Abstract
A power supply device controller 11a of a power supply device 4a and power supply device controllers of power supply devices 4b, 4c validate a time t for detecting the output time of the validation power with output times ta, tb, tc of the validation power, respectively. Because the time t for detecting the output time of the validation power matches the output time ta of the validation power, the power supply device controller 11a determines that a vehicle 3 is parked at a charging station2a comprising the power supply device 4a.
