Introduction: A connector is a coupling device that connects electrical terminals to form a circuit. Connectors can be used to connect wires, circuits, printed circuit boards, and electronic components. The following describes the charging pile interface and cable standards.

Description: Energy-saving and environmentally friendly electric vehicles have become an inevitable trend in the automotive industry. However, while car companies in various countries are focusing on the development of electric vehicle technology, the charging standards of electric vehicles are also an important factor affecting their popularity.

The following is a summary of some charging connector devices on the market:

First, the Combo socket allows electric vehicles to charge slowly and quickly, and is currently the most widely used socket type in Europe.

Second, CHAdeMO is the abbreviation of CHArge de Move, which is a CHAdeMO socket supported by Nissan and Mitsubishi Motors in Japan.

Third, Tesla, which is widely known to everyone, has its own set of charging standards.

The maximum capacity of the charging socket can reach 120kw, and the maximum current can reach 80A.

Fourth, in order to change the chaotic status of charging interface standards, CCS charging connector standard, namely Combined Charging System, is a composite charging system that integrates DC fast charging and AC slow charging interfaces.

Fifth, the national standard specifies in detail the connection classification methods for charging currents of 16A, 32A, 250A AC and 400A DC, mainly drawing on the standard proposed by the International Electrotechnical Commission (IEC) in 2003;

Sixth, the latest national standard is GB/T 20234-2015, which stipulates that the rated voltage of AC shall not exceed 690V, the frequency shall be 50Hz, and the rated current shall not exceed 250A; the rated voltage of DC shall not exceed 1000V, and the rated current shall not exceed 400A.

At the same time, car companies have gradually realized that "standards" are the key factors that affect the development prospects of electric vehicles. We have also seen that global charging standards have gradually moved from "diversification" to "centralization" in recent years. However, to truly achieve unified charging standards, in addition to interface standards, current communication standards are also needed. The former is related to whether the connectors match, and the latter affects whether the plug can be powered when inserted. There is still a long way to go to standardize the charging standards for electric vehicles. Car companies and governments need to further "relax their attitude" so that electric vehicles can have a future. Welcome to search for more information: OMG EV cable
