High Voltage Interlock Circuit Detection and Troubleshooting
The design of the high-voltage circuit interlock function is proposed for the reliability of the high-voltage circuit connection. Hazardous Voltage Interlocking Loop, also known as High Voltage Interlocking Loop (HVIL), is a typical interlocking system that uses electrical signals to check the electrical integrity of the entire module, wires and connectors. When the high-voltage safety management system detects that a certain connection is disconnected or the connection does not reach the expected reliability, the safety management system will cut off the output of the relevant power supply directly or through the vehicle controller and issue an audible and visual alarm until the fault occurs. completely excluded.
