Abstract
Disclosed is an electrical leakage diagnosis apparatus for a vehicle which uses an insulation resistance sensor. The apparatus includes an insulation resistance sensor; a main switching part; and a battery power management part configured to terminate the operation of a driving part so as to control a driving motor of a vehicle when the value of a first insulation resistance outputted from the insulation resistance sensor is less than a previously set threshold value, and to determine that an insulation breakage has occurred in one or more driving components when the value of a second insulation resistance, measured after terminations of the driving components, exceeds the threshold value and to terminate the operation of the vehicle by turning off the main switching part so that electrical power supplied from the high voltage battery to the electrical field loads of a vehicle is disconnected.
