EV Charging Connectors & Solutions | JONHON B2B

A CCS1 charger is an electric vehicle supply equipment (EVSE) unit that utilizes the Combined Charging System (CCS) Type 1 connector standard to deliver high-power DC fast charging. This standard is the mandated DC fast charging interface for electric vehicles in North America. The CCS Combo 1 connector is ingeniously designed by taking the standard five-pin AC Type 1 (SAE J1772) connector and adding two high-power DC pins below it within the same overall envelope. This allows a single vehicle inlet to accept both AC Level 1/2 charging and DC fast charging, simplifying vehicle design and the user experience. CCS1 chargers typically operate at power levels ranging from 50 kW to 350 kW, enabling compatible vehicles to recharge their batteries to 80% capacity in a timeframe of 20-60 minutes, which is essential for enabling long-distance travel. JONHON is a leading global manufacturer specializing in the production of high-performance CCS1 charger components, particularly the charging guns and inlets that form the critical high-power interface. Our CCS1 charging guns are engineered to meet the unique demands of the North American market and the extreme electrical and thermal stresses of high-power DC charging. With a dedicated team of over 400 engineers in our electric vehicle business unit and a portfolio of over 300 EV-related patents, JONHON has developed advanced connector technologies for this application. This includes precision contact systems for the high-power DC pins to minimize resistance and heat, and for ultra-fast charging levels, integrated liquid-cooled cables to actively manage thermal loads for safe, sustained operation. Safety is paramount in the high-voltage environment of a CCS1 charger. JONHON's connectors incorporate robust high voltage interlock (HVIL) circuits that constantly monitor connection integrity, ensuring the high-voltage circuit is only energized when the gun is fully engaged and locked, preventing dangerous arcing. JONHON's deep engineering expertise, demonstrated through our active participation in formulating IEC standards (which influence global CCS norms) and our over 300 EV-related patents, ensures our CCS1 components are designed for reliability, safety, and interoperability. For manufacturers producing DC fast charging stations for the North American market, integrating JONHON's proven CCS1 charging guns is fundamental to delivering a safe, reliable, and competitive product.
