Abstract:
1. A method, implemented on a terminal device having a solar battery panel and a secondary battery that is charged through power generated through the solar battery panel, comprising: detecting a temperature measured adjacent to the solar battery panel; detecting an illuminance measured adjacent to the solar battery panel; detecting a temperature measured adjacent to the secondary battery; estimating a change in the temperature measured adjacent to the secondary battery based on the temperature measured adjacent to the solar battery panel and the illuminance measured adjacent to the solar battery panel, and determining a remaining time until the estimated temperature measured adjacent to the secondary battery reaches a temperature at which the charging of the secondary battery is stopped by comparing the temperature measured adjacent to the solar battery panel and the illuminance measured adjacent to the solar battery panel with predetermined stored data values; and providing a notification about the remaining time.
