The invention discloses an EV pass type automatic charge interface facility comprising a ground electrode, a charge anode, a charge cathode, a pressure sensor, an infrared communication unit, a laser horizontal line generator, a laser vertical line generator, and an insulating member. Socket and plug electrodes of the EV pass type charge interface are arranged and designed in a concentric coaxial arrangement mode; the problem that center misalignment of the charge socket and charge plug and rotational angle error of vertical contact end axis cause failure of plugging during automatic EV charging is solved, the problem that plug connectors are large in size since high charge current of an EV requires large connector electrodes is solved; short circuit is avoided; reliability and stability of automatic charging is improved greatly.
Description
technical field [0001] The invention relates to a facility for automatic charging of electric vehicles. Background technique [0002] The invention relates to a facility for an electric vehicle transmission type automatic charging interface. Generally, the electrodes of the charging socket and plug of the traditional electric vehicle pass-through charging interface are scattered and arranged in the form of three-electrode distribution or multi-row electrode distribution arrangement, such as the Chinese "Electric Vehicle Pass-through Charging Interface" standard V20100427, which is not convenient for electric vehicles. The automatic alignment and automatic insertion of the automatic charging socket and the plug, and the elimination of the insertion error during alignment. Contents of the invention [0003] The problem to be solved by the invention [0004] In the present invention, the socket and plug electrode arrangement of the electric vehicle transmission charging int...
