The invention relates to the technical field of circuit control, particularly provides an insulation fault position detection method and device, a medium and a vehicle, and aims to solve the problem of how to more accurately detect the insulation fault position of an electric vehicle. In order to achieve the purpose, the insulation fault position detection method comprises the steps of obtaining a first insulation resistance average value of an insulation detection circuit when a first switch and a second switch are both closed, and obtaining a second insulation resistance average value of the insulation detection circuit when the first switch and the second switch are both opened, according to the first insulation resistance average value and the second insulation resistance average value, the fault position of the insulation fault is obtained, and the fault position comprises the power battery and the vehicle end high-voltage load end. Through the configuration mode, the insulation fault position of the electric vehicle can be accurately detected.
