4:1 charging pile construction will usher in the outbreak

According to data reported by charging alliance companies, as of the end of June, the nation’s public charging piles totaled 81.78 million, an increase of 65% from the end of 2015, and the number of private charging piles built with the vehicles was 55.378 million, a year-on-year increase of 12%. The ratio of piles basically reaches 4:1.

In the face of a 4:1 ratio, Liu Yongdong, deputy director of the Standardization Management Center of the China Electricity Council, did not seem satisfied. He said at the first China Charging Pile Innovation Summit on July 27th that the National Development and Reform Commission was held on November 17 last year. The National Energy Administration, the Ministry of Industry and Information Technology, and the Ministry of Housing and Urban-Rural Development jointly issued the “Guidelines for the Development of Electric Vehicle Charging Infrastructure (2015-2020)”, proposing that 4.8 million piles and 12,000 stations will be constructed by 2020, and the proportion of vehicle piles will be 1:1. . It can be seen that the development space from 4:1 to 1:1 is very huge. The construction of charging infrastructure will usher in rapid growth in the next five years.

Charging pile

The construction of charging piles in China is at the peak of industrial development. After several years of efforts, standard work has achieved certain results. The standard system for the construction of charging facilities has basically been established, and key standards have been issued in succession to basically meet the needs of the development of charging facilities. The standard system covers inspection specifications and becomes the basic conditions for procurement of equipment by various operators, which is conducive to standardizing the quality of charging facilities.

According to Liu Yongdong, the current charge interface and communication protocol standard architecture has been completed. The charging interface and communication protocol standards developed according to China's national conditions were released at the end of 2011 and implemented in March 2012. It mainly includes three charging interface series standards and DC charging communication protocol standards. The current 2015 series of upgrade standards has been released.

In terms of key equipment standards for charging facilities, electric vehicle AC charging piles, DC chargers, and on-vehicle conduction chargers have been approved for release in 2010. The series of inspection and test specifications for charging equipment for electric vehicles was also approved in 2013. It also initiated the compilation of nine charging station construction standards, including the design, construction, construction, and acceptance of charging stations, including the "General Requirements for Electric Vehicle Charging Stations." In the area of ​​charge standard and charging facility operation and maintenance standards, a series of standards including operation metering, operation monitoring and operation platform communication, and signage identification were formulated.

Liu Yongdong said that these standards are playing a positive role. At present, interface standards are gradually unifying, and charging equipment standards have become the basis for manufacturers to manufacture products and bids for corporate procurement. Fortunately, in the new energy vehicle purchase tax reduction and exemption measures, whether it meets China's charging interface standards and communication protocols are also included in the conditions.

Liu Yongdong said that the next step in charging standards is to improve the interconnection of information standards. The first is to establish a national unified coding standard to solve the problem of pile coding, and to establish a unified information exchange standard system, namely, “Exchange Standard for Information Exchange of Electric Vehicle Charging and Power Exchange Service”. This standard can meet the government's effective statistics and meet operators and operators. Exchange of facilities services and exchange of charging processes are provided to satisfy owners' charging queries. It contains four parts: general rules, public information exchange specifications, business information exchange specifications, data transmission, and security. It is divided into four levels, namely, the information access layer. Information for cars can also be information for charging cards. The infrastructure layer is Charging pile information; operating service layer and data sharing layer. After the implementation of the standard, owners use the current mobile phone roaming to solve related problems. Solve the standard charging process and build a standard cross-platform charging process between two operators. To solve the problem of identification, each owner can know who the operator is after charging to another operator. The user's charging charges are still paid to the original operator, and the settlement of the background is resolved by the two operators themselves. According to Liu Yongdong’s introduction, the standard has previously completed public solicitations through the Internet. Currently, standard pilots have been conducted in Beijing, Shanghai, and Shenzhen. Major domestic operators have participated in the verification of standards. It is expected that the information exchange standards will be formally announced to the public in September. Operators follow this set of rules.

Next, a unified national information publication platform was established. According to Liu Yongdong, the main task of the national-level charging service information platform is to provide statistics and provide basic public services. It is necessary to establish an information reporting system between the operation management systems of various local governments and various operators and national information platforms so as to realize information interconnection and interconnection of charging services. Through the reporting system, the national information platform can complete the statistical analysis of the existing charging infrastructure data, scientifically and accurately collect data on the charging infrastructure at different times and in different places, and make timely announcements to the public. Through the reporting system, it is possible to unify the charging infrastructure data, provide the society with authoritative and comprehensive basic information on charging facilities, and achieve maximum sharing of charging facility resources.
