Abstract

PURPOSE: To enable forcible recharge of even secondary cell inter resistance of which is increased through over discharge, by detecting terminal voltage of a secondary cell in synchronization with a zero-cross signal fed from a zero- cross signal detecting circuit.
CONSTITUTION: A DC power source 11 is connected in series with a secondary cell 12, a constant current control circuit, i.e. a switching element 13, and a resistor 14. A voltage detecting circuit 15 is connected across the secondary cell 12 and the output therefrom is provided through an A/D converter 16 to a microcomputor 17. An output from a zero-cross signal detection circuit 18 in the DC power source 11 is also provided to a microcomputor 17. The microcomputor 17 detects terminal voltage of the secondary cell 12 in synchronization with a zero-cross signal and controls the switching element 13 through a D/A converter 19 and an operational amplifier 20.
