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.

December sales for Chevy Volt, Nissan Leaf are what you expected

It was another month of as-expected sales for the two pioneering plug-in vehicles in the US. The Nissan Leaf is basically treading water and the new-generation Chevy Volt is getting back to old habits with a big increase in sales compared to where the car was last year. It wasn't a surprising month, but there wasn't any reason to expect a surprise. In fact, we don't suspect this trend to veer too far from where it's at right now until gas prices shoot up or Nissan introduces a new Leaf. Neither of those things is likely to happen any time soon. Let's start with the mediocre news. Nissan reported today that Leaf sales for December 2015 totaled 1,347 units. That's a 56.6-percent drop from where the Leaf was a year ago, and contributed to the all-electric vehicle's 42.8-percent drop in 2015 sales compared to 2014. This past year, 17,269 people bought Leafs, down from 30,200 who did so in 2014. The Volt sold 2,114 copies last month, bringing the plug-in hybrids 2015 total up to 15,393. That's an 18.1 percent drop from the 18,805 Volts sold in 2014. We shouldn't see the past year as a total flop for the Volt, though, since the much-improved second-generation model was introduced late in the year. In fact, if we just look at December 2015 and compare it to the last month of 2014, we see the Volt was able to post a 41.9-percent increase. It'll be quite fun to see where the Volt's numbers go in 2016. As you probably know, we'll have our complete wrap up of green car sales for you soon. Stay tuned.

Nissan tells Renault it is 'not opposed' to Fiat Chrysler merger plan

TOKYO – Nissan on Wednesday told Renault it wasn't opposed to its partner's potential $35 billion merger with Fiat Chrysler, the Nikkei newspaper said, as the two met to hash out the future of their alliance amid a deal that could upend the auto industry. The leaders of Nissan Motor Co, France's Renault SA and junior partner Mitsubishi Motors Corp gathered at Nissan's headquarters in Yokohama for a scheduled alliance meeting - one overshadowed by Fiat Chrysler's proposal this week for a merger-of-equals with Renault. The plan, which would create the world's third-largest automaker, raises difficult questions about how Nissan would fit into a radically changed alliance. Renault Chairman Jean-Dominique Senard arrived in Japan on Tuesday to discuss the proposed tie-up with Nissan, 43.4% owned by the French automaker. "We are not opposed," the Nikkei quoted an unnamed Nissan source who had attended the meeting as saying. The person also said "many details need to be worked out" before the Japanese automaker solidifies its position on the issue, the Nikkei reported. In a statement, the alliance members confirmed that they had "an open and transparent discussion" on the proposal. The deal looks designed to tackle the costs of far-reaching technological and regulatory changes, including the drive toward electric vehicles. Nissan, which has rebuffed overtures by Renault for a merger of their own despite their 20-year alliance, was blindsided by the discussions, sources have told Reuters, stoking concerns that a deal with Fiat Chrysler could weaken Nissan's relations with Renault. The tie-up also poses an additional challenge for Nissan CEO Hiroto Saikawa, already grappling with poor financial performance and an uneasy relationship with Renault after Nissan led the ousting last year of long-standing alliance chairman Carlos Ghosn. There have long been tensions between Nissan and Renault over the imbalance of power in their alliance. Nissan, the bigger company, holds a 15% non-voting stake in the French automaker, while Renault owns 43.4% of Nissan. Ahead of Wednesday's meeting, Japanese media quoted Saikawa as telling reporters that he would look at the potential opportunities afforded by a Renault-FCA merger. Credit ratings agency Moody's said it was vital for Nissan to stabilize its partnership with Renault to expand operational synergies and improve margins.
