Nissan Leaf becomes least expensive 5-seat EV with massive price drop

In a roundtable interview today at the North American International Auto Show, Nissan CEO Carlos Ghosn announced a $6,400 price drop for the base-model 2013 Nissan Leaf. Last year's base model was $35,200, while the new base-level 2013 Leaf S starts at $28,800. Ghosn says the new prices make the Leaf the least expensive five-seater electric for sale in the US.
Some of the lower cost is due to a difference in content from last year's low-end model to this year's. But a sizable portion can be chalked up to the Leaf's production moving from Japan to Tennessee. The 2013 Leaf is not only assembled in the US now, but its lithium-ion batteries and the car's electric motors are manufactured in the same southern state.
The Leaf SV will be priced from $31,820 for 2013 compared to $35,200 last year. The high-end Leaf SL now starts at $34,840, down from the 2012 model's $37,250. These models also have differences in content. One big one is a new 6.6-kWh charger that reduces charging times pretty dramatically.

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.

Recharge Wrap-up: Eigg's renewable energy grid, Wulin City Car EV looks like i3

Scotland's Isle of Eigg's electrical grid relies solely on wind, hydro and solar power. It's the first grid of its kind after switching to renewable energy from noisy, unreliable diesel generators. Scotland's renewable resources are fodder for supporters of independence form the UK, and Eigg is a perfect example of that potential. Besides being a responsible community, it also seems like a lovely place to visit. Read more at Reuters. London Mayor Boris Johnson is calling for incentives for diesel vehicle scrapping. The goal is to improve London's air quality, encourage the purchase of clean vehicles and offset the inconvenience of charging diesel cars to enter the city's proposed Ultra Low Emissions Zone.

As part of the Trans-European Transport Network (T-ENT) program, the group aims to create extended EV-friendly roadways with the UK Rapid Charge Network, connecting major cities on the islands. Plans for the network include 70 rapid chargers along 684 miles of road. The four manufacturers also want to extend the project to mainland Europe to encourage the adoption of EVs.

The City Car EV concept is slated to make its debut in November at the Guangzhou Auto Show, while a production version could make its way onto Chinese roads next year. We might have to wait until the debut to know what powers the City Car, as those details haven't been released yet. General Motors is a 43-percent stakeholder in Wuling.

Now customers will be able to use either app to pay in any of the city's 20,000 green and yellow taxis. There's no need for separate apps for separate cabs, and no need for drivers to install any new equipment. The groups behind the apps hope to expand this functionality to other cities across the country. Read more in the press release below.
