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.

Sunday Drive: Big debuts from the Big Apple dominated the headlines

New York Auto Show week has come and gone, and, not surprisingly, the week's biggest bits of news came from the halls of the Jacob K. Javits Convention Center in NYC. Our favorite debut from New York was the Lincoln Aviator, a sharp-dresses crossover that looks lovely inside and out, and sits on underpinnings at least partly derived from the Ford Mustang. While the Aviator may have caught our attention, it wasn't the most popular vehicle debut from New York, at least when judging by the number of page views here on Autoblog. That distinction goes to the 2019 Toyota RAV4, and we're hardly surprised. The RAV4 is the most popular compact crossover in America (in fact it's the most popular vehicle that isn't a pickup truck), and the 2019 version looks like a radical departure from the model that came before. We can't wait to drive the thing. Midsize sedans may not be the darling of the family car set, that honor taken over by the aforementioned crossover, but they still sell in large enough numbers that a brand-new model catches our attention. Such is the case with the 2019 Nissan Altima. We broke down the specs of the Altima and compared Nissan's bread-and-butter sedan with its biggest rivals. And finally, we got some official figures for the 2019 Ford Mustang Bullitt. It'll cost a cool $12,000 over the cost of a Mustang GT, and will benefit from a 480-horsepower, 420-pound-foot version of Ford's excellent 5.0-liter V8 engine. As always, stay tuned this week for all the latest automotive news that's fit to print. 2018 New York Auto Show Mega Photo Gallery | Start spreading the news 2019 Toyota RAV4 actually looks pretty cool 2019 Nissan Altima vs Honda Accord vs Toyota Camry: How they compare 2019 Mustang Bullitt orders open as Ford reveals price and horsepower Image Credit: Drew Angerer/Getty New York Auto Show Ford Lincoln Nissan Toyota Coupe Crossover SUV Sedan 2018 new york auto show

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.
