  • Patent number: 11135926
    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.

  • Patent number: 11091051
    Abstract: A cooling control system and method for an on-board charger of a plug-in vehicle drive an electric water pump using a cooling control map when the temperature of the on-board charger equipped in a plug-in vehicle is equal to or above an overheat prevention temperature. The cooling control system and the method determine an entry of an optimal cooling control mode to cool the on-board charger to a temperature at which charging operational efficiency is maximized when the temperature of the on-board charger is below the overheat prevention temperature. Thereby, the on-board charger is cooled and the standard charging efficiency and the charge depletion fuel economy of the plug-in vehicle is maximized.
