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 announces 5-year/100,000-mile bumper-to-bumper warranty for commercial vehicles

Nissan is a relative new-kid when it comes to the commercial van market in the US, with its commercial vehicles division only introducing the first NV vans in February 2011. But Nissan isn't letting its newcomer status keep it from challenging the established players in the segment. The company's latest shot over competitors' bows is announcing that, starting for the 2014 model year, its NV Cargo, NV Passenger and NV200 Compact Cargo vans carry a best-in-class, five-year/100,000-mile bumper-to-bumper warranty. Their powertrain coverage also gets a 40,000-mile increase to five years/100,000 miles.
The new warranty is a huge leap over adversaries in the segment and should lure in some buyers looking for a longer term of coverage. The Mercedes-Benz Sprinter, Ram ProMaster, Ford Transit and Transit Connect all carry a three-year/36,000-mile bumper-to-bumper warranty. The Fords offer five years and 60,000 miles of powertrain coverage, while all of the others increase that to 100,000 miles. Until this announcement, Nissan had the standard thee years of coverage, as well.
The Japanese automaker is clearly hungry to grab a bigger piece of the commercial van pie. Its heavy-duty NV vans have a relatively small 5.3 percent market share in their segment as of May 2014, according to the company's figures, but the NV200 is doing better with a 19.4 percent share. The division as a whole is on the upswing, though, with sales up 88 percent so far in 2014. With just a few years under its belt, Nissan Commercial Vehicles seems unafraid to challenge the status quo in the segment. Let's see how buyers respond.

Recharge Wrap-up: Renault-Nissan at COP21, fast charging viability

Nissan and Renault's combined fleet of 200 EVs drove over 175,000 kilometers (about 108,700 miles) during the COP21 environmental summit in Paris. The largest fleet of EVs for any international conference served as shuttles for attendees, saving almost 182 barrels of oil and 18 tons of CO2 emissions. In addition to providing the Nissan Leaf, Nissan e-NV200, and Renault Zoe EV shuttles, the Renault-Nissan Alliance also set up a network of 90 chargers to support the fleet. 13 of the 27 quick and semi-quick chargers will remain in place for public use.

The company will implement new and upgrade existing traffic technologies in the city, including cloud-based traffic management software, local controller software and an adaptive traffic control system designed to improve traffic flow and safety. In a college town with highly varying numbers of students and visitors throughout the year, "the need to move traffic in and out of the city efficiently is crucial not only for economic and environmental impacts, but for quality of life for Ann Arbor residents," says Marcus Welz, president of Siemens Intelligent Traffic Systems. Many Ann Arborites (your author included) would surely agree.

The researchers found parking spots to be the most popular public charging locations, and that fast chargers saw the most frequent use, suggesting commercial viability for the infrastructure in the short- to medium-term. The study also found that most drivers prefer to charge at home, and do so during peak hours. Incentivization could be necessary to break people from this habit. Read more at Green Car Congress.
