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.

Ghosn says having Apple in EV business would be good news

Nissan once promised to have commercially viable autonomous vehicles on the road by 2020 and even certified a Leaf to test the technology in Japan. The company has since backpedaled a bit from its original lofty claims, though. During CEO Carlos Ghosn's keynote presentation at the Mobile World Congress in Barcelona, Spain, the auto exec talked more about the automaker's strategy and directly confronted Apple's rumored entry into the market. "When Apple says they are going to come with an electric car in 2020, that's good news for us," he said in his speech, according to Adweek. Ghosn took the view that any company able to grow the acceptance of EVs would help every automaker in the segment. The Renault-Nissan Alliance has been at the forefront of developing the market and claimed nearly 60 percent of the global market share last year. He was also the latest auto industry heavyweight to voice his opinion on Apple entering the industry. However, in contrast to former General Motors boss Dan Akerson, the Nissan CEO was much more welcoming. Ghosn also used the speech as a chance to clarify Nissan's plans for autonomous vehicles and seemingly pushed the original goal back by about five years. "In 10 years, you'll have cars without the driver. It is here, and it's going to transform the products," he said, according to Adweek. Under Nissan's current timeline, traffic-jam assist and fully automated parking are due in 2016, followed by automatic lane changing in 2018 and the ability to drive through intersections without a driver's control comes in 2020.

2015 Nissan Murano is the Sport Sedan Concept of crossovers [w/video]

The edgy new Nissan Murano has just been officially unveiled at today's New York Auto Show following its online debut earlier this week. Wearing sheetmetal clearly inspired by the Japanese brand's creatively named Sport Sedan Concept, the third-generation Murano continues the tradition of offering dramatic styling and surprisingly premium interiors.
With headlights and a grille that look lifted from the Detroit Auto Show concept, the Murano arguably has more design presence than it's ever had before, thanks to its sharply styled headlights and in-your-face grille. The profile is highlighted by an aggressive kink in the beltline behind the C-pillar, while the rear of the crossover sports a smallish rear window and strongly styled C-shaped taillights.
The redesigned interior isn't quite as dramatic a departure as the exterior, with a layout reminiscent of the larger Pathfinder. The material quality, though, looks to be significantly improved for 2015. There are also no shortage of optional, upmarket interior items, like heated and cooled front seats, a heated rear bench and an upsized panoramic sunroof.
