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.

Mitsubishi to join alliance with Honda and Nissan, Nikkei reports

TOKYO — Japan's Mitsubishi Motors is set to join an alliance between Honda Motor and Nissan Motor, creating a tie-up between automakers with combined sales of more than 8 million vehicles, the Nikkei newspaper said on Sunday. Mitsubishi Motors, which is 34% owned by Nissan, will work with Honda and Nissan to finalize the details of their strategic partnership, Nikkei said, adding the three firms intend to standardize in-vehicle software that controls cars. Mitsubishi Motors declined to comment on the report, while a Nissan spokesperson would only say the report was not based on something either of the companies had announced. Spokespeople for Honda did not respond to a request for comment. The push comes as Nissan, Japan's third biggest automaker, has been steadily losing market share in its two largest markets, the United States and China, which together accounted for half of its global sales in the year to March. On Thursday, the company slashed its annual outlook after heavy discounting in the U.S. almost completely wiped out its first-quarter profit. Nissan and Honda said in March they were considering a strategic partnership to collaborate on producing electric vehicle components and artificial intelligence in automotive software platforms. Mitsubishi Motors is already part of a long-standing alliance with Nissan and France's Renault that the three automakers last year agreed to restructure, aiming for a downsized but more pragmatic and agile partnership. Separate collaboration between Nissan, Honda and Mitsubishi Motors could help Japan's automakers cut costs and beef up to battle tough competition in EVs, dominated by companies like China's BYD and Tesla. In China, the world's largest auto market, Japanese brands previously were strong but are now up against domestic automakers that have rapidly increased production and won over consumers with low-priced vehicles loaded with software.

Nissan unveils ZEOD RC at Nismo HQ in Japan [w/videos]

At Le Mans this past summer, Nissan unveiled the first prototype for the ZEOD RC, a new hybrid racecar which it intends to field at the famous French endurance race next year. Four months have passed since then, totaling eight month of development, and now Nissan has revealed the final form at the headquarters of its Nismo racing division.
The updated Nissan ZEOD RC benefits from a more streamlined shape with optimized cooling and improved aerodynamics. Although billed as an electric vehicle and not a hybrid, the ZEOD RC pairs a 1.6-liter turbo four with a pair of electric motors. Its regenerative braking system is derived from the Leaf RC, and after 11 laps, it's said to be capable of taking another around the Circuit de la Sarthe under electric power alone, making it the first racecar capable of doing so. Nissan has further stated that it hopes the lessons it garners from this project will help in its development of a new LMP1 to challenge for overall victory at Le Mans in the near future.
The ZEOD RC will be on display at Fuji Speedway this weekend during the six-hour FIA World Endurance Championship race there, after which it will continue its development at the hands of former GT1 champion Michael Krumm and gamer-turned-racer Lucas Ordonez, who will be getting it ready for (and possibly drive it at) next year's 24 Hours of Le Mans. There it will compete - faster than most GTE sportscars, says Nissan - in the Garage 56 spot that once was awarded to the DeltaWing, which Nissan sponsored and to which the ZEOD RC looks conspicuously similar.
