Abstract
A method and system for controlling high voltage power of an electric vehicle to efficiently control outputs of power control object parts by controlling low-level controllers provided in the power control object parts through a high-level controller having various types of vehicle information, may include a power state monitoring step in which a high-level controller detects power variations in power control object parts through low-level controllers provided in the power control object parts, a power state determination step in which the high-level controller determines a stable power supply state and an unstable power supply state for the power control object parts on the basis of a preset power reference value, and a load output control step in which the high-level controller controls all load outputs for the power control object parts according to the stable power supply state and the unstable power supply state.
