EnerDel and Think Global Demonstrate Operational Battery Pack in Th!nk City Vehicle - VIDEO ENHANCED

FT. LAUDERDALE, FL - June 9, 2008: Ener1, Inc. (AMEX:HEV), an energy storage solutions company, today reported that its lithium-ion battery subsidiary, EnerDel, has installed and demonstrated a fully functional lithium-ion battery pack in a Th!nk City electric vehicle at its manufacturing facility in Indianapolis. The integration of the battery pack into a Th!nk City EV was completed ahead of the schedule previously announced by EnerDel. The successful completion of this milestone indicates that EnerDel is on schedule to meet the year-end timetable for volume production under its supply agreement with Think Global of Oslo, Norway.

EnerDel delivered three functional 27 kWh lithium-ion battery packs to Think Global earlier this year for testing. Both companies are working to meet the scheduled roll-out of pre-production units over the next three months.

"This is a very exciting program to be involved in, with an aggressive time to market schedule," commented EnerDel CEO Ulrik Grape. "Our collaboration with Think to develop a battery solution for the leading electric vehicle worldwide, the Th!nk City, has been rewarding. A lot of work remains both in terms of testing and evaluation, but we anticipate that we will be able to meet the schedule set by our supply agreement to begin production of integrated battery packs by the end of this year."

"We are very pleased with the progress EnerDel and Think have made on the lithium-ion battery solution for the Th!nk City vehicle," said Think Global CEO Jan-Olaf Willums. "EnerDel has achieved an important milestone and met our expectations so far. We are confident that the project is on schedule to introduce the EnerDel battery in production vehicles by the end of the year."
