ABSTRACT:
A method for determining an effective voltage of a battery includes detecting a battery voltage at a predetermined interval, and counting a number of times the battery voltage is detected within a series of predetermined voltage ranges. The method also includes calculating a ratio of the change of the counted number with respect to a change of the battery voltage, and determining a first peak point of the calculated ratio.
