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.

Nissan Recalls More Than One Million Vehicles For Air Bags

Nissan is recalling just over one million cars, SUVs and vans because the front passenger air bags may not inflate in a crash. It's the company's second recall to fix the same problem. The recall affects the Altima midsize car, Leaf electric car, Pathfinder SUV and Sentra compact models from the 2013 and 2014 model years, as well as the NV200 Taxi van and Infiniti JX35 SUV from 2013. Also covered are the Infiniti QX60 and Q50 SUVs from 2014. In documents filed with the National Highway Traffic Safety Administration, Nissan says the vehicles' computer software may not detect an adult in the passenger seat. If that happens, the air bags won't inflate. Nissan will notify owners and dealers will update the software for free. The recall is expected to start in mid-April. Most of the vehicles were recalled in February of last year for a similar problem. Dealers replaced seat sensors, but Nissan said it continued to get consumer complaints and warranty claims in vehicles that had been repaired. Front passenger seats have sensors that determine the passenger's weight and turn off air bags off if a child is on board. The malfunctioning sensors can turn the air bags off even if an adult is in the seat. Nissan received three reports of air bags failing to inflate in a crash. Spokesman Steve Yeager said in an e-mail that he is not sure if anyone was hurt in those incidents. There have been no deaths due to the problem, he said. The recall affects almost 990,000 vehicles in the U.S., another 60,000 in Canada and small numbers in other countries, Yeager said. Related Gallery Nissan Searches For Identity In America

Facts point to legal violations by Carlos Ghosn, says Nissan external review

YOKOHAMA, Japan — An external committee reviewing governance at Nissan Motor Co said on Wednesday there were enough facts to suspect violations of laws and the private use of company funds by ousted chairman Carlos Ghosn. Following a three-month audit of Nissan's governance after a scandal that shook the global auto industry, the committee put the blame squarely on what it called Ghosn's concentration of power. It also acknowledged Nissan CEO Hiroto Saikawa's role in Ghosn's salary arrangement at the heart of the scandal. Twenty years to the day since French automaker Renault SA agreed to rescue Nissan, the committee described a corporate culture at Nissan "in which no one can make any objections to Mr. Ghosn," who was "in a way deified within Nissan as a savior who had redeemed Nissan from collapse." A representative for Ghosn replied in a statement that the allegations made against the former Nissan chairman "will be revealed for what they are: part of an unsubstantiated smear campaign against Carlos Ghosn to prevent the integration of the Alliance and conceal Nissan's deteriorating performance." The group issued 38 recommendations to bolster Nissan's governance, including that top executive positions at the Japanese car maker should not be held by people serving in executive positions at Renault or junior partner Mitsubishi Motors. It also proposed that the majority of directors, including the chairman of the board, be independent, outside directors and that the role of company chairman be abolished. Responding to the committee's comments, Saikawa told reporters on Thursday that Nissan would seriously consider the committee's recommendations, which he characterized as "tough." Saikawa, who was speaking outside his home, did not specifically address his responsibility in the scandal but has previously said that top management, including himself, were responsible for weak governance which led to the misconduct. The recommendations from the external, seven-member committee came weeks after Nissan and Renault said they would retool their alliance, one of the world's biggest automaking groupings, to break up the all-powerful chairmanship previously held by Ghosn. "There are facts sufficient to suspect violations of laws and regulations, violation of internal rules and private use of company funds and expenses ... by Mr. Ghosn," the committee said in its report.
