    This shows TESLA is proactive in addressing the battery "supply problem" much trumpeted recently.


    As far as the fire, every fireman worth his pay knows that you do not extinguish an electric fire with water. I guess those dealing with the fire did not.

    in fact it's in Tesla's documentation that they can use water. But they say you need a lot of water. don't try with small quantity. ;-)

    Hi Max,


    I guess the idea of using a lot of water is to simply cool the battery until it's no longer at a temperature where it could re-ignite. I believe that the fire crew tried to get into the pack from below but their tools couldn't get through the 1/4 inch armor (which gives you an idea of the force of that object on the road - fire crews can usually rip a car apart very quickly!).


    Instead they cut holes into the pack from above, which was not the best thing to do, and the fire spread to the frunk.


    Tesla has already produced a video for fire crews but I guess not everybody has seen it yet.


    Warning: if you love your Tesla you might not want to watch this one being ripped apart! The destruction starts at about 27:40



    Several Tesla cars have been involved in accidents of one sort or another. A colleague had a small problem with his Roadster last year and this one was webcast!



    Tesla repaired the Roadster in three days and Rafael drove back to the point of the accident. He went on to win the race and become the first person ever to drive around the world in a production EV.

    Samsung should consider itself lucky they might be associated with Tesla instead of worrying about unloading their junk and tainting a strong American brand.

    That would be a perfect marriage as Samsung needs Tesla sized batteries to run its inefficient smart phones.

    This is Elon moving forward with an eye to increase the range of the cars and lower the cost of the batteries.


    Keep up the good work Elon!!!

    Tesla up big today which is a healthy thing considering the sell off. building a car with the right security features vis a vis battery technology appears to be the main concern going forward. anything burns at temperature...and lithium ion batteries explode if not built properly. Sony had this problem i think with their cell phones of all things many, many years ago. Obviously Boeing has had its own set of problems with the Dreamliner as well. the solution of regular battery replacement is to me the right way to deal with the issue. if you're talking a car and "the only problem is with the battery" this strikes me as a very solve-able problem. we'll see if the sell-off this week is the start of something more "normal" or was a buying opportunity as this company "rockets" the world forward into a new age.

    You mean (TSLA) cars don't already have a touch screen GPS map installed?

    Regarding the Tesla Model S and a fire;


    As Douglas Adams said in The Hitchhikers Guide to the Galaxy, “Don't Panic.”


    A car catches fire roughly ever 97 seconds.
    There are around 250 million cars on the road and about 260,000 vehicles catch on fire every year.


    This means that there is one fire for ever ~960 cars.
    There are about 15,000 Model S's on the road.


    So Tesla's fire risk is currently 1 in 15,000.
    I would dare say that this is a tad better than one in 960, wouldn't you?


    That being said, I really wish it wasn't related to the battery,some EV hater will use it to spread FUD, (Fear Uncertainty Doubt).

    Samsung just wants to copy whatever Tesla has so they can make a cheap imitation and sell it to people who have no taste. Beware Tesla...they will rob you blind if you aren't careful.

    A battery module started burning after getting impaled by a big piece of metal debris detaching from a semi at highway speed. Not right away. After the driver was warn by the model S to pull over and exit the vehicle. Which he did. Whole story on Elon's twitter with message from the driver invoked.


    If a gasoline powered car was involved in such an incident. There would been a rolling fireball.

    About the Model S fire
    By Elon Musk, Chairman, Product Architect & CEO
    Earlier this week, a Model S traveling at highway speed struck a large metal object, causing significant damage to the vehicle. A curved section that fell off a semi-trailer was recovered from the roadway near where the accident occurred and, according to the road crew that was on the scene, appears to be the culprit. The geometry of the object caused a powerful lever action as it went under the car, punching upward and impaling the Model S with a peak force on the order of 25 tons. Only a force of this magnitude would be strong enough to punch a 3 inch diameter hole through the quarter inch armor plate protecting the base of the vehicle.


