GM’s military vehicle and technology division, GM Defense, has announced a new contract with the Department of Defense’s (DoD) Defense Innovation Unit (DIU) to prototype an energy storage unit to support tactical microgrid and energy management capabilities. The prototype will incorporate GM’s electric vehicle propulsion architecture known as the GM Ultium platform. The new contract follows another DIU contract awarded in the fall of 2022 to provide a prototyping battery system based on the Ultium platform.
“This contract award demonstrates our ability to leverage advanced commercial technologies and investments from our parent company, GM, to reduce warfighter fuel consumption, and lower acoustic and thermal signatures, while providing efficient energy at the tactical edge,” said the president of GM Defense, Steve duMont. “We are proud to win another contract award with DIU, whose mission to accelerate the adoption of commercial technology across the U.S. military aligns with our efforts to transition global defense and government customers to a more electric, autonomous and connected future.”
The new energy storage system will meet the requirements of DIU’s Stable Tactical Expeditionary Electric Power (STEEP) program, which will support tactical microgrid and energy management capabilities in a scalable and adaptable unit, providing an uninterruptible and sustainable power source for mission critical equipment like command and control, communications, radar, and weapons systems. The STEEP energy storage system will draw from hydrogen-powered generators, stationary and mobile electric power, or fuel-powered generators.
The new STEEP contract follows a contract awarded to GM Defense in the fall of 2022 to support the Jumpstart for Advanced Battery Standardization (JABS) project. JABS is designed to standardize battery modules across the DoD, and pave a path forward for future battery advancements and military platform integration. Since the initial contract award last year, GM Defense has expanded to integrate the high-voltage battery into the business’ Multi-Mission and Logistics vehicle.
