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.

Ghosn's first jail interview: I was the victim of 'plot and treason'

TOKYO — Carlos Ghosn said Nissan executives opposed to his plans for closer ties with automaking partner Renault SA resorted to "plot and treason" to disrupt them and were behind the financial misconduct allegations against him. Speaking to the Nikkei newspaper in his first media interview since his arrest on Nov. 19, Ghosn said he had discussed plans to integrate the companies with Nissan CEO Hiroto Saikawa in September. But Nissan executives employed "plot and treason" to uproot those plans, Ghosn said. Ghosn, who spearheaded Nissan's turnaround two decades ago, had pushed for a deeper tie-up between Nissan and Renault, including possibly a full merger, despite strong reservations at the Japanese corporation. He remains in detention following his arrest and indictment on charges related to breach of trust and understating his salary. His arrest has clouded the outlook for closer ties between Nissan and Renault, along with Mitsubishi Motors Corp, the third member of the automaking alliance Since his arrest, Saikawa has said it was not the time to discuss revising the partners' complex capital ties. Nissan and Mitsubishi Motors have dismissed Ghosn as chairman, while he has resigned from the helm at Renault. Ghosn denied accusations of improper payments to a company run by a Saudi businessman, saying the payment had been approved by a Nissan executive. Ghosn also called accusations by both Nissan and Mitsubishi that he received nearly 8 million euros in improper payment through a Dutch-based joint venture of the two automakers "a distortion of reality," and argued his luxury residences in Rio de Janeiro and Beirut were approved by Nissan's legal department. Nissan has said it was not aware that it had paid for many of Ghosn's properties. On Wednesday, a spokesman said that the company was unable to comment on Ghosn's legal defense. Ghosn, in the 20-minute interview, denied that his tenure at Nissan had been a "dictatorship." "People translated strong leadership to dictator, to distort reality" for the "purpose of getting rid of me," he said. Ghosn added that his health was fine, and that he wouldn't flee if freed on bail. Meanwhile, NHK reported that Saikawa plans to hold his first face-to-face discussion with new Renault Chairman Jean-Dominique Senard on the sidelines of an alliance meeting in the Netherlands on Thursday.Related Video: This content is hosted by a third party.

Nissan and NASA team up on autonomous zero-emissions test fleet

Nissan and NASA have announced a collaboration on autonomous vehicles that, if we're honest, makes more sense to us than Infiniti partnering with Red Bull. The two are commencing a five-year R&D program to explore autonomous drive systems, human-machine interfaces, network-enabled applications, and software analysis and verification. What's more: the test fleet will be zero emissions and rolling around NASA's Ames Research Center by the end of this year. We will assume that means autonomous Leafs, but Nissan could be working on a new vehicle for the purpose. Nissan CEO Carlos Ghosn said the company will begin offering autonomous features "beginning in 2016," and wants to have commercially available self-piloting vehicles that can "navigate in nearly all situations," including urban environments, by 2020. Who better to assist than the people who put a self-driving rover on a planet that never gets closer than 34 million miles away? What does NASA get out of it? Access to Nissan's materials and component developments, prototyping systems, and robotic software test beds. Sounds like everybody wins. The press release below has more information. Nissan and NASA partner to jointly develop and deploy autonomous drive vehicles by end of year SUNNYVALE, Calif. Jan. 8, 2015 - Nissan Motor Co., through its North American-based organization, and NASA today announced the formation of a five-year research and development partnership to advance autonomous vehicle systems and prepare for commercial application of the technology. Researchers from Nissan's U.S. Silicon Valley Research Center and NASA's Ames Research Center at Moffett Field, Calif., will focus on autonomous drive systems, human-machine interface solutions, network-enabled applications, and software analysis and verification, all involving sophisticated hardware and software used in road and space applications. Researchers from the two organizations will test a fleet of zero-emission autonomous vehicles at Ames to demonstrate proof-of-concept remote operation of autonomous vehicles for the transport of materials, goods, payloads and people. For NASA, these tests parallel the way it operates planetary rovers from a mission control center. The first vehicle of that fleet should be testing at the facility by the end of 2015. "The work of NASA and Nissan – with one directed to space and the other directed to earth, is connected by similar challenges," said Carlos Ghosn, president and CEO of Nissan Motor Co.
