Abstract: A terminal device including a solar battery panel; a panel temperature-detection unit configured to detect a temperature measured near the solar battery panel; a power generation-state determination unit configured to detect an illuminance measured near the solar battery panel; a battery temperature-detection unit configured to detect a temperature measured near a secondary battery charged through power generated through the solar battery panel; a control unit configured to estimate a change in the temperature detected through the battery temperature-detection unit based on the temperature detected through the panel temperature-detection unit and the illuminance obtained through the power generation-state determination unit, and determine a remaining time when the estimated temperature measured near the secondary battery reaches a temperature at which the charging of the secondary battery is stopped; and a notification unit configured to provide notification about the remaining time determined through the control unit.

Abstract: [Object] To achieve both prevention of overcharging of the battery and convenience of the user.
[Solution] An information processing device includes: a charged capacity detection unit configured to detect a charged capacity of a battery; a charging control unit configured to control a charging circuit; and a specification unit configured to specify when discharge of the battery starts. The charging control unit performs charging suppression control on the charging circuit such that the battery is charged to a preparatorily charged capacity that is lower than a fully charged capacity of the battery, on the basis of the charged capacity detected by the charged capacity detection unit, the charging of the battery stops when the charged capacity of the battery reaches the preparatorily charged capacity, and the charging of the battery restarts from the preparatorily charged capacity before discharge of the battery starts.
