Abstract
A method of controlling an electric power supply system for a mild hybrid electric vehicle includes: a step of executing a sequence for turning on the electric power supply system, wherein when an ignition key is turned on, a voltage of the low voltage battery is boosted and in which, when the voltage of the high voltage power network reaches a preset setting voltage, the high voltage relay is closed; a step of causing the vehicle to travel in a normal mode; a step of limiting entering of a failure mode and checking a connected state of the high voltage relay when a voltage drop occurs; and a step of performing again the sequence, when the high voltage relay is opened, and of resuming the traveling of the vehicle in the normal mode when the high voltage relay keeps closed.
