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 GT-R Nismo gets official

Behold the 2014 Nissan GT-R as dressed by Nismo and inspired by the GT3-spec race car that competed in this year's Nürburgring 24-hour race. Called the "ultimate iteration of Nissan's GT-R supercar," power goes up by 55 horsepower to 600 hp with updates like high-flow, large diameter turbos, and torque is "over 480 pound-feet," which means it's risen by at least 35 lb-ft.
Helping to keep it right-way up and pointed in the right direction are a race-tuned suspension with a larger, hollow anti-roll bar, custom Bilstein DampTronic dampers and the use of high-rigidity bolts. Outside, a new aero package from the wider front carbon bumper to the carbon rear spoiler above a longer, tapered rear bumper creates an additional 220 pounds of downforce at 186 miles per hour compared to the standard GT-R. Rumors of a 'Ring time of 7:08 abound, we'll get the truth - and we assume some video - very soon.
The bodyshell construction uses adhesive to improve rigidity, and behind those windows are carbon fiber Recaro buckets - in Europe and Japan, at least - and an Alcantara-wrapped wheel. It goes on sale next year, but you can get to know more about it right now in the press release below.

Nissan, Mitsubishi team up for $14,000 electric car

Last November, the Renault-Nissan Alliance and Mitsubishi announced a partnership to build some tiny electric vehicles for the Japanese market. Well, the partnership is going to build more than that (like the Nissan Dayz, pictured above in Roox form, and the Mitsubishi eK wagon), but we're most interested in the upcoming plug-in results. Those results are not here yet, but we now know that the 50-50 joint venture is moving forward and that the first "kei car" EV from the project is now due in fiscal 2016, according to the Nikkei Asia Review. The makers of the popular Leaf and i-MiEV electric vehicles say that the new small EV will be the cheapest EV on the market when its released, potentially priced at 1.5 million yen (around $14,700 US). Currently, the i-MiEV is the cheapest EV option in Japan, with a 2.5-million yen starting price (just under $24,500 US) before incentives. Taking a good $10,000 of the purchase price is likely more than enough to counter the smaller size and, perhaps, more limited amenities.
