A bidirectional on-board charger (BOBC) may be disposed between an electric vehicle supply equipment (EVSE) and a battery equipped in an electric vehicle to convert power while performing charging/discharging in two-way direction, supply a converted DC power to the battery to driving the electric vehicle, convert a power of the battery into an AC power in converting power with respect to the EVSE, and supply the AC power to a grid or a load. In a method and apparatus of controlling a BOBC, an operation mode of the BOBC proceeds to an optimum point by comparing battery voltage values in a charging mode and proceeds to an optimum point on the basis of an accurate battery state value through a grid connection in a discharging mode.
