Electric automobile charging gun with charging control function

Abstract

The invention discloses an electric automobile charging gun with a charging control function. The electric automobile charging gun comprises a gun body provided with a charging plug, wherein the gun body is connected with a charging pile through a cable. The electric automobile charging gun further comprises a main control panel, a handle, an operation panel, a card reader, a micro printer, a protection cover and a suction disc, wherein the main control panel is arranged inside the gun body, the handle, the operation panel, the card reader and the micro printer are all arranged on the gun body, the protection cover is arranged on the periphery of the charging plug at the front end of the gun body, and the suction disc is arranged on a cover opening of the protection cover; the main control panel comprises a main control unit, a charging module, a meter module, an input and output module, a card reader read-write module, a storage module, a communication module and a printing driving circuit, and the charging module, the meter module, the input and output module, the card reader read-write module, the storage module, the communication module and the printing driving circuit are respectively connected with the main control unit. The electric automobile charging gun achieves the purpose that charging control is conducted on the charging gun, is integrated with card reading, metering, billing, printing functions, achieves remote operation, and reduces the effect of harmonic waves on communications in the charging process.

Description

technical field [0001] The invention relates to a charging connection device for an electric vehicle, in particular to a charging gun for an electric vehicle with a charging control function. Background technique [0002] After years of research and development by automobile manufacturers and the government's policy support for the electric vehicle industry, my country's electric vehicle industry has begun to show explosive growth, especially in the key battery technology, which has achieved a major breakthrough and is in a leading position in the world. However, the matching electric vehicle charging pile technology has always been a shackle restricting the widespread promotion of electric vehicles. Currently popular charging piles for electric vehicles generally use a charging pile body with a display screen and a towable charging gun structure. Users need to operate the display screen and charging gun at both ends separately. Damage, easy to enter rainwater, complex inte...

Problems solved by technology

Currently popular charging piles for electric vehicles generally use a charging pile body with a display screen and a towable charging gun structure. Users need to operate the display screen and charging gun at both ends separately. Damage, easy to enter rainwater, complex internal structure and high cost, need to build independent protective cover and other facilities during installation, which causes a lot of inconvenience to the promotion of electric vehicle charging piles, and also limits the large-scale promotion of electric vehicles

[0003] In the electric vehicle charging gun utility model patent with application number 201220614428.1, a charging gun with a waterproof sleeve is designed, which can improve the protection level of the charging gun and increase the convenience of use and maintenance, but the charging gun itself does not have the control function. The user needs to operate back and forth between the pile body and the charging gun; in the invention patent of the vehicle charging system with charging efficiency control and adaptive charging service function with the application number 201010512855.4, a charging gun with charging protection function is designed, mainly Realize power statistics and high current safety protection functions, but this method lacks the visual interface of the charging gun, and cannot realize all charging control functions at one end, which is greatly lacking in practicability and convenience

[0004] The existing electric vehicle charger is generally 4KW ~ 200KW, the power is relatively large, and it will generate a lot of harmonics during operation, which will seriously affect the communication effect of other components, and each charging for six to ten hours will also affect the operation Part of the impact is caused by the safety of personnel, which cannot meet the charging needs of the majority of users.

[0005] In actual operation, most charging pile equipment needs to be installed in outdoor locations such as stations, residential areas, and roadsides, and it is impossible to build matching safety protection facilities. Charging piles with display screens are generally large in size, and due to the installation of the display screen Therefore, there is an urgent need for a new, movable, multi-functional electric vehicle charging gun with charging control function, which fundamentally promotes the development of electric vehicles. large-scale promotion
