The invention provides an AC-DC integrated charging pile which comprises a power supply input protection apparatus in electric connection with an external power supply source. The output end of the power supply input protection apparatus is provided with an AC charging gun in electrical connection with the output end of the power supply input protection apparatus through an AC switch apparatus. A control apparatus in the charging pile is electrically connected with the power supply input protection apparatus, the AC switch apparatus and the AC charging gun. The charging pile further comprises an AC-DC conversion apparatus in electrical connection with the control apparatus, a DC switch apparatus and a DC charging gun. According to the invention, the charging pile combines an AC charging unit and a DC charging unit together, and a user can choose different charging guns to control the charging units for charging. In this way, AC charging and DC charging integration becomes available, reducing the construction costs for charging piles, increasing the utilization efficiency of charging piles and saving resources.
