Document Type and Number:

WIPO Patent Application WO/2014/087823

Kind Code:

A1

Abstract:

A non-contact power supply apparatus (201) is provided with a power receiving coil (22), and transmits and receives power in a non-contact manner by means of magnetic coupling between the power receiving coil and a power transmitting coil (12) of a ground-side unit (100) that is provided on the ground. The non-contact power supply apparatus is provided with: a remaining quantity detecting unit (25a), which detects a remaining quantity of a battery (28) that is provided in a vehicle parked in a parking space that is provided with the power transmitting coil; a charge start determining unit (25b), which determines whether to start charging operations with respect to the battery or not on the basis of whether the battery remaining quantity detected by means of the remaining quantity detecting unit is equal to or less than a charge start threshold value; and a charge control unit (25c), which starts the charging operations in the cases where the charge start determining unit determined to start the charging operations.
