GA-EMS tests LiFT battery
General Atomics Electromagnetic Systems’ (GA-EMS) Lithium-ion Fault Tolerant (LiFT) battery has successfully completed on-hull demonstration testing on a Special Operations Command (SOCOM) undersea vehicle, it announced on 11 April.
According to the company the battery achieved DNV-GL certification and more than 60 hours of at-sea ‘underway under battery power’ time with no failures.
The LiFT battery system can be used in both unmanned and manned underwater vehicles. It has been designed as a high energy density solution for improving projected vehicle mission capabilities.
The on-hull demonstration testing validated the system’s functionality and verified its capacity to provide the power necessary for submersible propulsion and operation.
Paul Clark, senior manager, LiFT program, GA-EMS, said: ‘Unlike prior Lithium-ion battery technologies, GA-EMS' LiFT battery system offers a single cell fault tolerance to prevent uncontrolled cascading failure. This means the battery is capable of surviving a catastrophic cell failure without propagating to neighbouring cells, ensuring the safety of on-board personnel and equipment.’
