Video: Coda Automotive bringing Miles Electric's sedan to California in 2010

by Darren Murph posted Jun 4th 2009 at 11:22AM

Remember that Miles Electric sedan we heard about last month? Yeah, well it's coming to California's shores next year. An all new car company, doing business under the name of Coda Automotive, has just been formed in order to bring said vehicle into production. The all-electric, four-door Coda won't break down any walls in the design department, but the $45,000 (mid-$30,000s after a $7,500 Federal tax credit and additional state incentives) whip sure sounds promising as an eco-friendly daily driver. Reportedly, it'll cruise for around 90 to 120 miles without needing a recharge, and the batteries within can be charged enough for a 40-mile commute in two hours. It'll also ship with a navigation system, Bluetooth, iPod support and power everything as standard, but sadly, there's no telling when it'll be sold outside of the The Golden State. Video promo is after the break.

More scientific black magic promises to double Li-ion battery capacity

by Darren Murph posted May 30th 2009 at 11:52PM

Go on and file this one away in the folder of "awesome things that could, but won't ever happen." As the brilliant minds around the world figure out how to solve vicious diseases, move motorcars with peanut oil and send engineers to fix a telescope in outer space, we still can't buy a pack of AA cells that last longer than a month or two in our favorite toy. Some call it a limit of physics, some deem it a conspiracy. Whatever the case, we've no doubt whatsoever that a new silicon-containing carbon material -- designed by Dow Corning Toray to double the capacity of existing Li-ion batteries -- won't ever have a real impact in our lives. Of course, it's not like any consumer would actually benefit from having a netbook battery good for 16 hours, nor would wedding photographers enjoy being able to shoot 1,000 indoor shots without cracking the battery door open on their SB-600. No -- that's just absurd. C'mon Dow, prove us wrong here.

Air-fuelled STAIR battery could last ten times longer than traditional cells

by Darren Murph posted May 23rd 2009 at 11:44AM

It's funny, really. We've figured out how to put men an women on the moon and repair an orbiting telescope, but we can't concoct an AA battery that lasts more than four days inside a Teddy Ruxpin. Thanks to a revolutionary new design from the labs at the University of St Andrews, all that could be well on the way to changin'. Researchers at said institution have teamed up with partners at Strathclyde and Newcastle in order to design an air-fuelled STAIR (St Andrews Air) cell that could theoretically last up to ten times longer than current batteries. Put as simply as possible, this design utilizes oxygen in the air as a re-agent instead of heavy, costly chemicals; the result is a lighter, cheaper battery with loads more capacity. Needless to say, gurus within the project are already dreaming of a prototype to fit in small gizmos such as cellphones or MP3 players, though we wouldn't expect one anytime soon -- after all, there's still two years of research left to complete.

Toshiba dramatically increases energy density of Li-ion battery

by Darren Murph posted Apr 15th 2009 at 10:12AM

The last time we heard of lithium titanate battery technology was when learning about the £120,000 Lightning GT, and while we've no way to confirm, we're definitely hoping that the latest development from Toshiba ensures that we're talking about it far more frequently than once per year. According to a report over at Nikkei's Tech-On, said outfit has crafted a cell of a Li-ion secondary battery (aimed at electric vehicles, mainly) that sports an energy density as high as 100Wh/kg. Needless to say, the invention relies on lithium titanate for its negative electrode, and considering that Tosh is currently producing a 4.2Ah cell with an energy density of around 67Wh/kg for electric bicycles, it's easy to see what kind of improvement we're staring at. Now, if only this stuff could be applied to AA cells, our power-gulping camera flash would be forever grateful...

AMD proposes new laptop battery life metrics, Intel is like "whatevs"

by Darren Murph posted Mar 14th 2009 at 6:23PM

AMD has struggled of late to produce anything akin to a "good idea," but we've got to give a serious high five to senior VP and CMO Nigel Dessau on this one. While pumping gas one day and thinking about the low / high MPG ratings on vehicles, he began to wonder why laptops are being left out of that scheme. Handsets have talk time / standby time, PMPs have separate longevity ratings for audio and video -- so why on Earth are we generally given just a single figure for laptops? Testing has shown that almost always the quoted figures from laptop makers aren't even close to what users get in the real world, so Dessau is suggesting we implement a "guide rail" system that explains a maximum and minimum life expectancy. As for Intel's take? "There are many ways to measure battery life. We believe the best way to determine how to measure battery life is by making proposals and debating it in industry consortiums and not via a blog post." Oh Intel, could you possibly be any more corporate?

MIT's quick charging batteries could revolutionize the world, maybe

by Darren Murph posted Mar 12th 2009 at 9:36AM

Okay, so maybe the headline is a tad on the sensational side, but seriously, this has sensational written all over it. A team of brilliant MIT engineers have conjured up a beltway of sorts that allows for "rapid transit of electrical energy through a well-known battery material," something that could usher in smaller and lighter cells that could recharge in moments versus hours. There's even talk that this technology could be adapted for use in automobiles, and honestly, it doesn't take an electrical engineer to understand how rapid charge / discharge batteries could "induce lifestyle changes." Hey, laptop battery makers -- could you guys look into getting these ready to go in machines by CES 2010? That'd be swell, thanks.

Recalled: 35,000 volatile Sony batteries in Dell / HP / Toshiba laptops

by Darren Murph posted Oct 30th 2008 at 5:25PM

Ruh roh. We're really, really hoping this isn't just the first of another long string of laptop battery recalls, but the US Consumer Product Safety Commission, in cooperation with a slew of other outfits, has just announced a voluntary recall of around 35,000 Sony laptop batteries. As you'd expect, the Li-ions in question "can overheat, posing a fire and burn hazard to consumers," and there have already been 19 reports of overheating including 17 reports of flames / fire and two reports of consumers getting mildly burnt. For the full list (and it's pretty long) of affected laptop models from HP / HP Compaq, Toshiba and Dell, be sure to give the read link some serious attention. Oh, and stop using that battery pronto if yours is one of the afflicted.

