ABSTRACT:
A method and apparatus is disclosed for charging lead-acid batteries which comprises periodic voltage sweeps to determine the charging voltage that should be used for the battery and then adjusting the charging voltage in accordance with that voltage sweep information so as to ensure that a highly efficient charging process is achieved which avoids undue gassing and inherently compensates for factors such as the temperature, type and service life history of the battery and resistance due to the interactive nature of the technique and apparatus. One suitable technique for analysis and adjustment of the voltage sweep data involves analyzing the slope of the current versus the voltage sweep curve so as to determine certain slope values or changes in values.
