How to get incredibly accurate information on your EV's charging power

One would think that paying about $300 to receive a bit of bad news about electric-vehicle charging would be counterproductive. But the fine folks at Teslarati believe that truth is beauty, and they're willing to pay a little extra for the straight dope. There are always losses when taking power from the grid and shoving it into an EV's battery pack. The question is how big are these losses. Teslarati calculated digital read-outs from the dashboard of their Tesla Model S all-electric sedan and found that Tesla builds in about a nine percent efficiency loss when it comes to recharging the car. But the blog thought the Tesla couldn't know exactly what was transpiring between the wall and the battery, so it footed the bill for about $300 to install a digital submetering unit from EKM Metering. With a little calculation, Teslarati was able to figure out after a couple of recharging rounds that the efficiency loss per recharge was closer to 15 percent than nine percent. That means that, instead of paying about 48 cents on the dollar relative to filling up an economy car (factoring in the AAA average price of $3.66 per gallon), Tesla owners are paying about 52 cents on the dollar. Not much compared to paying upwards towards $100,000 for the vehicle itself, but, hey, every cent counts, right? Get all of the details here.

Tesla to be named Tuosule in China

Tesla is not Tesla anymore, at least in China. The Palo Alto-based manufacturer has apparently given up on the fight over its name, for the time being. The name "Tesla" was trademarked by one Zhan Baosheng in 2006, while the American EV company didn't attempt to claim it until 2009 (we reported on this development a few weeks back).
Of course, trademark squatters aren't really a new thing, particularly in China. Earlier this month, we told you about a car company that is attempting to patent a Volkswagen design before the German manufacturer could even bring it to market.
Since the California electric car manufacturer can't go by Tesla in the Asian automotive market, it's reportedly elected to be known as "Tuosule." First reported by InAutoNews, the Tuosule name apparently comes from a transliteration of "Tesla" to a dialect of Chinese spoken in Hong Kong. This was the second time Tesla has gone to court over its name. The first time was to reclaim the name "Tesla Motors," which it achieved by purchasing the name from its owner, Qiao Weiwei, but that name apparently isn't licensed for automotive use.

Tesla Wins Technology Of The Year Award

The winner of AOL Auto's second annual Technology Of The Year award ran away with the votes for the award, clearly surpassing all of the other contenders. We're giving it to Tesla's Supercharger Network, which today is made up of 54 charging stations in the U.S. that can provide about half an electric car's full charge in just 20 minutes, compared with the 8-hour charges from conventional outlets. The editorial staff agreed that the Tesla Supercharger is a game changer, and easily deserves to be called the Technology Of The Year. "Tesla is showing, again, that there are amazing technological breakthroughs to be made in the EV game, and are kind of making the rest of the industry look bad," said Sebastian Blanco, editor of Autoblog Green. AOL Autos' Multimedia Director Adam Morath agreed that the Supercharger is a game changer. "With the Supercharger, Tesla is tackling the tired arguments against the electrification of the automobile head on by addressing range, charge times, charger accessibility and clean energy production (the Supercharger is powered by solar energy, not coal) all in one stroke," he said. The panel reviewed more than 40 qualified submissions from readers, editorial staff and industry, the panel of judges named the following as finalists: Chevrolet MyLink Valet Mode; Infiniti Backup Collision Intervention; Tesla Supercharger Network; Volvo Pedestrian and Cyclist Detection with Full Auto Brake; Mopar In-Vehicle Wireless Charging for Portable Devices; and Mercedes-Benz Intelligent Drive. Superchargers are located across the U.S., making it possible for an electric car driver to take a coast-to-coast trip. They're strategically placed near amenities like roadside diners, cafes, and shopping centers so drivers can stop, eat, and come back to a charged electric car. Most of the staff did not get to test the Supercharger network firsthand, but have been following it closely. A former TRANSLOGIC reporter tested it, and said it works as promised. And Blanco has been following the Supercharger's development quite closely, and said he hasn't heard a single complaint from users in the U.S. or Europe. Jeremy Korzeniewski, Managing Editor of Autoblog, said the Supercharger levels the playing ground, making electric cars almost as convenient as gas-powered cars. "There's simply no way the average consumer is going to consider putting an electric vehicle in their garage if there's no way to refuel it on the go," he said.
