Purpose

• The purpose of the Advanced Mobile integrated
  Power System (AMPS) is to rapidly develop a
  configurable power system capable of supporting
  electrical power power management requirements
  to integrate Vetronics, C4ISR, and embedded
  simulation capabilities into FCS platforms,
  including robotic Unmanned Ground Vehicles (UGV).
  

The AMPS will capitalize on prior and parallel
research investments

Current Technology Barriers

• Limited space and weight for electrical power and
  energy storage components
• Emerging commercial 42 volt components need to be
  military rugged
• Lead acid batteries do not have the energy
  density to support the vehicle mission
• Present electrical systems are energy wasteful
  and are not controlled to support the vehicle
  mission

6
Solutions

• Develop 42 volt ruggedized components and systems
  that are smaller and lighter compared to 28 volt
  systems
• Advanced chemistry batteries and fuel cells
• SMART Architecture / components to allow
  management of dynamic power and graceful
  degradation

7
System Benefits

• 34 cable weight reduction for load circuits
  carrying higher than 3amps.
• 20 min _at_ 4 mph silent operation
• 80 increase in energy storage density (baseline
  lead-acid)
• 2X increase in battery life (baseline3yrs
  lead-acid )

8
Warfighter Benefits

•      
• Provide silent movement, extending the
  perception of the dismount soldier
• Increase reconnaissance, surveillance, and
  target acquisition capabilities by facilitating
  state of the art electronics usage.
• Decrease logistic burden and combat load due to
  increased battery life.
