Under the terms of the contract, ISE will source ultracapacitor cells for use in its ultracapacitor energy storage systems (ES Systems) exclusively from Maxwell through December 2011 and Maxwell will exclusively purchase ultracapacitor based energy storage systems from ISE for sale or distribution by Maxwell and its affiliates into the heavy duty vehicle market through December 2011.

ISE’s Ultra-ETM ES System combines ISE’s energy storage system technology and Maxwell’s ultracapacitor cell technology. Included in the technology design is a battery management system that monitors each cell.

The system is fully integrated with thermal management through active-liquid cooling, pre-charge isolation management, high voltage and current sensing feature, main contactors, system diagnostics and prognostics and environmentally sealed to IP67 / IP6k9k specifications.

ISE’s Ultra-ETM ES Systems is interfaced with a range of high duty cycle applications around the world such as mining, heavy-duty trucking, rail, and smart grid energy/power management systems.

Rick Sander, CEO and president of ISE, said: “In 2001, we signed a strategic development and supply agreement and began working with Maxwell. Today’s agreements extend our alliance, provide additional validation of our ES Systems, and represent a significant milestone in our growth strategy.

“Partnering with Maxwell Technologies provides us with access to its extensive sales force, distribution system and installed base into geographies we haven’t yet penetrated.”
