1. A power feeding station for feeding power to a receiver comprising a receiver coil comprised in an electric mobility vehicle, the power feeding station comprising:
a feeder configured to feed power to the electric mobility vehicle through the receiver coil; and
a housing defining a predetermined parking position of the electric mobility vehicle and accommodating the feeder, wherein
the feeder comprises
a feeder coil configured to feed power to the receiver through the receiver coil,
a power supply circuit configured to supply alternating current power to the feeder coil, and
a control circuit configured to control a frequency and a voltage of the alternating current power supplied to the feeder coil, and
the control circuit:
determines whether a first parking position of the electric mobility vehicle relative to the housing is to be changed based on a detected value of the frequency of the alternating current power supplied to the feeder coil that allows the receiver to perform a constant voltage output operation, and
based on the detected frequency, provides, through a notification source comprised in the power feeding station or in the electric mobility vehicle, a notification of guidance about a stop position of the electric mobility vehicle relative to the housing to increase power transmission efficiency from the feeder to the receiver in accordance with the detected frequency of the alternating current power with which the receiver outputs a constant voltage or in accordance with the voltage of the alternating current power with which the receiver outputs a constant and predetermined voltage.
