Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Recharge Wrap-up: Mercedes-Benz B-Class Electric Drive goes on sale in Europe, Spain gets Nissan Leaf taxis

The new Mercedes-Benz B-Class Electric Drive goes on sale in Europe on November 3, with deliveries starting before the end of the year. Developed with the help of Tesla, the new electric B-Class offers more than 132 kilowatts (177 horsepower) and 250 pound-feet of torque. It features Economy Plus, Economy and Sport driving modes. An optional radar support system uses the collision prevention assist sensors to help make smarter decisions about when and how to use the regenerative braking. The B-Class Electric Drive also offers an optional Range Plus button, which can unlock more battery capacity when charging for the occasional longer drive. Learn more in the press release below. Racing returns to the streets of Miami for the first time in more than a decade for the Formula E Miami ePrix on March 14, 2015. Formula E has revealed the track layout, which takes the race around the Miami Heat's home court, American Airlines Arena, along the Biscayne Bay. "This event will help to make Miami more of a sports city," says Mayor Thomas Regalado. "In addition, we will show the younger generations that you may have motor racing without noise or pollution." Read more about the event at the Formula E website and see the track layout in detail here. Hyundai has delivered the first ix35 Fuel Cell vehicles to customers in the UK, including clean energy company ITM Power. ITM is responsible for three of the hydrogen refueling stations being built around the EU as part of the Hydrogen For Innovative Vehicles project - the same project that helped bring the Hyundai ix35 (also known as the Tucson) Fuel Cell to Europe. ITM's 700-bar hydrogen stations will be built in London by Spring 2015, each with its own electrolyzer system on site. In the meantime, ITM will use the ix35 for commutes between London and Sheffield, refueling at a site that uses wind-generated electricity from an on-site turbine to power the electrolyzer to make the hydrogen.

Aluminum supplier Novelis says demand will likely increase 30 percent annually for the next 10 years in China, Japan and Korea, and possibly more depending on how China's plan to increase EV use and decrease air pollution shakes out.

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.
