Batteries

It is my fervent belief that nanotechnology’s ability to push the lowly battery to new heights will be one of the field’s biggest achievements in the not-too-distant future. Sure expanding the water supply and better harvesting the sun’s energy are no doubt big achievements. But...

Finally, after almost four years, we've driven the 2011 Chevrolet Volt in a variety of conditions, talked over our impressions, and reached a conclusion: Yes, the 2011 Volt electric car is a real car. It may be propelled by electricity. It may plug into a wall socket or a special garage recharger...

Electric cars may run clean. But how green is the battery? Hi, this is Steven Cherry for IEEE Spectrum's "This Week in Technology." With governments around the world investing heavily in electric and hybrid cars, the demand for the batteries that power these vehicles is on the rise. The United...

Like us, you may eagerly have been awaiting the arrival of the 2011 Hyundai Sonata Hybrid. You may even be planning to buy one. One of the reasons may be the tax credit for purchase of a hybrid vehicle that you can claim when you file your taxes. The 2011 Sonata Hybrid will qualify you for a credit...

As electric cars make their way to market, one funky little vehicle has captured plenty of attention for its unusual looks. That would be the Aptera 2e. The car is more than just an exercise in styling: Aptera plans to bring the car to market in late 2011. To that end, the company has been bringing...

Coda Automotive, the California startup that will begin delivering its 2011 Coda Sedan electric car at the end of the year, has ambitious plans. CEO Kevin Czinger expects to sell up to 14,000 all-electric compact sedans in the company's first full year of operations. The car is assembled in the...

Sometimes we avoid covering certain cars, for good reasons or not. One of those cars is the 2011 Wheego LiFe, a derivative of the 2009 Wheego Whip. Never heard of it? Not surprising. Wheego Electric Cars is a startup electric-car company, in this case selling an electric conversion of a...

Electric cars may be coming out in force come December, but the spotlight is now on how their batteries will be resold and recycled several years down the road. There’s been a recent spate of announcements from Nissan, General Motors and Tesla on this topic. All three companies are looking...

Pretty much everyone loves renewable energy. The problem is that wind usually blows at night--often sporadically, at that--and solar power is unpredictable. Suppose the secret to harnessing their potential was ... used electric-car batteries? GM said today that it would work with ABB Group to...

In pursuit of its goal to become a world leader in electric-vehicle technology, the Chinese government is considering new rules that will effectively require ceding critical intellectual property on electric car technology to Chinese owned companies. The proposed regulations from the Chinese...

As electric cars start to increase in power and range, so do the stresses and requirements placed on their oh so vital batteries. Most automakers have chosen to stick with lithium-ion batteries to power their new generation of electric vehicles and one of the crucial factors determining the...

In a week where many mainstream media outlets are claiming electric cars are prohibitively more expensive to own than gasoline counterparts, a team of Swiss researchers have released conclusive data showing that the environmental impact of the electric car is much less than most gas cars. As any EV...

The electric motor is a great invention, but it's entirely limited by the power that the battery can feed to it, and that power is limited by the amount of energy the battery can store. Battery technology is in constant development behind the scenes, though, and the latest to emerge in research at...

General Motors has been through the wringer over the last 18 months, nowhere more so than in North America, where it declared bankruptcy and was quickly restructured with $60 billion of Federal funds. But its overseas operations haven't had an easy time of it either, including its on-again...

The dog days of summer may still be with us, but automakers across the globe are gearing up for the big Paris Motor Show, which kicks off just six weeks hence.

Last week, advanced battery company A123Systems announced that it was spinning off a new venture called 24M Technologies, which would focus on more unorthodox energy storage innovations, including grid-scale flow batteries. One of the reasons it decided to release the new entity into the wild was...

Despite initial purchase prices higher than those for gasoline cars of equivalent performance (before incentives, anyway), electric cars undisputably cost less to run. Not only does the grid electricity to drive a mile cost just half to one-fifth the cost of the gasoline to go the same distance...

Almost a year ago, Infiniti confirmed a hybrid version of its new M sedan, to be launched at the end of 2010. Now, the company has unveiled that car, in the tony surroundings of the Pebble Beach Concours d'Elegance, the premier U.S. showcase for classic cars. Infiniti has adopted the Lexus...

Advanced battery maker A123 announced more than its quarterly earnings yesterday. In addition to posting a lackluster $22.6 million in revenue, the company spun off a new energy storage startup called 24M Technologies to work on more unorthodox lithium-ion architectures. The company also tempered...

Patience is a virtue when it comes to ordering a 2011 Nissan Leaf--especially if you're not in one of the five markets Nissan's chosen to launch the car late this year. On April 20 of this year, I was one of those electric-car geeks scanning my email every 15 minutes, waiting for the official...
