Abstract:

Experiment designs, test data, analyses and results for investigations of constant current and constant potential charging at 125, 75, -10 and 40 F for cells at different initial states of charge are presented. Results of a preliminary investigation of pulse charging at -40 F are also presented. Experiments include test variables of ambient cell temperature, charging period, charging potential, percent input, initial state of charge, cell size and discharge rate depending upon the type of charging method employed. Cells of type BB 412 U and BB 440U were used in these investigations. Analysis of the charging procedures are based upon the percent capacity obtained at the test conditions to that obtained in a normalizing cycle at 75 F. The average of the results obtained at 75 and 125 F following constant potential charges was greater than that following constant current charges over the selected levels of the test variables.
