Abstract
The amount of power generated by a solar cell is used for charging more efficiently. An activation determination meansactivates a charging control circuitby allowing a maximum output current from a solar cellto a GND potential to flow and detecting that the output current is equal to or greater than current consumption of the charging control circuitinstead of monitoring an unstable output voltage from the solar cell. Thus, the charging control circuitcan be activated more precisely in comparison to a case where an output voltage is monitored under the condition that the charging control circuitis operated only by the amount of power generated by the solar cell. Thereby, a power instrumentis charged more efficiently with the amount of power generated by the solar cell.
