A navigation apparatus for use in a hybrid vehicle in which an engine and a drive motor are used in combination acquires a current SOC value of a battery, geometry of roads around the vehicle, gradient information, traffic information, learning information, and so forth. A travelable range of the vehicle after the battery is charged is calculated for each of a plurality of various charge times on the basis of the acquired information. The plurality of calculated travelable ranges is simultaneously displayed on a liquid crystal display. It is thus possible to display a minimum charge time required to travel to a destination in a manner easily understandable to a user.
