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.

Robert Llewellyn fast-charges long-distance Leaf EV drive in UK

A British actor likely best known in his country for his role in the 1980s and 90s comedy series Red Dwarf has just made a pretty good case for driving green automobiles. Last week, Robert Llewellyn has completed an 862-mile round trip between London and Edinburgh in a Nissan Leaf and says he was able to save time by finding enough fast-charging stations the entire way, UK website Excite/Motoring says. Llewellyn, along with co-driver David Peilow, knocked out the London-to-Edinburgh leg in a single day, in part because of the British network of about 150 fast-charging stations. Llewellyn used his Twitter feed to update the general public of the two drivers' progress, noting that the first leg took about 13 hours. The round trip was completed January 26. Nissan can use all the positive publicity in can get, as UK sales of the all-electric vehicle failed to keep pace with the surging rate of demand in the US, where 2013 Leaf sales more than doubled from a year earlier to 22,610 units. In fact, in the UK, Nissan started offering incentives last month, things like free quick charging at Nissan dealerships, the ability to borrow gas-powered Nissans for free and free towing.

Nissan, Infiniti will each show a next-gen concept EV in Detroit

The chief designer for Nissan and Infiniti said Wednesday that both brands will debut concept electric vehicles at the 2019 North American International Auto Show in Detroit in January that will likely show off Nissan's next-generation electric drive systems and the evolution of the brands' EV design direction first hinted at with Infiniti's stunning Q Inspiration. Alfonso Albaisa, senior vice president of global design for Nissan, said the concepts will reflect a similar departure from standard vehicle proportions as the Q Inspiration. He would not say exactly what segment or segments the concepts would represent, but he dropped some hints at a couple possible powertrains for the concepts. Similar additional concepts will follow later in the year at the Tokyo Motor Show, he said. "The Q Inspiration kind of hinted at it and we avoided discussing too much about what's driving that car. Of course, we talked about VC-Turbo, which is also possible," he said in an interview with Autoblog. "But if you really look at the car, Q Insipiration shifted the cabin forward. It was the first one to break the [mold] of Infiniti. So how to still have this artistry and this sense of carrozzerie" (Italian for coachbuilding) "of Infiniti without kind of the stereotypical long hood and the cabin shifted back and the windshield has to go through the center of the front wheel, these golden rules." Infiniti debuted the Q Inspiration concept sedan in Detroit in January, with a swoopy, ghost-like design influenced by an archer shooting an arrow through the air, and innovative design features like an elongated cabin that expands interior space, a relative lack of chrome, and other features. It's powered by a compact variable compression turbocharged engine, which can change compression ratios on the fly to maximize efficiency and power, depending on the situation. But Albaisa said the two concepts for Detroit could feature Nissan's e-Power series hybrid technology, which has mostly featured in Japan, and which features small, isolated gasoline engines that exist only to charge the batteries, not drive the wheels. They will also feature a new generation of battery packs, which he calls a "magic carpet." "It's getting denser, it's getting thinner, the cars are able to get a little bit bigger, more space, we can really do much more," he said.
