Tesla, BMW and Nissan meeting in secret to discuss charging tech

It's interesting what's happening in the electric vehicle field. It used to be that BMW and Tesla were competitors. Then – and of course they're still competing, especially in the public mind – they were working together on ... something. Maybe. And now, the Financial Times reports that the two luxury automakers are meeting with Nissan. Again, maybe. The scuttlebutt is that the three companies are interested in working together on something to do with charging electric vehicles, potentially a global recharging standard. Currently, when it comes to fast charging, BMW uses the SAE Combo standard, Nissan uses CHAdeMO and Tesla uses its own Superchargers. The meeting was prompted by Tesla opening of all of its patents the other day, FT says. Speaking during the recent annual shareholder meeting, Musk said he was "more than happy to have other manufacturers" use Tesla's Superchargers but that, "there is no other electric car that can accept anything close to 135 kilowatts." Let's assume the technical hurdle can be overcome. With any potential patent/licensing problems out of the way, these discussions with BMW and Nissan might be revolving around this other angle that Musk mentioned: "They (other automakers) just have to contribute to the capital cost, so figure out what percentage of the time are their cars using the Supercharger network and then they can make a contribution proportionate to their customer usage of the Supercharger network." That certainly sounds like something that could take some time to figure out.

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 sees its EV sales surging to 1 million annually by 2022

YOKOHAMA, Japan — Nissan announced plans to sell 1 million electric vehicles (EVs) annually by 2022, a six-fold jump from what it sold last year, and said it had no plans to stop testing its self-driving cars on public roads, calling them safe. Japan's No. 2 automaker and its rivals are planning to crank up development and production of electric cars in response to tightening emissions regulations around the world, even as demand for such vehicles remains limited due to their high cost and limited charging infrastructure. Launched as the world's first mass-market all-battery EV in 2010, Nissan's Leaf compact hatchback is the world's best-selling EV, though sales have been just around 300,000 units in its lifetime. The company now plans to focus its lower-emissions lineup on all-battery and gasoline-hybrid EVs rather than costlier technologies including plug-in hybrids. Nissan said on Friday it would develop eight new all-battery EVs over the next five years, including four models for China. Its luxury Infiniti brand would begin carrying new electric models from 2021, it added. Through 2022, vehicles powered by its "e-Power" gasoline-hybrid technology would likely comprise the majority of Nissan's electric line-up, it said. Such vehicles use gasoline to power the car's motor, requiring a much smaller battery than EVs and therefore are less expensive to produce. "The heart of our strategy in terms of electrification is battery EVs and e-Power technology," Nissan Chief Planning Officer Philippe Klein told reporters at a briefing. Concerns about EV battery costs and components have prompted many automakers to develop a variety of lower emissions technologies, but Klein said that Nissan would largely forego plug-in hybrids and hydrogen fuel cell technologies, given their low cost-performance at the moment. In 2017, Nissan sold 163,000 electric vehicles globally. Nissan and its automaking partners, Renault and Mitsubishi, together plan to launch 17 electric models as part of their strategy to achieve annual vehicle sales totaling 14 million units by 2022, compared with 10.6 million units in 2017. Self-driving tests to continue Automakers and technology companies are facing mounting pressure to prove that their automated driving functions under development are safe to use on public roads following a fatal accident involving a self-driving car operated by Uber Technologies [UBER.UL] in the United States earlier this week.
