ABSTRACT:
A method and system (400) for controlling battery charging including applying a predetermined voltage to a battery (500) to be charged, increasing the voltage applied to the battery (500) to a known maximum battery charging voltage, measuring a current supplied to the battery (500) at the maximum battery charging voltage, supplying a predetermined set of constant current charging levels, and setting a charging current level equal to one of the set of predetermined constant current charging levels based on the current supplied to the battery at the maximum battery charging voltage for minimizing an amount of time needed to charge the battery (500) and maximizing a useful life of the battery (500).
