Abstract: A vehicle electric power management apparatus calculates a distance from a facility to a destination, from received vehicle-change request information. Distances through which vehicles parked at the facility can travel are calculated and vehicle information on parked vehicles capable of traveling through a distance longer than the distance to the destination are selected as next-useable vehicles in descending order of a residual amount of available battery power. A surplus distance indicating how far in kilometers the selected vehicles can each further travel on beyond the destination away from the facility is additionally calculated and this information is transmitted. After the selection of the next-useable vehicles by a computer of the facility, increment/decrements in the residual amount of available battery power between each selected next-useable vehicle and the vehicle that a user has used to arrive at the facility, and incentive information are calculated and displayed at the computer.

Abstract: System for providing information on power consumption amount of electric vehicle includes receiving means for receiving departure point of the electric vehicle and destination of the electric vehicle from a terminal device; a database which stores a plurality of power consumption amounts required to move between respective two sections, corresponding to 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 which retrieves the database to thereby extract a power consumption amount required to travel from the departure point to the destination; and transmitting means for transmitting information on the power consumption amount extracted by the extracting means to the terminal device.

Abstract: A high-speed calculation of power consumption provided to a driver to figure out whether an electric vehicle is able to reach a destination can be implemented.
