| 摘要 |
This charge state calculation device is provided with a detection means for detecting the voltage and/or the current of a battery (20), a charge state calculation means for calculating the charge state of the battery (20) from the values detected by the detection means, 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 (20) is detected, a correction value for correcting the charge state calculated by the charge state calculation means to the charge state of 100%, a correction means for correcting a charge state calculated by the charge state calculation means by the correction value, and a display means for displaying the charge state thus corrected by the correction means, wherein the correction value calculation means updates the correction value only when the full charge of the battery (20) is detected, and maintains the updated correction value until next time the full charge of the battery will be detected. |
