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 Sport Sedan Concept foretells a future Maxima

Nissan is in the midst of overhauling its design language. We got our first glimpse at the direction its style was going a year ago with the Resonance crossover concept, which was followed in Shanghai by the connected-car Friend-Me hatchback concept. And now, after dropping a few hints, Nissan has revealed the third in this developing series.
Unveiled at today's Detroit Auto Show, the new Sport Sedan Concept applies many of the same design elements we've seen on Nissan's previous show cars to a more conventional four-door shape. But far from a design exercise, the decidedly uncreatively named Sport Sedan Concept previews "a future production sports sedan," which has every indication of being the next Maxima.
Its dimensions reveal the concept to be bigger than the current Maxima in every direction but height, with that visual impression further entrenched by a floating roof design that combines with a high waistline to give a coupe-like profile. There are also sharp creases in the bodywork that visually break up the space between the rear set of 21-inch alloys and the tapered greenhouse. The shape is further punctuated by the V-shaped grille and distinctly Nissan boomerang-shaped lights that lend a face to this distinctly Japanese design that was penned in California and honed back in Japan. The sharp and simple cabin is characterized by a high-contrast palette with quilted leather and metallic trim.

Nissan could offer plug-in hybrids by 2016

Nissan is recharging the idea of a production plug-in hybrid model. The Japanese automaker may start making a plug-in hybrid by as soon as late 2015, with deliveries to start in time for the 2016 model year, Green Car Reports says, citing an interview with company executive Andy Palmer. Those comments go against what Nissan said during the North American Auto Show in January. Palmer didn't specify what class of vehicle the plug-in hybrid would be, but he said battery-electric vehicles are best suited for cars 3,850 pounds or lighter, according to Green Car Reports. That would imply that the plug-in hybrid powertrain may be used for a mid-sized sedan or a crossover vehicle. Either way, a Nissan PHEV may pair the Nissan Leaf's 108-horsepower electric motor with a gas engine. Whether Palmer's projected timeframe was more of a ballpark estimate is anyone's guess, as the company hasn't made official plans for a 2016 model-year plug-in hybrid, Nissan spokesman Tim Gallagher wrote in an e-mail to AutoblogGreen. Either way, feel free to join us in the comments below. Nissan is coming off its best-ever sale month for the Leaf, which has moved about 115,000 units around the world. Domestic sales of the Leaf in May rose 46 percent from a year earlier to a monthly record 3,117 vehicles. Through the first five months of the year, Leaf sales increased 36 percent, to 10,389 units.
