China's four standards for electric vehicles will promote car network docking

According to information from the Department of Equipment and Industry of the Ministry of Industry and Information Technology, the four national standards for charging interfaces and communication protocols for electric vehicles jointly drafted by various departments were approved for release on December 22 and will be implemented on March 1 next year.

A related person from the Ministry of Industry and Information Technology said that the issuance of four new standards has filled the gaps in the relevant standards for domestic charging facilities and will promote the effective docking of vehicle manufacturing with the construction of power grids and further promote the promotion of new energy vehicles.

Promote car network docking

The four new national standards announced this time all pointed to the connection devices for the construction of complete vehicles and power grids in an effort to establish a unified standard and end the chaotic and mutually incompatible chaos of new energy vehicles in various fields. Bureau. According to industry insiders, this move is an important measure to further promote the promotion of new energy vehicles after the promotion of energy conservation and new energy vehicle demonstration and promotion by the four ministries and commissions.

According to the information from the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology, the National Energy Administration, and the China National Automobile Technology Research Center have taken the lead in the standardization of the overall deployment of electric vehicle charging facilities in China and coordinated and supported by the National Standardization Committee. The Electric Power Enterprise Confederation and the Electric Apparatus Research Institute jointly drafted "Connecting Devices for Conductive Charging of Electric Vehicles Part 1: General Requirements", "Connecting Devices for Conductive Charging of Electric Vehicles Part 2: AC Charging Interface", and "Conduction Conductive Charging of Electric Vehicles". "Connecting Devices Part 3: DC Charging Interface" three national standards; the National Energy Administration, the Ministry of Industry and Information Technology, the Electric Power Enterprise Federation and the Steam Research Center co-authored the "Electric Vehicle Non-Car Conveying Charger and Battery Management System Communication Protocol" National Standard.

A related person from the Ministry of Industry and Information Technology told the China Securities Journal that the publication and implementation of the four national standards for charging interfaces and communication protocols for electric vehicles is mainly to provide important technical and standard support for the construction of electric vehicle infrastructure, and to achieve the connection between the automobile and the power grid.

Industry analysts and unified interfaces mean that consumers who purchase new energy vehicles can charge at any charging station without having to worry about interface matching. This will help solve the worries of consumers purchasing new energy vehicles, and further promote and promote the demonstration operation and market promotion of new energy vehicles in China.

Cross-cutting cooperation

The four new standards announced this time involve the three major fields of automotive, energy and electrical engineering. Industry insiders believe that it is the first time for China to jointly develop common standards across multiple sectors, showing that the cooperation mechanism and coordination model of all parties involved in electric vehicles has made great progress. It is of great significance to the development of new energy vehicles.

All along, the development of new energy vehicles in China has been hampered by the multi-interest game of related parties such as vehicle manufacturers and power grid companies, in addition to being subject to no major breakthroughs in core technologies. Although all parties agree that the joint promotion can truly promote the development of new energy vehicles, all parties in the “cooperation” are disguised and artificially hindered the demonstration and promotion of new energy vehicles and market sales. The four standards announced this time are all for the intersection of new energy vehicles and related parties for the intersection of electric vehicles and conductive charging connection devices.

The Ministry of Industry and Information Technology also stressed that the four standards are the basis for the development of new energy vehicles, but new energy vehicles must really achieve substantive development, but also to solve the various aspects involved in the production of new energy vehicles and the exchange of electricity infrastructure construction.
