Battery Weight

• Future dismounted warfighter expected to carry
  more than 20 lbs of batteries for a 4 day mission
• Future equipment may require 100s of Watts
• Laser rangefinders/designators
• Micro-climate cooling
• Communications networks

Power Source Needs

• Today
• Disposable batteries 200-350 W-hr/kg
• Rechargeable batteries 150 W-hr/kg
• Future
• 500 W-hr/kg
• Hybridization or other new approaches likely
  necessary to meet high specific power needs

Wearable Power Prize

• Objective is a power system weighing 4 kg
  providing 20 Wavg continuously for 4 days
• Attaches to a garment
• Provides high power (200 W) output for minutes at
  a time plus operates at part-power
• Fully integrated controls for autonomous
  operation
• Addresses key technical challenges to reducing
  weight of carried batteries by 50 for future
  ground-based warfighters

Program Details

• The first DDRE Prize topic
• Authority given to DDRE and service executives
  under FY07 Defense Authorization Act
• Authority formerly resided with DARPA
• Announced 6 July 2007
• Final competition starts with 3 day bench test of
  all competitors, those surviving proceed into 8
  hour field test powering a variety of civilian
  equipment as surrogates for military equipment.
• Prize Purse 1st- 1M, 2nd-500K, 3rd-250K
• Prize Team OSD-DUSD(LABS), OSD-DUSD(ST), ARL,

Program Goals

• 20 W average power with 200 W peaks for up to 5
  minutes, also must operate at part power
• Average power reqt drives energy density
• Peak power reqt drives energy storage component
• Part power reqt drives power energy control
  optimization
• Output is both 14 Vdc and 28 Vdc
• Demonstrate capability of multiple output
• Follow-on development can tailor to specific
  mission needs
• Prize approach invites innovation from
  non-traditional sources
• Component technologies exist or are in
  development
• Dont have to develop new materials or other
  long-term research to meet the goals
• Optimize the integration of components and power
  management

10
Final Competition

• Targeted for October 2008. Likely in desert
  environment.
• Competition goals
• Must demonstrate significant technical
  achievement through simple, verifiable means
• Must provide an interesting media event to
  generate enthusiasm for this topic and others to
  follow
• To satisfy both criteria a two stage event was
  chosen
• 88 hours of static bench testing
• monotonous, but drains the bulk of the energy
  from each system under a controlled standard load
  profile for each system
• 8 hours of field test with the system worn by a
  team member traversing a course with a variety of
  stations with different loads
• Interesting to competitors and media, and
  provides a finish line competitors must cross
  with the system still operating to win
• No refueling between tests

11
Determining the Winner

• Systems still operating at the completion of the
  field test are eligible to win
• Each system has its official weight assigned
  from the first day weigh-in
• The system crossing the finish line with the
  lowest weight (less than 4kg) wins
• Second and third places determined accordingly
