Ultracapacitors For Electric Bikes
Posted by Big Gav in eestor, electric bikes, electric vehicles, ultracapacitor
Earth2Tech reports that EEStor has signed another customer for its ultracapacitor technology, an electric bike manufacturer - EEStor to Super Charge Electric Bikes.
We still haven’t seen exactly how secretive EEStor’s ambiguously named Electrical Energy Storage Unit (EESU) works, but the Cedar Park, Texas-based startup has been racking up the technology partners. Light Electric Vehicles Company (LightEVs) says it has signed an exclusive agreement with EEStor to use the EESU in two- and three-wheeled vehicles. This follows partnerships with military-industrial giant Lockheed Martin and electric car maker ZENN. EEStor is aiming to start commercial production of its EESUs sometime in 2009, though its not clear which partners will get first dibs.
According to the Eugene, Ore.-based LightEV’s website, it is working on electric propulsion systems for electric bicycles, scooters, motorcycles, and three-wheeled vehicles, which will be built in partnership with existing manufacturers and under its own brands. John Stephens, Executive Vice President, said in the release that LightEVs plans to use EEStor’s technology to make an electric bicycle with a 100 mile range and is considering developing a three-wheel, two-passenger electric vehicle with a range of up to 500 miles on a single charge and a top speed of 85 mph. Impressive sounding, but we’re still waiting for details on how the technology exactly works and performs.
LightEVs describes EEStor’s technology as a “multilayered barium titanate ceramic capacitor,” and the company has said its units are based on “ultra capacitor architecture.” EEStor expects its technology to provide 10 times the energy of lead-acid batteries at one tenth the weight and half the price.
