Claim 2:
3. The non-contact charging system according to claim 1, wherein
the charging control device comprises:
a charging efficiency calculator that detects an amount of power transmitted by the power-transmitting unit and an amount of power received by the power-receiving unit, and calculates charging efficiency based on the amount of the power transmitted by the power-transmitting unit and the amount of the power received by the power-receiving unit, and
an occupant-presuming unit that presumes, based on a feature of temporal variation in the charging efficiency calculated by the charging efficiency calculator, at least one of:
whether the user of the vehicle gets in or gets off the vehicle, or whether the user is in the cabin space of the vehicle, and
wherein the charging control device variably controls, based on a result of presumption of the occupant-presuming unit, the amount of power that the power-transmitting unit transmits to the power-receiving unit.
