VEHICLE CHARGING DEVICE AND METHOD
First Claim
1. A vehicle charging device comprising:
- a grid plug connected to an external power source for providing power for vehicle charging;
a grid cable connected to the grid plug;
a charging circuit interrupt device (CCID) connected to the grid cable and comprising a relay circuit for a vehicle charging control;
a coupler connected to the vehicle; and
a coupler cable connecting the coupler and the CCID,wherein the grid plug comprises first and second terminals electrically connected to the external power source and first and second temperature sensors disposed at positions separated by a predetermined distance from the first and second terminals, and the first and second temperature sensors are commonly connected to a ground line earthed.

12. A vehicle charging method for controlling charging by using a device comprising a plug connected to a power supply source providing power necessary for vehicle charging and a CCID connected to the plug through a charging cable, the method comprising:
-
reading, by the CCID, temperature values measured by two temperature sensors provided in the plug and determining a greater one of the read measurement temperature values as a current temperature when the vehicle charging is performed by using the plug and charging cable, wherein the two temperature sensors disposed at positions separated by a predetermined distance from terminals electrically connected to the power supply source are provided in the plug; determining whether a difference between the temperature values measured by the temperature sensors is greater than a first set temperature; and stopping the vehicle charging when the difference between the temperature values measured by the temperature sensors is greater than the first set temperature. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
