Document Type and Number:
Japanese Patent JP5258521
Kind Code:
B2
Abstract:
Power is contactlessly supplied from power transmitting means (12) to power receiving means (14). A transmitting efficiency detecting means (18) detects the transmitting efficiency between the power transmitting means (12) and the power receiving means (14), and a determining means (20) determines whether the transmitting efficiency detected by the efficiency detecting means (18) is equal to or greater than a specified value. If the transmitted efficiency is less than the specified value, an obstruction may be present so power temporarily stops being transmitted.
