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.

Takata air bag recall list

The National Highway Traffic Safety Administration confirmed yesterday that 33.8 million vehicles with Takata airbags are going to be recalled. It's the largest recall in automotive history. The already record-breaking rate of automotive recalls this year shows no signs of slowing down, especially since millions of cars with defective airbags made by global supplier Takata are under ongoing scrutiny. The federal government is warning owners that inflator mechanisms in the air bags can rupture, causing metal fragments to fly out when the bags are deployed. The faulty air bags have already been blamed for multiple deaths. How do you know if your vehicle is safe? The National Highway Traffic Safety Administration released an updated list of vehicles under recall. Sometimes however, the government's website will crash and the list may not be complete. Check your VIN at the NHTSA website to make sure. The list of cars affected by the recall has not been released, but seem to span multiple models over the years for many of the automakers.

2013 Nissan Pathfinder: March 2013

Over the past few months, we've talked a lot about how our long-term 2013 Nissan Pathfinder functions as a daily-driver, long-hauler and all-weather warrior. And so far, it's earning high praise from most of us for being a well-rounded, pleasant vehicle in these regards. But the vast majority of people who actually go out and buy a Pathfinder will do so because of its people-and-stuff-carrying abilities. Nissan specifically engineered the new Pathfinder to be a softer, more widely appealing crossover than the sort of rugged SUV that it was before, and in doing so, the company is hoping its new CUV will find homes in the garages of many American families.
We needed to get some family impressions of the new Pathfinder, and fast.
Thing is, many of us Autobloggers live the kid-free life - at least that's true of most of us in the Detroit area where the Pathfinder currently resides. We have no doubts that the Pathfinder will get a proper family road trip workout from west coast editor Michael Harley after it shuffles over to the left side of the country, and it might also do a jaunt to North Carolina this summer with executive editor Chris Paukert and his family before it leaves the area, but in the meantime, we needed to get some family impressions of the new Pathfinder, and fast.
