  • Method and apparatus for charge control of a portable terminal having a solar battery
    Patent number: 9276432
    Abstract: 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.
