Title: (EN) APPARATUS FOR CHARGING PORTABLE DEVICES USING SOLAR CELL
Abstract: front page image
(EN)

Provided is an apparatus for charging a variety of portable devices using external light without an additional power, and more particularly, an apparatus adding a voltage pump function in which a full charge or quick charge is performed by artificial-intellectually recognizing types of portable devices, the state of a residual current of a battery inside the portable devices is sensed, a voltage of the apparatus is boosted and the battery is fully charged. The apparatus includes a microcomputer, a built-in battery charging the power generated in the solar cell, a built-in battery charging pulse width modulation (PWM) unit switching a charging operation into the built-in battery from the solar cell and controlling the size of a voltage (a charge voltage) supplied to the built-in battery, a built-in battery discharging PWM unit controlling (switching) a discharging operation in which the voltage charged in the built-in battery is discharged into the external device and controlling the size of a discharge voltage, a temperature sensor sensing a temperature of the built-in battery, and a voltage input/output unit outputting the voltage discharged from the built-in battery to the external device and having a common connection terminal to which voltage is inputted from the outside, so as to supply an output voltage of an external battery charger to the built-in battery.
