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.

Renault taking Alpine endurance racing, enters 24 Hours of Le Mans

Renault isn't letting up with the return of its Alpine brand. After announcing a partnership with Caterham to bring a new Alpine to market by 2015 (now expected by 2016), the French firm has announced it is taking Alpine racing again in the European Le Mans Series this year - and that includes The 24 Hours of Le Mans.
It has been 35 years since Alpine last competed in Le Mans, when it won the race outright and dropped the mic as it left the pits, never to return. Before that, in the 11 years it campaigned in the most famous endurance race on the planet from 1963 to 1978, it took seven class wins.
Caterham won't be involved with the race team, however; that will be an effort spearheaded by the Signatech-Nissan team that has been running GT Academy winners in LMS racing. Alpine is preparing an LMP2 chassis that will get a 500-horsepower Nissan engine for this year's championship, with the first two named drivers being Nelson Panciatici (above right) and Pierre Ragues (above left). The third driver for Le Mans will be announced later this month when the racer is launched at the Le Castellet race track in southern France.

Dacia Duster to spawn inexpensive Nissan Terrano, will we get it?

When going to overseas auto shows, one can't help but spend an inordinate amount of time eyeballing forbidden automotive fruit. It's often of the seriously rare, criminally powerful and six- or seven-digit variety. But more often than one might think, the genuinely affordable overseas hero makes us swoon, too. So it is with the Dacia/Renault Duster, the cheap-as-chips, hard-wearing utility vehicle. We've often thought that its basic, rugged charms would play well in the US if saddled with a low enough price tag, but we've never seen much of a window for that to actually come true.
But now, Autocar India is reporting that Nissan will flex its alliance with Renault to spin off a Duster of its own, one that exhumes the Terrano nameplate, a moniker once used for overseas versions of the first- and second-generation Pathfinder. The new model will feature unique sheetmetal to give it a familial look, but the interior will be the same, and we expect the same goes for the powertrain, meaning there will be a range of gasoline and diesel four-cylinder engines with both manual and automatic gearboxes and front- or all-wheel drive.
So, does that mean we'll get a Nissan version of the Duster-based Terrano to call our own? Sadly, almost certainly not. Company spokesman Dan Bedore tells Autoblog flatly, "There are no plans to bring this model to the US." Bummer. Even if it isn't ultimately as capable as the larger, long-in-the-tooth Xterra (it's more on par with the now departed Canadian-market X-Trail), we think the Duster's archetypal SUV looks and low cost barrier would win it plenty of fans in our market. Our guess is that redesigning the model to meet US regulations (crash, emissions, lighting, etc.) would be prohibitively expensive, and the Dacia/Renault model is built in some pretty distant facilities - Brazil, India, Romania and Russia among them - making the business case harder still.
