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.

Infiniti rolls out new badge, brand experience — even a brand scent

Infiniti kicked off a brand refresh Thursday, showing off a new logo (and corresponding changes to its physical emblems), dealership aesthetic and what brand representatives described as elements of its "multisensory experience." Do you know what Infiniti is supposed to smell like? Well, you're about to learn.  The alterations to the logo are subtle from dead on, but as you can see from our featured image above, its physical form is far more intricate and three-dimensional. This is the fourth generation of Infiniti's signature since the brand was launched in 1989. Yep — Nissan's upscale division is 35 years old this year. Can you believe that? The most significant visual difference is the alterations to the "road" in the center of the logo. Infiniti says this was done to emphasize the notion that the road is endless — infinite, if you will. The clipped point represents the horizon. The physical badges will be illuminated, "boldly" announcing the car's arrival.  "Our aim was to subtly evolve the INFINITI logo in support of the bright new chapter that lays ahead," said Alfonso Albaisa, Infiniti SVP of global design. "Adding greater emphasis to the point where the infinite road intersects with the horizon, we are showcasing our steadfast commitment to always look forward to the future and to new horizons." The new badge will also be accompanied by a new signature scent and signature sound. The former is a blend of Japanese cypress, cedar and yuzu. The sound "creates a sense of anticipation by marrying powerful musical elements with more serene sounds to deliver a harmonious balance" and will be employed in marketing materials, advertising, dealership experiences and other consumer-facing assets.  A new architectural and interior design direction accompanies the update. The aesthetics are based on the Japanese concept of Ma — "a philosophy that considers the space between things," Infiniti said. The result looks modern, sophisticated and convincingly upscale, reminding us of a cross between a Volvo and Mercedes-Benz showroom. Not a terrible place to be.  Infiniti's new look rolls out today across its digital spaces.

Nissan Canada to end Versa sales with Micra launch

There's plenty of space in Canada. In fact, with the second largest land mass of any country in the world, Canada has a population density of just nine people per square mile. But apparently there isn't enough room for more than one cheap Nissan in the True North, Strong and Free.
As you may recall, Nissan Canada recently announced it would begin offering the Micra hatchback with a starting price of less than ten thousand Canadian dollars - significantly less than the nearly $12k it charges for the Versa sedan. As a result, Nissan will reportedly cease offering the Versa sedan in new home of the olympic gold medal for hockey.
Apparently the Versa was a slow seller in Canada, a country in which European tastes tend to prevail - particularly in the Eastern provinces - more than they do in the United States to the south. Nissan evidently hopes that the Micra (a model created principally for the European market) will do better than the American-centric Versa ever did there. According to sales numbers cited by Automotive News, Nissan sold barely more than 12,000 Versa sedans and hatchbacks in Canada last year, but over 117,000 in the United States.
