Abstract:
A feed unit includes: a power transmission section configured to perform power transmission using a magnetic field or an electric field, to a device to be fed including a secondary battery; and a power-transmission control section configured to control power transmission operation in the power transmission section. In a charging period in which charging to the secondary battery is performed based on transmitted power in the power transmission, when the device to be fed including the secondary battery is activated, the power-transmission control section controls the power transmission operation, to increase the transmitted power.
