The invention discloses an integrated direct current charging pile, and mainly solves the problems that schematic diagram drawing and PCB manufacturing of an existing direct current charging pile are difficult, and a real-time control function and a transaction analysis and processing function are difficult to meet at the same time. The direct current charging pile comprises a main control module and a power control module which are connected through an RS485 communication circuit; a man-machine interaction display module, a read-write card module, an electric energy metering module, a charging interface module and a charging monitoring module which are connected with the main control module; and a three-phase alternating current input power supply connected with the power control module. Through the design, the direct current charging pile control system is divided into two layers of structures, the main control module realizes man-machine interaction and networking monitoring functions, and a controller in the main control module adopts an ARM processor; and the power control module realizes charging control and fault protection functions, and the controller adopts a DSP. Through the design, the manufacturing difficulty of the PCB is reduced, and a real-time control function and a transaction analysis and processing function can be met.
