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's lead over Renault Zoe narrows in Europe

The Nissan Leaf has seen its sales steadily decline in the US for a while now. Here, its been eclipsed by the second-generation Chevrolet Volt extended-range plug-in while people await the next-generation version of the all-electric Leaf. The EV may be starting to receive a similar response across the Pond. While the Leaf remains Europe's biggest-selling EV, that lead is eroding, as sales of the Renault Zoe are catching up, according to the European Alternative Fuels Observatory (EAFO). It's a good thing Nissan and Renault are sister companies. Through May, Nissan sold about 9,500 Leaf vehicles in Europe. The good news is that number is up 37 percent from a year earlier. There's disconcerting news, too, and that is that the Renault Zoe's sales have surged 60 percent this year to almost 9,400 units. So, for all we know, the Zoe may have caught up with the Leaf last month. Still, both models are outpacing demand for the Tesla Model S and Volkswagen e-Golf: the former's sales are little-changed this year, while the latter model's sales have dropped 34 percent. The BMW i3, Kia Soul EV, and Mercedes-Benz B250e all have had higher sales this year. As for plug-in hybrids, the Mitsubishi Outlander PHEV has maintained its substantial European lead, almost doubling sales of the Volkswagen Golf GTE and totaling almost 9,400 units sold through May. Meanwhile, the new Volvo XC90 PHEV has leapfrogged models such as the Volkswagen Passat GTE, Mercedes-Benz C350e, and Audi A3 e-Tron into third place behind the Mitsubishi and VW. Here in the US, Nissan Leaf sales through June fell 41 percent from a year earlier to about 5,800 units, while Chevrolet Volt sales have surged 75 percent to 9,808 units.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
