Integrated CCS Charging Inlet Simplifies HPC Architecture

Phoenix Contact has launched the CHARX connect advanced CCS charging inlet, integrating the complete vehicle charging controller directly into the inlet housing. The solution is designed for heavy electric vehicles, including buses, trucks and utility vehicles, and aims to reduce system complexity while supporting high-current charging applications.

Integrated Charging Control and PLC Communication
In conventional High Power Charging (HPC) architectures, the vehicle-side system typically comprises a CCS charging inlet, a separate external charging controller and associated wiring harnesses. This distributed configuration increases installation space requirements and interface complexity.

CHARX connect advanced integrates the vehicle charging controller into the production-ready CCS inlet. Power Line Communication (PLC) and all relevant charging protocols are processed directly within the component. By eliminating the external charging controller and associated cabling, the system reduces potential error sources and simplifies electrical architecture.

The charging inlet supports ISO 15118 and DIN 70121 communication standards, enabling compatibility with current and next-generation DC charging infrastructure.

High Current Capability for Heavy-Duty Applications
The inlet is engineered for High Power Charging up to 800 A in Boost Mode, addressing the requirements of heavy-duty electric vehicles with large battery capacities. High current capability is essential for reducing charging times in depot or corridor charging scenarios.

The product also aligns with VDV 261 requirements for electric bus applications and supports functional safety up to ASIL B in accordance with ISO 26262. Preparation for UNECE R155 and R156 addresses cybersecurity and software update compliance in regulated markets.

Reduced Integration Effort for OEMs
By consolidating charging mechanics and control electronics into a single component, the system reduces installation space and overall system weight. Defined CAN interfaces provide straightforward integration into vehicle control systems, supported by unified service and diagnostic concepts.

The modular design of cable outlets—available straight or at 90° angles to the left or right—enables flexible packaging in different vehicle architectures. This adaptability supports applications ranging from city buses and long-haul trucks to construction and municipal vehicles.

Serviceability and Lifecycle Efficiency
The charging inlet incorporates detachable high-voltage cables, enabling tool-free replacement without opening cooling circuits or adjacent assemblies. This design reduces maintenance time and increases vehicle availability.

By minimizing interfaces, simplifying architecture and enabling faster service operations, CHARX connect advanced is positioned to lower total cost of ownership across the vehicle lifecycle while supporting scalable deployment of high-power CCS charging in heavy-duty electrified fleets.
