Tesla sending free replacement wall charger adapters after garage fire [UPDATE]

Tesla Motors is about to mail off a lot of packages. The California-based electric vehicle manufacturer is going to send out replacement, upgraded wall charger adapters to customers with official Tesla charging units. The reason is a recent garage fire that involved a Tesla Model S and a company wall charger, even though fire investigators said that the car was not responsible and Tesla said the wall unit did not play a role in the blaze. Tesla CEO Elon Musk said in an interview with Bloomberg today that replacement adapters will be mailed out in the next two weeks. Musk said fires and overheating adapters are "very rare events, but occasionally the wiring isn't done right. We want people to have absolute comfort, so we're going to be providing them with an upgraded adapter." The new adapter has a thermal fuse that will shut off if it gets too hot. Musk did not say why the original wall charger adapter apparently did not have a thermal fuse in the design. AutoblogGreen has asked Tesla how many adapters will be sent out and if this is a global or US-only replacement program, but as of press time, we have not received a response. We're also not sure if this will trigger a recall - the adapter is not, technically, part of the car - and hope Tesla can clarify this point soon. Tesla's first reaction to that garage fire in November was to update its charger software to automatically reduce the charge current under certain circumstances. To date, that incident in Irvine, CA is the only garage fire involving a Tesla wall charger that has been made public, but there are multiple reports of Tesla wall chargers heating up and melting, (see here, here or here), so it appears Tesla is trying to be safe rather than sorry. UPDATE: Tesla has issued a press release on this program, which is now available below. TESLA PROVIDES CUSTOMERS WITH UPGRADED CHARGING SOFTWARE AND ADAPTER FRIDAY, JANUARY 10, 2014 PALO ALTO, Calif. – A variety of factors such as corrosion, physical damage to receptacles, or inappropriate wiring or installation of electrical outlets can cause higher than normal electrical resistance when using the Universal Mobile Connector ("UMC") NEMA 14-50 adapters to charge Tesla Model S vehicles. When charging, higher than normal electrical resistance connections to external energy sources may cause excessive heating of the adapter.

1 in 7 Americans say they might buy an EV next, as sales of electrics surge

About one in seven driving Americans may likely purchase an electric vehicle as their next car, according to an AAA poll, meaning that as many as 30 million Americans may pony up for an EV within the next three to five years. While some of the motivation is environmental, survey recipients say that lower maintenance expenses and solo access to high-occupancy-vehicle lanes are also among the factors behind potentially going electric. Take a look at the AAA press release on the study here. The poll indicates that about as many people are planning to buy an EV for their next car as are looking to buy a pickup, which is impressive given that the best-selling US vehicle is the Ford F-150. And things should only improve, as about 20 percent of millennials polled said that their next car would probably be an EV. The results are all the more encouraging, at least among green-car advocates, because gas prices have fallen about 40 percent within the past five years, meaning that there's less of an incentive to go electric from a purely economic perspective. Through the first quarter of this year, US plug-in vehicle sales were up about 63 percent from a year earlier to about 39,000 vehicles. Meanwhile, when it came to AAA's annual green-vehicle awards for this year, Tesla's Model S and Model X took the large car and SUV categories, respectively, while the Chevrolet Bolt and Volkswagen e-Golf were listed atop the subcompact and compact lists. The Lexus GS 450h hybrid and the Ford F-150 took home AAA's best green vehicle in the midsize and pickup truck categories. Related Video:

Silly dyno, that Tesla doesn't have 2,000 lb-ft of torque

Torque. Lots of torque, right off the line. That one benefit presented by an electric motor over its internal-combustion sibling, and the Tesla Model S delivers it in spades. 443 spades, to be precise, or about as much as a Bentley Continental GT or McLaren 12C. But when one Emmanuel Chang put his electric sedan on a dyno up (way up north) in Edmonton, Alberta, it registered a whopping 2,000 pound-feet!
Of course that number isn't correct, as no car on the road produces that much torque. Even a Bugatti Veyron produces "only" 1,000 lb-ft, give or take. Clearly something's amiss here, but the problem the dyno had in reading the Tesla's torque apparently doesn't come down to its electric powertrain. (Nor does it have anything to do with the northerly latitude or the interference of polar winds.) It comes down to the shiny, ten-spoke alloys.
Apparently this type of dyno measures torque by running horsepower and wheel revolutions through an algorithm. It measures horsepower at the wheel (which, at 436 hp, wasn't far off of Tesla's own rating of 416 hp) and uses a stationary optical sensor interfacing with a reflector on the wheel. Every time the reflector passes the sensor, it counts one revolution. But since the Model S has shiny ten-spoke wheels (and we presume because it was taken outdoors under bright sunlight), the sensor thought that each passing spoke was one revolution of the wheel... when it was, in fact, ten times too much.
