## Abstract

A charging and discharging management system according to the present disclosure is a system for, in regard to a vehicle on which a battery capable of being charged and discharged is mounted, charging and discharging the battery, the charging and discharging management system including: an information collection unit configured to collect boarding information indicating an aircraft which a driver of the vehicle plans to board, the vehicle being parked in a parking lot in an airport; a parking period acquisition unit configured to acquire a parking period of the vehicle based on the boarding information pieces collected by the information collection unit; and a determination unit configured to determine a timing at which the battery mounted on the vehicle is charged and discharged based on the parking period acquired by the parking period acquisition unit.

## Claims

### Claim 1

A charging and discharging management system for, in regard to a vehicle on which a battery capable of being charged and discharged is mounted, charging and discharging the battery, the charging and discharging management system comprising:
an information collection unit configured to collect boarding information indicating an aircraft which a driver of the vehicle plans to board, the vehicle being parked in a parking lot in an airport;
a parking period acquisition unit configured to acquire a parking period of the vehicle based on the boarding information pieces collected by the information collection unit; and
a determination unit configured to determine a timing at which the battery mounted on the vehicle is charged and discharged based on the parking period acquired by the parking period acquisition unit.

### Claim 2 (depends on 1)

The charging and discharging management system according to claim 1, wherein when electric power is supplied from the vehicle parked in the parking lot in the airport to equipment in the airport while a plurality of vehicles are parked in the parking lot in the airport, the determination unit selects, in an order of a length of time until the parking period expires, a predetermined number of vehicles from among the plurality of vehicles parked in the parking lot in the airport as a discharging vehicle that discharges the battery and supplies electric power to the equipment in the airport, and determines a timing at which the battery mounted on the selected discharging vehicle is discharged.

### Claim 3 (depends on 2)

The charging and discharging management system according to claim 2, wherein the determination unit determines a predetermined time before a time when the parking period of the discharging vehicle expires to be a timing at which the battery mounted on the discharging vehicle is charged.

### Claim 4 (depends on 3)

The charging and discharging management system according to claim 3, wherein the determination unit stores a remaining amount of the charge of the battery mounted on the discharging vehicle before discharging, and thereby determines an amount of charge to be charged to the battery so that the amount of the charge of the battery returns to the remaining amount of the charge of the battery mounted on the discharging vehicle before discharging.
