Saft to supply Li-ion energy storage for US Army Ground Combat Vehicle program; VL 5U ultra-high-power cells

21 March 2012

Saft’s advanced Li-ion energy storage system will support the technology development phase of the US Army’s Ground Combat Vehicle (GCV) program. As a member of the BAE Systems GCV team which has been awarded a contract for the initial phase of the program, Saft has entered into an agreement to design and build ultra high-power batteries for the vehicle’s hybrid electric drive system.

The vehicle must meet the Army’s rigorous requirements for a highly survivable platform that can adapt to an evolving operational environment. Comprising ultra-high-power, high-voltage VL 5U cells, the Li-ion energy storage system will support the vehicle’s hybrid electric drive system when it is not relying on traditional carbon-based fuels; an example of an operation that would utilize this technology would be silent watch missions.

The VL 5U cells are rated at continuous power of 5,250 W; 2 s pulse at 7,500 W; and 200 ms pulse at 10,000 W.

In addition, the system will provide thermal management and act as a high-power traction motor battery.

The technology development phase of the GCV program is a 24-month program aimed at completing preliminary design reviews in order to begin building prototype systems for the engineering and manufacturing development phase of the program.

This partnership is a testament to BAE Systems’ support of Saft; our company has also supplied batteries for the Non-Line-of-Site Cannon (NLOS-C) and Manned Ground Vehicles (MGV) for the Army’s FCS program. We look forward to furthering our relationship with BAE Systems and upholding our commitment to excellence under this new program.

—Frank Rosenthal, General Manager of Saft’s Space and Defense Division
