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.
