EV car electric charging characteristics
With the rapid popularity of new energy electric vehicles, charging guns are increasingly used in daily life. Charging gun design, as a terminal equipment for electric vehicle charging, needs to consider many details, including appearance design, structural design, material technology, mold opening and injection molding, production and manufacturing and other factors. Whether the structural design of the charging gun is reasonable or not is directly related to the realization of the functions of the charging gun and the reliability of its performance. The following car charging gun editor will introduce in detail the basic requirements for the structural design of the charging gun.
1. User-friendly and convenient operation
The structural design of the charging gun needs to meet the requirements for the installation of the charging power module and the main circuit of the appliance and the control system. It is necessary to consider the heat dissipation of the charging module, the wiring of the main circuit of the appliance and electrical safety issues to ensure the realization of the equipment functions and the stability of the internal structure. sex. At the same time, the charging gun is a terminal device used for charging new energy pure electric vehicles. It requires a man-machine interface, card swiping and button operation. The LCD interface can display data such as charging amount, cost, charging time, etc., so when designing and operating The user-friendliness and convenience of operation and use need to be considered when designing the interface.
2. Strong anti-electromagnetic interference ability
When an electric vehicle battery is being charged, its charging and discharging efficiency will be affected by surrounding environmental conditions, especially electromagnetic interference. At normal temperature, the battery has a strong ability to accept charge and discharge. As the ambient temperature decreases, its ability to accept charge will also decrease. Therefore, when designing the structure of the charging gun, it must have strong anti-electromagnetic interference capabilities to prevent excessive electromagnetic interference from affecting its charging efficiency.
3. Parts design
The internal structure design of the charging gun should adopt a modular design according to the requirements of the electrical function, and each electrical functional unit should be installed on a whole board. At the same time, rational layout is achieved according to the wiring requirements of the product’s electrical schematic diagram. The main circuit wiring in the pile body is designed from bottom to top, from left to right. Therefore, the internal electrical device layout from bottom to top is the AC incoming line part, the rectifier module part, the DC output part, the charging interface and the control unit. At the same time, strong and weak electricity must be separated during wiring to reduce electromagnetic interference to signal lines.
4. Anti-corrosion design
The electric vehicle charging gun is an outdoor facility. During the entire design process, in order to adapt to the influence of extreme outdoor weather, a stainless steel structure should be used to prevent dust, rain, and extreme bad weather. At the same time, the display area and card swiping area of the electric vehicle charging gun should be made of PC material. This material has strong corrosion resistance and has the advantages of flame retardant and self-extinguishing. It has good toughness and strength and can withstand heavy pressure. role.
The explosive growth of the charging gun market has also exposed a variety of problems: imperfect market access, standards, technical capabilities, and quality control; there are many new players in the industry, insufficient R&D and production accumulation; uneven quality of products, and failure rates High, scrapped quickly, etc. Therefore, in the early stage of product design, various design requirements must be sorted out, and the charging gun structural design must be systematically and rationally combined with the external application environment and electrical requirements. Of course, appearance design is also very important. The structural design of the charging gun should be based on ensuring the realization of the functions of the device. The shape of the charging gun should be simple and intuitive, with a unique and creative image, so that it can be more easily accepted by users.