    The Model S owner was nonetheless able to exit the highway as instructed by the onboard alert system, bring the car to a stop and depart the vehicle without injury. A fire caused by the impact began in the front battery module – the battery pack has a total of 16 modules – but was contained to the front section of the car by internal firewalls within the pack. Vents built into the battery pack directed the flames down towards the road and away from the vehicle.


    When the fire department arrived, they observed standard procedure, which was to gain access to the source of the fire by puncturing holes in the top of the battery's protective metal plate and applying water. For the Model S lithium-ion battery, it was correct to apply water (vs. dry chemical extinguisher), but not to puncture the metal firewall, as the newly created holes allowed the flames to then vent upwards into the front trunk section of the Model S. Nonetheless, a combination of water followed by dry chemical extinguisher quickly brought the fire to an end.


    It is important to note that the fire in the battery was contained to a small section near the front by the internal firewalls built into the pack structure. At no point did fire enter the passenger compartment.


    Had a conventional gasoline car encountered the same object on the highway, the result could have been far worse. A typical gasoline car only has a thin metal sheet protecting the underbody, leaving it vulnerable to destruction of the fuel supply lines or fuel tank, which causes a pool of gasoline to form and often burn the entire car to the ground. In contrast, the combustion energy of our battery pack is only about 10% of the energy contained in a gasoline tank and is divided into 16 modules with firewalls in between. As a consequence, the effective combustion potential is only about 1% that of the fuel in a comparable gasoline sedan.


    The nationwide driving statistics make this very clear: there are 150,000 car fires per year according to the National Fire Protection Association, and Americans drive about 3 trillion miles per year according to the Department of Transportation. That equates to 1 vehicle fire for every 20 million miles driven, compared to 1 fire in over 100 million miles for Tesla. This means you are 5 times more likely to experience a fire in a conventional gasoline car than a Tesla!


    For consumers concerned about fire risk, there should be absolutely zero doubt that it is safer to power a car with a battery than a large tank of highly flammable liquid.

    Mr. Guillen,


    Thanks for the support. I completely agree with the assessment to date. I guess you can test for everything, but some other celestial bullet comes along and challenges your design. I agree that the car performed very well under such an extreme test. The batteries went through a controlled burn which the internet images really exaggerates. Anyway, I am still a big fan of your car and look forward to getting back into one. Justin offered a white loaner--thanks. I am also an investor and have to say that the response I am observing is really supportive of the future for electric vehicles. I was thinking this was bound to happen, just not to me. But now it is out there and probably gets a sigh of relief as a test and risk issue-this "doomsday" event has now been tested, and the design and engineering works.

    Dear Mr. Carlson:


    I am the VP of sales and service for Tesla, reporting directly to Elon Musk, Tesla's CEO.


    I am sorry to hear that you experienced a collision in your Model S 2 days ago. We are happy that the Model S performed in such a way that you were not injured in the accident and that nobody else was hurt.


    I believe you have been in contact with Justin Samson, our service manager, since the accident. We are following this case extremely closely and we have sent a team of experts to review your vehicle. All indications are that your Model S drove over large, oddly-shaped metal object which impacted the leading edge of the vehicle's undercarriage and rotated into the underside of the vehicle ("pole vault" effect). This is a highly uncommon occurrence.


    Based on our review thus far, we believe that the Model S performed as designed by limiting the resulting fire to the affected zones only. Given the significant intensity of the impact, which managed to pierce the 1/4 inch bottom plate (something that is extremely hard to do), the Model S energy containment functions operated correctly. In particular, the top cover of the battery provided a strong barrier and there was no apparent propagation of the fire into the cabin. This ensured cabin integrity and occupant safety, which remains our most important goal.


    We very much appreciate your support, patience and understanding while we proceed with the investigation. Justin keeps me closely informed. Please feel free to contact me directly, if you have any question or concern.


    Best regards,
    Jerome Guillen I VP, WW sales and service"


    NOW THE QUESTION - what other car manufacturer responds as quickly and with such care, such as offering the S owner a loaner, sending a team to investigate and evaluate the incident and assuring all other owners of the cars integrity? They can do this because the S owner survived the accident without trauma (save losing his Tesla), many ICE car drivers are not so lucky -
