The reporter learned from the Ministry of industry and information technology last week that four national standards, including electric vehicle charging interface, have been approved and issued by the "national standard announcement of the people's Republic of China No. 21, 2012" a few days ago, and will be implemented from March 1, 2012.

They are: 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; connecting devices for conductive charging of electric vehicles Part 3: DC charging interface; and communication protocol between off board conductive charger and battery management system of electric vehicles.

Relevant experts said that the release and implementation of the four national standards of electric vehicle charging interface and communication protocol will provide important technical and standard support for the construction of electric vehicle infrastructure, which is of great significance to improve China's new energy vehicle standard system, promote the demonstration pilot of new energy vehicles, and promote the coordinated development of China's new energy vehicles.

After the Ministry of industry and information technology issued four national standards, such as electric vehicle charging interface, the State Grid Corporation of China (SGCC) released on its official website in-depth regulations covering the engineering design contents of three types of electric vehicle battery charging and replacement power stations, including battery replacement station, battery distribution center and battery distribution station.

State Grid said that the release and application of in-depth regulations on three types of engineering design content is conducive to the construction of lean, standardized and standardized electric vehicle intelligent charging and swapping network, and is conducive to promoting the development of electric vehicle industry.

According to a source, the State Grid Company plans to invest more than 20 billion yuan in the development of electric vehicle charging facilities during the 12th Five Year Plan period.

Facilities construction standards first

According to the State Grid Company, the in-depth regulations cover three types of electric vehicle battery charging and replacement power station projects, including battery replacement station, battery distribution center and battery distribution station, and standardize the design and construction requirements of process flow, equipment selection, plane layout and monitoring system for battery charging, transfer and replacement of different projects.

On December 27, the Ministry of industry and information technology (MIIT) just released four national standards, including "connection devices for conductive charging of electric vehicles Part 1: General requirements" and Part 2 (AC charging interface), which are required to be implemented from March 1, 2012.

However, there is still a debate about whether the charging mode of electric vehicles is charging or changing. Some analysts pointed out that the current electric vehicle industry is facing two development bottlenecks: the sales of "complete vehicle with battery" of electric vehicles will increase the price of complete vehicle due to the high price of battery, which will affect the sales; the investment per unit area of traditional charging infrastructure is expensive, which is difficult to sustain the development, which will affect the popularity of electric vehicles.

State Grid Corporation of China (SGCC) pointed out that compared with the cost, charging efficiency, battery maintenance and circulation management, and the impact on the grid and users, the comprehensive performance of the fast switching mode is the best. Therefore, Liu Zhenya, general manager of State Grid Corporation of China, set the basic adjustment of charging facilities at the 2011 work conference. The basic business model of State Grid electric vehicle charging and swapping station is determined to be mainly power exchange, supplemented by plug-in, centralized charging and unified distribution.

This time, the design content of electric vehicle charging and swapping power station project released by state grid also mainly serves the swapping mode. According to the introduction of State Grid, the battery replacement station, battery distribution center and battery distribution station constitute the service network for efficient and fast power supplement of electric vehicles. The standardized design and construction of the three projects will reasonably solve the problems that the current battery technology does not support fast charging, the development of the electric vehicle industry is limited due to the imperfect service network, and the distribution network can not withstand large-scale random charging, The reasonable development mode of electric vehicle charging and swapping service network has been formed.

More than 20 billion yuan invested in the 12th Five Year Plan

State Grid and China Southern Power Grid are the main investment and construction enterprises of electric vehicle charging facilities. By the end of 2011, 243 charging stations and 13283 AC charging piles had been built and put into operation in China. Analysts said that although the dispute over charging mode still exists, before the large-scale production of electric vehicles, the introduction of the standard is of great significance to guide the development of the industry. In addition, although the State Grid Company tends to switch power, the investment in electric vehicle charging facilities is still charging and switching.

According to a source, State Grid Corporation of China will build 904 charging and swapping power stations and 233000 charging piles during the 12th Five Year Plan period. By the end of 2015, 1000 charging and swapping power stations and 240000 charging piles (outlets) will be built in the company's business area, basically forming a charging service network covering the company's business area to meet the needs of the development of 500000 electric vehicles.

The above-mentioned people pointed out that in order to achieve the above goals, the total investment in charging facilities during the 12th Five Year Plan period exceeded 20 billion yuan. According to the State Grid Planning, from 2011 to 2012, accelerate the construction progress and coverage of charging station and charging pile (port) pilot, accumulate relevant construction and operation experience, and meet the needs of electric vehicles in the demonstration and promotion stage; from 2013 to 2015, strengthen the network construction and operation of charging facilities, and initially build a charging service network combining charging station and charging pile (port).
