Title: BATTERY CAPACITY DISPLAY DEVICE AND BATTERY CAPACITY DISPLAY METHOD
Abstract:
In order to provide a battery capacity display device that is capable of performing display which is easily understood by the user and which is based on battery characteristics, namely, where battery capacity is closely related to battery voltage, this battery capacity display device includes: a battery; a storage unit that stores a table in which voltage bands for equally dividing an interval between a full charge voltage of the battery and a prescribed voltage are set, the table associating the voltage bands with battery capacity; a voltage detection unit for detecting a voltage of the battery; a voltage band determination unit for determining the voltage band to which the voltage detected by the voltage detection unit belongs; a battery capacity determination unit for determining battery capacity on the basis of the voltage band determined by the voltage band determination unit and the table stored in the storage unit; and a display unit 20 that displays both information pertaining to the voltage band determined by the voltage band determination unit and information pertaining to the battery capacity determined by the battery capacity determination unit.
