The invention provides a power supply system and method for a direct-current fast charging station of an electric vehicle and the fast charging station, and the power supply system comprises a communication module which is used for obtaining the power capacity of a transformer and the output power of each charging pile; the data processing module is used for obtaining the total charging power according to the output power of each charging pile; the judgment module is used for judging whether the total charging power is greater than the power capacity of the transformer or not and outputting a judgment result; and the control module is used for adjusting the allowable output power of each charging pile based on the electric power capacity of the transformer and the judgment result so as to meet the load management of the charging station. The allowable output power of the charging pile is adjusted according to the electric power capacity of the transformer, and the design capacity of the transformer is reduced while continuous charging of the electric vehicle is met, so that the construction cost of the whole charging station is greatly reduced and saved.
