Abstract
A drivable distance calculation device calculates a drivable distance that the vehicle equipped with the device can travel. The drivable distance calculation device includes a remaining battery capacity sensor which calculates a remaining capacity of a battery installed in the vehicle; and a arithmetic unit which calculates multiple power consumption ratios for different units of driving in accordance with variations in the remaining battery capacity calculated by the remaining battery capacity sensor and calculates the drivable distance based on the remaining battery capacity calculated by the remaining battery capacity sensor and a power consumption ratio selected from among the calculated multiple power consumption ratios.
