ISE is a global leader in hybrid-electric drive systems and components for clean heavy-duty propulsion.

We specialize in series hybrid-electric drive systems, where the engine is completely decoupled from the driveline and used only to generate electric power. This series hybrid architecture is especially attractive for heavy-duty vehicles that perform large amounts of stop-and-go driving, increasing fuel economy and reducing emissions. Our industry-leading energy management solutions and system components increase power and energy efficiency.
