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.

Why 2015 is going to be a huge year for trucks

Nissan chief executive Carlos Ghosn took center stage to introduce the 2016 Titan last week at the Detroit Auto Show. He spoke of the truck's new features, impressive Cummins V8 diesel engine and the extensive amount of time and money required to build a modern, competitive pickup truck. "We have done all of this because we see opportunity – an opportunity in the unmet needs of today's American truck customers," Ghosn said. He was speaking about the Titan, but his thoughts echo the industry's mindset: When it comes to trucks, find an opportunity and attack. Even with CAFE regulations looming and fickle consumer preferences, investing in trucks is a no-brainer for automakers. Some consumers will always need a truck for their job or lifestyle. And some people will always want one, whether they need it or not. With that in mind, here are four reasons why the pickup-truck sector is more important than ever and poised for growth in 2015. View 24 Photos The Nissan Titan Is Back Okay, it never left, but the Titan hadn't been redesigned since its launch in 2003, and Nissan sold more NV200s than Titans in 2014. It's an understatement to say the truck was languishing. That all changes with the 2016 model. The Titan will come in two variants, a traditional fullsize competitor and the Titan XD. The XD will lead the market launch, and it arrives late this year. It's pitched as a "whitespace" offering, Nissan sales and marketing vice president Fred Diaz said. The idea is to offer something in the general size and price range of a fullsize truck, but also have some of the capability of a heavy-duty truck. The XD uses a fully boxed ladder frame, the chassis design from Nissan's commercial division, and the wheelbase is about 20 inches longer than other Titan models. The XD, which Nissan is calling the flagship of the line, will be the only model with the 5.0-liter Cummins turbodiesel V8. It produces 310 horsepower and 555 pound-feet of torque, while being able to tow 12,000 pounds. V6 and V8 gasoline models will also be offered on the Titan XD and the standard, non-XD model. When production ramps up, the Titan will be sold with several cabs, beds and trims. New features include trailer sway control, an integrated trailer brake controller, more storage options in the cabin and even laminated front and rear side glass to reduce outside noise. All of this has given Nissan fresh confidence in an area where it admittedly has been lacking. "We can compete," Diaz told Autoblog.

2022 New York Auto Show Roundup | All the reveals, reviews, pictures

NEW YORK — In case you missed it, the New York Auto Show took place this year after being canceled in both 2020 and 2021 due to Covid. A lot of manufacturers showed up in force, but not everybody did. No matter, we were there, and we brought you news, photos and scoops from the floor throughout the show. All of our New York-related stories can be found at our central hub here, but if youÂ’d rather just get a small taste of everything in a quick and digestible format, keep scrolling. 2023 Kia Telluride and its new X-Pro trim Kia revealed the TellurideÂ’s first major refresh at New York, and it makes the three-row crossover a little bit more desirable without screwing up what we liked about it before. ThereÂ’s a new X-Line and X-Pro trim for someone who might want a little more off-road capability, and a number of tech improvements. Most notably, a newly-designed dash features new and bigger screens. 2023 Hyundai Palisade The TellurideÂ’s sister car from Hyundai was treated to a similar refresh. Like the Telluride, Hyundai gave the Palisade a slightly revised look, a new off-road trim (called XRT in the PalisadeÂ’s case), more tech inside and a new dash design with full-width air vents. If we had to choose, weÂ’re a little more impressed with the TellurideÂ’s refresh, as a number of us on staff actually prefer the pre-refresh Palisade styling over the new one. 2023 Jeep Wagoneer L and Grand Wagoneer L This one was inevitable. Jeep revealed the longer, roomier versions of its Wagoneer and Grand Wagoneer in New York, and theyÂ’re designated with an “L” at the end of their names. Total length grows by a foot, and the wheelbase goes up by 7 inches versus the standard Wagoneer models. Jeep has essentially allocated all this extra room to the cargo area, as it now offers a staggering 44.2 cubic-feet of space behind the third row. Besides the L, Jeep announced that its new Hurricane inline-six engine would find its first home in the Wagoneer. Efficiency gets a small boost, and power is more than sufficient at either 420 horsepower (standard output) or 510 horsepower (high-output version) from the twin-turbo I-6. Chrysler Airflow Graphite Concept The Stellantis party continues with Chrysler and its slightly revised Airflow. Re-styled for the New York market after initially debuting at CES in Las Vegas, the Airflow Concept gets new paint, changed accent colors, a slightly changed interior design and a new interpretation of the Chrysler logo.
