The present invention discloses a portable 7KW alternating current charging pile. The portable 7KW alternating current charging pile comprises a power line, a control box and a charging gun, the control box is electrically connected with the power line, and the charging gun is electrically connected with the control box; the control box comprises a microcontroller, a power supply wiring terminal,a power supply module, a relay, an LCD display screen and a control button. The power line is electrically connected with the power supply wiring terminal; the power supply module is electrically connected with a phase line and a zero line led out from the power supply wiring terminal; a phase line terminal in the charging gun is connected in series with one normally open switch in the relay and then is electrically connected with a phase line led out from the power supply terminal; and a zero line wiring end in the charging gun is electrically connected with the zero line led out of the powersupply wiring terminal after being connected with the other normally open switch in the relay in series, and a ground wire wiring end in the charging gun is electrically connected with a ground wireled out of the power supply wiring terminal. The portable 7KW alternating current charging pile has the advantages of being small in size and convenient to carry, and the charging efficiency of a newenergy vehicle can be improved.
