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 invests in sailing ships to reduce its carbon footprint

Renault is taking a page from the golden age of sailing as the company looks towards reducing its carbon footprint through the use of cargo sailing ships. The French automaker recently announced its partnership with Neoline, a start-up enterprise based in the west of France. The firm specializes in reducing the cost and emissions of typical cargo ships, by reintroducing sailing into the transportation equation. Renault's goal is to reduce its global carbon footprint by 25 percent in 2022, as compared to where they were in 2010. This plan also includes a separate target, to lower supply chain emissions - which includes shipping methods such as trucks, trains, and cargo ships - by 6 percent, compared to levels in 2016. Two prototype cargo vessels, complete with a full set of sails, will be introduced by 2021-22. These two ships will travel between the U.S. eastern seaboard (exact locations are TBD) and the French port cities of Saint-Nazaire and Saint-Pierre & Miquelon. Specifics about what exactly the ships will be carrying has not been released, though Renault is part of an extensive global auto alliance that includes Nissan and Mitsubishi. "For nearly 10 years, we have been working to identify the most environmentally sustainable solutions," said Jean-Francois Salles, Alliance global director, production control. "For example, optimizing the fill rates of the containers and trucks, producing eco-friendly packaging, and implementing a multi-modal system." The current demonstration vessel measures in at 446 feet in total length and has more than 45,000 square-feet of sail. For all you big ship fans out there, the Titanic was about double this size, stretching about 882-feet in length. When powered solely by the wind, Neoline CEO, Jean Zanuttini, says that total emissions drop by as much as 90 percent, versus the carbon footprint of a traditional cargo vessel.

2013 Nissan Pathfinder: January 2013

We've now had our long-term 2013 Nissan Pathfinder for about a month, and some impressions are starting to solidify, while others remain contentious among the team. Most notable among those contentious items is our Pathfinder's paint color, which was chosen by vote among the Autoblog team.
Dubbed Mocha Stone, it beat out Cayenne Red by a single vote. I was a Mocha Stone supporter and like it even more in person than on Nissan's configurator. It's a mature choice that can be comfortably placed in the grouping of silver, white and gray tones buyers routinely choose most often over all the colors of the rainbow offered on cars these days for the sake of attention. Staunch opponents of Mocha Stone on the team remain unswayed. Democracy is a difficult process, people.
