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.

Angry Nissan Leaf Driver may make 'Rolling Coal' illegal in New Jersey

It's always a few bad apples who ruin polluting just for fun for the rest of us. That time-honored American tradition of being rude for laughs, otherwise known as 'rolling coal,' might become illegal in New Jersey, if a Nissan Leaf-driving politician gets his way. The politician in question is State Assemblyman Tim Eustace (D-Bergen), who was purposefully hit by a blast of dark smoke recently while driving his Leaf on the New Jersey Turnpike, according to NJ.com. This personal experience of what he called "just youthful ignorance" is encouraging him to submit a bill (A3583), which, "Prohibits retrofitting diesel-powered vehicles to increase particulate emissions for the purpose of 'coal rolling'; prohibits the practice of 'coal rolling.'" If you're caught violating the law, you would be hit with a fine from the state Department of Environmental Protection. Of course, the Feds say it is already illegal to modify an exhaust system in a way that allows coal rolling. Rolling coal has become a bit of a meme recently, with videos of laughing truck drivers spewing their modified exhaust pipes at green cars, pedestrians and bikers around the country. Eustace told NJ.com that, "People had been telling this has been going on, but I hadn't seen it. I was surprised to experience it myself." Perhaps a coal roller in New Jersey will be surprised, too, when the first big fine hits. News Source: NJ.comImage Credit: YouTube Green Nissan Green Culture Diesel Vehicles rolling coal

Nissan to expand next-gen Titan with more engines, configurations

Not much has changed with the Nissan Titan in the decade that it's been on the market, but the 2015 model year could move the needle enough to turn the truck from an "also ran" in the fullsize truck market to more of a contender. Edmunds had the chance to sit down with Pierre Loing, vice president of product and advanced planning and strategy for Nissan North America, who indicated that not only will a new truck be coming for 2015, it is also expected to take a bigger chunk of the truck market currently dominated by Ford and General Motors.
For starters, the article quotes Loing saying that the next-gen Titan could sell 100,000 units, which is almost five times the number of Titans and the same number of Toyota Tundra trucks sold last year. To accomplish this, Nissan is planning to offer a wider number of models (including a regular cab version) and more powertrain options; we're sure this means Nissan is considering offering a V6. The addition of a regular-cab, V6 Titan would also allow this truck to be more competitively priced.
Will that be enough to attract buyers away from the Big Three domestic trucks? We'll just have to wait and see...
