LED lighting remains the hottest area of green patent litigation, with several complaints filed in the last several weeks. Green patent complaints were recently filed in the areas of advanced batteries and solar powered lighting as well.
U.S. researchers have developed a high-performance, solid electrolyte for use in energy-dense lithium ion batteries that they say is safer than existing liquid electrolytes and could lead to batteries that are five to 10 times more powerful than existing batteries.
While lithium-ion batteries typically utilize liquid
I have been driving a Chevy VOLT for a year and a half. I have more than 26,000 miles on it, and have used 100 gallons of gasoline. That works out to more than 250 mpg. Of course, I have been charging the VOLT at home every night, and at the office during the day but my electric bills at both places are not noticeably higher. It would be nice if the electric range were a bit longer
Despite being in the midst of a financial apocalypse, California continues to find money to support the sale of electric vehicles. The California Air Resources Board just approved an additional $27 million in incentives to spur sales of hybrid and electric cars and trucks. The car rebates ($2,500 per vehicle) will put the price tag of the Leaf and Volt a bit closer to the price
Nissan’s electric car LEAF has been named Car of the Year at the ongoing Tokyo Motor Show, which runs until Sunday, December 11th.
The model has been successful thanks to its efficient lithium-ion batteries and high performance motor. It also features an on-board IT system that can be
Lithium-ion batteries are everywhere these days. From cellphones to electric cars, they dominate the market for rechargeable devices. One of the main challenges faced by the electric vehicle industry is related to the energy density of electric car batteries.
Electric cars are not a new concept in the automotive industry. They were around before the pre-eminence of the internal combustion engine in the 1890s. They were introduced again in the United States in the 1990s with GM’s EV1, but were dropped when GM decided they are unprofitable. Now the
The global market for electric motorcycles and scooters is expected to surge, with the number of vehicles projected to jump from 17 million in 2011 to more than 138 million by 2017, according to a new report.
The two-wheel electric vehicles, which are already
I recently learned of a compelling instance of U.S. government-funded clean tech research translating into widely commercialized technology through green patent licensing.
Argonne National Laboratory announced last month that LG Chem and General Motors had completed licensing agreements
Electric vehicle batteries don’t deal well with heat. Like the Lithium-ion battery in your laptop, if the battery in your EV overheats, it can shorten its lifespan or even cause it to simply stop working. While there haven’t been as many examples of spontaneous combustion in Li-ion batteries in electric vehicles as there have been in
The 2012 Department of Energy budget submitted to Congress on Monday includes a 20-page section on Vehicle Technologies (VT), and nearly every word of it refers to vehicle electrification. In language of funding dollars, the VT budget jumps by 80 percent from $325 million to $588 million.
The majority ($229 million) of the VT
Tomorrow, the automobile industry will have yet another chance to roll out their latest and greatest concepts when the annual Qatar Motor Show kicks off in the nation’s capital of Doha. While there is no doubt that the show will feature some very interesting automobile concepts, one of the more exciting to debut on the showroom floor is what automobile enthusiasts have taken to
There has been considerable buzz about electric vehicles this week. So let’s have a look at the latest EV-related news.
BMW
The German auto manufacturer announced an investment of 400 million
The advanced battery market is about to get much busier thanks to demand from electric vehicles, and an innovative program to capture energy from subway cars could cause a further surge. The Southeastern Pennsylvania Transportation Authority (SEPTA) won a
