The invention provides a high-voltage interlocking system, an electric driving system, a power assembly and an electric vehicle, and relates to the technical field of electric vehicles. The input end of the high-voltage interlocking system is connected with the power battery pack, and the high-voltage interlocking detection system comprises a high-voltage distribution box and a controller. The high-voltage distribution box comprises a direct-current busbar and at least two groups of output ends; the input end of the high-voltage distribution box is the input end of the high-voltage interlocking system, and the input end of the high-voltage distribution box is connected with at least two groups of output ends through a direct-current busbar; the at least two groups of output ends are used for connecting the input end of the high-voltage loop and the input end of the high-voltage device; the controller determines whether the high-voltage loop has an interlocking fault according to the output voltage of the power battery pack and the input voltage of the high-voltage loop; and determining whether the high-voltage device has an interlocking fault according to the output voltage of the power battery pack and the input voltage of the high-voltage device. By means of the high-voltage interlocking system, maintenance and troubleshooting are facilitated, and the occupied size and cost are reduced.
