NRG eVgo ready for 'No Charge to Charge' in Atlanta

That loop of highways circumnavigating the city of Atlanta is about to get some fast chargers. And, for those driving newer Nissan Leaf electric vehicles, some free chargers as well, for the next couple of years. It's the new taste of southern hospitality. NRG Energy, which has been expanding its NRG Evgo fast-charging networks across the country, is now going into the Atlanta metro area. The stations, which can fully charge an electric vehicle in as few as 30 minutes, will be located "along major thoroughfares in retail locations." This makes sense, since Atlanta has emerged as a major plug-in vehicle market this year. Additionally, the "No Charge to Charge" program that NRG eVgo helps administer will apply in NRG eVgo's Atlanta network. That means that Georgians who either buy or lease Leaf EVs will be allowed to charge their cars at the eVgo stations for free for the first two years. Other eVgo programs are up and running in Texas, Phoenix, Nashville, Washington, D.C. and the Pacific Northwest. Last month, the NRG eVgo program took over a proposed fast-charging network in Chicago, where charging-station deployments had stalled. Take a look at the NRG eVgo press release for Atlanta below. NRG eVgo Announces Electric Vehicle Charging Network in Atlanta ATLANTA, December 09, 2014 – NRG eVgo, a subsidiary of NRG Energy, Inc. (NYSE:NRG), is expanding its comprehensive electric vehicle (EV) infrastructure designed to support EV drivers whenever and wherever they choose to charge - at single family or apartment residences, at work, on the road, or even at the airport to the Atlanta metro area. The new network will give Atlanta EV drivers unprecedented access to cutting-edge fast charging technology and bring much-needed EV infrastructure to the region. "We are pleased that NRG has chosen to expand its eVgo charging network in the City of Atlanta," said Mayor Kasim Reed. "Establishing a robust fast-charging network is essential to even broader adoption of electric vehicle use, both here in Atlanta and across the country." Recently, according to IHS Automotive, Atlanta emerged as the second major metropolitan market for EV sales, following San Francisco. Atlanta is geographically large, meaning most people commute to work, and have a need for a sustainable, reliable charging infrastructure.

Why China will soon lead the electric vehicle market

China could be the world's largest electric vehicle market by 2020, thanks to significant government subsidies and the major drawbacks of owning an internal combustion model there. The country's populace registered 75,000 EVs in 2014, and sales figures in 2015 looked even better. In a new video, Renault-Nissan examines the trend and why it happened. Chinese cities heavily encourage buyers to go green through vehicle incentives, but they also make it a hassle to be a polluter. In some places, there's a lottery to limit vehicle registrations and alternating driving bans for even or odd license plate numbers. However, these limits don't apply to EVs, and the country's automakers have benefited from the regulations by introducing small, inexpensive electric models, albeit with sometimes hilarious styling. China's emissions regulations will get even tighter in the coming years. In fact, a Honda exec recently predicted the company wouldn't be able to sell any models there without some form of electric assistance by 2025.

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.
