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.

2016 Nissan Titan further teased ahead of Detroit debut

Nissan is less than a week away from finally unveiling the 2016 Titan at the 2015 Detroit Auto Show on January 12 after months of teasing. Unfortunately, the latest video in Nissan's Truckumentary series about the Titan's engineering comes off a bit dull. It mostly focuses on the trucks American heritage rather than on its capabilities. However, the clip does drop a few hints about the 5.0-liter Cummins diesel V8. The company not only wants to keep fuel economy high but also focus on giving drivers a deep well of power that's ready at any time. The engine is rumored to offer over 300 horsepower and about 550 pound-feet of torque. The best part of this video's release is the accompanying gallery (below) showing the test truck from practically every angle. It's still covered in camouflage, but the front grille appears much more upright compared to previous spy shots. A final interesting tidbit comes in the text at the very end of the clip where Nissan reveals the Titan isn't expected to go on sale until late 2015.

Bret Michaels Poisons Nissan's commercial trucking ops

Mötley Crüe isn't the only 1980s hair-metal band getting into the world of auto promotion. Poison frontman and reality show star Bret Michaels is following their lead and doing some advertising of his own. Where the Crüe have been all over the airwaves in recent years with a Super Bowl ad for Kia and music licensing with Dodge, Michaels has taken a very different route by becoming the pitchman for Nissan Commercial Vehicles.
The videos run the gamut to advertise predominantly the NV line of full-size vans, but the NV200 shows up a few times too. The star of this new campaign is Michaels' full-length music video (above) for the song Tough Love. It's basically a parody of all of those '80s rock ballads where the bands would slow the tempo down a little and reveal their softer side. Michaels rocks out at the Nissan proving grounds in Stanfield, AZ, while showing off the evaluation process and strutting around like a proper rock frontman. There are also a bunch of shorter videos (below) with the singer highlighting each part of the vans' torture testing. Although, the dialogue in these come off a bit more stilted. With these '80s metal bands getting into advertising, can it be long before Warrant is shilling for Fiat or Ratt for Mazda?
