 Charging piles involve electrical energy consumption and electricity bill settlement. The accuracy of its values is directly related to the vital interests of consumers. As early as October 20, the State Administration for Market Regulation listed electric vehicle charging piles in the compulsory management directory of measuring instruments.


Among them, it is clearly stipulated that the mandatory verification of electric vehicle charging piles will be postponed to January 1, 2023, and all localities are encouraged to explore their own specific mandatory verification methods. According to the requirements of relevant laws and regulations, automobile electric charging piles are included in the "compulsory verification" supervision mode and implement "regular verification". The verification of charging piles (machines) is divided into preliminary verification, follow-up verification and in-service inspection.


The verification items of the charging pile (machine) mainly include appearance inspection, insulation resistance test, working error, indication error, payment amount error and clock indication error, after verification, the verification of the charging pile (machine) is issued by the measurement institution to issue a verification certificate, paste the verification mark in a conspicuous position, and seal the position of the internal energy meter or measurement module.


At present, the charging facilities of electric vehicles have established a unified national energy measurement standard. The State Administration for Market Regulation recently issued and implemented the new version of JJG1148-2022 "Verification Regulations for AC Charging Piles for Electric Vehicles" (for trial implementation) and JJG1149-2022 "Verification Regulations for Non-on-board Chargers for Electric Vehicles" (for trial implementation), further clarifying the measurement requirements of electric vehicle charging piles, improving applicability and on-site verification efficiency, and promoting the healthy development of the electric vehicle industry. The 2018 version will also be repealed, and this new regulation will be enforced on January 1, 2023.


Promote the research on the compulsory verification system for charging piles 


In 2021, the State Administration of Supervision pointed out in the special action circular on people's livelihood measurement that all localities will concentrate professional forces to find out the basic situation of electric vehicle charging piles in use in their regions, strengthen the research on the measurement and supervision system of electric vehicle charging piles, and explore the establishment of a new model of big data supervision. Carry out pilot projects of compulsory verification of electric vehicle charging piles in Hangzhou and Shenzhen, and promote the research on the compulsory verification system of electric vehicle charging piles.


In the pilot process, Hangzhou studied the technical indicators of electric energy meters in line with the big data model, the production and installation standards of charging piles and supporting supervision and management methods, and proposed a new intelligent supervision system integrating "remote online monitoring big data monitoring platform", "lead-sealable, anti-cheating charging pile" and "offline virtual load verification technology", which was affirmed by experts.


Anhui has tackled the project of "New Energy Vehicle Charging Facilities Online Supervision System Technology Research", and carried out online monitoring in more than 200 public charging facilities in 5 cities of Hefei, Wuhu, Chuzhou, Lu'an and Bengbu, and proved that the remote online monitoring mode of charging facilities is technically feasible and risks controllable through the comparative analysis of platform data in the past six months.


Jiangsu Wuxi actively carries out the big data supervision model, and publishes the measurement and verification information of electric vehicle charging piles on the government APP, which not only facilitates the query of the distribution of charging piles in Wuxi and the measurement verification data of each charging pile, but also gives priority to charging piles that pass the measurement verification as the object of guiding charging, which effectively improves the regulatory efficiency. 


Fujian Provincial Metrology Institute provided verification services for a total of 6,792 electric vehicle charging piles sent for inspection by 261 enterprises, effectively promoted the people's livelihood measurement project, focused on the online monitoring platform of electric vehicle charging facilities, realized the judgment of the operation status and measurement inaccuracy of electric vehicle charging facilities through big data analysis of charging facilities, effectively supervised the massive charging piles used for trade settlement, ensured that the measurement value of charging piles for operation was accurate and reliable, and settled fairly. Provide data and technical support for the implementation and formulation of relevant policies.

Many places have successively carried out compulsory verification actions for charging piles


With the continuous popularization of new energy vehicles, the scale of charging facilities is expanding, since the end of last year, various places have successively carried out mandatory verification actions for electric vehicle charging piles, from research to practice preparation, laying a solid foundation for the implementation of new standards.


The verification personnel shall verify the appearance, insulation resistance, indication error, payment amount error, etc. of the charging pile on the spot. After checking whether the name and model, manufacturer name, maximum voltage, minimum voltage, minimum current and maximum current and measurement unit on the nameplate of the charging pile are clear, and whether the technical indicators of the test output interface and communication interface used by the charging pile meet the requirements of relevant standards, the tester focuses on verifying the indication error that consumers are concerned about.


In May, the Hunan Provincial Administration for Market Supervision launched the 2022 special inspection of electric vehicle charging pile measurement, which was carried out in 14 cities and prefectures in the province for a period of 5 months. At 96 sites, 89 charging pile brands operated by 48 operators were sampled and inspected, with a total of 301 sets of charging piles. It aims to ensure the accurate and reliable timing and billing of a charging pile, the healthy and stable operation of related facilities and equipment, and jointly create a fair and just consumption environment.


Prepare for the official implementation of the compulsory verification of charging piles on January 1, 2023, lay the foundation, and take good steps, and at the same time establish and improve the fair and just electric vehicle charging pile measurement market order, and effectively protect the "money bags" of the general public. On June 21, the Kunming Municipal Market Supervision Bureau and the Yunnan Institute of Metrology and Testing Technology jointly carried out the compulsory verification of charging piles at the Delibang New Energy Vehicle Charging Station in Panlong District, Kunming City, marking the full launch of the compulsory verification of charging piles in Kunming City.


From June to August this year, the Zhengzhou Municipal Administration for Market Supervision took the lead in carrying out compulsory verification of more than 1,300 charging guns in 61 charging stations in some areas of the main urban area, exploring the formation of a complete and orderly set of compulsory verification supervision methods and verification procedures for charging piles, laying the foundation for this work next year.


Since mid-July, the Wuhan Institute of Metrology has visited 50 stations, enterprises and communities in Wuhan for a "physical examination" of new energy vehicle charging piles. In order to solve the problem that the standard machine automatically stops working due to high temperature and further improves the detection capacity, Wuhan Metrology Institute has also increased investment and purchased a special testing vehicle for charging piles to ensure that the testing work can still be carried out normally at high temperature.


On July 22, it was learned from the Qinghai Provincial Administration for Market Supervision that Qinghai has carried out supervision and inspection of the measurement management of charging piles, inspecting the filing of electric vehicle charging piles in use in various places, promoting the preparation for compulsory verification of electric vehicle charging piles, and carrying out the pilot of compulsory verification of electric vehicle charging piles.


The significance of the mandatory verification of charging piles


In recent years, with the gradual promotion of new energy vehicles, the supporting public electric vehicle charging piles have also been built and put into operation on a large scale. Charging piles involve electricity measurement and electricity bill settlement, which are closely related to the vital interests of the majority of electric vehicle consumers. It is of great significance to let consumers use the "rest assured pile", promote creditworthiness measurement, and effectively support and protect people's livelihood.


For a long time, traditional charging piles have been limited by technology, unable to seal as a whole, and easy to cheat; The operating entities of the charging pile industry are complex and diverse, with multiple levels, and disorderly competition; Lack of unified standards for products, data cannot be interconnected, and effective supervision is difficult; This has buried hidden dangers for the charging service market. Therefore, in order to maintain the measurement order of the new energy vehicle charging market, it is very important to guide and standardize the measurement behavior of market operators, and create a fair and just charging pile measurement market environment and fair charging operation competition.
