PROBLEM TO BE SOLVED: To provide a battery remaining amount display device capable of reducing an error in displaying a remaining amount. SOLUTION: The battery remaining amount display device 1 is structured by including a charging/discharging current detecting device 10, a battery voltage detecting circuit 12, a charging current detecting circuit 14, a battery capacity calculating circuit 16, a charging/discharging current integrating circuit 18, an integration canceling circuit 20, and a battery remaining amount display part 22. The battery remaining amount display device 1 displays the remaining amount of a battery capacity by the battery remaining amount display part 22 by performing an integration process of the charging/discharging current by the charging/discharging current integrating circuit, 18 when the battery capacity is not more than a predetermined value and charging efficiency is high, and does not display the remaining amount when not in the above case and the charging efficiency is low. |
