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.

Recharge Wrap-up: Aoxin Ibis could be Tesla competitor in China, Nissan Qashqai ZEOD due this year

Zero Motorcycles is expanding its North American dealer network. With more retailers selling the electric motorcycles, Zero has added three new regional sales directors. "We are enjoying a great response to our 2015 line of motorcycles and accessories, and it's driving accelerated growth," says Zero's Mike Cunningham. "To support and sustain this momentum, we are investing in a bigger, stronger team and partnering with leading motorcycle retailers." More sellers are getting on board as electric motorcycles appear more and more viable, and they're finding it's bringing in a new set of enthusiastic customers. Zero recently revamped its production process to meet the expected increase in demand for 2015. Read more in the press release, below. Chinese automaker Aoxin New Energy, has built an electric car that is set to compete with the Tesla Model S. The aluminum and carbon fiber Aaoxin Ibis (pictured) is longer than the Model S, but weighs less than the Tesla at 4,034 pounds. It offers 181 horsepower and has a top speed of only 94 miles per hour, but it boasts a driving range of about 285 miles per charge. Its upscale interior borrows its looks from the Tesla, with its digital gauges and large, central touchscreen. Read more at Car News China, or at Green Car Reports. Nissan will likely debut a Qashqai ZEOD concept later this year. The plug-in hybrid version of the compact crossover borrows its ZEOD moniker - which stands for Zero Emissions On Demand - from Nissan's hybrid Le Mans racer. It's possible it will borrow its powertrain technology from the Renault Eolab Concept, which could mean a 1.0-liter engine paired with an electric motor. Based on the success of the Qashqai in Europe, it's not unlikely that the plug-in version will debut there (Green Car Reports is betting on Frankfurt). Read more at Green Car Reports. Zero Motorcycles Expands North American Network Strong Demand Fuels Double-Digit Dealer Growth and Additions to Sales Team SANTA CRUZ, Calif., March 11, 2015 /PRNewswire/ -- Zero Motorcycles, the global leader in the electric motorcycle industry, announced today that three new regional sales directors have been added to the company's roster in the first quarter of 2015. The expansion of the sales team comes in response to rapid growth within the dealer network and reflects Zero's commitment to delivering world-class products and service.

Cadillac ELR, Nissan Resonance and Ford Atlas win Eyes on Design awards

This year's annual Eyes on Design awards were presented at the end of press days for the Detroit Auto Show on Tuesday. Given out for the best production and concept car designs that debuted at the show, and voted on by an esteemed panel of actual car designers, this year's award for best production vehicle design went to the 2014 Cadillac ELR. The 2014 Chevrolet Corvette, which was the show favorite among Autoblog editors, apparently did not impress the Eyes on Design judges enough with its all-new vent-festooned design.
The award for best concept design was actually split as a tie among the Nissan Resonance and Ford Atlas concepts. Last year's winners were the 2013 Ford Fusion and the Lexus LF-LC concept.
The Eyes on Design organization also presented a new honor this year called the Catalyst Award to Bob Lutz, former Vice Chairman of General Motors. Lutz is reported to have given a defense of design in his acceptance speech, arguing that advancements in quality across the industry as a whole have made good design a key differentiator for buyers.
