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.

2014 Nissan Frontier Diesel Mule [w/poll]

Last August, Nissan shook the truck world when it officially announced plans to source a diesel option from Cummins for its long-overdue Titan replacement, its full-size pickup that's slated to drop this January at the Detroit Auto Show. The 5.0-liter V8 turbodiesel is expected to make somewhere around 300 horsepower and north of 500 pound-feet of torque. This combination of an all-new truck with this new powerplant promises to dramatically change the competitive landscape, splitting the difference between the heavy-duty goliaths from the Detroit Three and the Ram 1500 Ecodiesel. And the intrigue moved a step further when the Frontier Diesel Runner Concept showed up at February's Chicago Auto Show, as it displayed a growing relationship between Nissan and Cummins in a very interesting potential future product.
That concept would melt its clear acrylic hood if the engine ran too long, but this month, we got a chance to test drive a production mule, an otherwise normal Frontier with a Cummins 2.8-liter diesel four-pot under the hood and a ZF eight-speed automatic changing gears. The powertrain figures to be a direct competitor to the 2.8-liter Duramax promised for General Motors' Chevrolet Colorado and GMC Canyon twins, but will Nissan build it? All signs point to probably. Officially, Nissan is taking no position on the future of this program, but a concept followed by putting journalists into a test mule suggests the company is considering the option very seriously. Here's what we gleaned from a brief drive around the posh suburbs of Nashville:
Before we get too deep into this Quick Spin, realize this Frontier is absolutely a mule, not a prototype. More or less cobbled together with duct tape and baling wire, it's not meant to be representative of a finished product, or even a started product. The transmission and shifter is straight out of a Chrysler 300 and the shifter surround is cut out of a panel of plastic. The "Low Sulfur Diesel Only" sticker is, well, just stuck on. We're looking at a "What if?" mockup.

Recharge Wrap-up: Tesla will sell Model S on Alibaba in China, Wrightspeed electrifies garbage trucks

Tesla will sell cars in China using Alibaba's Tmall website. Customers will be able to use the Chinese shopping site to place an $8,200 deposit toward a Model S. Tmall will feature 18 preconfigured versions for customers to choose from, which won't offer quite the level of customization as Tesla's US site. Bloomberg's Jamie Butters calls it a "defensive move" on Tesla's part, and still expects the company to sell cars in China the traditional way. Watch the video at Bloomberg or read more at Bidness Etc. Tesla co-founder Ian Wright's company Wrightspeed is converting garbage trucks to EVs. The same brand that created the exciting X1 EV is making trash collection much cleaner. "Garbage trucks are the perfect driving cycle for us: they get two or three miles per gallon, drive 130 miles a day with 1,000 hard stops that chew on the brakes," says Wright. The system puts an electric motor at each of the truck's drive wheels, and includes an on-board generator that runs on diesel or natural gas to extend driving range. Read more at Xconomy. British company Hillside Leisure is converting the Nissan e-NV200 into a camper van. The electric RV, called the DalburyE, debuted at the UK's Motorhome and Caravan Show in Birmingham. It sleeps up to four people, and features a pop-up roof, a gas stove, fridge, sink and other amenities. It's a great way to take full advantage of an RV park's electrical outlet to charge the van while camping in it. Read more at Transport Evolved, and see more photos at Hillside Liesure's blog.
