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 module; the voltage stabilization module is used for carrying out voltage stabilization processing on the voltage division signal to obtain a voltage stabilization Hall signal and outputting the voltage stabilization Hall signal to the control module; and the control module receives the voltage-stabilizing Hall signal, and if the state of the motor at the moment is a shutdown state, anti-theft alarm information is generated. The anti-theft effect of the electric vehicle can be effectively improved.

    本发明公开了一种电动车防盗电路,包括:信号输入模块、分压模块、稳压模块和控制模块;信号输入模块的输出端与分压模块的输入端连接;分压模块的输出端与控制模块的输入端连接;分压模块的输出端还与稳压模块的负极连接,稳压模块的正极接地;信号输入模块用于接收电动车的电机转动时产生的霍尔信号,并将霍尔信号传输至分压模块;分压模块用于对霍尔信号进行分压处理得到分压信号,将分压信号经过稳压模块后接地;稳压模块用于对分压信号进行稳压处理得到稳压霍尔信号,并将稳压霍尔信号输出到控制模块中;控制模块接收到稳压霍尔信号,若此时电机的状态为关机状态,则生成防盗警报信息。本发明能够有效提高电动车的防盗效果。
