1. A system for controlling charging of a battery of a vehicle, the system comprising:
an on-board charger (OBC) mounted in the vehicle, setting a required charging current based on available charging current information received from a power supply unit supplying power for charging the battery, transmitting the required charging current to the power supply unit, and converting the power supplied from the power supply unit to charge the battery, wherein the power supply unit is installed outside of the vehicle;
a controller determining whether charging of the battery is completed, and when it is determined that charging of the battery is abnormally terminated in a state where charging is not completed, changing the required charging current to charge the battery based on first information for charging current supplied from the power supply unit upon abnormal termination of charging and second information for charging current supplied from the power supply unit upon normal completion of charging, and
a storage unit storing the first information and the second information;
wherein the first information is supplied from the power supply unit upon abnormal termination of charging the battery in decreasing order;
wherein the second information is supplied“from the” power supply unit upon normal completion of charming the battery in decreasing order; and
wherein, when it is determined that charging of the battery is abnormally terminated, the controller compares an abnormal charging current, which is supplied from the power supply unit upon abnormal termination of charging, with a first normal charging current having a maximum intensity among the second information stored in the storage unit, and when the abnormal charging; current is greater than the first normal charging current, the controller changes the required charging current to the first normal charging current to allow the battery to be charged.
