After being awarded a contract, General Atomics Electromagnetic Systems (GA-EMS) will provide its Lithium-ion Fault Tolerant (LiFT) battery system for a small, portable UUV named the Semi-Autonomous Hydrographic Reconnaissance Vehicle (SAHRV).
Designed to be used on both manned and unmanned underwater vehicles and platforms, the battery system has a number of unique features, such as its single cell fault tolerance, which prevents uncontrolled cascading cell failure, and ensures the safety of on-board personnel.
The single cell fault tolerance also allows for the completion of a mission, by keeping systems operational through faults.
“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,” says GA-EMS president Scott Forney through press release
“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 maximize mission assurance whenever and wherever the SAHRV is deployed.”
The SAHRV UUV is built for scanning, detecting, and identifying mines and other obstacles during shallow water surveillance missions.
GA-EMS is working with the Department of Defense as a part of a team looking to design, fabricate, deliver, and conduct at-sea testing of the SAHRV UUV with the LiFT battery system installed on it.
