The invention discloses a new energy automobile electric leakage detection device which comprises a battery, first to fourth resistors, a first capacitor, a second capacitor, a field effect transistor, a first triode, a second triode, a potentiometer, an optical coupler, a time base integrated chip, a light emitting diode, a switch and a loudspeaker. A grid electrode of a field effect transistor serves as a probe; when the field-effect tube senses the current, the field-effect tube is conducted; the first triode is electrified and conducted; a light-emitting tube in the optical coupler is switched on to be lightened; a photosensitive tube in the optical coupler is conducted; the time base integrated chip sends a control signal to the second triode after receiving the trigger signal, so that the second triode is conducted; according to the invention, the inductive probe is formed through the field effect transistor, wherein the electrified position is determined through induction, direct contact is not needed
