The invention belongs to the technical field of new energy, and provides a CC2 single wake-up circuit of a BMS, a wake-up method and an electric automobile, which solve the technical problem that the wake-up requirement cannot be met by using an A + signal to wake up the BMS in the traditional standard, and the technical scheme is as follows: the CC2 single wake-up circuit comprises a PMOS transistor, the gate pole of the PMOS transistor is connected with a direct-current power supply through a delay capacitor, and the gate pole of the PMOS transistor is connected with the direct-current power supply; the source electrode of the PMOS tube is connected with the direct current power supply, and the drain electrode of the PMOS tube is connected to the BMS through the enabling pin of the DCDC; a charging gun is connected to the wake-up circuit through the charging gun switch; when the charging gun switch is switched off, the output voltage of the enabling pin of the DCDC is 0V, and the BMS is dormant; when the charging gun switch is switched on, the delay capacitor is discharged, the PMOS tube is switched on, the output voltage of the enabling pin of the DCDC is increased from 0V to a direct current power supply voltage value, the BMS is awakened, the capacitor is charged, the voltage of one side, close to the PMOS tube, of the capacitor is increased to the direct current power supply voltage value, the gate voltage and the source voltage of the PMOS are equal, the PMOS tube is switched off, and the output voltage of the enabling pin of the DCDC is changed to 0V.

    本发明属于新能源技术领域,提供了一种BMS的CC2单次唤醒电路、唤醒方法及电动汽车,它解决传统标准使用的是A+信号唤醒BMS无法满足唤醒要求的技术问题,其技术方案为:包括:PMOS管,所述PMOS管的门极通过延时电容和直流电源相连,PMOS管的源极与直流电源相连,PMOS管的漏极通过DCDC的使能脚连接至BMS;充电枪开关,充电枪通过所述充电枪开关接入唤醒电路;当充电枪开关断开时,DCDC的使能脚输出电压为0V,BMS休眠;当充电枪开关接通时,延时电容放电,PMOS管导通,DCDC的使能脚输出电压由0V升高至直流电源电压值,唤醒BMS,电容充电,电容靠近PMOS管一侧的电压上升到直流电源电压值,PMOS的门极电压和源极电压相等,PMOS管截止,DCDC使能脚输出电压变为0V。
