Recharge Wrap-up: Nissan and Endesa launch V2G project; BMW denies Apple will use i3

Nissan and Endesa will work together to deliver a mass-market vehicle-to-grid (V2G) system. The technology would allow users to charge their vehicle during off-peak hours, and sell energy back to the grid during periods of high demand. The two companies are looking to launch V2G technology in Europe, as well as exploring second-life projects using retired EV batteries for stationary energy storage. V2G allows users to lower the cost of ownership of their EV, and also helps stabilize the grid, particularly in countries that use a large amount of renewable energy. Endesa will demonstrate its V2G technology system in Madrid on March 12. Read more from Nissan. BMW denies reports that Apple will build a car based on the i3. German magazine Auto Motor und Sport said that such a deal was in the works, and that the Apple car could be sold by Apple and serviced by BMW. "We are in regular talks with companies from the IT and telecommunications sector, including Apple, concerning topics like connected vehicles," says BMW. "Developing or building a car is not a topic of these discussions." Anonymous sources say that Apple could have a car available for production in 2020. Read more at Automotive News Europe. BluepointLondon will take over the management of 60 EV charging stations from Transport for London. The 60 chargers are in the boroughs of Southwark and Sutton, and Bluepoint expects to take over management of charging infrastructure in other London boroughs as well. "A better maintained and more extensive charging infrastructure will mean more drivers are able to use electric vehicles and join the early-adopters who are already helping London reach lower emissions level," says BluepointLondon Director Christophe Arnaud. "We are very excited to be playing our part." BluepointLondon aims to manage 6,000 charging points in London by 2018. Read more in the press release below. Efficient Drivetrains, Inc. (EDI) offers plug-in hybrid conversions for GM light-duty trucks. The PHEV drivetrain offers all the performance of the original model, but reduces consumption and emissions by as much as 80 percent. It offers 30 to 40 miles of all-electric range plus enough energy to act as an idle-free power supply for tools and the like without depleting range. The EDI drivetrain can even be used to charge other EVs. Says EDI's Charlie Travis, "The light duty truck class is an important and high-volume vehicle category for fleet owners.

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's Cummins tie-up bears first fruit with Frontier Diesel Runner concept

The 2014 Chicago Auto Show is proving to be a surprisingly big show for alternative fuels. The Chevrolet Silverado HD pickups are getting a compressed natural gas option and the refreshed BMW X3 is receiving a diesel engine, as is the German automaker's 7 Series. You can add one more oil burner to the mix, at least in concept form: Nissan has released its Frontier Diesel Runner Powered by Cummins with a 2.8-liter, four-cylinder turbodiesel engine and an eight-speed automatic transmission from ZF.
While Nissan calls the Cummins-powered Frontier a concept, it's really just a Frontier DesertRunner 4x2 with a diesel engine replacing the standard 4.0-liter V6, and it's meant to gauge consumer interest for a diesel option in the next-generation Frontier. Nissan has clearly noticed that Chevrolet will be offering a diesel in its new Colorado and wants to see how buyers will react to a mid-size alt-fuel pickup from a Japanese brand.
Exterior modifications to the concept are minor. To show off the engine, there is a transparent hood insert and the pickup has been painted in a two-tone finish of high-gloss red and matte silver edged in carbon fiber trim. The interior gets the same combo of red, silver and carbon fiber to match the outside.
