Abstract

Disclosed is a charging apparatus for charging a secondary battery incorporated in a portable electronic device. The charging apparatus includes: a contactless IC card reader configured to supply operating power to a contactless IC card unit incorporated in the portable electronic device and have an authentication function of authenticating that an object to be authenticated is a correct one; a charging circuit configured to perform contactless charging of the secondary battery; and a control unit configured to activate the charging circuit if an authentication result is OK after the contactless IC card reader authenticates an object to be authenticated when the object to be authenticated is placed.

Description

[0001] Cross References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application JP 2005-284500 filed in the Japan Patent Office on Sep. 29, 2005, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a charging device and a charging system for portable electronic devices. Background technique [0004] Portable electronic devices such as cellular phones obtain their operating power from secondary batteries, and need to be charged periodically. [0005] In current cellular phones, contact charging is mainly performed in which an AC adapter is directly connected to a connector of the cellular phone, or an exposed electrode of the phone is brought into contact with a terminal portion provided on a charging stand. In contact charging, a phenomenon with a charging failure occurs due to contamination of a metal portion as an electrical contact or poor ...
