The U.S. Department of Energy (DOE) recently announced $209 million in funding for 26 new laboratory projects focusing on electric vehicles, advanced batteries, and connected vehicles. DOE’s Argonne National Laboratory introduced Li-Bridge, a new public-private partnership to bridge gaps in the domestic lithium battery supply chain. Advanced lithium-based batteries play an integral role in 21st century technologies such as electric vehicles, stationary grid storage, and defense applications that are critical to securing a clean energy future. The projects support goals to make the United States a global leader in electric vehicle and battery innovation; advance the development of these technologies to save families money; lower carbon pollution; and create high-quality jobs.

The search for the next level, new, and improved electric vehicle battery is an ongoing one. And it’s one Honda may have found. According to The Drive, the Japanese automaker claims to have developed a new battery chemistry called fluoride-ion that could outperform current lithium-ion batteries.
Honda says fluoride-ion batteries offer 10 times greater energy density, meaning more storage and range for electric vehicles, thanks to the low atomic weight of fluorine that makes fluoride-ion batteries’ increased performance possible. (more…)
High-end, high-class, and high-cost are all words synonymous with the word Bentley. The luxury car CEO Adrian Hallmark says he plans to keep it that way, and for that reason, he’s giving the inclusion of electric vehicles to the Bentley family the red light—for now.
When will cars powered by gas-guzzling internal combustion engines become obsolete? Not as soon as it seems, even with the latest automotive news out of Europe.
First, Volvo announced it would begin to phase out the production of cars that run solely on gasoline or diesel by 2019 by only releasing new models that are electric or plug-in hybrids. Then, France and the U.K. declared they would ban sales of gas and diesel-powered cars by 2040. Underscoring this trend is data from Norway, as electric models amounted to 42 percent of Norwegian new car sales in June.
European demand for oil to propel its passenger vehicles has been falling for years. Many experts expect a sharper decline in the years ahead as the shift toward electric vehicles spreads across the world. And that raises questions about whether surging electric vehicle sales will ultimately cause the global oil market, which has grown on average by 1 to 2 percent a year for decades and now totals 96 million barrels per day, to decline after hitting a ceiling.
Energy experts call this concept “peak oil demand.” We are debating when and if this will occur.
Around the world, the transportation sector is evolving. Globally, electric vehicle (EV) sales have more than doubled, showing a 72 percent increase in 2015, followed by 41 percent global increase in EV sales in 2016. Now, France is committing to a greener transportation sector by vowing to end the sale of gasoline and diesel vehicles by 2040, further pledging to become a carbon neutral country by 2050.
Currently, 95.2 percent of new car fleets in France are represented by gasoline and diesel vehicles. According to France’s Ecology Minister Nicolas Hulot, initiatives by automakers such as Volvo to go all electric in the coming years will help France start to phase out gasoline and diesel vehicles.
In order to become carbon neutral by 2050, France will also need to devote energy to ending the use of fossil fuels across the board, which includes ending hydrocarbon licenses in the country and stopping coal production by 2022.
While France’s goals are admirable, organizations such as Greenpeace believe that the measure falls short in terms of concrete measures.
“We are left wanting, on how these objectives will be achieved,” Greenpeace campaigner Cyrille Cormier said in a statement. “The goal to end the sale of gasoline and diesel vehicles by 2040 sends out a strong signal, but we would really like to know what are the first steps achieve this, and how to make this ambition something other than a disappointment.”
Using energy stored in the batteries of electric vehicles to power large buildings not only provides electricity for the building, but also increases the lifespan of the vehicle batteries, new research shows.
Researchers have demonstrated that vehicle-to-grid (V2G) technology can take enough energy from idle electric vehicle (EV) batteries to be pumped into the grid and power buildings—without damaging the batteries.
This new research into the potentials of V2G shows that it could actually improve vehicle battery life by around ten percent over a year.
For two years, Kotub Uddin, a senior research fellow at the University of Warwick’s Warwick Manufacturing Group, and his team analyzed some of the world’s most advanced lithium ion batteries used in commercially available EVs—and created one of the most accurate battery degradation models existing in the public domain—to predict battery capacity and power fade over time, under various aging acceleration factors—including temperature, state of charge, current, and depth of discharge.
Scientists have found a way to wirelessly transmit electricity to a nearby moving object.
The method may have applications in transportation, medical devices, and more. If electric cars could recharge while driving down a highway, for example, it would virtually eliminate concerns about their range and lower their cost, perhaps making electricity the standard fuel for vehicles.
“In addition to advancing the wireless charging of vehicles and personal devices like cellphones, our new technology may untether robotics in manufacturing, which also are on the move,” says Shanhui Fan, a professor of electrical engineering at Stanford University and senior author of the study.
“We still need to significantly increase the amount of electricity being transferred to charge electric cars, but we may not need to push the distance too much more,” he says.
Imagine if you could gas up your GM car only at GM gas stations. Or if you had to find a gas station servicing cars made from 2005 to 2012 to fill up your 2011 vehicle. It would be inconvenient and frustrating, right? This is the problem electric vehicle owners face every day when trying to recharge their cars. The industry’s failure, so far, to create a universal charging system demonstrates why setting standards is so important – and so difficult.
When done right, standards can both be invisible and make our lives immeasurably easier and simpler. Any brand of toaster can plug into any electric outlet. Pulling up to a gas station, you can be confident that the pump’s filler gun will fit into your car’s fuel tank opening. When there are competing standards, users become afraid of choosing an obsolete or “losing” technology.
Most standards, like electrical plugs, are so simple we don’t even really notice them. And yet the stakes are high: Poor standards won’t be widely adopted, defeating the purpose of standardization in the first place. Good standards, by contrast, will ensure compatibility among competing firms and evolve as technology advances.
My own research into the history of fax machines illustrates this well, and provides a useful analogy for today’s development of electric cars. In the 1960s and 1970s, two poor standards for faxing resulted in a small market filled with machines that could not communicate with each other. In 1980, however, a new standard sparked two decades of rapid growth grounded in compatible machines built by competing manufacturers who battled for a share of an increasing market. Consumers benefited from better fax machines that seamlessly worked with each other, vastly expanding their utility.
There’s a major player in the autonomous, electric car industry that may just outpace transportation mogul Tesla. Faraday Future, an American start-up focused on developing intelligent electric vehicles, just unveiled its first self-driving supercar called the FF91.
Faraday Future states that the vehicle’s 130 kWh battery delivers a range of 378 miles on a single charge. Additionally, 10 cameras, 13 radar sensors, and 12 ultrasonic sensors help power the vehicle’s autonomous abilities.
But Nick Samson, Faraday Future’s senior vice president of engineering, says that the FF91 is “more than just a car,” rather an “intelligent entity.”
In addition to the batter and self-driving tech, the FF91 boasts an infotainment system that allows passengers to watch TV based on your preferences, which are known by the car due to an online profile.
