The construction of charging piles will usher in an explosion period

according to the data reported by charging alliance enterprises, by the end of June, the total number of public charging piles nationwide had reached 817800, an increase of 65% over the end of 2015, and 5537800 private charging piles were built with vehicles, an increase of 12% over the same period in 2015. At present, the ratio of vehicles to piles has basically reached 4:1

facing the ratio of 4:1, Liu Yongdong, deputy director of the standardization management center of the China Electricity Council, seemed dissatisfied. He said at the first China charging pile Innovation Summit on July 27 that on November 17 last year, the national development and Reform Commission, the national energy administration, the Ministry of industry and information technology, and the Ministry of housing and urban rural development jointly issued the development guide for electric vehicle charging infrastructure (year), proposing to build 4.8 million piles and 12000 stations by 2020, The ratio of car piles reaches 1:1. It can be seen that the development space from 4:1 to 1:1 is very huge, and the charging infrastructure construction will usher in rapid growth in the next five years

the construction of charging piles in China is at the peak of industrial development. Through several years of efforts, certain achievements have been made in the standard work. The standard system for the construction of charging facilities has been basically established, and key standards have been issued one after another, which can basically meet the needs of the development of charging facilities. The standard system covers the testing specifications, which has become the basic condition for operators to purchase equipment, and is conducive to standardizing the product quality of charging facilities

according to Liu Yongdong, the standard architecture of charging interface and communication protocol has been completed. The charging interface and communication protocol standards formulated according to China's national conditions have been 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. At present, the 2015 series upgrade standard has been released

in terms of standards for key equipment of charging facilities, electric vehicle AC charging piles, DC chargers and on-board conductive chargers have been approved for release in 2010 when data cannot be measured, and the series of inspection and test specifications for electric vehicle charging equipment has also been approved for release in 2013. The compilation of 9 charging station construction standards, including the general requirements for electric vehicle charging stations, including the design, construction, construction and acceptance of charging stations, was also initiated. In terms of power exchange standards and charging facility operation and maintenance standards, a series of standards including operation measurement, operation monitoring and operation platform communication, signs and identifications have been formulated

Liu Yongdong said that these standards are playing an active role. At present, the interface standards are gradually unified, and the charging equipment standards have become the basis for manufacturers to manufacture products and the bidding documents for enterprises to purchase. Fortunately, the compliance with China's charging interface standards and communication protocols are also included in the new energy vehicle purchase tax reduction measures

Liu Yongdong said that the focus of the next charging standard work is the improvement of information interconnection standards. The first is to establish a national unified coding standard to solve the coding problem of piles, and build a unified information exchange standard system, that is, the information exchange standard for electric vehicle charging and changing service. This standard can meet the effective statistics of the government, meet the needs of operators and operators, and will bring a breakthrough transformation for China's EPS industry. The facility service exchange and charging process exchange between providers will meet the charging inquiry of vehicle owners. It includes 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. The information for the car can also be the information of the charging card; The infrastructure layer is the information of the charging pile; The operation service layer and data share the same, and it will not be particularly easy to fade in the case of collision. After the implementation of the standard, car owners use the current roaming method to solve relevant problems. Solve the standard charging process and build a cross platform standard charging process for two operators. To solve the problem of identity recognition, each car owner can know who the operator is after charging at another operator. The user's charging fee is still paid to the original operator, and the background settlement is solved by the two operators themselves. According to Liu Yongdong, the standard has previously completed the public consultation work by saying in the form of a network where the experimental machine is the most famous. At present, the standard pilot has been carried out in Beijing, Shanghai and Shenzhen. Major domestic operators have participated in the standard verification. It is expected that the information exchange standard will be officially announced to the society in September, and all operators will follow this set of rules

secondly, establish a unified national information release platform. According to Liu Yongdong, the main task of the national charging service information platform is to count and provide basic public services. It is necessary to establish an information submission system between the operation management system of local governments, operators and enterprises and the national information platform to realize the information interconnection of charging services. Through the submission system, the national information platform can complete the statistical analysis of the existing charging infrastructure data, scientifically and accurately count the charging infrastructure data in different periods and places, and publish them to the public in a timely manner. Through the submission system, we can realize the unification of charging infrastructure data, provide authoritative and comprehensive basic information of charging facilities to the society, and realize the maximum level sharing of charging facilities resources
