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.

Weekly Recap: Chevy and Alfa plot comeback strategies

Chevrolet and Alfa Romeo were two of the 20th Century's most iconic automotive brands. Chevy embodied America's post-war power and confidence. Alfa was the definition of the stylish Italian sports car. They reached halcyon heights in the 1950s and '60s, before declining precipitously amid new competition, changing consumer tastes, and uneven corporate management. Both say 2015 is the start of something better, and this week Chevy and Alfa laid out ambitious plans and showcased new cars that they hope will make them more relevant this year, and in the coming years. Each brand sits at its own crossroads, and their paths forward are as different as the Chevy Cruze and the Alfa Romeo Giulia. Chevy is still a sales beast, as evidenced by its volume of 4.8 million vehicles sold around the world last year. Chevy executives are fond of saying one of their cars is sold every seven seconds, which illustrates the strength and reach of a car brand that is the fourth largest in the world. "Make no mistake about it, we are a brand for the people," said General Motors North America president Alan Batey. But he wants consumers to want to buy a Chevy for its design and technology, not simply because it's affordable. That starts with all Chevys now featuring a distinctive a family look, with sporty cues from the Corvette or strong lines that riff on the Silverado pickup. "We want people to fall in lust with our cars," said Mike Pevovar, executive design director for Chevy passenger cars. "That initial emotional attraction has to be right on the exterior, and that's where form comes into play." Chevy is also loading up its cars, like the freshly unveiled 2016 Chevy Cruze, with technology to appeal to a younger crowd that prizes connectivity. The Cruze will offer Apple CarPlay and Android Auto with its MyLink infotainment system, and OnStar with 4G LTE and wifi. Seeking out younger buyers is also sound business practice: Millennials now outnumber Baby Boomers as the largest single age group in the United States. Younger buyers also can improve a brand's image, which is another area where Chevy would like to improve. Chevy ranks 82nd on Interbrand's Best Global Brand's list, behind 11 other automakers. Apple is No. 1. "We need our own variation of the Genius Bar," Batey said. 2016 Alfa Romeo Giulia View 3 Photos Meanwhile, Alfa is in different shape.

Nissan's Carlos Ghosn reportedly arrested, to be fired for financial misconduct

TOKYO — Nissan Motor Co said it was ousting Chairman Carlos Ghosn for alleged financial misconduct and Japanese media reported he been arrested, a shocking fate for a leader hailed for rescuing the company from close to bankruptcy. The Japanese automaker said Ghosn's alleged misconduct included personal use of company money and under-reporting how much he had been paid. Ghosn is also chairman and chief executive of Nissan's French partner Renault and one of the best-known figures in the global car industry, and his departure would raise question about the future of the alliance. Nissan said it launched an months-long investigation after a whistleblower tipped it off to wrongdoing by Ghosn and Representative Director Greg Kelly. "The investigation showed that over many years both Ghosn and Kelly have been reporting compensation amounts in the Tokyo Stock Exchange securities report that were less than the actual amount, in order to reduce the disclosed amount of Carlos Ghosn's compensation," Nissan said in a statement. It said CEO Hiroto Saikawa would propose that the Nissan board remove Ghosn and Kelly. Neither Ghosn nor Kelly could be reached for comment. Renault shares tumbled 11 percent in Paris to be among the worst performing stocks in Europe. Nissan's German-listed securities plunged 10 percent. French President Emmanuel Macron said the government, the French carmaker's top shareholder, will be vigilant about Renault and its alliance with Nissan. Cost cutter Known as "Le Cost Killer," Ghosn is credited for reviving the Japanese automaker and has remained popular despite the massive job cuts that he brought and recent controversy over his lucrative pay package. Japanese media reported that Ghosn had reported around 10 billion yen worth of compensation as around 5 billion yen. Ousting Ghosn, 64, is bound to raise questions about an alliance that he personally shaped and had pledged to consolidate with a deeper tie-up, before eventually stepping back from its operational leadership. "The initial share price reaction shows how pivotal he is," Citi analyst Raghav Gupta-Chaudhary said on Monday. The current alliance structure has long undervalued Nissan shares held indirectly by Renault investors, he added. "Ghosn is viewed as critical for value unlock." Renault owns 43.4 percent of Nissan, while Nissan owns 15 percent of Renault, with no voting rights in a partnership that began in 1999.
