Ener1 First to Integrate Lithium-ion Battery in a Hybrid Electric Vehicle

December 4, 2007

FORT LAUDERDALE, FL – Ener1, Inc., an alternative energy company, has successfully integrated a lithium-ion battery into an operating hybrid electric vehicle (HEV). The company’s automotive battery division, Indianapolis-based EnerDel, exhibited its high-powered lithium-ion battery pack in an operating HEV at the International Electric Vehicle Symposium and Exposition (EVS-23) in Anaheim, Calif., Dec. 2-4.

“We have made a major stride toward providing the power, safety, and affordability that the market has been waiting for,” commented Ulrik Grape, Ener1 executive vice president for Global Sales and CEO of EnerDel. “We believe that ours is the safest high-power lithium-ion battery available for hybrid electric vehicles.”

EnerDel’s engineering team has modified a Toyota Prius vehicle to work successfully with the company’s exclusive battery chemistry and design. Making approximately twice the energy available for the car’s use compared with the existing nickel metal hydride battery is expected to substantially increase performance.

Third-party testing results on the battery’s performance in the Prius are expected to be released during the first quarter of 2008.

EnerDel is scheduled to deliver a prototype electric vehicle (EV) battery to Think Global of Norway in March under a $70 million development and supply agreement. The company has also received a $6.5 million contract from the U.S. Advanced Battery Consortium for development of a plug-in hybrid electric vehicle (PHEV) battery.
