Claim 1:
2. The high-voltage interlocking device of claim 1, wherein,
the first driving signal and the second driving signal are both pulse signals,
the fault detection module is configured to:
under a condition that a high-level voltage of the first detection signal is equal to a first reference short power supply voltage, and/or a low-level voltage of the first detection signal is equal to a second reference short power supply voltage, determine that the short power supply fault occurs in the high-voltage component under detection;
under a condition that the high-level voltage of the first detection signal is equal to a first reference open-circuit voltage, and/or the low-level voltage of the first detection signal is equal to a second reference open-circuit voltage, determine that the open-circuit fault occurs in the high-voltage component under detection;
under a condition that the high-level voltage of the first detection signal is equal to a first reference short-ground voltage, and/or the low-level voltage of the first detection signal is equal to a second reference short-ground voltage, determine that the short-ground fault occurs in the high-voltage component under detection.
