Power reception device and power reception method for non-contact power transmission

A power reception control device includable in a non-contact power transmission system that performs non-contact power transmission from a power transmission device to a power reception device through a primary coil and a secondary coil, the power reception device supplying power to a first load, the power reception control device comprising:

• a power reception section that converts an induced voltage in the secondary coil into a direct-current voltage;
• a load modulation section that modulates a second load of the power reception section;
• and
• a power-reception-side control section that controls an operation of the power reception device,
• the first load including a charge control device that controls power supplied to a battery,
• the load modulation section being configured to transmit information from the power reception device to the power transmission device through the secondary coil and the primary coil utilizing load modulation of the second load, and
• the power-reception-side control section being configured to reduce the power supplied to the battery by controlling a charge operation of the charge control device when the power-reception-side control section controls the load modulation section to transmit the information from the power reception device to the power transmission device.
