Saft to deliver e6T Li-ion batteries to Lockheed Martin for Joint Light Tactical Vehicle (JLTV) program

16 May 2013

Saft has been awarded a contract from Lockheed Martin for delivery of e6T Li-ion battery systems for the engineering and manufacturing development (EMD) phase of the Joint Light Tactical Vehicle (JLTV) Program.

The JLTV program will produce a family of vehicles capable of performing multiple mission roles that will be designed to provide protected, sustained, networked mobility for personnel and payloads across the full range of military operations. JLTV objectives include increased protection and performance over the current fleet; minimizing ownership costs by maximizing commonality, fuel efficiency, reliability, and maintaining effective competition throughout the lifecycle.

The Saft e6T Li-ion battery system is designed as an auxiliary power source for military vehicles and features an advanced, lightweight design within the dimensions of a traditional lead-acid battery, enabling easy integration into the vehicle. The system provides power for starting, lights and ignition, as well as for silent watch missions, while also providing critical front-line power to recharge personal electronics like night sights and GPS devices.

The e6T battery system includes electronic devices for performance, thermal, and safety management specific to the application. The Battery module contains 21 Saft 6T Li-ion cells connected in a 3P-7S configuration and one Power Control Module.

The 25.5V battery features CANBus communications technology which relays information such as state-of-charge, cell voltages and temperatures, and battery diagnostics.

Saft will deliver 59 batteries in total to Lockheed Martin for vehicle prototypes scheduled for delivery during the 33-month EMD phase, followed by a final competition after which a production contract will be awarded, around 2015. Lockheed Martin represents one of the three competing development teams. If the Lockheed Martin team is selected, Saft would potentially produce e6T Li-ion batteries for JLTV production to take place over an eight year period.

The EMD-phase contract for Saft calls for delivery of battery systems in 2013. The JLTV program allows Saft to further demonstrate the capabilities of its maintenance-free e6T battery system for military ground vehicles, already being demonstrated in the Improved Battery System program for the Marine Corps.
