Fiskers Claims Against A123 Systems Cut By 89%

April 10th, 2013 | by Nicholas Brown

Fisker Automotive made claims of $140 million against A123 Systems (now called B456 Systems. They moved onto the next letter in the alphabet and used the three numbers after 123) because of the rejection of its supply agreement and alleged breach of warranty obligations. The claims were $91.2 million for damages caused by rejection of its supply agreement, and $48.7 million for a breach of warranty obligations. But most of these claims were rejected


Long Term Test | Lithium Ion Motorcycle Batteries

February 5th, 2013 | by Susanna Schick

Well, the Skyrich is in that special battery home in the sky now, ready to become fertilizer (for real) thanks to the lack of any battery management system (BMS). I ran this battery on my 2009 Yamaha R1 since May 2011, (first reported here) putting about 12,500 miles of mostly city riding on it. So while Skyrich advertises that the battery lasts 2,000 cycles, as opposed to the 3-500 lead acid batteries can take, I only found it to last about 2.5 times as long as the lead acid my bike came with. I didn't count the cycles, I counted the years. The stock battery lasted 1 year. The Skyrich was starting to get weak this winter, but I didn't do the research until after it died. It turns out that with liIon batteries, when it's cold you actually heat it up by turning the key and letting it power the lights for a minute. I did find that although it wouldn't crank on the first try in the cold, it would eventually crank. Unlike lead acid, lithium batteries get stronger as you use them, they "warm up"


Turn Your Prius Into a Backup Generator

Are power outages frequent in your area? Especially long ones? If so, a backup generator makes sense, and a new "Plug-Out Kit" for the Toyota Prius hybrid turns this fuel sipper into a backup generator


Some Authorized Chevy Volt Dealers Cease Selling Hybrid Over $5,100 In Tools

January 3rd, 2013 | by Christopher DeMorro

As any mechanic will tell you, tools aren’t cheap. If you’re the gotta-have-the-best-of-everything kinda person, you could spend $20,000 or more on a toolbox, and JUST the toolbox. So this story regarding some Chevrolet dealerships ceasing Volt sales over just $5,100 in specialized tools is a bit of a head-scratcher


Crippling Lithium-Ion Battery Flaw Revealed

December 28th, 2012 | by Nicholas Brown

The first step to solving a problem is diagnosing it, and in this case, a huge step was taken for electric vehicles. Researchers at Ohio State University discovered that in lithium-ion batteries, lithium-ions accumulate inside a sheet of copper known as the current collector. Lithium-ions should not permanently accumulate on the current collector like this, as they are necessary for battery function, therefore this decreases battery performance, as there will be less lithium-ions available
