Method and apparatus for providing charging information regarding portable terminal with solar cell
First Claim
1. A method for providing charging information in a portable terminal with a solar cell, comprising:
- receiving at least one of location information, time information regarding a portable terminal and environmental information containing at least one of the temperature, humidity, seasons and weather conditions;
outputting charging information corresponding to the at least one of the received location information, time information and the environmental information,wherein the charging information comprises at least one of an optimal charging angle wherein the solar cell performs a charging process with a highest charging efficiency, or an average charging efficiency at the optimal charging angle;
monitoring the optimal charging angle by comparing a tilt angle output from a tilt sensor, with the optimal charging angle; and
outputting, if a difference between the tilt angle and the optimal charging angle is outside a preset range, a voice signal or an alert message indicating that the tilt angle of the portable terminal should be corrected.

Abstract
A method and apparatus provides charging information regarding devices such as a portable terminal with a solar cell. The solar cell charges the battery of the portable terminal with the highest charging efficiency at an optimal charging angle. The optimal charging angle is determined according to the location information regarding the portable terminal and time information. When the solar cell performs a charging process with the highest charging efficiency, the portable terminal provides a user with an average charging efficiency and the help containing a user'"'"'s manual of the solar cell. The average charging efficiency is determined according to environmental conditions, such as temperature, humidity, weather conditions, etc.
