On September 7, 2023, GB/T 20234.1-2023 "Connecting Devices for Conductive Charging of Electric Vehicles Part 1: General Requirements" and GB/T 20234.3-2023 were proposed by the Ministry of Industry and Information Technology and under the jurisdiction of the National Technical Committee for Automotive Standardization. Two recommended national standards "Connecting Devices for Conductive Charging of Electric Vehicles Part 3: DC Charging Interface" were officially released.
Charging standards are the basis for ensuring the interconnection between electric vehicles and charging facilities as well as safe and reliable charging. In recent years, as the driving range of electric vehicles increases and the charging rate of power batteries increases, consumers have an increasingly strong demand for vehicles to quickly replenish electric energy. New technologies, new business formats, and new demands represented by "high-power DC charging" continue to Emerging, it has become a general consensus in the industry to speed up the revision and improvement of the original standards related to charging interfaces. According to the development of electric vehicle charging technology and the demand for rapid recharge, 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 new upgrade to the original 2015 version of the national standard scheme (commonly known as the "2015 +" standard). While following my country's current DC charging interface technical solution and ensuring universal compatibility of new and old charging interfaces, the new standard increases the charging current from 250 amps to 800 amps and the charging power to 800 kilowatts, and adds active cooling, temperature monitoring and other related technologies. According to the requirements, the test methods such as mechanical properties, locking devices and service life have been optimized and improved, which will help further improve the environmental adaptability, safety and reliability of the conductive charging connection device, and at the same time meet the actual needs of DC low power and high power charging. .
Next, the Ministry of Industry and Information Technology will organize relevant units to deepen the promotion and implementation of the two national standards, promote the promotion and application of high-power DC charging and other technologies, and create a good environment for the high-quality development of the new energy vehicle industry and charging facility industry.
