EV Charging Connectors: CCS2, Type2 & GB/T Solutions

The existence of a unified ev charging connector standard is fundamental to the interoperability, safety, and widespread adoption of electric vehicles globally. However, the reality is a landscape of several key regional and application-specific standards that define the physical interface, communication protocols, and safety requirements between the electric vehicle and the charging station. The primary standards are developed by organizations like the International Electrotechnical Commission (IEC), the Society of Automotive Engineers (SAE), and the Chinese Guobiao (GB/T) standards. The IEC 62196 standard, for instance, defines the specifications for plugs, socket-outlets, vehicle connectors, and vehicle inlets for conductive charging of electric vehicles. Within this framework, different physical configurations are defined, such as the IEC Type 1 (based on SAE J1772) for AC charging in North America and Japan, and the IEC Type 2 for AC charging in Europe. For DC fast charging, the Combined Charging System (CCS) extends these AC standards by adding additional power contacts, while CHAdeMO represents a different DC fast charging standard originating from Japan. In China, the GB/T standard defines both AC and DC charging interfaces. Each standard meticulously specifies pin assignments, dimensions, communication protocols (such as the control pilot signal), and safety mechanisms like the locking actuator and proximity detection to ensure the vehicle cannot be driven away while plugged in. JONHON OPTRONIC TECHNOLOGY CO., LTD. is not merely a follower but an active contributor to this standardization process, having formulated 7 IEC standards and over 10 Chinese standards. This deep involvement ensures that JONHON's high voltage interconnect solutions, including vehicle inlets and charging cable assemblies, are designed from the ground up for full compliance with the relevant global standards. For manufacturers developing EVs or charging infrastructure for different markets, navigating these standards is complex. Partnering with a component supplier like JONHON, which possesses intrinsic knowledge of the standards and a proven track record in designing compliant products, significantly de-risks the development process and accelerates market entry.
