  • Publication number: 20180236892
    Abstract: A system and method for controlling charging of plug-in vehicle are provided to charge a high-voltage battery mounted in the vehicle by converting AC power into DC power using an OBC. The method includes determining whether the high-voltage battery is charged by the operation of the OBC and whether the temperature of the high-voltage battery is greater than a predetermined reference cooling temperature while the high-voltage battery is charged to determine whether to cool the high-voltage battery. Additionally, whether the temperature of the high-voltage battery is greater than a predetermined failure determination temperature is determined to determine whether the high-voltage battery is abnormal when the temperature of the high-voltage battery is greater than the reference cooling temperature. A battery cooling fan mounted in the vehicle is maximally driven to cool the high-voltage battery when the temperature of the high-voltage battery is greater than the failure determination temperature.
