GM Defense introduces battery electric technology for future military platforms

General Motors' defense subsidiary, GM Defense, is making significant strides in advancing military technology by harnessing the potential of GM's innovative Ultium Platform propulsion architecture. This cutting-edge system is currently undergoing rigorous evaluation and testing, with the aim of revolutionizing power, range, and scalability beyond any of GM's previous hybrid or extended-range electric vehicle technologies.

The Ultium Platform's key strength lies in its adaptability and scalability. It can accommodate various battery chemistries and cell form factors, making it highly versatile and future-proof. This flexibility allows for seamless integration of new technologies as they become available, ensuring that the platform remains at the forefront of innovation.

By leveraging its parent company's battery expertise, GM Defense is well-positioned to address the Department of Defense's (DoD) complex energy and energy storage challenges. The ongoing research and development in this new initiative will provide crucial insights into the performance and design considerations necessary when batteries are subjected to more dynamic and high-power operations than typical civilian applications.

The Office of the Under Secretary of Defense for Research and Engineering's Operational Energy Capability Improvement Fund (OECIF) plays a pivotal role in supporting the development of these advanced power and energy technologies. This support is instrumental in providing the DoD with cutting-edge capabilities and ensuring that power and energy constraints do not hinder military operations.

Steve duMont, president of GM Defense, emphasizes the potential benefits for the Department of Defense, stating, "The Department of Defense can benefit from billions of dollars in GM investments to develop and manufacture transformative battery technologies." He further explains that these technologies offer significant potential to enhance operational capabilities, both in tactical situations and at installations worldwide. duMont expresses GM Defense's enthusiasm for supporting this crucial project and assisting in the transition of these technologies to global defense and government customers.

The University of Texas at Arlington (UTA) is collaborating with GM Defense on this project through its Pulsed Power and Energy Lab (PPEL). David Wetz, a professor of electrical engineering at UTA and director of the PPEL, expresses excitement about working with GM Defense to test the Ultium Platform and determine its potential for future warfighting applications. He highlights PPEL's long-standing relationship with the DoD and the Office of Naval Research in testing the limits of batteries used in high-power applications, positioning them uniquely to evaluate this technology and make recommendations for future use cases.

Peter Crouch, dean of UTA's College of Engineering, underscores the importance of this collaboration, stating that it not only improves the nation's military capabilities but also contributes to workforce development efforts. This partnership helps produce the next generation of engineers capable of solving complex national problems.

GM Defense's involvement in advancing battery technology extends beyond this project. The company has previously announced its participation in the Defense Innovation Unit's Jumpstart for Advanced Battery Standardization (JABS) project. Similar to the EEVBEDE initiative, JABS aims to evaluate and test high-voltage battery systems to optimize commercial technologies for military applications. As part of this project, GM Defense provided a prototype battery system based on GM's Ultium Platform and demonstrated mission power capabilities by integrating a high-voltage battery pack into a light tactical utility vehicle.

The insights gained from the JABS project will inform the integration requirements for future battery-electric defense solutions, further solidifying GM Defense's position at the forefront of military technology innovation.

GM Defense LLC, as a subsidiary of General Motors, brings to the table decades of proven performance and billions of dollars invested in independent research and development. The company leverages GM's world-leading capabilities in global design, engineering, and manufacturing to deliver integrated vehicles, power and propulsion systems, and autonomy and connectivity solutions to global defense, security, and government markets. This unique position allows GM Defense to offer exceptional reliability in its technologies, backed by the extensive resources and expertise of its parent company.
