A new energy automobile power management system comprises a low-voltage power distribution unit, a high-voltage power distribution unit, an insulation monitoring module, a direct-current conversion module and a power management controller. The low-voltage power distribution unit comprises a relay and a fuse. The high-voltage power distribution unit comprises a high-voltage relay, a high-voltage contactor, a high-voltage fuse and a high-voltage connector. The detection end of the insulation monitoring module is connected with the anode and cathode of the high-voltage loop of the high-voltage power distribution unit and a system ground wire. The high-voltage input end of the direct-current conversion module is connected with the high-voltage connector, and the low-voltage power output end ofthe direct-current conversion module is connected with the low-voltage input end of the low-voltage power distribution unit. And the power management controller communicates with other parts of the whole vehicle through a CAN bus. The system is high in integration level, complete in function, good in reliability and convenient in whole vehicle arrangement; fault diagnosis and maintenance are facilitated; the reliability is good and the anti-interference capability is strong; external part high-low voltage fault judgment is automatically carried out, a high-low voltage loop is disconnected with high authority, and personnel and whole vehicle safety is guaranteed.
