The invention discloses a CP signal generation and detection circuit and a charging pile, and relates to the technical field of charging piles. The CP signal generation and detection circuit comprises a power supply input end, a positive voltage input end, a negative voltage input end, a PWM signal input end, a PWM signal output end, a CP signal generation circuit and a CP signal detection circuit. The CP signal generation circuit can generate a CP signal according to the first PWM signal, the first positive voltage and the first negative voltage, and outputs the CP signal to the to-be-charged device. The CP signal detection circuit can collect a CP signal and output a second PWM signal according to the CP signal and the first positive voltage. The circuit for generating the CP signal is relatively simple to implement, the generation of the CP signal is relatively stable, and the generated CP signal can be detected. The invention aims to solve the problems that an existing CP signal generation circuit is complex in circuit implementation, and generation of CP signals is unstable and inaccurate.
