Nissan e-NV200 EV charges into Tokyo

Nissan has already shown its e-NV200 in Detroit and Frankfurt in conceptual form, now its home market is getting an up-close look at the production all-electric compact van at the Tokyo Motor Show. While it doesn't sound like the e-NV200 will be making its way to the US anytime soon, it will go on sale on sale in Europe in the middle of next year and in Japan by early 2015.
The electric NV200 will be built in Barcelona, Spain, and while that EV-minded city has committed to using the van for public transportation, Nissan's hometown of Yokohama, Japan will also put the zero-emission vehicle to work in its public services fleet. Nissan has yet to reveal the production specs for the e-NV200 - including range - we do know that it will share much of its drivetrain with smaller Nissan Leaf. Check out the press release posted below for more information about the e-NV200 and Nissan's EV efforts in Yokohama.

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.

Renault planning a Tata Nano rival. Again.

Four years ago, Renault confirmed that it would partner with India's Bajaj Auto to develop a rival to the Tata Nano. At the time, as everyone waited for the Tata Nano to arrive, you could have used a Richter scale to measure the tremors the executive suites of any automaker with an interest in the low end of emerging markets. Then the Nano, still the cheapest car in the world, didn't sell so well - at the end of last year its sales were just six percent of its most conservative projections - and everyone seemed content to let Tata spend the money to figure out if there really was a market for the cheapest car in the world.
Renault believes there is, kind of. Automotive News Europe reports that it will partner with Nissan to build two low-priced cars for emerging markets, one for €3,000 ($3,888 U.S.) and another for €5,000 ($6,400 U.S.). The price of the least expensive offering is nearly $1,400 more than a Nano, which costs $2,500, and that can't be considered a small sum in comparison. But one of the hindsight knocks on the Nano has been that even in emerging markets buyers don't want a car whose biggest lure is that it is cheap; they'd rather give their aspirations a bit more of a workout.
Renault's offerings are scheduled to hit the non-Western market in late 2014, which is coincidentally the same year that will see the return of the budget-minded and emerging-market-specific Datsun nameplate. They'll be built in Renault facilities in Chennai, India, with no mention made of Bajaj this time around.
