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.

Recharge Wrap-Up: Georgia lawyers love the Nissan Leaf, 2B vehicles by 2035

Loads of lawyers at a firm in Georgia are taking advantage of the state's EV tax credit. Georgia offers a tax credit on leases and purchases of electric vehicles for 20 percent of the car's value, up to $5,000. This has created a trend among lawyers at Arnall Golden Gregory, who one after another have been switching from gas-powered cars to the all-electric Nissan Leaf. They appreciate the environmental benefits, as well as toll exemption and access to HOV lanes, but the tax credit seems to be the biggest motivation to switch. Says lawyer Scott Wandstrat, "Everybody is signing up, now that all the cool kids are doing it." Read more at Daily Report. (Thanks to Kevin D. for the tip!) There's an easy way to see what kind of battery pack a Tesla Model S is using. Underneath the car on the passenger side, just behind the front wheel is a sticker on the outside of the battery pack. At the top is the battery size, 60 kWh or 85 kWh. Below that is a part number, followed by a letter. According to this Tesla Motors Club wiki, those numbers denote new or refurbished battery packs. The A, B or D following that number refers to the generation of battery, which also corresponds to charging capabilities. Knowing how to decode a Tesla pack could be useful if you ever need to replace your battery. Get more details at Teslarati. There will be 2 billion vehicles in use by 2035, according to a forecast by Navigant Research. The group who brought you the fuel consumption figures we shared with you previously estimates that there are currently almost 1.2 billion light-duty vehicles in use today. Navigant expects stop-start technology to grow, with 45 percent of vehicles on the road being equipped with it by 2035. Read more at Green Car Reports.

2014 Nissan Rogue

When I first started in this whole automotive journalism biz, I held a sort of hodgepodge receptionist/gopher/production assistant role, and each morning as the staff filed in, I'd ask them how they liked whatever car they were assigned to drive the previous night. Most of my colleagues would regale me with anecdotes about how good or bad a vehicle was, but one co-worker, every single morning, would answer my query with the exact same phrase: "It was fine."
I always assumed this was just a brush-off, an "ask me again after I've had a cup of coffee" sort of response. But then I found myself in a similar moment of brevity following the launch of the 2014 Nissan Rogue earlier this week. After returning home, a friend asked me what I thought of the new Rogue, and I replied, word for word, "It was fine."
And, well, it was. Nothing worth wasting exclamation points over, good or bad. Aside from something like the interesting-to-drive Mazda CX-5 or funky-looking Jeep Cherokee, nothing in this class really tries to set the world on fire. And that, right there, is fine. Nissan doesn't need to do anything crazy with its second-generation Rogue. It just needs to offer a well-equipped crossover that's handsome, functional, efficient and priced right - sticking to the same formula that made the first-generation model so successful while offering the latest crop of creature comforts in a more modern package.
