Nissan Leaf battery cells put through torture test, live to charge again

One minor chink in the armor of the Tesla Model S is that a small number have caught fire, once their battery packs were penetrated. Nissan Leaf drivers, however, might just be able to weather such an event without an ensuing CarBQ. Our evidence for such a claim? A video that has surfaced of cells from a Leaf pack undergoing a battery of torture tests (pun somewhat-ashamedly intended). Shared by folks at the Hybrid Auto Center in Las Vegas – who offer for sale, among other things, used Leaf lithium battery modules – the footage shows salvaged cells being brutally assaulted with a screwdriver, and later, a propane torch. Granted, these tests are not the same thing as flinging a piece of metal into a working pack at 70 miles per hour, but they do claim to show that a puncture does not always equal a fire. Oh, and don't try this at home. When pierced through by the flat head tool, there is no explosion or eruption of flame. Instead, a rather modest wisp of smoke shyly emerges as the electrolyte next to the shorted area of the fully-charged foil pouch reacts with the influx of oxygen. Again and again, the blade descends, until the cell is riddled with holes. No fire. Amazingly, when connected with a voltmeter afterward there are still plenty of signs of life, and when it is charged and discharged (off-camera), it reportedly suffers only a slight loss of charge capacity. The video goes on to show another cell attacked with open flame with similar results. While the demonstration is, perhaps, somewhat crude, the message it sends is loud and clear: lithium batteries can be safe and rather robust, despite some freak accidents.

Carlos Ghosn video: 'This is about conspiracy. This is about backstabbing'

TOKYO — Nissan's former Chairman Carlos Ghosn maintained his innocence in a video released by his legal team Tuesday and accused some executives at the Japanese automaker of a "conspiracy" that led to his arrest on financial misconduct allegations. "The first message is that I'm innocent," said Ghosn, wearing a white shirt and dark jacket and speaking calmly in the nearly 10-minute video shown at the Foreign Correspondents' Club in Tokyo. "This is a conspiracy," he said. "This is not about specific events, this is not about, again, greed, this is not about dictatorship. This is about a plot. This is about conspiracy. This is about backstabbing." His lawyer Junichiro Hironaka said the video was prepared in case Ghosn was not able to speak at a news conference planned for Thursday. Ghosn was arrested last week while out on bail and remains at the Tokyo Detention Center. Ghosn said the executives behind the conspiracy were motivated by what he called "selfish fears," including what they saw as a merger with French alliance partner Renault SA. They mistook his leadership for greed and dictatorship, when he was the biggest defender of Nissan's autonomy, Ghosn said. He also said he was worried about Nissan, wondering whether those executives were really watching out for the company. Hironaka said a section of the video in which Ghosn mentioned names was removed on his legal advice. Nissan Motor Co., while declining to comment on the criminal case, has said an internal investigation has found that Ghosn falsified financial documents to under-report compensation, and that he used Nissan money for personal gain. "Nissan's internal investigation has uncovered substantial evidence of blatantly unethical conduct," company spokesman Nicholas Maxfield said when asked for comment on Ghosn's video. "The company's focus remains on addressing weaknesses in governance that enabled this misconduct." Ghosn's fourth arrest was on a fresh breach of trust allegation based on suspicion that payments from a Nissan subsidiary to an Oman dealership were diverted to a company effectively run by Ghosn. On Monday, Nissan Motor Co. shareholders voted to oust Ghosn from its board and to approve the appointment of French alliance partner Renault SA's Chairman Jean-Dominique Senard as Ghosn's replacement. Renault owns 43 percent of Nissan.

What happens to Renault-Nissan after Ghosn is gone?

Carlos Ghosn is a very, very busy man. Like, really busy. As in, he heads up three automakers (and their subsidiaries), running facilities in 68 countries and selling vehicles in 170 different markets across the globe. He flies over 300,000 miles per year and works 15 to 16 hours a day, just to manage an alliance between the Japanese and French that's responsible for an expected $140 billion in sales this year alone. The Chairman and CEO of the Renault-Nissan Alliance, Ghosn has managed a number of remarkable feats during his time at both automakers, but there are some that are questioning how much longer the 60-year-old exec can handle the punishing nature of his responsibilities. According to Fortune, six months ago Ghosn signed a four-year contract to continue running Renault, while his tenure at Nissan will continue until at least 2017. Beyond that, though, the future is rather murky, and it's made worse by the high-level turnover that Renault-Nissan has experienced over the past few years, losing execs like Carlos Tavares, Johan de Nysschen and Andy Palmer. Fortune has an excellent, and lengthy, feature on Ghosn, his responsibilities and the danger posed to Renault-Nissan by his departure. If you're at all curious about what the exec has done for the two automakers, how this alliance has worked when so many other industry partnerships have failed and just what a post-Ghosn future may hold, head over and have a look.
