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.

2016 Nissan Titan coming to 2015 Detroit Auto Show

The Titan has continued to sit in a corner of Nissan's front yard, taken out on occasion but largely unloved, the same way you see a project truck in a neighbor's driveway that makes you wonder, "Are they ever going to do anything with that?" The fullsize pickup made the news about six months ago when reports surfaced that the next generation would offer a Cummins diesel engine that had originally been meant for Ram, then it returned to the shadows.
According to a report from Edmunds, the Titan will return to the spotlight in about a year, with the unveil of the 2016 model planned for next year's Detroit Auto Show. Along with that oil-burner, it will bring a gasoline V6 engine, a complete redesign and a regular cab configuration to finally give it a fighting chance against the thick end of the light-duty truck market. Toyota gets pressed for the molasses-like sales of the Tundra, but that fullsize entrant sold 7,890 units in January and 10,988 in December 2013. Nissan sold 887 Titans in January, 1,284 in December 2013 and broke 2,400 US sales in a single month just once in four years. (The segment-leading Ford F-150, for reference, sold 46,536 units in January.)
An entry-level model and a regular cab option should give the Titan a welcome and overdue sales boost. Better power numbers and fuel economy for the V8 would probably go a long way, too. We expect to start getting glimpses of its future later this year.

Nissan looking to expand UK plant to build Infiniti Q30

With the Infiniti Q30 concept heading to the Frankfurt Motor Show next month and a future premium compact model heading into production at Nissan's Sunderland UK assembly plant, just connecting the dots tells us this new small Infiniti is headed for UK production. Backing this up, Reuters is reporting that Nissan is looking to expand the Sunderland plant by 25,000 square feet, while Automotive News Europe takes it a step further by almost confirming that the Q30 will be built alongside the Nissan Qashqai and Note.
The reports say that Sunderland is already the UK's biggest automotive plant, but the expansion will make it even larger with production capacity expected to rise from the current 500,000 units built each year to more than 550,000. There is no indication if the expansion will bring more jobs to the plant, which already employs around 6,000 people.
