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.

Renault names new leaders as jailed Carlos Ghosn bows out

PARIS — Renault appointed Michelin boss Jean-Dominique Senard as its new chairman on Thursday, after Carlos Ghosn was forced to resign in the wake of a financial scandal that has rocked the French carmaker and its alliance with Japan's Nissan. Senard will become chairman immediately, the company said, with deputy chief executive Thierry Bollore taking over Ghosn's other Renault role as full CEO. The appointments may begin to ease a Renault-Nissan leadership crisis that erupted after Ghosn's Nov. 19 arrest in Japan and swift dismissal as Nissan chairman. Senard, 65, now faces the task of soothing relations with Renault's Japanese partner and resuming talks on a new alliance structure to cement the 20-year-old partnership. "It's important that this alliance remain extremely strong," Senard told reporters after a board meeting - citing the mounting investment demands of new vehicle technologies. "It is our compulsory duty to go forward together." Ghosn's exit also marks a clear end to one of the auto industry's most feted careers, two decades after he was despatched by former Renault boss Louis Schweitzer to rescue newly acquired Nissan from near-bankruptcy — a feat he pulled off in two years. After 14 years as Renault CEO and a decade as chairman, Ghosn formally resigned from both roles on the eve of the board meeting. Ghosn's arrest and indictment for financial misconduct has strained the Renault-Nissan relationship, threatening the future of the industrial partnership he transformed into a global carmaking giant over two decades. For two months, the tensions deepened as Renault and the French government stuck by Ghosn despite the revelation he had arranged to be paid tens of millions of dollars in additional income, unbeknownst to shareholders. Ghosn has been charged with failing to disclose more than $80 million in additional compensation for 2010-18 that he had agreed to be paid later. Nissan director Greg Kelly and the Japanese company itself have also been indicted. Both men deny the deferred pay was illegal or required disclosure, while not contesting the agreements' existence. Ghosn has denied a separate breach of trust charge over personal investment losses he temporarily transferred to Nissan in 2008. Ghosn had agreed in recent days to step down from Renault, Reuters reported on Tuesday — but only after the French government, Renault's biggest shareholder, called for leadership change and his bail requests were rejected.

Nissan's Le Mans-bound ZEOD RC electric racecar nearing completion [w/video]

Nissan is working away on its ZEOD RC (Zero Emission On Demand Racing Car) which is still on pace for a Le Mans arrival in 2014. As of right now, the DeltaWing-shaped car's carbon-fiber tub and chassis have been completed. The next step will be installing the twin electric motors and fitting the seat of driver and GT Academy winner Lucas Ordóñez. If the current schedule sticks, the zero-emissions racer will hit a UK track for test laps in September.
But while those initial shakedown laps will be under full electric power, it's unclear whether the setup fielded in the UK will survive until Le Mans. Nissan itself says that it will be testing a number of "electrified" drivetrains ahead of the 2014 24 Hours of Le Mans, which is a significant departure from race car design - usually, the teams know what's powering their car before they start building it.
"Just developing a single powertrain option in only 12 months would be a mammoth task but we're looking to carefully examine a number of options to ascertain which will be best suited for Le Mans," said Darren Cox, Nissan's global motorsport director. Take a look below for a video and press release from Nissan documenting the ZEOD RC's build process.
