The invention relates to an electric vehicle direct-current charging pile signal line integrated port and an electric vehicle charging pile. The electric vehicle direct-current charging pile signal line integrated port comprises low-voltage ports located in a first power strip and high-voltage ports located in a second power strip. The low-voltage ports of the first power strip are connected withan emergency stop signal line, a detection point 1 signal line, an electronic lock signal line, an S+S- communication line, a K1K2 state feedback signal line, a K3K4 state feedback signal line, an electric energy meter metering pulse signal line and a signal ground wire; and the high-voltage ports of the second power strip are connected with a K1K2 contactor front end voltage measuring line, a K1K2 contactor rear end voltage measuring line, a L1/L2/L3/N, and a three-hole power socket (L/N/PE). According to the invention, integrated leading-out of signal lines in production, maintenance and detection of the electric vehicle direct current charging pile can be realized, the safety and reliability of the detection process are improved, and the detection and maintenance efficiency is enhanced.The method is simple and easy to implement and convenient to use.
