HIGH-VOLTAGE INTERLOCKING DEVICE AND METHOD FOR DETECTING THE HIGH-VOLTAGE INTERLOCKING DEVICE

[0001] The application provides a high-voltage interlocking device and a method for detecting the high-voltage interlocking device, and relates to the field of battery power. The high-voltage interlocking device includes: a first resistance module (R1); a first switch module (K1), a second connection end of the first switch module (K1) being connected to a first reference potential (GND1) through a third resistance module (R3), and a control terminal (C1) of the first switch module (K1) being configured to receive a first driving signal, to enable the first switch module (K1) to be turned on or off according to the first driving signal; a second resistance module (R2), another end of the second resistance module (R2) being connected to a second reference potential (GND2); a fourth resistance module (R4); a second switch module (K2), a second connection end of the second switch module (K2) being connected to a third reference potential (GND3) through a fifth resistance module (R5); a fault detection module (11), configured to determine a fault of the high-voltage component under detection (G) according to a first detection signal. According to the high-voltage interlocking device and method for detecting the high-voltage interlocking device provided by embodiments of the application, comprehensiveness of fault detection can be improved.
