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.

Datsun expands low-cost revival with new Mi-Do in Moscow [w/video]

Those who were disappointed when Datsun changed its name to Nissan over three decades ago may have been pleased to see the marque revived last year, even as a budget brand. Nissan's counterpart to its ally Renault's Dacia budget brand, Datsun has been steadily expanding its lineup of low-cost transportation for developing markets with the debut of the Go hatchback in India, the Go+ minivan in Indonesia and the On-Do sedan in Russia. And now it has returned to Moscow to reveal its fourth model, the Mi-Do.
Based closely on the On-Do sedan (which itself is based on the Lada Granta) the Mi-Do takes on a five-door hatchback bodystyle but with no more frills. It uses the same front-drive chassis with the same wheelbase as the sedan, but its chopped tail makes it a good foot and a half shorter overall. Into that compact shape, Datsun has fitted dual airbags, ABS and... well, that's about it. It's got a 1.6-liter, eight-valve inline-four kicking out a grand total of 87 horsepower to either a five-speed manual or a four-speed automatic. Bare bones, this is.
While delivery of the first On-Do sedans commences next month (with the first example going to an IT specialist in Omsk), the Mi-Do is set to begin delivery early next year. Scope out the video and press release below from the Mi-Do's reveal at the Moscow Motor Show.

Hurricane Sandy cost automakers 15,000 vehicles, may have ruined up to 200k

Hurricane Sandy was the largest Atlantic storm in US history, and its total economic impact is just now coming into view. According to Automotive News, Toyota, Chrysler, Nissan and Honda are set to scrap around 15,000 new vehicles ruined by the storm. Nissan alone accounts for about 40 percent of those, with 6,000 Nissan and Infiniti models deeded "un-saleable" due to damage. The company saw 56 dealerships shuttered due to the storm, but 51 of those have since reopened.
Toyota, meanwhile, had some 4,000 vehicles at its Newark port facility, and of those, 3,000 may be scrapped. An additional 825 were dealer inventory when they were ruined. Honda and Acura dealers are reportedly sending 3,440 vehicles to the salvage yard. By comparison, Chrysler weathered the storm fairly well with 825 units destroyed, while Hyundai suffered only 400 lost units and Kia scrapped around 200.
As you may recall, Fisker also suffered some losses, and Automotive News reports the manufacturer saw 320 Karma models damaged beyond repair. Ford and General Motors have yet to come up with estimates, and no automaker has commented on the full cost of replacing the vehicles.
