Charging time estimation system, charging time estimation device, and charging time estimation method

摘要

PROBLEM TO BE SOLVED: To provide a charge time estimation system, a charge time estimation apparatus, and a charge time estimation method, which enable the presentation of change time even for an electric vehicle including no function of calculating charge time.SOLUTION: A charge apparatus 11 includes a charge control part 22 for recognizing ID information of an electric vehicle 13 and a battery full-charge capacity thereof and detecting a battery residual amount. A server 12 includes a charge information database 33 for storing, in association with the ID information, the battery full-charge capacity of the electric vehicle 13 and charge-related information at the time of charging the electric vehicle, information including a pre-charge residual amount and a post-charge residual amount. Further, based on charge-related information obtained when charging a target vehicle in the past, charge-related information of other vehicles with a similar condition is obtained, and charge time for the target vehicle is prioritized. The apparatus further includes a control computation part 32 for obtaining, when charging the target vehicle at the present time, charge-related information of other vehicles with the condition similar to the present charging, and estimating charge time of the target vehicle on the basis of the priory order of the target vehicle.SELECTED DRAWING: Figure 2
