Vehicle electric power management apparatus, vehicle electric power management system, and vehicle electric power management program

摘要

A vehicle electric power management apparatus 1 calculates a distance from a facility 2 to a destination, from received vehicle-change request information. Distances through which vehicles 3 parked at the facility 2 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 3 can each further travel on beyond the destination away from the facility 2 is additionally calculated and this information is transmitted. After the selection of the next-useable vehicles 3 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 3 that a user has used to arrive at the facility 2, and incentive information are calculated and displayed at the computer.
