Contactless power supply system for charging rechargeable battery of portable terminal, has power supply control and/or monitoring unit selecting power supply pattern, and power supply control unit supplying power into selected pattern

摘要

The system has a memory unit (14) storing a table that contains a relationship of a set of power supply pattern corresponding to position and orientation of a power receiving coil (L3) in a power receiver (30) on a power supply surface. A power supply control and/or monitoring unit selects the pattern, which comprises high power supply efficiency according to the position and orientation of the coil, where the position and orientation are estimated by a position-orientation estimation unit based on the table. A power supply control unit supplies power into the selected pattern.
