METHOD AND APPARATUS FOR CHARGE CONTROL OF A PORTABLE TERMINAL HAVING A SOLAR BATTERY

摘要

Provided is an apparatus for controlling charging of a portable terminal equipped with a solar battery that converts solar energy into an electrical energy, the apparatus including a thermistor in which a resistance value changes according to a temperature change; a comparator which outputs a first signal when a temperature surrounding the thermistor is less than a preset reference temperature as determined by the resistance value change of the thermistor according to the temperature change and outputs a second signal when the temperature is at least the preset reference temperature or more; and a charging unit which is activated and receives the electrical energy from the solar battery to charge a battery when the first signal is inputted from the comparator, and is deactivated and blocks the charge of battery in case the second signal is inputted.

主权项

1. An apparatus comprising:
a temperature sensing unit to measure a temperature; a comparator configured to output a signal based at least in part on a determination that the temperature measured by the temperature sensing unit satisfies a specified condition; and a charger operatively coupled with the comparator, the charger configured to pause an operation associated with solar battery-based battery charging, based on the signal output by the comparator.
