Abstract
A power control device and the operating method thereof are provided. The present invention obtains the battery inner resistance by using the battery inner resistor detecting loading circuit. The voltage drop occurred in between the positive pole end and the negative pole end is calculated with such method when the power consuming device in the portable electronic device is operating. Thus, the power storage of the battery can be accurately detected.
