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.

Carlos Ghosn re-arrested and thrown back in jail [UPDATE]

TOKYO — Tokyo prosecutors arrested Nissan's former chairman Carlos Ghosn on Thursday for a fourth time, on fresh allegations that cut short his brief time outside detention. Early in the morning, Ghosn was taken from his apartment in Tokyo to the prosecutors' office and then sent to the Tokyo Detention Center, the same facility where he spent more than three months following his arrest in November. He had been released on bail just a month earlier. It's unclear how long Ghosn may be detained under the latest arrest, which involves what prosecutors said was a new alleged crime. "My arrest this morning is outrageous and arbitrary," Ghosn said in a statement issued Thursday. "It is part of another attempt by some individuals at Nissan to silence me by misleading the prosecutors. Why arrest me except to try to break me? I will not be broken. I am innocent of the groundless charges and accusations against me." The prosecutors defended the move, saying the latest allegations are a new case requiring precautions to prevent Ghosn from destroying evidence. They allege $5 million in funds sent by a Nissan subsidiary to an overseas dealership were diverted to a company controlled by Ghosn. "We now have a totally different case, and we are only doing what we think is right," Shin Kukimoto, deputy chief prosecutor at the Tokyo District Prosecutor's Office, told reporters. "As a result of our investigation, we have a new case in which he must be detained, and we have appropriately obtained an arrest warrant from the court," he said. Ghosn, 65, was first arrested on Nov. 19 on charges of under-reporting his compensation. He was rearrested twice in December, including on breach of trust charges. The multiple arrests prolong detentions without trial and are an oft-criticized prosecution tactic in Japan's criminal justice system. The allegations in the most recent arrest cover three money transfers from 2015 through last year, according to the prosecutors. Kukimoto said the new allegation of breach of trust is different from an earlier charge made in January. The companies where the money was transferred to, the motives, and the alleged scheme are all different, he said. He refused to identify the three companies allegedly involved but said one company was in effect owned by Ghosn. Unlike an earlier case, in which Ghosn caused damage to Nissan to benefit himself and a business partner, this time it was merely "for his own personal benefit," Kukimoto said.

Nissan Cube dead for 2015

Another class cut-up has graduated from our motor pool. The Nissan Cube's indefatigable weirdness was likely both its chief selling point and its Achilles Heel, but Autoblog sources say that after a six-year run in the US, the niche player has been scrubbed from the Japanese automaker's lineup.
The move is hardly unexpected - there was confirmation from Nissan Canada that it was pulling the plug on the asymmetric little front-driver in its market back in May, and sales have not exactly been sparkling here in the States, either. In June, Nissan shifted just 336 Cubes, down 23.8 percent year over year. So far this year, Nissan has sold 2,294 units, a sales pace off 30.9 percent versus 2013. At its peak in 2010, the Cube remained firmly a niche vehicle, selling 22,968 units.
Nissan North America's Dan Passe, senior manager of product communications, maintains that "We are continuing to sell the 2014 Cube and we haven't made an announcement about future model plans," but Autoblog sources indicate that an official announcement will be coming in the next couple of months, and the Cube has been conspicuously left off of an exhaustive 2015 lineup "Charting the Changes" announcement released on Tuesday.
