The Ministry of Industry and Information Technology organized the National Automobile Standards Committee to take the lead, Tianjin Qingyuan, Dongfeng, Chery, Changan, SAIC and other enterprises and Tsinghua University, Tongji University and other universities to participate in the development of "pure electric passenger car technical conditions" recently won the national quality supervision inspection and quarantine Approved by the General Administration and the National Standardization Administration Committee, it became the national standard (GB/T 28382-2012) and was released in the No. 9 announcement of 2012. The standard will be officially implemented on July 1, 2012.

According to reports, the standard is applicable to pure electric vehicles driven by power battery and less than 5 seats. The basic requirements for a maximum speed of 30 km/h in 30 minutes and a driving range of more than 80 km under the working condition method are proposed. Technical indicators for safety, mass distribution, acceleration performance, gradeability, low temperature performance, reliability, etc.

The relevant person in charge of the Ministry of Industry and Information Technology said that electric vehicles are one of the first pilot areas for the Ministry of Industry and Information Technology to explore a comprehensive standardization work model. The "Technical Conditions for Pure Electric Passenger Vehicles" standard collected a large amount of data during the development process and conducted in-depth experimental research. Widely solicited opinions from all walks of life. The release of the "Technical Conditions for Pure Electric Passenger Vehicles" will further standardize the research and development and production of electric vehicles in China, which will help promote the application of the electric vehicle market, strengthen the management of electric vehicles, and promote the healthy development of the electric vehicle industry.

It is understood that in recent years, the research on electric vehicle technical standards has been widely recognized in the world. The international standardization organization (ISO) and the International Electrotechnical Commission Standards System (IEC) have also accelerated the international standards related to electric vehicles. In the formulation and revision work, ISO has issued 26 standards and is in the process of revising 11 standards; IEC has issued 14 standards and is in the process of revising 16 standards. The international automotive mandatory regulatory system UN/WP29 is also accelerating the research and revision of mandatory testing of electric vehicles.

At the same time, countries such as the United States and Japan have also established their own standards and regulations for electric vehicles based on the adoption of relevant international standards. For example, the American electric vehicle standard is mainly responsible for the revision and revision work of the American Society of Automotive Engineers (SAE). 32 electric vehicle standards have been issued, and 43 standards are being revised, of which 27 are plug-in hybrid electric vehicle standards.

At the 26th World Electric Vehicle Conference held in Los Angeles in early May, Audi, BMW, Chrysler, Daimler, Ford, GM, Porsche and Volkswagen announced that they will use "unified single-port DC fast charging technology". (single-port DC-fast charging technology). Prior to this, Nissan, Toyota, Mitsubishi and Fuji Heavy Industries established the Electric Vehicle Fast Charge Association (CHAdeMO) to promote the specification, unification and popularization of electric vehicle charging device specifications and facilities, making Japan's charging technology a global standard.

China has also released relevant standards for charging systems. In December last year, the Ministry of Industry and Information Technology issued four national standards for electric vehicle charging interfaces, including "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" "Electrical Vehicle Conductive Charging Connection Device Part 3: DC Charging Interface" and "Electric Vehicle Off-Board Conductive Charger and Battery Management System Communication Protocol", which was implemented on March 1 this year.

Analysts pointed out that the use of different standards in different countries will result in differences in solutions and technologies. And technical differences will form certain barriers, which will hinder other companies. Behind the standard competition, the essence is the future market dispute. Therefore, the world's automobile powers such as the United States, Japan and Germany are competing for the standard voice of the international electric vehicle.

In response to questions about the lag of China's electric vehicle standards, Wu Zhixin, deputy director of China Automotive Technology Research Center and director of the National Automotive Standardization Technical Committee's electric vehicle sub-technical committee, said that the standardization of electric vehicles in China started earlier and has established electric vehicle standards. System framework, since the "Ninth Five-Year Plan" period, only the electric vehicle sub-standard committee has organized industry forces, and the number of electric vehicle standards that have been formulated and approved by the standardization department has reached more than 50, which is the world leader in quantity, and most of them. The standard is not behind. "The future standard system and revision will more reflect our research and development, industrialization achievements and internationalization needs. In the next two years, the relevant national standards for electric vehicles in China will reach 70 or more, and the standardization system will be further improved."
