CHARGING SYSTEM

A charging system includes a controller, a charging station configured to be able to charge a vehicle, a first vehicle, and a second vehicle. The controller includes a processor and a memory coupled to the processor. The processor is configured to perform a process including: receiving a reservation for charging of the first vehicle at the charging station; deriving an estimated arrival time of the first vehicle at the charging station, based on a current location and a velocity of the first vehicle; and, when the estimated arrival time is later than a reserved start time of the charging of the first vehicle, allowing charging of the second vehicle at the charging station during a part of a period or an entire period from the reserved start time to the estimated arrival time.
