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 reveals radical BladeGlider concept for Tokyo debut

Radical reinvention of the automobile doesn't happen very often. There's a reason they refer to it as "reinventing the wheel", after all. But that's what a team of racecar designers did with the original DeltaWing concept in 2010. Originally proposed as an IndyCar racer, the project was subsequently redesigned for Le Mans. That's when Nissan got on board, supported the project for a few races, then took the design in its own direction with the ZEOD RC. And now it's taking it to the road... via the auto show.
What we have here is the BladeGlider concept, a proposal for a delta-shaped electric sportscar which Nissan will present at the Tokyo Motor Show in a couple of weeks. Designed to focus on driving pleasure, the BladeGlider is about as radical as they come. Like the DeltaWing and ZEOD RC, it's got a narrow front track and wide rear to minimize drag and optimize stability, packing a 1+2 seating arrangement to put the driver front and center like in a McLaren F1, with upward-swinging doors and underbody aerodynamics to keep it glued to the road. In-wheel motors (of unspecified output) provide the power, a lightweight lithium-ion battery (not to mention the carbon-fiber bodywork) keeps it all fearther-like, and weight distribution is heavily biased towards the rear at 30:70.
A radical concept, to be sure, but here's the kicker: Nissan wants to build it. As you can see from the press release below, the BladeGlider "is both a proposal for the future direction of Nissan electric vehicle (EV) development and an exploratory prototype for an upcoming production vehicle". While it would undoubtedly take some time to develop, much less certify for road, seeing one of these - or even better, driving one - on our favorite stretches of tarmac strikes us as a prospect worth waiting for.

2014 Nissan Versa Note

The original Austin Mini was not designed as a fun-to-drive, sporty small car. Its go-kart-like handling and general chuckability were an unintended byproduct of essential aspects of its design. Its four wheels were pushed to the absolute corners of the car to maximize interior space, and its front-wheel-drive layout and transversely mounted engine were in contrast to the rear-wheel-drive, longitudinal layouts of the day.
The result was a highly economical car with space for four and some luggage that just happened to be an absolute hoot to drive. Nissan has followed a similar path in the design of its Versa Note, which strives to provide the maximum amount of space and efficiency in a minimal footprint. On this front, it's successful.
First, we must salute Nissan for departing from the styling of the malformed kidney bean it calls the Versa Sedan. The Versa Note is a fashionably conservative design that neither offends nor excites. The front fascia is arguably its most conservative point, with high-mounted headlights and a sharper, cleaner version of Nissan's familial grille. The tail, with its funky I-don't-know-what-shape-I-am taillights contributes most of the car's flair. The large, spacious greenhouse, particularly up front, keeps passengers from feeling hemmed-in while letting in plenty of light.
