CHARGER FOR ELECTRIC VEHICLE
First Claim
1. A charger to supply current from a commercial power source to a battery of an electric vehicle, the charger comprising:
- a connector connected to the electric vehicle;
a plug connected to an outlet of the commercial power source to supply the current for charging the battery of the electric vehicle;
a switching unit to selectively shut off the current supplied from the commercial power source to the electric vehicle according to a temperature of the charger;
a display unit to display information about an operation of the charger; and
a control unit to control the operation of the charger,wherein the control unit controls the display unit to display two kinds of mutually different information when the current supplied from the commercial power source to the electric vehicle is shut off because the battery is fully charged or the connector is separated from the electric vehicle and when the current supplied from the commercial power source to the electric vehicle is shut off by the switching unit.
