Document Type and Number:
WIPO Patent Application WO/2014/076801
Kind Code:
A1
Abstract:
[Problem] To make it possible to efficiently supply power in a non-contact manner from a power supply side to a power receiving side. [Solution] A non-contact power supply system (1) in which a first transmission efficiency that is the transmission efficiency of supplied power when power is supplied using a first power supply mode in which power is supplied directly from a power supply device (10) to a power receiving device (20) and power is supplied from the power supply device (10) to the power receiving device (20) via a relay device (30) is compared with a second transmission efficiency that is the transmission efficiency of supplied power when power is supplied using a second power supply mode in which power is supplied directly from the power supply device (10) to the power receiving device (20) but power is not supplied from the power supply device (10) to the power receiving device (20) via the relay device (30). When the second transmission efficiency is higher than the first transmission efficiency, power is supplied from the power supply device (10) to the power receiving device (20) using the second power supply mode. When the second transmission efficiency is equal to or lower than the first transmission efficiency, power is supplied from the power supply device (10) to the power receiving device (20) using the first power supply mode.
