Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the explanatory text.

[0039] Such as Figure 1-11 As shown, the present invention provides a DC charging pile with a fault removal function, including: a charging pile body 100 and a charging gun head 200 . The input terminal of the charging pile body 100 is connected to the three-phase power supply, the charging gun head 200 is connected to the output terminal of the charging pile body 100, and a cylindrical plug-in terminal 210 is telescopically set on the end of the charging gun head 200, normally state, the plug end 210 is in a protruding position, and the plug end 210 is plugged into the car charging pin interface to charge the battery pack. When a fault occurs or the battery pack is in the floating charge state for a long time, the control plug end 210 is quickly retracted into the cha...

Abstract

The invention discloses a DC charging pile with fault clearing function, A plug terminal is telescopically arranged on the charging gun head, A through hole is axially formed in the center of the cylinder of the plug end, a plurality of first channels are arranged on the periphery of the through hole, a pair of half cross-sectional bodies are movably arranged in the through hole, a plurality of second channels corresponding to the first channels are arranged on the periphery of the half cross-sectional bodies, and the first channels and the second channels are butted to form a conductive plughole for inserting a charging pin interface of an automobile. A half-conical cavity is axially formed in the cross section of the half-section body, a conical cylinder is telescopically arranged in the semi-conical cavity on the left and right sides, Semi-annular grooves are respectively arranged on the side walls of the left and right semi-conical cavities, an annular bump is correspondingly protruded from the outer periphery of the conical cylinder, the annular bump is confined in the semi-annular groove, the width of the semi-annular groove is larger than the width of the annular bump, andthe diameter is larger than the diameter of the annular bump. The invention solves the technical problem that the fault of the DC charging pile is not removed in time.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a DC charging pile with a fault removal function. Background technique [0002] The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, and cost data printing. The dis...
