An electric leakage detection apparatus for an electric vehicle including a battery and a chassis, includes a battery voltage sensor; a first series circuit including a first resistor and a first switch connected in series between a first node connected to the battery's negative terminal and a second node connectable to the chassis; a second series circuit including a second resistor and a second switch connected in series between the second node and a third node connected to the positive terminal; a voltage divider connected in parallel to the first series circuit, and including third and fourth resistors connected in series through a fourth node; an analog-digital converter generating a digital signal indicating voltage between the first and fourth nodes; and a control unit determining occurrence of an electric leakage of the battery based on a voltage measured by the analog-digital converter in an electric leakage detection mode.
