Zusammenfassung:The utility model discloses a CP wake-up circuit of an electric automobile. The CP wake-up circuit comprises a power supply input unit, a CP signal trigger unit and a wake-up unit, the power supply input unit is used for accessing a power supply VCC signal and outputting a high-level signal to the awakening unit when receiving a driving signal provided by the power supply input unit; the CP signal triggering unit is connected with the power supply input unit and is used for accessing a CP signal and providing a CP driving signal for the power supply input unit after the CP signal is accessed; and the wake-up unit is connected with the power supply input unit and is used for outputting a pulse signal to a battery management system BMS in real time after receiving the high level signal output by the power supply input unit 100 so as to wake up the battery management system BMS. According to the utility model, through the combination of the MOS tube and the timer, the power supply of the wake-up circuit is contr
