METHOD AND APPARATUS FOR GENERATING ROUTE GUIDANCE FOR ELECTRIC VEHICLE USING BATTERY POWER STATE INFORMATION

A navigation apparatus generates route guidance for an electric vehicle based on information on a battery power state of the electric vehicle. The navigation apparatus includes a driving route generating unit, a battery information acquiring unit, a mileage calculating unit and a driving information setting unit. The driving route generating unit receives destination information and generates a driving route corresponding to the destination information. The battery information acquiring unit obtains information about a minimum remaining amount of a battery of the electric vehicle input by a driver of the electric vehicle. The mileage calculating unit calculates an available driving distance of the electric vehicle based on a current remaining amount of the battery and the minimum remaining amount of the battery. The driving information setting unit sets information related to the driving route based on the available driving distance, and displays the information via a display apparatus.
