The HVIL (High Voltage Interlock Loop) daisy-chains through all HV connectors in an EV. Each HV connector contains a low-voltage shorting bridge. If any HV connector is opened the loop breaks and the BMS shuts down HV.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | Loop In | HVIL signal input from previous connector | I/O |
| 2 | Loop Out | HVIL signal output to next connector | I/O |
