Next-gen Nissan Leaf will look more mainstream, have more range

The next-generation Nissan Leaf battery-electric vehicle will look better and go farther on a single charge, company executives tell Automotive News. How much better and how much farther remains to be seen, as does the timing on when the new version will be available to the public. Nissan executive Andy Palmer, speaking recently at the Beijing Motor Show, implied that an electric vehicle would need to have a 185-mile single-charge range to be competitive with hydrogen fuel-cell vehicles, once those arrive in larger numbers. While Nissan boosted its single-charge range by about 15 percent for the 2014 model-year Leaf, the automaker would need to double it to reach that competitive threshold. This seems unlikely for the next-gen model, but we can start making our guesses as to how many more miles Nissan will put into the pack. Regardless, the next-generation Leaf, which may come out around 2017, will at least look a bit more mainstream while it reaches for more range, Automotive News says, citing Nissan global design chief Mamoru Aoki. Indeed, the car, which will keep its hatchback layout, will likely look less angular, said Aoki, who complimented Tesla for the way it styled its Model S luxury electric sedan. Nissan's Infiniti arm could also debut its delayed luxury electric vehicle in 2017, complete with the improved battery pack. Angular looks and all, Nissan continues to increase sales in the US. Leaf sales through April were up 33 percent from 2013, to 7,272 units after more than doubling sales last year to 22,610 vehicles.

Nissan Rogue redesigned with three rows for 2014

Nissan has been on a roll lately, redesigning its core model line with all-new versions of the Altima, Pathfinder, Sentra and Versa Note released this year. But the Japanese automaker wouldn't leave out the Rogue, its second-best-selling model in the US.
Like the Range Rover Sport, Mitsubishi Outlander and Ford Explorer, the second-generation Nissan Rogue has gained an optional third row of seats for seven-passenger capability. Along with the middle and rear rows, the front passenger seat can also be folded flat for the benefit of cargo capacity, and the cabin has been redesigned for an airier look and feel.
Despite the added space inside, the new Rogue is only marginally larger than the model it replaces, with a 0.6-inch longer wheelbase offset by shorter overhangs front and rear. A lower drag coefficient ought to help reduce wind noise and improve fuel consumption as well.

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.
