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.

Caddy XT4, Subaru STI Type RA, and blazin' Elon | Autoblog Podcast #553

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor Alex Kierstein and Green Editor John Snyder. We talk about time spent with the Cadillac XT4 and Subaru WRX STI Type RA. Then we get into other topics, including the death of the VW Beetle, our thoughts on the state of the Nissan 370Z, cameras replacing mirrors, the trouble with the Ford Focus Active, and Elon Musk blazing a fat blunt. We indulge in a little conversation about the process of writing about cars. Finally we help a listener choose their next EV in the "Spend My Money" segment.Autoblog Podcast #553 Get The Podcast iTunes – Subscribe to the Autoblog Podcast in iTunes RSS – Add the Autoblog Podcast feed to your RSS aggregator MP3 – Download the MP3 directly Rundown Cars we've driven: Cadillac XT4 and Subaru WRX STI Type RA RIP, VW Bug What's up with the Nissan 370Z?

2015 Nissan Murano configurator is lux'd and loaded

We just got done driving the all-new, 2015 Nissan Murano and while you'll have to wait just a few more hours for our complete driving impressions, you can at least get online and build your very own example of Nissan's latest CUV, thanks to the company's new configurator. While Nissan has already published the Murano's starting price, this is our first glimpse at the full pricing details. As we said, prices start at $29,650, not counting an $885 destination charge. From there, things, um, increase. Moving from the base S to the mid-level SV will require an extra $3,060, and adds navigation with the NissanConnect telematics system, a power driver's seat, LED running lights, remote start and a USB port for backseat passengers. An additional $4,330 moves you up to the Murano SL, adding heated leather seats, a Bose stereo, AroundView monitoring, an auto-dimming rear-view mirror, a power liftgate and blind-spot monitoring with cross-traffic alert. At the top of the range sits the Platinum, starting at $39,000 ($2,050 more than the SL). It includes 20-inch wheels, LED headlights, climate-controlled front seats, heated rear seats and a heated steering wheel. Regardless of trim, Nissan customers will get about with the help of a 3.5-liter V6 that's been mated up to an Xtronic continuously variable transmission. Adding the optional all-wheel-drive system will bump up the CUV's price an additional $1,600. Head over to the configurator and build your own ideal Murano.
