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 recalls over 120,000 Altimas due to... spare tire inflation?!

A pressure regulator that over- or underinflated spare tires for five days earlier this year has led to a recall of 123,308 units of the 2013 Nissan Altima. Sedans that were manufactured from March 21-26 are those possibly affected by the temporary tire snafu, the recall for which will begin on May 3.
Those notified of the issue can take their sedans to their local Nissan dealer, who will check the tire pressure and correct it if necessary, but we imagine owners can probably just whip out a tire gauge to check and adjust the inflation for themselves. Should you need it, there's an official notice from the National Highway Traffic Safety Administration below with a few more details.

Ghosn: Restoring Mitsubishi's reputation is biggest challenge

After news that Mitsubishi falsified its fuel economy data on every vehicle it has sold in Japan since 1991, and the tumble in the company's value that followed, the troubled carmaker has an unlikely savior. Nissan has confirmed it will purchase over one third of Mitsubishi's stock, or 34 percent. The stake is valued at $2.2 billion. Ghosn says making Mitsubishi a part of the Renault-Nissan alliance will save billions in development costs. But the merger certainly isn't without challenges. "The biggest challenge is to support Mitsubishi changing itself and growing and being profitable and restoring its reputation," said Ghosn. Nissan is a natural partner for Mitsubishi, and since the fuel economy scandal escalated from discrepancies in the data regarding Mitsubishi-manufactured, Nissan-badged Japan-market vehicles, it makes sense for the company to sweep in and save the day. Nissan itself is partially owned by Renault, and Nissan has a 15-percent stake in the French automaker. Mitsubishi's chairman, Osamu Masuko says that the merger was inevitable, that it "would have happened one day" anyway, according to the New York Times. Carlos Ghosn, chairman of both Nissan and Renault, is confident they will be able to turn Mitsubishi's fortunes around. "We have the track record to make it work", Ghosn said, referring to the Renault-funded rescue of Nissan in the early 2000s. Related Video:
