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.

Recharge Wrap-Up: Georgia lawyers love the Nissan Leaf, 2B vehicles by 2035

Loads of lawyers at a firm in Georgia are taking advantage of the state's EV tax credit. Georgia offers a tax credit on leases and purchases of electric vehicles for 20 percent of the car's value, up to $5,000. This has created a trend among lawyers at Arnall Golden Gregory, who one after another have been switching from gas-powered cars to the all-electric Nissan Leaf. They appreciate the environmental benefits, as well as toll exemption and access to HOV lanes, but the tax credit seems to be the biggest motivation to switch. Says lawyer Scott Wandstrat, "Everybody is signing up, now that all the cool kids are doing it." Read more at Daily Report. (Thanks to Kevin D. for the tip!) There's an easy way to see what kind of battery pack a Tesla Model S is using. Underneath the car on the passenger side, just behind the front wheel is a sticker on the outside of the battery pack. At the top is the battery size, 60 kWh or 85 kWh. Below that is a part number, followed by a letter. According to this Tesla Motors Club wiki, those numbers denote new or refurbished battery packs. The A, B or D following that number refers to the generation of battery, which also corresponds to charging capabilities. Knowing how to decode a Tesla pack could be useful if you ever need to replace your battery. Get more details at Teslarati. There will be 2 billion vehicles in use by 2035, according to a forecast by Navigant Research. The group who brought you the fuel consumption figures we shared with you previously estimates that there are currently almost 1.2 billion light-duty vehicles in use today. Navigant expects stop-start technology to grow, with 45 percent of vehicles on the road being equipped with it by 2035. Read more at Green Car Reports.

Spitballs flying between Nissan and Fiat

At the 2012 LA Auto Show, Fiat brand chief and recently crowned marketing genius, Olivier François, attempted to distance the Fiat 500e from other electric vehicles, asking rhetorically, "Isn't ugliness the worst kind of pollution?" Nissan has apparently taken issue with these comments, feeling slighted for what it considers digs at the Leaf's styling. In a recent interview with Automotive News, Nissan's marketing chief Simon Sproule shot back, "Let's face it, Fiat has not shied away from controversial styling themselves," he continued, "many would describe many of their products as visual pollution." Ouch.
Sproule says that while the 500e is a "me-too" product, made only to appease US emissions regulations, the Leaf is a serious effort at producing an EV. The Nissan marketing boss points out that the Japanese automaker has invested billions in EV development and production facilities, while Fiat will lose $10,000 on every 500e sold.
However sales of the Leaf in the US are down five percent. Nissan sold just 8,330 Leaf's so far this year, but Sproule contends that it has less to do with styling, and more with the charging infrastructure. Sproule also thinks that Nissan hit a balance between styling and practicality with the Leaf: "It's still very recognizable as a five-seat hatchback, fully functioning, absolutely competitive with the packaging of the Golf of any other mainstream vehicle." For a segment where efficiency is king, isn't that what matters most?
