The invention relates to a prefabricated modularized intelligent electric car electric charging station which comprises a plurality of prefabricated box bodies, wherein a charging set cabinet, a charging rack, battery maintenance equipment, a monitoring cabinet and a monitoring room are orderly arranged in each box body according to function construction of the various parts; the charging racks in the box bodies are arranged on one side uniformly; the various prefabricated box bodies are arranged in two columns; an electric charging robot passage is arranged along the distributed direction of the box bodies in a stretching manner on one side of each column of box bodies where the charging racks are arranged; electric car passages are arranged on the other sides of the electric charging robot passages; the two electric car passages are adjacent; and the charging racks in the prefabricated box bodies are distributed on one side facing towards the electric charging robot passages. According to the prefabricated modularized intelligent electric car electric charging station, connection among electric cables among the equipment are completed in a manufacturing shop, and after the box bodies are transported to the site, only the following procedures are required to be done: the box bodies are fixed on the ground of the site and directly connected with a main incoming cable, and simple debugging is performed. The prefabricated modularized intelligent electric car electric charging station facilitates quick movement, assembly and combination; quick construction is realized; a station construction cycle is shortened; the cost is low; and the degree of automation is high.
