Eton anticipates next natural disaster with self-powered FRX radios

Sarah Silbert — Wed, 16 May 2012 15:38:00 EST

Eton, the name behind solar-powered sound systems and emergency radios, is updating its disaster-preparedness portfolio with the new FRX series of self-powered radios. The FRX 1, FRX 2 and FRX 3 use hand-turbine energy to keep the internal lithium ion battery juiced, and all include a glow-in-the-dark indicator, LED flashlight and DC input. While the FRX 1 offers only the basic components, the FRX 2 and 3 have solar panels for recharging, along with a headphone jack and a USB port for powering other gadgets. The FRX 3 boasts a digital alarm and radio -- as opposed to the analog radio on the FRX 2 -- and a display for receiving NOAA weather alerts. Eton priced the radios at $25, $40 and $60, respectively, and it's currently selling the three options with American Red Cross co-branding at outlets such as Amazon, Best Buy and REI.

Fisker rep defends Karma hybrid sedan in garage fire aftermath

Sarah Silbert — Tue, 15 May 2012 17:15:00 EST

Last week, a newly purchased Fisker Karma went up in flames, damaging its owner's home and earning the company behind that hybrid sedan plenty of bad press. The auto maker hasn't submitted an official explanation for the fire, though the former chief engineer for the late General Motors EV1 electric car places the blame on the hybrid's tight engine bay packing. Fisker clearly isn't having any of that -- according to the company's director of powertrain:

Our technologies and engine design have been fully tested and certified at the highest level. It is irresponsible and ill-informed for technology pundits to suggest otherwise in order to secure media attention for unfounded claims.

No defensiveness there, then.

USPS goes postal on lithium ion batteries, refuses to ship smartphones overseas

Daniel Cooper — Fri, 11 May 2012 07:15:00 EST

The USPS has announced that it'll refuse to ship any gear containing lithium ion batteries overseas. The postal service believes combusting power packs have caused two fatal cargo plane crashes since 2006 -- hence the ban, which takes effect from May 16th. Anyone wishing to ship the latest tech to those living or serving overseas will have to use another shipping company -- although the ban might be relaxed in 2013, once safety testing has been carried out.

Fisker Karma reportedly sets house on fire, doesn't restore cosmic balance (updated)

Jon Fingas — Tue, 08 May 2012 23:48:00 EST

Fisker's Karma woes aren't relenting anytime soon, as one new owner just found out the hard way. A driver in Sugar Land, Texas parked his recently obtained hybrid sedan in his garage last week, only to have the car self-immolate minutes later and damage his new home. Despite the slight risk of lithium-ion batteries catching fire, the luxury car's power pack (unplugged at the time) appears to have been left in one piece -- suggesting that something more complicated is at fault. For their part, neither Fisker nor insurance investigators are ready to offer a definite explanation as to what set the car on fire, although an electrical panel in the garage is a possible lead. Hybrids and pure EVs typically aren't at significant risk of igniting, so we might not ask for a refund... but we would recommend keeping an eye (and a nose) on any potential fire hazards around your eco-friendly auto.

Update: Looks like Fisker's about to take some more heat. Here's a statement from the owner's attorney:

The fire department recently completed their investigation and determined the origin of the fire was, in fact, Gutierrez's newly purchased Fisker Karma hybrid electric vehicle that he just took possession of two weeks earlier

GM to add 'enhancements' to Chevy Volt's battery coolant system, will call back 8,000 cars

Amar Toor — Thu, 05 Jan 2012 12:25:00 EST

In the wake of an NHSTA "formal safety investigation," GM today announced plans to add enhancements to the Chevy Volt's battery coolant system, in the hopes of preventing any post-crash electrical fires. As a result, some 8,000 Volt drivers will have to bring their cars back to their dealerships, as part of a move that's one notch below a formal recall. GM made the decision following federal investigation that saw three batteries erupt in flames after side-impact crash tests. Regulators blamed the irregularity on a coolant leak though thus far, no similar incidents have been reported among any Volt owners. The manufacturer plans to remedy the situation by adding extra support to protect the battery during side collisions, adding an extra sensor to keep an eye on coolant levels, and by incorporating an extra bracket atop the coolant reservoir to guard against potential overflows. Vehicles with these enhancements, GM said, passed the tests without any leakage or battery pack damage. Head past the break for the full PR.

Update: Chevrolet has just reached out to us to clarify that adding these enhancements is voluntary, and not mandatory for Volt owners: "These modifications are part of a voluntary customer satisfaction effort. While we will encourage customers to return to a dealership to have their Volt's modified, it is voluntary for them as well."

