Batteries, Power and Energy Systems

Finding more efficient ways to power today’s complex, energy-hungry systems is an on-going challenge. General Atomics Electromagnetic Systems (GA-EMS) specializes in creating power and energy systems designed to meet that challenge and support a wide range of land, sea, and air applications.

Lithium-ion Fault Tolerant (LiFT) Battery Systems

LiFT™
  • Safe, fault tolerant design
  • High power
  • Approved for use and classified by DNV-GL
  • On-hull, at-sea tested
  • Long lifecycle
  • Configurable to suit different form factors and energy storage requirements

LiFT battery systems are modular, high energy density solutions for manned and unmanned submersibles, surface vessels, land vehicles, and airborne platforms. LiFT’s single cell fault tolerance prevents uncontrolled and catastrophic cascading cell failure. This ensures the safety of personnel and equipment, and keeps systems operating through faults to enable mission completion.

Aluminum Power System (ALPS)

ALPS
  • Designed for safe, reliable operation
  • Increased energy density
  • Stable, long shelf life
  • Simple refueling process for the fuel cell
  • Modular and scalable

Designed to provide long endurance capabilities to support underwater vehicles, nodes, and platforms, ALPS utilizes a custom aluminum alloy to provide an energy dense, cost efficient alternative to rechargeable Lithium-ion battery power systems. ALPS’ modular design individually isolates each major component to improve reliability, safety, and ease of refueling.

High Speed Power Generation Systems

Electric Motors and Drives
  • High power density
  • Efficient permanent magnet generators
  • Modular drives for power conversion
  • Significant fuel savings over ship service life
  • Direct couple eliminates gearbox

GA-EMS designs and manufactures High Speed Power Generation (HSPG) systems, including permanent magnet motors, generators, and modular drives, to meet the escalating power demand to support ship services and systems.
