摘要： 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.
