Tesla Says Garage Fire Not Charger's Fault; Firemen Less Sure

cartechboy writes "It looks like Elon Musk and Tesla Motors find themselves in another PR war over the cause of a fire involving a Tesla Model S. Authorities in Irvine, CA are currently investigating the reason for a fire in a garage that, yes, contained a Tesla Model S. While the actual cause of the fire remains unknown, Tesla Motors and the Orange County Fire Authority are already publicly disputing possible causes, thought to center around the Tesla charging system. Tesla says the fire was not caused by any part of the car nor its charging system, reports Reuters. For what its worth — we've seen a version of this movie before. In 2011, investigators determined that a garage fire that destroyed a Chevrolet Volt had started away from the car, later spreading to engulf and destroy the car."

    This is where Musk's Hubris is going to be a problem.

    There's no way that he can know for sure what happened in the fire, and he's going to risk having to eat crow -- lots and lots of crow -- if he's proven wrong.

    I love the guy, but hubris is clearly among his worst qualities.

      Yes, I've heard that Musk's hubris is very large (heh, heh, heh), but perhaps he does have a point. According to the article, all the damage was done at the wall connection (not the car connection), and a review of the car logs indicated that charging was proceeding normally at the time the fire started.

      I'm going to make an assumption here that the tesla charger was probably safety tested[1] and approved for sale by UL, but what about the installation itself? Maybe California is different than the rest of North America, but most garages aren't natively wired with 240V sockets (quit laughing, you Europeans). So who did the 240V installation? The home owner or a certified electrician? Was it inspected? The article certainly doesn't say. Knowing how previous Tesla fire stories have been pounced on by the media, I'd probably do the same if I were in Elon's shoes and say the problem had nothing to do with the charger, and would change my tune later on if it turned out to be true. It wouldn't be the first time that crappy wiring has caused a house fire, and I don't think it's necessarily wrong for him to point this out.

      [1] Not that safety testing means that a unit failure can't happen, but they do check (or should check, if they are doing their jobs right) that the design is robust to various abnormal conditions, and that fail-safes are built into the product to prevent fires or other dangerous conditions in the event of a malfunction. However, all the safety testing on earth won't save you from a shitty installation...

      You're charging it wrong.

      What I find completely unbelievable in this story is that someone in California actually has their car in a garage.

      Your garage is where you keep all the stuff you can't fit into the house.

      The street is where you keep your car.

      The fire authority didn't blame the car. Here's the quote from the article:

      The Fire Authority, however, released a report stating that the fire occurred "as a result of an electrical failure in the charging system for an electric vehicle".

      Fire broke out in the garage on the campus of the University of California-Irvine on November 15. The blaze was noted by the car's owner just before 3 am, and it was promptly extinguished by fire crews.

      The incident caused up to $25,000 of damage, though the Model S itself sustained only light smoke damage. Nobody in the house was injured.

      While the Fire Authority's report stated the most likely cause was a "high resistance connection at the wall socket or the Universal Mobile Connector from the Tesla charging system", Tesla says its own data shows the car was charging normally, with no fluctuations in the temperature and no malfunctions capable of causing a fire.

      Tesla also notes that the car's charging cable was fine where it was connected to the car, and was damaged only on the wall side. This could suggest issues with the building's electrical supply, rather than with the vehicle.

      This doesn't completely rule out the charging system. The fire was started between the wall socket and the charger.

    Even if it is the charger it may be the wiring not the device itself. A friend had an attic fire that was caused by a hallway smoke detector (AC powered) of all things. The fire investigator determined the smoke detector was wired incorrectly.

    The garage fire was Nov 15, the Tesla S did not sustain any damage. The damage was all on the wall socket side.

  6. Damage on the wall side by Todd+Knarr · · Score: 4, Interesting

    If the cable was damaged at the wall side but not the car side, my immediate thought is a problem in the wall socket or wiring. I've run into that with regular outlets, old hardware causes high resistance and a very hot outlet and plug (thermal conduction through the metal parts). The most common cause is age causing corrosion of the connection plates inside the socket or looseness of the plates so the prongs of the plug don't make good tight contact with them. Either way it raises the resistance of the connection inside the socket and creates a lot of heat (it's doing exactly what the heating elements on an electric stove do). My fix is to open up the outlet and replace the socket with a new one, cleaning up and tightening the wires in the process.

    The #2 problem is the actual in-wall wiring being old and just not up to gauge for the current draw of modern electronics. In 1970 we didn't have home computers and Xboxes and the like, 14-gauge wiring was common and hooking up a modern home-entertainment center and computer would have the wiring in the wall hot to the touch. Plug a Tesla into older wiring like that and you've got a fire waiting to happen.

    Personally I never let electricity be used unless it is under my direct supervision. Whenever I run the A/C, I go outside and watch the compressor unit until it has cooled the house down. Likewise, whenever I need hot water I go out in the garage, manually turn the water heater on, and wait until the water is completely heated. I throw the main breaker and remove the power meter from the side of the house every time before going to work, the store, etc.

    You just can't be too safe nowadays.

  8. Tesla is fighting a war by sl4shd0rk · · Score: 4, Interesting

    A war over public opinion. I don't know why the struggling U.S. automakers have not embraced electric vehicles. They will make a "zombie" truck which everyone thinks is funny, but nobody actually wants. But tend to be disposed to doing everything in their power to resist that which is (probably) better for the environment and more efficient for a good portion of the population commuting just a few miles every day. Did they learn nothing from the Nissan Leaf sales?
