State-of-Charge Indicator for Zinc-Mercuric Oxide Batteries
Abstract
The feasibility of using a short duration, high current, constant voltage pulse charging technique to predict the state-of-charge of zinc-mercuric oxide cells and batteries was examined. The approach used in the study was (1) determine the test parameters which provided the greatest variation, (2) construct a standard curve for each battery and temperature, (3) test unknown batteries and match their test response to the standard curve, and (4) discharge the unknown batteries to determine their true state-of-charge at the time of the test. The results were extremely encouraging. Even though only a feasibility study, the technique was able to predict the state-of-charge with a standard deviation of only 6.7%.
