Abstract: The charging/discharging time of electric vehicle is shortened. The charging/discharging management system includes: a first acquisition controller configured to acquire vehicle information including vehicle capabilities regarding charging/discharging capabilities of multiple electric vehicles; a second acquisition controller configured to acquire device information including device capabilities regarding charging/discharging capabilities of multiple charging/discharging devices capable of charging/discharging the electric vehicles; and an assigning controller configured to compare the vehicle capabilities and assign the charging/discharging device having a high device capability among the charging/discharging devices for which device information has been acquired in the second acquisition controller, to the electric vehicle having a high vehicle capability.

Abstract: A service system includes a reservation section by which a reservation for a commodity or a service in a commercial facility can be made and specific information for an electric vehicle that visits the commercial facility can be set, a connection confirmation section that detects that an electric vehicle corresponding to the specific information set by the reservation section has been connected to a charge and discharge device of the commercial facility, and a notification section that notifies the commercial facility that connection of the electric vehicle corresponding to the specific information to the charge and discharge device has been detected by the connection confirmation section.

Abstract: Use of a charge-and-discharge spot can be promoted. A charge-and-discharge management system includes a setting controller that sets an incentive linked with a charge-and-discharge spot for each charge-and-discharge spot and a presentation controller that presents the incentive set for each charge-and-discharge spot to a user using an electric vehicle. The charge-and-discharge management system may further include an acquisition controller that connects the electric vehicle to a charge-and-discharge device installed in the charge-and-discharge spot and acquires connection spot information that is information of the charge-and-discharge spot that is a connection destination when charging and discharging is started, and a providing controller that provides an incentive set for the charge-and-discharge spot included in the connection spot information acquired by the acquisition controller when the charging and discharging of the electric vehicle is completed.
