1. A power supply system comprising:
- movable power-receiving units, each power-receiving unit including at least one power-receiving device receiving electric power from outside of the power-receiving unit and at least one power-supplying device supplying, to outside of the power-receiving unit, at least part of electric power received by the power-receiving device; and
a power-supplying unit supplying electric power to the power-receiving device of one of the power-receiving units;
wherein each power-receiving unit is configured to supply electric power from the power-receiving device to the power-supplying device without supplying electric power from the power-receiving device to an internal consumption when a voltage of electric power to be supplied from the power-receiving device is less than the voltage required to drive or charge the internal consumption.

10. A wireless power supply method comprising:
-
an arrangement step of arranging a power-supplying device of a movable first power-receiving unit and a power-receiving device of a movable second power-receiving unit facing each other; a first power-supplying step of wirelessly supplying electric power to a power-receiving device of the first power-receiving unit from outside of the first power-receiving unit; and a second power-supplying step of wirelessly supplying, to the power-receiving device of the second power-receiving unit from the power-supplying device of the first power-receiving unit, electric power obtained by the power-supplying device of the first power-receiving unit from the power-receiving device of the first power-receiving unit without supplying electric power from the power-receiving device of the first power-receiving unit to an internal consumption when a voltage of electric power to be supplied from the power-receiving device of the first power-receiving unit is less than the voltage required to drive or charge the internal consumption.
