ISE Corporation, CA
(Hybrid Electric Powertrains)
ISE Corporation ("ISE") is a supplier of integrated hybrid-electric drive systems and control software for large buses and trucks. ISE's controllers and software govern and optimize the use of energy in its hybrid-electric drive systems, which use electric power for vehicle propulsion but also generate onboard power using conventional engines. ISE combines its control systems with electric motors, generators, and other components purchased from various suppliers and partners, integrating all of the parts into complete "ThunderVolt®" hybrid-electric drive systems that ISE sells to bus and truck manufacturers. In addition to its principal business as a supplier of fully integrated drive systems to vehicle manufacturers, ISE installs its systems into buses, trucks, and other vehicles on a smaller scale, generating additional revenue and demonstrating its drive systems in an ever-expanding variety of vehicle models.
