A charging post controller with various functional modules connected by a PCB, and a charging post thereof. The controller includes a monitoring unit (1), a direct-current main loop unit (2) and a mounting and fixing unit (3), wherein the monitoring unit (1) comprises a PCB (11) and an electronic circuit forming electrically connected functional modules (4), and the functional modules (4) are mounted on the mounting and fixing unit (3), to form a laminated arrangement structure among the monitoring unit (1), the direct-current main loop unit (2) and the mounting and fixing unit (3). A charging post using the controller has a relatively high degree of integration, relatively small overall volume and relatively low comprehensive cost, and is relatively easily promoted and applied.
