POWER CONTROL METHOD AND POWER CONTROL APPARATUS FOR A VEHICLE

A method for controlling power of a vehicle includes: collecting, by a controller, data on a current consumed by an electrical load of the vehicle and calculating an average current consumption for the electrical load based on the collected data on the current consumed; determining, by the controller, power conversion of a converter to generate a converted current having an amount corresponding to the calculated average current consumption; variably controlling, by the controller, the power conversion of the converter to compensate for a deterioration state of a battery when the deterioration state of the battery provided to supply power to the electrical load occurs; and securing, by the controller, higher power conversion efficiency of the converter by controlling power supply to the electrical load when the deterioration state of the battery does not occur.
