Nissan NV200 puts on a Bowtie as new Chevy City Express

Your eyes do not deceive you - that is, in fact, a Nissan NV200 work van with Chevrolet badging. General Motors and Nissan today announced a partnership where the Japanese automaker will build Bowtie-badged vans for Chevy dealers to sell throughout the United States and Canada. The new van, called the City Express, is expected to go on sale in the fall of 2014.
"Our fleet customers have asked us for an entry in the commercial small van segment, so this addition to the Chevrolet portfolio will strengthen our position with fleets and our commercial customers," Ed Peper, US vice president of GM fleet and commercial sales, said in a press release.
No details have been released regarding specific changes for the new City Express, though from the images released today, it's clear that the vehicle's front fascia has been reworked, and some super-sexy new wheel covers have been added. If we're honest, the NV200 wasn't all that pretty to begin with, and this, well, isn't any better. Not that looks are of primary concern in the commercial truck business, of course.

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.

Nissan working on unspecified improvements to Carwings in Leaf EV

Fly a little higher, Carwings. Nissan has been using the communication system as a way for drivers of the battery-electric Leaf to do things like use a smartphone start the charging process remotely, check the charging status or find nearby charging stations. The service was one of the tools Nissan was offering to newbie drivers of the first US mass-produced electric vehicle to better familiarize themselves with ideas like recharging your car from miles away. Now, three-plus years into the model's lifetime, Nissan is looking to get more out of Carwings, Wards Auto says, citing Nissan North America executive Robyn Williams. Specifically, Nissan is hoping Carwings will eventually be able to communicate information about the battery's health, or lack thereof (i.e. degradation) to the driver. That issue was made clear a couple of years ago when Leaf drivers in hot-weather locales such as Arizona said their batteries were losing capacity at a faster rate than advertised. Nissan North America spokesman Brian Brockman, in an e-mail to AutoblogGreen, would only say that the automaker "is always working to determine ways to offer more value to customers via telematics systems like Carwings," but declined to be more specific about any particular technological advancements. Nissan debuted Carwings in late 2010, and, among other things, the concept was novel because it let Leaf drivers compare driving efficiency with other Leaf drivers (think of it as a real silent hypermiling contest). The feature had been used as a telecommunications system on a number of Nissan models in Japan for years before being introduced on the Leaf.
