Cctv newsOn September 7, 2023, two recommended national standards, GB/T 20234.1-2023 Connecting Devices for Conductive Charging of Electric Vehicles Part 1: General Requirements and GB/T 20234.3-2023 Connecting Devices for Conductive Charging of Electric Vehicles Part 3: DC Charging Interface, were officially released.
Charging standard is the basis to ensure the interconnection between electric vehicles and charging facilities and the safe and reliable charging. In recent years, with the increase of driving range of electric vehicles and the increase of charging rate of power batteries, consumers’ demand for rapid replenishment of electric energy for vehicles has become increasingly strong. New technologies, new formats and new demands, such as "high-power DC charging", are constantly emerging, and it has become a general consensus in the industry to speed up the revision and improvement of the relevant standards of the original charging interface. According to the development of electric vehicle charging technology and the demand for quick charging, the Ministry of Industry and Information Technology organized the National Automobile Standardization Technical Committee to complete the revision of two recommended national standards, and realized the brand-new upgrade of the original 2015 national standard scheme (commonly known as "2015+" standard). The new standard follows the current technical scheme of DC charging interface in China, ensures the universal compatibility of new and old charging interfaces, increases the maximum charging current from 250 amps to 800 amps and charging power to 800 kW, increases relevant technical requirements such as active cooling and temperature monitoring, and optimizes and perfects test methods such as mechanical performance, locking device and service life, which is conducive to further improving the environmental adaptability, safety and reliability of conductive charging connection devices, and at the same time meets the requirements of low-power and high-power DC charging.
In the next step, the Ministry of Industry and Information Technology will organize relevant units to do a good job in the promotion and implementation of the two national standards, promote the popularization and application of technologies such as high-power DC charging, and create a good environment for the high-quality development of the new energy automobile industry and the charging facility industry.
