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 Cube dead for 2015

Another class cut-up has graduated from our motor pool. The Nissan Cube's indefatigable weirdness was likely both its chief selling point and its Achilles Heel, but Autoblog sources say that after a six-year run in the US, the niche player has been scrubbed from the Japanese automaker's lineup.
The move is hardly unexpected - there was confirmation from Nissan Canada that it was pulling the plug on the asymmetric little front-driver in its market back in May, and sales have not exactly been sparkling here in the States, either. In June, Nissan shifted just 336 Cubes, down 23.8 percent year over year. So far this year, Nissan has sold 2,294 units, a sales pace off 30.9 percent versus 2013. At its peak in 2010, the Cube remained firmly a niche vehicle, selling 22,968 units.
Nissan North America's Dan Passe, senior manager of product communications, maintains that "We are continuing to sell the 2014 Cube and we haven't made an announcement about future model plans," but Autoblog sources indicate that an official announcement will be coming in the next couple of months, and the Cube has been conspicuously left off of an exhaustive 2015 lineup "Charting the Changes" announcement released on Tuesday.

Nissan testing experimental dealer with no desks or offices

Nissan thinks it has found a better way to sell cars, and it involves stripping showrooms of everything but the cars and sales team. The brand calls the experiment the Nissan New Retail Concept, and it might get tested in the US in a few years.
The concept is relatively simple. Showrooms ditch offices, reception counters, cubicles and desks. Instead salespeople walk around inside and outside the dealer with mobile devices to assist customers and even complete sales. Associates are trained to take immediate responsibility for each visitor they encounter. For example, if owners comes inside with a problem with their vehicle, the employee escorts them to the service department and introduces them.
A dealer in London has been testing the new layout for the last nine months, and so far it reports better customer satisfaction, loyalty and most importantly higher sales. Nissan next plans to launch test stores in Moscow and Stuttgart. Then it will broaden out to more of Western Europe and finally will be tested in the Japan, the US and the Middle East, according to Automotive News.
