Figuring out exactly how much it costs to charge Tesla Model S

Is the Tesla Model S an electricity guzzler? One driver trying to answer that question says it does gobble down more juice than previously thought, but it's not time to make Hummer jokes just yet. First, the goal: Tesla's claims that properly set up home-charging stations can get about a 91-percent efficiency rate. Rob M. from Teslarati has been diligently tracking electricity used by his home charging station – made up of a NEMA 14-50 outlet that was professionally installed and Tesla's Universal Mobile Connector (UMC) – since June, as we reported here. The results for the month that ended July 21 revealed that the Model S was taking in about 82 percent of the electricity it was pulling from the system, indicating an 18-percent loss of electricity. Most EVs are thought to charge at an 88 to 90-percent efficiency rate. The downside to his results? About $26 more per month in electricity costs than previously estimated on about 2,400 miles worth of driving. There is a positive upshot, though: his monthly fuel savings totaled about $334 compared to driving an internal combustion engine vehicle. These early results are intriguing, and make us wonder... Is anyone else checking in on their Model S charging efficiency?

Learn hidden Tesla Model S safety facts from this first responder video

We all know that crashes can happen in a Tesla Model S. What not all of us know is how to approach a smashed vehicle in such a situation. That's where a new video, Emergency Response To Electric Vehicles, with Brock Archer and Ron Moore from Boron Extrication comes in. The training video, put together with the help of Tesla Motors, does not feature any spectacular crash footage (you can get that here) but does cover things like demystifying the dangers of an EV that has crashed in a puddle of water, the way an EV's body structure could fracture while being cut and the basics of electricity flowing through a circuit. It also discusses a few pertinent questions: How do the two electrical systems (12V low-voltage system and the high-voltage powertrain system) affect first responders trying to cut their way into the passenger cabin? Do first responders know all of the different ways an EV tells you if it is currently receiving a charge when it is plugged in? How can you locate the different types of batteries? There's lots here that applies to all EVs in the 37-minute video, not just the Model S, so if you want to know more about how safe - or unsafe - they are after an accident, watch the whole thing below.

Elon Musk is Vanity Fair's number one 'disrupter'

Elon Musk's leadership of Tesla Motors has transferred well to pop culture. In this case, the electric-vehicle maker's CEO has popped up as Number 1 on Vanity Fair's annual "disrupters" list. Musk jumped from No. 5 last year and for 2014 came in ahead of Google co-founders Larry Page and Sergey Brin; Apple's Tim Cook and Jonathan Ive; and Facebook's Mark Zuckerberg. Pretty healthy company. Vanity Fair pegged Musk's net worth at $12.9 billion, thanks in part to Tesla's stock climbing up about 70 percent in the past year (despite a recent dip) and has surged by a factor of 16 since the initial public offering in 2010. It also can't hurt that Tesla scored about $1.2 billion in government incentives when it agreed earlier this month to build its gigafactory in Nevada. Additionally, Vanity Fair feted Musk for his involvement in both space-exploration company SpaceX and home solar-panel provider SolarCity and described Musk's marital status as "complicated." VF just loves that stuff. Perhaps most impressive is the fact that Musk was the only auto executive to end up on either the publication's "disrupters" list or its "powers that be" list. The latter was headed by Fox's Rupert Murdoch, Walt Disney's Bog Iger and Comcast's Brian Roberts and Steve Burke. You can read Vanity Fair's write-up of Musk here.
