Problems solved by technology

[0006] However, the above-mentioned conventional non-contact charging system has a disadvantage in that the charging efficiency depends on the positional relationship between the primary coil and the secondary coil
That is, in the case where there is a positional deviation between the primary coil and the secondary coil, the induced electromotive force cannot be sufficiently induced in the secondary coil, so the charging efficiency of this non-contact charging system is lower than that of the contact charging system. Low

Abstract

The present invention relates to a contact-less power supply magnetically coupled to a battery device having a receiving coil therein, for contact-less charging the battery device, the contact-less power supply having a sending coil array including a plurality of sending coils for inducing a charging power to the receiving coil; and a driving means for detecting a sending coil magnetically coupled to the receiving coil and selectively driving only the detected sending coil.

Description

technical field [0001] The present invention relates to power supplies for portable electronic devices, and more particularly, to contactless charging systems utilizing inductive coupling. Background technique [0002] Rechargeable secondary batteries are installed in portable electronic devices such as mobile communication terminals, PDAs, and the like. To charge the secondary battery, a separate power source is required to power the battery of the portable electronic device using household commercial power. Typically, the power supply and the battery each have separate external contact terminals whereby the power supply and the battery are electrically connected by connecting the two contact terminals. [0003] However, if the contact terminals protrude outward, the aesthetic appearance will be spoiled, and the contact terminals will be contaminated by external impurities, resulting in poor contact state. Also, the battery is prone to lose charged energy if the user acci...
