Recharge Wrap-up: Elon Musk talks autonomous cars, Renault to run ZOE in ZENN Monte-Carlo Rally

Elon Musk discussed the autonomous driving capabilities of the Tesla Model S with NVIDIA CEO Jen-Hsun Huang. He said the car is already equipped with the hardware needed for highway driving. "Even with the current sensor suite, we could make the car go fully autonomous, but not a level of reliability that would be safe in, say, a complex urban environment at 30 miles an hour," says Musk. That would require "a bigger sensor suite, and you need more computing power." Huang and Musk also discussed car hacking and artificial intelligence during the interview at the 2015 GPU Technology Conference. See the video above, and read more at Teslarati. Renault will send four of its ZOE electric cars to the ZENN (Zero Emission, No Noise) Monte-Carlo Rally. The rally, which travels through the principality beginning and ending at the Port of Monaco, is open to electric cars with ranges of less than 250 kilometers (about 155 miles). Visitors can also explore an "electric village," which includes vehicle test drives and information about the future of automobiles. The race takes place from March 20 through 22.

Bellevue Nissan now claims to have a larger group of fast chargers than any other dealership in the country. The chargers are part of the NRG eVgo network, and will be available to drivers around the clock every day of the week. They'll also be part of Nissan's "No Charge To Charge" program for Leaf customers. Washington Governor Jay Inslee was on hand at the dealership for the opening, where he called such fast charging stations, "the backbone of our future transportation infrastructure."

The proposal passed the Assembly's Committee on Environmental Conservation Tuesday. Its sponsor is Assemblyman Steven Englebright, a Long Island Democrat who says a biodiesel standard would reduce carbon emissions while boosting the state's agricultural industry. Supporters of a biodiesel standard include the New York League of Conservation Voters, the New York Public Interest Research Group and the state's Corn and Soybean Growers Association. Conventional oil companies are opposed.

DC fast charging not as damaging to EV batteries as expected

As convenient as DC fast charging is, there have been lots of warnings that repeated dumping of so many electrons into an electric vehicle's battery pack in such a short time would reduce the battery's life. While everyone agrees that DC fast charging does have some effect on battery life, it may not be as bad as previously expected. Over on SimanaitisSays, Dennis Simanaitis, writes about a recent presentation by Matt Shirk of the Idaho National Laboratory (INL) called DC Fast, Wireless, And Conductive Charging Evaluation Projects (PDF) that describes an ongoing test of four 2012 Nissan Leaf EVs that are being charged in two pairs of two. One pair only recharges from 50-kW DC fast chargers, which the other two sip from 3.3-kW Level 2 chargers exclusively. Otherwise, the cars are operated pretty much the same: climate is automatically set to 72 degrees, are driven on public roads around Phoenix, AZ and have the same set of dedicated drivers is rotated through the four cars. "Degradation depends more on the miles traveled than on the nature of recharging." What's most interesting are the charts on page seven of Shirk's presentation (click the image above to enlarge), which show the energy capacity of each of the four vehicles. When they were new, the four batteries were each tested to measure their energy capacity and given a 0 capacity loss baseline. They were then tested at 10,000, 20,000, 30,000 and 40,000 miles, and at each point, the DC-only EVs had roughly the same amount of battery loss as the Level 2 test subjects. The DC cars did lose a bit more at each test, but only around a 25-percent overall loss after 40k, compared to 23 percent for the Level 2 cars. Simanaitis' takeaway is that, "INL data suggest that the amount of degradation depends more on the miles traveled than on the nature of recharging." The tests are part of the INLs' Advanced Vehicle Testing Activity work and a final report is forthcoming. These initial numbers from IPL do mesh with other research into DC fast charging, though. Mitsubishi said daily fast charging wouldn't really hurt the battery in the i-MiEV and MIT tests of a Fisker Karma battery showed just 10-percent loss over 1,500 rapid charge-discharge cycles.

Nissan pokes fun at Tesla's New Jersey woes, then deletes Tweet

Ever have one of those moments when you release something out onto Twitter, only to think better of it a little while later and reach for that garbage can icon? If so, you are not alone. In fact, you're in the company of a certain Japanese automaker, who recently joined the ranks of those who've suffered an embarrassing bout of tweetus deletus. The Nissan Leaf social media team apparently thought it would be amusing to take a light poke at Tesla Motors and its New Jersey dealer fight woes on its Twitter feed and put together the cheeky graphic which you see above. It was originally published on the micro-blogging network accompanied by the text, "It's okay #NewJersey, you can still #GoElectric with the #NissanLEAF #EV." Funny, right? Not to everyone. The image attracted a bit of mild criticism which, to their credit, Nissan responded to saying, "It's all in #EV love." Soon, however, the original image disappeared from the @NissanLEAF feed. Luckily, we saved a copy for your edification. Rob Robinson, senior specialist of social communications for Nissan, told AutoblogGreen that the Leaf Twitter account is run by an agency, and that the tweet in question, "Was not a tweet that was reviewed or approved by Nissan. We saw it and asked them to take it down." As for the reasoning, Robinson said that, "We thought it was a discussion we didn't need to be weighing in on." While we can see the Nissan point of view, we also appreciate the attempt at being irreverent. Anything to break up the monotony of the stale toast the account usually offers up – "What would you nickname your Nissan Leaf if it was Ocean Blue?" which is the last undeleted Tweet available on the feed, as of this writing. We actually applaud the intention of the Tesla post. It all makes us wonder, though, if the social media team over there isn't in need of a little input on how they might improve its outreach. Since we know our readers are not shy in offering suggestions, we ask you to leave your thoughts and ideas for them in the Comments.
