Disclosed is a power supply device of an electric field load of an electric vehicle capable of automatically selecting power supply sources which are supplied to the electric field load according to a charging mode and a driving mode using commercial power by separating power supply line. The power supply device of the electric field load of the electric vehicle comprises a high-voltage charger, a high-voltage battery, a first switch, a second switch, and a controller. The high-voltage charger outputs high-voltage DC power by converting the commercial power through DC/DC conversion. The high-voltage battery stores driving power. The first switch comprises an LDC such as a low-voltage DC/DC converter. One side of the first switch is connected between power converting sections of the high-voltage charger. The other side of the first switch is connected to an input end of the LDC. The second switch is connected between the high-voltage battery and the LDC. The controller controls on/off of the first switch and the second switch according to the charging mode and the driving mode of the electric vehicle.
