摘要

PROBLEM TO BE SOLVED: To generate information related to the efficiency of electric consumption in an electric vehicle, on the basis of information obtained from the electric vehicle.SOLUTION: When an electric automobile 3 reaches a communication area of a radio communication unit 42, an information generation device 4 receives and acquires the travel distance of the electric automobile 3 from a car navigation device 35. Also, through a charger 2, the information generation device 4 acquires information related to a power residual amount of a secondary battery 31 obtained from the electric automobile 3 before and after traveling. An electric consumption efficiency calculation unit 442 calculates the efficiency of electric consumption by dividing the travel distance by a difference in a power residual amount between before and after traveling.
