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 and Nissan are among the businesses affected by massive ransomeware attack

SINGAPORE/TORONTO, May 14 (Reuters) - Technical staff scrambled on Sunday to patch computers and restore infected ones, amid fears that the ransomware worm that stopped car factories, hospitals, shops and schools could wreak fresh havoc on Monday when employees log back on. Cybersecurity experts said the spread of the virus dubbed WannaCry - "ransomware" which locked up more than 200,000 computers - had slowed, but the respite might only be brief. New versions of the worm are expected, they said, and the extent of the damage from Friday's attack remains unclear. Infected computers appear to largely be out-of-date devices that organizations deemed not worth the price of upgrading or, in some cases, machines involved in manufacturing or hospital functions that proved too difficult to patch without possibly disrupting crucial operations, security experts said. Marin Ivezic, cybersecurity partner at PwC, said that some clients had been "working around the clock since the story broke" to restore systems and install software updates, or patches, or restore systems from backups. Microsoft released patches last month and on Friday to fix a vulnerability that allowed the worm to spread across networks, a rare and powerful feature that caused infections to surge on Friday. Code for exploiting that bug, which is known as "Eternal Blue," was released on the internet in March by a hacking group known as the Shadow Brokers. The group claimed it was stolen from a repository of National Security Agency hacking tools. The agency has not responded to requests for comment. Hong Kong-based Ivezic said that the ransomware was forcing some more "mature" clients affected by the worm to abandon their usual cautious testing of patches "to do unscheduled downtime and urgent patching, which is causing some inconvenience." He declined to identify which clients had been affected. The head of the European Union police agency said on Sunday the cyber assault hit 200,000 victims in at least 150 countries and that number will grow when people return to work on Monday. "The global reach is unprecedented ... and those victims, many of those will be businesses, including large corporations," Europol Director Rob Wainwright told Britain's ITV. "At the moment, we are in the face of an escalating threat. The numbers are going up, I am worried about how the numbers will continue to grow when people go to work and turn (on) their machines on Monday morning." MONDAY MORNING RUSH?

Nissan sets 2017 sales record with help from Rogue, Titan, and Armada

Nissan Group said its U.S. sales climbed 1.9 percent in 2017 to an all-time record of more than 1.59 million vehicles sold. Free pizza in the conference rooms in Nashville, right? But a closer look shows the company mirroring overall industry trends, with plenty of declining-popularity cars but also a few aging trucks and SUVs. Taken together, Nissan's trucks, SUVs and crossovers saved the day, selling an all-time high of 765,624 total units, up 15 percent from 2016. That offset a 10.9-percent drop in sales of Nissan's cars, as volume sellers like the Altima and Versa posted steep drops. Also buoying overall results was the Infiniti division, which gained 10 percent from the previous year on the strength of models like the Q60 and QX30. Nissan's record year owes a lot to the Rogue, its compact crossover, which set an annual sales record with 403,465 vehicles, an increase of 22.3 percent. Sales of the Titan, Nissan's full-size pickup, grew an impressive 141.9 percent to 52,924 units, while the Armada, a full-size three-row SUV that was all-new for 2017, also saw a huge jump in sales (154.1 percent) to 35,667. Infiniti, meanwhile, saw overall sales climb 10.9 percent on the strength of huge gains by the Q60 Coupe, which rose 170.8 percent, and the QX30 crossover, which grew almost 524 percent. That being said, Infiniti volume is relatively low. The Q60 Coupe sold a total of 40,444 units and the QX30 14,093 for 2017, while Nissan shifted 40,172 Rogues in December alone. On the car side, the Maxima did well, gaining 7.9 percent to finish at 67,627. Volume-wise, the Sentra dominated, nudging up 1.7 percent to 218,451. But the rest of the lineup mirrored industry trends for the car segment, with steep drops for the Altima (down 17 percent), battery-electric Leaf (-19.8 percent), Versa (-19.2 percent) and Juke (-48.1 percent). Several truck, crossover and SUV models are also not faring so well. The aging Frontier pickup, last updated in 2005, fell 14.5 percent, the Pathfinder slipped by 0.8 percent, the Quest minivan plummeted 55.5 percent and the upscale Murano crossover fell by 11.8 percent. A Nissan spokesman says the Quest is no longer being built for the U.S. market starting with the 2018 model year. Meanwhile, reinforcements are coming. Nissan has said it's planning a new generation of the Frontier, its entry-level pickup, but hasn't clarified when.
