NON-CONTACT POWER SUPPLY METHOD AND NON-CONTACT POWER SUPPLY SYSTEM
First Claim
1. A non-contact power supply method that enables charging electricity to a vehicle by electromagnetically coupling a power receiving coil mounted in the vehicle to a power supply coil of a power supply device which is placed to an outside of the vehicle, the non-contact power supply method comprising:
- a checking step of checking to see that an electronic appliance remains left inside the vehicle, based on wireless communication information emitted by the electronic appliance left inside the vehicle; and
when having detected that the electronic appliance remains left, a current control step of controlling a current value of power supply according to an allowable current value of the detected electronic appliance.

Abstract
It is intended to provide a safe non-contact charging environment that enables finding an electronic appliance that remains left in a vehicle before start of charging and preventing trouble that an electronic appliance breaks down by electromagnetic waves generated during charging by means of electromagnetic coupling. A process of checking to see that an electronic appliance remains left inside a vehicle, based on wireless communication information emitted by the electronic appliance left inside the vehicle is performed in advance. When it has been detected that an electronic appliance remains left, a charging current value is controlled according to an allowable current of the detected electronic appliance or an alert is generated to notify that the electronic appliance remains left.
