The invention relates to an integrated power assembly system for an electric automobile. The integrated power assembly system for the electric automobile is characterized in that a motor controller, a charging machine and a DC-DC module are integrated in the same box body and share the same heat dissipation device. The motor controller and the charging machine share a logic control circuit and are respectively controlled by detecting a charging state. The logic control circuit comprises a drive circuit, an I/O control unit, a motor/charging machine control unit and an electric signal detection unit, the DC-DC module is connected with a DC-DC module control unit through the drive circuit, and the drive circuit, the I/O control unit, the motor/charging machine control unit, the electric signal detection unit and the DC-DC module control unit are connected with a whole automobile controller through a CAN bus. Respective internal power supply circuits, I/O circuits and communication circuits of original devices are respectively integrated to form a public circuit, the circuits are modularized and are connected through data buses, and the stability of the system is improved.
