The invention provides an alternating current charging pile compatible with three-phase power and single-phase power and a charging method, and belongs to the technical field of alternating current charging piles. The charging pile comprises a control detection module, an ACDC power module and a charging gun. The control detection module comprises an MCU, a change-over switch, a power supply detection unit, a CP detection unit, a first relay and a second relay; the MCU is connected with the change-over switch, the power supply detection unit, the CP detection unit, the first relay, the second relay and the ACDC power supply module; the ACDC power supply module is connected with the power supply detection unit and the CP detection unit; the output end of the first relay is connected with pins A and N of the charging gun; the output end of the second relay is connected with pins B and C of the charging gun; a pin PE of the charging gun is used for connecting a grounding end of a power grid; the CP detection unit is connected with the charging gun; the power supply detection unit is used for connecting A-phase power, B-phase power, C-phase power and a zero line of a power grid. The alternating current charging pile has the advantage that the compatibility of the alternating current charging pile is greatly improved.
