The invention discloses an anti-theft circuit of an electric vehicle. The anti-theft circuit comprises a signal input module, a voltage dividing module, a voltage stabilizing module and a control module, the output end of the signal input module is connected with the input end of the voltage division module; the output end of the voltage dividing module is connected with the input end of the control module; the output end of the voltage dividing module is further connected with the negative electrode of the voltage stabilizing module, and the positive electrode of the voltage stabilizing module is grounded. The signal input module is used for receiving a Hall signal generated when a motor of the electric vehicle rotates and transmitting the Hall signal to the voltage dividing module; the voltage division module is used for performing voltage division processing on the Hall signal to obtain a voltage division signal, and the voltage division signal is grounded after passing through the voltage stabilization mo
