Light Electric Vehicles Company (LightEVs) signed a world-wide exclusive technology agreement with EEStor, Inc to provide electric vehicles and propulsion systems using EEStor’s Electric Energy Storage Units (EESUs) (earlier post) for the two- and three-wheeled vehicles markets.
The EEStor EESU—a high-power-density multi-layered barium titanate ceramic ultracapacitor—is expected to provide energy densities of more than 450 Wh/kg and more than 700 Wh/L; charge in minutes; and have extremely long life. They are expected to deliver high current without loss of efficiency or excess heat, and they should operate at optimum efficiency over a wide range of ambient temperatures. They are to be configurable for any output voltage that optimizes vehicle performance, and to maintain that output voltage at a constant level over the span of each discharge cycle. Production is now expected to start mid-2009.
LightEVs expects to offer a variety of electric propulsion systems for use in electric bicycles, scooters, motorcycles, and three-wheeled vehicles in partnership with existing manufacturers and under its own brands.
We are planning an electric bicycle that will have a one kilowatt-hour EESU weighing less than five pounds which should provide approximately 100 miles or more of range, and we are considering a three-wheel two-passenger electric vehicle which could offer EESU options permitting ranges from about 120 miles to over 500 miles on a single charge, and a top speed of over 85 mph.—John Stephens, Executive Vice President, LightEVs
In January, Lockheed Martin signed an exclusive international rights agreement to integrate and market Electrical Energy Storage Units (EESU) from EEStor, Inc., for military and homeland security applications. (Earlier post.)
In 2007, Canadian electric automaker ZENN Motor Company took an initial 3.8% equity position in EESTOR. Under its technology agreement with EESTOR, ZENN holds certain worldwide exclusive licenses for EEStor’s storage units for new small and medium-sized low-speed and highway-capable vehicles (up to 1,400 kg curb weight). ZENN also holds worldwide exclusive rights for EEStor units for the conversion of any used internal combustion passenger vehicle to electric drive.
