The national standard for pure electric passenger vehicles will be officially implemented on July 1st

Led by the National Automobile Standards Committee organized by the Ministry of Industry and Information Technology, Tianjin Qingyuan, Dongfeng, Chery, Chang'an, SAIC and other enterprises, as well as Tsinghua University, Tongji University and other universities jointly formulated the "Technical Conditions for Pure Electric Passenger Vehicles" recently won the National Quality Supervision, Inspection and Quarantine Approved by the State Administration of Standardization and the National Standardization Management Committee, it became a national standard (GB/T 28382-2012) and was released as Announcement No. 9 of 2012. This standard will be formally implemented on July 1, 2012.

According to reports, the standard is applicable to pure electric vehicles with less than 5 seats powered by a power battery. It proposes the basic requirements of a 30-minute high speed not less than 80 km/h and a driving range greater than 80 km under the working condition method. It also stipulates electric Technical indicators for vehicle safety, quality distribution, acceleration performance, climbing performance, low temperature performance, reliability, etc.

The relevant person in charge of the Ministry of Industry and Information Technology stated that electric vehicles are one of the pilot areas for the Ministry of Industry and Information Technology to explore a comprehensive standardization work model. During the formulation of the "Technical Conditions for Pure Electric Passenger Vehicles" standard, a large amount of data was collected and in-depth experimental research was carried out. Solicit opinions from all walks of life. The release of the "Technical Conditions for Pure Electric Passenger Vehicles" standard will further regulate the development and production of electric vehicles in China, which will help promote the application of electric vehicles in the 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. The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) have also significantly accelerated the international standards related to electric vehicles. ISO has issued 26 standards and is preparing and revising 11 standards; IEC has published 14 standards and is preparing and revising 16 standards. UN/WP29, the international mandatory regulatory system for automobiles, is also speeding up the research and revision of the mandatory testing content for electric vehicles.

At the same time, the United States, Japan, Germany and other countries have also established their own standards and regulations for electric vehicles on the basis of adopting relevant international standards. For example, the American Society of Automotive Engineers (SAE) is mainly responsible for the revision of the American electric vehicle standards. 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 the United States in early May, eight car companies, Audi, BMW, Chrysler, Daimler, Ford, GM, Porsche and Volkswagen, announced that they would jointly use the "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 Charging Association (CHAdeMO) to promote the standardization, unification and popularization of electric vehicle charging device specifications and facilities, and to make Japan's charging technology a unified 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 such as the charging interface for electric vehicles, including "Connecting Devices for Conductive Charging of Electric Vehicles Part 1: General Requirements" and "Connecting Devices for Conductive Charging of Electric Vehicles Part 2: AC Charging Interfaces" , "Connecting Device for Conductive Charging of Electric Vehicle Part 3: DC Charging Interface" and "Communication Protocol between Electric Vehicle Off-board Conductive Charger and Battery Management System", which will be implemented on March 1 this year.

Analysts pointed out that different countries use different standards, which will cause differences in solutions and technologies. However, technological differences will create certain barriers and hinder other companies. Behind the competition for standards is the future market competition. Therefore, the world's automotive powers such as the United States, Japan and Germany are all vying for the right to speak in international electric vehicle standards.

In response to the community’s doubts about China’s lagging standards for electric vehicles, Wu Zhixin, deputy director of the China Automotive Technology Research Center and director of the Electric Vehicle Sub-committee of the National Automotive Standardization Technical Committee, said that China’s electric vehicle standards started early and the standards for electric vehicles have been formulated. The system framework. Since the "Ninth Five-Year Plan" period, only the electric vehicle sub-standard committee has organized industry forces, formulated and approved and issued more than 50 electric vehicle standards by the standardization authority, which ranks in the world in terms of quantity, and most of them The standard does not lag behind. "Future standard formulation and revision will more reflect our R&D, industrialization achievements and international needs. In the next two years, China's electric vehicle-related national standards will reach more than 70, and the standardization system will be further improved."
