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.
Garage fires aren't a very common topic on Slashdot.
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.
I always keep my linseed oil soaked rags piled up together in a nice dry place covered in sawdust.
Not a bad guess (still, I'll wait for the official report) in a garage, since most people don't seem to realize that an oily rag will if left for a few hours. You can try it yourself.
Whoops, butchered that comment. Meant to say an oily rag will spontaneously ignite if left for a few hours. You can try it yourself.
"garage fire started by improperly installed electrical outlet" just doesn't get you as many clicks.
The garage fire was Nov 15, the Tesla S did not sustain any damage. The damage was all on the wall socket side.
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.
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?
