CABLE INSTALLMENT TYPE CHARGING CONTROL DEVICE AND METHOD OF OPERATING THE SAME
First Claim
1. A cable installment type charging control device for charging an electric vehicle (EV) by using power of a grid-side, the cable installment type charging control device comprising:
- a first relay delivering power of the grid-side to an EV-side;
a second relay delivering power of the grid-side to the EV-side; and
a first sub fusion detecting unit comprising a third relay, a first resistor, and a first photo coupler which are connected to each other in series, the first sub fusion detecting unit detecting whether the first relay is fused through an-EV side terminal of the first relay and a grid-side terminal of the second relay.
