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
5
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

System Benefits
•
•
•
•
34% cable weight reduction for load circuits
carrying higher than 3amps.
20 min @ 4 mph silent operation
80% increase in energy storage density
(baseline: lead-acid)
2X increase in battery life (baseline:3yrs leadacid )
7
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.

M&S Goals
• Provide a highly accurate estimate of vehicle power
consumption
• Determine power required for various mission scenarios
• Calculate silent watch durations for a given subset of
vehicle equipment
• Provide simulation capability to determine
peak/average/low power consumption
• Consider vehicle environmental conditions (temperature,
humidity, shock, vibration, etc.) on both the power
generating equipment and energy storage devices
• Consider automotive constraints (engine RPM, engine
and/or APU fuel consumption, etc.)
• Analyze vehicle degraded modes of operation (e.g. what
happens if APU fails?)
