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 ZEOD RC finds nothing but trouble at 2014 Le Mans

Audi came away a big winner at this year's Le Mans competition, but Nissan has at least one thing to celebrate. The Pyrrhic victory apparently presages Nissan giving up on the gas-electric race car for Le Mans 2015. Before the race this weekend, the prototype ZEOD RC hybrid race car was doing quite well. In fact, given the way things turned out, Nissan's keen to mention that team engineers managed to get the car to complete a lap on electric power and hit a target speed of 300 kilometers per hour (186 miles per hour) on the Mulsanne Straight during testing. ZEOD RC stands for Zero Emission On Demand Racing Car. "The race was obviously very disappointing" – Wolfgang Reip Things didn't go so well once the real race started. The problem for the Deltawing-esque prototype – which is powered by a 1.5-liter gas ending putting out 400 horsepower and a pair of 110-kW electric motors – was that something broke in the transmission after just 23 minutes and five laps. Driver Wolfgang Reip put his best spin on the hybrid's collapse: "The race was obviously very disappointing but having got a taste of Le Mans now, I can't wait to get back." If Reip does return with Nissan, it will likely be in a more traditional Le Mons racer. The ZEOD RC was part of the LM P2 class, but Nissan says that, "For Le Mans 2015, Nissan will return to the LM P1 class." You can watch the full warm-up electric lap in a video below.

Nissan ZEOD RC heroic electric lap followed by heartbreak Amazing morning warm-up result after all-nighter by crew "New tech" car halted by "old tech" issue Nissan breaks new ground in electric vehicles LE MANS, France – Nissan's assault on the Le Mans 24 Hours may have ended early, but the revolutionary Nissan ZEOD RC electric prototype still leaves Le Mans having reached its historic goals of hitting 300 km/h on the Mulsanne Straight and recording a complete lap of Le Mans on electric power only. The unique prototype – which features both internal combustion and electric power sources – reached its first target during Thursday night qualifying when Satoshi Motoyama exceeded 300 km/h before the first chicane on the Mulsanne Straight. Nissan's other key goal was to complete an entire 8.5-mile lap of Le Mans on pure electric power. GT Academy winner Wolfgang Reip was at the wheel when the team achieved this goal during the morning warm-up.

Strains between France and Italy risk Renault-FCA merger

PARIS/ROME — Fiat Chrysler's proposed $35 billion merger with Renault has cheered investors, won conditional support from Paris and Rome and even earned cautious backing from trade unions. Beneath this veneer, however, the bold attempt to create the world's third-largest carmaker risks becoming rapidly embroiled in the fraught relationship between France's europhile President Emmanuel Macron and Italy's euroskeptic leaders. For while Deputy Prime Minister Matteo Salvini hailed the proposal as a "brilliant operation," Italy's creaking, state-subsidized Fiat factories are likely to bear the brunt of any production-related cost savings. FCA and Renault said this week that more than 5 billion euros ($5.6 billion) of annual savings would come mainly from combining platforms, consolidating powertrain and electrification investments and the benefits of increased scale. Salvini and France's Finance Minister Bruno Le Maire, who called the deal a "good opportunity" to build a European industrial champion able to compete with China and the United States, have both said they want guarantees on local jobs. "It's not every day that I agree with Salvini," said Le Maire, whose government appears to hold the trump cards. When it comes to where any job cuts fall, France will be helped by its existing 15 percent holding in Renault, whose superior efficiency at its five French plants makes it better placed to handle a supply glut, the demise of the petrol engine and the investments needed for electric and autonomous vehicles. "It will take many, many years to find real savings, and ugly political and operational realities can often swamp the potential of such new entities," Bernstein analyst Max Warburton said of the FCA-Renault plan to rival Japan's Toyota and Germany's Volkswagen. Advantage France? As well as Italy's government having to cope with the aftermath of European elections, which coincided with news of the FCA-Renault plans, political leaders in Rome were only informed shortly before the deal was made public, an FCA source said. This contrasted with the way the French government was treated, with Fiat Chrysler Chairman John Elkann, a fluent French speaker, letting it know of his merger proposal to Renault weeks ago, a French government official said.
