamaged cells can be separated to minimize the fire.

    As for putting your lives in the hands of a three cent grain of sand programmed by a techie nerd who very likely can't merge properly himself, well. Hate to speak ill of the dead, but their fate is just what I expected would happen. Human brains are still the most adaptable and discerning computer yet devised, and half of humans can't drive. I know for a fact Google's efforts to devise self-drive AI picked personnel exclusively for their programming skill, and whether they even had driver's licenses or not was not considered relevant. They were housed near public transit they could use to go to work "teaching" inanimate objects to "drive". It isn't just that the technology isn't ready, it's that these corporations have nothing but contempt for the skill they're trying to impart on these machines.

    and I would do such on my own build.. Airbag sensors coupled to the contractors should do the trick.

    Yeah, an auto disconnect wired up to the crash sensors would be a leap forward, like you said, battery to vehicle and then from module to module in the battery.
