The invention discloses a separated type alternating current charging pile. The separated type alternating current charging pile comprises a power bank and a power supply device; the power bank is used for converting a current and a voltage into a current and a voltage which are capable of charging a battery; and the power supply device is connected with the power bank in an electric conductive manner so that current is transmitted between the power supply device and the power bank. According to the separated type alternating current charging pile, the separated type alternating current charging pile can be used as a fixed charging pile for charging, and the power bank can also be taken off to be taken with a user; the charging can be made anywhere with a power supply socket, and the separated type alternating current charging pile can be suitable for various scenes needing to be charged.
