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:

IIHS gives good ratings to 4 of 8 midsize pickups in crash test

Versions of the Toyota Tacoma, Chevrolet Colorado and GMC Canyon Crew Cab earned top ratings in a new crash test of midsize pickup trucks from the Insurance Institute for Highway Safety, while two versions of the Nissan Frontier earned marginal ratings. But the organization gave poor marks to all eight pickups tested for their dim headlights. Overall, four of the eight pickups evaluated earned good ratings for protecting occupants in all five crash test categories — the Tacoma double cab along with crew cab versions of the Colorado, Canyon and Tacoma. But the poor headlights and lack of an automatic emergency braking system blocked any of the pickups from qualifying for the IIHS's Top Safety Pick awards. The study looked at two pickup body styles using 2017 models: crew cabs, which have four full doors and two full rows of seating, and extended cabs, which have two full front doors, two smaller rear doors and compact second-row seats. It subjected each to five tests, and it evaluated the performance of front crash prevention systems and headlights. The Toyota Tacoma crew cab was the only pickup in that class that earned a good rating for structure in the small overlap test, which replicates what happens when a vehicle clips a tree, pole or another vehicle that has crossed the center line. The model's Access Cab extended-cab version was rated similarly, though its structure was rated acceptable. "This group of small pickups performed better in the small overlap front test than many of their larger pickup cousins," says David Zuby, the Institute's executive vice president and chief research officer. "The exception was the Nissan Frontier, which hasn't had a structural redesign since the 2005 model year." The extended-cab versions of the Chevy Colorado and GMC Canyon earned acceptable ratings, while both the Nissan Frontier king-cab and crew-cab models were rated marginal. Toyota says its 2018 Tacoma will feature upgraded headlights and a standard autobraking system that can detect pedestrians. "Headlights are basic but vital safety equipment. Drivers shouldn't have to give up the ability to see the road at night when they choose a small pickup," Zuby said.
