1. An external power feeder connectable to a plurality of power supply source mobile bodies serving as power supply sources, the external power feeder comprising:
a plurality of connection ports which are respectively in connection with the plurality of power supply source mobile bodies;
a connection state acquisition unit that acquires a connection state of each of the plurality of connection ports with the power supply source mobile body;
a power supply state acquisition unit that acquires a power supply state from each of the plurality of power supply source mobile bodies; and
a switching unit that, in a case in which the connection state acquisition unit has detected at least two connections of the power supply source mobile bodies, switches from power supply from one power supply source mobile body that supplies power to power supply from one other power supply source mobile body, among the connected power supply source mobile bodies, based on a power supply state of the one power supply source mobile body acquired by the power supply state acquisition unit,
wherein the connection state acquisition unit acquires a distance from a location of the external power feeder to a charging infrastructure, and calculates a predetermined amount of a power remaining amount required for the power supply source mobile body supplying power to the external power feeder to move to the charging infrastructure, and
the switching unit switches to power supply from the one other power supply source mobile body based on the power supply state of the one power supply source mobile body acquired by the power supply state acquisition unit and the predetermined amount.
