The present invention provides a high voltage system of an electric vehicle. More particularly, it relates to a high voltage system of an electric system which makes it possible to remove a sub-battery conventionally required in such systems by allowing a high voltage battery to function as the sub-battery. The high voltage system includes a high voltage battery, in which a cell and/or a module of the high voltage battery is connected to low voltage electric equipment through an NC relay, such that power of the cell and/or the module of the high voltage battery is supplied to the low voltage electric equipment at ignition-off.
