The present disclosure discloses a power system of a new-energy vehicle and the new-energy vehicle. The power system of the new-energy vehicle includes only one driving electric motor, the power system further includes a power coupling device and an outputting device, and the outputting device includes a primary outputting device and a plurality of auxiliary outputting devices; the power coupling device is provided between the driving electric motor and the outputting device, and is configured to realize power transmission and on-off control between the driving electric motor and the outputting device; the primary outputting device is configured to provide power for travelling of the new-energy vehicle; and the auxiliary outputting devices are configured to provide power to auxiliary driving systems of the new-energy vehicle. The above technical solutions, by using the single electric motor, realize diversified outputting for the new-energy vehicle, and, by using the coupling integration technique, reduce the power sources, save the occupied space, and reduce the vehicle weight and the manufacturing cost. The technical solutions can improve the load rate of the low-speed area of the driving electric motor, thereby improving the driving efficiency. The technical solutions can effectively simplify the control logic, improve the safety of the controlling system, and realize controlling diversity.
