Power supply system, power supply apparatus, and power supply method

A power supply apparatus configured to:

• transmit power to a hybrid vehicle by non-contact, wherein the power supply apparatus is installed in a predetermined region on a road directly connected to an exit of an area in which operation of internal combustion engines is prohibited or restricted, and
• increase an amount of power supply per unit time to the hybrid vehicle when an amount of traffic of vehicles in the predetermined region is equal to or greater than a predetermined threshold value, compared to when the amount of traffic is less than the threshold value.

A power supply method using a plurality of power supply apparatuses configured to transmit power to a hybrid vehicle by non-contact, wherein the method comprises:

• supplying a first power per unit time from a first power supply apparatus of the plurality of power supply apparatuses installed in a first region positioned on a road directly connected to an exit of an area in which operation of internal combustion engines is prohibited or restricted and where an amount of traffic of vehicles at least temporarily becomes equal to or greater than a predetermined threshold value;
• and
• supplying a second power per unit time from a second power supply apparatus of the plurality of power supply apparatuses installed in a second region different from the first region, wherein an amount of the first power per unit time is greater than an amount of the second power per unit time.
