Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

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.

Tesla prepping Supercharger network for big growth across Europe

It'd be a nice life to be able to tour across Europe in a Tesla Model S. And that's something the California-based electric-vehicle maker is looking to enable by the end of the year. We're ready. Who's got the key fob? Tesla opened three Supercharger stations in Germany on Thursday and is aiming to string enough together to let drivers roam across the continent purely by Supercharger power by the end of 2014, Bloomberg News says. The company now has 23 Superchargers in Europe, including nine in Germany and six in Norway. Those high-powered stations can half-charge a Model S in about 20 minutes. Tesla has 97 Superchargers in North America. Tesla's most recent Supercharger deployments across the Pond merely reinforces Tesla chief Elon Musk's pledges earlier this year to ensure that all European Tesla owners would be within reach of a Supercharger by year-end, Tesla spokeswoman Liz Jarvis-Shean wrote in an e-mail to AutoblogGreen. Musk said in March that Tesla drivers would be "able to travel almost anywhere in Europe using only Superchargers" by the end of 2014. Earlier this month, Tesla started deliveries of right-hand-drive Model S sedans in the UK. Additionally, Musk estimated that the company would open a factory in Europe once annual sales on the continent reached 160,000 units. By all accounts, that's likely to be a long way off. Earlier this year, Tesla dropped the price of the Model S in Europe, though the company said that move was due to the strengthening Euro and not because of any demand issues.
