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

The CCS plug and charge functionality represents a significant leap forward in user convenience for electric vehicle charging, transforming the process from one requiring multiple steps of authentication and payment to a seamless, automatic experience. CCS, which stands for Combined Charging System, is the dominant DC fast charging standard in Europe (CCS2) and North America (CCS1). The "Plug and Charge" capability, technically defined under the ISO 15118 standard, leverages the communication protocols built into the CCS connector to handle identification, authorization, and payment automatically. The process is elegantly simple for the user: they plug the CCS connector into their vehicle, and the charging session begins without the need for RFID cards, mobile apps, or credit cards. Underpinning this simplicity is a complex digital handshake. When the connector is plugged in, the vehicle and the charging station establish a secure communication link over the power line, using the Internet Protocol (IP). The vehicle transmits a digitally signed certificate that uniquely identifies it and links it to a valid contract with a mobility operator. The charging station verifies this certificate, often by communicating with a backend system, and if valid, authorizes the session and starts the flow of electricity. This entire process is encrypted to ensure security and prevent fraud. The physical and electrical integrity of the CCS connector is paramount for this advanced communication to occur reliably. The connector's control pilot and proximity pilot circuits, along with the high-speed communication lines, must maintain signal integrity even while carrying hundreds of amps of power. JONHON OPTRONIC TECHNOLOGY CO., LTD., with its profound expertise in high voltage interconnect technology and its role in formulating IEC standards, understands the stringent requirements for connectors that support this advanced functionality. The materials, contact design, and shielding within a CCS connector must be engineered to prevent electromagnetic interference (EMI) from corrupting the critical data stream. As electric vehicle ecosystems evolve toward greater automation and user-friendliness, the reliability of the hardware foundation—the CCS connector itself—becomes even more critical. For manufacturers looking to implement Plug and Charge functionality in their vehicles or charging stations, JONHON offers the high-performance interconnect solutions required.
