Conventional vehicle-side high-power charging systems have traditionally consisted of several individual components, including a CCS inlet, an external charging controller, and extensive cabling. This architecture requires installation space, increases complexity, and introduces additional sources of error.

Charx connect advanced from Phoenix Contact, a specialist in electrical engineering, electronics, and automation based in Blomberg, Lippe, now combines the mechanical components with the vehicle-side communication and charging control functions into a single unit for the first time. PLC communication and all relevant charging protocols are processed directly within the inlet. The “external charging controller” system component previously required is completely eliminated, as are numerous interfaces and cabling points. The result, according to the manufacturer: a highly integrated, efficient, and robust system.

Integrating the controller into the inlet offers significant advantages for system integrators and vehicle manufacturers of electric buses, trucks, and commercial vehicles. Installation space requirements and system weight are reduced, while the reduction in interfaces simultaneously minimizes potential sources of error. Connection is simple and reliable via defined CAN interfaces, complemented by well-designed service and diagnostic concepts from a single source. In addition, the modular design of the cable outlets—available either straight or at a 90-degree angle to the left or right—enables flexible integration into various vehicle architectures. This makes Charx connect advanced suitable for a wide range of vehicle segments—from city buses and long-haul trucks to construction and municipal vehicles.

For use in heavy-duty applications, the inlet is designed for high power. Charx connect advanced supports charging capacities of 800 amps in Boost Mode and meets all relevant standards and safety requirements: ISO 15118 and DIN 70121, VDV 261 for bus applications, functional safety up to ASIL B in accordance with ISO 26262, and preparation for UNECE R155/R156 (cybersecurity).

Another advantage is the ease of maintenance offered by Charx connect advanced: The pluggable high-voltage cables allow for tool-free replacement of the inlet without having to open cooling circuits or adjacent vehicle assemblies. This reduces service times, increases vehicle availability, and lowers the total cost of ownership. Samples of the Charx connect advanced CCS inlet are available now and can be ordered for testing and integration projects. Series production of the fully production-ready product is scheduled for the third quarter of 2026.
