Power control method and power control apparatus for a vehicle

A power control apparatus for a vehicle, the apparatus comprising:

• a converter configured to supply power to an electrical load and a battery;
• and
• a controller configured to
• control power supply to the electrical load and the battery by controlling the converter,
• collect data on a current consumed by the electrical load of the vehicle,
• calculate an average current consumption for the electrical load based on the collected data on the current consumed,
• determine power conversion of the converter to generate a converted current having an amount corresponding to the calculated average current consumption,
• variably control the power conversion of the converter to compensate for a deterioration state of the battery when the deterioration state of the battery provided to supply power to the electrical load occurs, and
• secure 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.

A method for controlling power of a vehicle, the method comprising:

• 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 multi-phase direct current-direct current (DC-DC) converter to generate a converted current having an amount corresponding to the calculated average current consumption;
• controlling, by the controller, the number of phase activations of the multi-phase DC-DC converter to increase so as 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 multi-phase DC-DC converter by controlling power supply to be selectively restricted to the electrical load when the deterioration state of the battery does not occur.
