The invention provides a high-voltage interlocking diagnosis circuit, a high-voltage interlocking diagnosis method and an electric vehicle. The high-voltage interlocking diagnosis circuit comprises a control module, a high-voltage interlocking module, an output sampling module, an input sampling module and a power supply module. Wherein the input end and the output end of the high-voltage interlocking module are connected with an external circuit to form a loop. The control module, the high-voltage interlocking module and the power supply module are connected in series to form a main circuit of the high-voltage interlocking diagnosis circuit. An output sampling module and an input sampling module in the high-voltage interlocking diagnosis circuit are respectively connected with a high-voltage interlocking module and are used for acquiring the input voltage and the output voltage of the high-voltage interlocking module. The control module can obtain the input voltage and the output voltage through the output sampling module and the input sampling module so as to diagnose the external circuit. According to the high-voltage interlocking diagnosis circuit, the reliability of a diagnosis result and the accuracy of diagnosis are improved.
