The invention relates to a vehicle-mounted power supply system for an electric automobile. The vehicle-mounted power supply system for the electric automobile is characterized by comprising a CAN module, a center control module, a low-voltage control output circuit, a power battery pack, a detection selection circuit and a high-voltage control output circuit, one passage of the power battery pack is directly connected with the high-voltage control output circuit while the other passage is connected with the detection selection circuit through a gathering wire harness, the detection selection circuit is connected with the low-voltage control output circuit, the center control module is connected with an automobile controller through the CAN module, and the center control module is respectively connected with the low-voltage control output circuit, detection selection circuit and high-voltage control output circuit. The vehicle-mounted power supply system for the electric automobile highly integrates the high-voltage current and low-voltage current output, a constant-current battery module and a DC-DC converter are omitted, and the cost is lowered; the omitted spare parts do not need arrangement, the total arrangement difficulty of the automobile is reduced, and the effective use space of the automobile is increased; the volume of the integrated vehicle-mounted power supply system is reduced, the splicing piece number can be reduced, and accordingly the vehicle reliability is improved.
