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.

Porsche Taycan is here, Lamborghini Sian is near | Autoblog Podcast #594

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor Alex Kierstein and Senior Editor, Green, John Beltz Snyder. They start the conversation with the cars they've been driving, including the Subaru Forester, Lincoln Navigator, Mercedes-AMG C 43 and Subaru Crosstrek Hybrid. Then they talk about the biggest news of the week: the reveal of the all-electric Porsche Taycan. After that, they sweep up other news, like the Lamborghini Sian, new Nissan Juke and the Aston Martin Vanquish 25 by Ian Callum. Next, Autoblog's Erik Meier, who both produces this very podcast and also hosts our Twitch livestream, joins the chat with his impressions of the latest racing game, "WRC 8." Finally, our editors try to provide some helpful guidance in the "Spend My Money" segment.

Next Nissan GT-R to take cues from GT-R LM Nismo Le Mans entry

For those wondering why Nissan named its coming Le Mans Prototype the GT-R LM Nismo, colliding the two worlds of sports car and prototype racing, an article in Autocar might have the answer. The deeper union is explained by saying that the next-generation GT-R will use "hybrid technology that will closely align it" with the GT-R LM Nismo.
The point could be further driven home by the fact that the GT-R LM Nismo will begin its FIA endurance racing campaign next year, and the next GT-R is due to debut next year as a 2016 model. The expectation is that it will use a hybrid system possibly dubbed R-Hybrid and perhaps developed by Williams. Just like performance car makers Ferrari and Audi, Nissan wants its racing efforts to pay off with road car technology, company vice president Andy Palmer saying they "want to link technological linkages between future evolutions of the GT-R and evolutions of what we do in LMP1, and the two do go in both directions."
The bigger question is, with the GT-R getting hybrid assistance, will it also get the weight gain that usually comes with it? Enthusiasts would love to see the trend reversed, especially on a car that's already no lightweight.
