GA-EMS to provide LiFT battery system for SAHRV platform


General Atomics Electromagnetic Systems (GA-EMS) has been contracted to deliver its Lithium-ion Fault Tolerant (LiFT) battery system for the semi-autonomous hydrographic reconnaissance vehicle (SAHRV).

The SAHRV is being developed as a small and portable unmanned underwater vehicle (UUV) intended for use in shallow water surveillance applications to scan, detect and identify mines and other obstacles.

GA-EMS has been tasked to design, fabricate, supply and conduct at-sea testing of the LiFT battery system to be used on the SAHRV platform, as part of a collaboration with the US Department of Defense.

GA-EMS president Scott Forney said: “Our modular, flexible LiFT battery systems are designed for integration into a wide range of platforms, and have been successfully tested for use on a manned submersible.

"The goal is to provide a safe, fault-tolerant, high energy density system that achieves the safety certification approvals required for an unlimited ship carry-on capability."

“The goal of this new contract is to provide a safe, fault-tolerant, high energy density system that achieves the safety certification approvals required for an unlimited ship carry-on capability, and to provide the energy needed to maximise mission assurance whenever and wherever the SAHRV is deployed.”

GA-EMS has designed and developed its LiFT battery system for use on on both manned and unmanned underwater vehicles and platforms.

The single-cell fault tolerance of the LiFT battery system helps prevent uncontrolled cascading cell failure, thereby ensuring the safety of on-board personnel, as well as keeping systems operational through faults and ultimately allow completion of the mission.

The LiFT battery system has been approved for use and classified by DNV-GL.
