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. (more…)
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 (more…)
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 (more…)
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 (more…)
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 (more…)
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.
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 (more…)
