Abstract
A dynamic battery charging method for use in a battery charger configured to charge a lead acid battery, including marking a time when battery charger switches from Constant Current (CC) phase to Constant voltage (CV) phase to establish CV Start Time; starting at CV Start Time; calculating Delta Current by subtracting current measurement at particular time interval from previous current measurement at an earlier time interval; terminating CV phase once Delta Current is less than or equal to a particular Delta Current current level OR once the battery charger operating current drops below a particular battery charger operating current; marking CV Finish Time; switching back to another CC phase once CV phase is terminated; and staying at another CC phase for a time period equal to the CV Finish Time minus CV start Time OR until lead acid battery reaches CV voltage plus an additional voltage amount to complete charging.