Researchers increase charging capacity, speed of lithium ion batteries by a factor of ten

Amar Toor — Wed, 16 Nov 2011 05:39:00 EST

It's not every day that we get to write about advancements in battery technology -- much less one as potentially groundbreaking as what a group of engineers at Northwestern University claim to have pulled off. In fact, Professor Harold Kung and his team say they've successfully managed to increase both the charging capacity and speed of lithium ion batteries by a factor of ten. The key, according to Kung, is the movement of the lithium ions nestled between layers of graphene. The speed at which these ions move across a battery's graphene sheets is directly related to how fast a device can recharge. To speed up this process, Kung decided to poke millions of tiny, 10-20nm-sized holes into a mobile battery's graphene layers, thereby providing the ions with a "shortcut" to the next level. As a result, Kung's perforated batteries were able to charge ten times faster than traditional cells, going from zero to hero in 15 minutes.

Not satisfied with that achievement alone, Kung and his squad then set about increasing their battery's charging capacity, as well. Here, they increased the density of lithium ions by inserting small clusters of silicon between each graphene slice. This approach allows more ions to gather at the electrode and, by taking advantage of graphene's malleable properties, avoids some of the silicon expansion problems that have plagued previous attempts at capacity enhancement. The result? A battery that can run on a single charge for more than a week. "Now we almost have the best of both worlds," Kung said. "We have much higher energy density because of the silicon, and the sandwiching reduces the capacity loss caused by the silicon expanding and contracting. Even if the silicon clusters break up, the silicon won't be lost." There is, however, a downside, as both charging capacity and speed sharply fell off after 150 charges. But as Kung points out, the increase in charge retention would more than make up for this shortcoming. "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium-ion batteries on the market today," he told the BBC. For more technical details, hit up the links below.

College students unveil the Kiira EV, Uganda's first electric car (video)

Amar Toor — Fri, 04 Nov 2011 00:23:00 EST

Take a good look at that lime green hornet pictured above, because it may just herald the dawn of a new era in Ugandan transportation. Known as the Kiira EV, this plug-in was designed by students at Makerere University in Uganda, where electric cars, as you might imagine, are something of a rare commodity. In fact, local media outlets are heralding the Kiira as the first EV ever produced within the central African country, and it's not too shabby, either. On Tuesday, after nearly three years of development, the two-seater successfully completed its first test run, reaching a top speed of 65 kilometers per hour and nimbly making its way up a 55-degree incline. According to Paul Isaac Musasizi, who oversaw the project, the Kiira is capable of maxing out at a speed of 150 kilometers per hour, and can run for up to 80 kilometers on a single charge. Aside from its steering wheel and other accessories, every other component was designed and constructed domestically.

Perhaps more important than the Kiira EV's specs, however, is what it symbolizes for Uganda. "When we started the project, we wanted to demonstrate that Uganda has as good talent as that in the US or Germany," Musasizi told Uganda's Daily Monitor. "Now that this is over, we expect and want it to be taken up." It remains to be seen whether the Kiira actually enters production anytime soon, but Musasizi says his team is already working on a 28-seat EV for public transportation, underscoring their commitment to bringing green technology to their country. Hum past the break to see video of the momentous occasion, along with coverage from Uganda's NTV.

Nissan's new charging technology will juice your EV in ten minutes, ten years from now

Amar Toor — Tue, 11 Oct 2011 09:14:00 EST

Nearly a month after unveiling its revamped quick charger, Nissan has now announced that it's working on new technology that would make EV charging... well, quicker. A lot quicker. Developed alongside researchers from Japan's Kansai University, the manufacturer's approach would allow drivers to fully charge their plug-ins in just ten minutes, without taking any toll on a lithium-ion battery's storage or voltage. Nissan says it could achieve this by tinkering with a charger's capacitor -- more specifically, by replacing its carbon electrode with one based on a composite of tungsten oxide and vanadium oxide. Industry insiders, however, say this technology may not reach the commercial level for another ten years -- substantially longer than ten minutes.

Researchers use graphene and tin sandwich to make better battery electrodes

Michael Gorman — Wed, 03 Aug 2011 13:20:00 EST

Graphene, that microscopic chicken wire made of carbon atoms, has a great many theoretical uses. Among these is to improve Lithium-ion battery technologies, and the big brains at the Lawrence Berkeley National Laboratory have created a graphene and tin composite material for use in battery electrodes. When it's baked at 572 degrees Fahrenheit (300 degrees Celsius) the tin turns into nanopillars that widen the gap between the graphene layers. The greater volume of tin provided by these tiny towers improves electrode performance (read: faster charging), and the flexibility of the graphene prevents electrode degradation. Naturally, current prototypes can only maintain capacity over 30 charge cycles -- as opposed to the hundreds required for commercial applications -- so some serious improvement has to happen before we see it strut its stuff in any phones or EVs. This leaves us, once again, extolling the virtues of graphene, but lamenting its exclusively academic application.

