NON CONTACT CHARGE SYSTEM, CONTROL METHOD OF THE NON CONTACT CHARGE SYSTEM, PORTABLE ELECTRONIC APPARATUS, AND CHARGER

摘要

PROBLEM TO BE SOLVED: To charge an apparatus with a proper charge amount even though the apparatus is placed in a position where normal charge is not conducted.

SOLUTION: A non contact charge system includes: a charger 100 transmitting electric power in a non contact manner; and a portable phone 1 having a secondary battery receiving the electric power transmitted from the charger 100 in a non contact manner and conducting charging. In the non contact charge system, the portable phone 1 has: multiple power reception parts 10 (1), (2) receiving the electric power transmitted from the charger 100; a charge state monitoring part 21 monitoring the charge state of the secondary battery; and a portable phone side communication part 14 conducting communication with the charger 100. The charger 100 has: multiple power transmission parts 110 (1) to (12) transmitting the electric power to the portable phone 1; a charger side communication part 140 communicating with the portable phone 1; and a power transmission control part 121 controlling power transmission of the power transmission parts 110 based on the monitoring result of the charge state monitoring part 21.
