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.

Semi-autonomous Nissan Leaf certified for road use in Japan [w/video]

In order to meet its goal of having an autonomous car in production by 2020, Nissan is going to have be able to test its technology in real-world driving conditions. For this, the automaker has just received a license plate to legally test its semi-autonomous driver assist systems in Japan, marking the first time such technologies have been tested on that country's roads. Not ironically, the license plate number is 2020.
Though not fully autonomous, this Leaf prototype will test various components of a self-driving car including exiting the highway, the ability to stay in its lane and change lanes when needed, stopping at red lights and overtaking stopped or slow traffic. Nissan is also in the process of building a proving ground in Oppama, Japan dedicated solely to autonomous cars, but the ability to test on public roads will obviously play a crucial role in the development of these cars. Scroll down for a short video and press release Nissan posted to mark the occasion.

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.
