The invention discloses a charging pile circuit and a household charging pile, and relates to the technical field of charging piles. The charging pile circuit comprises a relay circuit, a power supply circuit, an emergency stop circuit, a CP signal generation and detection circuit and a control circuit. The relay circuit can control connection/disconnection of the external alternating-current power supply, when the external alternating-current power supply is in a connection state, the power supply circuit can convert the external alternating-current power supply into a charging power supply to be output, and charging equipment can be charged. Wherein the CP signal generation and detection circuit can generate a stable CP signal, and is used for realizing communication interaction with charging equipment. The sudden stop circuit can disconnect the power supply circuit and the external AC power supply when a charging fault occurs, so as to guarantee the charging safety. Therefore, charging of the charging equipment and communication interaction with the charging equipment can be realized, the external alternating current power supply can be disconnected when a charging fault occurs, the safety is relatively high, the circuit is simple and reliable, and the cost is relatively low.