Suzuki unveils Every electric van, bead curtains sold separately

Amar Toor — Mon, 18 Jul 2011 13:24:00 EST

Just when you thought the electric van couldn't get any more stylish, Suzuki went out and raised the bar even higher, with its Every van -- a prototype plug-in that has state felony written all over it. Following in the wake of Mitsubishi's Minicab i-MiEV, this love bus is powered by a lithium-ion battery that can be fully juiced in about five hours, with a cruising range of up to 62 miles. It's also a good 400 pounds heavier than its gas-powered predecessor, though, as Integrity Exports explains, its cargo capacity remains fixed at around 550 pounds. For now, Suzuki is sending out just 13 vehicles to a handful of Japanese dealerships, in the hopes of testing the market before a potential widespread launch. No word yet on when that could happen, but Japan's soccer moms and airport shuttle drivers must be licking their chops.

Car2go brings North America's first all-electric carsharing program to San Diego

Amar Toor — Thu, 14 Jul 2011 10:18:00 EST

When we tried out car2go's carsharing program earlier this year, we knew it was only a matter of time before the service rolled out to other parts of the country. Little did we know, however, that it would be doing so atop a flotilla of EVs. Yesterday, the Daimler subsidiary announced that San Diego will be the next city to adopt car2go, making it the first in North America to boast a completely electric carsharing system. The program will kick off sometime before the end of this year, when 300 Smart Fortwo plug-ins storm the city, each powered by a 30 kW electric propulsion system and a lithium ion battery that promises to last for up to 84 miles on a single charge. Whenever the cars run out of juice, drivers will be able to recharge at any of the 1,000 Blink EV charging stations (due to be installed by the end of 2011), before heading off to windsail, buy white linen pants, or whatever people do under perennial sunshine. Curiosity piqued? Steer past the break for the full press release.

OSU Buckeye Bullet 2 sets new battery-powered speed record

Ben Bowers — Wed, 25 Aug 2010 06:42:00 EST

Ohio State's Buckeye Bullet 2 has just set a new battery-powered vehicle record after hitting a speed of 291 mph averaged over two separate runs done back-to-back in opposite directions. Yes, it's technically slower than the two-way land speed record of 300.992 mph the original Bullet set back in 2009, but that car was powered by hydrogen fuel cells. This year's model instead was developed in partnership with boutique Monaco-based electric car manufacturer Venturi and replaced the fuel cells with lithium-ion batteries from A123 Systems. It's also apparently a testing prototype for a new car that's coming in 2011. Will that car hit these kind of world record speeds? Probably not, but we're not letting that dash our newly formed geek fantasy of seeing it drag against a Tesla.

Hitachi claims secret chemical formula will improve battery cathodes, double longevity

Sean Hollister — Wed, 07 Apr 2010 02:49:00 EST

Before lithium-ion batteries, portable gadgets were a nightmare, forcing road warriors and Discman-toting teens to either swap disposable cells or deal with rechargables that (with few exceptions) were tricky to recharge. Of course, Li-ion batteries also have a downside: as laptop and cell phone users have no doubt found out, they too become disposable before long. One reason why is that acid in the electrolyte can corrode the cathode material -- and now, Hitachi claims it's found a way to strengthen its own. Using an undisclosed combination of elements to replace some of the manganese used in the company's cathodes, Hitachi claims they can strengthen their crystalline configuration to resist acid, reduce cost, and best of all, double the usable life of a lithium-ion cell to about ten years. We've heard similar claims before, of course, with other battery manufacturers promising us twenty years, but it looks like this technology might make it out of the lab. NEDO, a Japanese government organization, has commissioned Hitachi to bring these batteries to life for industrial applications like wind farms. Cell phones, sadly, will have to wait.

Nissan shows off latest electric car prototype with battery monitoring system, iPhone app

Laura June — Mon, 27 Jul 2009 11:24:00 EST

Nissan's started showing off its latest prototype electric car, based on the Versa. This one will house a 108 horsepower / 206 pound-feet electric motor to drive the front wheels, and a 24 kWh, lithium ion battery pack will be fitted under the floor for storing electricity, with an expected range of 100 miles. To top things of nerd-style, the newest prototype will have a navigation system which will show the current life of the battery, and the mile range its current amount of juice will support, and will boast the ability to download info about nearby charging station locations. And need we say, "there's an app for that?" That's right, Nissan also has a working prototype of an iPhone app making the rounds in Japan which would allow users to communicate with their car remotely and find out the state of the battery's charge. Can this get any cooler?
