Abstract In recent years, China has successively issued an electric vehicle and charging construction subsidies, charging station construction in the phase of rapid expansion, but due to the charging station design is not reasonable, the charging station of high investment and low efficiency of embarrassment. This paper analyzes the difficulties of charging station layout, the total level of the charger, transformer capacity selection in the parking charge parking mode and station traffic organization analysis, according to the charging position of different vehicles and different area of natural terrain, the charging station the total level of reasonable arrangement. Through to the Xiamen station, charging the charger parameters of passenger car of Xiamen city the main models of charging parameters analysis, put forward the selection scheme of charging contrast analysis, optimization program is given the choice of charger. The charger of charging station load factor, the transformer operation data analysis, given a suitable charger public charging stations need to value, the final selection of charging station of distribution transformer capacity.
