Falcon intros lightweight power conversion

Lithium-polymer battery weighs about a third of lead-acid batteries, takes load off mobile military apps

Falcon’s new ultralight lithium-polymer battery pack is designed to lighten the load for military power conversion.

The company’s ED LIB Series 5kVA uninterruptible power supply with lithium-polymer battery system features the first battery certified by the Transportation Department for use onboard mobile armored vehicles and high-mobility multipurpose wheeled vehicles, Falcon representatives said. Hundreds of the rackmount ED-LIB Series 5kVA models are being used by the Army in Iraq and Afghanistan, the company said.

Falcon uses its power conversion system to convert the three-phase, 400-Hz power provided by an auxiliary power unit in the vehicle to a clean, regulated 120 VAC/60 Hz source for onboard computer and communications gear, the company said.

“The Army challenged Falcon to design a lightweight battery pack and the necessary microprocessor-based battery management system for this application,” said Michael Stout, vice president of engineering at Falcon. “With the lithium-polymer battery system weighing 55 pounds, the Army was impressed by the system’s light weight, small size and a stellar backup time of 25 minutes at 2,300 watts — a lead-acid battery equivalent would weight over 150 pounds. Every pound saved is an extra pound of armor on the vehicle and this is vital for occupant safety.”
