Beijing Metrology Institute "Electric Vehicle Charging Equipment DC Metering Device" Received Acceptance

[China Instrument Network Instrument R&D] Recently, the evaluation experts organized by the Beijing Municipal Science and Technology Commission carried out the acceptance of the subject of “Research on the Development and Verification Technology of Electric Vehicle Charging Device DC Metering Device” undertaken by the Beijing Institute of Metrology and Inspection Science.

After material review and site visits, experts agreed that the research on the development and verification of DC metering devices for electric vehicle charging equipment is of great significance to the promotion of electric vehicle infrastructure construction in Beijing. The main assessment indicators of the project met the requirements of the mission statement. The acceptance data was complete and standardized, and the funds were used reasonably. The project passed the acceptance of the expert group.

During the R&D process, the research group established a simulation platform for the electric vehicle charging room, successfully developed a DC charger with DC power meter with independent intellectual property rights, developed a DC meter standard set, and tested the DC charging machine for electric vehicles on site. A set of devices. Can be the first in the country to carry out all the parameters of the laboratory parameters of the DC charger test and DC charging machine on-site detection. At the same time, the DC measurement technology for electric vehicle charging equipment was studied, and 2 local measurement technical specifications and 2 patents were formulated in Beijing.

Under the auspices of the project, in 2016 Beijing Municipality took the lead in implementing the DC metering method for DC charging of electric vehicles at the input port, and using the results of the project to cooperate with the Beijing Municipal Development and Reform Commission, the Housing and Construction Commission and other government departments, and involved in the public service industry. The common DC charger performs metering tests. It provides measurement support for the commercialization of charging facilities, provides technical basis for regulating the design, production, and acceptance of energy metering devices for charging and charging meters, and promotes the development and application of electric vehicles and charging equipment industries. In order to further implement the "Circular of the State Council on Printing and Distributing Energy-saving and New Energy Vehicle Industry Development Plan (2012-2020)" (Guofa [2012] No. 22) and "Guiding Opinions of the General Office of the State Council on Accelerating the Popularization and Application of New Energy Vehicles" ( The spirit of the document issued by the State Administration of Industry Development (2014) No. 35) laid a solid foundation for accelerating the healthy development of the new energy automotive industry.
