Recently, the State Administration for Market Regulation officially approved the establishment of the "National Electric Vehicle Battery and Charging System Industry Measurement and Testing Center" in Shenzhen. The environmental adaptability laboratory of the center can test the energy consumption and range of electric vehicles, and complete the condition testing of power batteries at different environmental temperatures. Since its approval for establishment in September 2018, the National Electric Vehicle Battery and Charging System Industry Measurement and Testing Center has carried out testing and evaluation of key parameter values of power batteries, battery consistency, etc. Through in-depth research on measurement and testing technology methods, it has taken the lead in achieving "remote measurement" of electric vehicle charging piles, and established a big data platform for charging pile measurement, connecting more than 120000 charging piles, The innovative transformation of charging station measurement mode has been achieved through measurement data. Liu Tiedong, President of Shenzhen Institute of Metrology and Quality Testing: We will focus on solving the pain points and difficulties of "inability to measure, incomplete measurement, and inaccurate measurement" in the industry, and fully leverage the role of metrology as a fundamental support and guarantee. Shenzhen has gathered key electric vehicle and charging facility enterprises such as BYD and Huawei, with a solid policy, industry, and measurement foundation. As of now, Shenzhen has built 6 national level measurement platforms, established 477 social public measurement standards, and established 1794 highest measurement standards for enterprises. Zhang Wen, Deputy Director of the Metrology Department of the Shenzhen Municipal Market Supervision Bureau: With the support of this center, the Shenzhen Municipal Market Supervision Bureau will innovate intelligent regulatory methods such as measurement data verification, and take the lead in exploring and solving the problem of measurement rules for overcharging facilities nationwide, providing comprehensive and accurate measurement and testing services for upstream and downstream enterprises in the electric vehicle industry, as well as enterprises engaged in the production, construction, and operation of overcharging facilities.
