PURPOSE:To accurately confirm the content of display, and to discriminate the abnormality of display by successively conducting the display of residual capacity and the display of a charging time. CONSTITUTION:Display corresponding to the magnitude of the residual capacity of a battery 6 is performed in a residual-capacity display body 46. When charging is executed to the battery 6 at that time, a charging-time display body 16 conduct its own display while the display content of the residual-capacity display body 46 is confirmed simultaneously. Consequently, whether the content of display is during charging or during discharging can be made sure at a glance. When display by the residual-capacity display body 46 is performed in stepped display and the position of arrangement of the charging-time display body 16 is adjoined to the location A of display of the minimum capacity of the residual-capacity display body 46, the display of the charging time is displayed successively after the display of residual capacity, thus executing display in which both are unified. |
