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 in Twitter debut vows to 'tell the truth about what's happening'

TOKYO — Ousted Nissan boss Carlos Ghosn's sudden appearance on Twitter on Wednesday was a surprise move by the businessman that perplexed people and sent journalists scrambling, and not for the first time. The first tweet from the @carlosghosn account on the social network read, "I'm getting ready to tell the truth about what's happening. Press conference on Thursday, April 11." It did not specify a time or place. Featuring a photo of a smiling, grey-haired Ghosn standing in front of a tree with seasonal cherry blossoms, the account initially lacked the blue tick mark to show it had been verified by the social network. That left journalists unsure of its authenticity — particularly as the conditions of Ghosn's $9 million bail preclude him from using the internet. This content is hosted by a third party.

Forty minutes later, when the blue tick appeared, the tweet swept across social media and the account's followers swelled to almost 20,000, from just a handful earlier. Some of the replies appeared sympathetic to Ghosn, with others carrying photos of his now-famous exit from a Tokyo detention center last month. "Stood right alongside you with #GiveGhosnBail. Looking forward to hearing your side," wrote one Twitter user with the name @highmileage. Ghosn had also caught media off guard when he disguised himself in a workman's uniform, cap and face mask to try and give waiting reporters the slip on leaving the detention center after his release on bail. The architect of the Nissan and Renault SA global alliance was then pursued by media as he rode away in a small work van, a Suzuki, topped with a ladder. Ghosn's dramatic fall from grace began with his arrest in November after getting off a private plane at Tokyo's Haneda Airport. He has since been charged with financial misconduct and aggravated breach of trust. On Wednesday, the Yomiuri newspaper said Tokyo prosecutors will soon decide whether to prosecute Ghosn on further charges. A further arrest could jeopardize the planned news conference. It remains unclear if Ghosn sent the tweet or it was sent on his behalf. His bail conditions allow him to access a computer at his lawyer's office but forbid him to use the internet.

It won't be long now before Nissan Leaf finally overtakes Chevy Volt

The two best-selling plug-in vehicles ever are the Chevy Volt and the Nissan Leaf. When the two vehicles launched in late 2010, the plug-in hybrid Volt quickly outpaced the all-electric Leaf and, despite lots of ups and downs since then, continues to hold on to a cumulative sales lead. This will change in 2015. Cumulatively, from November 2010 through November 2014, the Volt sold 71,867 units while the Leaf trails with 69,220. That's a difference of just 2,647. Based on current trends (with the Leaf selling around 2,500-2,700 a month and the Volt at 1,500-1,700) we expect the Leaf to take over either in January or, more likely, February when the Leaf takes over as the most popular plug-in car in America. Perhaps even March, depending on how low the numbers are for January and February, which are always slow sales months in the US. Of course, once it takes the crown, the Leaf can't expect to easily hold on for long. A new Volt is coming in the second half of 2015, likely beating a new Leaf to market. The question is, then, how well the Chevy sells with all of its new bells and whistles. Do you think the Volt will be the comeback kid once the 2016 model becomes available?
