PROBLEM TO BE SOLVED: To reduce the effect of noise in the case of estimating a battery capacity for display, and avoid the circumstance where the noise causes the capacity display not to change from a certain value.SOLUTION: A battery capacity display device includes a battery charged by DC power, a controller which measures a battery voltage, and estimates a battery capacity from the measured voltage, and a display unit that displays the capacity estimated by the controller. The resolution of the measured voltage is sufficiently high compared with the resolution of the display unit. |
