A $32 million prototype agreement has been awarded by the U.S. Army’s Rapid Capabilities and Critical Technologies Office to BAE Systems for the integration of a hybrid electric drive (HED) system onto a Bradley Fighting Vehicle. The initiative is part of the U.S. Army’s effort to increase vehicle efficiency and boost power generation to support integration of future technologies and greater mobility for combat vehicles on the battlefield.
With partner QinetiQ, BAE Systems will use an existing Bradley Fighting Vehicle as the testbed for integrating the HED technology under the Combat Vehicle Power and Energy architecture and mobility capabilities development program. The integration work will begin this summer.
Incorporation of the system into combat vehicles is planned to increase on-board power, mobility, lethality options and range. HED systems also improve automotive performance and provide drive-by-wire mobility to support autonomy in addition to increased power generation. With minor platform modifications, HED technology can be configured for various vehicles including the Bradley, the Armored Multi-Purpose Vehicle, the M109A7 self-propelled howitzers and the family of multiple launch rocket systems.
QinetiQ is developing the electric cross drive transmission (Modular E-X-Drive), a key component of an HED system for tracked combat vehicles. The technology combines electrical and mechanical components in a novel configuration that is efficiently packaged, incorporates mechanical regenerative transfer of steering power, range-shift mechanisms and permanent magnet motor technology. The QinetiQ Modular E-X-Drive has been tested and proven in a wide range of tracked vehicles and weight classes over the last decade. The designs have completed extensive lab and vehicle tests, including safety certifications.
