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-Renault and game developer plan driverless ride-hailing

TOKYO - The Nissan and Renault alliance plans to launch driverless ride-hailing and ride-sharing services in coming years, as the automakers look beyond making and selling cars to survive an industry being quickly transformed by new services. Automakers are leveraging expertise in automated driving functions for mass-market cars to develop mobility services, as they compete with tech firms such as Alphabet Inc and Uber in the fast-growing "pay-per-ride" market which threatens to hit demand for car ownership. Ogi Redzic, head of Nissan-Renault's Connected Vehicles and Mobility Services division, said the alliance would begin self-driving services based on its electric cars "certainly within 10 years," though not likely before 2020. "We think that the big opportunity for us is in automation, electric vehicles and ride-sharing and hailing together," Redzic said in an interview on Thursday. Nissan and Renault join a small group of automakers aiming to enter the ride-hailing market, which Goldman Sachs last month estimated would grow eightfold by 2030 to be five times the size of the taxi market. Redzic said the Japanese and French partners were testing self-driving vehicles, and that any service would run on pre-mapped courses with predetermined pick-up and drop-off points. The two automakers are developing the system with Japanese game software maker DeNA Co Ltd and French public transport operator Transdev SA. German rival BMW AG is also testing autonomous vehicles for use in ride-hailing services, while Uber has been developing self-driving technology. U.S. tech firm nuTonomy Inc and ride services company Lyft Inc, which counts General Motors Co as a major shareholder, this month announced they would begin piloting an autonomous vehicle ride-hailing service in Boston. Redzic said to market a self-driving service, regulations need to change to allow driverless cars on roads. At the moment, most global jurisdictions do not expressly authorise vehicles to operate on regular roads without a driver. "It doesn't just depend on us," he said. "To become fully driverless you need laws to change." Reporting by Naomi TajitsuRelated Video:

Nissan recovery to focus on U.S., Japan, China markets

Nissan will pull back from Europe and elsewhere to focus on the United States, China and Japan under a plan that represents a new strategic direction for the embattled carmaker, people with direct knowledge of the plan told Reuters. The "operational performance plan" is due to be announced on May 28 and goes beyond fixing problems from ousted leader Carlos Ghosn's aggressive expansion drive, the people said. The company's struggles predate the current global economic shutdown. Nissan's 2019 sales slumped severely.  Nissan was already planning to implement what was described as a "do or die" plan in January, before the global coronavirus pandemic froze automotive production and sales worldwide.  Pursuit of market share, particularly in the United States, led to steep discounting and a cheapened brand. Under the new, three-year plan — reported here for the first time — Nissan aims to restore dealer ties and refresh lineups to regain pricing power and profitability, the people told Reuters. "This is not just a cost-cutting plan. We're rationalizing operations, reprioritizing and refocusing our business to plant seeds for the future," one of the people said. The plan also aims to cut competition and expand cooperation with alliance partners, the people said. Nissan will follow Mitsubishi in plug-in electric hybrid vehicle technology, with the smaller peer taking the lead in Asian markets outside China and Japan. France's Renault will likely focus on electrical vehicle technologies and Europe. Nissan and Mitsubishi declined to comment. Renault did not immediately respond to a request for comment. The plan, led mainly by Chief Operating Officer Ashwani Gupta rather than Nissan's low-key chief executive, Makoto Uchida, is aimed at freeing resources to invest in products and technology for the United States, China and Japan, the people said. "The net effect is even though we reduce our R&D spend this year versus last year and make other savings, we pump those freed-up resources back into core markets and core products," said one of the people, who declined to be identified as they were not authorized to speak with media on the matter. The plan is likely to take up to two weeks to be finalized, with sales and earnings targets complicated by the anticipated long-term impact on auto sales of government measures worldwide taken to stop the coronavirus outbreak, the people said.
