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.

'Car Wars' says Ford, Honda to pick up share, Fiat-Chrysler ambitions downplayed

Don't look for a tremendous shifts in automotive market share over the next three years because it might not be coming. That's at least according to the annual Car Wars report by John Murphy, from Bank of America Merrill Lynch Global Research.
In the report's analysis of automakers' market share from 2013 to 2017, it predicts only small changes among the major companies. Ford and Honda see the biggest positive effect with an estimated 0.5 percent increase in their shares over the next three years; to 16.2 percent and 10.3 percent respectively. On the flip side, European automakers and Nissan are expected to lose 0.2 percent each to fall to 8.3 percent and 7.8 percent each respectively. The rest of the industry is predicted to hold steady as it is now.
The biggest loser in that prediction might be Fiat-Chrysler Automobiles. The report certainly throws a wet blanket on its plan for significant gains in market share. Murphy told The Detroit News that the company's goal was "almost unattainable."

2014 Nissan Juke Nismo RS amps up the funky crossover

Nissan unveiled an even hotter version of the hotter Juke Nismo at the Los Angeles Auto Show - the Juke Nismo RS, a 215-horsepower crossover that may be the most hardcore model in the compact CUV segment (until we can convince Mazda to build a Mazdaspeed CX-5, that is).
The 215 hp and 210 pound-feet of torque represent bumps of 18 hp and 26 lb-ft over the standard Juke Nismo thanks to a revised ECU, a new exhaust with a larger diameter tube, and stronger connecting rods. This amped-up engine can be mated to the owner's choice of a six-speed manual, which takes advantage of a stronger clutch cover and dual-mass flywheel, or an Xtronic continuously variable transmission (although the CVT model loses four horsepower and all of the extra torque that the Nismo RS enjoys).
"We expect drivers to feel a noticeable increase in acceleration - especially the manual transmission model - in the RS versus the regular Juke Nismo. It also holds peak torque longer. Combined with the Helical Limited-Slip Differential, which helps reduce torque steer, the sense of driving excitement is unmatched in the Juke lineup," said Pierre Loing, Nissan's vice president of product and advanced planning and strategy.
