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.

Renault-Nissan rejig how they manage Daimler partnership, sources say

PARIS — The Renault-Nissan-Mitsubishi alliance is set to scrap a role overseeing ties with Daimler in favor of individual relations with the German group, three sources told Reuters, as they try to better manage a partnership that has not met initial hopes. The shift comes as alliance-level executive Jacques Verdonck, who was in charge of the cooperation with Daimler, retires at the end of the month, the sources familiar with the matter said. France's Renault will instead rely on its head of partnerships, Sandra Gomez, while Nissan will do the same with Catherine Perez. Mitsubishi will also have a person in charge of partnerships, the sources said, adding the bilateral approach was in line with the new "leader-follower" strategy of the alliance. That involves leaning on the strengths of each carmaker in certain areas. Renault and Daimler declined to comment, while Nissan could not immediately be reached for comment. The plan marks another shift following the end of the Carlos Ghosn era at the alliance. The architect of the Franco-Japanese partnership, who also extended the collaboration to Daimler, was arrested on financial misconduct charges in Japan in late 2018, before fleeing to Lebanon in 2019. He denies any wrongdoing. His exit strained already difficult relations between Nissan and Renault, which are now working to get back on track with cost-saving joint production projects among other steps. The partnership with Daimler - which owns high-end brand Mercedes-Benz, contrasting with the more accessible models produced by the others - has also looked in danger of losing steam. Nissan and Renault, both hit by losses, recently sold down their stakes in the German group. Collaborations on Renault's compact Twingo car and Daimler's Smart model are set to end, and some targets for industrial cooperation have been downgraded over the years. But Daimler still has a factory in Mexico with Nissan, and has been exploring the possibility of jointly developing at least one large van model with Renault. An industry shift towards electric vehicles could yet yield other opportunities, one of the sources said. "The collaboration with Daimler is at present made up of Renault-Daimler projects, Nissan-Daimler ones and some between the three," another of the sources said, with yet another saying that the changes reflected a more pragmatic approach.

Nissan Quest under investigation for inaccurate fuel gauges

After receiving 12 complaints in the last 14 months, the National Highway Traffic Safety Administration has begun a preliminary investigation into a fuel gauge issue with the 2007 Nissan Quest. Drivers have reported that the fuel level gauge will show there's gas in the tank when there actually isn't - in two cases, the digital distance-to-empty gauge indicated more than 70 miles of remaining range - and it will stall out.
This is the second time the 2007-model-year Quest has been involved in the same fuel gauge issue. In 2010 Nissan recalled seven models, including the Quest, from the 2005-2008 model years because of faulty fuel readings. The 12 vehicles in this latest complaint could have slipped through the cracks then, but we'll find out more when NHTSA updates its progress with the investigation into the estimated 37,656 units.
