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, Fisker in advanced talks on investment, partnership

Nissan is in advanced talks to invest in electric vehicle maker Fisker in a deal that could provide the Japanese automaker with access to an electric pickup truck while giving the struggling startup a financial lifeline, according to two people familiar with the negotiations. The deal could close this month, said the sources, who asked not to be identified because the talks are ongoing and have not been finalized. Terms being discussed include Nissan investing more than $400 million in Fisker's truck platform and building Fisker's planned Alaska pickup starting in 2026 at one of its U.S. assembly plants, one of the sources said. Nissan would build its own electric pickup on the same platform, the source said. Nissan has U.S. assembly plants in Mississippi and Tennessee. Fisker said on Thursday, when it announced it might not be able to continue as a going concern and would cut 15% of its workforce, that it was in talks with a large automaker for a potential investment and joint development partnership. It did not name the automaker. A Fisker spokesman said the company does not comment on speculation, while Nissan officials were not immediately available to comment. Fisker shares had been down about 45% before the Reuters report but pared those losses and were trading down about 25% with a market capitalization of more than $295 million. The term sheet is ready and the deal is going through due diligence, one of the sources said. Nissan was an EV pioneer with its fully battery powered Leaf hatchback in 2010 but has since struggled in the face of nimbler new entrants. A deal with Fisker would help it move into the growing U.S. electric pickup market. Nissan's talks with Fisker comes in the wake of the former's “rebalanced” relationship with its long-time alliance partner Renault. Last year, Nissan and Renault finalised terms of a restructured alliance after months of negotiations. They aim to have cross-shareholdings of 15% as part of the deal. The more limited alliance removes certain restrictions and has opened the door for Nissan to develop growth plans in areas such as EVs and software independent of Renault, said one of the sources, who is familiar with Nissan's thinking. The Yokohama-headquartered automaker is scouring “many, many opportunities,” the person said.

Porsche wins the 2015 24 Hours of Le Mans

The question going into this year's 24 Hours of Le Mans was whether or not the Porsche 919 Hybrid would be able to combine its qualifying pace with race reliability. After battling neck-and-neck with Audi's R18 for most of the race, the answer is a resounding yes. Not only did Porsche drivers climb the first two spots on the podium, they did so without any major mishaps on track. This win is the first overall trophy for Porsche since 1998. Audi previously won the last five races, and 13 of the last 15. Corvette also returned to the winner's circle, with the No. 64 C7.R taking winning the GTE Pro division. The victory is the first class win for Corvette since 2011. KCMG won the LMP2 class in ninth overall. With 45 minutes to go the No. 98 Aston Martin crashed out of first place in GTE Amateur, giving the class win to SMP Racing's Ferrari and second place to the Patrick Dempsey Racing Porsche 911 RSR. For the full list of official results, click here. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. For most of the race, the battle at the top went back and forth between the two German manufacturers. An tire puncture in the No. 7 Audi gave up the lead to Porsche, and moments later a crash forced the No. 8 into the garage. But a three-minute replacement of the front and rear bodywork kept the Audi in contention. As the race wore into the night, Porsche maintained a slightly faster pace than Audi. Nick Tandy took the lead on Lap 253 early Sunday morning, and car No. 19 never gave up the top position. The win is the first for all three drivers of the No. 19 – Nico Hulkenberg, Earl Bamber, and Nick Tandy. A lap behind in second was the No. 17 Porsche. The Audis fought reliability problems late in the race but still finished third with the No. 7 R18. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. As the Aston Martin cars dropped away, the lone Corvette Racing entry took over, followed by a charging AF Corse team Ferrari 458 Italia. The Corvette and Ferrari continued to trade places in the final hours until gearbox trouble forced the No. 51 Ferrari out of contention. It was eventually passed by the other AF Corse car, No. 71. Nissan experienced all the pain of a first-year effort with its front-wheel-drive GT-R LM Nismo.
