(54)System for providing information on power consumption amount of electric vehicle


(57) A high-speed calculation of power consumption provided to a driver to figure out whether an electric vehicle 5 is able to reach a destination can be implemented.
Solution: A system for providing information on power consumption amount of an electric vehicle 5 includes receiving means 11 for receiving a departure point of the electric vehicle 5 and a destination of the electric vehicle 5 from a terminal device; a database which stores a plurality of power consumption amounts required to move between respective two sections, corresponding to a plurality of combinations of two sections, the combinations including a combination of a first section in a predetermined area including the departure point and the destination, and a second section including a second point in the predetermined area; extracting means 12 which retrieves the database to thereby extract a power consumption amount required to travel from the departure point to the destination; and transmitting means 14 for transmitting information on the power consumption amount extracted by the extracting means 12 to the terminal device.
