The invention discloses an AC charging CP signal wake-up and sleep circuit for an electric vehicle. The AC charging CP signal wake-up and sleep circuit comprises a 5V constant power module, a CPPWM signal conversion module, a D trigger module, a selection module, a BMS main control chip and an MCU signal output module. The 5V constant power module is respectively connected with the CPPWM signal conversion module, the D trigger module and the selection module, and provides continuous 5V direct current output; the CPPWM signal conversion module is respectively connected with the charging gun CPPWM input module and the D trigger module; the BMS main control chip is connected with the MCU signal output module, the MCU signal output module comprises two signal output ends, namely an MCUCPCLR and an MCUPOWERLOCK, the output end MCUCPCLR is connected with the D trigger module, and the output end MCUPOWERLOCK is connected with the selection module; and the selection module is connected with the D trigger module. The method not only solves the problem of CP wake-up, but also solves the problem that the BMS continues to work and damages the storage battery after charging is completed, and has important production practice significance.
