The surging sales of new energy vehicles in China have brought to light a critical industry bottleneck - the electric vehicle charging infrastructure and interface standards. Recently, there have been two significant developments in the realm of electric vehicle charging interface standards.

Firstly, China has implemented two recommended national standards: GB/T 20234.1-2023 "Conductive Charging Coupler for Electric Vehicles Part 1: General Requirements" and GB/T 20234.3-2023 "Conductive Charging Coupler for Electric Vehicles Part 3: Direct Current Charging Interface." The most noteworthy change in these new standards is the substantial increase in the maximum charging current, from 250 amperes to 800 amperes, accompanied by an upgrade in power to 800 kilowatts.

Secondly, China recently released a set of new standards related to electric vehicle charging. These standards are so-called "ChaoJi" standards, including GB/T18487.1-2023 "Electric Vehicle Conductive Charging System Part 1: General Requirements," GB/T27930-2023 "Digital Communication Protocol Between Non-Vehicle-Mounted Conductive Chargers and Electric Vehicles," and GB/T 20234.4-2023 "Connecting Devices for Electric Vehicle Conductive Charging Part 4: High-Power DC Charging Interface". Compared to existing standards, the ChaoJi charging standards have made significant enhancements in mechanical safety, electrical safety, protection against electrical shock, and fire and thermal safety. The cable components have been adapted with a liquid cooling method and an added temperature monitoring system, which will further enhance the environmental adaptability, safety, and reliability of conductive charging connection devices. These standards are scheduled to be implemented on April 1, 2024.
