Abstract

PURPOSE: To enable using a charged body even during a charge and charging a secondary battery efficiently without deteriorating said secondary battery by detecting the charging capacity of said secondary battery through the detection circuit of said charged body to keep a charging current constant and by controlling a supply voltage from a charging body, even if no charging capacity can be detected.
CONSTITUTION: Voltage is supplied from a constant voltage circuit 10 to voltage supply lines 19, 21. The voltage on the voltage supply line 19 charges a secondary battery 6 and the voltage on the voltage supply line 21 is supplied to an internal circuit 9. Said internal circuit 9 is supplied with a supply voltage by a charging body 11 to operate a charged body 12 while charging the secondary battery 6. A detection circuit 18 detects the charging capacity of said secondary battery 6 to output a voltage indicated value to a control circuit 15, which transmits said voltage indicated value to a voltage control circuit 14, which controls the constant voltage circuit 10 to keep a current constant.
