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.

Driving the Lincoln Aviator and flogging Abarths at Laguna Seca | Autoblog Podcast #593

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by West Coast Editor James Riswick and Associate Editor Joel Stocksdale. To begin, Greg takes a moment to remember the fastest woman on four wheels and former host of Autoblog's "The List," Jessi Combs, who died this week. Then our editors turn their attention to the cars they've been driving, including the Lincoln Aviator, Ford Ranger and Nissan Frontier, as well as Joel's recent stint in the Fiat 500 Abarth and Fiat 124 Spider Abarth, including track time at Laguna Seca. Finally, they turn their attention to a listener in Germany who is looking to replace an aging Volkswagen Eos with a newer convertible in this week's "Spend My Money" segment.

Nissan breaks annual EV sales record with two months to spare

Nissan has sold more pure EVs in the US this year than any other automaker, ever. And there are still two selling months left. Last year, Nissan sold a record 22,610 Leaf electric vehicles in the US. This year, through the end of September, Nissan sold 21,822 Leafs and has been selling more than 2,000 a month for the last seven months (in some cases, over 3,000). Basic math skills make it clear that 2014 would handily beat 2013, so now we get to play the guessing game to figure out by how much. Nissan isn't yet saying what October sales were (the month isn't over yet, and we're expecting the numbers on Monday) but if we look up the general trend for the last quarter of 2013, sales stayed steady (compared to the previous months) in October and November and then shot up in December. Given the overall increase in 2014 versus 2013 (up 36 percent through the end of September), who wants to bet that Nissan will sell more than 30,000 Leafs this year? Anyone? Compare Leaf sales with the other plug-in vehicle that went on sale alongside the Leaf at the end of 2010: the Chevy Volt sold over 23,000 units in 2012 and 2013 but is way down so far this year (14,540 through the end of September). An updated Volt will go on sale in the second half of 2015. Nissan has not disclosed when a new Leaf will go on sale. Nissan has sold over 142,000 first-gen Leafs around the world and over 64,000 in the US. Nissan LEAF sets annual U.S. electric vehicle sales record - again NASHVILLE, Tenn. – With more than two months remaining, Nissan LEAF has shattered the record for the most U.S. electric vehicle sales in a single calendar year, surpassing the previous record of 22,610 that it set in 2013. "With nearly 20 electric cars or plug-in hybrid models on the road today, Nissan LEAF remains at the head of the class, outselling the nearest competitor by 50 percent through September," said Brendan Jones, director, Nissan electric vehicle Sales and Infrastructure. "Since the initial launch in 2010 our primary goal is to bring electric vehicles to the mass market in a practical and fun-to-drive package, and we continue to deliver electric cars to more new buyers than anyone else." LEAF sales in 2014 through September are up more than 36 percent compared to the same period last year. With more than 142,000 LEAF sales globally since launch and more than 64,000 of those in the U.S., Nissan is the global leader in electric vehicles.
