Title:
POWER RECEPTION APPARATUS, POWER TRANSMISSION APPARATUS, AND WIRELESS POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/083223
Kind Code:
A1
Abstract:
The present invention has: a power reception coil that receives power from a power transmission apparatus in a wireless manner; a secondary battery that is charged with the power supplied from the power reception coil; a load resistor; a switch that switchably connects the secondary battery and the load resistor to the power reception coil; and a power reception controller that controls the switch on the basis of a power supply state of the power reception coil from the power transmission apparatus, and a charge state of the secondary battery. The present invention simplifies a wireless power supply system, and reduces the size and power consumption of the power reception apparatus.
