Safety circuit for a power system of a vehicle and method for controlling the safety circuit

A safety circuit for a power system of a vehicle, the safety circuit comprising:

• a hazardous voltage interlock loop circuit configured to disconnect a high-voltage energy source from a high-voltage system, the HVIL-circuit comprising a contactor arranged between the high-voltage energy source and the high-voltage system, and a HVIL control unit;
• a current meter arranged to measure a current between the high-voltage energy source and the high-voltage system;
• a fuse arranged between the high-voltage energy source and the high-voltage system;
• a switching circuit arranged to control the contactor of the HVIL-circuit;
• and
• a safety circuit control unit connected to the current meter to receive a current measurement of a current running through the contactor and to the switching circuit for controlling the contactor, wherein the safety circuit control unit is configured to:
• if the HVIL control unit provides a control signal to the switching circuit to open the contactor, and if the current measurement exceeds a first threshold current value, control the switching circuit to delay the opening of the contactor by a controllable time period.
