DC Connection Unit (DCU)

The DC Charge Unit (DCU) from Stercom Power Solutions is the essential interface between high-voltage batteries and DC charging infrastructure. Designed for demanding e-mobility applications, it enables efficient and robust high-power DC charging with flexible system integration.

As part of Stercom’s charging portfolio, the DCU can be supplied either as a compact integrated solution (DCU Basic) or as a standalone, modular platform (DCU Enhanced) with scalable configuration options.

Stand-alone DC charging architecture with integrated control and communication. The DCU Enhanced directly interfaces with the DC charging station and the HV battery, reducing system complexity and enabling a compact, modular vehicle integration.

• Stand-alone DC charging unit
• AC charging controlled by the DCU Enhanced in server mode with the OBC in client mode
• Direct PLC communication with the DC charging station (EVSE)
• High-level communication compliant with DIN 70121 and ISO 15118
• Safe disconnection compliant with ISO 26262, up to ASIL B
• CAN communication following SAE J1939
• Optional insulation monitoring device (IMD) integrated
• Optional current and voltage sensors integrated
• V2X-ready

Externally controlled DC charging architecture for integrated charging systems. DCU Basic is designed to operate in combination with an external controller or OBC, enabling flexible integration into existing vehicle architectures.

• Contactor box for DC charging, perfect in combination with / controlled by Stercom OBC
• Can be integrated in any vehicle DC charging system
• Communication with the DC charging station via external power line communication (PLC) module (eg. Stercom OBC)
