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.

Alfa Romeo Giulia Quadrifoglio and Nissan 370Z 50th Anniversary | Autoblog Podcast #600

In this, the 600th episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder and Associate Editor Joel Stocksdale. They've been driving the Nissan 370Z 50th Anniversary edition, Alfa Romeo Quadrifoglio and Buick Enclave, and they're pretty excited about at least two of them. Then they talk about the Subaru Forester in their long-term garage. Finally, they spend a listener's money on a used car.

Nissan sells 100,000 Leaf EVs worldwide

Nissan sold 22,610 Leaf electric vehicles in the US last year, but the bigger story (literally) is how the company is selling the EV around the world. After selling the 99,999th Leaf to a woman in Virginia, Nissan sold the 100,000th Leaf to a man named Brett Garner in the UK. For the record, it took Nissan just about three years and one month to reach that mark, since the first Leafs were sold in December 2010. On a global scale, Nissan says the Leaf has a 45 percent market share among all the electric vehicles available. The car is available in 35 countries, but the bulk - as of the end of December, 42,122 units - have been sold in the US. That 99,999th Leaf was sold to Amy Eichenberger, a project manager overseeing major capital investments for the University of Virginia in Charlottesville (pictured below). Garner owns a dental practice in Fareham. You can read their gushing quotes about their new EVs in the Nissan press releases below. If you add in all of the electric vehicles that Nissan and partner Renault have sold (90,000 as of March, the last time official numbers were available), then the 100,000 was topped a while ago. Of course, electric vehicles remain a small portion of Nissan's global sales. In fiscal 2012, Nissan sold 4.9 million vehicles around the world. Still, 100,000 Leafs out of 4.9 million cars is far better than zero. Nissan LEAF global sales reach 100,000 units Nissan LEAF is best-selling EV in history with 45% market share The 100,000th customer is a British dentist After revolutionizing passenger vehicle segment Nissan is electrifying LCVs with the e-NV200 YOKOHAMA, Japan (January 20, 2014) – The 100,000th all-electric Nissan LEAF is being bought by a customer in the United Kingdom. The Nissan LEAF, the world's first mass-produced zero emissions vehicle, remains the best-selling EV in history with a 45% market share. Since its launch in December 2010 Nissan has seen the pace of sales increase consistently and 2013 was a record year. The LEAF is now available to customers in 35 countries on four continents. In Norway, the Nissan LEAF topped sales charts, out-selling conventional gasoline powered vehicles in October 2013. The 100,000th Nissan LEAF customer is Dr. Brett Garner, the owner of a dental practice in Fareham in the UK. "I have chosen my Nissan LEAF because I am very interested in its running costs," Dr. Garner said. "The cost of ownership such as maintenance, insurance and charging also convinced my wife.
