DC fast charging not as damaging to EV batteries as expected

As convenient as DC fast charging is, there have been lots of warnings that repeated dumping of so many electrons into an electric vehicle's battery pack in such a short time would reduce the battery's life. While everyone agrees that DC fast charging does have some effect on battery life, it may not be as bad as previously expected. Over on SimanaitisSays, Dennis Simanaitis, writes about a recent presentation by Matt Shirk of the Idaho National Laboratory (INL) called DC Fast, Wireless, And Conductive Charging Evaluation Projects (PDF) that describes an ongoing test of four 2012 Nissan Leaf EVs that are being charged in two pairs of two. One pair only recharges from 50-kW DC fast chargers, which the other two sip from 3.3-kW Level 2 chargers exclusively. Otherwise, the cars are operated pretty much the same: climate is automatically set to 72 degrees, are driven on public roads around Phoenix, AZ and have the same set of dedicated drivers is rotated through the four cars. "Degradation depends more on the miles traveled than on the nature of recharging." What's most interesting are the charts on page seven of Shirk's presentation (click the image above to enlarge), which show the energy capacity of each of the four vehicles. When they were new, the four batteries were each tested to measure their energy capacity and given a 0 capacity loss baseline. They were then tested at 10,000, 20,000, 30,000 and 40,000 miles, and at each point, the DC-only EVs had roughly the same amount of battery loss as the Level 2 test subjects. The DC cars did lose a bit more at each test, but only around a 25-percent overall loss after 40k, compared to 23 percent for the Level 2 cars. Simanaitis' takeaway is that, "INL data suggest that the amount of degradation depends more on the miles traveled than on the nature of recharging." The tests are part of the INLs' Advanced Vehicle Testing Activity work and a final report is forthcoming. These initial numbers from IPL do mesh with other research into DC fast charging, though. Mitsubishi said daily fast charging wouldn't really hurt the battery in the i-MiEV and MIT tests of a Fisker Karma battery showed just 10-percent loss over 1,500 rapid charge-discharge cycles.

Nissan Friend-Me Concept is cooler than its name

Here is the Nissan Friend-Me, a swoopy - and let us emphasize that word "swoopy" - sedan-with-a-hatchback developed specifically for Chinese youth in their mid-twenties, the ones born in the '80s mainly bereft of siblings due to China's one-child policy. The exterior is meant to be most imposing at night, when Nissan figures these single children will be getting together with their friends. The sheetmetal looks like it was shaped by waves, and the details like lighting and vent openings could have been penned on Krypton.
The real show is inside, where peers are made equal and can interact with one another via the "oracle stone." The concept is that instead of a driver and three passengers, everyone gets access to the same information and the ability to alter the ambiance of the car - dash readouts are provided for all of the occupants, and anyone can move content from their phones to the in-car screens to be shared throughout. As Nissan says, it's the end of anyone being a "music dictator."
Designed by Nissan Design China for a specific market-within-a-market estimated to contain 240 million potential buyers, Nissan says the wishes of these customers and the ideas in this car could shape automotive offerings for decades to come. So read all about it in the press release below and take some long virtual looks in the galleries of high-res photos.

FCA-Renault merger talks: France wants job guarantees and Nissan on board

PARIS — France will seek protection of local jobs and other guarantees in exchange for supporting a merger between carmakers Renault and Fiat Chrysler, its finance minister said on Tuesday, underscoring the challenges facing the plan. Renault Chairman Jean-Dominique Senard arrived in Japan to discuss the proposed tie-up with the French company's existing partner Nissan — another potential obstacle to the $35 billion-plus merger of equals. Renault and Italian-American rival Fiat Chrysler Automobiles (FCA) are in talks to tackle the costs of far-reaching technological and regulatory changes by creating the world's third-biggest automaker. Nissan found out about Renault's merger talks with Fiat Chrysler only days before they became public, four sources told Reuters, stoking fears at the Japanese carmaker that a deal could further weaken its position in a 20-year alliance with Renault. A deal between Renault and FCA would create a player ranked behind only Japan's Toyota and Germany's Volkswagen and target 5 billion euros ($5.6 billion) a year in savings. Some analysts, however, say the companies face a challenge to win over powerful stakeholders ranging from the French and Italian governments to trade unions and Nissan. Patrick Pelata, a former Renault chief operating officer, also criticized the deal plan for undervaluing Renault and threatening to overstretch its engineering resources. By valuing Renault at its market price, the all-share offer attributes a negative 6 billion euro value to Renault operations after deduction of its 43.4% stake in Nissan and 3.1% Daimler holding, Pelata told BFM radio. "That's hardly reasonable," he said. "And I think that shareholders, including the French state, are bound to take issue with this sooner or later." Pelata added: "FCA has big problem because they haven't invested for the future — they have no electric vehicle platform and they've done nothing in autonomous cars." French finance minister Bruno Le Maire told RTL radio on Tuesday that the plan was a good opportunity for both Renault and the European car industry, which has been struggling for years with overcapacity and subdued demand. France sets conditions Le Maire also said the French government would seek four guarantees in exchange for backing a deal that would reduce its 15% stake in Renault to 7.5% of the combined entity. "The first: industrial jobs and industrial sites.
