The invention relates to the technical field of new energy automobile power supply, and in particular relates to a new energy automobile power supply system which comprises a DC/DC voltage conversionmodule, a battery power supply system monitoring module, a power supply power consumption module, a bus communication module and a high-voltage power distribution module. After the new energy automobile power supply system adopts a hybrid electric automobile and the electric automobile adopts a DC/DC converter, an alternating-current generator can be omitted. The power battery capacity of the electric automobile is very large, so that a power battery is used as a power supply, the DC/DC converter can be used for charging a low-voltage storage battery, and an original alternating-current generator can be omitted. The power distribution scheme, layout, grounding loop and the like of the new energy automobile power supply system supply power to a load well, high voltage adjustment precision and low noise are achieved, and the problems of interference, oscillation, overload and the like among circuits in the system are avoided.
