Characterizing Battery Rejuvenators Team Shock Therapy: Tim Blake, David Bankhead, Travis McMillen
Presentation outline • Background • Process of Defining the Project • Our Problem Definition/Goal • Test Setups • Procedure • Design Matrix • Future Work
Background • Goal of Acoustic Research Detachment • Create quieter NAVY vehicles • Use lead-acid batteries to power their vehicles • A ship uses hundreds of batteries • Example: LSV-2 Cutthroat • Batteries need to be replaced every 4 years • NAVY wants to improve battery performance
Process of Defining the Project • NAVY • Originally CCCV vs. Pulse • Analyze rejuvenators • Indications of health of battery • University of Idaho • Navy specs not design, need design project!
Project Definition/Goals • Project Definition • Navy needs a reliable way to extend the life of their batteries. • They are considering using battery rejuvenators. • Project Goal • Design a procedure/algorithm that the Navy can use to characterize their rejuvenators.

Procedure Decision Matrix
Future work • Automated control system • Verification of 2 Volt batteries • Quantify Internal resistance of batteries • Compare constant current constant voltage to pulse rejuvenators • First 10 min. of a rejuvenation.
Conclusions • Pulse rejuvenators work • BatteryMINDer works the best • Most important characteristics have been determined in characterizing a rejuvenator • Difference between two batteries pulsing in first 10 min. • Recommend pulse charging for the next charge setup