6-cell battery emerges for Acer Aspire One: $119.99 for a few more hours

by Darren Murph posted Aug 4th 2008 at 7:34AM

We fully understand that time is money, but damn. With quite a few folks up in arms over the $50 to $100 price hike on the 6-cell MSI Wind over the standard 3-cell version, we can only imagine the outcries that will come after seeing this. CDW has a product page up that describes an Acer Li-ion 6-cell 5,200mAh battery that's designed to fit snugly within the $379.99 Acer Aspire One netbook. Let's see here -- a $119.99 battery for a $379.99 computer. Is that the absurdity alarm sounding, or are our ears still ringing from all the weekend revelry?

Microwave process could cut cost of lithium-ion batteries

by Donald Melanson posted Jul 30th 2008 at 6:47PM

While there's plenty of folks out there focused on making lithium-ion batteries safer and longer-lasting, there's also thankfully some dedicated to making 'em cheaper, which is especially welcome when we're talking about the expensive batteries powering cars. Among those in the latter camp is University of Texas at Austin professor Arumugam Manthiram, who has devised a method of using microwaves to heat a concoction of commercially available chemicals, which ultimately results in the Rorschach test of rod-shaped particles of lithium iron phosphate pictured above. While the use of lithium iron phosphate instead of the more commonly used lithium cobalt oxide apparently cuts back on the total amount of energy the batteries can store, it is apparently particularly well-suited to delivering large bursts of power, which should make the batteries ideal for use in hybrid vehicles. What's more, while the actual cost of the materials may not be much cheaper than other solutions, the sheer speed at which Manthiram's process works could allow for higher production rates from the same amount of equipment, which should result in cheaper batteries by the time they roll off the assembly line.

Penguin United offers its own quad Wiimote charging station

by Darren Murph posted Jul 30th 2008 at 4:36PM

Two 4x Wiimote charging stations in a week? Um, okay. If, for whatever reason, the Nintendo-licensed charger we saw just days ago wasn't right for you (read: too expensive to import), we've got yet another option for you to consider. Penguin United -- which gets brownie points on name alone -- has just unveiled the Quad Charge Station for Wii, which utilizes Li-ion batteries that promise 13 full hours of playtime from each Wiimote. Additionally, it can juice up your controllers in just 4 hours, and there's even LEDs to inform you of how close to full each one is. The real kicker? The colored Wiimote straps that PU tosses in -- huzzah! Include one in your next party for $44.99.

GM cranks up battery tests for plug-in Volt

by Darren Murph posted Apr 4th 2008 at 5:23PM

General Motors doesn't have long before everyone and their cousin expects to see at least a few Volts on the road -- and it knows it. In an attempt to make sure the deadline is met, the firm has battery testing going on 'round the clock in Michigan and Germany that will theoretically simulate a decade of use in just two years. Additionally, it's placing batteries in test Malibus in order to get a feel for real-world results. Still, GM has yet to definitively decide on the final engine or which battery supplier it'll end up working with, but as the eleventh hour grows ever closer, we can only hope that the pieces start to come together.

Mercedes S400 BlueHybrid aims to be first to use Li-ion battery

by Darren Murph posted Mar 1st 2008 at 1:04PM

There's a decent chance your average hybrid owner wouldn't know the difference between a lithium-ion and nickel-metal hydride battery if their life depended on it, but we know you -- dear reader -- are not one of those "average" joes / janes. That being the case, you may be interested to know that the 2009-bound S400 BlueHybrid is in prime position to be the world's first production Li-ion hybrid, which will offer up "compact dimensions and far superior performance" compared to existing rivals. M-B goes on to trumpet the technology's "high ampere-hour efficiency, long service life, and great reliability, even at very low temperatures." No word on just how astronomically high this thing will be priced at, but you can expect just shy of 30 miles-per-gallon in mixed driving conditions, for what it's worth.

Tektronix oscilloscopes could catch fire due to volatile Li-ion

by Darren Murph posted Oct 16th 2007 at 3:01AM

We've seen some strange devices catch fire due to faulty batteries, but this one just may take top honors. Apparently, a pair of Tektronix oscilloscopes (model numbers TDS3000 and TDS3000B) have the potential of catching fire; according to the company, it has received two reports of the units "burning at customer sites." Upon closer inspection, it was noticed that the machines both relied on a TDS3BATB Li-ion battery, which is now carrying the blame for the unexpected blazes. If you or a loved one just so happen to own or use one of these rigs in your everyday life, Tektronix is suggesting that you power it down and stop using the battery until further notice.

Zero Motorcycles cranks out whisper quiet electric bike

by Darren Murph posted Aug 3rd 2007 at 6:54PM

Can't scrape together enough coin to pick up an electric whip? Fret not, as your options in the not-gasoline-powered motorcycle realm are quickly expanding. Enter Zero Motorcycles, which already offers a Zero X dirt bike for a mere $6,900, and hopes to unleash a street-legal commuter motorcycle soon that will be "slightly larger and more powerful than the Zero X" and will sport the obligatory lights and turn signals necessary for street riding. Currently, the off-road flavor will cruise 40 miles on a single charge, can be recharged in just two hours, can be shipped in a cardboard box, and reportedly accelerates beyond 30mph in "just a few seconds." And if you're just now daydreaming about how splendid it would be to take one of these out for a spin, be sure and visit the read link below to live vicariously through a few lucky CNET employees.
