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, wherein the switching unit including a first switching unit which is turned on or off when a charging operation for the battery is started or completed, and a second switching unit which is turned on when the temperature of the charger is less than a predetermined safety temperature and turned off when the temperature of the charger is equal to or higher than the predetermine safety temperature;
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 turns off the first switching unit when information about completion of the charging operation for the battery is transmitted thereto from the electric vehicle.

Abstract
Disclosed is a charger for an electric vehicle. The charger includes a connector connected to the electric vehicle, a plug connected to an outlet of the commercial power source, a switching unit to selectively shut off the current 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 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. The charger is prevented from being damaged due to overheat during the charging operation for the electric vehicle.

5. 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 temperature sensor to sense a temperature of the charger; a first switching unit to selectively shut off the current supplied from the commercial power source to the electric vehicle and to adjust intensity of the current supplied from the commercial power source to the electric vehicle; a control unit to control an operation of the charger; and a display unit to display information about the operation of the charger, wherein the control unit controls the first switching unit to allow a predetermined first current to be applied from the commercial power source to the electric vehicle when the temperature of the charger sensed by the temperature sensor is less than a predetermined first safety temperature and controls the first switching unit to allow a predetermined second current to be applied from the commercial power source to the electric vehicle when the temperature of the charger sensed by the temperature sensor is equal to or higher than the predetermined first safety temperature and less than a predetermined second safety temperature, and the display unit displays two kinds of mutually different information when the current is supplied from the commercial power source to the electric vehicle and when the current supplied from the commercial power source to the electric vehicle is shut off. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
