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's Taxi of Tomorrow shut down by NYC courts [UPDATE]

Justice Schlomo Hagler may have just put a big dent in Nissan's plans to rule New York City's taxi fleets and outgoing Mayor Mike Bloomberg's vision of a unified fleet of yellow cabs.
As an October 28 deadline approached that would see all current, non-hybrid taxis replaced over by the Nissan NV200 over a three-to-five-year span, the legal battle that's enveloped the Taxi of Tomorrow program from the start has intensified. In a lawsuit, the Greater New York Taxi Association claims New York's Taxi and Limousine Commission overstepped its powers in mandating that taxi fleets are refitted with the NV200, according to the New York Daily News. This isn't the first time the courts have sided with the cabbies in the ToT debate.
Justice Hagler agreed with the cabbies, striking down the Taxi of Tomorrow purchasing requirements, and saying, "Simply stated, the power to contract and compel medallion owners to purchase the Nissan NV200 from Nissan for ten years does not exist in the City Charter," according to The Wall Street Journal.

Recharge Wrap-up: Tesla Model X 0-100 video, Nissan-Renault record EV sales

A video shows that a Tesla Model X can accelerate from 0-100 mph faster than a Model S P85D. DragTimes tested a Founders Edition Tesla Model X P90D with Ludicrous Mode, and found that it did 0-60 mph in 3.178 seconds, which is faster than Tesla's stated 3.2 seconds. The 0-100 mph happened in just 7.98 seconds, which is faster than the 8.3 seconds DragTimes clocked in Model S P85D using Insane Mode. Even more impressive is that the Model X used is a seven-seater with all the boxes ticked, which means that it's lugging a lot of extra weight on the drag strip. DragTimes says it intends to do more tests with other configurations of Tesla models – perhaps we'll get to see how two vehicles with Ludicrous Mode compare. See the video above, and read more at Teslarati. Nissan and Renault saw record sales of electric vehicles in 2015. The two automakers sold 84,754 battery-powered vehicles last year, a rise of 2.5 percent. Nissan Leaf and e-NV200 sales dropped by almost 10 percent, but Leaf sales are expected to improve with the next generation. The Alliance's EV sales, though, were boosted by Renault selling 45 percent more EVs in 2015. Government incentives in France are partially responsible for Renault's success. Since they began selling them, Renault and Nissan have sold 302,000 EVs worldwide by the end of 2015. Read more at Bloomberg Business. A study finds that E20 provides higher peak load capability and thermal efficiency than gasoline in reactivity-controlled compression ignition (RCCI) combustion. The dual-fuel combustion technique uses in-cylinder blending to optimize combustion. The study used E20 ethanol blend or gasoline blended with highway diesel or B20 biodiesel blend and compared the results. In addition to the load capacity and thermal efficiency benefits, E20 also produced fewer hydrocarbon emissions. Read more at Green Car Congress.
