1. A system for controlling power consumption of a high voltage battery, the system comprising:
a driver's requested torque determiner configured to determine a driver's intention to accelerate a vehicle and to calculate a driver's requested torque;
an available power amount calculator configured to calculate an available power amount of a difference between an existing power consumption amount of electronic components configured to use the high voltage battery as a power source and a minimum power consumption amount of the electronic components required by a vehicle system, wherein the electronic components are components unrelated to generation of a driving force of the vehicle; and
a driving controller configured to:
variably control power applied to the electronic components and power applied to a drive motor of the vehicle upon determining the driver's intention to accelerate the vehicle; and
distribute a portion of the available power amount to the drive motor so as to improve an acceleration performance of the vehicle when the available power amount is greater than a minimum power amount sufficient to affect the driving force of the vehicle.
