AddFast charging your EV might not be as bad as predicted

Stanford, MIT, Sandia Show Rapid Charge, Discharge Cycle Likely Balanced In Pack

Tesla Model S owners rejoice, for any reports of a lithium-ion battery's rapid demise from fast-charging might be highly exaggerated. A study put together by researchers from Stanford, Sandia National Laboratories and MIT and published in Nature Materials refutes previous reports that indicate that rapid charging and intense use of electric-vehicle batteries degrades them at a faster rate than a slower, steadier recharge-discharge process.

AddFiguring out exactly how much it costs to charge Tesla Model S

Home Tests Show Anywhere Between 82 and 90 Percent Efficiency

Is the Tesla Model S an electricity guzzler? One driver trying to answer that question says it does gobble down more juice than previously thought, but it's not time to make Hummer jokes just yet.

AddDrive an EV and you, too, can pay the equivalent of 75 cents a gallon

One in six households can party like it's 1979 by purchasing a plug-in vehicle. Add a thumpin' sound system to that vehicle and you can celebrate by pumping out an appropriate hit from that year, too. We think Chic's Good Times would be appropriate.

AddHow to get incredibly accurate information on your EV's charging power

One would think that paying about $300 to receive a bit of bad news about electric-vehicle charging would be counterproductive. But the fine folks at Teslarati believe that truth is beauty, and they're willing to pay a little extra for the straight dope.

AddCharging millions of EVs at once? It's a math problem

Preparing for the brave new world where the number of plug-in vehicles looking for a charge grows high enough to match to the current electricity supply, one study from China's Sichuan University is suggesting a novel concept. It's called the honor system, and it might one day be needed to prevent the plug-in vehicle version of a brown-out.

AddNorwegian winter proving too much for some Tesla charging cables

Polar vortex 1, Tesla Model S 0? Possibly. Norway is certainly a long way from the sunny California climes where the luxury electric vehicle is made and, while the cars are popular in that country, the country's cold weather is creating problems for car owners, the Norwegian website News in English reports.

AddHow microscopes are improving EV batteries at PNNA

The construction of one small battery is helping scientists make a big breakthrough when it comes to studying the effects of repeated recharging of a rechargeable battery.

AddTesla Supercharger deployment lagging

Elon Musk and his Tesla Motors may be receiving kudos from everyone ranging from equity investors to Time magazine to crash-test regulators to the wealthy car-buying public, but one auto writer in the Northeast is taking the electric-vehicle maker to task for not deploying its Supercharger vehicle-recharging network as quickly as advertised.

AddUniversity of Illinois recharges li-ion battery a thousand times faster

Imagine recharging a Nissan Leaf from a standard 110-volt outlet in, say, oh, about a minute. Far-fetched, sure, but at least one research facility thinks it has a lead on making lithium-ion batteries that can recharge 1,000 times faster than current ones.

AddPlug-in vehicles go further every day. No, seriously

Here's a twist we didn't see coming.

AddTesla declares October 19 "Supercharging day"

Highway etiquette states that slower moving vehicles stay to the right. Those slowpokes may want to stay off California highways altogether this Friday.

AddCoda offers a 'year' of free charging for all-electric Sedan buyers

Electric-vehicle maker Coda Automotive is offering buyers a free year (roughly) of recharging, which sounds good no matter how you slice it. Specifically, Coda is giving a $552 rebate for folks who buy Coda Sedans this month.

AddEnvision Solar "trees" to charge the Chevy Volt

According to Envision Solar president Desmond Wheatley, "every electric vehicle is the equivalent of one or two single-family residences in terms of impact on the electric grid." Looking to reduce that impact, General Motors has partnered with Envision Solar to provide solar charging stations for the Chevrolet Volt at GM dealers. The stations serve a dual purpose: to provide shade and a charge. The shade it provides actually assists the charging function. Wheatley says that electric vehicles, wh

AddSave what? Southern California Edison launches rate calculator for plug-in vehicles

Southern California Edison (SCE) has launched an intuitive plug-in rate calculator that allows current and potential electric vehicle (EV) owners to assess the costs of "fueling" battery-powered vehicles. SCE customers input information like location, daily power usage, vehicle type (i.e., plug-in hybrid or battery-electric vehicle), mileage and expected time of day use (on- or off-peak hours) and the Plug-in Car Rate Assistant spits out an estimated monthly charging fee. It's an easy way to get
