The present invention relates to a power control system and a method for a mild hybrid vehicle, and more specifically, to a power control system for a mild hybrid vehicle including a converter for converting power of a high voltage power supply unit into a direct current to maintain a target voltage. The power control system can include: a system efficiency map for storing a system optimum efficiency value which is a product of the efficiency of the converter and the charging efficiency of a low voltage battery; and a hybrid control unit which sets the target voltage, extracts a system optimum efficiency value corresponding to the target voltage from the system efficiency map, and controls the current of the converter.
