Pure electric passenger car national standard implementation in July

Leaded by the Ministry of Industry and Information Technology of China National Automobile Standards Commission, Tianjin Qingyuan, Dongfeng, Chery, Chang'an, SAIC and other universities and Tsinghua University, Tongji University and other universities jointly participated in the development of the “Electric Powered Passenger Vehicle Technical Conditions” which has recently been awarded the National Quality Supervision, Inspection and Quarantine. Approved by the State Administration of Standardization and the State Administration of Standardization, it became a national standard (GB/T 28382-2012) and was published as Announcement No. 9 of 2012. The standard will be formally implemented on July 1, 2012.

According to reports, the standard applies to the use of battery-powered, 5 seats of pure electric vehicles, put forward the 30 minutes maximum speed of not less than 80 km / h, working conditions, the basic requirements of the driving range of more than 80 km, while the provision of electric vehicles Safety, quality distribution, acceleration performance, climbing performance, low temperature performance, reliability and other technical indicators.

The person in charge of the Ministry of Industry and Information Technology stated that the electric vehicle is one of the first pilot areas for the Ministry of Industry and Information Technology to explore a comprehensive standardization work model, and the “electrical passenger car technical conditions” standard has collected a large amount of data in the formulation process and conducted in-depth experimental research. , widely solicited opinions from all sectors of society. The issuance of the "Standard Specification for Pure Electric Passenger Cars" will further standardize the R&D and production of electric vehicles in China, 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 the technical standards of electric vehicles has received extensive attention worldwide, and the two International Organizations for Standardization (ISO) and the International Electrotechnical Commission (IEC) standards organizations have also significantly accelerated the international standards for electric vehicles. With regard to the formulation and revision of the work, the ISO has issued 26 standards, and 11 revisions have been made. The IEC has issued 14 standards and 16 revisions have been made. The international automotive mandatory regulatory system UN/WP29 is also accelerating the research and revision of the compulsory testing content of electric vehicles.

At the same time, countries such as the United States, Japan and Germany 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 system revision work by the American Society of Automotive Engineers (SAE). It has issued 32 standards for electric vehicles, and 43 standards are being revised. Of these, 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, General Motors, Porsche and Volkswagen have announced that they will jointly use the "universal 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 Charging Association (CHAdeMO) to promote the specification, unification, and popularization of electric car charging device specifications and facilities, making Japan's charging technology a global standard.

China has also issued relevant standards for charging systems. In December last year, the Ministry of Industry and Information Technology promulgated four national standards for charging interfaces for electric vehicles, including “Part 1: General Requirements for Conductive Charging Devices for Electric Vehicles” and “Connecting Devices for Conductive Charging of Electric Vehicles Part 2: AC Charging Interface”. , "Connecting device for conductive charging of electric vehicles Part 3: DC charging interface" and "Communication agreement between non-vehicle conducting charger and battery management system for electric vehicles", and implemented on March 1 this year.

Analysts pointed out that different countries use different standards, which will result in differences in programs and technologies. The technical differences will form a certain barrier and hinder other companies. Behind the standard competition is the future of the market, so the United States, Japan and other world automobile powers are competing for the standard of international electric vehicle discourse.

In response to doubts about the lagging standards for electric vehicles in China, Wu Zhixin, deputy director of the China Automotive Technology and Research Center and director of the Electric Vehicle Subcommittee of the National Automobile Standardization Technical Committee, stated that the development of standards for electric vehicles in our country started earlier, and electric vehicle standards have been established. As for the system framework, since the “Ninth Five-Year Plan” period, only the electric vehicle sub-agency committee has organized industrial forces, and the number of electric vehicle standards formulated and approved by the standardization authority has reached more than 50, ranking the world leader in quantity, and most The standard is not backward. "The future standards and revisions will more reflect our R&D, industrialization, and internationalization needs. In the next two years, China's national standards for electric vehicles will reach more than 70, and the standardization system will be further improved."
