Abstract
To provide a power supply system, a power device, and a power method capable of wireless power supply with a simple configuration. A power supply system includes a first infrared output unit provided on a first object, the first infrared output unit having a first directivity configured to output a first infrared ray in a first direction in which a second object that relatively moves with respect to the first object is situated, the first infrared output unit being configured to output the first infrared ray, a reflector provided on the second object, the reflector being configured to reflect the first infrared ray by retroreflection, a second infrared output unit provided on the second object, the second infrared output unit having a second directivity configured to output a second infrared ray in a second direction in which the first object that relatively moves is situated, the second infrared output unit being configured to output the second infrared ray by using power received by wireless power supply, and a power supply provided on the first object, the power supply being configured to, in a case of receiving a reflected infrared ray of the first infrared ray reflected by the reflector or in a case of receiving the second infrared ray, output a beam in an arrival direction of the reflected infrared ray or the second infrared ray.
