An Experimental Investigation to Improve Lead Acid Battery Recharging Algorithms for Environmental Performance

Abstract

Perform functional testing of lead acid batteries to demonstrate potential improvements to battery charging algorithms Rationale -Improving charging algorithms can improve battery lifetime -Current charging algorithms are constant voltage and may only provide for temperature compensation (if at all) -Variable voltage algorithms that also incorporating state-of-charge compensation can improve battery charge operations -Improving battery state of knowledge (charge status) can extend battery usage beyond SLI (starting, lights, ignition) operations to enable silent watch operations Approach -Characterize lead acid battery performance as a function of temperature -Three test phases identified and are being executed -Characterize battery environmental performance (OCV, resistance and capacity tests according to MIL-PRF-32143A) -Controlled alternator charging performance -Vehicle simulation tests
