has developed a prototype advanced power management system designed
to provide military tactical wheeled vehicles with substantial
capacity to generate electric power, addressing a critical warfighter
need. When installed in a standard HMMWV the new power system
delivers sufficient electricity to operate electronic mission
systems on board combat vehicles, including subsystems such
as electronic warfare, situational awareness, communications,
and vehicle prognostics and diagnostics, eliminating the need
to operate dedicated generators to power the mission equipment.

Using a permanent-magnet generator, the system delivers up
to 400 amps of 28-volt DC electric power at low engine speed.
Its primary purpose is to provide enough on-board power to operate
significant self-defense, weapon, countermeasures, and route-clearing
systems. Additionally, it provides power for electrified automotive
accessory systems (water pump, engine fans, power steering pump
and, in the future, air conditioning) that previously were belt-driven.
The system produces 400 of 28-volt DC power across the entire
engine operating range, and 30kW of optional 208-volt power
at higher engine speeds.
