Disclosed are an apparatus for diagnosing a relay contact of an electric vehicle and a method thereof. The method includes measuring a first voltage input from a high-voltage battery to an inverter; comparing the first voltage with a second voltage output through the high-voltage battery; identifying a detection time point of the first voltage when the first voltage is greater than the second voltage; and determining whether a high-voltage relay, which intermits an output voltage of the high-voltage battery, is malfunctioned based on the identified detection time point. |
