Abstract
An electric leakage detecting apparatus includes: a first voltage-dividing circuit; a second voltage-dividing circuit; a first switch which is inserted in a line connecting the first voltage-dividing circuit and the ground connection resistance; a second switch which is inserted in a line connecting the second voltage-dividing circuit and the ground connection resistance; a first voltage detecting circuit which detects an output voltage of the first voltage-dividing circuit; a second voltage detecting circuit which detects an output voltage of the second voltage-dividing circuit; and a judging circuit which judges whether the electric leakage of the high voltage battery occurs or not on the basis of the output voltage of the first voltage-dividing circuit in a case that the first switch is in ON state and the output voltage of the second voltage-dividing circuit in a case that the second switch is in ON state.
