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.

Nissan rowed the Note ashore [w/video]

Normally we wouldn't suggest trying to float your car on water, but Nissan has made some modifications to turn its new Versa Note hatchback into a makeshift rowing shell.
Nissan replaced the car's rear seats with a sliding rear rowing seat, modified the doors to open wider at 90 degrees and fitted a pair of oars. Most importantly, they put the whole thing on a floating platform to keep it from sinking into Eton Dorney Lake, the site of the 2012 Olympic rowing competitions in England (where the car is simply known as the Nissan Note).
Then they invited medal-winning competitive rowers Helen Glover, Sophie Hosking and Polly Swann to come along and row the thing, making use of the around-view monitor system to see where they were going. All in all it may not be quite as cool as the boats which Fiat made out of the 500 or Mini made out of its convertible, but it's still enough to float our boat. Check it out in the video clip and press release below and the image gallery above.

Japan prosecutors seek 2 years in prison for ex-Nissan exec Greg Kelly

TOKYO — Japanese prosecutors demanded two years in prison for former Nissan executive Greg Kelly and accused him of joining a “conspiracy” to pay his former boss Carlos Ghosn illicitly in closing arguments Wednesday in a yearlong trial. “That unpaid compensation existed is clear,” prosecutor Yukio Kawasaki told the Tokyo District Court, reading briskly from a thick document. Kelly, a 30-year veteran at the Japanese automaker, was living in the U.S. when he was arrested in November 2018 upon returning to Japan to attend a meeting. The first American to be appointed to NissanÂ’s board, Kelly says he is innocent. He sat calmly in the courtroom, wearing his usual red tie and dark suit, alongside defense lawyers. Everyone in the courthouse was wearing a mask because of the pandemic. Kelly told The Associated Press in an interview last month he did not know all the details of GhosnÂ’s pay. He was determined to retain Ghosn, Nissan's former chairman, because of his extraordinary management skills and wanted to pay him in a legal way, he said. Ghosn was arrested at the same time as Kelly and also maintains he is innocent. He skipped bail in late 2019 and fled to Lebanon, the country of his ancestry. It has no extradition treaty with Japan. The charges center around a pay cut of about 1 billion yen ($10 million) a year that Ghosn voluntarily started taking from 2010, halving his pay after disclosure of high executive pay became mandatory in Japan. Nissan Motor officials considered various ways to make up for the money Ghosn gave up, such as paying him consulting fees after retirement. They also mulled other methods such as payments through subsidiaries and stock options. Nothing had been paid at the time of the arrests. The contention is over whether that money should have been reported as compensation as a de facto promised sum under a binding contract, or didnÂ’t need to be disclosed until it was finalized. Ghosn has said a group at Nissan engineered his arrest because they feared that French automaker Renault, which owns 43% of Nissan, would gain more control over the company. Other Nissan officials made similar comments during KellyÂ’s trial. Renault sent Ghosn to Nissan in 1999 to lead its rescue from the brink of bankruptcy. He successfully steered the maker of the Leaf electric car and Infiniti luxury models for nearly two decades.
