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.

2022 New York Auto Show, and Subaru Solterra driven | Autoblog Podcast #725

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder. This week was the return of the New York Auto Show, and it was a busy one. Our editors run down some of the reveals, including the updated Kia Telluride and Hyundai Palisade, the long-wheelbase Jeep Wagoneer and Grand Wagoneer L, refreshed Subaru Outback, the gorgeous Genesis X Speedium Coupe concept EV, the 2,200-horsepower Deus Vayanne electric hypercar, a new generation of the Kia Niro family, and the updated Nissan Leaf and Nissan Pathfinder Rock Creek. Then they discuss the news surrounding Elon Musk's offer to purchase Twitter before diving into reviews of the cars we've been driving, including the new Subaru Solterra, Subaru Forester Wilderness and our long-term BMW 330e xDrive and Hyundai Palisade.

Renault-Nissan zero-emissions car sales whir past 100,000 [w/video]

The electric vehicle has gone gold at Renault-Nissan, clocking 100,000 sales in a three-year period that began with the first Nissan Leaf being sold in Silicon Valley, California in 2010. Since then, the Leaf has become the EV champion of the world, selling more than 71,000 units so far, the majority of those in the US. The 100,000th EV sold by the Alliance was also a Leaf and also sold in the US, but on the other side of the country, in Georgia.
By comparison, Renault has sold 30,000 electric vehicles since late 2011, looking after other segments of the EV market with the Kangoo Z.E., Zoe, Twizy and Fluence Z.E. The alliance estimates that its efforts have been driven 5.2 million ion-powered miles and saved 14 million gallons of oil since they appeared. For a bit of sobering context, the US averaged 18.83 million barrels of oil per day in 2011, which is almost 791 million gallons. Per day.
So we're getting there, albeit slowly. Quietly. There's a press release and a video below with more details on the achievement.
