CCTV News:The website of the Ministry of Industry and Information Technology reported on September 26 that on September 25, the standard review meeting of the Electric Vehicle Sub-technical Committee of the National Automobile Standardization Technical Committee was held in an online and offline way. More than 90 members, observers and experts from the standard drafting unit attended the meeting. The meeting reviewed and adopted two national standards, GB/T 20234.1 "Connecting devices for conducting charging of electric vehicles Part 1: General requirements" and GB/T 20234.3 "Connecting devices for conducting charging of electric vehicles Part 3: DC charging interface".
Charging standard is the basis to ensure the interconnection between electric vehicles and charging facilities and the safe and reliable charging. At present, with the increase of driving range of electric vehicles and the increase of charging rate of power batteries, consumers’ demand for quick replenishment of electric energy for vehicles is increasingly strong, and new technologies and formats such as "high-power DC charging" and "V2G (vehicle-network interaction)" are constantly emerging. It has become a general consensus in the industry to speed up the revision and improvement of the current charging interface standards. Based on the current technical scheme of DC charging interface in China, the two standards have improved the rating of charging voltage and current, increased the technical requirements of high-power charging related functions such as active cooling and temperature monitoring, and optimized and improved the test methods of mechanical performance, locking device and service life. This revision will further enhance the environmental adaptability, safety and reliability of conductive charging connection devices, effectively meet the development of high-power charging technology and market demand, ensure the universal compatibility of new and old charging interfaces, and create a good environment for the high-quality development of new energy automobile industry and charging facilities industry.
