1. A power supply system, comprising:
a plurality of electric motors including a plurality of power transmitters, respectively, the plurality of power transmitters being configured to transmit a power via a contactless power supply method;
a plurality of load devices including a plurality of power receivers, respectively, the plurality of power receivers being configured to receive the power transmitted from the plurality of power transmitters; and
a controller configured to control a power supplied to the plurality of power transmitters and/or a direction of power transmission from the plurality of power transmitters,
wherein the plurality of load devices further include a plurality of wireless communication units, respectively, the plurality of wireless communication units being configured to respectively transmit, to the controller, power reception information of the plurality of load devices, the power reception information relating to a power reception state of whether the power transmitted from the plurality of power transmitters to the plurality of power receivers included in the plurality of load devices satisfies a power required to operate each load device of the plurality of load devices,
wherein the controller controls the power supplied to the plurality of power transmitters and/or the direction of power transmission from the plurality of power transmitters on a basis of the power reception information of the plurality of load devices, and
wherein the controller controls the power supplied to the plurality of the power transmitters and/or the direction of power transmission from the plurality of power transmitters such that the power required to operate each load device of the plurality of load devices is respectively received by each load device of the plurality of load devices and a total value of the power supplied to the plurality of power transmitters of all of the plurality of electric motors is minimized.
