Charging gun design standard, what is the difference between American standard, European standard and national standard charging gun

As for the “national standard” (GB/T), it is only used in China and has geographical limitations. From a technical point of view, the “national standard” is actually an improved agreement based on the “European standard”. The agreement, issued by the Ministry of Industry and Information Technology, is a “recommended” standard and does not have administrative force. This is also one of the reasons why the charging standards in various regions of China cannot be unified.

For charging guns of different standards, there are both similarities and differences in their designs. For example, the national standard AC charging gun has something in common with the European standard charging gun: the pins and sockets are the same, and the temperature sensor is on the gun head; the difference: the voltage is 250V, there are mechanical locks, micro switches, and the pins are mounted on the gun head. . Through comparative analysis, the work load of the national standard AC charging gun design is slightly larger than that of the European standard AC charging gun design. In terms of difficulty, the European standard AC charging gun design has not been reduced. The design difficulty lies in the connection structure between the plug and the main body. Easy to assemble, the product structure design engineer should have a unique solution, the design of the national standard AC charging gun focuses on the main part, the two have different emphases, the same goal, and must satisfy the ultimate user experience.
