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: Nissan reveals GT-R LM Nismo, NRG plans eVgo expansion

Nissan has officially revealed the GT-R LM Nismo LMP1 car. The hybrid Le Mans racer uses a biturbocharged 3.0-liter V-6 up front to power the front wheels, plus a kinetic energy recovery system for an extra boost. Football fans likely caught a glimpse of the car in Nissan's With Dad commercial that aired during the Super Bowl, but the company has a couple more videos that show the car off quite well provided below. "This is innovation that excites," Says Nismo president Shoichi Miyatani. "Sustainability is at the top of our agenda, and the technical regulations for Le Mans give us the freedom to pursue new ideas in this area." Read more at Green Car Congress, or in the press release below. The NRG eVgo charging network now operates 120 DC fast charging stations in California. 60 of those are "Freedom Stations," offering both CHAdeMO and CCS charging cables, and 52 more of these are in the works. NRG plans to expand the eVgo network to 25 US markets in the next two years (up from the current 10), including chargers in Tennessee, as well as linking cities along the near entirety of the East and West coasts.

As of now, the Supercharger network extends as far north as Edinburgh, southwest to Exeter, and to Maidstone in the southeast, which is just up the road from access to mainland Europe through the English Channel Tunnel. Tesla operates more than 1,600 Superchargers worldwide at over 300 stations, with 129 stations and more than 670 Superchargers in Europe. Read more at Hybrid Cars.

Nissan itself will be indicted alongside Ghosn, report says

Prosecutors in Tokyo are expected to file charges against Nissan itself alongside an expected indictment against former Chairman Carlos Ghosn as part of the ongoing financial misconduct case. That's according to a report from Japan's Nikkei business daily, which does not identify its sources. Charges are also likely against Greg Kelly, a member of Nissan's board of directors who was taken into custody with Ghosn Nov. 19 after Japanese authorities questioned the former chairman aboard a corporate jet at the Tokyo Haneda airport. Monday is the deadline when prosecutors must either indict the two executives, release them or arrest them on new allegations. Both men are accused of under-reporting salaries in five annual reports that stretch through the fiscal year that ended in March 2015. The Nikkei says they'll also be arrested on new allegations of misstating financial information for the subsequent three business years. Nissan would be charged for not preventing the alleged crime. Both men have reportedly denied the allegations. In response to the Nikkei report, a spokesman for Nissan told Automotive News the company had "identified serious misconduct related to the reporting of Mr. Ghosn's compensation" and was cooperating with investors. The turmoil over Ghosn prompted the automaker to scrap plans to unveil a long-awaited longer-range Leaf electric car at the L.A. Auto Show last week. Ghosn is accused of conspiring to understate his income by about half the 10 billion yen (about $88 million) over the period. Reports say the issue relates to deferred compensation that Nissan CEO Hiroto Saikawa reportedly signed off on but may not have understood. The company didn't report the deferred compensation in Japanese securities filings as it is required, since the money is considered a future liability against the company. Automotive News cites an unnamed source who says Nissan has identified some $80 million in unreported deferred compensation promised to Ghosn. Nissan's board voted Nov. 22 to oust him as chairman, and Mitsubishi followed suit days later. Ghosn remains the CEO and chairman of Renault, however. Under Ghosn's guidance, Nissan and Renault joined forces in 1999 when Nissan was teetering toward bankruptcy. Mitsubishi joined on in 2016, with all three members able to jointly develop products and control costs. He had reportedly been pushing for deeper ties, including a possible merger between Nissan and Renault at the urging of the French government.
