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.

Nissan to make 85% of the vehicles it sells here in US

We could be in for a big push from Nissan in the manufacturing realm if Vice President of US Sales and Marketing Fred Diaz has anything to say about it. Speaking to the Automotive Press Association recently, Diaz (above) expressed a desire to build some 85 percent of the vehicles Nissan sells to Americans in the US, claiming it will happen "in the very near future." Nissan has already moved to increase exports of its US-built products, and in 2013, it built just over 76 percent of the models it sold in this market within our country's borders.
"Any issues of us taking advantage of the value of the yen, we want to dispel that," Diaz told reporters, pointing out the contentious issue of currency manipulation. There's also the obvious goal of positive PR - Americans like things made in America, and they like companies that invest in America. Diaz is quick to point out that Nissan had done just that: "While a lot of people retrenched [during the recession], instead we leaned into it and we continued investing and in fact made over $5 billion in investments, bringing a lot of production from Japan to the United States and to Mexico," Diaz said, pointing out that Nissan has helped create 8,000 jobs through its investments.
Nissan runs three factories in the US, two in Tennessee and one in Mississippi. Between the three, production is up 22 percent, while the overall exports from the facilities have increased by 100,000 units, Diaz told reporters.

Nissan Quest under investigation for inaccurate fuel gauges

After receiving 12 complaints in the last 14 months, the National Highway Traffic Safety Administration has begun a preliminary investigation into a fuel gauge issue with the 2007 Nissan Quest. Drivers have reported that the fuel level gauge will show there's gas in the tank when there actually isn't - in two cases, the digital distance-to-empty gauge indicated more than 70 miles of remaining range - and it will stall out.
This is the second time the 2007-model-year Quest has been involved in the same fuel gauge issue. In 2010 Nissan recalled seven models, including the Quest, from the 2005-2008 model years because of faulty fuel readings. The 12 vehicles in this latest complaint could have slipped through the cracks then, but we'll find out more when NHTSA updates its progress with the investigation into the estimated 37,656 units.
