APPARATUS AND METHOD FOR CONTROLLING CHARGING A HIGH VOLTAGE POWER GRID STRUCTURE OF A VEHICLE

A method for controlling charging of a high voltage power grid structure of a vehicle is provided. The method includes measuring battery voltage of a vehicle and transmitting the measured voltage to a first charger. Output voltage of the first charger is matched with the transmitted voltage and provided to a charging controller via communication between the charging controller and the first charging port to which the first charger is coupled. The vehicle is then charged by connecting a high-voltage relay to be connected to a first charging port to which the first charger is coupled. The process is repeated while the vehicle is being charged between the charging controller and a second charger by connecting to a second charging port to which a second charger is coupled.
