The U.S. Army Communications-Electronics Research, Development and Engineering Center’s Command, Power and Integration Directorate Power Division, is developing safe, technically innovative and cost effective solutions to meet the Soldier’s portable and mobile power and energy needs today and into the future.

The Wearable Power System for the dismounted Soldier produces 20W continuous output and 35W peak. It provides similar performance or better than the present Army wearable battery while decreasing the carried battery weight and volume by more than 50 percent for a 20W 72-hour mission. It provides a decrease in weight without loss of capability.

The Wearable Power System is worn in a pouch on a MOLLE or SWIPES vest. The extra fuel cell chemical hydride cartridges are carried in other vest pouches or in the rucksack. The 20W Wearable Power System powers individual Soldier devices or all of a Soldier’s ensemble devices through a power distribution system. The Wearable Power System is part of the Tactical Power Generation Program.

Capabilities:

  • 20W continuous output, 35W peak for 10 min.
  • Enables sustainment of dismounted operations in remote areas
  • Instant start up utilizing built in batteries
  • Built in batteries allow for energy harvesting
  • Single 80Wh chemical hydride cartridge provides 811Wh/kg on a per cartridge basis

Features:

  • Start-up Time: Instant with back-up battery
  • Voltage: 10.0 -16.8 V
  • Energy Density for 24-hour mission: 300Wh/kg
  • Dry Weight: 0.92kg.
  • Dimensions: 7.0 in. x 8.0 in. x 0.81 in. with flexibility to conform to SAPI plate
