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.

Renault-Nissan to build EVs in China with Dongfeng

BEIJING — Nissan and its partner Renault will build electric cars in China in a new venture with Dongfeng Motor, as global automakers scramble to get ready for stringent electric vehicle quotas being introduced by the nation. China, the world's biggest auto market, wants all-electric battery cars and plug-in hybrid vehicles to make up at least a fifth of the country's auto sales by 2025, as part of its solution to tackle alarming pollution levels in major cities. Ford announced earlier this month it was exploring setting up a joint venture with car maker Anhui Zotye Automobile Co to build electric vehicles in China under a new brand. Tesla, Daimler, Volkswagen and General Motors have already announced plans for making electric vehicles in China, The new joint venture, called eGT New Energy Automotive Co, will be owned 25 percent each by Nissan and Renault with Dongfeng owning 50 percent, Nissan and Renault said in a statement on Tuesday. They said eGT will design a new electric vehicle on a subcompact crossover SUV platform of the Renault-Nissan alliance. "The establishment of the new joint venture with Dongfeng confirms our common commitment to develop competitive electric vehicles for the Chinese market," Carlos Ghosn, chairman and chief executive officer of the Renault-Nissan alliance, said in the statement. The statement did not give details of financial commitments of the joint venture partners or say by when the vehicles will be launched. Dongfeng already partners Nissan in China. Both Nissan and Renault already market electric cars. Nissan's Leaf compact hatchback has become the world's top-selling electric car since its launch in 2010, while Renault began selling its Zoe model in 2012. The game changer for global automakers, many of whom until recently have resisted an industry shift to heavily electrified vehicles, is China, an auto market with strong potential for growth where stringent policies favoring cleaner energy cars are being aggressively pursued. Under China's latest proposals, electric vehicle sales quotas, which are expected to take effect as early as 2018, are due to require 8 percent of automakers' sales to be battery electric or plug-in hybrid vehicles by next year, rising to 10 percent in 2019 and 12 percent in 2020.

Ghosn: Low oil prices won't hurt EVs much

Carlos Ghosn might be the most unflappable automotive CEO around. Despite lower gas prices and signs that these prices do impact green vehicle sales, the CEO of the Renault-Nissan Alliance was at the World Economic Forum in Davos, Switzerland this weekend saying that people will continue to buy electric vehicles. "I don't think it is going to be slowing down," he said. "The people who are buying mainly for economic reasons may be deterred from it, but you have plenty of consumers buying EV for other reasons. On top of this, even though the price of oil is unpredictable – nobody has predicted last year that we would be at this level of oil price today and nobody knows where oil price will be next year or two years down the road – but what is predictable is that the regulation on emissions is going to get tougher in the various markets where we are present. So, our EV strategy is here not only to face too much dependence on oil or the cost of oil, but also to allow us to meet the very stringent regulations on emissions that are happening and will be happening in the future. So I can bet you that more and more car makers are coming to EVs and they're going to continue to build and sell EVs, even though the price of oil is coming down."
