Abstract: A server includes a communication device and a processor. The communication device obtains a power rate unit price dependent on a region where external charging is performed and a time slot when external charging is performed. The processor calculates a first power rate indicating a power rate when the external charging is performed with a first power feeding facility provided at a departure place before departure of a vehicle, calculates a second power rate indicating a power rate when the external charging is performed with a second power feeding facility provided in the vicinity of a traveling route after departure of the vehicle, and when the second power rate is lower than the first power rate, reduces an amount of power feeding during the external charging with the first power feeding facility, as compared with when the second power rate is equal to or higher than the first power rate.

Abstract: A running mode proposal device for proposing a running mode up to a destination of a vehicle is configured to: select a first running route by a predetermined algorithm unrelated to noncontact power supply; project, when assuming the vehicle runs on a predetermined running route, a value of a parameter relating to an electric energy projected as being supplied at a power supply section on the running route to the vehicle; select a second running route by which a projected supplied electric energy will be greater than a predetermined standard electric energy if the projected value of the parameter when assuming the vehicle runs on the first running route is a value indicating the projected supplied electric energy is less than the standard electric energy; and propose, as the running route, the first running route, and, when the second running route is selected, further proposing a second running route.

Abstract: The power supply system includes a plurality of power supply apparatuses configured to transmit power to vehicles by non-contact. The plurality of power supply apparatuses includes a first power supply apparatus 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 a second power supply apparatus installed in a second region different from the first region. An amount of power supplied from the first power supply apparatus to a vehicle is made greater than an amount of power supplied from the second power supply apparatus to a vehicle.
