1. A charging management system for applying a first charging device which charges an electric vehicle for rental, and a second charging device which charges the electric vehicle in a shorter necessary time than the first charging device, comprising:

  • a management module configured to manage(a) a rental time slot as a time slot in which a rental reservation of the electric vehicle has been made,(b) a charging time slot in which the second charging device is usable and charging to the electric vehicle by the second charging device is performed for enabling rental of the electric vehicle in the rental time slot,(c) a charging time slot in which the second charging device is not usable and charging to the electric vehicle by the first charging device for enabling the rental of the electric vehicle is performed in the rental time slot, and(d) information indicating a transition of a stored power amount of the electric vehicle, due to the rental of the electric vehicle and the charging to the electric vehicle;

    a display module configured to cause a display device to display(e) a charging time slot on an assumption that the charging to the electric vehicle is performed by the second charging device in a time slot in which the second charging device is usable,(f) a charging time slot of charging to the electric vehicle by the first charging device in a time slot in which the second charging device is not usable, and(g) a time slot which is settable as a new desired rental time slot of the electric vehicle, based on the rental time slots managed by the management module;

    an input module configured to accept an input of a desired rental time slot of the electric vehicle, in the time slots displayed by the display module;

    a first estimation module configured to estimate a power amount which is necessary for renting the electric vehicle with respect to the desired rental time slot input by the input module;

    a second estimation module configured to estimate, based on the power amount estimated by the first estimation module, a time slot in which charging by the first and second charging devices is necessary as charging for enabling the rental of the electric vehicle in the input desired rental time slot; and

    a scheduling module configured to set, based on the information managed by the management module, the input desired rental time slot as a time slot in which the electric vehicle is rentable, if the charging for enabling the rental of the electric vehicle in the input desired rental time slot and the rental time slot in which the rental reservation has been made is possible in the time slot estimated by the second estimation module.
