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 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. NISSAN'S SECOND 100% ELECTRIC VEHICLE, THE e-NV200, STARTS GLOBAL PRODUCTION IN BARCELONA 05/05/14 Nissan e-NV200 is the second model in Nissan's expanding range of electric vehicles Barcelona plant starts production of Nissan's first electric van as part of ˆ431 million investment New electric van provides a zero-emission solution for urban cargo delivery and taxi companies Barcelona is the only Nissan plant to produce the e-NV200, which will be exported globally e-NV200 shares drivetrain technology with the world's best-selling electric vehicle - the Nissan LEAF BARCELONA – Nissan has started the production of its second all-electric vehicle, the e-NV200, which will soon be available in Europe as both a passenger vehicle and light commercial van. 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.

Nissan rowed the Note ashore [w/video]

Normally we wouldn't suggest trying to float your car on water, but Nissan has made some modifications to turn its new Versa Note hatchback into a makeshift rowing shell.
Nissan replaced the car's rear seats with a sliding rear rowing seat, modified the doors to open wider at 90 degrees and fitted a pair of oars. Most importantly, they put the whole thing on a floating platform to keep it from sinking into Eton Dorney Lake, the site of the 2012 Olympic rowing competitions in England (where the car is simply known as the Nissan Note).
Then they invited medal-winning competitive rowers Helen Glover, Sophie Hosking and Polly Swann to come along and row the thing, making use of the around-view monitor system to see where they were going. All in all it may not be quite as cool as the boats which Fiat made out of the 500 or Mini made out of its convertible, but it's still enough to float our boat. Check it out in the video clip and press release below and the image gallery above.
