On December 28, AQSIQ, the National Standards Commission, the National Energy Administration, the Ministry of Industry and Information Technology, the Ministry of Science and Technology and other departments jointly issued five newly revised national standards for electric vehicle charging interfaces and communication protocols, and the new standards will be implemented
from January 1 next year.
The revision of the five standards comprehensively improves the safety and compatibility
of charging.
In terms of safety, the new standard adds functions such as charging interface temperature monitoring, electronic lock, insulation monitoring and discharge circuit, refines the safety protection measures of DC charging vehicle interface, and clearly prohibits the application of unsafe charging mode, which can effectively avoid accidents such as electric shock and equipment combustion, and ensure the safety of
electric vehicles and users during charging.
In terms of compatibility, the type and structure of AC and DC charging interface are compatible with the original standard, the new standard modifies some contacts and mechanical lock sizes, but the new and old plug sockets can cooperate with each other, the electronic locking device added by the DC charging interface does not affect the electrical connection between the new and old products, and the user only needs to update the communication protocol version to realize the new power supply equipment and electric vehicles can ensure the basic charging function
.
At present, China's national standards such as DC interface, control guidance circuit, and communication protocol for electric vehicles are listed as the world's four major DC charging interface standards together with the United States, Europe and Japan, which has significantly enhanced China's influence
in the field of international charging and swapping.
