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.

Club to restore amazeballs Datsun Safari Rally Z

Thanks to the Nissan Restoration Club, a legendary rally car is coming back to life. At the recent Nissan 360 media event, the Japanese automaker announced that its restoration club is bringing the Safari Rally Z back to original running condition. A variant of the Fairlady Z (or Datsun 240Z in the US), the Safari Rally Z has a fastback coupe body and a 215-horsepower inline-six engine. It won East African Safari Rally championships in both 1971 and 1973. The restoration is scheduled for completion this December.
Formed in 2006, Nissan's Restoration Club is comprised of 60 volunteer members who are passionate about Nissan's historic racecars. The club's past restoration projects include the 1964 Skyline racecar and 1947 Tama electric vehicle. Read the press release below for all the details on the latest restoration, and check out the gallery for photos of the Safari Rally Z as well as the 1972 Fairlady 240Z.

UAW calls on US State Department to help with Nissan plant

The United Auto Workers is calling for reinforcements in its ongoing battle with Nissan at the manufacturer's Canton, MS factory, where the Altima, Armada, Titan and NV (and eventually, the next Murano) are built. The union has been attempting to organize the employees at the factory for several years, but it's been largely unsuccessful.
Now, Reuters is reporting that the UAW is teaming with the IndustriALL Global Union and requesting intervention by the US State Department, with both groups accusing Nissan of using "threats, intimidation and fear" to keep the 5,600 workers at the facility from organizing. The two unions say this violates the guidelines of the Organization for Economic Cooperation and Development, an international organization dedicated to stimulating economic growth.
The UAW and IndustriALL are asking the State Department's National Contact Point to serve as mediator with Nissan, to make sure things play out fairly. Speaking to Reuters, though, there's at least one Michigan-based labor adviser that's skeptical of the move.
