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.

Demand for electric car rentals unplugged by range anxiety

It's the hurdle that electric vehicles must clear to be launched into the mainstream: range anxiety. But this time it isn't prospective customers who worry about running out of juice, Bloomberg reports, but renters who return to car rental agencies before their lease is up and trade their EVs in for more traditional gasoline-powered autos and gas-electric hybrids.
"People are very keen to try [electric vehicles], but they will switch out of the contract part way through ... they think they can't get to a charging station," says Lee Broughton, head of sustainability at Enterprise. Enterprise customers who rent EVs reportedly trade them in 1.6 days into the rental period on average, which compares unfavorably to the six- to seven-day rental periods of traditional, fuel-burning automobiles.
Christopher Agnew, an analyst at MKM Holdings LLC, says that longer range would help rental customers' range anxiety, especially since they are usually renting vehicles in unfamiliar places.

Forza Horizon G-Shock Car Pack brings Nissan IDx, Subaru Brat [w/video]

With winter's icy grip around much of the nation, now may be the perfect time to sit inside at night and enjoy some video games. The latest six-car G-Shock pack for Forza Horizon 2 on the Xbox One is now here, and it gives players a very eclectic group of vehicles to race around the game's open world. This month's group of vehicles spans the decades ranging from 2015 back to 1953. The newest and only concept of the group is the 2015 Nissan IDX Nismo. Since the production chances for this retro coupe look increasingly slim, this game might be your only chance to get behind the concept's wheel. However, if you prefer driving something a bit more classic and Italian, the 1953 Ferrari 500 Mondial is available. To add one more flavor of performance, there is the 2010 Mazda Mazdasped 3 hot hatch, which is also this month's free car for download. In addition to three takes on the sports car, Turn 10 is also offering a trio of off-roaders. The quirkiest among them is the 1980 Subaru Brat GL, which features two jump seats in the back to avoid the dreaded chicken tax. If you prefer something more boxy and American, then the 1975 Ford Bronco is sure to please. Finally, for some real power to get through the mud, there's the 2013 Ford F-150 SVT Raptor as tuned by Shelby with a supercharged 6.2-liter V8 making 575 horsepower. As usual, the whole pack costs players $5 to download, or it's free as part of the season pass. Scroll down for a brief video showing all of these virtual rides off and read the press release about them from Turn 10 Studios. This content is hosted by a third party.
