The invention discloses a high-voltage interlocking circuit and a detection method thereof, and relates to the field of batteries. The high-voltage interlocking circuit comprises a signal isolation conversion module, the input end of the signal isolation conversion module is connected with one end of a to-be-detected high-voltage component, the output end of the signal isolation conversion module is connected with a fault detection module, and the signal isolation conversion module is used for converting a first target electric signal at one end of the to-be-detected high-voltage component into a first to-be-detected electric signal on the premise that the to-be-detected high-voltage component is isolated from the fault detection module. and the other end of the to-be-detected high-voltage component is connected with a first power supply end; and the interlocking circuit also comprises a fault detection module used for determining the fault of the to-be-detected high-voltage component based on the first to-be-detected electric signal. According to the high-voltage interlocking circuit and the detection method thereof provided by the embodiment of the invention, the damage of external large voltage to the fault detection module is avoided, and the safety of the high-voltage interlocking circuit can be improved.
