CHARGING DEVICE

WIPO Patent Application WO/2018/179809

A1

The charging device 100 according to the present invention is provided with: a rectifier circuit 10 for rectifying AC power output from an AC power supply 50; a DC-DC converter 20 for converting the voltage of DC power output from the rectifier circuit 10; a charging circuit 30 including a positive electrode contact point TP1, which makes contact with the positive electrode terminal of a mounted secondary battery 60, and a first negative electrode contact point TP2 and a second negative electrode contact point TP3, which make contact with the negative electrode terminal of the secondary battery 60, and receiving the output voltage of the DC-DC converter 20 applied between the positive electrode contact point TP1 and the first negative electrode contact point TP2; and a control circuit 40 including a photocoupler PC that turns on according to the potential difference between the positive electrode contact point TP1 and the second negative electrode contact point TP3 and outputting an enable signal for the DC-DC converter 20 when the photocoupler PC turns on.
