NON-CONTACT POWER SUPPLY SYSTEM AND CONTROL METHOD FOR NON-CONTACT POWER SUPPLY SYSTEM
First Claim
1. A non-contact power supply system comprising a power supply apparatus, a power receiving apparatus, and a relay apparatus, whereinfirst transmission efficiency which is transmission efficiency of supply power in the case of supplying power in a first power supply mode of directly supplying the power from the power supply apparatus to the power receiving apparatus and also supplying the power from the power supply apparatus to the power receiving apparatus through the relay apparatus, andsecond transmission efficiency which is transmission efficiency of supply power in the case of supplying the power in a second power supply mode of directly supplying the power from the power supply apparatus to the power receiving apparatus and not supplying the power from the power supply apparatus to the power receiving apparatus through the relay apparatusare compared,the power is supplied from the power supply apparatus to the power receiving apparatus in the second power supply mode in the case that the second transmission efficiency is higher than the first transmission efficiency, andthe power is supplied from the power supply apparatus to the power receiving apparatus in the first power supply mode in the case that the second transmission efficiency is equal to or lower than the first transmission efficiency.
