Abstract
A charge state calculation device includes a detection means for detecting the voltage and/or the current of a battery, a charge state calculation means for calculating the charge state of the battery, a full charge detection means for detecting the full charge of the battery, a correction value calculation means for calculating, when the full charge of the battery is detected, a correction value for correcting the charge state to the charge state of 100%, a correction means for correcting a charge state by the correction value, and a display means for displaying the charge state thus corrected by the correction means. The correction value calculation means updates the correction value only when the full charge of the battery is detected, and maintains the updated correction value until next time the full charge of the battery will be detected.
