Nissan sues Ghosn's sister while Renault finds no irregularities in his pay

Nissan sued ousted chairman Carlos Ghosn's sister on Tuesday in a Rio de Janeiro court for "unjust enrichment," according to judicial records seen by Reuters. The suit is the latest twist to a bitter legal fight between Ghosn and Nissan over the contents of a beachfront apartment that the former executive used during his trips to Brazil. Brazilian-born Ghosn is accused of having underreported his income while leading the Japanese carmaker and diverting company funds for his personal use. He is being held in a prison in Japan and the carmaker says there might be evidence of his alleged crimes in the Rio apartment. Additional details regarding the unjust enrichment suit were not immediately available and it was unclear how long it might take to resolve the case. A representative for the Ghosn family did not have an immediate comment. The Japanese press had already reported that Ghosn's sister, Claudine Bichara de Oliveira, could be embroiled in the scandal. Yomuri, Japan's largest daily by circulation, reported in November citing unnamed sources that Nissan's internal investigation had found that Ghosn instructed the company since 2002 to pay some $100,000 a year to his elder sister. The compensation was supposed to be for a role as an adviser. The paper added that Bichara de Oliveira had in fact been living in and managing the Rio apartment that Nissan had bought for the use of Ghosn and that she had done no advisory work for the car maker. Meanwhile, Renault issued a preliminary report indicating that an audit launched in the wake of Chairman and CEO Carlos Ghosn's arrest in Japan had so far found no irregularities with his pay at the French carmaker. Ghosn was charged on Monday in Japan for failing to declare deferred income he had agreed to receive from Nissan, for the five years ending March 2015. There is speculation that Nissan itself may be indicted in Japan as part of the case against Ghosn. While Nissan fired Ghosn days after his Nov. 19 arrest, Renault has resisted pressure to replace him permanently. The Renault board also "noted that, at this stage, it does not have information concerning Carlos Ghosn's defense," the company said after its meeting, which had long been scheduled to discuss 2018-19 financial accounts. During the five-hour session, several directors led by Cherie Blair, wife of the British former prime minister Tony Blair, began to express impatience with that position, two people with knowledge of the matter said.

10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.

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.
