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.

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

Nissan says talks with Renault focused on better competing in electric cars

TOKYO — Nissan's talks with Renault on revamping their alliance are focused on strengthening competitiveness as equal partners and getting the most from their investment in electric cars, the Japanese automaker's CEO told Reuters. The negotiations with Renault, Nissan's top shareholder, have less than two weeks remaining to meet a Nov. 15 target the companies had set to reach a deal, according to people with knowledge of the talks. Nissan Chief Executive Makoto Uchida declined to comment on whether an agreement could be reached this month. But he said he was talking with Renault CEO Luca de Meo every weekend and the talks would be "ongoing for the future." People familiar with the negotiations have said the sharing of technology had emerged as one sticking point. Uchida, who has spent much of his Nissan career in positions related to the Franco-Japanese alliance, emphasised that the talks were based on mutual trust. Each company had valuable technology and discussions of technology transfers were to be expected, he added. He said the goal was to improve the automakers' ability to compete at a time of economic uncertainty and as the industry pushes toward what he described as its biggest transformation in a century with the shift to electric vehicles. "The discussion we are having is about how to make our competitiveness even stronger," Uchida said in an interview with Reuters on Friday. "That's number one." His comments were his first to media since the automakers last month said they were discussing the future of their alliance. The partnership, which began with a 1999 investment from Renault and was long overseen by former executive-turned-fugitive Carlos Ghosn, was critical to turning around the Japanese automaker. But Nissan executives have over the years bristled over the unequal ownership structure, with Renault owning 43% of Nissan and the Japanese automaker holding only a 15% non-voting stake in Renault. People with knowledge of the talks have said the two sides have been discussing a reduction in Renault's stake, potentially to 15%, and the terms under which that could happen. "We want it to be an equal partnership," Uchida said, adding that an "equal partnership would make sense and that would speed up the collaboration even more." He did not comment on potential stake levels.
