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.

Watch Formula Drift Championship leader Chris Forsberg drift a 1975 Datsun 280Z

Chris Forsberg won the Formula Drift Championship in 2009, was in the catbird seat to win it last year until the final race of the season and started this year's season with a win at Long Beach. That is how he can be provide the example for Clarion USA's tagline, "Dream like a champion."
In this three-minute video for the audio components manufacturer, Forsberg gives up the race suit for a corporate suit, then takes time out of his commute to think about what he'd rather be doing. In a 1975 Nissan 280Z with a turbocharged 2.0-liter Skyline RBDET20 engine. We're sure this has never happened to any of you before.
You can watch how dream begins - and suddenly ends - in the video below.

Nissan Juke facelift spied during testing

The Nissan Juke boldly reinvented the subcompact crossover for the modern age a decade after the niche's progenitors - the first-generation Toyota RAV4 and Honda CR-V - grew well beyond their original, diminutive sizes. Since being introduced in 2010 as a 2011 model, the Juke has proven to be a huge sales success for Nissan in Europe and quite a success here, too. A modest refresh is planned for the 2015 model year of Nissan's tiniest crossover, and our spy shooters have caught an early glimpse.
The exact changes are not easy to spot, but you can bet that anywhere you see camouflage, a modestly new look is hidden underneath. The biggest change up front is the narrower grille that appears to no longer extend over the headlights. Assuming this isn't just a clever disguise, the change gives the impression that the Juke actually has distinct headlights, instead of massive fog lights. The more angular front air dam also appears to extend slightly lower than before, and the intakes appear to be revised as well.
The changes to the rear are even more minor. You can still see the outlines of the boomerang-shaped headlights, and any alterations to the rear bumper are impossible to spot behind the camouflage tape. It's also unclear at this point whether the interior will receive any refinements or new options.
