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.

Ghosn hedges Nissan's 2020 autonomous deadline

Three years ago, Nissan was one of the first companies to promise a hands-free autonomous car by 2020. According Nissan Chairman and CEO Carlos Ghosn, when and how much we'll be able to take our hands off the wheel depends on more than just the components in the car. At a press conference during this year's Frankfurt Motor Show, the head of the Renault-Nissan Alliance said, "No matter how fast the technology develops, the autonomous cars are very dependent on the regulation." Basically Ghosn is saying that Nissan will be ready, but the laws allowing hands-free driving might not be so prompt. "You can build a lot of autonomy, but if the consumer or the driver cannot enjoy it because he still has to have his hands on the wheel, he still has to have his eyes on the road, it just puts cost in the car without the benefit," said Ghosn. The overall tone of Ghosn's comments was that Nissan is ready for autonomous driving, but without clear laws there could be no point in offering the technology to consumers. Ghosn also clarified what autonomous driving means in Nissan terms, clarifying a statement last year where he said a consumer product is still a long way off. The company's three-step plan begins next year, "where you can be on the highway as long as you don't change lanes and you can be in autonomous mode." Then in 2018, these systems will be able to change lanes without human intervention. For the final step in 2020, "We're going to have cars capable in the city and on the highway to make more complicated operations [in an] autonomous way," said Ghosn. "That's why I think when you talk about autonomous cars, we have to be much more specific about what kind of autonomy are we talking about... but we maintain our forecast that is going to come in different waves, and we define our waves by the functionality of autonomy in our cars [in] '16, '18, '20." That said, don't skip your driver's license renewal five years from now. According to Ghosn, you won't see a Nissan without a steering wheel. That's both Nissan's goal, and the company's way around the lack of regulation on driverless cars. "Frankly, a car without a driver is not our priority... There is a driver, and we are putting some functions into the car, allowing the driver to drive when they want, and to stop driving when they want... These are the same pieces of technology, which in addition to others, can lead you to the car without the driver.

Recharge Wrap-up: Car2go launches in Brooklyn, Green Fleet Car of the Year Award announced

The Car2go carsharing service is starting operations in Brooklyn next month. Beginning October 25, the service will offer 400 Car2go edition Smart Fortwo vehicles for point-to-point travel. Members pay a one-time sign-up fee, and are charged by the amount of time the use the vehicle (fuel and insurance is free).

Car2go is offering free membership and 30 minutes of credit for those who sign up early with a special promotional code. Learn more in the press release below. Renault and the Eco2charge consortium are working to bring better EV charging to France. They are providing research and development aimed at turning simple charging stations into "fully fledged energy ecosystems" through a smart grid. This grid would coordinate charging, consumption and energy storage in a way that increases efficiency and decreases cost. Read more in the press release below. The Renault-Nissan Alliance could source EV batteries from suppliers other than Nissan, according to CEO Carlos Ghosn. This news comes after recent questions of whether or not Nissan would scale back battery production in the US and UK. Ghosn says, "At the moment, we continue to produce our own batteries and we are open to outside sourcing, period." He also denies any plans to shutter Nissan's battery production facility in Tennessee. One source of batteries the alliance will look to is Korea's LG Chem. Read more at Automotive News Europe. The first-ever Green Fleet Car and Truck of the Year Awards will be presented at the Los Angeles Auto Show. The presentation on November 20 will be part of the LA show's Connected Car Expo. Nominees are selected by Bobit Business Media, with finalists picked by readers of Green Fleet, Automotive Fleet, Work Truck and Business Fleet magazines. The winners will be chosen based on performance, fuel economy, emissions, safety, capacities and other similar factors.
