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.

Nismo mashes it up with Sentra 370Z and Altima GT-R

Nismo was a tuning division once content (or required) to restrict itself to just one or two models at a time, but these days Nissan is taking the gloves off and allowing its motorsport department to tune just about everything's it's got.
Now in its thirtieth year, Nismo tunes versions of the GT-R, 370Z, Juke and Versa Note, and will soon be working its magic on the Sentra and European-market Qashqai and Pulsar. And that's not even taking into account its considerable racing programs. At this rate, Nismo is going to run out of vehicles to tune pretty quickly, so what has it done? Invent new ones!
No, we're afraid that Nissan is not letting its Nismo division produce its own stand-alone product, but it has released two sets of amusing renderings combining two vehicles into one. One depicts a GT-R crossed with a Teana sedan (better known in these parts at the Altima), while the other crosses a Sentra with a 370Z.

Nissan confirms what's in the box

While there were few doubts about what could've been hiding under the giant cardboard box being transported on a flatbed truck earlier this month, Nissan has officially confirmed that it was, in fact, a Versa Note being delivered from Amazon.
As a part of the special promotion, online shoppers who bought a Versa Note using the retailing giant also received a $1,000 Amazon gift card. Scroll down to watch how the car was packaged and shipped as well as what the buyer did with all that cardboard.
