The invention discloses an electric vehicle safety starting method and a system. According to the conscious operation of an electric vehicle ignition key and the identification of an obvious optical signal hint by a driver, the safety staring process of the electric vehicle can be achieved. The safety starting system of the electric vehicle is correspondingly provided. The system comprises a CAN bus combination instrument, an integrated power supply, a battery management system, a high-voltage main positive contactor, an accelerator pedal, a motor controller, a state detector switch for a high-voltage device hatch, a whole vehicle control unit, a state detector switch for a charging hatch, an ignition key switch, a self-detecting indicator light and a READY indicator light. By adding operation logic of an ignition key START gear onto the starting process, and adopting a two-grade signal device which comprises the self-detecting indicator light and the READY indicator light, the driver can conveniently observe the starting state of the electric vehicle. Accordingly, the dangerous caused by unconscious vehicle staring of the driver can be avoided, and the starting safety of the electric vehicle can be improved.
