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 Leaf is now the best-selling plug-in vehicle of all time in US

Numbers don't lie. And in some instances, you can see their truth from miles away. As everyone expected, the Nissan Leaf is now officially the best-selling plug-in vehicle in the US. While the two vehicles aren't direct competitors (one's a pure EV and the other is a plug-in hybrid), they certainly dominate the plug-in vehicle sales charts. When we do a little math on those charts, we see that since the two vehicles went on sale at the end of 2010, the Volt has sold 75,231 units while the Leaf is now at 76,407, giving the Leaf a 1,176-vehicle lead. The Leaf trailed the Volt by just two units at the end of February. This is the first time the EV had held the overall lead since the end of February 2012, when it was ahead 10,847 to 9,623 and for a while there at the end of 2013, the Volt was up by around 12,000 units. Times have changed, though, and we don't expect the lead to switch back until the next-gen Volt goes on sale later this year, and even then nothing is certain. The Leaf sold 1,817 copies last month, a drop of 27.5 percent from last year. Year-to-date, the Leaf has sold 4,085 units, down 21.2 percent from the same time period in 2014. There were 639 Volts sold last month, a 56.8-percent sales decrease compared to March 2014. So far this year, Volt sales are down 48 percent. Green Chevrolet Nissan ev sales hybrid sales

Ghosn shares 'truth about Autonomous Drive cars'

Drive our cars. No, wait, don't drive our cars. Nissan chief Carlos Ghosn is delivering a message about autonomous driving that's less mixed than it sounds on the surface. As part of his public dialogue from LinkedIn's "Influencer" series, Ghosn said in a company announcement that "hands-free" driving is part of the Japanese automaker's "near-term technology." In fact, cars that can self-drive in heavy, stop-and-go traffic, may be ready for the market by late 2016. That should please texters everywhere. 2018 may be the year cars with lane-changing, hazard-avoiding capabilities will see the light of day, while by 2020, Nissan may feature a "complete package" of autonomous-driving features, Ghosn writes. As for the proverbial driver-less car? That's at least a decade out but ultimately likely, according to Ghosn. Nissan said early last year that some autonomous versions of its vehicles may be available in the US by the end of the decade, and that it was in talks with California regulators about the idea of self-driving cars on the state's roads. Nissan has worked with institutions such as MIT, Stanford and Oxford at developing autonomous-drive concepts, and has tested self-driving versions of the Leaf electric vehicles in Japan. Check out excerpts of the Ghosn "interview" below. The truth about Autonomous Drive cars, by Carlos Ghosn The following is the latest from Carlos Ghosn's LinkedIn Influencer series. Read all of Mr. Ghosn's LinkedIn Influencer articles here. There has been a lot of talk in the media recently about "Autonomous Drive" technology and a potential future of driverless cars. No doubt, Autonomous Drive technology will change how we approach driving. I expect it to result a significant transformation in transportation. But all the talk has left many drivers a bit confused. After years of promoting "eyes on the road, hands on the wheel," the auto industry is now talking about reading your email or a book while you drive – and the prospect of maybe not even needing a driver. So it's a good time to address the questions that arise whenever this subject comes up: Q: What is Autonomous Drive? A: Autonomous Drive combines the technology of robotics, artificial intelligence, sensors and car-to-car connectivity. It is a range of technologies that will be added to our cars over the next several years.
