US Army’s Fuel Efficient Ground Vehicle Demonstrator (FED) Leverages Kollmorgen’s Low Voltage Power Generation Platform to Deliver More Power

RADFORD, VA - February 18, 2011 - Kollmorgen is unveiling a new in-line variant of the company’s low voltage Power Generation System. This lightweight solution is being used by the United States Army to deliver on board vehicle power (OBVP) generation to their Fuel-Efficient Ground Vehicle Demonstrator (FED). The Kollmorgen system enables the FED Alpha vehicle to provide 30kW of power at 28VDC, over a wide engine operating band. The Kollmorgen low voltage platform will be demonstrated on a commercial truck with a belt driven generator and a display of the Integrated Starter Generator (ISG) during the Winter Association of the United States Army (AUSA) conference from February 23 - 25, 2011, in Fort Lauderdale, FL.

“The Kollmorgen power generation platform is uniquely capable of generating all of the power needed to support the tactical demands of today’s military vehicles from a low voltage system,” says Brandon Edlefsen, Director of Kollmorgen’s Vehicle Electric Power Business Unit. “It has reduced the weight of the TARDEC FED ALPHA vehicle by approximately 150 lbs. when compared with high voltage power generation systems. Those weight savings, combined with the industry leading 90 plus percent efficiency of Kollmorgen’s power generation system, play a large role in the vehicle’s significant fuel savings.”

The FED Alpha is the first of two vehicle projects that the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC) is developing to showcase fuel efficient technologies, while maintaining tactical vehicle capability equivalent to an up-armored HMMWV. Maximizing fuel efficiency not only saves the Army money in direct fuel costs, but it can also help save soldiers lives by reducing the frequency of driving fuel convoys into highly targeted combat locations.

Kollmorgen’s low voltage power generation platform consists of flexible power electronics that support multiple generator configurations and mild hybrid capability. The generator system used in the FED vehicle is an in-line ISG 28 VDC, 30kW liquid cooled generator with three 10 kW air cooled power electronics modules, which communicate on J1939 software protocol. The low voltage platform also includes a belt driven air cooled generator that produces 30kW at 28VDC, utilizing the same controllers as the ISG system.

Kollmorgen is a leading provider of power generation and motion systems for OEMs around the globe. Through world-class engineering knowledge, industry-leading quality and deep expertise in linking and integrating standard and custom products Kollmorgen delivers breakthrough solutions that are unmatched in performance, reliability and ease-of-use, giving vehicle and machine builders an irrefutable marketplace advantage.
