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.

The Scoot Quad is Nissan's small step toward EV car sharing

Halfway up Laguna Street, the panic set in. I might not make it up this hill. With my foot depressed all the way to the floor, I sucked in my stomach and started to pray. Yet again, I found myself in an unconventional way to get around on four wheels – but this time, I was on my own, and behind the wheel. Meet the Scoot Quad, aka Nissan New Mobility Concept, aka Renault Twizy. The many aliases reflect the path of descent from its development as a quirky French electric vehicle to its proliferation as a model for car sharing. The Quad resides in San Francisco as part of the Scoot fleet of shared electric vehicles and it's most certainly not for sale. As the line blurs between those who share cars for personal reasons and those who use them for business purposes, Scoot and Nissan came to an agreement in which a small number of New Mobility Concepts would join the Scoot fleet – which currently includes over 300 motorbikes. The added value of Scoot is the capacity for one-way rentals around the city, as well as a dedicated network of charging stations. "We think it's just the best way to get around the city for everyone," said Scoot fleet vice president Mike Waltman, explaining how 10 New Mobility Concepts made their way to San Francisco. Charging time is about four hours on a Level Two charger, made possible through Scoot's network of stations around the city. The one-plus-one Twizy has been in production since 2012 and on sale in certain overseas markets, but it's entirely new for the United States, and it wears the Nissan badge here – kind of. No major changes were made to the Twizy when it became the New Mobility Concept, and similarly none were made in its "transformation" to the Quad. It sports the same insectile shape and the rear profile of a top hat, as well as an identical powertrain: a 13-kilowatt motor that produces 17 horsepower, routed to the rear wheels through a single-speed automatic transmission. Charging time is about four hours on a Level Two charger, made possible through Scoot's network of stations around the city. Its top speed is 50 miles per hour, but Nissan installed a governor at 25 mph to conform to US low-speed vehicle requirements. New Scoot members are required to successfully pass an exam before beginning to use the service, so that was my first order of business. After spending about 35 minutes going through a series of informational videos on the Scoot app, as any new member would do, I was ready to ride Scoot motorcycles.

Nissan didn't have much say in merger talks, but it had what FCA wanted

TOKYO — Nissan wasn't consulted on the proposed merger between its alliance partner Renault and Fiat Chrysler, but the Japanese automaker's reluctance to go along may have helped bring about the surprise collapse of the talks. While Nissan Motor Co. had a weaker bargaining position from the start, with its financial performance crumbling after the arrest last year of its star executive Carlos Ghosn, it still had as its crown jewel the technology of electric vehicles and hybrids that Fiat Chrysler wanted. The board of Renault, meeting Thursday, didn't get as far as voting on the proposal, announced last week, which would have created the world's third biggest automaker, trailing only Volkswagen AG of Germany and Japan's Toyota Motor Corp. When the French government, Renault's top shareholder with a 15% stake, asked for more time to convince Nissan, Fiat Chrysler Chairman John Elkann abruptly withdrew the offer. Although analysts say reviving the talks isn't out of the question, they say trust among the players appears to have been broken. "The other companies made the mistake of underestimating Nissan's determination to say, 'No,' " said Katsuya Takeuchi, senior analyst at Mitsubishi UFJ Morgan Stanley Securities in Tokyo. The Note, an electric car with a small gas engine to charge its battery, was Japan's No. 1 selling car, the first time in 50 years that a Nissan beat Toyota and Honda. Renault and Fiat Chrysler highlighted possible synergies that come from sharing parts and research costs as the benefits of the merger. But what Fiat Chrysler lacks and really wanted was what's called in the industry "electrification technology," Takeuchi said. With emissions regulations getting stricter around the world, having such technology is crucial. Yokohama-based Nissan makes the world's best-selling electric car Leaf. Its Note, an electric car equipped with a small gas engine to charge its battery, was Japan's No. 1 selling car for the fiscal year through March, the first time in 50 years that a Nissan model beat Toyota and Honda Motor Co. for that title. Nissan is also a leader in autonomous-driving technology, another area all the automakers are trying to innovate. "Although Nissan had no say, its cautionary stance on the merger ended up being very meaningful," Takeuchi said.
