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.

2015 Nissan Juke

I didn't always like the Nissan Juke. When it launched in 2010, I just couldn't get over the way it looked – it came across as super weird, and kind of hideous at first blush. But I slowly warmed up to the funky little crossover/hatchback/thing, and after spending some time behind the wheel, I really learned to love Nissan's small wonder. It's a genuine hoot to drive, offering hot hatch-like thrills in a package that doesn't look like anything else on the road. The Nismo and RS models that followed only increased my ardor for the turbocharged Juke, and now, I find myself smiling whenever I see one of these little guys bombing down the road. Going into 2015, Nissan hasn't really made major changes, but there are a host of smaller improvements on hand to make it a more well-rounded vehicle than ever before. And to up the funk factor for the new year, there are a slew of customization options now available to customers through the Juke Color Studio – for better or worse. Following my first drive of the third-generation Nissan Murano in Napa Valley, I took the refreshed Juke for a spin to see if the 2015 model year improvements still make for a car that's good to drive and easy to use, while bursting with the same personality that slowly won me over in the first place. Drive Notes Powering the Juke is the same turbocharged, 1.6-liter inline-four as last year, with 188 horsepower and 177 pound-feet of torque on tap. I've always liked this engine – it's punchy and feels good when being worked via the 2014 model's six-speed manual transmission. There's lots of power down low, with a nice bit of boost mid-range through each gear. Altering the drive modes between Normal and Sport heighten this, and honestly, the turbo/manual setup in this front-wheel-drive Juke was kind of hilarious – a real treat. Sadly, Nissan will no longer offer the manual transmission on non-Nismo Juke models for 2015, so you're stuck with the continuously variable transmission. Bummer. In sport mode, the usually good Xtronic CVT tends to rev high and hold itself there – a tendency of older such transmissions that's seriously off-putting, especially for enthusiasts. Still, the Juke is available with a choice of either front- or all-wheel drive. The FWD Juke is fun, offering decent amounts of grip with a hint of predictable understeer. But I've always liked the four-season factor of the AWD Juke.

Recharge Wrap-up: video touts Volvo electric buses, Nissan and BMW build EV chargers in S. Africa

Volvo is touting the advantages of electric buses in a new video. The short film, called Route 55, promotes the ElectriCity Project for public transport, and, more specifically, the new electric bus route in Gothenburg, Sweden. The new route debuts June 15 using Volvo electric and hybrid buses. In the video, two teenagers are seen waiting for the bus. As one boards, the other asks her out from the sidewalk, but she can't hear him over the noise of the diesel bus, which then closes its doors and drives away. The film asks, "What if this bus had been silent?" See the video above, and read more in the press release below. BMW and Nissan will build an EV charging network across South Africa. Through 2017, the two automakers will build fast-charging and AC stations around the country in order to encourage the adoption of EVs. Nissan has been selling the Leaf in South Africa since 2013, and BMW introduced the i3 and i8 in March. "In order for the introduction and expansion of electric vehicles as well as plug-in hybrid electric vehicles to be successful in this market, we need to work together," says BMW South Africa Managing Director Tim Abbott.

The fleet of vehicles includes the Nissan Leaf and e-NV200, as well as the Renault ZOE, Kangoo ZE and Fluence ZE. The entire passenger car shuttle fleet will use all-electric vehicles as some 20,000 UN attendees descend upon Paris from November 30 to December 11. "Thanks to the Alliance's fleet of 100-percent electric vehicles, it will contribute to our goal of achieving a carbon neutral event," says French Minister of Foreign Affairs and International Development and COP21 President Laurent Fabius. "The technology of electric vehicles helps reduce greenhouse gases in the transportation sector efficiently." Read more from Renault. Visa will be the official title sponsor of the Formula E London ePrix. Officially called the "2015 FIA Formula E Visa London ePrix," the races on June 27 and 28 will be the last of the electric racing series's inaugural season. Visa Europe will award the Visa Fastest Lap trophy after the each round, and will have interactive activities at the race's eVillage.
