On December 28, 2023, SAC approved the development plan for the mandatory national standard "Minimum allowable values of energy efficiency and energy grades for electric vehicle conductive charging system." The standard will be developed under the leadership of the National Energy Infrastructure and Management Standardization Technical Committee (SAC/TC20), with a development period of 22 months.

With the rapid development of the electric vehicle industry, as of the end of 2022, China's domestic stock of new energy vehicles reached 13.1 million, and the charging infrastructure stock reached 5.21 million units, with a ratio of charging poles to vehicles reaching 2.5:1. As one of the "Seven New Infrastructures" (5G, UHV power transmission, inter-city high-speed railways and urban rail transit, charging stations, data centers, artificial intelligence, and industrial Internet), the charging infrastructure stock in China is expected to grow tenfold by 2030, with a potential market size exceeding one trillion Chinese yuan.

The rapid growth in the stock of charging infrastructure has brought about significant energy consumption and increased environmental pollution. Faced with the expected demand for energy replenishment for 100 million new energy vehicles by 2030, the potential energy-saving scale of charging stations is enormous, but currently, there are no related energy efficiency standards domestically or internationally. To address this issue, SAC proposes the development of mandatory energy efficiency standards for charging stations, aiming to promote technological progress in energy conservation, improve the energy efficiency of charging products, reduce harmful emissions, and protect the environment.

This new standard will specify energy efficiency evaluation indicators, special temperature efficiency assessments, and energy efficiency test methods for direct current (DC) and alternating current (AC) charging equipment for electric vehicles. The standard will apply to non-vehicle-mounted conductive charging equipment for electric vehicles, including non-vehicle-mounted chargers, AC charging stations, and electric vehicle charging connectors, with a maximum rated voltage of 1000 V AC or 1500 V DC and a maximum rated output voltage of 1000 V AC or 1500 V DC.

The English version of this standard will be developed simultaneously.
