PURPOSE: A system for controlling an electronic devices of an electric vehicle is provided to increase the stability of the system by integrating a wire harness, a fuse box, an ETACS(Electronic Time Alarm Control system), and a 12V-auxiliary battery on one unit. CONSTITUTION: A power transforming unit(110) converts high voltage power outputted from a main battery into low voltage power. A control unit(120) unifies the high voltage power outputted from the main battery and power of the power transforming unit(110). The control unit(120) performs a control operation so as to supply low voltage to a low voltage power driving system of the electric vehicle through the power transforming unit(110). The power transforming unit(110) includes a DC(Direct Current)-to-DC converter for making 12V-power and connecting power to a high voltage power driving system of the electric vehicle to supply high voltage to the control unit(120).
