  1. Energy Dense Power SystemsField Testing with Power 8 Lithium Ion Battery Box Test Results June 2009 Fridge Freeze 15qt Blood Cooler Performed for SOCOM/Ft Bragg

  2. Test Protocol #1 • Blood Cooler and Lithium Ion Battery Box tested inside lab. No exposure to temperature swings. Ambient temp during test 78-83 F. • Cooler at room temp at start of test. Cooler opened at 4hr intervals (15 seconds) for duration of test. • Fully charged Power 8 Battery Box begins powering Tuesday, June 16th, 8:30 PM. Test terminated Thursday, June 18th, 10:30 PM RESULTS • Cooler draw of 39W-46W @ 3.2 amp, random cycle times, • Internal cooler temp maintained at 40 F, measured with SOCOM supplied temperature probe. Interior walls measure 32-29F with IR temp gauge. • Power 8 Lithium Ion Battery Box operated cooler for 50 hr, over 21% charge remaining at termination of test (Potential additional 12 hr).

  3. Test Protocol #2 • Blood cooler and Lithium Ion Battery Box tested outside in full sun, (exposed to elements). • Cooler at room temp at start of test. Cooler opened at 4 hr intervals (15 seconds) for duration of test. • Fully charged Power 8 Battery Box begins powering Friday June 19th, 8:30 AM, test terminated Sunday June 21st, 10:30 AM. RESULTS • Coolerdraw 37-42W @ 3.1 amp, random cycle times • Internal cooler temp maintained 40 F, measured with SOCOM supplied temp probe. Interior walls measure 29-32F with IR temp gauge. • Power 8 Lithium Ion Battery Box operated cooler for 50 hr, over 9% charge remaining at termination of test. (potential additional 4.5 hr).

  4. Test Protocol #3 • Blood cooler and Lithium Ion battery Box tested outside in full sun, (exposed to elements) Same as Test Protocol #2. • One 60w solar panel connected to Power 8 to supplement energy consumption of blood cooler. • Fully charged Power 8 Lithium Ion Battery Box begins powering Monday June 22nd, 8:30 AM, test terminated Monday June 22nd, 8:30 PM. RESULTS • Maximum solar charge input recorded 39W, (solar charge limited to cloudy/overcast conditions). • On average 7 sun hours at 39W are needed a day for indefinite operation. • Even with only 4 hours of solar panel operation a day, run-time would be extended to 109 hours.

  5. CONCLUSIONS • Power 8 Lithium Ion Battery Box is completely compatible with portable blood cooler provided by SOCOM. • Power 8 will dramatically increase runtime of tested unit, (reduced monitoring of power supply, and reliance on recharge) • Power 8 is significantly lighter than lead acid systems available, (increased portability for field personnel) • Use of solar recharge can greatly reduce need for grid connectivity.

  6. ADDITIONAL BENEFITS • Power 8 units are UN/DOT compliant for commercial flight (nonhaz) perfect for first responders. • Power 8 units are capable of receiving all or part of existing power from BA2590 and BA5590.
