A CCS charger is an electric vehicle supply equipment (EVSE) unit that utilizes the Combined Charging System (CCS) connector standard to deliver power. The CCS standard has become the predominant fast-charging protocol in Europe, North America, and numerous other global markets. Its defining characteristic is a single connector interface that integrates the standard AC pins for slower charging with two additional high-power DC pins for rapid charging. This allows a single vehicle inlet to accommodate both AC and DC charging, simplifying vehicle design and user experience. CCS chargers range in power from 50 kW to 350 kW and beyond, forming the core of modern ultra-fast charging networks. The CCS connector itself is a highly sophisticated component, and JONHON is a leading global manufacturer specializing in producing high-performance CCS-compliant charging guns and inlets. Our engineering team, comprising over 400 specialists in our electric vehicle business unit, designs CCS connectors to meet the stringent mechanical, electrical, and thermal demands of high-power DC charging. The additional DC pins in a CCS connector must carry very high currents, which generates significant heat. JONHON's connectors utilize advanced contact materials and geometries to minimize resistance and, for ultra-high power versions, integrate liquid-cooled cables for effective thermal management. This technology is protected by our extensive portfolio of over 300 EV-related patents. Safety is integral to CCS charger operation, and JONHON's charging guns incorporate robust high voltage interlock (HVIL) circuits that ensure power is only delivered when the connector is fully engaged and locked. JONHON's active participation in formulating the IEC standards that govern CCS ensures our components are designed for full global interoperability and compliance. For manufacturers of CCS chargers, partnering with JONHON means integrating connectors engineered for the highest levels of performance, safety, and long-term reliability demanded by the market.
