Non-Contact Power Supply Apparatus, Non-Contact Power Supply System, and Non-Contact Power Supply Method

摘要

A non-contact power supply apparatus includes a power receiving coil and transmits and receives power in a non-contact manner through magnetic coupling between the power receiving coil and a power transmitting coil included in a ground-side unit. The non-contact power supply apparatus includes: a remaining power detecting part configured to detect the remaining power of a battery; a charge start determining part configured to determine whether or not to start a charge operation of the battery, based on whether or not the remaining power of the battery detected by the remaining power detecting part is equal to or less than a charge start threshold; and a charge controlling part configured to start the charge operation if the charge start determining part determines that the charge operation is to be started.

1. A non-contact power supply apparatus including a power receiving coil and configured to transmit and receive power in a non-contact manner through magnetic coupling between the power receiving coil and a power transmitting coil included in a ground-side unit provided on a ground, comprising:
a remaining power detector configured to detect remaining power of a battery included in a vehicle to be parked in a parking space in which the power transmitting coil is provided; a charge start determining circuit configured to determine whether or not to start a charge operation of the battery, based on whether or not the remaining power of the battery detected by the remaining power detector is equal to or less than a charge start threshold; and a charge controller configured to start the charge operation if the charge start determining circuit determines that the charge operation is to be started, wherein the charge start determining circuit changes the charge start threshold in accordance with a condition of use of the battery during travel of the vehicle before parking.
