2023-09-14

On September 7, 2023, the Ministry of Industry and Information Technology proposed and the National Automotive Standardization Technical Committee issued two recommended national standards: GB/T 20234.1-2023 "Conductive Charging Connection Devices for Electric Vehicles Part 1: General Requirements" and GB/T 20234.3-2023 "Conductive Charging Connection Devices for Electric Vehicles Part 3: DC Charging Interface."

Charging standards are the foundation to ensure interoperability and safe, reliable charging between electric vehicles and charging facilities. In recent years, with the increase in electric vehicle driving range and the improvement of power battery charging rates, consumers' demand for rapid vehicle energy replenishment has grown stronger. New technologies, new business models, and new demands represented by "high-power DC charging" have continuously emerged. Accelerating the revision and improvement of existing charging interface standards has become a common consensus in the industry. Based on the development of electric vehicle charging technology and the demand for fast energy replenishment, the Ministry of Industry and Information Technology organized the National Automotive Standardization Technical Committee to complete the revision of two recommended national standards, achieving a comprehensive upgrade of the original 2015 national standard scheme (commonly known as the "2015+" standard). The new standards continue to use the current domestic DC charging interface technical scheme, ensuring compatibility between new and old charging interfaces, while increasing the charging current from 250 amperes to 800 amperes and the charging power to 800 kilowatts. They add related technical requirements such as active cooling and temperature monitoring, optimize and improve test methods for mechanical performance, locking devices, and service life. This helps further enhance the environmental adaptability, safety, and reliability of conductive charging connection devices, while meeting practical needs for both low-power and high-power DC charging.

Next, the Ministry of Industry and Information Technology will organize relevant units to thoroughly promote and implement the two national standards, facilitate the application of technologies such as high-power DC charging, and create a favorable environment for the high-quality development of the new energy vehicle industry and charging facility industry.
