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 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.

Nissan starts building e-NV200 in Spain [w/video]

It doesn't look all that much like a Nissan Leaf, but the new e-NV200 that started production in Barcelona, Spain today shares its powertrain and lithium-ion battery with the world's most popular electric vehicle. The production version of the electric cargo van was unveiled late last year and today's manufacturing start is right on time with the company's previously announced timeline. The first exports will take place in June. The e-NV200 is Nissan's second all-electric vehicle, and the company says that powertrain line-up is "expanding." The vehicle itself will be available in a number of configurations in Europe: a light commercial van, a passenger vehicle and and electric taxi. Nissan has said in the past it is working on installing a fast-charging network of CHAdeMO stations in Barcelona, where the e-NV200 will be used as a cab. The e-NV200 will also be used as an electric taxi in Amsterdam. The zero-tailpipe-emission van is also being tested in Washington, DC with FedEx, but there is no confirmation that it will ever be commercially available in the US. There are a few more details, and a video, on the e-NV200 production start below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

The ceremony was attended by Spanish Ministry of Industry, Jose Manuel Soria, Catalan President, Artur Mas; and the Mayor of Barcelona, Xavier Trias, who were welcomed by Nissan's Chief Planning Officer, Andy Palmer. The Nissan plant in Barcelona will be the global production site for this ground breaking zero-emission vehicle, which will be available as a light commercial van, passenger vehicle and electric taxi in the European market.
