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.

Altima Coupe dead as Nissan charts the changes for 2014

The 2014 model year brings plenty of new designs and updates from Nissan - including the next-generation Rogue - but the Altima Coupe has been discontinued. The current generation of the Coupe won buyers over with sharp styling and, at one point, a 270-horsepower naturally aspirated V6 - the heart of the more upscale Infinity G37. It's unlikely that Nissan plans to make another one, but keep in mind the current Coupe was released to the public about a year after the sedan hit dealerships.
The vehicles joining Nissan's lineup for 2014 include the Versa Note hatchback, the NV200 Compact Cargo van and the next-generation Rogue compact SUV. Also new for 2014 is the Pathfinder Hybrid, but that will be added to the lineup in the fall.
Other models that are receiving enhancements are the sedan version of the Altima, which now comes standard with the CVT transmission and gets revised option packs; the Frontier, which gets updated option packs, enhanced navigation system functionality and a sliding middle rear window; the GT-R, which receives a bunch of small performance enhancements and, more importantly, initially will be offered in three versions (Premium, Black Edition and Track Edition), with another, limited special-edition model coming late in the year; the Versa sedan, all versions of which get 60/40-split fold-down rear seats and revised steering and suspension tuning; and last, but not least, the 370Z NISMO will have exterior accent color updates and a new steering wheel and tachometer.

Nissan Patrol attempts Guinness record with 170-ton cargo plane tow

Yesterday, Nissan teased us with a video showing a Patrol pulling up to a 170-ton cargo plane at an airport in the Middle East - we could only assume that the not-for-America sports utility vehicle would attempt to tow the jet.
Well, somebody leaked the official Nissan video, which indeed shows the Patrol successfully pulling the plane 30 meters for what reportedly is a Guinness world record. While Guinness hasn't confirmed the record on its website at time of writing, the 170-ton jet would be the heaviest plane ever towed by a production automobile. The video was taken down quickly, but another video shot by an observer at the event was posted for our enjoyment. We figured Nissan would move to repost the official video sooner rather than later, and it did.
The Patrol seems to have no problem towing 340,000 pounds, but let's just say it wasn't a quick ordeal. Check out the official and unofficial video of the tow below, as well as Nissan's teaser video. In a reversal of fortunes, we also threw in another, somewhat smaller but perhaps just as impressive vid, just for fun.
