The invention relates to a hazardous voltage interlock loop, HVIL, system (10), comprising a first HVIL circuit (12) being associated with a first high voltage bus (52) and a second HVIL circuit (14) being associated with a second high voltage bus (54), wherein the first and second high voltage buses (52, 54) are separated and not electrically connected to each other. The system further comprises a galvanically isolated relay (16) connected to the first and second HVIL circuits, wherein the galvanically isolated relay is configured to open the first HVIL circuit when no electrical current is flowing in at least a portion of the second HVIL circuit comprising the galvanically isolated relay. The present invention also relates to a vehicle comprising such a system. The present invention also relates to a method of operating a hazardous voltage interlock loop system.
