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 CEO Saikawa admits he was overpaid, in policy violation

TOKYO — Nissan Motor Co was embroiled in another scandal over executive pay on Thursday after Chief Executive Hiroto Saikawa admitted to being overpaid in violation of internal procedures under a scheme designed by ousted Chairman Carlos Ghosn. An internal investigation found that Saikawa and other executives had received improper compensation, a source with knowledge of the matter told Reuters, raising doubts about Saikawa's pledge to improve governance in the wake of Ghosn's arrest last year for alleged financial misconduct. Saikawa apologized and vowed to return any improperly paid money as he admitted to Japanese reporters earlier on Thursday that he had wrongly received stock-related compensation under "a scheme of the Ghosn era." "I am deeply sorry for causing concern," Saikawa said, according to Jiji Press. In other comments reported by Kyodo news, Saikawa denied any direct role in the execution of a stock appreciation rights (SAR) scheme and said he thought "proper procedures" had been taken. The improper payments, including tens of millions of yen Saikawa received through the SAR scheme, were disclosed on Wednesday at a meeting of Nissan's audit committee, said the source who declined to be identified because the information is not public. Disciplinary action regarding the issue would be discussed at an upcoming board meeting, the source added. Nissan said in a statement that the findings from its probe including issues related to the share appreciation rights would be submitted to its board on Sept. 9. The company has been trying to strengthen governance, slash costs and boost flagging profitability amid persistent allegations of financial misconduct stemming from Ghosn's 20-year reign at Japan's second-biggest automaker. Ghosn is awaiting trial in Japan over charges including enriching himself at a cost of $5 million to Nissan. Kyodo reported that proceedings could start as early as March. He denies any wrongdoing and says he is the victim of a boardroom coup. Confidence in Saikawa had already been shaken by accusations he was too close to Ghosn, whose arrest in November rocked the global auto industry and exposed tensions in the automaking partnership between Nissan and Renault SA.

Nissan Leaf sells 3,186 in best month ever as Chevy moves 2,511 Volts

The end of summer seems to inspire people to go out and buy a lot of plug-in vehicles. Last year, for example, the Chevy Volt had its best month ever in August, with 3,351 sales. This year, the Nissan Leaf is going up to the winner's podium, setting its own best-ever record with 3,186 units sold. This beats the Leaf's previous record by 69 vehicles. This beats the Leaf's previous record of 3,117 set in May 2014 by 69 vehicles and is up 31.7 percent from August 2013. Nissan is once again quick to remind us that the popular EV's record sales streak has now been extended to 18 months in a row. This record is simply noting that the current month, in this case August, had the highest sales that that month has ever seen in the US. Over all, US Leaf sales are up 34.1 percent so far this year. In a prepared statement, Nissan's director of Leaf sales and infrastructure, Brendan Jones, said that the Leaf is selling well on both coasts, including cities like Raleigh, Boston and Washington, DC. "It's what we call the 'cul-de-sac phenomenon,' where once someone in a community buys a Leaf, then friends, family, co-workers and neighbors see the benefits of this fun-to-drive electric vehicle firsthand and are sold on the idea of going electric," he said. The Volt also had a good month - its best of 2014 by almost 500 sales – but the 2,511 Volt sales still represent a drop of 25.1 percent from the excellent sales the Volt had this time last year. In fact, August 2014 represents the Volt's best sales month since, well, August 2013. Apparently, there's just something about the end of summer. As always, we are working on our in-depth round-up of green car sales across the country and will have that up soon.
