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 expands US EV test market for e-NV200 to Portland

Of course, it's going to be Portland. Oregon's largest city, known for its green-friendly vibe and policies, will be where Nissan will next test of its all-electric e-NV200 cargo van. And we hope those vans have cup holders for the inevitable java. The Japanese automaker is working with local utility company Portland General Electric (PGE) on a six-week trial program. Nissan and PGE will record data to better measure how the concept of battery-powered driving works within the local services network. The location makes sense, as Portland is one of the five best-selling US cities when it comes to sales of the Nissan Leaf, which shares its powertrain with the e-NV200. Nissan kicked off its "No Charge to Charge" free-charging program for new Leaf owners in April. Nissan, which had already been testing the e-NV200 with FedEx in Germany, Japan and Singapore as of late last year, said at the Washington Auto Show in January that it would start testing the electric van in the Washington, DC, area. Nissan said at the time that it helped install about 570 fast-charging CHAdeMO chargers throughout the US since last year, including 200 in December alone. Check out Nissan's press release about the Portland project below. LEADING EV MARKET PORTLAND BECOMES TEST BED FOR NISSAN E-NV200 ELECTRIC COMMERCIAL VEHICLE PORTLAND, Ore. – Portland, already a top breeding ground for electric vehicle (EV) sales, is now the proving ground for Nissan's prototype electric commercial vehicle – the Nissan e-NV200. Nissan is working in collaboration with Portland General Electric (PGE) on a six-week trial to help determine the viability of an electric commercial vehicle in the U.S market. PGE has assigned the e-NV200 into its fleet of vehicles with an underground crew, replacing a larger, diesel-powered van. "Oregon has been a top five market for Nissan LEAF sales in the U.S. due to proactive policies at the state level to encourage EV adoption, as well as robust charging infrastructure championed by the state and others like PGE," said Toby Perry, Nissan's director of EV Marketing in the U.S. "If we determine that e-NV200 fits into the U.S. commercial vehicle market, we expect that Portland would be a leading driver for sales as well." This year, Nissan is deploying two e-NV200 prototypes with companies such as PGE and FedEx in top U.S EV markets including California, Georgia, Oregon and Washington, D.C.

Investigators say Mitsubishi mpg scandal was 'collective failure'

Investigators hired by Mitsubishi Motors to probe why the Japanese automaker engaged in falsifying fuel-economy figures for the past quarter-century faulted the company's "corporate culture." Specifically, there was a lack of unity between divisions, company-wide pressure to boost fuel-efficiency numbers, and an unwillingness to accept fuel-economy shortfalls, Automotive News says, citing comments made by consultants who hired by the company to investigate the problems. Challenging management authority even if it was proper to do so was also frowned upon. One of the investigators called the scandal "a collective failure." Among other suggestions, the consultants recommended that Mitsubishi's vehicle-mileage certification be independent from research and development, that there's greater transparency overall, and that there's a more thorough understanding of laws. New shareholder Nissan may also invest in retooling Mitsubishi's R&D operations, and is sending one of its former executives, Mitsuhiko Yamashita, to Mitsubishi to try to prevent any sort of repeat problems. Mitsubishi joined a list of automakers including Volkswagen, Hyundai/Kia, and Ford that have been found in recent years to either mislead with its published fuel-efficiency figures or emissions-testing procedures. A Nissan spokesman declined to comment on the Mitsubishi report, according to Automotive News. The recommendation comes less than three months after the announcement that Nissan would help rescue Mitsubishi from its fuel-economy scandal by acquiring part of the company. Nissan agreed in May to pay $2.2 billion for a 34-percent stake in Mitsubishi, and said at the time that Mitsubishi would join the Renault-Nissan Alliance. Nissan also owns 15 percent of France-based Renault. That announcement came right after Mitsubishi's admission that it may have falsified fuel-economy data for every one of its vehicles made in Japan dating back to 1991.
