The application provides a high voltage interlock circuit and a detection method thereof, the high voltage interlock circuit comprises: a signal isolation conversion module, an input terminal of the signal isolation conversion module is connected to one terminal of a high voltage component to be detected, and an output terminal of the signal isolation conversion module is connected to a fault detection module, the signal isolation conversion module is configured to convert a first target electrical signal at the one terminal of the high voltage component to be detected into a first electrical signal to be detected on the premise of ensuring that the high voltage component to be detected is isolated from the fault detection module, wherein the other terminal of the high voltage component to be detected is connected to a first power supply terminal; the fault detection module configured to determine a fault of the high voltage component to be detected based on the first electrical signal to be detected. The high voltage interlock device and the detection method thereof provided by the embodiments of the application can avoid the damage to the fault detection module caused by large external voltage, and improve the safety of the high voltage interlock device
