WASHINGTON A battery developer is claiming its technology can extend the range of hybrid electric vehicles.
Technology Research Laboratories Inc. (TRL, Research Triangle Park, N.C.) claims its battery technology can extend the range of hybrid electric vehicles to 75 miles or better per charge. The company claims its battery operates on physical chemistry principles different from conventional lead-acid batteries, and is made almost entirely of carbon and plastic materials.
The company said it is initially targeting the "plug-in" hybrid-electric car market which has so far failed to mesh gears due to unreliable and expensive power sources. Battery disposal also remains an issue. TRL claims its testing showed that a four-passenger electric car be powered by less than 1,000 pounds of its batteries and could travel up to 100 miles on a single charge "depending [on] speed and road conditions."
Total usable energy is 25 kW/hour, TRL said.
Battery life, weight and cost have combined with a lack of battery charging capacity to slow consumer acceptance of electric cars. TRL is claiming a weight power density for its battery technology of up to 80 W per pound with continuous use and up to 200 W per pound at peak use. Volumetric energy density was about 2 kilowatt hours/feet3.
